The hope is that existing users will not mind this change, and eventually the warning can be turned into a hard error, upgrading the deprecation into removal of this (mis)feature. That is now scheduled to happen in the upcoming release. * Git now avoids blindly falling back to ".git" when the setup sequence said we are _not_ in Git repository. A corner case that happens to work right now may be broken by a call to die("BUG"). We've tried hard to locate such cases and fixed them, but there might still be cases that need to be addressed--bug reports are greatly appreciated. * "branch --set-upstream" that has been deprecated in Git 1.8 has finally been retired. Updates since v2.14 ------------------- UI, Workflows & Features * An example that is now obsolete has been removed from a sample hook, and an old example in it that added a sign-off manually has been improved to use the interpret-trailers command. * The advice message given when "git rebase" stops for conflicting changes has been improved. * The "rerere-train" script (in contrib/) learned the "--overwrite" option to allow overwriting existing recorded resolutions. * "git contacts" (in contrib/) now lists the address on the "Reported-by:" trailer to its output, in addition to those on S-o-b: and other trailers, to make it easier to notify (and thank) the original bug reporter. * "git rebase", especially when it is run by mistake and ends up trying to replay many changes, spent long time in silence. The command has been taught to show progress report when it spends long time preparing these many changes to replay (which would give the user a chance to abort with ^C). * "git merge" learned a "--signoff" option to add the Signed-off-by: trailer with the committer's name. * "git diff" learned to optionally paint new lines that are the same as deleted lines elsewhere differently from genuinely new lines. * "git interpret-trailers" learned to take the trailer specifications from the command line that overrides the configured values. * "git interpret-trailers" has been taught a "--parse" and a few other options to make it easier for scripts to grab existing trailer lines from a commit log message. * "gitweb" shows a link to visit the 'raw' contents of blbos in the history overview page. * "[gc] rerereResolved =3D 5.days" used to be invalid, as the variable is defined to take an integer counting the number of days. It now is allowed. * The code to acquire a lock on a reference (e.g. while accepting a push from a client) used to immediately fail when the reference is already locked---now it waits for a very short while and retries, which can make it succeed if the lock holder was holding it during a read-only operation. * "branch --set-upstream" that has been deprecated in Git 1.8 has finally been retired. * The codepath to call external process filter for smudge/clean operation learned to show the progress meter. * "git rev-parse" learned "--is-shallow-repository", that is to be used in a way similar to existing "--is-bare-repository" and friends. * "git describe --match " has been taught to play well with the "--all" option. * "git branch" learned "-c/-C" to create a new branch by copying an existing one. * Some commands (most notably "git status") makes an opportunistic update when performing a read-only operation to help optimize later operations in the same repository. The new "--no-optional-locks" option can be passed to Git to disable them. Performance, Internal Implementation, Development Support etc. * Conversion from uchar[20] to struct object_id continues. * Start using selected c99 constructs in small, stable and essentialpart of the system to catch people who care about older compilers that do not grok them. * The filter-process interface learned to allow a process with long latency give a "delayed" response. * Many uses of comparision callback function the hashmap API uses cast the callback function type when registering it to hashmap_init(), which defeats the compile time type checking when the callback interface changes (e.g. gaining more parameters). The callback implementations have been updated to take "void *" pointers and cast them to the type they expect instead. * Because recent Git for Windows do come with a real msgfmt, the build procedure for git-gui has been updated to use it instead of a hand-rolled substitute. * "git grep --recurse-submodules" has been reworked to give a more consistent output across submodule boundary (and do its thing without having to fork a separate process). * A helper function to read a single whole line into strbuf mistakenly triggered OOM error at EOF under certain conditions, which has been fixed. (merge 642956cf45 rs/strbuf-getwholeline-fix later to maint). * The "ref-store" code reorganization continues. * "git commit" used to discard the index and re-read from the filesystem just in case the pre-commit hook has updated it in the middle; this has been optimized out when we know we do not run the pre-commit hook. (merge 680ee550d7 kw/commit-keep-index-when-pre-commit-is-not-run late= r to maint). * Updates to the HTTP layer we made recently unconditionally used features of libCurl without checking the existence of them, causing compilation errors, which has been fixed. Also migrate the code to check feature macros, not version numbers, to cope better with libCurl that vendor ships with backported features. * The API to start showing progress meter after a short delay has been simplified. (merge 8aade107dd jc/simplify-progress later to maint). * Code clean-up to avoid mixing values read from the .gitmodules file and values read from the .git/config file. * We used to spend more than necessary cycles allocating and freeing piece of memory while writing each index entry out. This has been optimized. * Platforms that ship with a separate sha1 with collision detection library can link to it instead of using the copy we ship as part of our source tree. * Code around "notes" have been cleaned up. (merge 3964281524 mh/notes-cleanup later to maint). * The long-standing rule that an in-core lockfile instance, once it is used, must not be freed, has been lifted and the lockfile and tempfile APIs have been updated to reduce the chance of programming errors. * Our hashmap implementation in hashmap.