What's cooking in git.git (Apr 2012, #04; Tue, 10)
--------------------------------------------------
This issue describes the state of my tree in preparation for opening the
post 1.7.10 cycle. The 'next' branch has not been rewound yet, but it
soon will be. The Stalled topics will be discarded by default.
"git subtree" is in contrib/ now.
You can find the changes described here in the integration branches of the
repositories listed at
http://git-blame.blogspot.com/p/git-public-repositories.html
--------------------------------------------------
[New Topics]
* bw/submodule-sed-solaris (2012-04-09) 1 commit
- Avoid bug in Solaris xpg4/sed as used in submodule
Sensible.
Will merge to 'next'.
* cb/http-multi-curl-auth (2012-04-10) 2 commits
- fix http auth with multiple curl handles
- http auth fails with multiple curl handles
Fixes http authentication breakage when we keep multiple HTTP requests in
flight using curl-multi.
Peff may want to sign this off, but otherwise looked sensible.
* jk/rebase-i-submodule-conflict-only (2012-04-09) 1 commit
- rebase -i continue: don't skip commits that only change submodules
Giving "--continue" to a conflicted "rebase -i" session skipped a commit
that only results in changes to submodules.
Sensible.
Will merge to 'next'.
* ms/remote-usage-string (2012-04-09) 1 commit
- remote: update builtin usage
As an independent follow-up, we may want to rethink how the overall usage
string and subcommand usage strings are maintained.
Will merge to 'next'.
* pw/fast-import-dataref-parsing (2012-04-10) 1 commit
- fast-import: tighten parsing of datarefs
* pw/git-p4 (2012-04-09) 3 commits
- git p4: use "git p4" directly in tests
- git p4: update name in script
- git-p4: move to toplevel
Will merge to 'next'.
* rl/show-empty-prefix (2012-04-10) 1 commit
- rev-parse --show-prefix: add in trailing newline
Will merge to 'next'.
* tr/xdiff-fast-hash (2012-04-09) 1 commit
- xdiff: load full words in the inner loop of xdl_hash_record
--------------------------------------------------
[Stalled]
* lp/maint-diff-three-dash-with-graph (2012-03-20) 3 commits
- t4202: add test for "log --graph --stat -p" separator lines
- log --graph: fix break in graph lines
- log --graph --stat: three-dash separator should come after graph lines
With a review from Zbigniew, I have been expecting that this would be
rerolled, but that didn't happen.
Will discard shortly unless nothing happens.
* cn/apply-fix-ws-can-lengthen-lines (2012-03-11) 1 commit
. apply: reallocate the postimage buffer when needed
Attempts to address an ancient bug that dates back to the addition
of an oddball "tab-in-indent" whitespace breakage class that wants
to have longer lines than the original when fixing things up; broken
and results in double-frees.
Will discard shortly unless nothing happens.
* nd/columns (2012-03-13) 12 commits
- column: support grouping entries
- column: support "denser" mode
- ls-files: support --column
- tag: add --column
- column: support piping stdout to external git-column process
- status: add --column
- branch: add --column
- help: reuse print_columns() for help -a
- column: add dense layout support
- column: add columnar layout
- Stop starting pager recursively
- Add column layout skeleton and git-column
Modulo minor nits, looked nicer than the previous round and getting closer
to completion but nothing has happened recently.
Will discard shortly unless nothing happens.
* nd/threaded-index-pack (2012-03-11) 2 commits
- index-pack: support multithreaded delta resolving
- index-pack: split second pass obj handling into own function
Another reroll after a bugreport on pthread usage discovered by Ramsey,
but it seems the topic is cooking between Ramsay and Duy out of tree.
Will discard shortly unless nothing happens.
* jh/apply-free-patch (2012-03-28) 7 commits
- apply.c: WIP ownership audit
- apply: free unused fragments for submodule patch
- apply: free patch->result
- apply: release memory for fn_table
- apply: free patch->{def,old,new}_name fields
- apply: rename free_patch() to free_patch_list()
- apply: do not leak patches and fragments
Valgrind reports quite a lot of discarded memory inside apply. I started
auditing the memory ownership rules in the command, and am almost done.
