Trac Ticket Queries

In addition to reports, Trac provides support for custom ticket queries, which can be used to display tickets that meet specified 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 in and no name/email is 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 on 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.

After you have edited your filters, click the Update button to refresh your results.

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.

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:

Active tickets against 1.0

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:

Assigned tickets by owner

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 in by placing pipes (|) between the columns:

[[TicketQuery(max=3,status=closed,order=id,desc=1,format=table,col=resolution|summary|owner|reporter)]]

This is displayed as:

Results (1 - 3 of 3765)

1 2 3 4 5 6 7 8 9 10 11
Ticket Resolution Summary Owner Reporter
#3851 Fixed Block Commented Includes Jos seadoggie01
#3850 Fixed _WinAPI_GetDriveNumber never returns -1 as partition number Jpm AspirinJunkie
#3848 Fixed _GUICtrlListView_GetItemTextArray does not return an error for multi-column listview if no row is selected. Jpm BugFix
1 2 3 4 5 6 7 8 9 10 11

Full rows

In table format you can also have full rows by using rows=<field>:

[[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 3765)

1 2 3 4 5 6 7 8 9 10 11
Ticket Resolution Summary Owner Reporter
#3851 Fixed Block Commented Includes Jos seadoggie01
Description

Block commented out include files are reported as being missing. "!->Includefile <NonExistantInclude.au3> not found." Test code:

#cs
#include <NonExistantInclude.au3>

#3850 Fixed _WinAPI_GetDriveNumber never returns -1 as partition number Jpm AspirinJunkie
Description

The documentation for _WinAPI_GetDriveNumber says:

[2] - The partition number, or (-1) if device cannot be partitioned.

This is consistent with the description of the STORAGE_DEVICE_NUMBER structure.

However, the problem here is that the PartitionNumber part is of data type DWORD - i.e. an unsigned integer. A value of -1 is therefore simply not possible. In C this is not a big problem, because DWORDs can also be tested for -1:

(DWORD)4294967295 == -1 // true

In AutoIt, however, 4294967295 is always returned in the case of -1 due to the conversion to Int64:

#include <WinAPIFiles.au3>

Local $aData = _WinAPI_GetDriveNumber('d:') ; a non partionable drive like a cd-drive
ConsoleWrite('Partition number: ' & $aData[2] & @CRLF)

Therefore, as a pragmatic solution, I suggest to change the structure definition as follows, deviating from the Win API documentation:

Local $tSDN = DllStructCreate('dword;dword;LONG')
#3848 Fixed _GUICtrlListView_GetItemTextArray does not return an error for multi-column listview if no row is selected. Jpm BugFix
Description

I had written a function _GUICtrlListView_SetItemTextArray as a counterpart to _GUICtrlListView_GetItemTextArray. In doing so, I noticed that it was not possible to determine if _GUICtrlListView_GetItemTextArray was successful. In the help it says: Failure: Array with the following format: [0] - Number of Columns in array (0). This is only correct for the case of a listview with one column. Otherwise an empty array with column count +1 elements is returned: [iCount, '', '', ..]. But this cannot be distinguished from a valid empty array (row could be empty). This is caused by the function _GUICtrlListView_GetItemTextString. In this function, if -1 is passed as index, the index of the selected row is used. This is returned by _GUICtrlListView_GetNextItem. However, if no line is marked, the return is -1. Since this value is not checked, the queries of all (sub)items for index -1 are now executed with _GUICtrlListView_GetItemText. This causes empty strings and data separators to be strung together. The result, although false, is returned without error detection.

In my modifications (_GUICtrlListView_GetItemTextArray_MOD, _GUICtrlListView_GetItemTextString_MOD) I have integrated the index check and thus it can be determined whether _GUICtrlListView_GetItemTextArray() was successful. (see my test script) In general, I think it is recommended that all functions that work with indexes also check them for validity. Many functions call each other and the user has no possibility to check their result and find sources of errors.

Query Language

query: TracLinks and the [[TicketQuery]] macro both use a mini “query language” for specifying query filters. Filters are separated by ampersands (&). Each filter 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 omitted 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
