GIT v1.5.1 Release Notes
========================
Updates since v1.5.0
--------------------
* Deprecated commands and options.
- git-diff-stages and git-resolve have been removed.
* New commands and options.
- "git log" and friends take --reverse, which instructs them
to give their output in the order opposite from their usual.
They typically output from new to old, but with this option
their output would read from old to new. "git shortlog"
usually lists older commits first, but with this option,
they are shown from new to old.
- "git log --pretty=format:<string>" to allow more flexible
custom log output.
- "git diff" learned --ignore-space-at-eol. This is a weaker
form of --ignore-space-change.
- "git diff --no-index pathA pathB" can be used as diff
replacement with git specific enhancements.
- "git diff --no-index" can read from '-' (standard input).
- "git diff" also learned --exit-code to exit with non-zero
status when it found differences. In the future we might
want to make this the default but that would be a rather big
backward incompatible change; it will stay as an option for
now.
- "git diff --quiet" is --exit-code with output turned off,
meant for scripted use to quickly determine if there is any
tree-level difference.
- Textual patch generation with "git diff" without -w/-b
option has been significantly optimized. "git blame" got
faster because of the same change.
- "git log" and "git rev-list" has been optimized
significantly when they are used with pathspecs.
- "git branch --track" can be used to set up configuration
variables to help it easier to base your work on branches
you track from a remote site.
- "git format-patch --attach" now emits attachments. Use
--inline to get an inlined multipart/mixed.
- "git name-rev" learned --refs=<pattern>, to limit the tags
used for naming the given revisions only to the ones
matching the given pattern.
- "git remote update" is to run "git fetch" for defined remotes
to update tracking branches.
- "git cvsimport" can now take '-d' to talk with a CVS
repository different from what are recorded in CVS/Root
(overriding it with environment CVSROOT does not work).
- "git bundle" can help sneaker-netting your changes between
repositories.
- "git mergetool" can help 3-way file-level conflict
resolution with your favorite graphical merge tools.
- A new configuration "core.symlinks" can be used to disable
symlinks on filesystems that do not support them; they are
checked out as regular files instead.
- You can name a commit object with its first line of the
message. The syntax to use is ':/message text'. E.g.
$ git show ":/object name: introduce ':/<oneline prefix>' notation"
means the same thing as:
$ git show 28a4d940443806412effa246ecc7768a21553ec7
- "git bisect" learned a new command "run" that takes a script
to run after each revision is checked out to determine if it
is good or bad, to automate the bisection process.
* Updated behaviour of existing commands.
- "git fsck" does not barf on corrupt loose objects.
- "git archimport" allows remapping when coming up with git
branch names from arch names.
- git-svn got almost a rewrite.
- core.autocrlf configuration, when set to 'true', makes git
to convert CRLF at the end of lines in text files to LF when
reading from the filesystem, and convert in reverse when
writing to the filesystem. The variable can be set to
'input', in which case the conversion happens only while
reading from the filesystem but files are written out with
LF at the end of lines. Currently, which paths to consider
'text' (i.e. be subjected to the autocrlf mechanism) is
decided purely based on the contents, but the plan is to
allow users to explicitly override this heuristic based on
paths.
- The behaviour of 'git-apply', when run in a subdirectory,
without --index nor --cached were inconsistent with that of
the command with these options. This was fixed to match the
behaviour with --index. A patch that is meant to be applied
with -p1 from the toplevel of the project tree can be
applied with any custom -p<n> option. A patch that is not
relative to the toplevel needs to be applied with -p<n>
option with or without --index (or --cached).
- "git diff" outputs a trailing HT when pathnames have embedded
SP on +++/--- header lines, in order to help "GNU patch" to
parse its output. "git apply" was already updated to accept
this modified output format since ce74618d (Sep 22, 2006).
- "git cvsserver" runs hooks/update and honors its exit status.
- "git cvsserver" can be told to send everything with -kb.
- "git diff --check" also honors the --color output option.
- "git name-rev" used to stress the fact that a ref is a tag too
much, by saying something like "v1.2.3^0~22". It now says
"v1.2.3~22" in such a case (it still says "v1.2.3^0" if it does
not talk about an ancestor of the commit that is tagged, which
makes sense).
- "git rev-list --boundary" now shows boundary markers for the
commits omitted by --max-age and --max-count condition.
- The configuration mechanism now reads $(prefix)/etc/gitconfig.
- "git apply --verbose" shows what preimage lines were wanted
when it couldn't find them.
- "git status" in a read-only repository got a bit saner.
- "git fetch" (hence "git clone" and "git pull") are less
noisy when the output does not go to tty.
- "git fetch" between repositories with many refs were slow
even when there are not many changes that needed
transferring. This has been sped up by partially rewriting
the heaviest parts in C.
- "git mailinfo" which splits an e-mail into a patch and the
metainformation was rewritten, thanks to Don Zickus. It
handles nested multipart better.
- send-email learned configurable bcc and chain-reply-to.
- "git remote show $remote" also talks about branches that
would be pushed if you run "git push remote".
- Using objects from packs is now seriouly optimized by clever
use of a cache. This should be most noticeable in git-log
family of commands that involve reading many tree objects.
In addition, traversing revisions while filtering changes
with pathspecs is made faster by terminating the comparison
between the trees as early as possible.
* Hooks
- The part to send out notification e-mails was removed from
the sample update hook, as it was not an appropriate place
to do so.
* Others
- git-revert, git-gc and git-cherry-pick are now built-ins.
