Make it ignore leading blank + lines to match. + + * 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 rebase -i --autostash" did not restore the auto-stashed change + when the operation was aborted. + + * "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. + + * More mark-up updates to typeset strings that are expected to + literally typed by the end user in fixed-width font. + + * 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. + + * 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 usually called "theirs" in + contrast to "ours". + + * The test framework learned a new helper test_match_signal to + check an exit code from getting killed by an expected signal. + + * "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. + + * "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. + + * 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 status" learned to suggest "merge --abort" during a conflicted + merge, just like it already suggests "rebase --abort" during a + conflicted rebase. + + * The .c/.h sources are marked as such in our .gitattributes file so + that "git diff -W" and friends would work better. + + * 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. + + * Allow http daemon tests in Travis CI tests. + + * 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. + + * The use of strbuf in "git rm" to build filename to remove was a bit + suboptimal, which has been fixed. + + * "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 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 netmalloc (in compat/) library. + + * 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 difftool <paths>..." started in a subdirectory failed to + interpret the paths relative to that directory, which has been + fixed. + +Also contains minor documentation updates and code clean-ups. |
