# Upgrading to newer versions of Roundup

Please read each section carefully and edit the files in your tracker home accordingly. Note that there is information about upgrade procedures in the administration guide in the Software Upgrade section.

If a specific version transition isn’t mentioned here (e.g. 0.6.7 to 0.6.8) then you don’t need to do anything. If you’re upgrading from 0.5.6 to 0.6.8 though, you’ll need to apply the “0.5 to 0.6” and “0.6.x to 0.6.3” steps.

General steps:

> 1. Make note of your current Roundup version.

> 2. Take your Roundup installation offline (web, email, cron scripts, roundup-admin etc.)

> 3. Backup your Roundup instance

> 4. Install the new version of Roundup (preferably in a new virtual environment)

> 5. Make version specific changes as described below for each version transition. If you are starting at 1.5.0 and installing to 2.3.0, you need to make the changes for all versions starting at 1.5 and ending at 2.3. E.G. 1.5.0 -> 1.5.1, 1.5.1 -> 1.6.0, …, 2.1.0 -> 2.2.0, 2.2.0 -> 2.3.0.

> 6. Run `roundup-admin -i <tracker_home> migrate` using the newer version of Roundup for the instance you are upgrading. This will update the database if it is required.

> 7. Bring your Roundup instance back online

> 8. Test

Repeat for each tracker instance.

Note

The v1.5.x releases of Roundup were the last to support Python v2.5 and v2.6. Starting with the v1.6 releases of Roundup Python version 2.7 that is newer than 2.7.2 is required to run Roundup. Starting with Roundup version 2.0.0 we also support Python 3 versions newer than 3.6. Roundup version 2.5 supports Python 3.7 and newer.

Recent release notes have the following labels:

- required - Roundup will not work properly if these steps are not done

- recommended - Roundup will still work, but these steps can cause security or stability issues if not done.

- optional - new features or changes to existing features you might want to use

- info - important possibly visible changes in how things operate

If you use virtual environments for your installation, you can run trackers with different versions of Roundup. So you can have one tracker using version 2.2.0 and another tracker using version 1.6.1. This allows you to upgrade trackers one at a time rather than having to upgrade all your trackers at once. Note that downgrading may require restoring your database to an earlier version, so make sure you backed up your database.

Note

This file only includes versions released in the last 10 years. If you are upgrading from an older version, start with the changes in the historical migration document.

Python 2 Support

If you are running Roundup under Python 2, you should make plans to switch to Python 3. Release 2.4.0 (Jul 2024) is the last release to officially support Python 2. The next non-patch release scheduled for 2025 will mark 5 years since Roundup supported Python 3.

XHTML Support Deprecation Notice

If you are running a tracker where the `html_version` setting in `config.ini` is `xhtml`, you should plan to change your templates to use html (HTML5). If you are affected by this, please send email to the roundup-users mailing list (roundup-users at lists.sourceforge.net). Version 2.3.0 is the last version to support XHTML.

## Migrating from 2.4.0 to 2.5.0

### XSS security issue with devel and responsive templates (recommended)

There are actually two different issues under this heading.

> 1. incorrect use of the `structure` keyword with `tal:content`

> 2. use of `tal:replace` on unsafe input

See the security page for a link to CVE-2025-53865.

In the discussion below, the html directory means one or more directories listed in the `templates` key of your tracker’s `config.ini` file.

These directions can be used to solve the XSS security issue with any version of Roundup. Even if you used a classic or minimal template, you should check your trackers for these issues. The classic template fixed most of these many years ago, but the updates were not made to the devel and responsive templates. No report of similar issues with the jinja template has been seen.

#### Incorrect use of structure in templates

The devel and responsive templates prior to Roundup 2.5 used this construct:

    tal:content="structure context/MUMBLE/plain"

Where `MUMBLE` is a property of your issues (e.g. title).

This construct allows a URL with a carefully crafted query parameter to execute arbitrary JavaScript.

You should check all your trackers. The classic template has not used this construct since at least 2009, but your tracker’s templates may use the offending construct anyway.

This fix will apply if your tracker is based on the responsive or devel template. Check the TEMPLATE-INFO.txt file in your tracker home. The template name is the first component of the `Name` field. For example a Name like:

    Name: responsive-bugtracker

    Name: devel-bugtracker

shows that tracker is based on the responsive or devel templates.

To fix this, remove the `structure` declaration when it is used with a plain representation. So fixing the code by replacing the example above with:

    tal:content="context/MUMBLE/plain"

prevents the attack.

To check for this issue, search for `structure` followed by `/plain` in all your html templates. If you are on a Linux/Unix system you can search the html subdirectory of your tracker with the following:

    grep 'structure.*/plain' *.html

which should return any lines with issues.

Warning

Backup the files in the `html` subdirectory of your tracker in case an edit goes wrong.

As an example, you could fix this issue using the GNU sed command:

    sed -i.bak -e '/structure.*\/plain/s/structure.//' *.html

to edit the files in place and remove the structure keyword. It will create a `.bak` file with the original contents of the file. If your templates were changed, this might still miss some entries. If you are on windows, some text editors support search and replace using a regular expression.

If the construct is split across lines:

    tal:content="structure
             context/MUMBLE/plain"

the commands above will miss the construct. So you should also search the html files using `grep /plain *.html` and verify that all of the `context/MUMBLE/plain` include `tal:content` as in the fixed example above. Any lines that have `context/MUMBLE/plain` without `tal:content=` before it need to be manually verified/fixed.

The distributed devel and responsive templates do not split the construct across lines, but if you changed the files it may be split.

#### tal:replace used with unsafe input

The problem was caused by the following markup:

    <span tal:replace="context/MUMBLE" />

in the head of the `bug.item.html`, `task.item.html` and other files in the devel and responsive templates.

This was fixed many years ago in the classic template’s `index.item.html`. The classic template replaces the above construct with:

    <tal:x tal:content="context/MUMBLE" />

`tal:content` explicitly escapes the result unless the `structure` directive is used. `tal:replace` expects the result to be safe and usable in an HTML context.

TAL drops any tags that it doesn’t know about from the output. `<tal:x tal:content="..." />` results in the value of the content expression without a surrounding html tag. (Effectively replacing the construct.)

The following diff for `bug.item.html` in the devel template shows the change to make things safe (remove lines starting with `-` and add lines staring with `+`):

     <tal:block metal:use-macro="templates/page/macros/frame">
     <title metal:fill-slot="head_title">
     <tal:block condition="context/id" i18n:translate=""
    - >Bug <span tal:replace="context/id" i18n:name="id"
    - />: <span tal:replace="context/title" i18n:name="title"
    - /> - <span tal:replace="config/TRACKER_NAME" i18n:name="tracker"
    + >Bug <tal:x tal:content="context/id" i18n:name="id"
    + />: <tal:x tal:content="context/title" i18n:name="title"
    + /> - <tal:x tal:content="config/TRACKER_NAME" i18n:name="tracker"
     /></tal:block>
     <tal:block condition="not:context/id" i18n:translate=""
      >New Bug report - <span tal:replace="config/TRACKER_NAME" i18n:name="tracker"

A similar change was applied in the following html files in the devel or responsive templates:

- _generic.collision.html

- bug.item.html

- keyword.item.html

- milestone.item.html

- msg.item.html

- task.item.html

- user.item.html

Also `page.html` should be changed from:

    <p class="label"><b tal:replace="request/user/username">username</b></p>

to:

    <p class="label"><b tal:replace="python:request.user.username.plain(escape=1)">username</b></p>

The code audit found the `tal:replace` construct is used with `context/id` and `context/designator` paths. The references to these paths have been changed to use `tal:x` in the classic template’s `msg.item.html` file and the classic and minimal template’s `_generic.collision.html` file.

These paths are critical to navigation in Roundup and are set from the path part of the URL. Roundup’s URL path validation makes it unlikely that an attacker could exploit them. If you wish you can change your templates or copy the corresponding files from the template if you haven’t made local changes.

Also you may have used copies of these insecure templates elsewhere in your tracker (e.g. to create a feature class). To find other possible issues you can use the command:

    grep -r "tal:replace=" *.html

in your tracker’s html directory. Check each occurrence and if needed, change it to the safer form. You should consider any reference to `context` to be under the user’s (attacker’s) control. Also `db` (excluding `db/config`) and `request` references that use user supplied content (e.g. `request/user/username` above) should be changed to `tal:x` form

### Deprecation Notices (required)

> - Support for SQLite version 2 has been removed in 2.5.0.

> - Support for the PySQLite library has been removed in 2.5.0. Only the Python supplied sqlite3 library is supported.

> - Roundup 2.5.0 supports Python 3.7 or newer. (It is not tested on Python 3.6. It may work but we don’t support it.)

### Update responsive template _generic.404.html and query.item.html (recommended)

This only applies if your tracker is based on the responsive template. Check the TEMPLATE-INFO.txt file in your tracker home. The template name is the first component of the `Name` field. For example a Name like:

    Name: responsive-bugtracker

is based on the responsive template. If the Name doesn’t start with `responsive` no changes are needed.

The `_generic.404.html` and `query.item.html` templates will crash when displayed because a missing macro is called. Change:

    <tal:block metal:use-macro="templates/page/macros/icing">

to:

    <tal:block metal:use-macro="templates/page/macros/frame">

at the top of both files. The icing macro used in other tracker templates was renamed to frame in this tracker template.

### Update userauditor.py detector (recommended)

When using the REST interface, setting the address property of the user to the same value it currently has resulted in an error.

If you have not changed your userauditor, you can copy one from any of the supplied templates in the `detectors/userauditor.py` file. Use `roundup-admin templates` to find a list of template directories.

If you have changed your userauditor from the stock version, apply the following diff:

                 raise ValueError('Email address syntax is invalid
                 "%s"'%address)

             check_main = db.user.stringFind(address=address)
    +        # allow user to set same address via rest
    +        if check_main:
    +            check_main = nodeid not in check_main
    +
           # make sure none of the alts are owned by anyone other than us (x!=nodeid)

add the lines marked with `+` in the file in the location after check_main is assigned.

### Modify config.ini password_pbkdf2_default_rounds setting (recommended)

The method for hashing and storing passwords has been updated to use PBKDF2 with SHA512 hash. This change was first introduced in Roundup 2.3 and is now the standard. If you previously added code in interfaces.py for a PBKDF2 upgrade to enable PBKDF2S5, you can remove that code now.

SHA512 is a more secure hash, it requires fewer rounds to ensure safety. The older PBKDF2-SHA1 needed around 2 million rounds.

You should update the `password_pbkdf2_default_rounds` setting in `config.ini` to 250000. This value is higher than the OWASP recommendation of 210000 from three years ago. If you don’t make this change, logins will be slow, especially for REST or XMLRPC calls.

See PBKDF2 upgrade for details on how to test the algorithm’s speed. We do not recommend reverting to the older SHA1 PBKDF2. If you have to do so due to a slow CPU, you can add the following to your tracker’s `interfaces.py`:

    from roundup.password import Password
    ## Use PBDKF2 (PBKDF2-SHA1) as default hash for passwords.
    # That scheme is at the start of the deprecated_schemes list and ha
    # to be removed.
    Password.default_scheme = Password.deprecated_schemes.pop(0)
    # Add PBKDF2S5 (PBKDF2-SHA512) as a valid scheme. Passwords
    # using it will be rehashed to use PBDKF2.
    Password.experimental_schemes.insert(0, "PBKDF2S5")

If you proceed with this, you should set `password_pbkdf2_default_rounds` to 2 million or more rounds to keep your hashed password database secure in case it gets stolen.

### Defusedxml support improves XMLRPC security (optional)

This release adds support for the defusedxml module. If it is installed it will be automatically used. The default xmlrpc module in the standard library has known issues when parsing crafted XML. It can take a lot of CPU time and consume large amounts of memory with small payloads.

When the XMLRPC endpoint is used without defusedxml, it will log a warning to the log file. The log entry can be disabled by adding:

    from roundup.cgi import client
    client.WARN_FOR_MISSING_DEFUSEDXML = False

to the `interfaces.py` file in the tracker home. (Create the file if it is missing.)

XMLRPC access is enabled by default in the classic and other trackers. Upgrading to defusedxml is considered optional because the XMLRPC endpoint can be disabled in the tracker’s `config.ini`. Also `Xmlrpc Access` can be removed from the `Users` role by commenting out a line in `schema.py`.

If you have enabled the xmlrpc endpoint, you should install defusedxml.

### Enable use of native date inputs (optional)

Roundup now can use native `date` or `datetime-local` inputs for `Date()` properties. These inputs take the place of the text input and calendar popup from earlier Roundup versions. Modern browsers come with a built-in calendar for date selection, so the `(cal)` calendar link is no longer needed. These native inputs show the date based on the browser’s locale and translate terms into the local language.

