What's cooking in git.git (Nov 2015, #03; Fri, 20)
--------------------------------------------------
Here are the topics that have been cooking. Commits prefixed with
'-' are only in 'pu' (proposed updates) while commits prefixed with
'+' are in 'next'.
Sorry for the extreme delay in pushing out my tree. I ended up busier
than I expected during the first week of Junio's absence, and then it
took me a while to dig myself out of the ever-filling hole of incoming
topics. :)
Expect quite a few new topics in this edition. A number of them have
seen review already, and I'm planning to merge them to "next" fairly
quickly (I may do another integration cycle late tonight or tomorrow
with those changes).
I still have a few threads to comb through on the list. If you don't see
the latest version of your topic here, please feel free to ping me, or
to repost.
You can find the normal integration branches at:
https://github.com/git/git/
and all topic branches at:
https://github.com/peff/git/
But note that I will _not_ be pushing to kernel.org.

--------------------------------------------------
[Graduated to "master"]
* dg/git-svn-empty-dirs (2015-11-05) 1 commit
- git-svn: improve rebase/mkdirs performance
This came via a pull from Eric's git-svn tree, and I dropped the
topic branch that Junio had created.
* dk/gc-idx-wo-pack (2015-11-04) 3 commits
(merged to 'next' on 2015-11-05 at af058fa)
+ gc: remove garbage .idx files from pack dir
+ t5304: test cleaning pack garbage
+ prepare_packed_git(): refactor garbage reporting in pack directory
Having a leftover .idx file without corresponding .pack file in
the repository hurts performance; "git gc" learned to prune them.
We may want to do the same for .bitmap (and notice but not prune
.keep) without corresponding .pack, but that can be a separate
topic.
* lf/ref-is-hidden-namespace (2015-11-05) 4 commits
(merged to 'next' on 2015-11-05 at b245404)
+ t5509: add basic tests for hideRefs
+ hideRefs: add support for matching full refs
+ upload-pack: strip refs before calling ref_is_hidden()
+ config.txt: document the semantics of hideRefs with namespaces
Extend transfer.hideRefs to work better with use of namespaces.
--------------------------------------------------
[Stalled]
* nd/ita-cleanup (2015-09-06) 6 commits
- grep: make it clear i-t-a entries are ignored
- checkout(-index): do not checkout i-t-a entries
- apply: make sure check_preimage() does not leave empty file on error
- apply: fix adding new files on i-t-a entries
- add and use a convenience macro ce_intent_to_add()
- blame: remove obsolete comment
Paths that have been told the index about with "add -N" are not yet
in the index, but various commands behaved as if they already are.
Some commits need better explanation.
Waiting for a reroll.
* ld/p4-detached-head (2015-09-09) 2 commits
- git-p4: work with a detached head
- git-p4: add failing test for submit from detached head
Will be rerolled.
($gmane/277574)
* mg/httpd-tests-update-for-apache-2.4 (2015-04-08) 2 commits
- t/lib-git-svn: check same httpd module dirs as lib-httpd
- t/lib-httpd: load mod_unixd
This is the first two commits in a three-patch series $gmane/266962
Becoming tired of waiting for a reroll.
with updated log message ($gmane/268061).
* wp/sha1-name-negative-match (2015-06-08) 2 commits
- sha1_name.c: introduce '^{/!-<negative pattern>}' notation
- test for '!' handling in rev-parse's named commits
Introduce "branch^{/!-<pattern>}" notation to name a commit
reachable from branch that does not match the given pattern.
Becoming tired of waiting for a reroll.
($gmane/271213).
* ak/format-patch-odir-config (2015-06-19) 1 commit
- format-patch: introduce format.outputDirectory configuration
Reroll exists but didn't pick it up as it seemed to be still
collecting review comments.
Becoming tired of waiting for a reroll.
($gmane/272180).
* jc/diff-b-m (2015-02-23) 5 commits
. WIPWIP
. WIP: diff-b-m
- diffcore-rename: allow easier debugging
- diffcore-rename.c: add locate_rename_src()
- diffcore-break: allow debugging
"git diff -B -M" produced incorrect patch when the postimage of a
completely rewritten file is similar to the preimage of a removed
file; such a resulting file must not be expressed as a rename from
other place.
