+Git v2.6.4 Release Notes
+========================
+
+Fixes since v2.6.3
+------------------
+
+ * The "configure" script did not test for -lpthread correctly, which
+ upset some linkers.
+
+ * Add support for talking http/https over socks proxy.
+
+ * Portability fix for Windows, which may rewrite $SHELL variable using
+ non-POSIX paths.
+
+ * We now consistently allow all hooks to ignore their standard input,
+ rather than having git complain of SIGPIPE.
+
+ * Fix shell quoting in contrib script.
+
+ * Test portability fix for a topic in v2.6.1.
+
+ * Allow tilde-expansion in some http config variables.
+
+ * Give a useful special case "diff/show --word-diff-regex=." as an
+ example in the documentation.
+
+ * Fix for a corner case in filter-branch.
+
+ * Make git-p4 work on a detached head.
+
+ * Documentation clarification for "check-ignore" without "--verbose".
+
+ * Just like the working tree is cleaned up when the user cancelled
+ submission in P4Submit.applyCommit(), clean up the mess if "p4
+ submit" fails.
+
+ * Having a leftover .idx file without corresponding .pack file in
+ the repository hurts performance; "git gc" learned to prune them.
+
+ * The code to prepare the working tree side of temporary directory
+ for the "dir-diff" feature forgot that symbolic links need not be
+ copied (or symlinked) to the temporary area, as the code already
+ special cases and overwrites them. Besides, it was wrong to try
+ computing the object name of the target of symbolic link, which may
+ not even exist or may be a directory.
+
+ * There was no way to defeat a configured rebase.autostash variable
+ from the command line, as "git rebase --no-autostash" was missing.
+
+ * Allow "git interpret-trailers" to run outside of a Git repository.
+
+ * Produce correct "dirty" marker for shell prompts, even when we
+ are on an orphan or an unborn branch.
+
+ * Some corner cases have been fixed in string-matching done in "git
+ status".
+
+ * Apple's common crypto implementation of SHA1_Update() does not take
+ more than 4GB at a time, and we now have a compile-time workaround
+ for it.
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.

+Git v2.6.5 Release Notes
+========================
+
+Fixes since v2.6.4
+------------------
+
+ * Because "test_when_finished" in our test framework queues the
+ clean-up tasks to be done in a shell variable, it should not be
+ used inside a subshell. Add a mechanism to allow 'bash' to catch
+ such uses, and fix the ones that were found.
+
+ * Update "git subtree" (in contrib/) so that it can take whitespaces
+ in the pathnames, not only in the in-tree pathname but the name of
+ the directory that the repository is in.
+
+ * Cosmetic improvement to lock-file error messages.
+
+ * mark_tree_uninteresting() has code to handle the case where it gets
+ passed a NULL pointer in its 'tree' parameter, but the function had
+ 'object = &tree->object' assignment before checking if tree is
+ NULL. This gives a compiler an excuse to declare that tree will
+ never be NULL and apply a wrong optimization. Avoid it.
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.
* Prepare for Git on-disk repository representation to undergo
backward incompatible changes by introducing a new repository
format version "1", with an extension mechanism.
- (merge 067fbd4 jk/repository-extension later to maint).
* "git worktree" learned a "list" subcommand.
a superset of "--no-progress". Extend the command to support the
usual "--[no-]progress".
+ * The semantics of tranfer.hideRefs configuration variable have been
+ extended to work better with the ref "namespace" feature that lets
+ you throw unrelated bunches of repositories in a single physical
+ repository and virtually serve them as separate ones.
+
+ * send-email config variables whose values are pathnames now go
+ through the ~username/ expansion.
+
+ * bash completion learnt to TAB-complete recipient addresses given
+ to send-email.
+
+ * The credential-cache daemon can be told to ignore SIGHUP to work
+ around issue when running Git from inside emacs.
+
Performance, Internal Implementation, Development Support etc.
clean-up tasks to be done in a shell variable, it should not be
used inside a subshell. Add a mechanism to allow 'bash' to catch
such uses, and fix the ones that were found.