* ss/git-svn-prompt-sans-terminal (2012-01-04) 3 commits
- fixup! 15eaaf4
- git-svn, perl/Git.pm: extend Git::prompt helper for querying users
- perl/Git.pm: "prompt" helper to honor GIT_ASKPASS and SSH_ASKPASS
The bottom one has been replaced with a rewrite based on comments
from Ævar. The second one needs more work, both in perl/Git.pm and
prompt.c, to give precedence to tty over SSH_ASKPASS when terminal
is available.
Will discard shortly unless nothing happens.
* jc/split-blob (2012-04-03) 7 commits
- chunked-object: streaming checkout
- chunked-object: fallback checkout codepaths
- bulk-checkin: support chunked-object encoding
- bulk-checkin: allow the same data to be multiply hashed
- new representation types in the packstream
- packfile: use varint functions
- varint: make it available outside the context of pack
(this branch is tangled with jc/index-v4.)
Not ready.
I finished the streaming checkout codepath, but as explained in
127b177 (bulk-checkin: support chunked-object encoding, 2011-11-30),
these are still early steps of a long and painful journey. At least
pack-objects and fsck need to learn the new encoding for the series
to be usable locally, and then index-pack/unpack-objects needs to
learn it to be used remotely.
Given that I heard a lot of noise that people want large files, and
that I was asked by somebody at GitTogether'11 privately for an
advice on how to pay developers (not me) to help adding necessary
support, I am somewhat dissapointed that the original patch series
that was sent almost two months ago still remains here without much
comments and updates from the developer community. I even made the
interface to the logic that decides where to split chunks easily
replaceable, and I deliberately made the logic in the original patch
extremely stupid to entice others, especially the "bup" fanboys, to
come up with a better logic, thinking that giving people an easy
target to shoot for, they may be encouraged to help out. The plan is
not working :-(.
--------------------------------------------------
[Cooking]
* jc/index-v4 (2012-04-04) 10 commits
- update-index: upgrade/downgrade on-disk index version
- read-cache.c: write prefix-compressed names in the index
- read-cache.c: read prefix-compressed names in index on-disk version v4
- read-cache.c: move code to copy incore to ondisk cache to a helper function
- read-cache.c: move code to copy ondisk to incore cache to a helper function
- read-cache.c: report the header version we do not understand
- read-cache.c: make create_from_disk() report number of bytes it consumed
- read-cache.c: allow unaligned mapping of the index file
- cache.h: hide on-disk index details
- varint: make it available outside the context of pack
(this branch is tangled with jc/split-blob.)
Trivially shrinks the on-disk size of the index file to save both I/O and
checksum overhead. The "v4" format represented here may not be what we
eventually want to have, but the preparatory refactoring steps and the way
how backward compatibility is retained should give plenty to learn to GSoC
student-hopefuls.
* jk/add-p-skip-conflicts (2012-04-05) 1 commit
- add--interactive: ignore unmerged entries in patch mode
Excludes conflicted paths from "add -p" processing, as it is not prepared
to handle them.
Will merge to 'next'.
* bw/spawn-via-shell-path (2012-04-03) 1 commit
- Use SHELL_PATH from build system in run_command.c:prepare_shell_cmd
"sh" on the user's PATH may be utterly broken on some systems;
consistently use SHELL_PATH even from inside run-command API.
Will merge to 'next'.
* jc/commit-unedited-template (2012-04-03) 5 commits
- Documentation/git-commit: rephrase the "initial-ness" of templates
- git-commit.txt: clarify -t requires editing message
- commit: rephrase the error when user did not touch templated log message
- commit: do not trigger bogus "has templated message edited" check
- t7501: test the right kind of breakage
When "git commit --template F" errors out because the user did not touch
the message, it claimed that it aborts due to "empty message", which was
utterly wrong.
Will merge to 'next'.
