"git checkout -" is a short-hand for "git checkout @{-1}" and the
"@{nth}" notation for a negative number is to find nth previous
checkout in the reflog of the HEAD to determine the name of the
branch the user was on. We would want to find the nth most recent
reflog entry that matches "checkout: moving from X to Y" for this.
Unfortunately, reflog is implemented as an append-only file, and the
API to iterate over its entries, for_each_reflog_ent(), reads the
file in order, giving the entries from the oldest to newer. For the
purpose of finding nth most recent one, this API forces us to record
the last n entries in a rotating buffer and give the result out only
after we read everything. To optimize for a common case of finding
the nth most recent one for a small value of n, we also have a side
API for_each_recent_reflog_ent() that starts reading near the end of
the file, but it still has to read the entries in the "wrong" order.
The implementation of understanding @{-1} uses this interface.
This all becomes unnecessary if we add an API to let us iterate over
reflog entries in the reverse order, from the newest to older.

We describe what gets pushed by default when the command line does
not give any <refspec> under the bullet point of <refspec>.
It is a bit unfriendly to expect users to read on <refspec> when
they are not giving any in the first place. "What gets pushed" is
determined by taking many factors (<refspec> argument being only one
of them) into account, and is a property of the entire command, not
an individual argument. Also we do not describe "Where the push
goes" when the command line does not say.
Give the description on "what gets pushed to where" upfront before
explaining individual arguments and options.
Also update the description of <refspec> to say what it is, what it
is used for, before explaining what shape it takes.

We keep a static array of variables that should be cleared
when invoking a sub-process on another repo. We statically
size the array with the LOCAL_REPO_ENV_SIZE macro so that
any readers do not have to count it themselves.
As it turns out, no readers actually use the macro, and it
creates a maintenance headache, as modifications to the
array need to happen in two places (one to add the new
element, and another to bump the size).
Since it's NULL-terminated, we can just drop the size macro
entirely. While we're at it, we'll clean up some comments
around it, and add a new mention of it at the top of the
list of environment variable macros. Even though
local_repo_env is right below that list, it's easy to miss,
and additions to that list should consider local_repo_env.

See http://www.open.collab.net/community/subversion/articles/merge-info.html
Extract:
The range r30430:30435 that was added to 1.5.x in this merge has a '*' suffix for 1.5.x\www.
This '*' is the marker for a non-inheritable mergeinfo range.
The '*' means that only the path on which the mergeinfo is explicitly set has had this range merged into it.

by non-absolute paths, like the value of the P4CONFIG environment

A more informative message for "complete" bundles was added in commit
8c3710fd30 (tweak "bundle verify" of a complete history, 2012-06-04).
However, the prerequisites ref list is currently read *after* we
check if it equals zero, which means we never actually use the
number of prerequisite refs to decide when to print the newly
introduced message. The code incorrectly uses the number of
references recorded in the bundle instead.

The new option "--follow-tags" tells "git push" to push annotated
tags that are missing from the other side and that can be reached by
the history that is otherwise pushed out.
For example, if you are using the "simple", "current", or "upstream"
push, you would ordinarily push the history leading to the commit at
your current HEAD and nothing else. With this option, you would
also push all annotated tags that can be reached from that commit to

With "git submodule init" the user is able to tell git he cares about one
or more submodules and wants to have it populated on the next call to "git
submodule update". But currently there is no easy way he could tell git he
does not care about a submodule anymore and wants to get rid of his local
work tree (except he knows a lot about submodule internals and removes the
"submodule.$name.url" setting from .git/config together with the work tree
himself).
Help those users by providing a 'deinit' command. This removes the
whole submodule.<name> section from .git/config (either for the given
submodule(s) or for all those which have been initialized if '.' is used)
together with their work tree. Fail if the current work tree contains
modifications (unless forced), but don't complain when either the work
tree is already removed or no settings are found in .git/config.
Add tests and link the man pages of "git submodule deinit" and "git rm"
to assist the user in deciding whether removing or unregistering the
submodule is the right thing to do for him. Also add the deinit subcommand
to the completion list.

A maildir does not technically record the order in which
items were placed into it. That means that when applying a
patch series from a maildir, we may get the patches in the
wrong order. We try to work around this by sorting the
filenames. Unfortunately, this may or may not work depending
on the naming scheme used by the writer of the maildir.
For instance, mutt will write:
${epoch_seconds}.${pid}_${seq}.${host}
where we have:
- epoch_seconds: timestamp at which entry was written
- pid: PID of writing process
- seq: a sequence number to ensure uniqueness of filenames
- host: hostname
None of the numbers are zero-padded. Therefore, when we sort
the names as byte strings, entries that cross a digit
boundary (e.g., 10) will sort out of order. In the case of
timestamps, it almost never matters (because we do not cross
a digit boundary in the epoch time very often these days).
But for the sequence number, a 10-patch series would be
ordered as 1, 10, 2, 3, etc.
To fix this, we can use a custom sort comparison function
which traverses each string, comparing chunks of digits
numerically, and otherwise doing a byte-for-byte comparison.
That would sort:
123.456_1.bar
123.456_2.bar
...
123.456_10.bar
according to the sequence number. Since maildir does not
define a filename format, this is really just a heuristic.
But it happens to work for mutt, and there is a reasonable
chance that it will work for other writers, too (at least as
well as a straight sort).

Before 82dce99 (attr: more matching optimizations from .gitignore,
2012-10-15), .gitattributes did not have any special treatment of a
leading '!'. The docs, however, always said
The rules how the pattern matches paths are the same as in
`.gitignore` files; see linkgit:gitignore[5].
By those rules, leading '!' means pattern negation. So 82dce99
correctly determined that this kind of line makes no sense and should
be disallowed.
However, users who actually had a rule for files starting with a '!'
are in a bad position: before 82dce99 '!' matched that literal
character, so it is conceivable that users have .gitattributes with
such lines in them. After 82dce99 the unescaped version was
disallowed in such a way that git outright refuses to run(!) most
commands in the presence of such a .gitattributes. It therefore
becomes very hard to fix, let alone work with, such repositories.
Let's at least allow the users to fix their repos: change the fatal
error into a warning.

user-manual: Reorganize the reroll sections, adding 'git rebase -i'
The logic to limit the refs used for describing with a matching pattern
with --match=<pattern> parameter was implemented incorrectly when --all
is in effect. It just demoted a ref that did not match the pattern to
lower priority---if there aren't other refs with higher priority
that describe the given commit, such an unmatching ref was still used.
When --match is used, reject refs that do not match the given
criteria, so that with or without --all, the output will only use
refs that match the pattern.

Currently ZIP archive entries of files with export-subst attribute are
broken if they are stored uncompressed.
We get the size of a file from sha1_object_info(), but this number is
likely wrong for files whose contents are changed due to export-subst
placeholder expansion. We use sha1_file_to_archive() to get the
expanded file contents and size in that case. We proceed to use that
size for the uncompressed size field (good), but the compressed size
field is set based on the size from sha1_object_info() (bad).
This matters only for uncompressed files because for deflated files
we use the correct value after compression is done. And for files
without export-subst expansion the sizes from sha1_object_info() and
sha1_file_to_archive() are the same, so they are unaffected as well.
This patch fixes the issue by setting the compressed size based on the
uncompressed size only after we actually know the latter.
Also make use of the test file substfile1 to check for the breakage;
it was only stored verbatim so far. For that purpose, set the
attribute export-subst and replace its contents with the expected
expansion after committing.
