- By instantiating only on activation, an ugly "white" gap
appears where there is no widget at all. So instantiate
earlier so that the widget already exists and is painting
by the time the slideshow part is visible.
- This makes the net effect of this branch so far zero:
the slideshow is still loaded and started when Calamares starts.
- Update coding style (more braces!) and coding documentation,
reformat parts. The idea is to go through and re-do the
coding style across the whole codebase incrementally, but
systematically, in the next release or two.
- astyle can do some things that clang-format doesn't (e.g.
adding brackets; you need clang-tidy for that),
- clang-format does a much nicer job with lambdas and certain
other constructions,
- allow passing in directories at a time for formatting.
- since we mix Python (indentation is important) with C++ (it isn't),
having indented one-line blocks which suddenly need {} when a
statment is added is confusing and error-prone. Instead, make
the blocks explicit, always, in C++.
- From an exec section, next() is called automatically when
all the jobs in that section are done.
- If there **is** no next section (e.g. there's no finished
page to show after the exec), then m_steps.at() would assert
on an out-of-range index.
- Introdcuce a helper predicate isAtVeryEnd() which handles both
out-of-range and normal at-the-end scenarios.
- If there's no page following the exec section, stay with the
slideshow but update buttons to match the normal last-page
behavior, and don't ask about cancel (since we're done).
- This avoids processes that wait on stdin, and e.g. improves
reaction to having just "cat" (no file) in a command, or
a package manager that asks for input.
- JobQueue is only needed to get global settings, which are needed
when running in the target; for host commands, allow running
without a queue.
- Settings is needed for the value of debugsettings; assume if
there's no settings object, that we're in a test and should
print debugging information.
- This is the same as EFAIL: a block is indented as if it's a multi-
line else block. This isn't Python though, and the return always
applies.
- Add the necessary braces.
- Apparently noone uses this code path (until ProcessJob was re-
factored to do so).
- Use the system runCommand() instead of a 90% copy of it.
This **does** change the overall command to `env /bin/sh -c`
rather than running only `/bin/sh -c`, though.
- Replace magic numbers like -3 with named enum values
(NoWorkingDirectory, for -3).
- Downside is big-ugly static_casts, but that's what you get
for having an int as return value for processes.
- This solves a crash where the thread is destroyed while still
running (e.g. cancelling during install).
- The thread might not cooperate in being terminated, but then we
have a bigger problem anyway (and Calamares will still crash on
exit).
