Git v1.7.6 Release Notes
========================
Updates since v1.7.5
--------------------
* Various git-svn updates.
* Updates the way content tags are handled in gitweb. Also adds
a UI to choose common timezone for displaying the dates.
* Similar to branch names, tagnames that begin with "-" are now
disallowed.
* Clean-up of the C part of i18n (but not l10n---please wait)
continues.
* The scripting part of the codebase is getting prepared for i18n/l10n.
* Pushing and pulling from a repository with large number of refs that
point to identical commits are optimized by not listing the same commit
during the common ancestor negotiation exchange with the other side.
* Adding a file larger than core.bigfilethreshold (defaults to 1/2 Gig)
using "git add" will send the contents straight to a packfile without
having to hold it and its compressed representation both at the same
time in memory.
* Processes spawned by "[alias] <name> = !process" in the configuration
can inspect GIT_PREFIX environment variable to learn where in the
working tree the original command was invoked.
* A magic pathspec ":/" tells a command that limits its operation to
the current directory when ran from a subdirectory to work on the
entire working tree. In general, ":/path/to/file" would be relative
to the root of the working tree hierarchy.
After "git reset --hard; edit Makefile; cd t/", "git add -u" would
be a no-op, but "git add -u :/" would add the updated contents of
the Makefile at the top level. If you want to name a path in the
current subdirectory whose unusual name begins with ":/", you can
name it by "./:/that/path" or by "\:/that/path".
* "git blame" learned "--abbrev[=<n>]" option to control the minimum
number of hexdigits shown for commit object names.
* "git blame" learned "--line-porcelain" that is less efficient but is
easier to parse.
* Aborting "git commit --interactive" discards updates to the index
made during the interactive session.
* "git commit" learned a "--patch" option to directly jump to the
per-hunk selection UI of the interactive mode.
* "git diff" and its family of commands learned --dirstat=0 to show
directories that contribute less than 0.1% of changes.
* "git diff" and its family of commands learned --dirstat=lines mode to
assess damage to the directory based on number of lines in the patch
output, not based on the similarity numbers.
* "git format-patch" learned "--quiet" option to suppress the output of
the names of generated files.
* "git format-patch" quotes people's names when it has RFC822 special
characters in it, e.g. "Junio C. Hamano" <jch@example.com>. Earlier
it was up to the user to do this when using its output.
* "git format-patch" can take an empty --subject-prefix now.
* "git grep" learned the "-P" option to take pcre regular expressions.
* "git log" and friends learned a new "--notes" option to replace the
"--show-notes" option. Unlike "--show-notes", "--notes=<ref>" does
not imply showing the default notes.
* They also learned a log.abbrevCommit configuration variable to augment
the --abbrev-commit command line option.
* "git ls-remote" learned "--exit-code" option to consider it a
different kind of error when no remote ref to be shown.
* "git merge" learned "-" as a short-hand for "the previous branch", just
like the way "git checkout -" works.
* "git merge" uses "merge.ff" configuration variable to decide to always
create a merge commit (i.e. --no-ff, aka merge.ff=no), refuse to create
a merge commit (i.e. --ff-only, aka merge.ff=only). Setting merge.ff=yes
(or not setting it at all) restores the default behaviour of allowing
fast-forward to happen when possible.
* p4-import (from contrib) learned a new option --preserve-user.
* "git read-tree -m" learned "--dry-run" option that reports if a merge
would fail without touching the index nor the working tree.
* "git rebase" that does not specify on top of which branch to rebase
the current branch now uses @{upstream} of the current branch.
* "git rebase" finished either normally or with --abort did not
update the reflog for HEAD to record the event to come back to
where it started from.
* "git remote add -t only-this-branch --mirror=fetch" is now allowed. Earlier
a fetch-mode mirror meant mirror everything, but now it only means refs are
not renamed.
* "git rev-list --count" used with "--cherry-mark" counts the cherry-picked
commits separately, producing more a useful output.
* "git submodule update" learned "--force" option to get rid of local
changes in submodules and replace them with the up-to-date version.
* "git status" and friends ignore .gitmodules file while the file is
still in a conflicted state during a merge, to avoid using information
that is not final and possibly corrupt with conflict markers.
Also contains various documentation updates and minor miscellaneous
changes.
Fixes since v1.7.5
------------------
Unless otherwise noted, all the fixes in 1.7.5.X maintenance track are
included in this release.
* "git config" used to choke with an insanely long line.
(merge ef/maint-strbuf-init later)
* "git diff --quiet" did not work well with --diff-filter.
(merge jk/diff-not-so-quick later)
* "git status -z" did not default to --porcelain output format.
(merge bc/maint-status-z-to-use-porcelain later)
