Karthik Nayak a52d459e72 bundle: fix non-linear performance scaling with refs 
The 'git bundle create' command has non-linear performance with the
number of refs in the repository. Benchmarking the command shows that
a large portion of the time (~75%) is spent in the
`object_array_remove_duplicates()` function.

The `object_array_remove_duplicates()` function was added in
b2a6d1c686 (bundle: allow the same ref to be given more than once,
2009-01-17) to skip duplicate refs provided by the user from being
written to the bundle. Since this is an O(N^2) algorithm, in repos with
large number of references, this can take up a large amount of time.

Let's instead use a 'strset' to skip duplicates inside
`write_bundle_refs()`. This improves the performance by around 6 times
when tested against in repository with 100000 refs:

Benchmark 1: bundle (refcount = 100000, revision = master)
  Time (mean ± σ):     14.653 s ±  0.203 s    [User: 13.940 s, System: 0.762 s]
  Range (min … max):   14.237 s … 14.920 s    10 runs

Benchmark 2: bundle (refcount = 100000, revision = HEAD)
  Time (mean ± σ):      2.394 s ±  0.023 s    [User: 1.684 s, System: 0.798 s]
  Range (min … max):    2.364 s …  2.425 s    10 runs

Summary
  bundle (refcount = 100000, revision = HEAD) ran
    6.12 ± 0.10 times faster than bundle (refcount = 100000, revision = master)

Previously, `object_array_remove_duplicates()` ensured that both the
refname and the object it pointed to were checked for duplicates. The
new approach, implemented within `write_bundle_refs()`, eliminates
duplicate refnames without comparing the objects they reference. This
works because, for bundle creation, we only need to prevent duplicate
refs from being written to the bundle header. The `revs->pending` array
can contain duplicates of multiple types.

First, references which resolve to the same refname. For e.g. "git
bundle create out.bdl master master" or "git bundle create out.bdl
refs/heads/master refs/heads/master" or "git bundle create out.bdl
master refs/heads/master". In these scenarios we want to prevent writing
"refs/heads/master" twice to the bundle header. Since both the refnames
here would point to the same object (unless there is a race), we do not
need to check equality of the object.

Second, refnames which are duplicates but do not point to the same
object. This can happen when we use an exclusion criteria. For e.g. "git
bundle create out.bdl master master^!", Here `revs->pending` would
contain two elements, both with refname set to "master". However, each
of them would be pointing to an INTERESTING and UNINTERESTING object
respectively. Since we only write refnames with INTERESTING objects to
the bundle header, we perform our duplicate checks only on such objects.

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.adoc to get started, then see Documentation/giteveryday.adoc for a useful minimum set of commands, and Documentation/git-<commandname>.adoc 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.adoc (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 and Documentation/CodingGuidelines).

Those wishing to help with error message, usage and informational message string translations (localization l10) should see po/README.md (a po file is a Portable Object file that holds the translations).

To subscribe to the list, send an email to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). The mailing list archives are available at https://lore.kernel.org/git/, https://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
