- The last part of the module import path is the module name. This also
becomes the Django app name. Apps names have to be unique. Hence,
there is no scope for two different modules with same name but
different load path to exist in the project.
- Most uses of list of loaded modules are dealing with app names instead
of full module load path. This is due to the fact that Django deals
with app names and not module paths.
- It is also somewhat clumsy to access a loaded module as we are
re-importing every time to get access module.
- Simplify all of the above by using app names are module identifiers
and maintaing an ordered dictionary of app names to loadded modules.
- Remove unused imports.
- Minor styling fixes.
- Closes#366 and closes#304 (all sub-tasks).
- Start new process group with setsid() by sending
start_new_session=True
- Detach from parent process fds by closing all FDs and attaching stdin,
stdou and stderr to /dev/null.
- Don't wait for the process to complete.
- This allows for upgrading Plinth while upgrades are trigged from
Plinth itself.
- Show log of upgrade exection instead of output and error log of the
process which can no longer be collected. This has the advantage of
showing automatic executions also.
- Rewrite the mechanism to detect whether upgrades can be run. It is
now based on whether the package manager is busy. This has the
advantage of working properly if other apt processes are running,
automatic upgrades are running, etc.
- Busy status works even if Plinth is restarted while upgrades are in
progress.
- More descriptive messages showing that upgrades don't have to be
triggered manually.
- Warn that other packages can't be installed while upgrades are
running, which may take a long time.
- Warn the users of potential temporary unavailability of
Plinth/Apache2.
- Show error message based on return code rather than messages in
stderr.
- Don't decorate the message paragraph with alert color, we are already
doing that by showing a message at the top.
- Untabify.
- Improve message showing that upgrades are running, gramatically.
- Show errors messages decorated as errors.
- Minor cleanups.
- For each application, add ./tests directory and __init__.py file
within it.
- Modify test controllers (coverage.py, runtests.py) to find the new
test directories for testing and coverage analysis.
- Move existing application-specific test modules (test_pagekite.py) to
the newly created directories.
- Remove emacs mode line as emacs automatically detect Python files
based on the #! line.
- End comments with a '.'.
- Use single quotes instead of double quotes for string for consistensy.
- Update message to say that it take more than a minute to finish
upgrades. Some times it takes a lot more than that.
