Subject: [PATCH v2 8/8] progress.c: add & assert a "global_progress" variable
Date: Tue, 21 Sep 2021 01:09:29 +0200	[thread overview]
Message-ID: <patch-v2-8.8-1bd285eba0d-20210920T225701Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-v2-0.8-00000000000-20210920T225701Z-avarab@gmail.com>

The progress.c code makes a hard assumption that only one progress bar
be active at a time (see [1] for a bug where this wasn't the
case). Add a BUG() that'll trigger if we ever regress on that promise
and have two progress bars active at the same time.

There was an alternative test-only approach to doing the same
thing[2], but by doing this outside of a GIT_TEST_* mode we'll know
we've put a hard stop to this particular API misuse.

It will also establish scaffolding to address current fundamental
limitations in the progress output: The current output must be
"driven" by calls to the likes of display_progress(). Once we have a
global current progress object we'll be able to update that object via
SIGALRM. See [3] for early code to do that.

It's conceivable that this change will hit the BUG() condition in some
scenario that we don't currently have tests for, this would be very
bad. If that happened we'd die just because we couldn't emit some
pretty output.

See [4] for a discussion of why our test coverage is lacking; our
progress display is hidden behind isatty(2) checks in many cases, so
the test suite doesn't cover it unless individual tests are run in
"--verbose" mode, we might also have multi-threaded use of the API, so
two progress bars stopping and starting would only be visible due to a
race condition.

Despite that, I think that this change won't introduce such
regressions, because:

 1. I've read all the code using the progress API (and have modified a
    large part of it in some WIP code I have). Almost all of it is really
    simple, the parts that aren't[5] are complex in the display_progress() part,
    not in starting or stopping the progress bar.

 2. The entire test suite passes when instrumented with an ad-hoc
    Linux-specific mode (it uses gettid()) to die if progress bars are
    ever started or stopped on anything but the main thread[6].

    Extending that to die if display_progress() is called in a thread
    reveals that we have exactly two users of the progress bar under
    threaded conditions, "git index-pack" and "git pack-objects". Both
    uses are straightforward, and they don't start/stop the progress
    bar when threads are active.

 3. I've likewise done an ad-hoc test to force progress bars to be
    displayed with:

        perl -pi -e 's[isatty\((?:STDERR_FILENO|2)\)][1]g' $(git grep -l 'isatty\((STDERR_FILENO|2)\)')

    I.e. to replace all checks (not just for progress) of checking
    whether STDERR is connected to a TTY, and then monkeypatching
    is_foreground_fd() in progress.c to always "return 1". Running the
    tests with those applied, interactively and under -V reveals via:

        $ grep -e set_progress_signal -e clear_progress_signal test-results/*out

    That nothing our tests cover hits the BUG conditions added here,
    except the expected "BUG: start two concurrent progress bars" test
    being added here.

    That isn't entirely true since we won't be getting 100% coverage
    due to cascading failures from tests that expected no progress
    output on stderr. To make sure I covered 100% I also tried making
    the display() function in progress.c a NOOP on top of that (it's
    the calls to start_progress_delay() and stop_progress()) that
    matter.

    That doesn't hit the BUG() either. Some tests fail in that mode
    due to a combination of the overzealous isatty(2) munging noted
    above, and the tests that are testing that the progress output
    itself is present (but for testing I'd made display() a NOOP).

Between those three points I think it's safe to go ahead with this
change.
