Jeff King 85b87a5396 t/perf: handle worktrees as test repos
The perf suite gets confused when test_perf_default_repo is pointed at a
worktree (which includes when it is run from within a worktree at all,
since the default is to use the current repository).

Here's an example:

  $ git worktree add ~/foo
  Preparing worktree (new branch 'foo')
  HEAD is now at 328c109303 The eighth batch
  $ cd ~/foo
  $ make
  [...build output...]
  $ cd t/perf
  $ ./p0000-perf-lib-sanity.sh -v -i
  [...]
  perf 1 - test_perf_default_repo works:
  running:
  	foo=$(git rev-parse HEAD) &&
  	test_export foo

  fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.
  Use '--' to separate paths from revisions, like this:
  'git <command> [<revision>...] -- [<file>...]'

The problem is that we didn't copy all of the necessary files from the
source repository (in this case we got HEAD, but we have no refs!). We
discover the git-dir with "rev-parse --git-dir", but this points to the
worktree's partial repository in .../.git/worktrees/foo.

That partial repository has a "commondir" file which points to the main
repository, where the actual refs are stored, but we don't copy it. This
is the correct thing to do, though! If we did copy it, then our scratch
test repo would be pointing back to the original main repo, and any ref
updates we made in the tests would impact that original repo.

Instead, we need to either:

  1. Make a scratch copy of the original main repo (in addition to the
     worktree repo), and point the scratch worktree repo's commondir at
     it. This preserves the original relationship, but it's doubtful any
     script really cares (if they are testing worktree performance,
     they'd probably make their own worktrees). And it's trickier to get
     right.

  2. Collapse the main and worktree repos into a single scratch repo.
     This can be done by copying everything from both, preferring any
     files from the worktree repo.

This patch does the second one. With this applied, the example above
results in p0000 running successfully.

Git - fast, scalable, distributed revision control system

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.

Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.

Please read the file INSTALL for installation instructions.

Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.

See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-<commandname>.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.

CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).

The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.

Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.

The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.

The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):

  • random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
  • stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
  • "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
  • "goddamn idiotic truckload of sh*t": when it breaks