- (merge 0968f12 jk/test-lint-forbid-when-finished-in-subshell later to maint).
* The debugging infrastructure for pkt-line based communication has
been improved to mark the side-band communication specifically.
* The internal stripspace() function has been moved to where it
logically belongs to, i.e. strbuf API, and the command line parser
of "git stripspace" has been updated to use the parse_options API.
- (merge bed4452 tk/stripspace later to maint).
* "git am" used to spawn "git mailinfo" via run_command() API once
per each patch, but learned to make a direct call to mailinfo()
* With a "debug" helper, debugging of a single "git" invocation in
our test scripts has become a lot easier.
+ * The "configure" script did not test for -lpthread correctly, which
+ upset some linkers.
+
+ * Cross completed task off of subtree project's todo list.
+
+ * Test cleanups for the subtree project.
+
+ * Clean up style in an ancient test t9300.
+
+ * Work around some test flakiness with p4d.
+
+ * Fsck did not correctly detect a NUL-truncated header in a tag.
+
+ * Use a safer behavior when we hit errors verifying remote certificates.
+
+ * Speed up filter-branch for cases where we only care about rewriting
+ commits, not tree data.
+
+ * The parse-options API has been updated to make "-h" command line
+ option work more consistently in all commands.
+
+ * "git svn rebase/mkdirs" got optimized by keeping track of empty
+ directories better.
+
+ * Fix some racy client/server tests by treating SIGPIPE the same as a
+ normal non-zero exit.
+
+ * The necessary infrastructure to build topics using the free Travis
+ CI has been added. Developers forking from this topic (and enabling
+ Travis) can do their own builds, and we can turn on auto-builds for
+ git/git (including build-status for pull requests that people
+ open).
+
Also contains various documentation updates and code clean-ups.
(which is not a great UI element as they can only appear at the end
of the command line). Add notice to documentation of each and
every one of them.
- (merge 2b594bf mm/keyid-docs later to maint).
* "git blame --first-parent v1.0..v2.0" was not rejected but did not
limit the blame to commits on the first parent chain.
- (merge 95a4fb0 jk/blame-first-parent later to maint).
* "git subtree" (in contrib/) now can take whitespaces in the
pathnames, not only in the in-tree pathname but the name of the
- directory that the repository is in. (merge 5b6ab38
- as/subtree-with-spaces later to maint).
+ directory that the repository is in.
* The ssh transport, just like any other transport over the network,
did not clear GIT_* environment variables, but it is possible to
use SendEnv and AcceptEnv to leak them to the remote invocation of
Git, which is not a good idea at all. Explicitly clear them just
like we do for the local transport.
- (merge a48b409 jk/connect-clear-env later to maint).
* Correct "git p4 --detect-labels" so that it does not fail to create
a tag that points at a commit that is also being imported.
- (merge b43702a ld/p4-import-labels later to maint).
* The Makefile always runs the library archiver with hardcoded "crs"
options, which was inconvenient for exotic platforms on which
people want to use programs with totally different set of command
line options.
- (merge ac179b4 jw/make-arflags-customizable later to maint).
* Customization to change the behaviour with "make -w" and "make -s"
in our Makefile was broken when they were used together.
- (merge ef49e05 jk/make-findstring-makeflags-fix later to maint).
* Allocation related functions and stdio are unsafe things to call
inside a signal handler, and indeed killing the pager can cause
glibc to deadlock waiting on allocation mutex as our signal handler
tries to free() some data structures in wait_for_pager(). Reduce
these unsafe calls.
- (merge 507d780 ti/glibc-stdio-mutex-from-signal-handler later to maint).
* The way how --ref/--notes to specify the notes tree reference are
DWIMmed was not clearly documented.
- (merge e14c92e jk/notes-dwim-doc later to maint).
* "git gc" used to barf when a symbolic ref has gone dangling
(e.g. the branch that used to be your upstream's default when you
cloned from it is now gone, and you did "fetch --prune").
