Fixes since v1.5.6.2
--------------------
+* Setting core.sharerepository to traditional "true" value was supposed to make
+ the repository group writable but should not affect permission for others.
+ However, since 1.5.6, it was broken to drop permission for others when umask is
+ 022, making the repository unreadable by others.
+
* Setting GIT_TRACE will report spawning of external process via run_command().
+* Using an object with very deep delta chain pinned memory needed for extracting
+ intermediate base objects unnecessarily long, leading to excess memory usage.
+
* Bash completion script did not notice '--' marker on the command
line and tried the relatively slow "ref completion" even when
completing arguments after one.
tree file for it confused "racy-git avoidance" logic into thinking
that the path is now unchanged.
+* The section that describes attributes related to git-archive were placed
+ in a wrong place in the gitattributes(5) manual page.
+
+* "git am" was not helpful to the users when it detected that the committer
+ information is not set up properly yet.
+
* "git clone" had a leftover debugging fprintf().
* "git clone -q" was not quiet enough as it used to and gave object count
good thing if the remote side is well packed but otherwise not,
especially for a project that is not really big.
-* The section that describes attributes related to git-archive were placed
- in a wrong place in the gitattributes(5) manual page.
+* "git daemon" used to call syslog() from a signal handler, which
+ could raise signals of its own but generally is not reentrant. This
+ was fixed by restructuring the code to report syslog() after the handler
+ returns.
* When "git push" tries to remove a remote ref, and corresponding
tracking ref is missing, we used to report error (i.e. failure to
MIME multipart mail correctly.

+GIT v1.6.0 Release Notes
+========================
+
+User visible changes
+--------------------
+
+With the default Makefile settings, most of the programs are now
+installed outside your $PATH, except for "git", "gitk", "git-gui" and
+some server side programs that need to be accessible for technical
+reasons. Invoking a git subcommand as "git-xyzzy" from the command
+line has been deprecated since early 2006 (and officially announced in
+1.5.4 release notes); use of them from your scripts after adding
+output from "git --exec-path" to the $PATH is still supported in this
+release, but users are again strongly encouraged to adjust their
+scripts to use "git xyzzy" form, as we will stop installing
+"git-xyzzy" hardlinks for built-in commands in later releases.
+
+Source changes needed for porting to MinGW environment are now all in the
+main git.git codebase.
+
+By default, packfiles created with this version uses delta-base-offset
+encoding introduced in v1.4.4. Pack idx files are using version 2 that
+allows larger packs and added robustness thanks to its CRC checking,
+introduced in v1.5.2.
+
+GIT_CONFIG, which was only documented as affecting "git config", but
+actually affected all git commands, now only affects "git config".
+GIT_LOCAL_CONFIG, also only documented as affecting "git config" and
+not different from GIT_CONFIG in a useful way, is removed.
+
+An ancient merge strategy "stupid" has been removed.
+
+
+Updates since v1.5.6
+--------------------
+
+(subsystems)
+
+* git-p4 in contrib learned "allowSubmit" configuration to control on
+ which branch to allow "submit" subcommand.
+
+* git-gui learned to stage changes per-line.
+
+(portability)
+
+* Changes for MinGW port have been merged, thanks to Johannes Sixt and
+ gangs.
+
+* Sample hook scripts shipped in templates/ are now suffixed with
+ *.sample. We used to prevent them from triggering by default by
+ relying on the fact that we install them as unexecutable, but on
+ some filesystems this approach does not work. Instead of running
+ "chmod +x" on them, the users who want to activate these samples
+ as-is can now rename them dropping *.sample suffix.
+
+* perl's in-place edit (-i) does not work well without backup files on Windows;
+ some tests are rewritten to cope with this.
+
+(documentation)
+
+* Updated howto/update-hook-example
+
+* Got rid of usage of "git-foo" from the tutorial and made typography
+ more consistent.
+
+* Disambiguating "--" between revs and paths is finally documented.
+
+(performance, robustness, sanity etc.)
+
+* even more documentation pages are now accessible via "man" and "git help".
+
+* reduced excessive inlining to shrink size of the "git" binary.
+
+* verify-pack checks the object CRC when using version 2 idx files.
+
+* When an object is corrupt in a pack, the object became unusable even
+ when the same object is available in a loose form, We now try harder to
+ fall back to these redundant objects when able. In particular, "git
+ repack -a -f" can be used to fix such a corruption as long as necessary
+ objects are available.
+
+* git-clone does not create refs in loose form anymore (it behaves as
+ if you immediately ran git-pack-refs after cloning). This will help
+ repositories with insanely large number of refs.
+
+* core.fsyncobjectfiles configuration can be used to ensure that the loose
+ objects created will be fsync'ed (this is only useful on filesystems
+ that does not order data writes properly).
+
+* "git commit-tree" plumbing can make Octopus with more than 16 parents.
+ "git commit" has been capable of this for quite some time.
+
+(usability, bells and whistles)
+
+* A new environment variable GIT_CEILING_DIRECTORIES can be used to stop
+ the discovery process of the toplevel of working tree; this may be useful
+ when you are working in a slow network disk and are outside any working tree,
+ as bash-completion and "git help" may still need to run in these places.
+
+* git-apply can handle a patch that touches the same path more than once
+ much better than before.
+
+* git-apply can be told not to trust the line counts recorded in the input
+ patch but recount, with the new --recount option.
+
+* git-archive can be told to omit certain paths from its output using
+ export-ignore attributes.
+
+* git-clone can clone from a remote whose URL would be rewritten by
+ configuration stored in $HOME/.gitconfig now.
+
+* git-diff --check now checks leftover merge conflict markers.
+
+* When remote side used to have branch 'foo' and git-fetch finds that now
+ it has branch 'foo/bar', it refuses to lose the existing remote tracking
+ branch and its reflog. The error message has been improved to suggest
+ pruning the remote if the user wants to proceed and get the latest set
+ of branches from the remote, including such 'foo/bar'.
+
+* fast-export learned to export and import marks file; this can be used to
+ interface with fast-import incrementally.
+
+* "git rerere" can be told to update the index with auto-reused resolution
+ with rerere.autoupdate configuration variable.
+
+* git-send-mail can talk not just over SSL but over TLS now.
+
+* You can tell "git status -u" to even more aggressively omit checking
+ untracked files with --untracked-files=no.
+
+* Original SHA-1 value for "update-ref -d" is optional now.
+
+* Error codes from gitweb are made more descriptive where possible, rather
+ than "403 forbidden" as we used to issue everywhere.
+
+(internal)
+
+
+Fixes since v1.5.6
+------------------
+
+All of the fixes in v1.5.6 maintenance series are included in
+this release, unless otherwise noted.
+
+ * "git fetch" into an empty repository used to remind the fetch will
+ be huge by saying "no common commits", but it is already known by
+ the user anyway (need to backport 8cb560f to 'maint').

