Derrick Stolee 9479a31d60 advice: warn when sparse index expands
Typically, forcing a sparse index to expand to a full index means that
Git could not determine the status of a file outside of the
sparse-checkout and needed to expand sparse trees into the full list of
sparse blobs. This operation can be very slow when the sparse-checkout
is much smaller than the full tree at HEAD.

When users are in this state, there is usually a modified or untracked
file outside of the sparse-checkout mentioned by the output of 'git
status'. There are a number of reasons why this is insufficient:

 1. Users may not have a full understanding of which files are inside or
    outside of their sparse-checkout. This is more common in monorepos
    that manage the sparse-checkout using custom tools that map build
    dependencies into sparse-checkout definitions.

 2. In some cases, an empty directory could exist outside the
    sparse-checkout and these empty directories are not reported by 'git
    status' and friends.

 3. If the user has '.gitignore' or 'exclude' files, then 'git status'
    will squelch the warnings and not demonstrate any problems.

In order to help users who are in this state, add a new advice message
to indicate that a sparse index is expanded to a full index. This
message should be written at most once per process, so add a static
global 'give_advice_on_expansion' to sparse-index.c. Further, there is a
case in 'git sparse-checkout set' that uses the sparse index as an
in-memory data structure (even when writing a full index) so we need to
disable the message in that kind of case.

The t1092-sparse-checkout-compatibility.sh test script compares the
behavior of several Git commands across full and sparse repositories,
including sparse repositories with and without a sparse index. We need
to disable the advice in the sparse-index repo to avoid differences in
stderr. By leaving the advice on in the sparse-checkout repo (without
the sparse index), we can test the behavior of disabling the advice in
convert_to_sparse(). (Indeed, these tests are how that necessity was
discovered.) Add a test that reenables the advice and demonstrates that
the message is output.

The advice message is defined outside of expand_index() to avoid super-
wide lines. It is also defined as a macro to avoid compile issues with
-Werror=format-security.

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 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
