Subject: [PATCH v2 0/7] Let log-tree and friends respect diffopt's `file` field
Date: Mon, 20 Jun 2016 12:55:02 +0200 (CEST) [thread overview]
Message-ID: <cover.1466420060.git.johannes.schindelin@gmx.de> (raw)
In-Reply-To: <cover.1466244194.git.johannes.schindelin@gmx.de>
The idea is to allow callers to redirect log-tree's output to a file
without having to freopen() stdout (which would modify global state,
a big no-no-no for library functions).
I reviewed log-tree.c, graph.c, line-log.c, builtin/shortlog.c and
builtin/log.c line by line to ensure that all calls that assumed stdout
previously now use the `file` field instead, of course. I would
welcome additional eyes to go over the code to confirm that I did not
miss anything.
This patch series ends up removing the freopen() call in the
format-patch command, but that is only a by-product. The ulterior motive
behind this series is to allow the sequencer to write a `patch` file as
part of my endeavor to move large chunks of rebase -i into a builtin.
Speaking of said endeavor: it is going a lot slower than I would like,
but I really need rebase -i to be robust. To that end, I not only review
and re-review my patches frequently, I also use a cross-validation
technique inspired by my original ll-merge validation as well as
GitHub's Scientist library: I taught rebase -i to run every interactive
rebase twice, once with the original shell script's code, and once with
the builtin rebase--helper, and then to verify that the end result is as
similar as can be expected (the commit dates will differ most of the
time, of course).
It is a bit tedious, of course, because I have to resolve every merge
conflict twice, I have to reword everything twice (identically!), and I
have to wait longer for the rebase to finish. It is worth it, though,
because I really need rebase -i to be robust, as it is the center piece
of almost all of my workflows.
I organized the patch series into a thicket of branches, to make it
easier to review them; In addition to this here patch series, I plan to
submit 11 separate, partially interdependent series, resubmit another
one, and I already submitted a couple of patches earlier that were
integrated or replaced by superior solutions (thanks, Peff!). Skipping
the temporary patches (e.g. for cross-validation), that leaves me with
99 patches to submit in total (sing with me: "99 patches of code to
submit, 99 patches of code, ...").
I was curious just how much these patches could accelerate rebase -i, so
I disabled the cross-validation temprarily and let Travis measure the
performance improvements via the t/perf test that was already merged to
`master`. Look for "3404.2" in this build's logs:
https://travis-ci.org/git/git/builds/138277774
It looks like a 3x speedup on Linux, a 4x speedup on MacOSX and my local
measurements suggest a >5x speed-up on Windows.
Johannes Schindelin (7):
log-tree: respect diffopt's configured output file stream
line-log: respect diffopt's configured output file stream
graph: respect the diffopt.file setting
shortlog: support outputting to streams other than stdout
format-patch: explicitly switch off color when writing to files
format-patch: avoid freopen()
format-patch: use stdout directly