Note that the date format is tied to the language setting in most browsers, with some browsers you need special configurations to make the browser use the operating system date format.

By default the old input mechanism (using type=text inputs) is used. To enable native date input you need to set the config variable

    use_browser_date_input = yes

in section `[web]` in the `config.ini` file.

If native date input is used, simple uses of the `field()` method will generate `datetime-local` inputs to allow selection of a date and time. Input fields for `Date()` properties will not have the `(cal)` link anymore. If fields should only use a date (without time) you can specify the parameter `display_time=no` in `schema.py` for a `Date()` property (the default is `yes`). This will use `date` inputs in the generated html to select a date only. If you need this only for a single date, the `field()` method now has a boolean parameter `display_time` (which by default is set to the `display_time` parameter of `Date()`)

Complex uses using a `format` specification in `field()` will not be upgraded and will operate like earlier Roundup versions. In addition the `format` can now also be specified in the `Date()` constructor.

To upgrade all date properties, there are five changes to make:

> 1. Configure `use_browser_date_input = yes` in section `[web]` in `config.ini`

> 2. Optionally add `display_time = no` in the schema for Date() properties that should have no time displayed

> 3. Remove the format argument from field() calls on Date() properties.

> 4. Remove popcal() calls.

> 5. Include datecopy.js in page.html.

#### The `display_time` option

Both the `Date()` constructor and the `field` call take a `display_time` option which by default is `yes` in the `Date()` constructor and `True` in `field`. The `display_time` setting of `Date()` is inherited by the html property, so it doesn’t need to be specified in each `field()` call for this property.

When `display_time` is off, the date field does not include hours, minutes or seconds.

#### Remove format argument

Speaking of arguments, avoid setting the date `format` if you want to use native date inputs. If you include the format argument in the field method, it should be removed.

By default using a format argument will show the popup calendar link. You can disable the link by setting `popcal=False` in the field() call. If you have:

    tal:content="structure python:context.duedate.field(
                 placeholder='YYYY-MM, format='%Y-%m')"

changing it to:

    tal:content="structure python:context.duedate.field(
                 placeholder='YYYY-MM, format='%Y-%m',
                 popcal=False)"

will generate the input as in Roundup 2.4 or earlier without a popcal link.

#### Remove popcal

if you have enabled date input types in the configuration and you use the `popcal()` method directly in your templates, you should remove them. The browser’s native date selection calendar should be used instead.

#### Add copy/paste/edit on double-click using datecopy.js

When using date input types, there is no way to copy/paste using a native `datetime-local` or `date` input. With the `datecopy.js` file installed, double-clicking on the input turns it into a normal text input with the ability to copy, paste, or manually edit the date.

To set this up, take either `datecopy.js` or the smaller version, `datecopy.min.js`, from the `html` folder of the classic tracker template. Put the file in the `html` folder of your tracker home.

After you install the datecopy file, you can add the script directly to a page using:

    <script tal:attributes="nonce request/client/client_nonce"
            tal:content="structure python:utils.readfile('datecopy.min.js')">
    </script>

or get the file in a separate download using a regular script tag:

    <script type="text/javascript" src="@@file/datecopy.js">
    </script>

You can place these at the end of `page.html` just before the close body `</body>` tag. This is the method used in the classic template. This forces the file to be run for every page even those that don’t have any date inputs. However, it is cached after the first download.

Alternatively you can inline or link to it using a script tag only on pages that will have a date input. For example `issue.item.html`.

There is no support for activating text mode using the keyboard. Tablet/touch support is mixed. Chrome supports double-tap to activate text mode input. Firefox does not.

### Enable native number inputs for Number() and Integer() (optional)

Roundup’s `field()` method for properties of type `Number()` or `Integer()` can use a native browser number input by default.

This is configurable for all `Number()` and `Integer()` properties with the config option `use_browser_number_input` in section `[web]`.

You can use the old style text inputs for individual fields by calling the field method with `type="text"`.

Note that the `Integer()` type also uses `step="1"` by default to add a stepper control and try to constrain the input to integers. This can be overridden by passing a new step (e.g. `step="50"`) to the `field()` method.

This is an experiment and maybe changed based on feedback.

### Change in REST response for invalid CORS requests (info)

CORS preflight requests that are missing required headers can now result in either a 403 or 400 error code. If you permit anonymous users to access the REST interface, a 400 error may still occur. Previously, only a 400 error was given. This change is not expected to create issues since the client will recognize both codes it as an error response, and the CORS request will still fail.

### More secure session cookie handling (info)

This affects you if you are accessing a tracker via https. The name for the cookie that you get when logging into the web interface has a new name. When upgrading to Roundup 2.5 all users will have to to log in again. The cookie now has a `__Secure-` prefix to prevent it from being exposed/used over http.

If your tracker is using the unencrypted http protocol, nothing has changed.

See https://developer.mozilla.org/en-US/docs/Web/HTTP/Cookies#cookie_prefixes for details on this security measure.

### Invalid accept header now prevents operation (info)

In earlier versions, the rest interface checked for an incorrect “Accept” header, “@apiver”, or the “.json” mime type only after processing the request. This would lead to a 406 error, but the requested change would still be completed.

In this release, the validation of the output format and version occurs before any database changes are made. Now, all errors related to the data format (mime type, API version) will return 406 errors, where some previously resulted in 400 errors.

### New method for registering templating utils (info)

If you are building a template utility function that needs access to:

> - the database

> - the client instance

> - the form the user submitted

you had to pass these objects from the template using the `db`, `request.client` or `request.form` arguments.

A new method for registering a template utility has been added. If you use the `instance` object’s `registerUtilMethod()` to register a utility function, you do not need to pass these arguments. The function is called as a method and the first argument is a TemplatingUtils (tu) instance from which the client object (tu.client), the database (tu.client.db), form (tu.client.form), request (tu.client.request), the translator for the current language (tu._) and any functions (tu.X) you registered using `registerUtil()` are available.

You can find an example in Dynamic CSP.

### Directions for installing gpg (optional)

In this release a new version of the gpg module was needed for Ubuntu 24.04 and python 3.13. Paul Schwabauer produced a new version of the gpg module. However it is only on the test instance of pypi. If you run into issues installing gpg with pip, you can use:

    pip install --index-url https://test.pypi.org/simple/ \
                --extra-index-url https://pypi.org/simple gpg;

to installed version 2.0 of gpg from test.pypi.org obtaining it’s requirements from pypi.org.

When issue2551368 is closed, you should be able to use `pip install gpg` again.

## Migrating from 2.3.0 to 2.4.0

### Update your `config.ini` (required)

Upgrade tracker’s config.ini file. Use:

    roundup-admin -i /path/to/tracker updateconfig newconfig.ini

to generate a new ini file preserving all your settings. You can then merge any local comments from the tracker’s `config.ini` to `newconfig.ini` and replace `config.ini` with `newconfig.ini`.

`updateconfig` will tell you if it is changing old default values or if a value must be changed manually.

This will insert the bad API login rate limiting settings.

Also if you have `html_version` set to `xhtml`, you will get an error.

### Fix for CVE-2024-39124 in help/calendar popups (recommended)

Classhelper components accessed via URL using `@template=help`, `@template=calendar` or other template frame in the classhelper can run JavaScript embedded in the URL. If user clicks on a malicious URL that:

> - arrives in an email,

> - is embedded in a note left on a ticket [1],

> - left on some other web page

the JavaScript code will be executed. This vulnerability seems to be limited to manually crafted URL’s. It has not been generated by using Roundup’s mechanism for generating classhelper URLs.

The files that need to be changed to fix this depend on the template used to create the tracker. Check the TEMPLATE-INFO.txt file in your tracker home. The template name is the first component of the `Name` field. For example trackers with Names like:

    Name: classic-bugtracker

    Name: devel-mytracker

were derived from the `classic` and `devel` templates respectively. If your tracker is derived from the jinja2 template, you may not be affected as it doesn’t provide classhelpers by default. If you aren’t sure which tracker template was used to create your tracker home, check the `html/help.html` file for the word `Javascript`. If your help.html is missing the word `Javascript`, follow the directions for the classic template.

If you have not modified the original tracker html templates, you can copy replacement files from the new templates supplied with release 2.4.0. If you install 2.4.0 in a new virtual environment, you can use the command `roundup-admin templates` to find the installation path of the default templates.

If your template was based on the classic template, replace the following files in your tracker:

> - html/_generic.calendar.html

> - html/_generic.help-list.html

> - html/_generic.help-submit.html

> - html/_generic.help.html

> - html/user.help-search.html

> - html/user.help.html

If your template was based on the minimal template, replace the following files in your tracker:

> - html/_generic.calendar.html

> - html/_generic.help.html

If your template was based on the responsive or devel templates, replace the following files in your tracker:

> - html/_generic.calendar.html

> - html/_generic.help-submit.html

> - html/help.html

> - html/user.help-search.html

> - html/user.help.html

As an example, assume Roundup’s virtual environment is `/tools/roundup`. The classic tracker’s default template will be in `/tools/roundup/share/roundup/templates/classic`. Copy `/tools/roundup/share/roundup/templates/classic/html/_generic.calendar.html` to `html/_generic.calendar.html` in your tracker’s home directory. Repeat for every one of the files that needs to be replaced.

If you have made local changes to your popup/classhelper files or have created new help templates based on the existing ones, don’t copy the default files. Instead, follow the directions below to modify each file as needed for your template.

In the examples below, your script tag may differ. For example it could include:

    tal:attributes="nonce request/client/client_nonce"

If it does, keep the differences. You want to make changes to remove the structure option but keep the rest of the valid attributes.

Most files have a small script that sets a few variables from the settings in the URL. You should change:

    <script language="Javascript" type="text/javascript"
        tal:content="structure string:
        // this is the name of the field in the original form that we're working on
        form  = window.opener.document.${request/form/form/value};
        field  = '${request/form/property/value}';">

to:

    <script language="Javascript" type="text/javascript"
        tal:content="string:
        // this is the name of the field in the original form that we're working on
        form  = window.opener.document.${request/form/form/value};
        field  = '${request/form/property/value}';">

by removing the `structure` keyword from the tal:content block. This will html escape the settings in the URL. This neutralizes an attempt to execute JavaScript by manipulating the URL. Most of the files use code similar to this.

A few files have more extensive JavaScript embedded in the same script tag. To handle this you should split it into two scripts and encode the replaced strings. For example, change:

        <script language="Javascript" type="text/javascript"
            tal:content="structure string:<!--
    // this is the name of the field in the original form that we're working on
    form  = parent.opener.document.${request/form/form/value};
    callingform=form
    field  = '${request/form/property/value}';
    var listform = null
    function listPresent() {
      return document.frm_help.cb_listpresent.checked
    [more code skipped]

to:

        <script language="Javascript" type="text/javascript"
            tal:content="string:
    // this is the name of the field in the original form that we're working on
    form  = parent.opener.document.${request/form/form/value};
    callingform=form
    field  = '${request/form/property/value}';">
      </script>
      <script language="Javascript" type="text/javascript"
              tal:content="string:
    var listform = null
    function listPresent() {
      return document.frm_help.cb_listpresent.checked
    [...]

modifying the original by:

> 1. removing the `structure` keyword and the HTML comment marker `<!--`. This encodes the replaced strings.

> 2. adding `">` at the end of the line that sets `field` closes the script tag.

> 3. adding:

>        </script>

>              tal:content="string:

>    after the line used in step 2, to ends the first script and starts a new script.

Just removing the `structure` directive is enough to fix the bug. Splitting the large script into two parts:

> 1. one that has replaced strings with values taken from the URL

> 2. one that has no replaced strings

allows use of `structure` on the script with no replaced strings should it be required for your tracker.

[1]

If you are using markdown formatting for your tracker’s notes, the user will see the markdown label rather than the long (suspicious) URL. You may want to add something like:

    a[href*=\@template]::after {
        content: ' [' attr(href) ']';
    }

to your css. This displays the URL inside square brackets if the href has `@template` in it. It is placed after the link label.

### Fix CVE in earlier versions of Roundup (recommended)

If you are upgrading to version 2.4.0, you can skip this section. These fixes are already present in 2.4.0.

This section is for people who can not upgrade yet, and want to fix the issues.

#### Referer value not escaped CVE-2024-39125

Malicious JavaScript inserted into a page can change the value of the Referer header to include a script. If a link on that page points to a Roundup tracker, that script will be executed. The technique to change the header will result in a change of the URL in the browser’s address bar, but this is easily missed.