[ch] is not thread-safe when adding a new item needs to expand the hashtable by rehashing; add an API to disable the automatic rehashing to work it around. * Many of our programs consider that it is OK to release dynamic storage that is used throughout the life of the program by simply exiting, but this makes it harder to leak detection tools to avoid reporting false positives. Plug many existing leaks and introduce a mechanism for developers to mark that the region of memory pointed by a pointer is not lost/leaking to help these tools. * As "git commit" to conclude a conflicted "git merge" honors the commit-msg hook, "git merge" that records a merge commit that cleanly auto-merges should, but it didn't. * The codepath for "git merge-recursive" has been cleaned up. * Many leaks of strbuf have been fixed. * "git imap-send" has our own implementation of the protocol and also can use more recent libCurl with the imap protocol support. Update the latter so that it can use the credential subsystem, and then make it the default option to use, so that we can eventually deprecate and remove the former. * "make style" runs git-clang-format to help developers by pointing out coding style issues. * A test to demonstrate "git mv" failing to adjust nested submodules has been added. (merge c514167df2 hv/mv-nested-submodules-test later to maint). * On Cygwin, "ulimit -s" does not report failure but it does not work at all, which causes an unexpected success of some tests that expect failures under a limited stack situation. This has been fixed. * Many codepaths have been updated to squelch -Wimplicit-fallthrough warnings from Gcc 7 (which is a good code hygiene). * Add a helper for DLL loading in anticipation for its need in a future topic RSN. * "git status --ignored", when noticing that a directory without any tracked path is ignored, still enumerated all the ignored paths in the directory, which is unnecessary. The codepath has been optimized to avoid this overhead. * The final batch to "git rebase -i" updates to move more code from the shell script to C has been merged. * Operations that do not touch (majority of) packed refs have been optimized by making accesses to packed-refs file lazy; we no longer pre-parse everything, and an access to a single ref in the packed-refs does not touch majority of irrelevant refs, either. * Add comment to clarify that the style file is meant to be used with clang-5 and the rules are still work in progress. Also contains various documentation updates and code clean-ups. Fixes since v2.14 ----------------- * "%C(color name)" in the pretty print format always produced ANSI color escape codes, which was an early design mistake. They now honor the configuration (e.g. "color.ui =3D never") and also tty-ness of the output medium. * The http.{sslkey,sslCert} configuration variables are to be interpreted as a pathname that honors "~[username]/" prefix, but weren't, which has been fixed. * Numerous bugs in walking of reflogs via "log -g" and friends have been fixed. * "git commit" when seeing an totally empty message said "you did not edit the message", which is clearly wrong. The message has been corrected. * When a directory is not readable, "gitweb" fails to build the project list. Work this around by skipping such a directory. * Some versions of GnuPG fails to kill gpg-agent it auto-spawned and such a left-over agent can interfere with a test. Work it around by attempting to kill one before starting a new test. * A recently added test for the "credential-cache" helper revealed that EOF detection done around the time the connection to the cache daemon is torn down were flaky. This was fixed by reacting to ECONNRESET and behaving as if we got an EOF. * "git log --tag=3Dno-such-tag" showed log starting from HEAD, which has been fixed---it now shows nothing. * The "tag.pager" configuration variable was useless for those who actually create tag objects, as it interfered with the use of an editor. A new mechanism has been introduced for commands to enable pager depending on what operation is being carried out to fix this, and then "git tag -l" is made to run pager by default. * "git push --recurse-submodules $there HEAD:$target" was not propagated down to the submodules, but now it is. * Commands like "git rebase" accepted the --rerere-autoupdate option from the command line, but did not always use it. This has been fixed. * "git clone --recurse-submodules --quiet" did not pass the quiet option down to submodules. * Test portability fix for OBSD. * Portability fix for OBSD. * "git am -s" has been taught that some input may end with a trailer block that is not Signed-off-by: and it should refrain from adding an extra blank line before adding a new sign-off in such a case. * "git svn" used with "--localtime" option did not compute the tz offset for the timestamp in question and instead always used the current time, which has been corrected. * Memory leak in an error codepath has been plugged. * "git stash -u" used the contents of the committed version of the ".gitignore" file to decide which paths are ignored, even when the file has local changes. The command has been taught to instead use