brian m. carlson 2c02b110da t: add test functions to translate hash-related values 
Add several test functions to make working with various hash-related
values easier.

Add test_oid_init, which loads common hash-related constants and
placeholder object IDs from the newly added files in t/oid-info.
Provide values for these constants for both SHA-1 and SHA-256.

Add test_oid_cache, which accepts data on standard input in the form of
hash-specific key-value pairs that can be looked up later, using the
same format as the files in t/oid-info.  Document this format in a
t/oid-info/README directory so that it's easier to use in the future.

Add test_oid, which is used to specify look up a per-hash value
(produced on standard output) based on the key specified as its
argument.  Usually the data to be looked up will be a hash-related
constant (such as the size of the hash in binary or hexadecimal), a
well-known or placeholder object ID (such as the all-zeros object ID or
one consisting of "deadbeef" repeated), or something similar.  For these
reasons, test_oid will usually be used within a command substitution.
Consequently, redirect the error output to standard error, since
otherwise it will not be displayed.

Add test_detect_hash, which currently only detects SHA-1, and
test_set_hash, which can be used to set a different hash algorithm for
test purposes.  In the future, test_detect_hash will learn to actually
detect the hash depending on how the testsuite is to be run.

Use the local keyword within these functions to avoid overwriting other
shell variables.  We have had a test balloon in place for a couple of
releases to catch shells that don't have this keyword and have not
received any reports of failure.  Note that the varying usages of local
used here are supported by all common open-source shells supporting the
local keyword.

Test these new functions as part of t0000, which also serves to
demonstrate basic usage of them.  In addition, add documentation on how
to format the lookup data and how to use the test functions.

Implement two basic lookup charts, one for common invalid or synthesized
object IDs, and one for various facts about the hash function in use.
Provide versions of the data for both SHA-1 and SHA-256.

Since we use shell variables for storage, names used for lookup can
currently consist only of shell identifier characters.  If this is a
problem in the future, we can hash the names before use.

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-.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://public-inbox.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