* jc/push-upstream-sanity (2012-04-05) 1 commit
- push: error out when the "upstream" semantics does not make sense
Fix broken 'push to upstream' implementation. "git push $there" without
refspec, when the current branch is set to push to a remote different from
$there, used to push to $there using the upstream information to a remote
unreleated to $there.
Will merge to 'next'.
* jk/http-backend-keep-committer-ident-env (2012-03-30) 1 commit
- http-backend: respect existing GIT_COMMITTER_* variables
The smart-http backend used to always override GIT_COMMITTER_* variables
with REMOTE_USER and REMOTE_ADDR.
Will merge to 'next'.
* mk/gitweb-diff-hl (2012-04-05) 8 commits
- gitweb: Refinement highlightning in combined diffs
- gitweb: Highlight interesting parts of diff
- gitweb: Push formatting diff lines to print_diff_chunk()
- gitweb: Use print_diff_chunk() for both side-by-side and inline diffs
- gitweb: Extract print_sidebyside_diff_lines()
- gitweb: Pass esc_html_hl_regions() options to esc_html()
- gitweb: esc_html_hl_regions(): Don't create empty <span> elements
- gitweb: Use descriptive names in esc_html_hl_regions()
Rerolled.
* it/fetch-pack-many-refs (2012-04-10) 4 commits
- remote-curl: main test case for the OS command line overflow
- fetch-pack: test cases for the new --stdin option
- remote-curl: send the refs to fetch-pack on stdin
- fetch-pack: new --stdin option to read refs from stdin
Will merge to 'next'.
* jn/debian-customizes-default-editor (2012-04-10) 2 commits
- var doc: advertise current DEFAULT_PAGER and DEFAULT_EDITOR settings
- var doc: default editor and pager are configurable at build time
Will merge to 'next'.
* rs/commit-list-sort-in-batch (2012-04-09) 3 commits
- revision: insert unsorted, then sort in prepare_revision_walk()
- commit: use mergesort() in commit_list_sort_by_date()

- push: teach --recurse-submodules the on-demand option
- Refactor submodule push check to use string list instead of integer
- Teach revision walking machinery to walk multiple times sequencially
* jk/branch-quiet (2012-03-26) 2 commits
- teach "git branch" a --quiet option
- checkout: suppress tracking message with "-q"
Even with "-q"uiet option, "checkout" used to report setting up tracking.
Also "branch" learns "-q"uiet option to squelch informational message.
Will merge to 'next'.
* jk/run-command-eacces (2012-04-05) 2 commits
- run-command: treat inaccessible directories as ENOENT
- compat/mingw.[ch]: Change return type of exec functions to int
When PATH contains an unreadable directory, alias expansion code did not
kick in, and failed with an error that said "git-subcmd" was not found.
Will merge to 'next'.
* jb/am-include (2012-03-28) 1 commit
- am: support --include option
Will merge to 'next'.
* jc/am-report-3way (2012-03-28) 1 commit
- am -3: list the paths that needed 3-way fallback
Will merge to 'next'.
* rs/combine-diff-zero-context-at-the-beginning (2012-03-25) 1 commit
- combine-diff: fix loop index underflow
Fixes an age old corner case bug in combine diff (only triggered with -U0
and the hunk at the beginning of the file needs to be shown).
Will merge to 'next'.
* sl/autoconf (2012-03-26) 3 commits
- configure: be more idiomatic
- configure: avoid some code repetitions thanks to m4_{push,pop}def
- configure: move definitions of private m4 macros before AC_INIT invocation
Updates our configure.ac to follow a better "autoconf" style.
Will merge to 'next'.
* wk/gitweb-snapshot-use-if-modified-since (2012-03-30) 3 commits
- gitweb: add If-Modified-Since handling to git_snapshot().
- gitweb: refactor If-Modified-Since handling
- gitweb: add `status` headers to git_feed() responses.
Makes 'snapshot' request to "gitweb" honor If-Modified-Since: header,
based on the commit date.
Will merge to 'next'.
