As a preparatory step + to make "git format-patch" available to the internal callers, these + codepaths have been updated to consistently write into that FILE* + instead. + + * Conversion from unsigned char sha1[20] to struct object_id + continues. + + * Improve the look of the way "git fetch" reports what happened to + each ref that was fetched. + + * The .c/.h sources are marked as such in our .gitattributes file so + that "git diff -W" and friends would work better. + + * Code clean-up to avoid using a variable string that compilers may + feel untrustable as printf-style format given to write_file() + helper function. + + * "git p4" used a location outside $GIT_DIR/refs/ to place its + temporary branches, which has been moved to refs/git-p4-tmp/. + + * Existing autoconf generated test for the need to link with pthread + library did not check all the functions from pthread libraries; + recent FreeBSD has some functions in libc but not others, and we + mistakenly thought linking with libc is enough when it is not. + + * When "git fsck" reports a broken link (e.g. a tree object contains + a blob that does not exist), both containing object and the object + that is referred to were reported with their 40-hex object names. + The command learned the "--name-objects" option to show the path to + the containing object from existing refs (e.g. "HEAD~24^2:file.txt"). + + * Allow http daemon tests in Travis CI tests. + + * Makefile assumed that -lrt is always available on platforms that + want to use clock_gettime() and CLOCK_MONOTONIC, which is not a + case for recent Mac OS X. The necessary symbols are often found in + libc on many modern systems and having -lrt on the command line, as + long as the library exists, had no effect, but when the platform + removes librt.a that is a different matter--having -lrt will break + the linkage. + + This change could be seen as a regression for those who do need to + specify -lrt, as they now specifically ask for NEEDS_LIBRT when + building. Hopefully they are in the minority these days. + + * Further preparatory work on the refs API before the pluggable + backend series can land. + + * Error handling in the codepaths that updates refs has been + improved. + + * The API to iterate over all the refs (i.e. for_each_ref(), etc.) + has been revamped. + + * The handling of the "text=auto" attribute has been corrected. + $ echo "* text=auto eol=crlf" >.gitattributes + used to have the same effect as + $ echo "* text eol=crlf" >.gitattributes + i.e. declaring all files are text (ignoring "auto"). The + combination has been fixed to be equivalent to doing + $ git config core.autocrlf true + + * Documentation has been updated to show better example usage + of the updated "text=auto" attribute. + + * A few tests that specifically target "git rebase -i" have been + added. + + * Dumb http transport on the client side has been optimized. + (merge ecba195 ew/http-walker later to maint). + + * Users of the parse_options_concat() API function need to allocate + extra slots in advance and fill them with OPT_END() when they want + to decide the set of supported options dynamically, which makes the + code error-prone and hard to read. This has been corrected by tweaking + the API to allocate and return a new copy of "struct option" array. + + * "git fetch" exchanges batched have/ack messages between the sender + and the receiver, initially doubling every time and then falling + back to enlarge the window size linearly. The "smart http" + transport, being an half-duplex protocol, outgrows the preset limit + too quickly and becomes inefficient when interacting with a large + repository. The internal mechanism learned to grow the window size + more aggressively when working with the "smart http" transport. + + * Tests for "git svn" have been taught to reuse the lib-httpd test + infrastructure when testing the subversion integration that + interacts with subversion repositories served over the http:// + protocol. + (merge a8a5d25 ew/git-svn-http-tests later to maint). + + * "git pack-objects" has a few options that tell it not to pack + objects found in certain packfiles, which require it to scan .idx + files of all available packs. The codepaths involved in these + operations have been optimized for a common case of not having any + non-local pack and/or any .kept pack. + + * The t3700 test about "add --chmod=-x" have been made a bit more + robust and generally cleaned up. + (merge 766cdc4 ib/t3700-add-chmod-x-updates later to maint). + + * The build procedure learned PAGER_ENV knob that lists what default + environment variable settings to export for popular pagers. This + mechanism is used to tweak the default settings to MORE on FreeBSD. + (merge 995bc22 ew/build-time-pager-tweaks later to maint). + + * The http-backend (the server-side component of smart-http + transport) used to trickle the HTTP header one at a time. Now + these write(2)s are batched. + (merge b36045c ew/http-backend-batch-headers later to maint). + + * When "git rebase" tries to compare set of changes on the updated + upstream and our own branch, it computes patch-id for all of these + changes and attempts to find matches. This has been optimized by + lazily computing the full patch-id (which is expensive) to be + compared only for changes that touch the same set of paths. + (merge ba67504 kw/patch-ids-optim later to maint). + + * A handful of tests that were broken under gettext-poison build have + been fixed. + + * The recent i18n patch we added during this cycle did a bit too much + refactoring of the messages to avoid word-legos; the repetition has + been reduced to help translators. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v2.9 +---------------- + +Unless otherwise noted, all the fixes since v2.8 in the maintenance +track are contained in this release (see the maintenance releases' +notes for details). + + * The commands in `git log` family take %C(auto) in a custom format + string. This unconditionally turned the color on, ignoring + --no-color or with --color=auto when the output is not connected to + a tty; this was corrected to make the format truly behave as + "auto". + + * "git rev-list --count" whose walk-length is limited with "-n" + option did not work well with the counting optimized to look at the + bitmap index. + + * "git show -W" (extend hunks to cover the entire function, delimited + by lines that match the "funcname" pattern) used to show the entire + file when a change added an entire function at the end of the file, + which has been fixed. + + * The documentation set has been updated so that literal commands, + configuration variables and environment variables are consistently + typeset in fixed-width font and bold in manpages. + + * "git svn propset" subcommand that was added in 2.3 days is + documented now. + + * The documentation tries to consistently spell "GPG"; when + referring to the specific program name, "gpg" is used. + + * "git reflog" stopped upon seeing an entry that denotes a branch + creation event (aka "unborn"), which made it appear as if the + reflog was truncated. + + * The git-prompt scriptlet (in contrib/) was not friendly with those + who uses "set -u", which has been fixed. + + * compat/regex code did not cleanly compile. + + * A codepath that used alloca(3) to place an unbounded amount of data + on the stack has been updated to avoid doing so. + + * "git update-index --add --chmod=+x file" may be usable as an escape + hatch, but not a friendly thing to force for people who do need to + use it regularly. "git add --chmod=+x file" can be used instead. + + * Build improvements for gnome-keyring (in contrib/) + + * "git status" used to say "working directory" when it meant "working + tree". + + * Comments about misbehaving FreeBSD shells have been clarified with + the version number (9.x and before are broken, newer ones are OK). + + * "git cherry-pick A" worked on an unborn branch, but "git + cherry-pick A..B" didn't. + + * Fix an unintended regression in v2.9 that breaks "clone --depth" + that recurses down to submodules by forcing the submodules to also + be cloned shallowly, which many server instances that host upstream + of the submodules are not prepared for. + + * Fix unnecessarily waste in the idiomatic use of ': ${VAR=default}' + to set the default value, without enclosing it in double quotes. + + * Some platform-specific code had non-ANSI strict declarations of C + functions that do not take any parameters, which has been + corrected. + + * The internal code used to show local timezone offset is not + prepared to handle timestamps beyond year 2100, and gave a + bogus offset value to the caller. Use a more benign looking + +0000 instead and let "git log" going in such a case, instead + of aborting. + + * One among four invocations of readlink(1) in our test suite has + been rewritten so that the test can run on systems without the + command (others are in valgrind test framework and t9802). + + * t/perf needs /usr/bin/time with GNU extension; the invocation of it + is updated to "gtime" on Darwin. + + * A bug, which caused "git p4" while running under verbose mode to + report paths that are omitted due to branch prefix incorrectly, has + been fixed; the command said "Ignoring file outside of prefix" for + paths that are _inside_. + + * The top level documentation "git help git" still pointed at the + documentation set hosted at now-defunct google-code repository. + Update it to point to https://git.github.io/htmldocs/git.html + instead. + + * A helper function that takes the contents of a commit object and + finds its subject line did not ignore leading blank lines, as is + commonly done by other codepaths. Make it ignore leading blank + lines to match. + + * For a long time, we carried an in-code comment that said our + colored output would work only when we use fprintf/fputs on + Windows, which no longer is the case for the past few years. + + * "gc.autoPackLimit" when set to 1 should not trigger a repacking + when there is only one pack, but the code counted poorly and did + so. + + * Add a test to specify