You can override these rules either by command line options or by environment
variables. The '--global' and the '--system' options will limit the file used
to the global or system-wide file respectively. The GIT_CONFIG environment
variable has a similar effect, but you can specify any filename you want.

-the name used instead of the repository configuration file. The global and

ENVIRONMENT
-----------
Using the "--global" option forces this to ~/.gitconfig. Using the

SPECIFYING RANGES

of commits, not just a single commit. To these commands,
specifying a single revision with the notation described in the
previous section means the set of commits reachable from that

This set operation appears so often that there is a shorthand
-for it. "`r1..r2`" is equivalent to "`{caret}r1 r2`". It is
-the difference of two sets (subtract the set of commits
-reachable from `r1` from the set of commits reachable from
-`r2`).
+for it. When you have two commits `r1` and `r2` (named according
+to the syntax explained in SPECIFYING REVISIONS above), you can ask
+for commits that are reachable from r2 excluding those that are reachable
+from r1 by "`{caret}r1 r2`" and it can be written as "`r1..r2`".
A similar notation "`r1\...r2`" is called symmetric difference
of `r1` and `r2` and is defined as
-"`r1 r2 --not $(git-merge-base --all r1 r2)`".
+"`r1 r2 --not $(git merge-base --all r1 r2)`".
It is the set of commits that are reachable from either one of
`r1` or `r2` but not from both.