The fix in this patch is broken, unfortunately.

[Cooking]
* dt/refs-backend-pre-vtable (2015-11-20) 10 commits
- refs: break out ref conflict checks
- files_log_ref_write: new function
- initdb: make safe_create_dir public
- refs: split filesystem-based refs code into a new file
- refs/refs-internal.h: new header file

- copy_msg(): rename to copy_reflog_msg()
- verify_refname_available(): new function
- verify_refname_available(): rename function
Code preparation for pluggable ref backends.
This is the slimmed-down version from Michael, v8. It applies a lot
more pleasantly than the old one.
Will merge to 'next'.
* rc/configure-use-libs-when-checking-a-lib (2015-11-06) 1 commit
(merged to 'next' on 2015-11-20 at 37c26aa)
+ configure.ac: use $LIBS not $CFLAGS when testing -lpthread
The "configure" script did not test for -lpthread correctly, which
upset some linkers.
Will merge to 'master'.
* ad/sha1-update-chunked (2015-11-05) 2 commits
- sha1: allow limiting the size of the data passed to SHA1_Update()
- sha1: provide another level of indirection for the SHA-1 functions
Apple's common crypto implementation of SHA1_Update() does not take
more than 4GB at a time, and we now have a compile-time workaround
for it.
Will merge to 'next'.
* vl/grep-configurable-threads (2015-11-01) 1 commit
- grep: add --threads=<num> option and grep.threads configuration
"git grep" can now be configured (or told from the command line)
how many threads to use when searching in the working tree files.
I haven't reviewed v6 yet. More eyes are welcome.
* kf/http-proxy-auth-methods (2015-11-04) 3 commits
. SQUASH???
. http: use credential API to handle proxy authentication
. http: allow selection of proxy authentication method
New http.proxyAuthMethod configuration variable can be used to
specify what authentication method to use, as a way to work around
proxies that do not give error response expected by libcurl when
CURLAUTH_ANY is used. Also, the codepath for proxy authentication
has been taught to use credential API to store the authentication
material in user's keyrings.
I ejected this from pu for the moment, as it conflicts with the
pt/http-socks-proxy topic.
Still being worked on.
($gmane/280925).
* fp/subtree-todo-update (2015-11-06) 1 commit
(merged to 'next' on 2015-11-20 at 3861698)
+ contrib/subtree: remove "push" command from the "todo" file
Will merge to 'master'.
* sb/submodule-parallel-update (2015-11-20) 11 commits
- clone: allow an explicit argument for parallel submodule clones
- submodule update: expose parallelism to the user
- git submodule update: have a dedicated helper for cloning
- fetching submodules: respect `submodule.jobs` config option
- submodule-config: introduce parse_generic_submodule_config
- submodule-config: remove name_and_item_from_var
- submodule-config: drop check against NULL
- submodule-config: keep update strategy around
- run_processes_parallel: delimit intermixed task output
- Merge branch 'rs/daemon-plug-child-leak' into sb/submodule-parallel-update
- Merge branch 'sb/submodule-parallel-fetch' into sb/submodule-parallel-update
(this branch uses sb/submodule-parallel-fetch.)
Builds on top of the "fetch --recurse-submodules" work to introduce
parallel downloading into multiple submodules for "submodule update".
Waiting for sb/submodule-parallel-fetch to stabilize.
It would be the cleanest to rebuild sb/submodule-parallel-fetch on
top of 2.7.0 once it ships and then build this directly on top;
that way, we do not have to have merges in this topic that
distracting (besides, some part of the other topic can be updated
in-place instead of this follow-up topic tweaking them as past
mistakes and inflexibilities).
I picked up v4 from the list, but it needs review.