* jk/diff-no-rename-empty (2012-03-23) 4 commits
- merge-recursive: don't detect renames of empty files
- teach diffcore-rename to optionally ignore empty content
- make is_empty_blob_sha1 available everywhere
- drop casts from users EMPTY_TREE_SHA1_BIN
Forbids rename detection logic from matching two empty files as renames
during merge-recursive to prevent mismerges.
Will merge to 'next'.
* th/difftool-diffall (2012-04-04) 8 commits
- difftool: print list of valid tools with '--tool-help'
- difftool: teach difftool to handle directory diffs
- difftool: eliminate setup_environment function
- difftool: stop appending '.exe' to git
- difftool: remove explicit change of PATH
- difftool: exit(0) when usage is printed
- difftool: add '--no-gui' option
- difftool: parse options using Getopt::Long
Rolls the two-directory-diff logic from diffall script (in contrib/) into
"git difftool" framework.
* jc/maint-clean-nested-worktree-in-subdir (2012-03-15) 2 commits
(merged to 'next' on 2012-03-20 at fb5485e)
+ clean: preserve nested git worktree in subdirectories
+ remove_dir_recursively(): Add flag for skipping removal of toplevel dir
(this branch is tangled with jh/notes-merge-in-git-dir-worktree.)
"git clean -d -f" (not "-d -f -f") is supposed to protect nested working
trees of independent git repositories that exist in the current project
working tree from getting removed, but the protection applied only to such
working trees that are at the top-level of the current project by mistake.
Will merge to 'next'.
* ct/advise-push-default (2012-03-26) 2 commits
(merged to 'next' on 2012-03-28 at 62764ae)
+ clean up struct ref's nonfastforward field
+ push: Provide situational hints for non-fast-forward errors
Breaks down the cases in which "git push" fails due to non-ff into three
categories, and gives separate advise messages. This should be a good
change regardless of mm/push-default-switch-warning topic.
Will merge to 'next'.
* nl/rebase-i-cheat-sheet (2012-03-20) 1 commit
(merged to 'next' on 2012-03-20 at 3092a2b)
+ rebase -i: remind that the lines are top-to-bottom
Will merge to 'next'.
* da/difftool-test (2012-03-19) 1 commit
(merged to 'next' on 2012-03-20 at 0ada7d4)
+ t7800: Test difftool passing arguments to diff
Makes sure "difftool" options can be given in any order.
Will merge to 'master'.
* jh/notes-merge-in-git-dir-worktree (2012-03-15) 4 commits
(merged to 'next' on 2012-03-20 at 0c1b1de)
+ notes-merge: Don't remove .git/NOTES_MERGE_WORKTREE; it may be the user's cwd
+ notes-merge: use opendir/readdir instead of using read_directory()
+ t3310: illustrate failure to "notes merge --commit" inside $GIT_DIR/
+ remove_dir_recursively(): Add flag for skipping removal of toplevel dir
(this branch is tangled with jc/maint-clean-nested-worktree-in-subdir.)
Running "notes merge --commit" failed to perform correctly when run
from any directory inside $GIT_DIR/. When "notes merge" stops with
conflicts, $GIT_DIR/NOTES_MERGE_WORKTREE is the place a user edits
to resolve it.
Will merge to 'master'.
* jn/diffstat-tests (2012-03-13) 7 commits
(merged to 'next' on 2012-03-20 at 8791b2f)
+ diffstat summary line varies by locale: miscellany
+ test: use numstat instead of diffstat in binary-diff test
+ test: use --numstat instead of --stat in "git stash show" tests
+ test: test cherry-pick functionality and output separately
+ test: modernize funny-names test style
+ test: use numstat instead of diffstat in funny-names test
+ test: use test_i18ncmp when checking --stat output
Some tests checked the "diff --stat" output when they do not have to,
which unnecessarily made things harder to verify under GETTEXT_POISON.
Will merge to 'master'.
* tr/maint-word-diff-regex-sticky (2012-03-14) 3 commits
(merged to 'next' on 2012-03-20 at b3f67cd)
+ diff: tweak a _copy_ of diff_options with word-diff
+ diff: refactor the word-diff setup from builtin_diff_cmd
+ t4034: diff.*.wordregex should not be "sticky" in --word-diff
The regexp configured with wordregex was incorrectly reused across
files.