Fix this by editing `cgi/client.py`, and change:

    except (UsageError, Unauthorised) as msg:
       csrf_ok = False
       self.form_wins = True
       self._error_message = msg.args

to:

    except (UsageError, Unauthorised) as msg:
        csrf_ok = False
        self.form_wins = True
        self.add_error_message(' '.join(msg.args))

This escapes the Referer value and prevents it from being executed.

#### Stop JavaScript execution from attached files CVE-2024-39126

If an SVG, XML or PDF file that includes malicious JavaScript is attached to an issue, downloading the file will cause the JavaScript to run.

In `cgi/client.py` add the Content-Security-Policy line after the existing `nosniff` line so it looks like:

    # exception handlers.
    self.determine_language()
    self.db.i18n = self.translator
    self.setHeader("X-Content-Type-Options", "nosniff")
    self.setHeader("Content-Security-Policy", "script-src 'none'")
    self.serve_file(designator)

(the example is reindented for display).

This should prevent SVG and XML files with embedded scripts from running.

If your version of Roundup is old enough that the `nosniff` line is missing, search for `serve_file(designator)` and add both setHeader lines.

Warning

If your users use older browsers that don’t support Content Security Policies (e.g. Internet Explorer), you must remove `text/xml` and `image/svg` from `mime_type_allowlist` as explained below for `application/pdf`.

PDF files can also embed JavaScript. Many browsers include PDF viewers that may not support disabling scripting. The safest way to handle this is to force a download of the PDF file and use a PDF viewer with scripting disabled. To force downloading, look in `cgi/client.py` for `mime_type_allowlist` and remove the line for `application/pdf`.

Version 2.4.0 allows you to modify the mime_type_allowlist using interfaces.py. This will allow you to enable in-browser reading of PDF files when you upgrade to 2.4.0 if you wish.

Note that a Content Security Policy as documented in the admin guide is not applied it to a direct download. This requires adding an explicit CSP header as above.

### XHTML no longer supported (required)

If your `config.ini` sets `html_version` to `xhtml`, you need to change it to `html`. Then you need to change your tracker’s templates to html from xhtml.

Note that the default Roundup templates use html4 so it is unlikely that your templates are xhtml based. See issue2551323 for details on the deprecation of xhtml.

### Update MySQL character set/collations (required)

issue2551282 and issue2551115 discuss issues with MySQL’s utf8 support. MySQL has variations on utf8 character support. This version of Roundup expects to use utf8mb4 which is a version of utf8 that covers all characters, not just the ones in the basic multilingual plane. Previous versions of Roundup used latin1 or utf8mb3 (also known as just utf8). Newer versions of MySQL are supposed to make utf8mb4 and not utf8mb3 the default.

To convert your database, you need to have MySQL 8.0.11 or newer (April 2018) and a mysql client.

Warning

This conversion can damage your database. Back up your database using mysqldump or other tools. Preferably on a quiet database. Verify that your database can be restored (or at least look up directions for restoring it). This is very important.

We suggest shutting down Roundup’s interfaces:

> - web

> - email

> - cron jobs that use Python or roundup-admin

then make your backup.

Then connect to your mysql instance using `mysql` with the information in `config.ini`. If your tracker’s `config.ini` includes:

    name = roundupdb
    host = localhost
    user = roundupuser
    password = rounduppw

you would run some version of:

    mysql -u roundupuser --host localhost -p roundupdb

and supply `rounduppw` when prompted.

With the Roundup database quiet, convert the character set for the database and then for all the tables. To convert the tables you need a list of them. To get this run:

    mysql -sN -u roundupuser --host localhost -p \
       -e 'show tables;' roundupdb > /tmp/tracker.tables

The `-sN` removes line drawing characters and column headers from the output. For each table `<t>` in the file, run:

    ALTER TABLE `<t>` CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

You can automate this conversion using sed:

    sed -e 's/^/ALTER TABLE `/' \
     -e 's/$/` CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;/'\
     /tmp/tracker.tables> /tmp/tracker.tables.sql

The backticks “`” are required as some of the table names became MySQL reserved words during Roundup’s lifetime.

Inspect `tracker.tables.sql` to see if all the lines look correct. If so then we can start the conversion.

First convert the character set for the database by running:

    mysql -u roundupuser --host localhost -p roundupdb

Then at the `mysql>` prompt run:

    ALTER DATABASE roundupdb CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

you should see: `Query OK, 1 row affected (0.01 sec)`.

Now to modify all the tables run:

> . /tmp/tracker.tables.sql

You will see output similar to:

    Query OK, 5 rows affected (0.01 sec)
    Records: 5  Duplicates: 0  Warnings: 0

for each table. The rows/records will depend on the number of entries in the table. This can take a while.

Once you have successfully completed this, copy your tracker’s config.ini to a backup file. Edit `config.ini` to use the defaults:

> - mysql_charset = utf8mb4

> - mysql_collation = utf8mb4_unicode_ci

> - mysql_binary_collation = utf8mb4_0900_bin

Also look for a `~/.my.cnf` for the roundup user and make sure that the settings for character set (charset) are utf8mb4 compatible.

To test, run `roundup-admin -i tracker_home` and display an issue designator: e.g. `display issue10`. Check that the text fields are properly displayed (e.g. title). Start the web interface and browse some issues. Again, check that the text fields display correctly, that the history at the bottom of the issues displays correctly and if you are using the default full text search, make sure that that works.

If this works, bring email cron jobs etc. back online.

If this fails, take down the web interface, restore the database from backup, restore the old config.ini. Then test again and reach out to the mailing list for help.

We can use assistance in getting these directions corrected or enhanced. The core Roundup developers don’t use MySQL for their production workloads so we count on users to help us with this.

### Disable spellcheck on all password fields (recommended)

All tracker templates have been updated to disable spell checking on password input fields. This can help prevent exposing the password to an external server that provides spell checking for a browser. Since passwords should not be real words in any language, spell checking serves no purpose.

If you have modified your template with a “show password” option you should disable spell check.

To implement this in your deployed trackers, add:

    spellcheck="false"

to make your password inputs look like:

    <input type="password" spellcheck="false" name=....>

The changed files in the classic/devel/responsive templates are:

    html/page.html
    html/user.item.html

and in the jinja2 template the following files were changed:

    html/user.item.html
    html/user.register.html
    html/layout/navigation.html

### Add new classhelper to your templates (optional)

The classic classhelper invoked by the `(list)` link in your issue.item.html template can be greatly improved by wrapping the links with the new web-component based `roundup-classhelper`.

The new classhelper:

> - allows you to select items from multiple pages

> - is usable with a content security policy

> - is more easily styled

To deploy it, install the required files and wrap classhelp calls in the new `<roundup-classhelper>` component. For example, wrap:

    <span tal:condition="context/is_edit_ok" tal:replace="structure
       python:db.user.classhelp('username,realname,address',
       property='nosy', width='600'" />

so it looks like:

    <roundup-classhelper
      data-search-with="username,phone,roles[]">

      <span tal:condition="context/is_edit_ok" tal:replace="structure
         python:db.user.classhelp('username,realname,address',
         property='nosy', width='600')" />

    </roundup-classhelper>

to allow the user to search by: username, phone number and use a select/dropdown to search by role. Full details about the attributes and installation instructions can be found in the classhelper documentation in the admin guide.

### Disable performance improvement for wsgi mode (optional)

In Roundup version 2.2.0, an experimental feature was introduced to enhance performance while operating in wsgi mode. Initially, this feature was disabled. Over the past two years, it has been used at a few sites without any reported problems.

As a result, the default setting now enables this performance improvement, encouraging a wider adoption of the feature. In the event that an undiscovered bug arises, it can still be disabled if you experience problems. To disable it, modify your wsgi startup script and add the feature_flags to the RequestDispatcher as below:

    feature_flags = { "cache_tracker": False }
    app =  RequestDispatcher(tracker_home, feature_flags=feature_flags)

Then restart your wsgi instance. If you have to disable this feature, send email to the roundup-users mailing list (roundup-users at lists.sourceforge.net) so we can help you diagnose the cause and fix it for everybody.

In the future, support for disabling this improvement will be removed.

### Fix duplicate id for confirm password in user.item.html (optional)

The TAL macro `user_confirm_input` at the end of `html/page.html` for all templates except `jinja2` sets the `id` of the `Confirm password` input the same as the `Login Password` input. This creates an HTML error. Two items must not have the same id.

However browsers ignore the error and things still work. If you were to use css or javascript to target the `password` id, it would not work as expected.

To fix this, change the line near the end of your tracker’s `html/page.html` from:

    tal:attributes="id name; name string:@confirm@$name; readonly not:edit_ok" value="">

to:

    tal:attributes="id string:confirm_$name; name string:@confirm@$name; readonly not:edit_ok" value="">

This will change the id to `confirm_password`.

### Merge changes from devel template task.index.html (optional)

The devel template’s `task.index.html` has some fields that are not defined in the schema. It looks like it was originally copied from the `bug.index.html`. If the task index is requested without specifying the columns/fields, the template will crash trying to display `severity` and other fields that don’t exist in the task schema.

In normal use, the left hand menu for tasks always specifies valid columns so you may not see this issue. However if you remove the `@columns` query parameter, you can see the error.

The removed columns are: severity, versions, keywords, dependencies.

It is also missing the `solves` field which is added to match the schema.

You can see the diff in the Sourceforge web interface.

### Make group headers span all columns (optional)

In a number of index pages a version of the following TAL command appears:

    <th tal:attributes="colspan python:len(request.columns)" class="group">

If the `@columns` parameter (aka request.columns) is not set, all columns are shown. However the group header only spans the first column. Changing this to read:

    <th tal:attributes="colspan python:len(request.columns) or 100" class="group">

makes the group header span all the columns (if you have fewer than 100 columns). All of the supplied templates hae been upgraded with this change. See issue 2551341 for details.

Note the jinja2 template has the same issue, but the development team hasn’t devised a solution.

### Use @current_user in Searches (optional)

You can create queries like: “My issues” by searching the `creator` property of issues for your id number. Similarly you can search for “Issues assigned to me” by searching on the `assignedto` property.

Queries in Roundup can be shared between users. However queries like these can be shared. However for any user but they will only find issues created by/assigned to the user who created the query.

This release allows you to search Links to the User class by specifying `@current_user`. This token searches for the currently log in user. It makes searches like the above usable when shared.

This only works for properties that are a Link to the user class. E.G. creator, actor, assignedto. It does not yet work for MultiLink properties (like nosy).

As an example this can be deployed to the classic tracker’s issue search template (issue.search.html), by replacing:

    <option metal:fill-slot="extra_options" i18n:translate=""
            tal:attributes="value request/user/id">created by
            me</option>

with:

    <option metal:fill-slot="extra_options" value="@current_user"
            tal:attributes="selected python:value == '@current_user'"
            i18n:translate="">created by me</option>

There are three places where `value request/user/id` is used in the classic template. Your template may have more.

If you have a user with the exact username of @current_user they should change it. Details can be found in issue1525113.

### New PostgreSQL Settings (optional)

With this release, you can specify a Postgresql database schema to use. By default Roundup creates a database when using `roundup-admin init`. Setting the rdbms `name` keyword to `roundup_database.roundup_schema` will create and use the `roundup_schema` in the pre-created `roundup_database`. See the Roundup PostgreSQL documentation for details on how to set up the roles.

Also there is a new configuration keyword in the rdbms section of `config.ini`. The `service` keyword allows you to define the service name for Postgres that will be looked up in the Connection Service File. Any of the methods of specifying the file including by using the `PGSERVICEFILE` environment variable are supported.

This is similar to the existing support for MySQL option/config files and groups.

If you use services, any settings for the same properties (user, name, password …) that are in the tracker’s `config.ini` will override the service settings. So you want to leave the `config.ini` settings blank. E.G.:

    [rdbms]
    name =
    host =
    port =
    user =
    password =
    service = roundup_roundup

Setting `service` to `roundup_roundup` with the following in the service file:

    [roundup_roundup]
    host=127.0.0.1
    port=5432
    user=roundup
    password=roundup
    dbname=roundup

would use the roundup database with the specified credentials. It is possible to define a service that connects to a specific schema using:

    options=-c search_path=roundup_service_dev

Note that the first schema specified after `search_path=` is created and populated. The schema name (`roundup_service_dev`) must be terminated by: a comma, whitespace or end of line.

You can use the command `psql "service=db_service_name"` to verify the settings in the connection file. Inside of `psql` you can verify the `search_path` using `show search_path;`.

### Update for user.help-search.html (optional)

There is a bug in the template used as a search helper for the user fields (e.g. the nosy list). The `properties` url query argument was ignored. You can not select the displayed fields using the `properties` argument. This is fixed in 2.4.0. You can probably just copy the `user.help-search.html` from the classic tracker template.

If you have modified that template, you can follow the analysis in issue2551320 to fix your template.

