Based on its name, people may read the 'git revert' documentation when
they want to undo local changes, especially people who have used other

provides several other ways to undo changes to files. We can help
them by pointing them towards the git commands that do what they might
want to do.

"git-merge" is a binary executable these days, and looking for assignment
to $all_strategies variable with grep/sed does not work well.
When asked for an unknown strategy, pre-1.6.0 and post-1.6.0 "git merge"
commands respectively say:
$ $HOME/git-snap-v1.5.6.5/bin/git merge -s help
available strategies are: recur recursive octopus resolve stupid ours subtree
$ $HOME/git-snap-v1.6.0/bin/git merge -s help
Could not find merge strategy 'help'.
Available strategies are: recursive octopus resolve ours subtree.
both on their standard error stream. We can use this to learn what
strategies are supported.
The sed script is written in such a way that it catches both old and new
message styles ("Available" vs "available", and the full stop at the end).
It also allows future versions of "git merge" to line-wrap the list of
strategies, and add extra comments, like this:
$ $HOME/git-snap-v1.6.1/bin/git merge -s help
Could not find merge strategy 'help'.
Available strategies are: blame recursive octopus resolve ours
subtree.
Also you have custom strategies: theirs
Make sure you spell strategy names correctly.

The code remembered that the last diff output it saw was an empty line,
and tried to reset that state whenever it sees a context line, a non-blank
new line, or a new hunk. However, this codepath asks the underlying diff
engine to feed diff without any context, and the "just saw an empty line"
state was not reset if you added a new blank line in the last hunk of your
patch, even if it is not the last line of the file.

In handle_from, we calculate the end boundary of a section
to remove from a strbuf using strcspn like this:
el = strcspn(buf, set_of_end_boundaries);
strbuf_remove(&sb, start, el + 1);
This works fine if "el" is the offset of the boundary
character, meaning we remove up to and including that
character. But if the end boundary didn't match (that is, we
hit the end of the string as the boundary instead) then we
want just "el". Asking for "el+1" caught an out-of-bounds
assertion in the strbuf library.
This manifested itself when we got a 'From' header that had
just an email address with nothing else in it (the end of
the string was the end of the address, rather than, e.g., a
trailing '>' character), causing git-mailinfo to barf.

Recent changes to is_multipart_boundary() caused git-mailinfo to segfault.
The reason was after handling the end of the boundary the code tried to look
for another boundary. Because the boundary list was empty, dereferencing
the pointer to the top of the boundary caused the program to go boom.
The fix is to check to see if the list is empty and if so go on its merry
way instead of looking for another boundary.
I also fixed a couple of increments and decrements that didn't look correct
relating to content_top.
The boundary test case was updated to catch future problems like this again.

"git stash -h" showed some incomplete and ugly usage information.
For example, the useful "--keep-index" option for "save" or the "--index"
option for "apply" were not shown. Also in the documentation synopsis they
were not shown, so that there is no incentive to scroll down and even see
that such options exist.
This patch improves the git-stash synopsis in the documentation by
mentioning that further options to the stash commands and then copies
this synopsis to the usage information string of git-stash.sh.
For the latter, the dashless git command string has to be inserted on the
second and the following usage lines. The code of this is taken from
git-sh-setup so that all lines will show the command string.
Note that the "create" command is not advertised at all now, because

test-chmtime can adjust the mtime of a file based on the file's mtime, or
based on the system time. For files accessed over NFS, the file's mtime is
set by the NFS server, and as such may vary a great deal from the NFS
client's system time if the clocks of the client and server are out of
sync. Since these tests are testing the expire feature of git-prune, an
incorrect mtime could cause a file to be expired or not expired incorrectly
and produce a test failure.
Avoid this NFS pitfall by modifying the calls to test-chmtime so that the
mtime is adjusted based on the system time, rather than the file's mtime.

* git://git.bogomips.org/git-svn:
git-svn: Reduce temp file usage when dealing with non-links
git-svn: Make it incrementally faster by minimizing temp files
Git.pm: Add faculties to allow temp files to be cached
Currently, in sub 'close_file', git-svn creates a temporary file and
copies the contents of the blob to be written into it. This is useful
for symlinks because svn stores symlinks in the form:
link $FILE_PATH
Git creates a blob only out of '$FILE_PATH' and uses file mode to
indicate that the blob should be interpreted as a symlink.
As git-hash-object is invoked with --stdin-paths, a duplicate of the
link from svn must be created that leaves off the first five bytes,
i.e. 'link '. However, this is wholly unnecessary for normal blobs,
though, as we already have a temp file with their contents. Copying
the entire file gains nothing, and effectively requires a file to be
written twice before making it into the object db.
This patch corrects that issue, holding onto the substr-like
duplication for symlinks, but skipping it altogether for normal blobs
by reusing the existing temp file.
Signed-off-by: Marcus Griep <marcus@griep.us>
Acked-by: Eric Wong <normalperson@yhbt.net>
Currently, git-svn would create a temp file on four occasions:
1. Reading a blob out of the object db
2. Creating a delta from svn
3. Hashing and writing a blob into the object db
4. Reading a blob out of the object db (in another place in code)
Any time git-svn did the above, it would dutifully create and then
delete said temp file. Unfortunately, this means that between 2-4
temporary files are created/deleted per file 'add/modify'-ed in
svn (O(n)). This causes significant overhead and helps the inode
counter to spin beautifully.
By its nature, git-svn is a serial beast. Thus, reusing a temp file
does not pose significant problems. "truncate and seek" takes much
less time than "unlink and create". This patch centralizes the
tempfile creation and holds onto the tempfile until they are deleted
on exit. This significantly reduces file overhead, now requiring
at most three (3) temp files per run (O(1)).

This patch offers a generic interface to allow temp files to be
cached while using an instance of the 'Git' package. If many
temp files are created and destroyed during the execution of a
program, this caching mechanism can help reduce the amount of
files created and destroyed by the filesystem.
The temp_acquire method provides a weak guarantee that a temp
file will not be stolen by subsequent requests. If a file is
locked when another acquire request is made, a simple error is
thrown.
