Git 2.15 Release Notes ====================== Backward compatibility notes and other notable changes. * Use of an empty string as a pathspec element that is used for 'everything matches' is still warned and Git asks users to use a more explicit '.' for that instead. 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. 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. (merge ad53bf79aa rg/rerere-train-overwrite later to maint). * "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. (merge 09ac673788 eb/contacts-reported-by later to maint). 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. (merge 90dbf226ba js/git-gui-msgfmt-on-windows later to maint). * "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. 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 = never") and also tty-ness of the output medium. (merge 11b087adfd jk/ref-filter-colors later to maint). * The http.{sslkey,sslCert} configuration variables are to be interpreted as a pathname that honors "~[username]/" prefix, but weren't, which has been fixed. (merge 8d1549643e jc/http-sslkey-and-ssl-cert-are-paths later to maint). * Numerous bugs in walking of reflogs via "log -g" and friends have been fixed. (merge de239446b6 jk/reflog-walk later to maint). * "git commit" when seeing an totally empty message said "you did not edit the message", which is clearly wrong. The message has been corrected. (merge bc17f35f8c ks/commit-abort-on-empty-message-fix later to maint). * When a directory is not readable, "gitweb" fails to build the project list. Work this around by skipping such a directory. (merge 46a13857fc hb/gitweb-project-list later to maint). * 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. (merge 29ff1f8f74 st/lib-gpg-kill-stray-agent later to maint). * 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. (merge 1f180e5eb9 dl/credential-cache-socket-in-xdg-cache later to maint). * "git log --tag=no-such-tag" showed log starting from HEAD, which has been fixed---it now shows nothing. (merge 5d34d1ac06 jk/rev-list-empty-input later to maint). * 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. (merge 595d59e2b5 ma/pager-per-subcommand-action later to maint). * "git push --recurse-submodules $there HEAD:$target" was not propagated down to the submodules, but now it is. (merge c7be7201a7 bw/push-options-recursively-to-submodules later to maint). * Commands like "git rebase" accepted the --rerere-autoupdate option from the command line, but did not always use it. This has been fixed. (merge f826fb799e pw/sequence-rerere-autoupdate later to maint). * "git clone --recurse-submodules --quiet" did not pass the quiet option down to submodules. (merge 03c004c581 bw/clone-recursive-quiet later to maint). * Test portability fix for OBSD. (merge bed67874e2 rs/obsd-getcwd-workaround later to maint). (merge 4c7fda8fc1 rs/t4062-obsd later to maint). * Portability fix for OBSD. (merge 29c2eda80b rs/in-obsd-basename-dirname-take-const later to maint). * "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. (merge 735285b403 pw/am-signoff later to maint). * "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. (merge 1adc4b9a58 ur/svn-local-zone later to maint). * Memory leak in an error codepath has been plugged. (merge 83cd6f9017 rs/fsck-obj-leakfix later to maint). (merge 896dca3ab7 rs/unpack-entry-leakfix later to maint). (merge 149d8cbb2e rs/win32-syslog-leakfix later to maint). * Other minor doc, test and build updates and code cleanups. (merge 5b114f3bb0 rs/bswap-ubsan-fix later to maint). (merge 168e63554c rs/move-array later to maint). (merge 268ba20110 rs/stat-data-unaligned-reads-fix later to maint).