### Update for _generic.help.html (optional)

Using the `_generic.help.html` template with `classhelper()` to provide information on a property without selecting a property caused an error when processing the template. Using the help template with Link properties can provide description or other information that the user can use to determine the right setting.

If your tracker is based on the minimal or classic tracker and you have not changed the _generic.help.html file, you can copy it into place from the template directory.

### Fix static_files use of ‘-’ directory (info)

Use of the ‘-’ directory in `static_files` config.ini setting now works. So it will prevent access to the html directory when using `@@file/` based url’s.

### Bad Login Rate Limiting and Locking (info)

Brute force logins have been rate limited in the HTML web interface for a while. This was not the case with the API interfaces.

This release introduces rate limiting for invalid REST or XMLRPC API logins. As with the web interface, users who have hit the rate limit have their accounts locked until after the recommended delay time has passed. See information on configuring the API rate limits for details.

### Removal of cgi.py from Python (info)

The `cgi.py` module will be removed starting with Python 3.13. Roundup now vendors a copy of `cgi.py` and makes it and its storage objects available by importing from:

    from roundup.anypy.cgi_ import cgi
    from roundup.anypy.cgi_ import FieldStorage, MiniFieldStorage

It is unlikely that you will care unless you have done some expert level Roundup customization. If you have, use one of the imports above if you plan on running on Python 3.13 (expected in 2024) or newer.

### Fixing PostgreSQL Out of Memory Errors when Importing Tracker (info)

Importing a tracker into PostgreSQL can run out of memory with the error:

    psycopg2.errors.OutOfMemory: out of shared memory
    HINT:  You might need to increase max_locks_per_transaction.

before changing your PostgreSQL configuration, try changing the pragma `savepoint_limit` to a lower value. By default it is set to `10000`. In some cases this may be too high. See the administration guide for further details.

### roundup-admin’s History Command Produces Readable Output (info)

The history command of roundup-admin used to print the raw journal data. In this release the default is to produce more human readable data. The original output (not pretty printed as below) was:

    [('1', <Date 2013-02-18.20:30:34.125>, '1', 'create', {}),
    ('1',
     <Date 2013-02-19.21:24:20.391>,
     '1',
     'set',
     {'messages': (('+', ['3']),)}),
    ('1', <Date 2013-02-19.21:24:24.797>, '1', 'set', {'priority': '1'}),
    ('1',
     <Date 2013-02-20.03:16:52.000>,
     '1',
     'link',
     ('issue', '2', 'dependson')),
    ('1', <Date 2013-02-21.20:51:40.750>, '1', 'link', ('issue', '2',
    'seealso')),
    ('1',
     <Date 2013-02-22.05:33:08.875>,
     '1',
     'set',
     {'dependson': (('+', ['3']),), 'private': None, 'queue': None}),
    ('1',
     <Date 2013-02-22.05:33:19.406>,
     '1',
     'set',
     {'dependson': (('+', ['2']),)}),
    ('1',
     <Date 2013-02-27.03:24:42.844>,
     '1',
     'unlink',
     ('issue', '2', 'seealso')),
     ...

Now it produces (Each entry is on one line, lines wrapped and indented for display):

    admin(2013-02-18.20:30:34) create issue
    admin(2013-02-19.21:24:20) set modified messages: added: msg3
    admin(2013-02-19.21:24:24) set priority was critical(1)
    admin(2013-02-20.03:16:52) link added issue2 to dependson
    admin(2013-02-21.20:51:40) link added issue2 to seealso
    admin(2013-02-22.05:33:08) set modified dependson: added: issue3;
         private was None; queue was None
    admin(2013-02-22.05:33:19) set modified dependson: added: issue2
    admin(2013-02-27.03:24:42) unlink removed issue2 from seealso
    ...

A few things to note: set operations can either assign a property or report a modification of a multilink property. If an assignment occurs, the value reported is the old value that was there before the assignment. It is not the value that is assigned. In the example above I don’t know what the current value of priority is. All I know it was set to critical when the issue was created.

Modifications to multilink properties work differently. I know that `msg3` was present in the messages property after 2013-02-19 at 21:24:20 UTC.

The history command gets a new optional argument `raw` that produces the old style output. The old style is (marginally) more useful for script automation.

### Deprecation Notices (info)

Support for SQLite version 1 has been removed in 2.4.0.

Support for SQLite version 2 will be removed in 2.5.0.

Support for StructuredText has been removed in 2.4.0. Support for reStructuredText remains.

Support for the PySQLite library will be removed in 2.5.0. Only the Python supplied sqlite3 library will be supported.

## Migrating from 2.2.0 to 2.3.0

### Update your `config.ini` (required)

Upgrade tracker’s config.ini file. Use:

    roundup-admin -i /path/to/tracker updateconfig newconfig.ini

to generate a new ini file preserving all your settings. You can then merge any local comments from the tracker’s `config.ini` to `newconfig.ini` and replace `config.ini` with `newconfig.ini`.

`updateconfig` will tell you if it is changing old default values or if a value must be changed manually.

### Using the roundup-mailgw script (required)

In previous versions the roundup-mailgw script had a `-C` (or `--class`) option for specifying a class to be used with `-S` (or `--set`) option(s). In the latest version the `-C` option is gone, the class for this option is specified as a prefix, e.g. instead of

    roundup-mailgw -C issue -S issueprop=value

You now specify

    roundup-mailgw -S issue.issueprop=value

If multiple values need to be set, this can be achieved with multiple `-S` options or with delimiting multiple values with a semicolon (in that case the string needs to be quoted because semicolon is a shell special character):

    roundup-mailgw -S 'issue.issueprop1=value1;issueprop2=value2'
    roundup-mailgw -S issue.issueprop1=value1 -S issue.issueprop2=value2

are equivalent. Note that the class is provided as a prefix for the set-string, not for each property. The class can be omitted altogether in which case it defaults to `msg` (this default existed in previous versions).

If you do not use the `-C` (or `--class`) option in your current setup of mailgw you don’t need to change anything.

### Replace Create User permission for Anonymous with Register (required)

Check your trackers schema.py. If you have the following code:

    db.security.addPermissionToRole('Anonymous', 'Create', 'user')

after the permission for Anonymous ‘Email Access’, change it to:

    db.security.addPermissionToRole('Anonymous', 'Register', 'user')

The comment for Anonymous ‘Email Access’ may refer to Create. Change it to refer to Register.

This will be an issue if you used the devel or responsive tracker templates. If you used a classic, minimal or jinja2 template the permission change (but not the comment change) should be done already.

### Rdbms version change from 7 to 8 (required)

This release includes a change that requires updates to the database schema.

Sessions and one time key (otks) tables in the Mysql and PostgreSQL database use a numeric type that truncates/rounds expiration timestamps. This results in entries being purged early or late (depending on whether it rounds up or down). The discrepancy is a couple of days for Mysql or a couple of minutes for PostgreSQL.

Session keys stay for a week or more and CSRF keys are two weeks by default. As a result, this isn’t usually a visible issue. This migration updates the numeric types to ones that supports more significant figures.

You should backup your instance and run the `roundup-admin -i <tracker_home> migrate` command for all your trackers once you’ve installed the latest code base.

Do this before you use the web, command-line or mail interface and before any users access the tracker.

If successful, this command will respond with either “Tracker updated” (if you’ve not previously run it on an RDBMS backend) or “No migration action required” (if you have run it, or have used another interface to the tracker, or are using anydbm).

### Session/OTK data storage for SQLite backend changed (required)

Roundup stores a lot of ephemeral data:

- login session tokens,

- rate limits

- password reset attempt tokens

- one time keys

- and anti CSRF keys.

These were stored using dbm style files while the main data is stored in a SQLite db. Using both dbm and sqlite style files is surprising and due to how we lock dbm files can be a performance issue.

However you can continue to use the dbm files by setting the `backend` option in the `[sessiondb]` section of `config.ini` to `anydbm`.

If you do not change the setting, two sqlite databases called `db-otk` and `db-session` replace the dbm databases. Once you make the change the old `otks` and `sessions` dbm databases can be removed.

Note this replacement will require users to log in again and refresh web pages to save data. It is best if people save all their changes and log out of Roundup before the upgrade is done to minimize confusion. Because the data is ephemeral, there is no plan to migrate this data to the new SQLite databases. If you want to keep using the data set the `sessiondb` `backend` option as described above.

### Update `config.ini`’s `password_pbkdf2_default_rounds` (required)

Roundup hashes passwords using PBKDF2 with SHA1. In this release, you can upgrade to PBKDF2-SHA512 from current PBKDF2-SHA1 (recommended). If you upgrade, you want to set the default rounds according to the PBKDF2-SHA512 upgrading directions. Note that this algorithm is expected to be the default in a future version of Roundup.

If you don’t want to upgrade, we recommend that you increase the default number of rounds from the original 10000. PBKDF2 has a parameter that makes hashing a password more difficult to do. The original 10000 value was set years ago. It has not been updated for advancements in computing power.

This release of Roundup changes the value to 2000000 (2 million). This exceeds the current recommended setting of 1,300,000 for PBKDF2 when used with SHA1.

Caution

If you were using the old 10000 value, it will be automatically upgraded to 2 million by using `roundup-admin`’s `updateconfig`. If you were not using the old 10000 default, you should update it manually.

After the change users will still be able to log in using the older 10000 round hashed passwords. If `migrate_passwords` is set to `yes`, passwords will be automatically re-hashed using the new higher value when the user logs in. If `password_pbkdf2_default_rounds` is set to a lower value than was used to hash a password, the password will not be rehashed so the higher value will be kept. The lower value will be used only if the password is changed using the web or command line.

Increasing the number of rounds will slow down re-hashing. That’s the whole point. Sadly it will also slow down logins. Usually the hash takes under 1 second, but if you are using a slow chip (e.g. an ARM V6 at 700 bogo mips) it can take 30 seconds to compute the 2000000 rounds. The slowdown is linear. So what takes .001 seconds at 10000 rounds will take: `2000000/10000 * .001 = 200 * .001` seconds or 0.2 seconds.

You can see how long it will take by using the new `roundup-admin` `perftest` command. After you have finished migrating your database, run:

    roundup-admin -i <tracker_home> perftest password scheme=PBKDF2 rounds=10000

and then:

    roundup-admin -i <tracker_home> perftest password scheme=PBKDF2 rounds=2,000,000

so see the difference. Output from this command looks like:

    Hash time: 0.203151849s scheme: PBKDF2 rounds: 10000

If your testing reports a hash time above 0.5 seconds for 10000 rounds, there may be another issue. See if executing:

    python3 -c 'from hashlib import pbkdf2_hmac'

produces an error.

If you get an ImportError, you are using Roundup’s fallback PBKDF2 implementation. It is much slower than the library version. As a result re-encrypting the password (and logging in, which requires calculating the encrypted password) will be very slow.

You should find out how to make the import succeed. You may need to install an OS vendor package or some other library.

### Upgrade to PBKDF2-SHA512 from current PBKDF2-SHA1 (recommended)

We recommend that you upgrade to using PBKDF2-SHA512 for hashing your passwords. This is a more secure method than the old PBKDF2 (with SHA1). Because the algorithm is more secure, it uses a smaller value for `password_pbkdf2_default_rounds`. Setting `password_pbkdf2_default_rounds` to `250000` exceeds the current recommended setting of 210,000 iterations for PBKDF2 when used with SHA512.

You can see how long this takes to calculate on your hardware using `roundup-admin`’s perftest command. For example:

    roundup-admin -i <tracker_home> perftest password scheme=PBKDF2S5 rounds=250,000

produces:

    Hash time: 0.161892945 seconds, scheme: PBKDF2S5, rounds: 250000

Any increase in the number of rounds will cause the password to automatically be rehashed to the higher value the next time the user logs in via the web interface. Changing the number of rounds to a lower value will not trigger a rehash during login unless the scheme is also being changed. The lower number will be used only when the password is explicitly changed using the web interface or the command line (`roundup-admin` for example).

Change the default hashing scheme by adding the following lines to the `interfaces.py` file in your tracker home:

    from roundup.password import Password
    ## Use PBDKF2S5 (PBKDF2-SHA512) for passwords. Re-hash old PBDFK2
    # Force password with scheme PBKDF2 (SHA1) to get re-hashed
    Password.deprecated_schemes.insert(0, Password.known_schemes[0])
    # choose PBKDF2S5 as the scheme to use for rehashing.
    Password.default_scheme = Password.experimental_schemes[0]

You may need to create the `interfaces.py` file if it doesn’t exist. In the future, when the default hash is changed to PBKDF2S5, upgrade directions will include instructions to remove these lines and the file `interfaces.py` if it becomes empty.

