Subject: [PATCH 6/9] gdb: remove unnecessary notification of executable_changed observer
Date: Sat, 16 Sep 2023 11:18:07 +0100 [thread overview]
Message-ID: <019cf397b93d42ee8f6d8d7db536d2e4048724c1.1694858967.git.aburgess@redhat.com> (raw)
In-Reply-To: <cover.1694858967.git.aburgess@redhat.com>
This commit continues the work of the previous two commits.
My goal, in the next couple of commits, is to expose the
executable_changed observable in the Python API as an event. However,
before I do that I want to remove the use of the executable_changed
observable from the reread_symbols function in symfile.c as this use
isn't directly associated with a change of the executable file, and so
seems wrong.
In the previous two commits I have removed all users of the
executable_changed observer as I believe those users can, and should,
actually be listening for the new_objfile observable instead, so now
there are no users of the executable_changed observable.
As such, I think removing the use of executable_changed from the
function reread_symbols is perfectly safe, and correct. At this point
the executable has not been changed, so we shouldn't be sending an
executable_changed notification, and, as there is nobody listening to
this observable, we can't break anything by removing this call.
There should be no user visible changes after this commit.
