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 left 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.
Note: you must have the REPORT_CREATE permission in order to save queries to the list of default reports. The Save query button will only appear if you are logged in as a user that has been granted this permission. If your account does not have permission to create reports, you can still use the methods below to save a query.
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. This also allows displaying the link and description of a single ticket:
[[TicketQuery(id=123)]]
This is displayed as:
- #123
- savannah: 2GB file size limit in fish
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, use 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 2668)
| Ticket | Resolution | Summary | Owner | Reporter |
|---|---|---|---|---|
| #4533 | fixed | External editor does not work with command line argument | andrew_b | Dhalgren |
| #4532 | fixed | Preserve ext2fs attributes on copy/move operations | andrew_b | andrew_b |
| #4531 | duplicate | /bin/sh is not supported for mc as a subshell | phegumda |
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 2668)
| Ticket | Resolution | Summary | Owner | Reporter |
|---|---|---|---|---|
| #4533 | fixed | External editor does not work with command line argument | andrew_b | Dhalgren |
| Description |
When using an external editor for the "Edit" command (i.e. "Use internal edit" in the Configure Options is unchecked) the environment variable EDITOR is used. However, if $EDITOR contains a command line argument after the executable name, these arguments are not processed properly, and the editor might not be started at all. How to reproduce: (Precondition: vi is available on the system) 1.) On the command line, execute: export EDITOR="vi +" && mc (the + argument should let vi start at the document's end instead of the beginning) 2.) Go to the Options menu -> Configuration -> uncheck "Use internal edit" 3.) Move the cursor to a file that is larger than a single screen (e.g. ABOUT-NLS in mc's source directory) 4.) Press F4 to start the external editor Result: Nothing visible happens Expected result: vi is opened showing the end of the file ABOUT-NLS Output of LC_MESSAGES=C mc -V: GNU Midnight Commander 4.8.30 Built with GLib 2.78.3 Built with S-Lang 2.3.3 with terminfo database Built with libssh2 1.11.0 With builtin Editor With subshell support as default With support for background operations With mouse support on xterm and Linux console With support for X11 events With internationalization support With multiple codepages support With ext2fs attributes support Virtual File Systems: cpiofs, tarfs, sfs, extfs, ftpfs, sftpfs Data types: char: 8; int: 32; long: 64; void *: 64; size_t: 64; off_t: 64; Output of LC_MESSAGES=C mc -F: Home directory: /home/user

I have determined the cause of the problem and will provide a fix (which works for a single command line argument) via Pull Request. Summary: In function utilunix.c:my_system_make_arg_array the GPtrArray storing the contents of argv is not filled correctly. |

| #4531 | duplicate | /bin/sh is not supported for mc as a subshell | phegumda | |
| Description |
After a FreeBSD 14.0 fresh install you are going to face with strange error when you want to run mc command after installing it. It says: common.c: unimplemented subshell type 1 read (subshell_pty...): No such file or directory (2) The problem: FreeBSD 14.0 changed the default shell to /bin/sh which is not supported for mc as a subshell. The subshell is a forked process that you can run command in the background while mc is running, the hotkey to bring it up is CTRL + O. The Workaround: Change back your shell to /bin/csh. That is the way: pw user mod root -s /bin/csh |

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 literal & or | in a value, escape the character with a backslash (\).
The available operators are:
| = | the field content exactly matches 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 |