the locally modified contents. * bash 4.4 or newer gave a warning on NUL byte in command substitution done in "git stash"; this has been squelched. * "git grep -L" and "git grep --quiet -L" reported different exit codes; this has been corrected. * When handshake with a subprocess filter notices that the process asked for an unknown capability, Git did not report what program the offending subprocess was running. This has been corrected. * "git apply" that is used as a better "patch -p1" failed to apply a taken from a file with CRLF line endings to a file with CRLF line endings. The root cause was because it misused convert_to_git() that tried to do "safe-crlf" processing by looking at the index entry at the same path, which is a nonsense---in that mode, "apply" is not working on the data in (or derived from) the index at all. This has been fixed. * Killing "git merge --edit" before the editor returns control left the repository in a state with MERGE_MSG but without MERGE_HEAD, which incorrectly tells the subsequent "git commit" that there was a squash merge in progress. This has been fixed. * "git archive" did not work well with pathspecs and the export-ignore attribute. * In addition to "cc: # cruft", "cc: a@dd.re.ss # cruft" was taught to "git send-email" as a valid way to tell it that it needs to also send a carbon copy to in the trailer section. (merge cc90750677 mm/send-email-cc-cruft later to maint). * "git branch -M a b" while on a branch that is completely unrelated to either branch a or branch b misbehaved when multiple worktree was in use. This has been fixed. (merge 31824d180d nd/worktree-kill-parse-ref later to maint). * "git gc" and friends when multiple worktrees are used off of a single repository did not consider the index and per-worktree refs of other worktrees as the root for reachability traversal, making objects that are in use only in other worktrees to be subject to garbage collection. * A regression to "gitk --bisect" by a recent update has been fixed. (merge 1d0538e486 mh/packed-ref-store-prep later to maint). * "git -c submodule.recurse=3Dyes pull" did not work as if the "--recurse-submodules" option was given from the command line. This has been corrected. * Unlike "git commit-tree < file", "git commit-tree -F file" did not pass the contents of the file verbatim and instead completed an incomplete line at the end, if exists. The latter has been updated to match the behaviour of the former. (merge c818e74332 rk/commit-tree-make-F-verbatim later to maint). * Many codepaths did not diagnose write failures correctly when disks go full, due to their misuse of write_in_full() helper function, which have been corrected. (merge f48ecd38cb jk/write-in-full-fix later to maint). * "git help co" now says "co is aliased to ...", not "git co is". (merge b3a8076e0d ks/help-alias-label later to maint). * "git archive", especially when used with pathspec, stored an empty directory in its output, even though Git itself never does so. This has been fixed. (merge 4318094047 rs/archive-excluded-directory later to maint). * API error-proofing which happens to also squelch warnings from GCC. (merge c788c54cde tg/refs-allowed-flags later to maint). * The explanation of the cut-line in the commit log editor has been slightly tweaked. (merge 8c4b1a3593 ks/commit-do-not-touch-cut-line later to maint). * "git gc" tries to avoid running two instances at the same time by reading and writing pid/host from and to a lock file; it used to use an incorrect fscanf() format when reading, which has been corrected. (merge afe2fab72c aw/gc-lockfile-fscanf-fix later to maint). * The scripts to drive TravisCI has been reorganized and then an optimization to avoid spending cycles on a branch whose tip is tagged has been implemented. (merge 8376eb4a8f ls/travis-scriptify later to maint). * The test linter has been taught that we do not like "echo -e". (merge 1a6d46895d tb/test-lint-echo-e later to maint). * Code cmp.std.c nitpick. (merge ac7da78ede mh/for-each-string-list-item-empty-fix later to main= t). * A regression fix for 2.11 that made the code to read the list of alternate object stores overrun the end of the string. (merge f0f7bebef7 jk/info-alternates-fix later to maint). * "git describe --match" learned to take multiple patterns in v2.13 series, but the feature ignored the patterns after the first one and did not work at all. This has been fixed. (merge da769d2986 jk/describe-omit-some-refs later to maint). * "git filter-branch" cannot reproduce a history with a tag without the tagger field, which only ancient versions of Git allowed to be created. This has been corrected. (merge b2c1ca6b4b ic/fix-filter-branch-to-handle-tag-without-tagger la= ter to maint). * "git cat-file --textconv" started segfaulting recently, which has been corrected. (merge cc0ea7c9e5 jk/diff-blob later to maint). * The built-in pattern to detect the "function header" for HTML did not match

..

elements without any attributes, which has been fixed. (merge 9c03caca2c ik/userdiff-html-h-element-fix later to maint). * "git mailinfo" was loose in decoding quoted printable and produced garbage when the two letters after the equal sign are not hexadecimal. This has been fixed. (merge c8cf423eab rs/mailinfo-qp-decode-fix later to maint). * The machinery to create xdelta used in pack files received the sizes of the data in size_t, but lost the higher bits of them by storing them in "unsigned int" during the computation, which is fixed. * The delta format used in the packfile cannot reference data at offset larger than what can be expressed in 4-byte, but the generator for the data failed to make sure the offset does not overflow. This has been corrected. * The documentation for '-X
