Priority: normal Milestone: 1.3.1
Component: general Version:
Severity: normal Keywords:
Cc: Branch:

Removed deprecated functions, classes, attributes and methods.

Description (last modified by Ryan J Ollos)

This ticket lists code that is scheduled for removal in Trac 1.3.1.

  • Removal of ipnr attribute in attachment and wiki modules: #9612.
  • Remove deprecated methods in trac.wiki.formatter: #11539.
  • Remove deprecated notification code (comment:21:ticket:3517).
  • Remove svn_fs.py and svn_prop.py (modules moved in #10712).
  • Remove since strings from code comments and option documentation for features added in Trac < 1.0 (as in [13889])

Other changes:

Building the list will be easier to do as we develop, and the changes can then be removed at the start of the milestone.

TracDev/ApiChanges/1.3 should be updated with the API changes before this ticket is closed.

I was going to make a list of code to remove in this ticket, but it seemed easier to just prepare a branch. I'll periodically rebase the branch against the trunk and commit the changes at the start of milestone:1.3.1. The first revision of the changes will be posted here after #11913 is committed at the start of milestone:1.0.4.

I was going to make a list of code to remove in this ticket, but it seemed easier to just prepare a branch.

Some changes have been staged in log:rjollos.git:t11901-remove-deprecated-code-in-1.3.1. I haven't removed all of the deprecated code, in particular the notification module code. The upgrade step for removing the ipnr columns from the database also hasn't been written yet (#11872 could help with that).

show_email_addresses was deprecated from the chrome data dictionary in #11474 / [14151#file2] and will be removed in the next set of proposed changes.

comment:21 by Ryan J Ollos, 9 years ago

[3751] may have some compatibility code to be removed, which we might even be able to do on the currently trunk. We'd have to replace HTTPInternalError with HTTPInternalServerError in the half-dozen or so instances that it appears in the Trac codebase. TracDev/Exceptions should be updated if the change is made.

It appears the following built-ins don't need to be passed in the data dictionary any longer: tags/trac-1.1.6/trac/web/chrome.py@:597-598,622,625#L594.

I've also considered that it would be generally useful to pass functools, itertools and operator in the chrome data dictionary. Previously we've discussed passing presentation (comment:15:ticket:8989).

[1a9ad113/rjollos.git] attempts a minor simplification of Ticket.save_changes. Is there any reason to wait until the end of the method to update self.values['changetime']? I've considered that an exception might be raised in the method, but haven't come up with a scenario in which the change would cause a problem.

comment:34 by Ryan J Ollos, 9 years ago

Expanding on the changes in #11565 and #11587, I propose in [327fadb1/rjollos.git] to remove the deprecated systeminfo attribute, deprecate ISystemInfoProvider and add a lazily-evaluated system_info property.

This would finally cleanup the Environment class by:

  • Eliminating get_systeminfo which has a name too similar to get_system_info.
  • Forcing plugins to implement the ISystemInfoProvider interface rather than appending to systeminfo.

Rebased changes in log:rjollos.git:t11901-remove-deprecated-code-in-1.3.1.13. Environment.get_repository has been removed.

comment:36 by Ryan J Ollos, 9 years ago

Since [4559], the version info is retrieved from an attribute if Pygments is installed from source, or more specifically if the version can't be retrieved from package info: tags/trac-1.0.9/trac/mimeview/pygments.py@:89-91#L85.

I'm not entirely sure what installed from source means, but I assume it means installed in dev mode.

It looks like we can remove the complexity. I've evaluated with Pygments 2.1dev (which is post-2.1, so it appears the version hasn't been bumped after the 2.1 release) and 1.0 (minimum Pygments version bumped to 1.0 in comment:29).

Pygments installed in dev mode from tip of Hg repository:

>>> import pygments
>>> from trac.util import get_pkginfo
>>> pkginfo = get_pkginfo(pygments)
>>> pkginfo['version']
'2.1.dev20160119'
>>> pygments.__version__
'2.1'

Pygments 1.0 installed in dev mode.

>>> import pygments
>>> from trac.util import get_pkginfo
>>> pkginfo = get_pkginfo(pygments)
>>> pkginfo['version']
'1.0'
>>> pygments.__version__
'1.0'

comment:50 by Ryan J Ollos, 8 years ago

EnvironmentStub.reset_db was implemented in [8194#file4], prior to the introduction of database transaction context managers. I can see the case for calling rollback in the original implementation, but I'm less sure that call is necessary now that transaction context managers are used: trunk/trac/test.py@15050:377#L366. Shouldn't the content manager rollback any transactions when __exit__ is called?

Yeah. The changes look good to me. I agree no need to call rollback because Environment.get_db_cnx() has been removed in 1.3.1dev.

I think it's good to use BatchModifyModule with IRequestFilter rather than self.env[BatchModifyModule] in QueryModule. Also, I consider it's good to apply it to 1.0-stable.

comment:72 by Ryan J Ollos, 8 years ago

The options ambiguous_char_width, ticket_subject_template and batch_subject_template are defined on the TicketNotificationSystem class, which is an artifact of the old notification system: tags/trac-1.2/trac/ticket/notification.py@:63,72,77#L42. Now that the legacy code is removed the values are only used in TicketFormatter. I think it makes sense to make the Options class attributes of TicketFormatter, so that if TicketFormatter is replaced by a plugin we don't have unused Options. Failure to move those when removing the legacy notification code was an oversight by me.