DESCRIPTION
-----------
-This manual describes best practice in how to use git CLI. Here are
-the rules that you should follow when you are scripting git:
+This manual describes the convention used throughout git CLI.
+
+Many commands take revisions (most often "commits", but sometimes
+"tree-ish", depending on the context and command) and paths as their
+arguments. Here are the rules:
+
+ * Revisions come first and then paths.
+ E.g. in `git diff v1.0 v2.0 arch/x86 include/asm-x86`,
+ `v1.0` and `v2.0` are revisions and `arch/x86` and `include/asm-x86`
+ are paths.
+
+ * When an argument can be misunderstood as either a revision or a path,
+ they can be disambiguated by placing `\--` between them.
+ E.g. `git diff \-- HEAD` is, "I have a file called HEAD in my work
+ tree. Please show changes between the version I staged in the index
+ and what I have in the work tree for that file". not "show difference
+ between the HEAD commit and the work tree as a whole". You can say
+ `git diff HEAD \--` to ask for the latter.
+
+ * Without disambiguating `\--`, git makes a reasonable guess, but errors
+ out and asking you to disambiguate when ambiguous. E.g. if you have a
+ file called HEAD in your work tree, `git diff HEAD` is ambiguous, and
+ you have to say either `git diff HEAD \--` or `git diff \-- HEAD` to
+ disambiguate.
+
+When writing a script that is expected to handle random user-input, it is
+a good practice to make it explicit which arguments are which by placing
+disambiguating `\--` at appropriate places.
+
+Here are the rules regarding the "flags" that you should follow when you are
+scripting git:
* it's preferred to use the non dashed form of git commands, which means that
you should prefer `"git foo"` to `"git-foo"`.
if you happen to have a file called `HEAD` in the work tree.
-ENHANCED CLI
-------------
+ENHANCED OPTION PARSER
+----------------------
From the git 1.5.4 series and further, many git commands (not all of them at the
time of the writing though) come with an enhanced option parser.
----------------------------
+NOTES ON FREQUENTLY CONFUSED OPTIONS
+------------------------------------
+
+Many commands that can work on files in the working tree
+and/or in the index can take `--cached` and/or `--index`
+options. Sometimes people incorrectly think that, because
+the index was originally called cache, these two are
+synonyms. They are *not* -- these two options mean very
+different things.
+
+ * The `--cached` option is used to ask a command that
+ usually works on files in the working tree to *only* work
+ with the index. For example, `git grep`, when used
+ without a commit to specify from which commit to look for
+ strings in, usually works on files in the working tree,
+ but with the `--cached` option, it looks for strings in
+ the index.
+
+ * The `--index` option is used to ask a command that
+ usually works on files in the working tree to *also*
+ affect the index. For example, `git stash apply` usually
+ merges changes recorded in a stash to the working tree,
+ but with the `--index` option, it also merges changes to
+ the index as well.
+
+`git apply` command can be used with `--cached` and
+`--index` (but not at the same time). Usually the command
+only affects the files in the working tree, but with
+`--index`, it patches both the files and their index
+entries, and with `--cached`, it modifies only the index
+entries.
+
+See also http://marc.info/?l=git&m=116563135620359 and

the output from diffcore-pathspec is used as the input to the

output routine and generates either diff-raw format (see Output

The first transformation in the chain is diffcore-pathspec, and

Here again it is a good point to take a pause.
So, think about something which you are interested in, say, "how can I

Issues of note:
- - git normally installs a helper script wrapper called "git", which
- conflicts with a similarly named "GNU interactive tools" program.
-
- Tough. Either don't use the wrapper script, or delete the old GNU
- interactive tools. None of the core git stuff needs the wrapper,
- it's just a convenient shorthand and while it is documented in some
- places, you can always replace "git commit" with "git-commit"
- instead.
-
- But let's face it, most of us don't have GNU interactive tools, and
- even if we had it, we wouldn't know what it does. I don't think it
- has been actively developed since 1997, and people have moved over to
- graphical file managers.
-
- NOTE: As of gnuit-4.9.2, the GNU interactive tools package has been
- renamed. You can compile gnuit with the --disable-transition
- option and then it will not conflict with git.
+ - Ancient versions of GNU Interactive Tools (pre-4.9.2) installed a
+ program "git", whose name conflicts with this program. But with
+ version 4.9.2, after long hiatus without active maintenance (since
+ around 1997), it changed its name to gnuit and the name conflict is no
+ longer a problem.
+
+ NOTE: When compiled with backward compatiblity option, the GNU
+ Interactive Tools package still can install "git", but you can build it
+ with --disable-transition option to avoid this.
- You can use git after building but without installing if you
wanted to. Various git commands need to find other git

+appp.sh is a script that is supposed to be used together with ExternalEditor
+for Mozilla Thundebird. It will let you include patches inline in e-mails
+in an easy way.
+
+Usage:
+- Generate the patch with git format-patch.
+- Start writing a new e-mail in Thunderbird.
+- Press the external editor button (or Ctrl-E) to run appp.sh
+- Select the previosly generated patch file.
+- Finish editing the e-mail.
+
+Any text that is entered into the message editor before appp.sh is called
+will be moved to the section between the --- and the diffstat.
+
+All S-O-B:s and Cc:s in the patch will be added to the CC list.
+
+To set it up, just install External Editor and tell it to use appp.sh as the
+editor.
+
+Zenity is a required dependency.

