Trac Ticket Queries
Table of Contents
In addition to reports, Trac provides support for custom ticket queries, used to display lists of tickets meeting a specified set of criteria.
To configure and execute a custom query, switch to the View Tickets module from the navigation bar, and select the Custom Query link.
Filters
When you first go to the query page the default filters will display all open tickets, or if you're logged in it will display open tickets assigned to you. Current filters can be removed by clicking the button to the right with the minus sign on the label. New filters are added from the pulldown list in the bottom-right corner of the filters box. Filters with either a text box or a pulldown menu of options can be added multiple times to perform an or of the criteria.
You can use the fields just below the filters box to group the results based on a field, or display the full description for each ticket.
Once you've edited your filters click the Update button to refresh your results.
Navigating Tickets
Clicking on one of the query results will take you to that ticket. You can navigate through the results by clicking the Next Ticket or Previous Ticket links just below the main menu bar, or click the Back to Query link to return to the query page.
You can safely edit any of the tickets and continue to navigate through the results using the Next/Previous/Back to Query links after saving your results. When you return to the query any tickets which were edited will be displayed with italicized text. If one of the tickets was edited such that it no longer matches the query criteria the text will also be greyed. Lastly, if a new ticket matching the query criteria has been created, it will be shown in bold.
The query results can be refreshed and cleared of these status indicators by clicking the Update button again.
Saving Queries
While Trac does not yet allow saving a named query and somehow making it available in a navigable list, you can save references to queries in Wiki content, as described below.
Using TracLinks
You may want to save some queries so that you can come back to them later. You can do this by making a link to the query from any Wiki page.
[query:status=new|assigned|reopened&version=1.0 Active tickets against 1.0]
Which is displayed as:
This uses a very simple query language to specify the criteria (see Query Language).
Alternatively, you can copy the query string of a query and paste that into the Wiki link, including the leading ?
character:
[query:?status=new&status=assigned&status=reopened&group=owner Assigned tickets by owner]
Which is displayed as:
Using the [[TicketQuery]]
Macro
The TicketQuery macro lets you display lists of tickets matching certain criteria anywhere you can use WikiFormatting.
Example:
[[TicketQuery(version=0.6|0.7&resolution=duplicate)]]
This is displayed as:
- #181
- Wiki preview injects new lines
- #204
- request for colour legend (or something similar) for ticket groups in reports
- #226
- Ticket Dependencies
- #239
- Link to diff of specifik wiki change instead of the page itself
- #351
- All ticket modifications should be tracked in timeline
- #413
- Installing on Windows, drive other than C:
- #450
- Diffviewer should try to convert the text into utf-8.
- #475
- merging of similar tickets
- #519
- Python process sometimes hangs on Windows Server 2003
- #529
- IE 5-6 over HTTPS broken downloads
Just like the query: wiki links, the parameter of this macro expects a query string formatted according to the rules of the simple ticket query language.
A more compact representation without the ticket summaries is also available:
[[TicketQuery(version=0.6|0.7&resolution=duplicate, compact)]]
This is displayed as:
Finally if you wish to receive only the number of defects that match the query using the count
parameter.
[[TicketQuery(version=0.6|0.7&resolution=duplicate, count)]]
This is displayed as:
Customizing the table format
You can also customize the columns displayed in the table format (format=table) by using col≤field> - you can specify multiple fields and what order they are displayed by placing pipes (|
) between the columns like below:
[[TicketQuery(max=3,status=closed,order=id,desc=1,format=table,col=resolution|summary|owner|reporter)]]
This is displayed as:
Results (1 - 3 of 11260)
Full rows
In table format you can also have full rows by using rows≤field> like below:
[[TicketQuery(max=3,status=closed,order=id,desc=1,format=table,col=resolution|summary|owner|reporter,rows=description)]]
This is displayed as:
Results (1 - 3 of 11260)
Ticket | Resolution | Summary | Owner | Reporter |

#13742 | fixed | spamfilter.bayes is missing a dependency | ||
Description |
Hi,
We recently updated our Trac instance to 1.6 (thanks for the release by the way) and were hit by a spam wave almost immediately after. We're using the After scratching our heads for a few ours, we finally saw this in the log: 01:30:52 PM Trac[loader] ERROR: Skipping "spamfilter.bayes = tracspamfilter.filters.bayes": ModuleNotFoundError: No module named 'filelock'
As far as I could find, the requirement for [1] https://pypi.org/project/TracSpamFilter/ [2] https://trac.edgewall.org/wiki/SpamFilter |

#13704 | cantfix | Minor error doing a repository resync | ||
Description |
Hi! I'm having a minor issue doing a trac-admin repository resync. I'm using Python 3.9.18, SVN 1.14.3 and Trac 1.6 on macOS 10.14.6. It always stops at revision 1934 (of 2215) with this error message: sudo trac-admin /Users/trac repository resync "*" Återsynkroniserar historik för arkivet (default)... Fatal Python error: none_dealloc: deallocating None Python runtime state: initialized Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/cmd.py", line 214, in onecmd func = getattr(self, 'do_' + cmd) AttributeError: 'TracAdmin' object has no attribute 'do_repository' During handling of the above exception, another exception occurred: StopIteration zsh: abort sudo trac-admin /Users/trac repository resync "*" Doing a repository sync, rather than a resync, it continues the sync and finishes, and everything seems to be working just fine. Not sure what the issue might be and I'm not sure when it started since it was a while ago since I did a resync… |

#13634 | fixed | cache invalidation for Environment::get_known_users can cause DB temp space exhaustion with MySQL backend | ||
Description |
On larger Trac deployments (ours has several backend servers, each with multiple worker processes) with frequent accesses the cache invalidation logic essentially implements a trigger for a "thundering herd": when the generation counter is increased then all worker processes will rather quickly run the query in Environment::_known_users. Looks all normal and harmless on first sight, but:
MySQL creates a temporary table each for such That's the "point of no return": the query wasn't finished yet but the worker will issue another one. This growing avalanche of queries (all limited by IO performance and needing 8MB of temp table space each) will exhaust the disk space of the DB server at the maximum IO performance, using all CPU and memory resources on the way too. No wonder with about 1500 such queries running simultaneously at the end (they build up over 45 to 60 minutes in our case). Once the disk space is exhausted the MySQL server goes into "offline mode", needing a server restart (until that happens Trac is obviously down). After the restart everything is perfectly working again. Temporary tables are automatically removed, therefore the disk usage is back to normal.
Proposed solution: remove the Reference: MySQL 8.0 documentation about internal use of temporary tables |
Query Language
query:
TracLinks and the [[TicketQuery]]
macro both use a mini “query language” for specifying query filters. Basically, the filters are separated by ampersands (&
). Each filter then consists of the ticket field name, an operator, and one or more values. More than one value are separated by a pipe (|
), meaning that the filter matches any of the values.
The available operators are:
= | the field content exactly matches the one of the values |
~= | the field content contains one or more of the values |
^= | the field content starts with one of the values |
$= | the field content ends with one of the values |
All of these operators can also be negated:
!= | the field content matches none of the values |
!~= | the field content does not contain any of the values |
!^= | the field content does not start with any of the values |
!$= | the field content does not end with any of the values |
