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 filter will display tickets relevant to you:
- If logged in then all open tickets it will display open tickets assigned to you.
- If not logged in but you have specified a name or email address in the preferences then it will display all open tickets where your email (or name if email not defined) is in the CC list.
- If not logged and no name/email defined in the preferences then all open issues are displayed.
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 lists at the bottom corners of the filters box ('And' conditions on the left, 'Or' conditions on the right). 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
Trac allows you to save the query as a named query accessible from the reports module. To save a query ensure that you have Updated the view and then click the Save query button displayed beneath the results. You can also save references to queries in Wiki content, as described below.
Note: one way to easily build queries like the ones below, you can build and test the queries in the Custom report module and when ready - click Save query. This will build the query string for you. All you need to do is remove the extra line breaks.
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:
No results
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:
No results
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:
0
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 10340)
| Ticket | Resolution | Summary | Owner | Reporter |
|---|---|---|---|---|
| #10746 | fixed | Typo in programinfo.cpp affecting themes | David Engel <dengel@…> | mayfields@… |
| #10741 | Upstream Bug | Changing channels in LiveTV with HDPVR periodically fails on remote frontend | mitch.capper@… | |
| #10739 | Invalid | mythbackend periodic deadlock | andrew@… |
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 10340)
| Ticket | Resolution | Summary | Owner | Reporter |
|---|---|---|---|---|
| #10746 | fixed | Typo in programinfo.cpp affecting themes | David Engel <dengel@…> | mayfields@… |
| Description |
There is a typo in programinfo.cpp where recordinggroup is mis-spelled. The particular spelling (recordingggroup) only occurs once in the code base. This means themes have no data populated when including this field. A workaround is to alter theme but this is not ideal as most themes include this field spelled as recordinggroup. Present in master as well as 0.25-fixes. Patch as follows: --- a/libs/libmyth/programinfo.cpp 2012-04-24 17:35:58.000000000 +0930

| #10741 | Upstream Bug | Changing channels in LiveTV with HDPVR periodically fails on remote frontend | mitch.capper@… | |
| Description |
When in liveTV on a remote frontend tuned with the HDPVR and changing to a new channel on the HDPVR the change to the new channel plays for 2 seconds or so then pauses then freezes. Problem is not reproducible with other inputs including dual tuner hd home run or hd5500. Problem only occurs on remote frontends. Problem does not occur with -prerecorded programs. Problem does not happen with initially entering live-tv only when changing channels when the HDPVR is already tuned to a specific channel and is changed to another. Problem occurs if the guide is on screen or when changing just using the OSD with channel up and down. Frontend and backend should be are within 1 second of each other for time. Currently running on 568e161f39a33cde70ba1a74081ab46d28006a2c (may 4th) Has been happening for at least many months. Tried with signal_timeout set to 1000 and 4000 and channel_timeout at 3000 and 12000 on the hdpvr card. I attached the log files running with -v all and without -v at all. Both showing the same situation. For the non verbose a timeline is: 16:36:28 - enter live TV and enters without problem on channel 280 16:36:51 - hit guide button 16:37:18 - changed to channel 278 16:37:30 - playes a few seconds of video and freezes 16:37:43 - plays another second of video completed frozen 16:38:16 - kicked out of live TV video buffering error On the frontend running local to the backend it shows a similar behavior with a pause when changing channels after playing a 2-3 seconds of video but then it continues normally. For the verbose logs the channel change is at 16:21:36 channel was changed to a new channel(280) |

| #10739 | Invalid | mythbackend periodic deadlock | andrew@… | |
| Description |
My backend is experiencing periodic deadlocks after applying http://code.mythtv.org/trac/attachment/ticket/10541/10541-v2.patch to mythtv-0.25_rc20120510.ebuild MYTHTV_VERSION="v0.25-85-g77d0afc" MYTHTV_BRANCH="fixes/0.25", MYTHTV_REV="77d0afc9b155161c402abc328edae86b0c97a797" MYTHTV_SREV="77d0afc" I would add to #10541 but there is a comment there that the deadlock is fixed buy the second patch (which I am using), so this is probably a completely unrelated problem. If I take this patch out of my e-build I end up with periodic crashes of the backend (1-2 times a week) instead, so they may be related in some way. I have an always on backend and slave frontends which connect to it as required. Approx 1 to 2 times a week a frontend will fail to connect to the backend process, at which time I have to ssh on to the backend and killall -9 before re-starting the backend (a standard kill doesn't seem to be enough). |

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. To include a litteral & or | in a value, escape the character with a backslash (\).
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 |
The date fields created and modified can be constrained by using the = operator and specifying a value containing two dates separated by two dots (..). Either end of the date range can be left empty, meaning that the corresponding end of the range is open. The date parser understands a few natural date specifications like "3 weeks ago", "last month" and "now", as well as Bugzilla-style date specifications like "1d", "2w", "3m" or "4y" for 1 day, 2 weeks, 3 months and 4 years, respectively. Spaces in date specifications can be left out to avoid having to quote the query string.
| created=2007-01-01..2008-01-01 | query tickets created in 2007 |
| created=lastmonth..thismonth | query tickets created during the previous month |
| modified=1weekago.. | query tickets that have been modified in the last week |
| modified=..30daysago | query tickets that have been inactive for the last 30 days |
