UI, Workflows & Features
+ * A new mode for push, "simple", which is a cross between "current"
+ and "upstream", has been introduced. "git push" without any refspec
+ will push the current branch out to the same name at the remote
+ repository only when it is set to track the branch with the same
+ name over there. The plan is to make this mode the new default
+ value when push.default is not configured.
+
+ * A couple of commands learned the "--column" option to produce
+ columnar output.
+
* A third-party tool "git subtree" is distributed in contrib/
* Error messages given when @{u} is used for a branch without its
tracking. Also "branch" learned the "-q"uiet option to squelch
informational message.
+ * Your build platform may support hardlinks but you may prefer not to
+ use them, e.g. when installing to DESTDIR to make a tarball and
+ untarring on a filesystem that has poor support for hardlinks.
+ There is a Makefile option NO_INSTALL_HARDLINKS for you.
+
* The smart-http backend used to always override GIT_COMMITTER_*
variables with REMOTE_USER and REMOTE_ADDR, but these variables are
now preserved when set.
needed such treatment are now reported to the end user, so that the
result in them can be eyeballed with extra care.
+ * The output from "diff/log --stat" used to always allocate 4 columns
+ to show the number of modified lines, but not anymore.
+
+ * "git difftool" learned the "--dir-diff" option to spawn external
+ diff tools that can compare two directory hierarchies at a time
+ after populating two temporary directories, instead of running an
+ instance of the external tool once per a file pair.
+
* The "fmt-merge-msg" command learns to list the primary contributors
involved in the side topic you are merging.
- * The cases "git push" fails due to non-ff can be broken into three
- categories; each case is given a separate advise message.
+ * "git rebase" learned to optionally keep commits that do not
+ introduce any change in the original history.
* "git push --recurse-submodules" learned to optionally look into the
histories of submodules bound to the superproject and push them
* "git svn" used to die with unwanted SIGPIPE when talking with HTTP
server that uses keep-alive.
- * "git p4" has been moved out of contrib/ area.
+ * "git svn" learned to use platform specific authentication
+ providers, e.g. gnome-keyring, kwallet, etc.
+
+ * "git p4" has been moved out of contrib/ area and has seen more work
+ on importing labels as tags from (and exporting tags as labels to)
+ p4.
-Performance
+Performance and Internal Implementation (please report possible regressions)
+
+ * An experimental "version 4" format of the index file has been
+ introduced to reduce on-disk footprint and I/O overhead.
+
+ * "git archive" learned to produce its output without reading the
+ blob object it writes out in memory in its entirety.
+
+ * "git index-pack" that runs when fetching or pushing objects to
+ complete the packfile on the receiving end learned to use multiple
+ threads to do its job when available.
+
+ * The code to compute hash values for lines used by the internal diff
+ engine was optimized on little-endian machines, using the same
+ trick the kernel folks came up with.
* "git apply" had some memory leaks plugged.
one-by-one. Now they are collected in the queue unordered first,
and sorted immediately before getting used.
-Internal Implementation (please report possible regressions)
-
- * "git rev-parse --show-prefix" used to emit nothing when run at the
- top-level of the working tree, but now it gives a blank line.
-
- * Minor memory leak during unpack_trees (hence "merge" and "checkout"
- to check out another branch) has been plugged.
-
* More lower-level commands learned to use the streaming API to read
from the object store without keeping everything in core.
releases are contained in this release (see release notes to them for
details).
- * The i18n of error message "git stash save" was not properly done.
- (merge ed3c400 rl/maint-stash-i18n-save-error later to maint).
-
- * The report from "git fetch" said "new branch" even for a non branch
- ref.
- (merge 0997ada mb/fetch-call-a-non-branch-a-ref later to maint).
-
- * The "diff --no-index" codepath used limited-length buffers, risking
- pathnames getting truncated. Update it to use the strbuf API.
- (merge 875b91b jm/maint-strncpy-diff-no-index later to maint).
-
- * The parser in "fast-import" did not diagnose ":9" style references
- that is not followed by required SP/LF as an error.
- (merge 06454cb pw/fast-import-dataref-parsing later to maint).
-
- * When "git fetch" encounters repositories with too many references,
- the command line of "fetch-pack" that is run by a helper
- e.g. remote-curl, may fail to hold all of them. Now such an
- internal invocation can feed the references through the standard
- input of "fetch-pack".
- (merge 7103d25 it/fetch-pack-many-refs later to maint).
-
- * "git fetch" that recurses into submodules on demand did not check
- if it needs to go into submodules when non branches (most notably,
- tags) are fetched.
- (merge a6801ad jl/maint-submodule-recurse-fetch later to maint).
-
- * "git blame" started missing quite a few changes from the origin
- since we stopped using the diff minimalization by default in v1.7.2
- era.
- (merge 059a500 jc/maint-blame-minimal later to maint).
-
- * "log -p --graph" used with "--stat" had a few formatting error.
- (merge e2c5966 lp/maint-diff-three-dash-with-graph later to maint).
-
- * Giving "--continue" to a conflicted "rebase -i" session skipped a
- commit that only results in changes to submodules.
- (merge a6754cd jk/rebase-i-submodule-conflict-only later to maint).
+ * When a submodule repository uses alternate object store mechanism,
+ some commands that were started from the superproject did not
+ notice it and failed with "No such object" errors. The subcommands
+ of "git submodule" command that properly recursed into the
+ submodule in a separate process were OK; only the ones that cheated
+ and peeked directly into the submodule's repository from the
+ primary process were affected.
+ (merge 5e73633 hv/submodule-alt-odb later to maint).
+
+ * The directory path used in "git diff --no-index", when it recurses
+ down, was broken with a recent update after v1.7.10.1 release.
+ (merge 176a335 bp/diff-no-index-strbuf-fix later to maint).
+
+ * "git status --porcelain" ignored "--branch" option by mistake. The
+ output for "git status --branch -z" was also incorrect and did not
+ terminate the record for the current branch name with NUL as asked.
+ (merge d4a6bf1 jk/maint-status-porcelain-z-b later to maint).
+
+ * "git diff --stat" used to fully count a binary file with modified
+ execution bits whose contents is unmodified, which was not quite
+ right.
