Trac Ticket Queries

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.

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.

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

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, 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:

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 14612)

#17831 invalid Unable to easily move vitrtual machine files -- awesome14

Reported by awesome14, 2 days ago.

Description

Virtualbox is way behind the scenes in comparison to VMware Workstation, which has always permitted VMs to be freely and easily moved and copied by just moving or copying the related files.

Virtualbox creates a fiasco over what should be a simple operation. There is no reason the path to the virtual machine files needs to be constant, and that the machine should fail if it changes. A notification would be sufficient.

In my case, I had to reactivate Windows 7 and create a new user. And my user-installed programs vanished! There is no reason the guest should even be aware the VM-related files have been moved!

Virtualbox fails if the path to the VM-related files changes, because the UUIDs remain the same. Even if the original path no longer exists, it fails! Again, this serves no good purpose. It just makes life more difficult. A notification would be sufficient.

There is also no reason the machine should fail if it can't find a shared directory. A warning would be sufficient.

Virtualbox fails on so many inconsequential things it seems senseless. The VMs should be portable; totally self-contained! The rigmarole serves no purpose but to make things difficult, and perhaps to generate the need for paid support!

But if the latter is the case, we might as well use VMware!

#17829 invalid Issue with Windows update -- CMienie

Reported by CMienie, 3 days ago.

Description

My Qiime enjin does not start in VirtualBox. It was working fine before a Windows update that ran on 14/15 June. I have tried the following: Reinstalled the VirtualBox (latest edition). Upgraded Windows Home edition to Windows Pro. Uninstalled and reinstalled VirtualBox several times. Restored Windows to a previous restore point on suggestion from a Microsoft technician and uninstalled VirtualBox again. Ran CCleaner and reinstalled VirtualBox. Is there anything I can try without reformatting my laptop? Please help.

#17826 invalid Middle of screen not updating correctly in 4K. Guest - MacOS High Sierra 10.13.5 -- PhillB

Reported by PhillB, 7 days ago.

Description

The screen does not update correctly once the full screen resolution is set beyond 2560x1440(x32).

Resolution set using: <ExtraDataItem name="VBoxInternal2/EfiGraphicsResolution" value="3840x2160"/>

Once the mouse moves beyond about X1100 only every 8th pixel updates. Then after about X1800 it works again. So the mouse seems to disappear in this vertical band.

Refreshing the screen by toggling out of full screen and then back updates everything correctly. In my mind that points to the guest screen buffer being filled correctly. However, it seems the buffer isn't always copied to KDE.

Guest: MacOS High Sierra Version 10.13.5. 256MB VRAM, 8GB RAM

Host: F27, KDE 5.12.5, Frameworks 5.46.0, Qt 5.9.4, Kernel 4.16.13-200.fc27.x86-64 8 x Intel Xeon CPU E3-1245 v5 @3.5GHz, 32GB Ram, NVidia GForce GTX1060 6GB, Driver 390.59

Windows10 guest @ 4K runs fine. Fedora27, Oracle EL7.5, Centos..... all fine.

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