You can verify that PBKDF2S5 is used by default by running:

    roundup-admin -i <tracker_home> perftest password rounds=250,000

and verify that the scheme is PBKDF2S5.

### jQuery updated with updates to user.help.html (recommended)

The devel and responsive templates shipped with an old version of jQuery. According to automated tests, it may have a security issue. It has been updated to the current version: 3.6.3. If your tracker is based on one of these templates (see the `TEMPLATE-INFO.txt` file in your tracker), remove the old `html/jquery.js` file from your tracker and copy the new `jquery-3.6.3.js` file from the template directory to your tracker’s `html` directory. Also copy in the new `user.help.html` file. It now references the new `jquery-3.6.3.js` file.

### Session/OTK data storage using Redis (optional)

You can store your ephemeral data in a Redis database. This provides significantly better performance for ephemeral data than SQLite or dbm files. See the section Using Redis for Session Databases in the administration guide

### New SQLite databases created with WAL mode journaling (optional)

By default, SQLite databases use a rollback journal when writing an update. The rollback journal stores a copy of the data from before the update. One downside of this is that all reads have to be suspended while a write is occurring. SQLite has an alternate way of insuring ACID compliance by using a WAL (write ahead log) journal.

Version 2.3.0 of Roundup, creates new SQLite databases using WAL journaling. With WAL, a writer does not block readers and readers do not block writing an update. This keeps Roundup accessible even under a heavy write load (e.g. when bulk loading data or automated updates via REST).

If you want to convert your existing SQLite db to WAL mode:

> 1. check the current journal mode on your database using:

>        sqlite3 <tracker_home>/db/db "pragma journal_mode;"

> 2. If it returns `delete`, change it to WAL mode using:

>        sqlite3 <tracker_home>/db/db "pragma journal_mode=WAL;"

> 3. verify by running the command in step 1 again and you should get `wal`.

If you are using SQLite for session and otk databases, perform the same steps replacing `db` with `db-session` and `db-otk`.

If you find WAL mode is not working for you, you can set the journal method to a rollback journal (`delete` mode) by using step 2 and replacing `wal` with `delete`. (Note: SQLite supports other journaling modes, but only `wal` and `delete` persist. Roundup doesn’t set a journaling mode when it opens the database, so journaling mode options such as `truncate` are not useful.)

For details on WAL mode see https://www.sqlite.org/wal.html and https://www.sqlite.org/pragma.html#pragma_journal_mode.

### Change in processing allowed_api_origins setting (info)

In this release you can use both `*` (as the first origin) and explicit origins in the `allowed_api_origins` setting in `config.ini`. (Before it was only one or the other.)

You do not need to use `*`. If you do, it allows any client anonymous (unauthenticated) access to the Roundup tracker. This is the same as browsing the tracker without logging in. If they try to provide credentials, access to the data will be denied by CORS.

If you include explicit origins (e.g. https://example.com), users from those origins will not be blocked if they use credentials to log in.

### Change in processing of In-Reply_to email header (info)

Messages received via email usually include a `[issue23]` designator in the subject line. This indicates what issue is being updated. If the designator is missing, Roundup tries to find the correct issue by using the in-reply-to email header.

The former code appends the new message to the first issue found with a message matching the in-reply-to header. Usually a message is associated with only one issue. However nothing in Roundup requires that.

In this release, the in-reply-to matching is disabled if there are multiple issues with the same message. In this case, subject matching is used to try to find the matching issue.

If you don’t have messages assigned to multiple issues you will see no change. If you do have multi-linked messages this will hopefully result in better message->issue matching.

### Incremental/batch full test reindexing with roundup-admin (info)

The `reindex` command in `roundup-admin` can reindex a range of items. For example:

    roundup-admin -i ... reindex issues:1-1000

will reindex only the first 1000 issues. This is useful since reindexing can take a while and slow down the tracker. By running it in batches you can control when the reindex runs rather than having to wait for it to complete all the reindexing. See the man page or administration guide for details.

## Migrating from 2.1.0 to 2.2.0

### Update your `config.ini` (required)

Upgrade tracker’s config.ini file. Use:

    roundup-admin -i /path/to/tracker updateconfig newconfig.ini

to generate a new ini file preserving all your settings. You can then merge any local comments from the tracker’s `config.ini` to `newconfig.ini` and replace `config.ini` with `newconfig.ini`.

### Rdbms version change from 6 to 7 (required)

This release includes two changes that require updates to the database schema:

> 1. The size of words included in the Roundup FTS indexers have been increased from 25 to 50. This requires changes to the database columns used by the native indexer. This also affect the whoosh and xapian indexers.

> 2. Some databases that include native full-text search (native-fts indexer) searching are now supported.

You should run the `roundup-admin -i <tracker_home> migrate` command for all your trackers once you’ve installed the latest codebase.

Do this before you use the web, command-line or mail interface and before any users access the tracker.

If successful, this command will respond with either “Tracker updated” (if you’ve not previously run it on an RDBMS backend) or “No migration action required” (if you have run it, or have used another interface to the tracker, or are using anydbm).

See below if you want to enable native-fts searching.

The increase in indexed word length also affects whoosh and xapian backends. You may want to run `roundup-admin -i tracker_home reindex` if you want to index or search for longer words in your full text searches. Re-indexing make take some time.

### Check new login_empty_passwords setting (required)

In this version of Roundup, users with a blank password are not allowed to login. Blank passwords have been allowed since 2002, but 2022 is a different time. If you have a use case that requires a user to login without a password, set the `login_empty_passwords` setting in the `web` section of `config.ini` to `yes`. In general this should be left at its default value of `no`.

### Verify that SQLite supports FTS5 (required)

If you use SQLite as your backend, it must support FTS5. See the FTS5 testing steps for how to verify this.

### Check allowed_api_origins setting (optional)

If you are using the REST or xmlrpc api’s from an origin that is different from your roundup tracker, you will need to add your allowed origins to the allowed_api_origins in your updated `config.ini`. Upgrade your `config.ini` as described above then read the documentation for the setting in `config.ini`.

### Check compression settings (optional)

Read the administration guide section on Configuring Compression.

Upgrade your tracker’s config.ini as described above. Compare the old and new files and configure new compression settings as you want. Then replace `config.ini` with the `newconfig.ini` file.

### Search added to user index page (optional)

A search form and count of number of hits has been added to the `user.index.html` template page in the classic template. You may want to merge the search form and footer into your template.

### Enhanced full-text search (optional)

SQLite’s FTS5 full-text search engine is available as is PostgreSQL’s full text search. Both require a schema upgrade so you should run:

    roundup-admin -i tracker_home migrate

to create FTS specific tables before restarting the roundup-web or email interfaces.

SQLite 3.9.0+ or PostgreSQL 11.0+ are required to use this feature. When using SQLite, all full text search fields will allow searching using the MATCH query format described at: https://www.sqlite.org/fts5.html#full_text_query_syntax. When using PostgreSQL either the websearch_to_tsquery or to_tsquery formats described on https://www.postgresql.org/docs/14/textsearch-controls.html#TEXTSEARCH-PARSING-QUERIES can be used. The default is websearch. Prefixing the search with `ts:` enables tsquery mode.

A list of words behaves almost the same as the default text search (`native`). So the search string `fts search` will find all issues that have both of those words (an AND search) in a text-field (like title) or in a message (or file) attached to the issue.

One thing to note is that native-fts searches do not ignore words longer than 50 characters or less than 2 characters. Also SQLite does not filter out common words (i.e. there is no stopword list). So words like “and”, “or”, “then”, “with” … are included in the FTS5 search.

You must explicitly enable this search mechanism by changing the `indexer` setting in `config.ini` to `native-fts`. Native-fts must be explicitly chosen. This is different from Xapian or Whoosh indexers, which are chosen if they are installed in the Python environment. This prevents the existing native indexing from being discarded if `indexer` is not set.

Next re-index your data with `roundup-admin -i tracker_home reindex`. This can take a while depending on the size of the tracker.

You may want to update your `config.ini` by following the directions above to get the latest documentation.

See the administration guide notes on native-fts for further details.

### Adding error reporting templates (optional)

Currently some internal errors result in a bare html page with an error message. The usual chrome supplied by page.html is not shown. For example query language syntax errors for full text search methods will display a bare HTML error page.

If you add an `_generic.400.html` template to the html directory, you can display the error inside of the layout provided by the `page.html` template. This can make fixing the error and navigation easier. You can use the `_generic.404.html` template to create a `_generic.400.html` by modifying the title and body text. You can test the 400 template by appending `@template=400` to the url for the tracker.

### Change passwords using crypt module (optional)

The crypt module is being removed from the standard library. Any stored password using crypt encoding will fail to verify once the crypt module is removed (expected in Python 3.13 see pep-0594). Automatic migration of passwords (if enabled in config.ini) re-encrypts old passwords using something other than crypt if a user logs in using the web interface.

You can find users with passwords still encrypted using crypt by running:

    roundup-admin -i <tracker_home> table password,id,username

Look for lines starting with `{CRYPT}`. You can reset the user’s password using:

    roundup-admin -i <tracker_home>
    roundup> set user16 password=somenewpassword

changing `16` to the id in the second column of the table output. The example uses interactive mode (indicated by the `roundup>` prompt). This prevents the new password from showing up in the output of ps or shell history. The new password will be encrypted using the default encryption method (usually pbkdf2).

### Enable performance improvement for wsgi mode (optional)

There is an experimental wsgi performance improvement mode that caches the loaded roundup instance. This eliminates disk reads that are incurred on each connection. In one report it improves speed by a factor of 2 to 3 times. To enable this you should add a feature flag to your Roundup wsgi wrapper (see the file `.../share/frontends/wsgi.py`) so it looks like:

    feature_flags = { "cache_tracker": "" }
    app =  RequestDispatcher(tracker_home, feature_flags=feature_flags)

to enable this mode. Note that this is experimental and was added during the 2.2.0 beta period, so it is enabled using a feature flag. If you use this and it works for you please followup with an email to the roundup-users at lists.sourceforge.net mailing list so we can enable it by default in a future release.

### Hide submit button during readonly use of _generic.item.html (optional)

The submit button in _generic.item.html always shows up even when the user doesn’t have edit perms. Change the `context/submit` html to read:

    <td colspan=3 tal:content="structure context/submit"
        tal:condition="context/is_edit_ok">

in your TAL based templates. The `jinja2` based templates are missing this file, but if you implemented one you want to surround the jinja2 code with:

    {% if context.is_edit_ok() %}
      <submit button code here>
    {% endif %}

## Migrating from 2.0.0 to 2.1.0

### Rdbms version change from 5 to 6 (required)

To fix an issue with importing databases, the database has to be upgraded for rdbms backends.

You should run the `roundup-admin migrate` command for your tracker once you’ve installed the latest codebase.

Do this before you use the web, command-line or mail interface and before any users access the tracker.

If successful, this command will respond with either “Tracker updated” (if you’ve not previously run it on an RDBMS backend) or “No migration action required” (if you have run it, or have used another interface to the tracker, or are using anydbm).

This only changes the schema for the mysql backend. It has no effect other than upgrading the revision on other rdbms backends.

On the mysql backend it creates the database index that makes sure the key field for your class is unique.

If your update/migration fails, you will see an:

    IntegrityError: (1062, "Duplicate entry '0-NULL' for key '_user_key_retired_idx'")

it means you have two non-retired members of the class with the same key field. E.G. two non-retired users with the same username.

Debug this using roundup-admin using the list command. For example dump the user class by the key field `username`:

    $ roundup-admin -i <tracker_home> list user username
      1: admin
      2: anonymous
      3: demo
      4: agent
      5: provisional
      6: foo@example.com
      7: dupe
      8: dupe
      ...

then search the usernames for duplicates. Once you have identified the duplicate username (`dupe` above), you should retire the other active duplicates or change the username for the duplicate. To retire `7: dupe`, you run:

    roundup-admin -i <tracker_home> retire user7

(use `restore user7` if you retired the wrong item). If you want to rename the entry use:

    roundup-admin -i <tracker_home> set user7 username=dupe1

Keep doing this until you have no more duplicates. Then run the update/migrate again.

If you have duplicate non-retired entries in your database, please email roundup-users at lists.sourceforge.net. We are interested in how many issues this has caused. Duplicate creation should occur only when two or more mysql processes run in parallel and both of them creating an item with the same key. So this should be a rare event. The internal duplicate prevention checks should work in other cases.

For the nerds: if you had a new installation that was created at version 5, the uniqueness of a key was not enforced at the database level. If you had a database that was at version 4 and then upgraded to version 5 you have the uniqueness enforcing constraint. Running migrate updates to schema version 6 and installs the unique index constraint if it is missing.