- (merge 14886b4 js/gc-with-stale-symref later to maint).
* "git clone --dissociate" runs a big "git repack" process at the
end, and it helps to close file descriptors that are open on the
packs and their idx files before doing so on filesystems that
cannot remove a file that is still open.
- (merge 786b150 js/clone-dissociate later to maint).
* Description of the "log.follow" configuration variable in "git log"
documentation is now also copied to "git config" documentation.
- (merge fd8d07e dt/log-follow-config later to maint).
* "git rebase -i" had a minor regression recently, which stopped
considering a line that begins with an indented '#' in its insn
Windows where CRLF left by the editor is turned into a trailing CR
on the line read via the "read" built-in command of bash. Both of
these issues are now fixed.
- (merge 39743cf gr/rebase-i-drop-warn later to maint).
* After "git checkout --detach", "git status" reported a fairly
useless "HEAD detached at HEAD", instead of saying at which exact
commit.
- (merge 0eb8548 mm/detach-at-HEAD-reflog later to maint).
* When "git send-email" wanted to talk over Net::SMTP::SSL,
Net::Cmd::datasend() did not like to be fed too many bytes at the
same time and failed to send messages. Send the payload one line
at a time to work around the problem.
- (merge f60c483 sa/send-email-smtp-batch-data-limit later to maint).
* When "git am" was rewritten as a built-in, it stopped paying
attention to user.signingkey, which was fixed.
- (merge 434c64d pt/am-builtin later to maint).
* It was not possible to use a repository-lookalike created by "git
worktree add" as a local source of "git clone".
- (merge d78db84 nd/clone-linked-checkout later to maint).
* On a case insensitive filesystems, setting GIT_WORK_TREE variable
using a random cases that does not agree with what the filesystem
thinks confused Git that it wasn't inside the working tree.
- (merge 63ec5e1 js/icase-wt-detection later to maint).
* Performance-measurement tests did not work without an installed Git.
- (merge 31cd128 sb/perf-without-installed-git later to maint).
* A test script for the HTTP service had a timing dependent bug,
which was fixed.
- (merge 362d8b6 sb/http-flaky-test-fix later to maint).
* There were some classes of errors that "git fsck" diagnosed to its
standard error that did not cause it to exit with non-zero status.
- (merge 122f76f jc/fsck-dropped-errors later to maint).
* Work around "git p4" failing when the P4 depot records the contents
in UTF-16 without UTF-16 BOM.
- (merge 1f5f390 ls/p4-translation-failure later to maint).
* When "git gc --auto" is backgrounded, its diagnosis message is
lost. Save it to a file in $GIT_DIR and show it next time the "gc
--auto" is run.
- (merge 329e6e8 nd/gc-auto-background-fix later to maint).
* The submodule code has been taught to work better with separate
work trees created via "git worktree add".
- (merge 11f9dd7 mk/submodule-gitdir-path later to maint).
* "git gc" is safe to run anytime only because it has the built-in
grace period to protect young objects. In order to run with no
grace period, the user must make sure that the repository is
quiescent.
- (merge fae1a90 jc/doc-gc-prune-now later to maint).
* A recent "filter-branch --msg-filter" broke skipping of the commit
object header, which is fixed.
- (merge a5a4b3f jk/filter-branch-use-of-sed-on-incomplete-line later to maint).
* The normalize_ceiling_entry() function does not muck with the end
of the path it accepts, and the real world callers do rely on that,
but a test insisted that the function drops a trailing slash.
- (merge b2a7123 rd/test-path-utils later to maint).
* A test for interaction between untracked cache and sparse checkout
added in Git 2.5 days were flaky.
- (merge 9b680fb dt/t7063-fix-flaky-test later to maint).
* A couple of commands still showed "[options]" in their usage string
to note where options should come on their command line, but we
spell that "[<options>]" in most places these days.
- (merge d96a031 rt/placeholder-in-usage later to maint).
* The synopsis text and the usage string of subcommands that read
list of things from the standard input are often shown as if they
only take input from a file on a filesystem, which was misleading.