* jc/strbuf-gets (2015-10-28) 17 commits
- test-sha1-array: read command stream with strbuf_gets()
- grep: read -f file with strbuf_gets()
- send-pack: read list of refs with strbuf_gets()
- column: read lines with strbuf_gets()
- cat-file: read batch stream with strbuf_gets()

- check-attr, check-ignore, checkout-index: read paths with strbuf_gets()
- strbuf: add strbuf_gets()
Teach codepaths that communicate with users by reading text files
to be more lenient to editors that write CRLF-terminated lines.
Note that this is only about communication with Git, like feeding
list of object names from the standard input instead of from the
command line, and does not involve files in the working tree.
Waiting for reviews.
* eg/p4-submit-catch-failure (2015-10-30) 1 commit
- git-p4: clean up after p4 submit failure
Just like the working tree is cleaned up when the user cancelled
submission in P4Submit.applyCommit(), clean up the mess if "p4
submit" fails.
Needs an update to test.
($gmane/280539)
* ep/ident-with-getaddrinfo (2015-10-30) 1 commit
- (NEEDSWORK $gmane/280507) ident.c: add support for IPv6
A build without NO_IPv6 used to use gethostbyname() when guessing
user's hostname, instead of getaddrinfo() that is used in other
codepaths in such a build.
Waiting for a reroll.
($gmane/280507)
* jc/test-must-fail-with-sigpipe (2015-10-30) 1 commit
. test: accept death by SIGPIPE as a valid failure mode
Discarded in favor of ls/test-must-fail-sigpipe.
* pt/http-socks-proxy (2015-11-20) 1 commit
(merged to 'next' on 2015-11-20 at dc6ae48)
+ remote-http(s): support SOCKS proxies
Add support for talking http/https over socks proxy.
Will cook in 'next'.
* mh/notes-allow-reading-treeish (2015-10-08) 3 commits
(merged to 'next' on 2015-10-23 at 8a697f0)
+ notes: allow treeish expressions as notes ref
+ Merge branch 'jk/notes-dwim-doc' into next
+ Merge branch 'jc/merge-drop-old-syntax' into next
(this branch uses jc/merge-drop-old-syntax.)
Some "git notes" operations, e.g. "git log --notes=<note>", should
be able to read notes from any tree-ish that is shaped like a notes
tree, but the notes infrastructure required that the argument must
be a ref under refs/notes/. Loosen it to require a valid ref only
when the operation would update the notes (in which case we must
have a place to store the updated notes tree, iow, a ref).
As the patch was done on top of the 'drop old-syntax from merge',
this has to wait until that other topic can graduate, unfortunately.
It can be redone in a way that does not depend on that topic after
this cycle, though.
Will keep in 'next'.
* jc/mailinfo (2015-10-21) 1 commit
- mailinfo: ignore in-body header that we do not care about
Some people write arbitrary garbage at the beginning of a piece of
e-mail (or after -- >8 -- scissors -- >8 -- line) in the commit log
message and expect them to be discarded, even though "From:" and
"Subject:" are the only documented in-body headers that you are
supposed to have there. Allow some garbage (specifically, what may
look like RFC2822 headers like "MIME-Version: ...") to be there and
ignore them.
I have a feeling that that this is a step in a wrong direction.
Comments?
* js/am-3-merge-recursive-direct (2015-10-12) 2 commits
(merged to 'next' on 2015-10-23 at dc631e5)
+ am: make a direct call to merge_recursive
+ merge_recursive_options: introduce the "gently" flag
The merge_recursive_generic() function has been made a bit safer to
call from inside a process. "git am -3" was taught to make a direct
call to the function when falling back to three-way merge.
Being able to make a direct call would be good in general, but as a
performance thing, we would want to see it backed up by numbers.
I haven't gone through the "gently" change with fine toothed comb;
I can see that the change avoids calling die(), but I haven't made
sure that the program states (e.g. what's in the in-core index) are
adjusted sensibly when it returns to the caller instead of dying,
or the codepaths that used to die() are free of resource leaks.
The original code certainly did not care the program states at the
point of dying exactly because it knew it is going to exit, but now
they have to care, and they need to be audited.
Will keep in 'next'.
* sg/pretty-more-date-mode-format (2015-10-07) 1 commit
- pretty: add format specifiers for short and raw date formats
Introduce "%as" and "%aR" placeholders for "log --format" to show
the author date in the short and raw formats.