the desired behaviour that currently is not + available in "git rebase -Xsubtree=...". + + * More mark-up updates to typeset strings that are expected to + literally typed by the end user in fixed-width font. + + * "git commit --amend --allow-empty-message -S" for a commit without + any message body could have misidentified where the header of the + commit object ends. + + * "git rebase -i --autostash" did not restore the auto-stashed change + when the operation was aborted. + + * Git does not know what the contents in the index should be for a + path added with "git add -N" yet, so "git grep --cached" should not + show hits (or show lack of hits, with -L) in such a path, but that + logic does not apply to "git grep", i.e. searching in the working + tree files. But we did so by mistake, which has been corrected. + + * "git blame -M" missed a single line that was moved within the file. + + * Fix recently introduced codepaths that are involved in parallel + submodule operations, which gave up on reading too early, and + could have wasted CPU while attempting to write under a corner + case condition. + + * "git grep -i" has been taught to fold case in non-ascii locales + correctly. + + * A test that unconditionally used "mktemp" learned that the command + is not necessarily available everywhere. + + * There are certain house-keeping tasks that need to be performed at + the very beginning of any Git program, and programs that are not + built-in commands had to do them exactly the same way as "git" + potty does. It was easy to make mistakes in one-off standalone + programs (like test helpers). A common "main()" function that + calls cmd_main() of individual program has been introduced to + make it harder to make mistakes. + (merge de61ceb jk/common-main later to maint). + + * The test framework learned a new helper test_match_signal to + check an exit code from getting killed by an expected signal. + + * General code clean-up around a helper function to write a + single-liner to a file. + (merge 7eb6e10 jk/write-file later to maint). + + * One part of "git am" had an oddball helper function that called + stuff from outside "his" as opposed to calling what we have "ours", + which was not gender-neutral and also inconsistent with the rest of + the system where outside stuff is usuall called "theirs" in + contrast to "ours". + + * "git blame file" allowed the lineage of lines in the uncommitted, + unadded contents of "file" to be inspected, but it refused when + "file" did not appear in the current commit. When "file" was + created by renaming an existing file (but the change has not been + committed), this restriction was unnecessarily tight. + + * "git add -N dir/file && git write-tree" produced an incorrect tree + when there are other paths in the same directory that sorts after + "file". + + * "git fetch http://user:pass@host/repo..." scrubbed the userinfo + part, but "git push" didn't. + + * "git merge" with renormalization did not work well with + merge-recursive, due to "safer crlf" conversion kicking in when it + shouldn't. + (merge 1335d76 jc/renormalize-merge-kill-safer-crlf later to maint). + + * The use of strbuf in "git rm" to build filename to remove was a bit + suboptimal, which has been fixed. + + * An age old bug that caused "git diff --ignore-space-at-eol" + misbehave has been fixed. + + * "git notes merge" had a code to see if a path exists (and fails if + it does) and then open the path for writing (when it doesn't). + Replace it with open with O_EXCL. + + * "git pack-objects" and "git index-pack" mostly operate with off_t + when talking about the offset of objects in a packfile, but there + were a handful of places that used "unsigned long" to hold that + value, leading to an unintended truncation. + + * Recent update to "git daemon" tries to enable the socket-level + KEEPALIVE, but when it is spawned via inetd, the standard input + file descriptor may not necessarily be connected to a socket. + Suppress an ENOTSOCK error from setsockopt(). + + * Recent FreeBSD stopped making perl available at /usr/bin/perl; + switch the default the built-in path to /usr/local/bin/perl on not + too ancient FreeBSD releases. + + * "git commit --help" said "--no-verify" is only about skipping the + pre-commit hook, and failed to say that it also skipped the + commit-msg hook. + + * "git merge" in Git v2.9 was taught to forbid merging an unrelated + lines of history by default, but that is exactly the kind of thing + the "--rejoin" mode of "git subtree" (in contrib/) wants to do. + "git subtree" has been taught to use the "--allow-unrelated-histories" + option to override the default. + + * The build procedure for "git persistent-https" helper (in contrib/) + has been updated so that it can be built with more recent versions + of Go. + + * There is an optimization used in "git diff $treeA $treeB" to borrow + an already checked-out copy in the working tree when it is known to + be the same as the blob being compared, expecting that open/mmap of + such a file is faster than reading it from