Will merge to 'master'.
* zj/test-cred-helper-nicer-prove (2012-03-15) 2 commits
(merged to 'next' on 2012-03-20 at b675ec1)
+ t0303: resurrect commit message as test documentation
+ t0303: immediately bail out w/o GIT_TEST_CREDENTIAL_HELPER
Minor improvement to t0303.
Will merge to 'master'.
* jc/commit-hook-authorship (2012-03-11) 3 commits
(merged to 'next' on 2012-03-12 at 05ca7f8)
+ commit: pass author/committer info to hooks
+ t7503: does pre-commit-hook learn authorship?
+ ident.c: add split_ident_line() to parse formatted ident line
(this branch is tangled with jc/run-hook-env-1.)
"git commit --author=$name" did not tell the name that was being
recorded in the resulting commit to hooks, even though it does do so
when the end user overrode the authorship via the "GIT_AUTHOR_NAME"
environment variable.
Will merge to 'master'.
* jc/run-hook-env-1 (2012-03-11) 3 commits
- run_hook(): enhance the interface to pass arbitrary environment
+ t7503: does pre-commit-hook learn authorship?
+ ident.c: add split_ident_line() to parse formatted ident line
(this branch is tangled with jc/commit-hook-authorship.)
Not urgent.
Updates run_hook() API to be much less specific to "commit". It would
only be useful if people start doing more interesting things with hooks.
* jc/diff-algo-cleanup (2012-02-19) 2 commits
(merged to 'next' on 2012-03-15 at cca0032)
+ xdiff: PATIENCE/HISTOGRAM are not independent option bits
+ xdiff: remove XDL_PATCH_* macros
Resurrects the preparatory clean-up patches from another topic that was
discarded, as this would give a saner foundation to build on diff.algo
configuration option series.
Will merge to 'master'.
* rs/unpack-trees-leakfix (2012-03-06) 1 commit
(merged to 'next' on 2012-03-07 at 69a69cd)
+ unpack-trees: plug minor memory leak
Will sneak a fix-up under this one when I rebuild 'next' tomorrow.
* mm/push-default-switch-warning (2012-03-09) 1 commit
(merged to 'next' on 2012-03-28 at 074b16b)
+ push: start warning upcoming default change for push.default
This resurrects an ancient patch I wrote during a discussion we had in the
1.6.3-1.6.4 era. This should probably come after ct/advise-push-default
topic and at that point the advise messages need to be rephrased, taking
the future default change into account.
Will kick back to 'pu'.
* jc/fmt-merge-msg-people (2012-03-13) 1 commit
- fmt-merge-msg: show those involved in a merged series
The "fmt-merge-msg" command learns to list the primary contributors
involved in the side topic you are merging.
Will merge to 'next'.
* nl/http-proxy-more (2012-04-10) 6 commits
- fixup? 6e17b8c
(merged to 'next' on 2012-03-20 at c004001)
+ http: rename HTTP_REAUTH to HTTP_AUTH_RETRY
+ http: Avoid limit of retrying request only twice
+ http: handle proxy authentication failure (error 407)
+ http: handle proxy proactive authentication
+ http: try http_proxy env var when http.proxy config option is not set
The code to talk to http proxies learn to use the same credential
API used to talk to the final http destinations.
Will kick back to 'pu'.
* nd/stream-more (2012-03-07) 7 commits
(merged to 'next' on 2012-03-07 at 7325922)
+ update-server-info: respect core.bigfilethreshold
+ fsck: use streaming API for writing lost-found blobs
+ show: use streaming API for showing blobs
+ parse_object: avoid putting whole blob in core
+ cat-file: use streaming API to print blobs
+ Add more large blob test cases
+ streaming: make streaming-write-entry to be more reusable
Use API to read blob data in smaller chunks in more places to
reduce the memory footprint. In general, looked fairly good.
Will merge to 'master'.