+
+Projects list file format
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instead of having gitweb find repositories by scanning filesystem starting
+from $projectroot (or $projects_list, if it points to directory), you can
+provide list of projects by setting $projects_list to a text file with list
+of projects (and some additional info). This file uses the following
+format:
+
+One record (for project / repository) per line, whitespace separated fields;
+does not support (at least for now) lines continuation (newline escaping).
+Leading and trailing whitespace are ignored, any run of whitespace can be
+used as field separator (rules for Perl's "split(' ', $line)"). Keyed by
+the first field, which is project name, i.e. path to repository GIT_DIR
+relative to $projectroot. Fields use modified URI encoding, defined in
+RFC 3986, section 2.1 (Percent-Encoding), or rather "Query string encoding"
+(see http://en.wikipedia.org/wiki/Query_string#URL_encoding), the difference
+being that SP (' ') can be encoded as '+' (and therefore '+' has to be also
+percent-encoded). Reserved characters are: '%' (used for encoding), '+'
+(can be used to encode SPACE), all whitespace characters as defined in Perl,
+including SP, TAB and LF, (used to separate fields in a record).
+
+Currently list of fields is
+ * <repository path> - path to repository GIT_DIR, relative to $projectroot
+ * <repository owner> - displayed as repository owner, preferably full name,
+ or email, or both
+
+You can additionally use $projects_list file to limit which repositories
+are visible, and together with $strict_export to limit access to
+repositories (see "Gitweb repositories" section in gitweb/INSTALL).

+=item remote_refs ( REPOSITORY [, GROUPS [, REFGLOBS ] ] )
+
+This function returns a hashref of refs stored in a given remote repository.
+The hash is in the format C<refname =\> hash>. For tags, the C<refname> entry
+contains the tag object while a C<refname^{}> entry gives the tagged objects.
+
+C<REPOSITORY> has the same meaning as the appropriate C<git-ls-remote>
+argument; either an URL or a remote name (if called on a repository instance).
+C<GROUPS> is an optional arrayref that can contain 'tags' to return all the
+tags and/or 'heads' to return all the heads. C<REFGLOB> is an optional array
+of strings containing a shell-like glob to further limit the refs returned in
+the hash; the meaning is again the same as the appropriate C<git-ls-remote>
+argument.
+
+This function may or may not be called on a repository instance. In the former
+case, remote names as defined in the repository are recognized as repository
+specifiers.

This causes the test to immediately exit upon the first
failed test.
+--long-tests::
+ This causes additional long-running tests to be run (where
+ available), for more exhaustive testing.
+
+
+Skipping Tests
+--------------
+
+In some environments, certain tests have no way of succeeding
+due to platform limitation, such as lack of 'unzip' program, or
+filesystem that do not allow arbitrary sequence of non-NUL bytes
+as pathnames.
+
+You should be able to say something like
+
+ $ GIT_SKIP_TESTS=t9200.8 sh ./t9200-git-cvsexport-commit.sh
+
+and even:
+
+ $ GIT_SKIP_TESTS='t[0-4]??? t91?? t9200.8' make
+
+to omit such tests. The value of the environment variable is a
+SP separated list of patterns that tells which tests to skip,
+and either can match the "t[0-9]{4}" part to skip the whole
+test, or t[0-9]{4} followed by ".$number" to say which
+particular test to skip.
+
+Note that some tests in the existing test suite rely on previous
+test item, so you cannot arbitrarily disable one and expect the
+remainder of test to check what the test originally was intended
+to check.

