What's cooking in git.git (Jan 2015, #05; Tue, 27)
--------------------------------------------------

Here are the topics that have been cooking.  Commits prefixed with
'-' are only in 'pu' (proposed updates) while commits prefixed with
'+' are in 'next'.

Hopefully final release candidate 2.3-rc2 has been tagged.  Please
spend some time to find and fix regressions, instead of spending all
time having fun with new and shiny toys.  The final hopefully will
happen sometime next week.

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

[Graduated to "master"]

* ak/cat-file-clean-up (2015-01-13) 1 commit
  (merged to 'next' on 2015-01-15 at bb1a4b3)
 + cat-file: use "type" and "size" from outer scope


* js/t1050 (2015-01-14) 1 commit
  (merged to 'next' on 2015-01-15 at f010b00)
 + t1050-large: generate large files without dd

--------------------------------------------------
[New Topics]

* jc/apply-ws-fix-expands-report (2015-01-22) 1 commit
 - apply: detect and mark whitespace errors in context lines when fixing
 (this branch uses jc/apply-ws-fix-expands.)

 "git apply --whitespace=fix" fixed whitespace errors in the common
 context lines but did so without reporting.

 Will merge to 'next'.


* ks/rebase-i-abbrev (2015-01-22) 1 commit
 - rebase -i: use full object name internally throughout the script

 The insn sheet "git rebase -i" creates did not fully honor
 core.abbrev settings.

 Will merge to 'next'.


* mh/deref-symref-over-helper-transport (2015-01-21) 1 commit
 - transport-helper: do not request symbolic refs to remote helpers

 "git fetch" over a remote-helper that cannot respond to "list"
 command could not fetch from a symbolic reference e.g. HEAD.

 Will merge to 'next'.


* ak/add-i-empty-candidates (2015-01-22) 1 commit
 - add -i: return from list_and_choose if there is no candidate

 The interactive "show a list and let the user choose from it"
 interface "add -i" used showed and prompted to the user even when
 the candidate list was empty, against which the only "choice" the
 user could have made was to choose nothing.

 Will merge to 'next'.


* av/wincred-with-at-in-username-fix (2015-01-25) 1 commit
 - wincred: fix get credential if username has "@"

 Will merge to 'next'.


* jc/conf-var-doc (2015-01-27) 3 commits
 - CodingGuidelines: describe naming rules for configuration variables
 - config.txt: mark deprecated variables more prominently
 - config.txt: clarify that add.ignore-errors as deprecated

 Need to send this out for review before doing anything to it.


* jc/doc-log-rev-list-options (2015-01-23) 1 commit
 - Documentation: what does "git log --indexed-objects" even mean?

 Will merge to 'next'.


* jk/dumb-http-idx-fetch-fix (2015-01-27) 1 commit
 - dumb-http: do not pass NULL path to parse_pack_index

 Will merge to 'next'.


* ld/p4-submit-hint (2015-01-23) 1 commit
  (merged to 'next' on 2015-01-23 at ed972d3)
 + git-p4: correct --prepare-p4-only instructions

 Will merge to 'master' after 2.3 final.


* mg/commit-author-no-match-malformed-message (2015-01-26) 1 commit
 - commit: reword --author error message

 Will merge to 'next'.


* mg/push-repo-option-doc (2015-01-27) 1 commit

 Will merge to 'next'.


--------------------------------------------------
[Stalled]

* jn/doc-api-errors (2014-12-04) 1 commit
 - doc: document error handling functions and conventions

 For discussion.


* pw/remote-set-url-fetch (2014-11-26) 1 commit
 - remote: add --fetch and --both options to set-url

 Expecting a reroll.


* ms/submodule-update-config-doc (2014-11-03) 1 commit
 - submodule: clarify documentation for update subcommand

 Needs a reroll ($gmane/259037).


* je/quiltimport-no-fuzz (2014-10-21) 2 commits
 - git-quiltimport: flip the default not to allow fuzz
 - git-quiltimport.sh: allow declining fuzz with --exact option

 "quiltimport" drove "git apply" always with -C1 option to reduce
 context of the patch in order to give more chance to somewhat stale
 patches to apply.  Add an "--exact" option to disable, and also
 "-C$n" option to customize this behaviour.  The top patch
 optionally flips the default to "--exact".