- (merge 33e8fc8 jc/usage-stdin later to maint).
* "git am -3" had a small regression where it is aborted in its error
handling codepath when underlying merge-recursive failed in certain
ways, as it assumed that the internal call to merge-recursive will
never die, which is not the case (yet).
- (merge c63d4b2 jc/am-3-fallback-regression-fix later to maint).
* The linkage order of libraries was wrong in places around libcurl.
- (merge 7e91e8d rp/link-curl-before-ssl later to maint).
* The name-hash subsystem that is used to cope with case insensitive
filesystems keeps track of directories and their on-filesystem
cache entry was removed from the index, leading to use after free.
This was fixed by recording the path for each directory instead of
borrowing cache entries and restructuring the API somewhat.
- (merge 41284eb dt/name-hash-dir-entry-fix later to maint).
* "git merge-file" tried to signal how many conflicts it found, which
obviously would not work well when there are too many of them.
- (merge e34f802 jk/merge-file-exit-code later to maint).
* The error message from "git blame --contents --reverse" incorrectly
talked about "--contents --children".
- (merge 9526197 mk/blame-error-message later to maint).
* "git imap-send" did not compile well with older version of cURL library.
- (merge 71d9257 js/imap-send-curl-compilation-fix later to maint).
* Merging a branch that removes a path and another that changes the
mode bits on the same path should have conflicted at the path, but
it didn't and silently favoured the removal.
- (merge 72fac66 jk/delete-modechange-conflict later to maint).
* "git --literal-pathspecs add -u/-A" without any command line
argument misbehaved ever since Git 2.0.
- (merge 29abb33 jc/add-u-A-default-to-top later to maint).
* "git daemon" uses "run_command()" without "finish_command()", so it
needs to release resources itself, which it forgot to do.
- (merge b1b49ff rs/daemon-plug-child-leak later to maint).
* "git status --branch --short" accessed beyond the constant string
"HEAD", which has been corrected.
- (merge c72b49d rs/wt-status-detached-branch-fix later to maint).
* We peek objects from submodule's object store by linking it to the
list of alternate object databases, but the code to do so forgot to
correctly initialize the list.
- (merge 9a6e4f0 jk/initialization-fix-to-add-submodule-odb later to maint).
* The code to prepare the working tree side of temporary directory
for the "dir-diff" feature forgot that symbolic links need not be
special cases and overwrites them. Besides, it was wrong to try
computing the object name of the target of symbolic link, which may
not even exist or may be a directory.
- (merge cfe2d4b da/difftool later to maint).
* A Range: request can be responded with a full response and when
asked properly libcurl knows how to strip the result down to the
requested range. However, we were hand-crafting a range request
and it did not kick in.
+ * Having a leftover .idx file without corresponding .pack file in
+ the repository hurts performance; "git gc" learned to prune them.
+
+ * Apple's common crypto implementation of SHA1_Update() does not take
+ more than 4GB at a time, and we now have a compile-time workaround
+ for it.
+
+ * Produce correct "dirty" marker for shell prompts, even when we
+ are on an orphan or an unborn branch.
+
+ * A build without NO_IPv6 used to use gethostbyname() when guessing
+ user's hostname, instead of getaddrinfo() that is used in other
+ codepaths in such a build.
+ (merge 00bce77 ep/ident-with-getaddrinfo later to maint).
+
+ * The exit code of git-fsck didnot reflect some types of errors found
+ in packed objects, which has been corrected.
+ (merge 8c24d83 dt/fsck-verify-pack-error later to maint).
+
* Code clean-up, minor fixes etc.

- * similarly-named reference. (The fact that reference names with the
- * same leading components can conflict *with each other* is a
- * separate issue that is regulated by verify_refname_available().)
- *
- * Please note that the name field contains the fully-qualified
- * reference (or subdirectory) name. Space could be saved by only
- * storing the relative names. But that would require the full names
- * to be generated on the fly when iterating in do_for_each_ref(), and