-################################################################
-
-This sample hook safeguards topic branches that have been
-published from being rewound.
-
-The workflow assumed here is:
-
- * Once a topic branch forks from "master", "master" is never
- merged into it again (either directly or indirectly).
-
- * Once a topic branch is fully cooked and merged into "master",
- it is deleted. If you need to build on top of it to correct
- earlier mistakes, a new topic branch is created by forking at
- the tip of the "master". This is not strictly necessary, but
- it makes it easier to keep your history simple.
-
- * Whenever you need to test or publish your changes to topic
- branches, merge them into "next" branch.
-
-The script, being an example, hardcodes the publish branch name
-to be "next", but it is trivial to make it configurable via
-$GIT_DIR/config mechanism.
-
-With this workflow, you would want to know:
-
-(1) ... if a topic branch has ever been merged to "next". Young
- topic branches can have stupid mistakes you would rather
- clean up before publishing, and things that have not been
- merged into other branches can be easily rebased without
- affecting other people. But once it is published, you would
- not want to rewind it.
-
-(2) ... if a topic branch has been fully merged to "master".
- Then you can delete it. More importantly, you should not
- build on top of it -- other people may already want to
- change things related to the topic as patches against your
- "master", so if you need further changes, it is better to
- fork the topic (perhaps with the same name) afresh from the
- tip of "master".
-
-Let's look at this example:
-
- o---o---o---o---o---o---o---o---o---o "next"
- / / / /
- / a---a---b A / /
- / / / /
- / / c---c---c---c B /
- / / / \ /
- / / / b---b C \ /
- / / / / \ /
- ---o---o---o---o---o---o---o---o---o---o---o "master"
-
-
-A, B and C are topic branches.
-
- * A has one fix since it was merged up to "next".
-
- * B has finished. It has been fully merged up to "master" and "next",
- and is ready to be deleted.
-
- * C has not merged to "next" at all.
-
-We would want to allow C to be rebased, refuse A, and encourage
-B to be deleted.
-
-To compute (1):
-
- git-rev-list ^master ^topic next
- git-rev-list ^master next
-
- if these match, topic has not merged in next at all.
-
-To compute (2):
-
- git-rev-list master..topic
-
- if this is empty, it is fully merged to "master".

+################################################################
+
+This sample hook safeguards topic branches that have been
+published from being rewound.
+
+The workflow assumed here is:
+
+ * Once a topic branch forks from "master", "master" is never
+ merged into it again (either directly or indirectly).
+
+ * Once a topic branch is fully cooked and merged into "master",
+ it is deleted. If you need to build on top of it to correct
+ earlier mistakes, a new topic branch is created by forking at
+ the tip of the "master". This is not strictly necessary, but
+ it makes it easier to keep your history simple.
+
+ * Whenever you need to test or publish your changes to topic
+ branches, merge them into "next" branch.
+
+The script, being an example, hardcodes the publish branch name
+to be "next", but it is trivial to make it configurable via
+$GIT_DIR/config mechanism.
+
+With this workflow, you would want to know:
+
+(1) ... if a topic branch has ever been merged to "next". Young
+ topic branches can have stupid mistakes you would rather
+ clean up before publishing, and things that have not been
+ merged into other branches can be easily rebased without
+ affecting other people. But once it is published, you would
+ not want to rewind it.
+
+(2) ... if a topic branch has been fully merged to "master".
+ Then you can delete it. More importantly, you should not
+ build on top of it -- other people may already want to
+ change things related to the topic as patches against your
+ "master", so if you need further changes, it is better to
+ fork the topic (perhaps with the same name) afresh from the
+ tip of "master".
+
+Let's look at this example:
+
+ o---o---o---o---o---o---o---o---o---o "next"
+ / / / /
+ / a---a---b A / /
+ / / / /
+ / / c---c---c---c B /
+ / / / \ /
+ / / / b---b C \ /
+ / / / / \ /
+ ---o---o---o---o---o---o---o---o---o---o---o "master"
+
+
+A, B and C are topic branches.
+
+ * A has one fix since it was merged up to "next".
+
+ * B has finished. It has been fully merged up to "master" and "next",
+ and is ready to be deleted.
+
+ * C has not merged to "next" at all.
+
+We would want to allow C to be rebased, refuse A, and encourage
+B to be deleted.
+
+To compute (1):
+
+ git-rev-list ^master ^topic next
+ git-rev-list ^master next
+
+ if these match, topic has not merged in next at all.
+
+To compute (2):
+
+ git-rev-list master..topic
+
+ if this is empty, it is fully merged to "master".
