Subject: [PATCH v3 0/4] run-command.c: print env vars when GIT_TRACE is set
Date: Fri, 12 Jan 2018 16:56:03 +0700	[thread overview]
Message-ID: <20180112095607.18293-1-pclouds@gmail.com> (raw)
In-Reply-To: <20180111094712.2551-1-pclouds@gmail.com>

v3 turns a single patch into a series. Changes from v2

- env var quoting is now done correctly (from shell syntax perspective)
- the program name is prepended in git_cmd mode
- cwd is now printed too (because I have too, see 4/4)
- we don't blindly print the env delta anymore but print the actual
  differences compared to parent env
- which means we also print "unset XXX" statements in $GIT_TRACE

The new output on git.git looks like this

    trace: run_command: cd 'sha1collisiondetection'; unset GIT_PREFIX; GIT_DIR='.git' git 'status' '--porcelain=2'

a bit longer than I would like, but that's because of
sha1collisiondetection and it's not long enough for me to invent
$GIT_TRACE_EXEC.

I'm not adding "sh -c" back though because that looks like it should
be done in run_command.c itself, not just output tracing output.

Oh.. before anybody asks, I'm not adding git prefix to the "cd" part.
You're supposed to know that git moves back to worktree top dir when
you read $GIT_TRACE (or are welcome to improve the print out).

Nguyễn Thái Ngọc Duy (4):
  trace.c: introduce trace_run_command()
  trace.c: print program 'git' when child_process.git_cmd is set
  trace.c: print env vars in trace_run_command()
  trace.c: be smart about what env to print in trace_run_command()

 run-command.c |   3 +-
 trace.c       | 106 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
 trace.h       |   3 ++
