   1Git 2.15 Release Notes
   2======================
   3
   4Backward compatibility notes and other notable changes.
   5
   6 * Use of an empty string as a pathspec element that is used for
   7   'everything matches' is still warned and Git asks users to use a
   8   more explicit '.' for that instead.  The hope is that existing
   9   users will not mind this change, and eventually the warning can be
  10   turned into a hard error, upgrading the deprecation into removal of
  11   this (mis)feature.  That is now scheduled to happen in the upcoming
  12   release.
  13
  14 * Git now avoids blindly falling back to ".git" when the setup
  15   sequence said we are _not_ in Git repository.  A corner case that
  16   happens to work right now may be broken by a call to die("BUG").
  17   We've tried hard to locate such cases and fixed them, but there
  18   might still be cases that need to be addressed--bug reports are
  19   greatly appreciated.

  22Updates since v2.14
  23-------------------
  24
  25UI, Workflows & Features
  26
  27 * An example that is now obsolete has been removed from a sample hook,
  28   and an old example in it that added a sign-off manually has been
  29   improved to use the interpret-trailers command.
  30
  31 * The advice message given when "git rebase" stops for conflicting
  32   changes has been improved.
  33
  34 * The "rerere-train" script (in contrib/) learned the "--overwrite"
  35   option to allow overwriting existing recorded resolutions.
  36   (merge ad53bf79aa rg/rerere-train-overwrite later to maint).
  37
  38 * "git contacts" (in contrib/) now lists the address on the
  39   "Reported-by:" trailer to its output, in addition to those on
  40   S-o-b: and other trailers, to make it easier to notify (and thank)
  41   the original bug reporter.
  42   (merge 09ac673788 eb/contacts-reported-by later to maint).
  43
  44
  45Performance, Internal Implementation, Development Support etc.
  46
  47 * Conversion from uchar[20] to struct object_id continues.
  48
  49 * Start using selected c99 constructs in small, stable and
  50   essentialpart of the system to catch people who care about
  51   older compilers that do not grok them.
  52
  53 * The filter-process interface learned to allow a process with long
  54   latency give a "delayed" response.
  55
  56 * Many uses of comparision callback function the hashmap API uses
  57   cast the callback function type when registering it to
  58   hashmap_init(), which defeats the compile time type checking when
  59   the callback interface changes (e.g. gaining more parameters).
  60   The callback implementations have been updated to take "void *"
  61   pointers and cast them to the type they expect instead.
  62
  63 * Because recent Git for Windows do come with a real msgfmt, the
  64   build procedure for git-gui has been updated to use it instead of a
  65   hand-rolled substitute.
  66   (merge 90dbf226ba js/git-gui-msgfmt-on-windows later to maint).
  67
  68 * "git grep --recurse-submodules" has been reworked to give a more
  69   consistent output across submodule boundary (and do its thing
  70   without having to fork a separate process).
  71
  72 * A helper function to read a single whole line into strbuf
  73   mistakenly triggered OOM error at EOF under certain conditions,
  74   which has been fixed.
  75   (merge 642956cf45 rs/strbuf-getwholeline-fix later to maint).
  76
  77 * The "ref-store" code reorganization continues.
  78
  79
  80Also contains various documentation updates and code clean-ups.
  81
  82
  83Fixes since v2.14
  84-----------------
  85
  86 * "%C(color name)" in the pretty print format always produced ANSI
  87   color escape codes, which was an early design mistake.  They now
  88   honor the configuration (e.g. "color.ui = never") and also tty-ness
  89   of the output medium.
  90   (merge 11b087adfd jk/ref-filter-colors later to maint).
  91
  92 * The http.{sslkey,sslCert} configuration variables are to be
  93   interpreted as a pathname that honors "~[username]/" prefix, but
  94   weren't, which has been fixed.
  95   (merge 8d1549643e jc/http-sslkey-and-ssl-cert-are-paths later to maint).
  96
  97 * Numerous bugs in walking of reflogs via "log -g" and friends have
  98   been fixed.
  99   (merge de239446b6 jk/reflog-walk later to maint).
 100
 101 * "git commit" when seeing an totally empty message said "you did not
 102   edit the message", which is clearly wrong.  The message has been
 103   corrected.
 104   (merge bc17f35f8c ks/commit-abort-on-empty-message-fix later to maint).
 105
 106 * When a directory is not readable, "gitweb" fails to build the
 107   project list.  Work this around by skipping such a directory.
 108   (merge 46a13857fc hb/gitweb-project-list later to maint).
 109
 110 * Some versions of GnuPG fails to kill gpg-agent it auto-spawned
 111   and such a left-over agent can interfere with a test.  Work it
 112   around by attempting to kill one before starting a new test.
 113   (merge 29ff1f8f74 st/lib-gpg-kill-stray-agent later to maint).
 114
 115 * A recently added test for the "credential-cache" helper revealed
 116   that EOF detection done around the time the connection to the cache
 117   daemon is torn down were flaky.  This was fixed by reacting to
 118   ECONNRESET and behaving as if we got an EOF.
 119   (merge 1f180e5eb9 dl/credential-cache-socket-in-xdg-cache later to maint).
 120
 121 * "git log --tag=no-such-tag" showed log starting from HEAD, which
 122   has been fixed---it now shows nothing.
 123   (merge 5d34d1ac06 jk/rev-list-empty-input later to maint).
 124
 125 * The "tag.pager" configuration variable was useless for those who
 126   actually create tag objects, as it interfered with the use of an
 127   editor.  A new mechanism has been introduced for commands to enable
 128   pager depending on what operation is being carried out to fix this,
 129   and then "git tag -l" is made to run pager by default.
 130   (merge 595d59e2b5 ma/pager-per-subcommand-action later to maint).
 131
 132 * "git push --recurse-submodules $there HEAD:$target" was not
 133   propagated down to the submodules, but now it is.
 134   (merge c7be7201a7 bw/push-options-recursively-to-submodules later to maint).
 135
 136 * Commands like "git rebase" accepted the --rerere-autoupdate option
 137   from the command line, but did not always use it.  This has been
 138   fixed.
 139   (merge f826fb799e pw/sequence-rerere-autoupdate later to maint).
 140
 141 * "git clone --recurse-submodules --quiet" did not pass the quiet
 142   option down to submodules.
 143   (merge 03c004c581 bw/clone-recursive-quiet later to maint).
 144
 145 * Test portability fix for OBSD.
 146   (merge bed67874e2 rs/obsd-getcwd-workaround later to maint).
 147   (merge 4c7fda8fc1 rs/t4062-obsd later to maint).
 148
 149 * Portability fix for OBSD.
 150   (merge 29c2eda80b rs/in-obsd-basename-dirname-take-const later to maint).
 151
 152 * "git am -s" has been taught that some input may end with a trailer
 153   block that is not Signed-off-by: and it should refrain from adding
 154   an extra blank line before adding a new sign-off in such a case.
 155   (merge 735285b403 pw/am-signoff later to maint).
 156
 157 * "git svn" used with "--localtime" option did not compute the tz
 158   offset for the timestamp in question and instead always used the
 159   current time, which has been corrected.
 160   (merge 1adc4b9a58 ur/svn-local-zone later to maint).
 161
 162 * Memory leak in an error codepath has been plugged.
 163   (merge 83cd6f9017 rs/fsck-obj-leakfix later to maint).
 164   (merge 896dca3ab7 rs/unpack-entry-leakfix later to maint).
 165   (merge 149d8cbb2e rs/win32-syslog-leakfix later to maint).
 166
