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. + (merge e82675a rs/help-c-source-with-gitattributes later to maint). + + * 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. + (merge a9b02de ew/autoconf-pthread later to maint). + + * 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. + (merge d9d1426 ls/travis-enable-httpd-tests later to maint). + + * 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. + + * 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. + (merge 023ff39 jk/parse-options-concat later to maint). + + * "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). + + +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. + (merge deb8e15 rs/rm-strbuf-optim later to maint). + + * 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. + (merge def480f os/no-verify-skips-commit-msg-too later to maint). + + * "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. + (merge 0f12c7d da/subtree-2.9-regression later to maint). + + * 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. + (merge accb613 pm/build-persistent-https-with-recent-go later to maint). + + * 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.