### Setuptools is now required to install (info)

Roundup install now uses setuptools rather than distutils. You must install setuptools. Use the version packgaged by your OS vendor. If your OS vendor doesn’t supply setuptools use `pip install setuptools`. (You may need pip3 rather than pip if using python3.)

### Define Authentication Header (optional)

The web server in front of roundup (apache, nginx) can perform user authentication. It can pass the authenticated username to the backend in a variable. By default roundup looks for the `REMOTE_USER` variable. This can be changed by setting the parameter `http_auth_header` in the `[web]` section of the tracker’s `config.ini` file to a different value. The value is case sensitive. If the value is unset (the default) the REMOTE_USER variable is used.

If you are running roundup using `roundup-server` behind a proxy that authenticates the user you need to configure `roundup-server` to pass the HTTP header with the authenticated username to the tracker. By default `roundup-server` looks for the `REMOTE_USER` header for the authenticated user. You can copy an arbitrary header variable to the tracker using the `-I` option to roundup-server (or the equivalent option in the roundup-server config file).

For example to use the `uid_variable` header, two configuration changes are needed: First configure `roundup-server` to pass the header to the tracker using:

    roundup-server -I uid_variable ....

note that the header is passed exactly as supplied by the upstream server. It is not prefixed with `HTTP_` like other headers since you are explicitly allowing the header. Multiple comma separated headers can be passed to the `-I` option. These could be used in a detector or other tracker extensions, but only one header can be used by the tracker as an authentication header.

To make the tracker honor the new variable changing the tracker `config.ini` to read:

    [web]
    ...
    http_auth_header = uid_variable

At the time this is written, support is experimental. If you use it you should notify the roundup maintainers using the roundup-users at lists.sourceforge.net mailing list.

### Classname Format Enforced (info)

Check schema.py and look at all Class(), IssueClass(), FileClass() calls. The second argument is the classname. All classnames must:

> - start with an alphabetic character

> - consist of alphanumerics and ‘_’

> - not end with a digit

this was not enforced before. Using non-standard classnames could lead to other issues.

### jQuery updated with updates to user.help.html (recommended)

The devel and responsive templates shipped with an old version of jQuery with some security issues. It has been updated to the current version: 3.5.1. If your tracker is based on one of these templates (see the `TEMPLATE-INFO.txt` file in your tracker), remove the old `html/jquery.js` file from your tracker and copy the new `jquery-3.5.1.js` file from the template directory to your tracker’s `html` directory. Also copy in the new `user.help.html` file. It now references the new `jquery-3.5.1.js` file and also fixes a bug that prevented applying the change from the helper to the field on the main form.

### Roundup-admin security stops on incorrect properties (info)

The `roundup-admin ... security` command used to continue running through the rest of the security roles after reporting a property error. Now it stops after reporting the incorrect property.

If run non-interactively, it exits with status 1. It can now be used in a startup script to detect permission errors.

### Futureproof devel and responsive timezone selection extension (recommended)

The devel and responsive (derived from devel) templates use a select control to list all available timezones when pytz is used. It sanitizes the data using cgi.escape. Cgi.escape is deprecated and removed in newer pythons. Change your `extensions/timezone.py` file by applying the following patch manually:

    -import cgi
    +try:
    +    from html import escape
    +except ImportError:
    +    from cgi import escape

     try:
         import pytz

See https://issues.roundup-tracker.org/issue2551136 for more details.

## Migrating from 1.6.X to 2.0.0

### Python 2 MYSQL users MUST READ (required)

To fix issues with encoding of data and text searching, roundup now explicitly sets the database connection character set. Roundup prior to 2.0 used the default character set which was not always utf-8. All roundup data is manipulated in utf-8. This mismatch causes issues with searches and result in corrupted data in the database if it was not properly represented across the charset conversions.

This issue exists when running roundup under python 2. Note that there are more changes required for running roundup 2.0 if you choose to use python3. See Python 3 support.

In an upgraded `config.ini` (see next section) the `[rdbms]` section has a key `mysql_charset` set by default to `utf8mb4`.

It should be possible to change `utf8mb4` to any mysql charset. So if you know what charset is enabled (e.g. via a setting in ~roundup/.my.cnf, or the default charset for the database) you can set it in `config.ini` and not need to covert the database. However the underlying issues with misconverted data and bad searches will still exist if they did before.

None of the roundup developers run mysql, so the exact steps to take during the upgrade were tested with test and not production databases.

Before doing anything else:

> Backup the mysql database using mysql dump or other mysql supported tool.

> Backup roundup using your current backup tool and take the roundup instance offline.

Then the following steps (similar to the conversion in needed for Python 3) should work:

1. Export the tracker database using your current 1.6 instance:

       roundup-admin -i <trackerdir> exporttables <export_dir>

   replacing tracker_dir and export_dir as appropriate.

2. Import the exported database using the new 2.0 roundup:

       roundup-admin -i <trackerdir> importtables <export_dir>

   replacing tracker_dir and export_dir as appropriate.

The imported data should overwrite the original data. Note it is critically important that the `exporttables` be done with the old tracker and the `importtables` be done with the new tracker. An import/export cycle between roundup 1.6.0 and roundup 2.0 has been done successfully. So the export format for 1.6 and 2.0 should be compatible.

Note that `importtables` is new in roundup-2.0, so you will not be able to import the result of `exporttables` using any 1.x version of roundup.

Following the same sequence as above using `export` and `import` should also work, but it will export all the files and messages. This will take longer but may be worth trying if the `exporttables` and `importtables` method fails for some reason.

Another way that should be faster, but is untested is to use mysql dump to dump the database. https://makandracards.com/makandra/595-dumping-importing-mysql-utf-8-safe-way recommends:

> Note that when your MySQL server is not set to UTF-8 you need to do mysqldump –default-character-set=latin1 (!) to get a correctly encoded dump. In that case you will also need to remove the SET NAMES=’latin1’ comment at the top of the dump, so the target machine won’t change its UTF-8 charset when sourcing.

Then import the dump. Removing `SET NAMES` should allow the import to use UTF-8.

Please report success or issues with this conversion to the roundup-users at lists.sourceforge.net mailing list.

As people report successful or unsuccessful conversions, we will update the errata page at: https://wiki.roundup-tracker.org/ReleaseErrata.

### Upgrade tracker’s config.ini file (recommended)

Once you have installed the new roundup, use:

    roundup-admin -i /path/to/tracker updateconfig newconfig.ini

to generate a new ini file preserving all your settings. You can then merge any local comments from the tracker’s `config.ini` into `newconfig.ini`. Compare the old and new files and configure any new settings as you want. Then replace `config.ini` with the `newconfig.ini` file.

### Python 3 support (info)

Many of the `.html` and `.py` files from Roundup that are copied into tracker directories have changed for Python 3 support. If you wish to move an existing tracker to Python 3, you need to merge in those changes. Also you need to make sure that locally created python code in the tracker is correct for Python 3.

If your tracker uses the `anydbm` or `mysql` backends, you also need to export the tracker contents using `roundup-admin export` running under Python 2, and them import them using `roundup-admin import` running under Python 3. This is detailed in the documention for migrating to a different backend. If using the `sqlite` backend, you do not need to export and import, but need to delete the `db/otks` and `db/sessions` files when changing Python version. If using the `postgresql` backend, you do not need to export and import and no other special database-related steps are needed.

If you use the whoosh indexer, you will need to reindex. It looks like a database created with Python 2 leads to Unicode decode errors when accessed by Python 3. Reindexing can take a while (see details below look for “reindexing”).

Octal values in config.ini change from the Python 2 representation with a leading `0` (`022`). They now use a leading `0o` (`0o22`). Note that the `0o` format is properly handled under python 2. You can use the `newconfig.ini` generated using `python3 roundup-admin -i ... updateconfig newconfig.ini` if you want to go back to using python 2. (Note going back to Python 2 will require the same steps as moving from 2 to 3 except using Python 3 to perform the export.)

### Rate Limit New User Registration (info)

The new user registration form can be abused by bots to allow automated registration for spamming. This can be limited by using the new `config.ini` `[web]` option called `registration_delay`. The default is 4 and is the number of seconds between the time the form was generated and the time the form is processed.

If you do not modify the `user.register.html` template in your tracker’s html directory, you must set this to 0. Otherwise you will see the error:

    Form is corrupted, missing: opaqueregister.

If set to 0, the rate limit check is disabled.

If you want to use this, you can change your `user.register.html` file to include:

    <input type="hidden" name="opaqueregister" tal:attributes="value python: utils.timestamp()">

The hidden input field can be placed right after the form declaration that starts with:

    <form method="POST" onSubmit="return submit_once()"

If you have applied Erik Forsberg’s tracker level patch to implement (see: https://hg.python.org/tracker/python-dev/rev/83477f735132), you can back the code out of the tracker. You must change the name of the field in the html template to `opaqueregistration` from `opaque` in order to use the core code.

### PGP mail processing (required)

Roundup now uses the `gpg` module instead of `pyme` to process PGP mail. If you have PGP processing enabled, make sure the `gpg` module is installed.

### MySQL client module (recommended)

Although the `MySQLdb` module from https://pypi.org/project/MySQL-python/ is still supported, it is recommended to switch to the updated module from https://pypi.org/project/mysqlclient/.

### XMLRPC Access Role (info/required)

A new permission has been added to control access to the XMLRPC endpoint. If the user doesn’t have the new “Xmlrpc Access” permission, they will not be able to log in using the /xmlrpc end point. To add this new permission to the “User” role you should change your tracker’s schema.py and add:

    db.security.addPermissionToRole('User', 'Xmlrpc Access')

This is usually included near where other permissions like “Web Access” or “Email Access” are assigned.

### New values for db.tx_Source (info)

The database attribute tx_Source reports “xmlrpc” and “rest” when the /xmlrpc and /rest web endpoints are used. Check all code (extensions, detectors, lib) in trackers looking for tx_Source. If you have code like:

    if db.tx_Source == "web":

or:

    if db.tx_Source in ['web', 'email-sig-openpgp', 'cli' ]:

you may need to change these to include matches to “rest” and “xmlrpc”. For example:

    if db.tx_Source in [ "web", "rest", "xmlrpc" ]

or:

    if db.tx_Source in ['web', 'rest', 'xmlrpc', 'email-sig-openpgp', 'cli' ]:

### CSV export changes (info)

The original Roundup CSV export function for indexes reported id numbers for links. The wiki had a version that resolved the id’s to names, so it would report `open` rather than `2` or `user2;user3` rather than `[2,3]`.

Many people added the enhanced version to their extensions directory.

The enhanced version was made the default in roundup 2.0. If you want to use the old version (that returns id’s), you can replace references to `export_csv` with `export_csv_id` in templates.

Both core csv export functions have been changed to force quoting of all exported fields. To incorporate this change in any CSV export extension you may have added, change references in your code from:

    writer = csv.writer(wfile)

to:

    writer = csv.writer(wfile, quoting=csv.QUOTE_NONNUMERIC)

this forces all (non-numeric) fields to be quoted and empty quotes to be added for missing parameters.

This turns exported values that may look like formulas into strings so some versions of Excel won’t try to interpret them as a formula.

### Update userauditor.py to restrict usernames (recommended)

A username can be created with embedded commas and < and > characters. Even though the < and > are usually escaped when displayed, the embedded comma makes it difficult to edit lists of users as they are comma separated.

If you have not modified your tracker’s userauditor.py, you can just copy the userauditor.py from the classic template into your tracker’s detectors directory. Otherwise merge the changes from the template userauditor.py. https://issues.roundup-tracker.org/issue2550921 may be helpful.

### Consider reindexing if you use European languages (recommended)

A couple of bugs dealing with incorrect indexing of European languages (Russian and German were reported) have been fixed. Note reindexing all your data may take a long time. See: https://issues.roundup-tracker.org/issue1195739 and https://issues.roundup-tracker.org/issue1344046 for a description of the problem. If you determine that this a problem for your tracker, you can use:

    roundup-admin -i /path/to/tracker reindex

to rewrite your full text indexes. The tracker used for reindex timing had 140MB of file/message data and 2500 issues with a slow 5400RPM SATA drive. Using native indexing with sqlite took about 45 minutes. Using whoosh took about 2 hours. Using xapian took about 6 hours. All examples were with Python 2. Anecdotal evidence shows Python 3 is faster, but YMMV.

### Merge improvements in statusauditor.py (optional)

By default the detector statusauditor.py will change the status from “unread” to “chatting” when a second message is added to an issue. The distributed classic and jinja templates implement this feature in their copies of `detectors/statusauditor.py`.

This can be a problem. Consider a person sending email to create an issue. Then the person sends a followup message to add some additional information to the issue. The followup message will trigger the status change from “unread” to “chatting”. This is misleading since the person is “chatting” with themselves.