the object store, which + involves inflating and applying delta. This however kicked in even + when the checked-out copy needs to go through the convert-to-git + conversion (including the clean filter), which defeats the whole + point of the optimization. The optimization has been disabled when + the conversion is necessary. + + * "git -c grep.patternType=extended log --basic-regexp" misbehaved + because the internal API to access the grep machinery was not + designed well. + + * Windows port was failing some tests in t4130, due to the lack of + inum in the returned values by its lstat(2) emulation. + + * The reflog output format is documented better, and a new format + --date=unix to report the seconds-since-epoch (without timezone) + has been added. + (merge 442f6fd jk/reflog-date later to maint). + + * "git difftool <paths>..." started in a subdirectory failed to + interpret the paths relative to that directory, which has been + fixed. + + * The characters in the label shown for tags/refs for commits in + "gitweb" output are now properly escaped for proper HTML output. + + * FreeBSD can lie when asked mtime of a directory, which made the + untracked cache code to fall back to a slow-path, which in turn + caused tests in t7063 to fail because it wanted to verify the + behaviour of the fast-path. + + * Squelch compiler warnings for nedmalloc (in compat/) library. + + * A small memory leak in the command line parsing of "git blame" + has been plugged. + + * The API documentation for hashmap was unclear if hashmap_entry + can be safely discarded without any other consideration. State + that it is safe to do so. + + * Not-so-recent rewrite of "git am" that started making internal + calls into the commit machinery had an unintended regression, in + that no matter how many seconds it took to apply many patches, the + resulting committer timestamp for the resulting commits were all + the same. + + * "git push --force-with-lease" already had enough logic to allow + ensuring that such a push results in creation of a ref (i.e. the + receiving end did not have another push from sideways that would be + discarded by our force-pushing), but didn't expose this possibility + to the users. It does so now. + (merge 9eed4f3 jk/push-force-with-lease-creation later to maint). + + * The mechanism to limit the pack window memory size, when packing is + done using multiple threads (which is the default), is per-thread, + but this was not documented clearly. + (merge 954176c ms/document-pack-window-memory-is-per-thread later to maint). + + * "import-tars" fast-import script (in contrib/) used to ignore a + hardlink target and replaced it with an empty file, which has been + corrected to record the same blob as the other file the hardlink is + shared with. + (merge 04e0869 js/import-tars-hardlinks later to maint). + + * "git mv dir non-existing-dir/" did not work in some environments + the same way as existing mainstream platforms.

Save it to a file in $GIT_DIR and show it next time the "gc + --auto" is run. + + * The submodule code has been taught to work better with separate + work trees created via "git worktree add". + + * "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. + + * A recent "filter-branch --msg-filter" broke skipping of the commit + object header, which is fixed. + + * 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. + + * A test for interaction between untracked cache and sparse checkout + added in Git 2.5 days were flaky. + + * 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. + + * 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. + + * "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). + + * The linkage order of libraries was wrong in places around libcurl. + + * The name-hash subsystem that is used to cope with case insensitive + filesystems keeps track of directories and their on-filesystem + cases for all the paths in the index by holding a pointer to a + randomly chosen cache entry that is inside the directory (for its + ce->ce_name component). This pointer was not updated even when the + 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. + + * "git merge-file" tried to signal how many conflicts it found, which + obviously would not work well when there are too many of them. + + * The error message from "git blame --contents --reverse" incorrectly + talked about "--contents --children". + + * "git imap-send" did not compile well with older version of cURL library. + + * 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. + + * "git --literal-pathspecs add -u/-A" without any command line + argument misbehaved ever since Git 2.0. + + * "git daemon" uses "run_command()" without "finish_command()", so it + needs to release resources itself, which it forgot to do. + + * "git status --branch --short" accessed beyond the constant string + "HEAD", which has been corrected. + + * 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. + + * 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. + + * 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.
