26.0.50; poor interaction between flymake and desktop-save-mode |
|

When I start Emacs after editing a bunch of Python files,
desktop-save-mode restores them and flymake starts syntax checking
processes in each of them.
However, there is a snag: python virtual environments.
Basically, each python projects uses a separate virtual environments
which includes its own python packages, and, moreover, its own python
and pylint executables(!)
This means that flymake fails to find the epylint executable and
displays a GUI popup(!) for each(!) python file that I edited in the
previous session. Note that this failure should _not_ be fatal (see PS
below).
You can imagine, I am sure, how frustrating it is to have to click on
"OK" (or even hit "esc") 30 times before Emacs actually starts.
The workaround is to customize `flymake-gui-warnings-enabled' to nil,
but this is only one part of the problem.
The necessary fixes would entail:
* flymake should only display GUI warnings in response to a manual
action, not when desktop-save-mode restores a buffer.
* the initial failure in desktop-save-mode should "defer" flymake rather
than "disable" it permanently.
PS. Fixing the following will probably require pyvenv-specific work and
is outside the core Emacs issues, but maybe you have suggestions:
This initial failure, apparently, makes flymake _disable_ itself in all
restored buffers, so I have to re-enable it manually (if & when I notice
that it is not running there).
When I select the Python virtual environment using the pyvenv-workon
command (I might also disable virtual environment altogether or switch
between them &c), the location of the epylint executable should change.

Having read the discussion, it seems like this issue was fixed by Glenn
in the above commit. The rest is discussing something which we don't
know what it means, and something which is outside Emacs development.
Since there seems to be nothing more to do here, I'm closing this bug
report.
If this conclusion is incorrect, please reply to this email (use "Reply
to all" in your email client) and we can reopen the bug report. Thanks.
Best regards,
Stefan Kangas