Statusauditor.py has been enhanced to prevent the status from changing to “chatting” until a second user (person) adds a message. If you want this functionality, you need to merge the distributed statusauditor.py with your tracker’s statusauditor.py. If you have not customised your tracker’s statusauditor.py, copy the one from the distibuted template. In addition to the python file, you also must copy/merge the distributed `detectors/config.ini` into your tracker’s detectors directory. Most people can copy `detectors/config.ini` from the distributed templates as they won’t have a `detectors/config.ini` file. (Note this is `detectors/config.ini` do not confuse it with the main `config.ini` file at the root of the tracker home.)

This enhancement is disabled by default. Enable it by changing the value in `detectors/config.ini` from:

    chatting_requires_two_users = False

to:

    chatting_requires_two_users = True

(the values `no` and `yes` can also be used). Restart the tracker to enable the change.

If you don’t do this quite right you will see one of two error messages in the web interface when you try to update an issue with a message:

    Edit Error: Unsupported configuration option: Option
       STATUSAUDITOR_CHATTING_REQUIRES_TWO_USERS not found in
       detectors/config.ini.
    Contact tracker admin to fix.

This happens if detectors/config.ini is not found or is missing the `chatting_requires_two_users` option in the `statusauditor` section.

If you have an incorrect value (say you use `T` rather than `True`) you see a different error:

    Edit Error: Invalid value for
      DETECTOR::STATUSAUDITOR_CHATTING_REQUIRES_TWO_USERS: 'T'
    Allowed values: yes, no

to fix this set the value to `yes` (True) or `no` (False).

### Responsive template changes (optional)

There have been some changes to the responsive template. You can diff/merge these changes into your responsive template based tracker.

### Jinja template changes (required)

Auto escaping has been enabled in the jinja template engine, this means it is no longer necessary to manually escape dynamic strings with `|e`, but strings that should not be escaped need to be marked with `|safe` (e.g. `{{ context.history()|u|safe }}`). Also, the i18n extension has been enabled and the template has been updated to use the extension for translatable text instead of explicit `i18n.gettext` calls:

    {% trans %}List of issues{% endtrans %}

instead of:

    {{ i18n.gettext('List of issues')|u }}

The jinja template has been upgraded to use bootstrap 4.1.3 (from 2.2.2). You can diff/merge changes into your jinja template based tracker.

Also search _generic.index.html, navigation.html and file.index.html in the html directory of your tracker. Look for:

    <input type="hidden" name="@action"

where the value is a jinja expression that calls i18n.gettext. Set the value to the argument of the gettext call. E.G. replace:

    <input type="hidden" name="@action" value="{{ i18n.gettext('editCSV')|u }}">

with:

    <input type="hidden" name="@action" value="editCSV">

The action keywords should not be translated.

## Migrating from 1.5.1 to 1.6.0

### Update tracker config file

After installing the new version of roundup, you should update the `config.ini` file for your tracker. To do this:

1. backup your existing `config.ini` file

2. using the newly installed code, run:

       roundup-admin -i /path/to/tracker updateconfig config.ini.new

   to create the file config.ini.new. Replace `/path/to/tracker` with the path to your tracker.

3. replace your tracker’s config.ini with config.ini.new

Using updateconfig keeps all the settings from your tracker’s config.ini file and adds settings for all the new options.

If you have added comments to your original config.ini file, merge the added comments into the config.ini.new file. Then replace your tracker’s config.ini with config.ini.new.

Read the new config.ini and configure it to enable new features. Details on using these features can be found in this section.

### Make sure that user can view labelprop on classes (required)

If you have View permissions that use `properties=...`, make sure that the labelprop for the class is listed in the properties list.

The first one of these that exists must must be in the list:

> 1. the property set by a call to setlabelprop for the class

> 2. the key of the class (as set by setkey())

> 3. the “name” property (if it exists)

> 4. the “title” property (if it exists)

if none of those apply, you must allow

> - the “id” property

E.G. If your class does a setlabelprop(“foo”) you must include “foo” in the properties list even if the class has name or title properties.

See: reference.html setlabelprop for further details on the labelprop.

If you don’t do this, you will find that multilinks (and possibly links) may not be displayed properly. E.G. templates that iterate over a mutlilink field (with tal:repeat for example) may not show any content.

See: https://sourceforge.net/p/roundup/mailman/message/35763294/ for the initial discussion of the issue.

### Cross Site Request Forgery Detection Added (recommended)

Roundup 1.6. supports a number of defenses against CSRF.

Http header verification against the tracker’s `web` setting in the `[tracker]` section of config.ini for the following headers:

1. Analyze the `Referer` HTTP header to make sure it includes the web setting.

2. Analyze the `Origin` HTTP header to make sure the schema://host matches the web setting.

3. Analyze the `X-Forwarded-Host` header set by a proxy running in front of roundup to make sure it agrees with the host part of the web setting.

4. Analyze the `Host` header to make sure it agrees with the host part of the web setting. This is not done if `X-Forwarded-Host` is set.

By default roundup 1.6 does not require any specific header to be present. However at least one of the headers above must pass validation checks (usually `Host` or `Referer`) or the submission is rejected with an error. If any header fails validation, the submission is rejected. (Note the user’s form keeps all the data they entered if it was rejected.)

Also the admin can include unique csrf tokens for all forms submitted using the POST method. (Delete and put methods are also included, but not currently used by roundup.) The csrf token (nonce) is tied to the user’s session. When the user submits the form and nonce, the nonce is checked to make sure it was issued to the user and the same session. If this is not true the post is rejected and the user is notified.

The standard context/submit templating item creates CSRF tokens by default. If you have forms using the POST method that are not using the standard submit routine, you should add the following field to all forms:

    <input name="@csrf" type="hidden"
       tal:attributes="value python:utils.anti_csrf_nonce()">

A unique random token is generated by every call to utils.anti_csrf_nonce() and is put in a database to be retreived if the token is used. Token lifetimes are 2 weeks by default but can be configured in config.ini. Roundup will automatically prune old tokens. Calling anti_csrf_nonce with an integer lifetime, for example:

    <input name="@csrf" type="hidden"
       tal:attributes="value python:utils.anti_csrf_nonce(lifetime=10)">

sets the lifetime of that nonce to 10 minutes.

If you want to change the default settings, you have to update the web section in your tracker’s config.ini file. Follow the section above to generate an updated config.ini file. Then look for settings that start with csrf. The updated config.ini file includes detailed descriptions of the settings.

In general one of four values can be set for these settings. The default is `yes`, which validates the header or nonce and blocks access if the validation fails. If the field/header is missing it allows access. Setting these fields to `required` blocks access if the header/nonce is missing.

It is recommended that you change your templates so every form that is not submitted via GET has an @csrf field. Then change the csrf_enforce_token setting to ‘required’.

#### Errors and Troubleshooting - @csrf in url

If you see the @csrf nonce in the URL, you have added the value to a form that uses the GET method. You should remove the @csrf token from these forms as it is not needed.

#### Errors and Troubleshooting - AttributeError list object no attribute value

If you get an error:

    AttributeError: 'list' object has no attribute 'value'

in handle_csrf, you have more than one @csrf token for the form. This usually occurs because the form uses the standard context/submit element but you also added an explicit @csrf statement. Simply remove the @csrf element for that form.

#### Errors and Troubleshooting - xmlrpc Required Header Missing

When performing and xmlrpc call, if you see something like:

    xmlrpclib.Fault: <Fault 1: "<class
       'roundup.exceptions.UsageError'>:Required Header Missing">

change your xmlrpc client to add appropriate headers to the request including the:

> X-Requested-With:

header as well as any other required csrf headers (e.g. referer, origin) configured in config.ini. See the advanced python client at the end of the xmlrpc guide.

Alternatively change the setting of csrf_enforce_header_x-requested-with in config.ini to `no`. So it looks like:

    csrf_enforce_header_x-requested-with = no

This is not recommended as it reduces csrf protection.

### Support for SameSite cookie option for session cookie

Support for serving the session cookie using the SameSite cookie option has been added. By default it is set to lax to provide a better user experience. But this can be changed to strict or the option can be removed entirely.

Using the process for merging config.ini changes described in Cross Site Request Forgery Detection Added you can add the `samesite_cookie_setting` to the `[web]` section of the config file.

### Fix for path traversal changes template resolution

The templates in the tracker’s html subdirectory must not be symbolic links that lead outside of the html directory.

If you don’t use symbolic links for templates in your html subdirectory you don’t have to make any changes. Otherwise you need to replace the symbolic links with hard links to the files or replace the symbolic links with the files.

This is a side effect of fixing a path traversal security issue. The security issue required a directory with a specific unusual name. This made it difficult to exploit. However allowing the use of subdirectories to organize the templates required that it be fixed.

### Database back end specified in config.ini (required)

The `db/backend_name` file is no longer used to configure the database backend being used for a tracker. The backend is now configured in the `config.ini` file using the `backend` option located in the `[rdbms]` section. For example if `db/backend_name` file contains `sqlite`, a new entry in the tracker’s `config.ini` will need to be created:

    [rdbms]

    ...

    # Database backend.
    # Default:
    backend = sqlite

Once the `config.ini` file has been updated with the new `backend` option, you can safely delete the `db/backend_name` file.

Note: the `backend_name` file may be located in a directory other than `db/` if you have configured the `database` option in the `[main]` section of the `config.ini` file to be something other than `db`.

Note 2: if you are using the anydbm back end, you still set it using the backend option in the rdbms section of the config.ini file.

### New config file option ‘indexer’ added

This release added support for the Whoosh indexer, so a new config file option has been added. You can force Roundup to use a particular text indexer by setting this value in the [main] section of the tracker’s `config.ini` file (usually placed right before indexer_stopwords):

    [main]

    ...

    # Force Roundup to use a particular text indexer.
    # If no indexer is supplied, the first available indexer
    # will be used in the following order:
    # Possible values: xapian, whoosh, native (internal).
    indexer =

#### Errors and Troubleshooting - Full text searching not working

If after the upgrade full text searching is not working try changing the indexer value. If this is failing most likely you need to set ‘’’indexer = native’’’ to use the rdbms or db text indexing systems.

Alternatively you can do a ‘’’roundup-admin -i /path/to/tracker reindex’’’ to generate a new index using roundup’s preferred indexer from the list above.

##### Xapian error with flint when reindexing

If you reindex and are using xapian, you may get the error that “flint” is not supported (looks like flint was removed after xapian 1.2.x). To fix this, you can delete the full text search database located in the tracker home directory in the file ‘’’db/text-index’’’ and then perform a reindex.

### Stemming improved in Xapian Indexer

Stemming allows a search for “silent” also match silently. The Porter stemmer in Xapian works with lowercase English text. In this release we lowercase the documents as they are put into the indexer.

This means capitalization is not preserved, but produces more hits by using the stemmer.

You will need to do a roundup-admin reindex if you are using the Xapian full text indexer on your tracker.

### New config file option ‘replyto_address’ added

A new config file option has been added to let you control the Reply-To header on nosy messages.

Edit your tracker’s `config.ini` and place the following after the email entry in the tracker section:

    [tracker]
    ...

    # Controls the reply-to header address used when sending
    # nosy messages.
    # If the value is unset (default) the roundup tracker's
    # email address (above) is used.
    # If set to "AUTHOR" then the primary email address of the
    # author of the change will be used as the reply-to
    # address. This allows email exchanges to occur outside of
    # the view of roundup and exposes the address of the person
    # who updated the issue, but it could be useful in some
    # unusual circumstances.
    # If set to some other value, the value is used as the reply-to
    # address. It must be a valid RFC2822 address or people will not be
    # able to reply.
    # Default:
    replyto_address =

### Login from a search or after logout works better (required)

The login form has been improved to work with some back end code changes. Now when a user logs in they stay on the same page where they started the login. To make this work, you must change the tal that is used to set the `__came_from` form variable. Note that the url assigned to __came_from must be url encoded/quoted and be under the tracker’s base url. If the base_url uses http, you can set the url to https.

Replace the existing code in the tracker’s html/page.html page that looks similar to (look for name=”__came_from”):

    <input type="hidden" name="__came_from" tal:attributes="value string:${request/base}${request/env/PATH_INFO}">

with the following:

    <input type="hidden" name="__came_from"
      tal:condition="exists:request/env/QUERY_STRING"
      tal:attributes="value string:${request/base}${request/env/PATH_INFO}?${request/env/QUERY_STRING}">
    <input type="hidden" name="__came_from"
      tal:condition="not:exists:request/env/QUERY_STRING"
      tal:attributes="value string:${request/base}${request/env/PATH_INFO}">

Now search backwards for the nearest form statement before the code that sets __came_from. If it looks like:

    <form method="post" action="#">

replace it with:

    <form method="post" tal:attributes="action request/base">

or with:

    <form method="post" tal:attributes="action string:${request/env/PATH_INFO}">

the important part is that the action field must not include any query parameters (‘#’ includes query params).

