Git Release Notes

Fixes since v1.7.12

 * "git apply -p0" did not parse pathnames on "diff --git" line
   correctly.  This caused patches that had pathnames in no other
   places to be mistakenly rejected (most notably, binary patch that
   does not rename nor change mode).  Textual patches, renames or mode
   changes have preimage and postimage pathnames in different places
   in a form that can be parsed unambiguously and did not suffer from
   this problem.

 * "git cherry-pick A C B" used to replay changes in A and then B and
   then C if these three commits had committer timestamps in that
   order, which is not what the user who said "A C B" naturally

 * "git commit --amend" let the user edit the log message and then
   died when the human-readable committer name was given
   insufficiently by getpwent(3).

 * Some capabilities were asked by fetch-pack even when upload-pack
   did not advertise that they are available.  fetch-pack has been
   fixed not to do so.

 * "git diff" had a confusion between taking data from a path in the
   working tree and taking data from an object that happens to have
   name 0{40} recorded in a tree.

 * "git for-each-ref" did not correctly support more than one --sort

 * "git log .." errored out saying it is both rev range and a path
   when there is no disambiguating "--" is on the command line.
   Update the command line parser to interpret ".." as a path in such
   a case.

 * The "--topo-order", "--date-order" (and the lack of either means
   the default order) options to "rev-list" and "log" family of
   commands were poorly described in the documentation.

 * "git prune" without "-v" used to warn about leftover temporary
   files (which is an indication of an earlier aborted operation).

 * Pushing to smart HTTP server with recent Git fails without having
   the username in the URL to force authentication, if the server is
   configured to allow GET anonymously, while requiring authentication
   for POST.

 * The reflog entries left by "git rebase" and "git rebase -i" were
   inconsistent (the interactive one gave an abbreviated object name).

 * When "git push" triggered the automatic gc on the receiving end, a
   message from "git prune" that said it was removing cruft leaked to
   the standard output, breaking the communication protocol.

 * "git show --quiet" ought to be a synonym for "git show -s", but

 * "git show --format='%ci'" did not give timestamp correctly for
   commits created without human readable name on "committer" line.

 * "git send-email" did not unquote encoded words that appear on the
   header correctly, and lost "_" from strings.

 * The interactive prompt "git send-email" gives was error prone. It
   asked "What e-mail address do you want to use?" with the address it
   guessed (correctly) the user would want to use in its prompt,
   tempting the user to say "y". But the response was taken as "No,
   please use 'y' as the e-mail address instead", which is most
   certainly not what the user meant.

 * "gitweb" when used with PATH_INFO failed to notice directories with
   SP (and other characters that need URL-style quoting) in them.

 * When the user gives an argument that can be taken as both a
   revision name and a pathname without disambiguating with "--", we
   used to give a help message "Use '--' to separate".  The message
   has been clarified to show where that '--' goes on the command

 * When the user exports a non-default IFS without HT, scripts that
   rely on being able to parse "ls-files -s | while read a b c..."
   started to fail.  Protect them from such a misconfiguration.

 * The attribute system may be asked for a path that itself or its
   leading directories no longer exists in the working tree, and it is
   fine if we cannot open .gitattribute file in such a case.  Failure
   to open per-directory .gitattributes with error status other than
   ENOENT and ENOTDIR should be diagnosed, but it wasn't.

 * After "gitk" showed the contents of a tag, neither "Reread
   references" nor "Reload" did not update what is shown as the
   contents of it, when the user overwrote the tag with "git tag -f".

 * "ciabot" script (in contrib/) has been updated with extensive

 * "git-jump" script (in contrib/) did not work well when
   diff.noprefix or diff.mnemonicprefix is in effect.

 * Older parts of the documentation described as if having a regular
   file in .git/refs/ hierarchy were the only way to have branches and
   tags, which is not true for quite some time.

 * A utility shell function test_seq has been added as a replacement
   for the 'seq' utility found on some platforms.

 * Compatibility wrapper to learn the maximum number of file
   descriptors we can open around sysconf(_SC_OPEN_MAX) and
   getrlimit(RLIMIT_NO_FILE) has been introduced for portability.

 * We used curl_easy_strerror() without checking version of cURL,
   breaking the build for versions before curl 7.12.0.

 * Code to work around MacOS X UTF-8 gotcha has been cleaned up.

 * Fallback 'getpass' implementation made unportable use of stdio API.

 * The "--rebase" option to "git pull" can be abbreviated to "-r",
   but we didn't document it.

 * It was generally understood that "--long-option"s to many of our
   subcommands can be abbreviated to the unique prefix, but it was not
   easy to find it described for new readers of the documentation set.

 * The synopsis said "checkout [-B branch]" to make it clear the
   branch name is a parameter to the option, but the heading for the
   option description was "-B::", not "-B branch::", making the
   documentation misleading.

Also contains numerous documentation updates.