I have a feeling that that this is a step in a wrong direction.
Comments?
* kn/for-each-branch-remainder (2015-10-02) 9 commits
- branch: implement '--format' option
- branch: use ref-filter printing APIs
- ref-filter: make %(upstream:track) prints "[gone]" for invalid upstreams
- ref-filter: introduce format_ref_array_item()
- ref-filter: adopt get_head_description() from branch.c
- ref-filter: modify "%(objectname:short)" to take length
- ref-filter: add support for %(path) atom
- ref-filter: implement %(if:equals=<string>) and %(if:notequals=<string>)
- ref-filter: implement %(if), %(then), and %(else) atoms
More unification among "branch -l", "tag -l" and "for-each-ref --format".
Expecting a reroll.
($gmane/278926)
* jk/graph-format-padding (2015-09-14) 1 commit
- pretty: pass graph width to pretty formatting for use in '%>|(N)'
Redefine the way '%>|(N)' padding and the "--graph" option
interacts. It has been that the available columns to display the
log message was measured from the edge of the area the graph ended,
but with this it becomes the beginning of the entire output.
I have a suspicion that 50% of the users would appreciate this
change, and the remainder see this break their expectation. If
that is the case, we might need to introduce a similar but
different alignment operator so that this new behaviour is
available to those who want to use it, without negatively affecting
existing uses.
Undecided.
($gmane/278326)
* sb/submodule-parallel-fetch (2015-11-05) 16 commits
(merged to 'next' on 2015-11-20 at 89fc723)
+ strbuf: update documentation for strbuf_read_once()
+ run-command: remove set_nonblocking()
(merged to 'next' on 2015-10-23 at 8f04bbd)
+ run-command: fix missing output from late callbacks
+ test-run-command: increase test coverage
+ test-run-command: test for gracefully aborting
+ run-command: initialize the shutdown flag
+ run-command: clear leftover state from child_process structure
+ run-command: fix early shutdown
(merged to 'next' on 2015-10-15 at df63590)
+ submodules: allow parallel fetching, add tests and documentation
+ fetch_populated_submodules: use new parallel job processing
+ run-command: add an asynchronous parallel child processor
+ sigchain: add command to pop all common signals
+ strbuf: add strbuf_read_once to read without blocking
+ xread_nonblock: add functionality to read from fds without blocking
+ xread: poll on non blocking fds
+ submodule.c: write "Fetching submodule <foo>" to stderr
(this branch is used by sb/submodule-parallel-update.)
Add a framework to spawn a group of processes in parallel, and use
it to run "git fetch --recurse-submodules" in parallel.
I merged the removal of the non-blocking descriptors to 'next'.
Will cook in 'next'.
* ad/cygwin-wants-rename (2015-08-07) 1 commit
- config.mak.uname: Cygwin needs OBJECT_CREATION_USES_RENAMES
Will hold.
($gmane/275680).
* jc/rerere-multi (2015-09-14) 7 commits
- rerere: do use multiple variants
- t4200: rerere a merge with two identical conflicts
- rerere: allow multiple variants to exist
- rerere: delay the recording of preimage
- rerere: handle leftover rr-cache/$ID directory and postimage files
- rerere: scan $GIT_DIR/rr-cache/$ID when instantiating a rerere_id
- rerere: split conflict ID further
"git rerere" can encounter two or more files with the same conflict
signature that have to be resolved in different ways, but there was
no way to record these separate resolutions.
* jc/merge-drop-old-syntax (2015-04-29) 1 commit
(merged to 'next' on 2015-10-07 at 50fed71)
+ merge: drop 'git merge <message> HEAD <commit>' syntax
(this branch is used by mh/notes-allow-reading-treeish.)
Originally merged to 'next' on 2015-05-28
Stop supporting "git merge <message> HEAD <commit>" syntax that has
been deprecated since October 2007. It has been reported that
git-gui still uses the deprecated syntax, which needs to be fixed
before this final step can proceed.
Will keep in 'next'.