#### Errors and Troubleshooting - Unrecognized scheme in …

One symptom of failing to do this is getting an error:

> Unrecognized scheme in ….

where the …. changes depending on the url path. You can see this when logging in from any screen other than the main index.

### Option to make adding multiple keywords more convenient

In the classic tracker, after adding a new keyword you are redirected to the page for the new keyword so you can change the keyword’s name. This is usually not desirable as you usually correctly set the keyword’s name when creating the keyword. The new classic tracker has a new checkbox (checked by default) that keeps you on the same page so you can add a new keywords one after the other.

To add this to your own tracker, add the following code (prefixed with a +) after the entry box for the new keyword in html/keyword.item.html:

       <tr>
        <th i18n:translate="">Keyword</th>
        <td tal:content="structure context/name/field">name</td>
    +   <td tal:condition="not:context/id">
    +     <tal:comment tal:replace="nothing">
    +       If we get here and do not have an id, we are creating a new
    +       keyword. It would be nice to provide some mechanism to
    +       determine the preferred state of the "Continue adding keywords"
    +       checkbox. By default it is enabled.
    +     </tal:comment>
    +     <input type="checkbox" id="continue_new_keyword"
    +           name="__redirect_to"
    +           tal:attributes="value
    +                           string:${request/base}${request/env/PATH_INFO}?@template=item;
    +                           checked python:True" />
    +     <label for="continue_new_keyword" i18n:translate="">Continue adding keywords.</label>
    +   </td>
       </tr>

Note remove the leading ‘+’ when adding this to the templates.

The key component here is support for the ‘__redirect_to’ query property. It is a url which can be used when creating any new item (issue, user, keyword ….). It controls the next page displayed after creating the item. If ‘__redirect_to’ is not set, then you end up on the page for the newly created item. The url value assigned to __redirect_to must start with the tracker’s base url and must be properly url encoded.

### Helper popups trigger change events on the original page

The helper popups used to set dates (from a calendar), change lists of users or lists of issues did not notify the browser that the fields had been changed. This release adds code to trigger the change event.

To add the change event to the calendar popup, you don’t need to do any changes to the tracker. It is all done in the roundup python code in templating.py.

To add the change event when updating users using the help-submit template, copy share/roundup/templates/devel/html/_generic.help-submit.html and replace your tracker’s html/_generic.help-submit.html. If you have done local changes to this file, change your file to include the code that defines the onclick event for the input field with id=”btn_apply”.

To add the change event when updating lists of issues copy share/roundup/templates/devel/html/help_controls.js to your tracer’s html directory. If you have made local changes to the javascript file, merge the two if/else blocks labeled:

    /* trigger change event on the field we changed */

into your help_controls.js

### html/_generic.404.html in trackers use page template

The original generic 404 error pages for many trackers did not use the standard page layout. This change replaces the html/_generic.404.html page with one that uses the page template.

If your deployed tracker is based on: classic, minimal, responsive or devel templates and has not changed the html/_generic.404.html file, you can copy in the new file to get this additional functionality.

### Organize templates into subdirectories

The @template parameter to the web interface allows the use of subdirectories. So a setting of @template=view/view for an issue would use the template in the tracker’s html/view/issue.view.html. Similarly for a caller class, you could put all the templates under the html/caller directory with names like: html/caller/caller.item.html, html/caller/caller.index.html etc. You may want to symbolically link the html/_generic* templates into your subdirectory so that missing templates (e.g. a missing caller.edit.html template) can be satisfied by the _generic.edit.html template.

### Properly quote query dispname (displayed name) in page.html

A new method has been added to HTMLStringProperty called url_quote. The default templates have been updated to use this in the “Your Query” section of the trackers html/page.html file. You will want to change your template. Lines starting with - are the original line and you want to change it to match the line starting with the + (remove the + from the line):

        <tal:block tal:repeat="qs request/user/queries">
    -    <a href="#" tal:attributes="href string:${qs/klass}?${qs/url}&@dispname=${qs/name}"
    +    <a href="#" tal:attributes="href string:${qs/klass}?${qs/url}&@dispname=${qs/name/url_quote}"
            tal:content="qs/name">link</a><br>
        </tal:block>

Find the tal:repeat line that loops over all queries. Then change the value assigned to @dispname in the href attribute from ${qs/name} to ${qs/name/url_quote}. Note that you should not change the value for tal:content.

### Allow “Show Unassigned” issues link to work for Anonymous user

In this release the anonymous user is allowed to search the user class. The following was added to the schema for all templates that provide the search option:

    p = db.security.addPermission(name='Search', klass='user')
    db.security.addPermissionToRole ('Anonymous', p)

If you are running a tracker that does not allow read access for anonymous, you should remove this entry as it can be used to perform a username guessing attack against a roundup install.

#### Errors and Troubleshooting - Unassigned issues for anonymous

If you notice that the “Unassigned Issues” search on page.html is displaying assigned issues for users with the Anonymous role, you need to allow search permissions for the user class.

### Improvements in Classic Tracker query.edit.html template

There is a new query editing template included in the distribution at:

> `share/roundup/templates/classic/html/query.edit.html`

This template fixes:

> - public query could not be removed from “Your Queries” once it was added. Trying to do so would cause a permissions error.

> - private yes/no dropdown always showed “yes” regardless of underlying state

> - query Delete button did not work.

> - same query being displayed multiple times

It also adds:

  - the table layout displays queries created by the user first, then available public queries.

  - public query owners are shown

  - better support for deleted queries. When a query is deleted, it is still available for those who added it to their query list. If you are the query owner, you can restore (undelete) the query. If you are not the owner you can remove it from your query list. (If a query is deleted and nobody had it in their query list, it will not show up in the “Active retired queries” section. You will have to use the class editor or roundup_admin command line to restore it.)

  - notifies the user that delete/restore requires javascript. It always did, but that requirement wasn’t displayed.

To use the new template, you must add Restore permission on queries to allow the user to restore queries (see below).

If you have not modified the query.edit.html template in your tracker, you should be able to copy the new version from the location above. Otherwise you will have to merge the changes into your modified template.

Add the query Restore permission for the User role to your tracker’s schema.py file. Place it right after the query retire permission for the user role. After the change it should look like:

    p = db.security.addPermission(name='Retire', klass='query', check=edit_query,
        description="User is allowed to retire their queries")
    db.security.addPermissionToRole('User', p)
    p = db.security.addPermission(name='Restore', klass='query',
        check=edit_query,
        description="User is allowed to restore their queries")
    db.security.addPermissionToRole('User', p)

where the last four lines are the ones you need to add.

Usually you can add this to your User role. If all users have the User role in common then all logged in users should be ok. If you have users who do not include the User role (e.g. they may only have a Provisional role), you should add the search permission to that role (e.g. Provisional) as well if you allow them to edit their list of queries.

Also see the new search permissions for query in 1.4.17 section discussing search permission requirements for editing queries. The fixes in this release require the ability to search the creator of all queries to work correctly.

If the test script for the new search permissions for query in 1.4.17 doesn’t report that a role has the ability to search queries or at least search the creator property for queries, add the following permissions to your schema.py:

    s = db.security.addPermission(name='Search', klass='query',
      properties=['creator'],
      description="User is allowed to Search queries for creator")

#### Errors and Troubleshooting - Public queries listed twice when editing

If you do not do this, public queries will be listed twice in the edit interface. Once in the “Queries I created” section and again in the “Queries others created” section of the query edit page (`http..../query?@template=edit`).

### Fix security issues in query.item.html template

The default query.item.html template allows anybody to view all queries.

This has been updated in the classic, devel and responsive templates to only allow people to view queries they creates or queries that are publicly viewable.

If you haven’t modified you query.item.html template, simply copy the query.item.html template from one of the above default templates to your tracker’s html directory.

### Enhancement to check command for Permissions (optional)

A new form of check function is permitted in permission definitions. An example check function is `own_record(db, userid, itemid)` in the file schema.py. The three argument form is still supported and will work the same as it always has (although it may be depricated in the future).

If the check function is defined as:

    check(db, userid, itemid, **ctx)

the ctx variable will have the context to use when determining access rights:

    ctx['property'] the name of the property being checked or None if
           it's a class check.

    ctx['classname'] the name of the class that is being checked
           (issue, query ....).

    ctx['permission'] the name of the permission (e.g. View, Edit...).

This should make defining complex permissions much easier. Consider:

    def issue_private_access(db, userid, itemid, **ctx):
        if not db.issue.get(itemid, 'private'):
           # allow access to everything if not private
           return True

        # It is a private issue hide nosy list
        # Note that the nosy property *must* be listed
        # in permissions argument to the addPermission
        # definition otherwise this check command
        # is not run.
        if ctx['property'] == 'nosy':
           return False # deny access to this property

        # allow access for editing, viewing etc. of the class
        return True

    e = db.security.addPermission(name='Edit', klass='issue',
                                  check=issue_private_access,
                                  properties=['nosy'],
                                  description="Edit issue checks")

It is suggested that you change your checks to use the `**ctx` parameter. This is expected to be the preferred form in the future. You do not need to use the `ctx` parameter in the function if you do not need it.

If the new four argument form is required in the future, there will be required (not optional) directions on upgrading your schema.

### Changes to property permissions

If you create a permission:

    db.security.addPermission(name='View', klass='user',
       properties=['theme'], check=own_record,
       description="User is allowed to view their own theme")

that combines checks and properties, the permission also matches a permission check for the View permission on the user class. So this also allows the user to see their user record. It is unexpected that checking for access without a property would match this permission.

This release adds support for making a permission like above only be used during property permission tests. See `customizing.txt` and search for props_only and set_props_only_default in the section ‘Adding a new Permission’

### Improve query editing

If a user creates a query with the same name as one of their existing queries, the query editing interface will now report an error. By default the query editing page (issue.search.html) displays the index page when the search is triggered. This is usually correct since the user expects to see the results of the query. But now that the code properly checks for duplicate search names, the user should stay on the search page if there is an error. To add this to your existing issue.search.html page, add the following line after the hidden field `@old-queryname`:

    <input type="hidden" name="@template" value="index|search"/>

With this addition, the index template is displayed if there is no error, and the user stays on the search template if there is an error.

### New -L (loghttpvialogger) option to roundup-server

Http request logs from roundup-server are sent to stderr or can be recorded in a log file (if -l or the logfile options is used). However there is no way to rotate the logfile without shutting down and restarting the roundup-server.

If the -L flag is used, the python logging module is used for logging the http requests. The name for the log (qualname) is ‘roundup.http’. You can direct these messages to a rotating log file by putting the following:

    [loggers]
    keys=roundup.http

    [logger_roundup.http]
    level=INFO
    handlers=rotate_weblog
    qualname=roundup.http
    propagate=0

    [handlers]
    keys=rotate_weblog

    [handler_rotate_weblog]
    class=logging.handlers.RotatingFileHandler
    args=('httpd.log','a', 512000, 2)
    formatter=plain

    [formatters]
    keys=plain

    [formatter_plain]
    format=%(message)s

into a file (e.g. logging.ini). Then reference this file in the ‘config’ value of the [logging] section in the trackers config.ini file.

Note the log configuration above is an example and can be merged into a more full featured logging config file for your tracker if you wish. It will create a new file in the current working directory called ‘httpd.log’ and will rotate the log file at 500K and keep two old copies of the file.

## Migrating from 1.5.0 to 1.5.1

### User data visibility

For security reasons you should change the permissions on the user class. We previously shipped a configuration that allowed users to see too many of other users details, including hashed passwords under certain circumstances. In schema.py in your tracker, replace the line:

    db.security.addPermissionToRole('User', 'View', 'user')

with:

    p = db.security.addPermission(name='View', klass='user',
        properties=('id', 'organisation', 'phone', 'realname',
        'timezone', 'username'))
    db.security.addPermissionToRole('User', p)

Note that this removes visibility of user emails, if you want emails to be visible you can add ‘address’ and ‘alternate_addresses’ to the list above.

### XSS protection for custom actions

If you have defined your own cgi actions in your tracker instance (e.g. in a custom `extensions/spambayes.py` file) you need to modify all cases where client.error_message or client.ok_message are modified directly. Instead of:

    self.client.ok_message.append(...)

you need to call:

    self.client.add_ok_message(...)

and the same for:

    self.client.error_message.append(...)

vs.:

    self.client.add_error_message(...)

The new calls escape the passed string by default and avoid XSS security issues.