 Tired of waiting for an Ack; will discard.


* tr/remerge-diff (2014-11-10) 9 commits
 - t4213: avoid "|" in sed regexp
 - log --remerge-diff: show what the conflict resolution changed
 - name-hash: allow dir hashing even when !ignore_case
 - merge-recursive: allow storing conflict hunks in index
 - merge_diff_mode: fold all merge diff variants into an enum
 - combine-diff: do not pass revs->dense_combined_merges redundantly
 - merge-recursive: -Xindex-only to leave worktree unchanged
 - merge-recursive: internal flag to avoid touching the worktree
 - merge-recursive: remove dead conditional in update_stages()

 "log -p" output learns a new way to let users inspect a merge
 commit by showing the differences between the automerged result
 with conflicts the person who recorded the merge would have seen
 and the final conflict resolution that was recorded in the merge.

 Waiting for a reroll ($gmane/256591).


* hv/submodule-config (2014-11-11) 4 commits
 - do not die on error of parsing fetchrecursesubmodules option
 - use new config API for worktree configurations of submodules
 - extract functions for submodule config set and lookup
 - implement submodule config cache for lookup of submodule names

 Kicked back to 'pu' per request ($gmane/255610).


* ab/add-interactive-show-diff-func-name (2014-05-12) 2 commits
 - SQUASH??? git-add--interactive: Preserve diff heading when splitting hunks
 - git-add--interactive: Preserve diff heading when splitting hunks

 Waiting for a reroll.


* jn/gitweb-utf8-in-links (2014-05-27) 1 commit
 - gitweb: Harden UTF-8 handling in generated links

 $gmane/250758?


* ss/userdiff-update-csharp-java (2014-06-02) 2 commits
 - userdiff: support Java try keyword
 - userdiff: support C# async methods and correct C# keywords

 Reviews sent; waiting for a response.


* bg/rebase-off-of-previous-branch (2014-04-16) 1 commit
 - git-rebase: print name of rev when using shorthand

 Teach "git rebase -" to report the concrete name of the branch
 (i.e. the previous one).

 But it stops short and does not do the same for "git rebase @{-1}".
 Expecting a reroll.


* rb/merge-prepare-commit-msg-hook (2014-01-10) 4 commits
 - merge: drop unused arg from abort_commit method signature
 - merge: make prepare_to_commit responsible for write_merge_state
 - t7505: ensure cleanup after hook blocks merge
 - t7505: add missing &&

 Expose more merge states (e.g. $GIT_DIR/MERGE_MODE) to hooks that
 run during "git merge".  The log message stresses too much on one
 hook, prepare-commit-msg, but it would equally apply to other hooks
 like post-merge, I think.

 Waiting for a reroll.


* jc/graph-post-root-gap (2013-12-30) 3 commits
 - WIP: document what we want at the end
 - graph: remove unused code a bit
 - graph: stuff the current commit into graph->columns[]

 This was primarily a RFH ($gmane/239580).


* tg/perf-lib-test-perf-cleanup (2013-09-19) 2 commits
 - perf-lib: add test_perf_cleanup target
 - perf-lib: split starting the test from the execution

 Add test_perf_cleanup shell function to the perf suite, that allows
 the script writers to define a test with a clean-up action.

 Will hold.


* jc/show-branch (2014-03-24) 5 commits
 - show-branch: use commit slab to represent bitflags of arbitrary width
 - show-branch.c: remove "all_mask"
 - show-branch.c: abstract out "flags" operation
 - show-branch.c: lift all_mask/all_revs to a global static
 - show-branch.c: update comment style

 Waiting for the final step to lift the hard-limit before sending it out.

--------------------------------------------------
[Cooking]

* ye/http-accept-language (2015-01-27) 2 commits
 - SQUASH???
 - http: Add Accept-Language header if possible

 Using environment variable LANGUAGE and friends on the client side,
 send Accept-Language when making HTTP requests.

 Almost there, I would think.


* ak/typofixes (2015-01-21) 2 commits
  (merged to 'next' on 2015-01-22 at e36f25a)
 + t/lib-terminal.sh: fix typo
 + pack-bitmap: fix typo

 Will merge to 'master'.


* jc/apply-ws-fix-expands (2015-01-22) 3 commits
 - apply: count the size of postimage correctly
 - apply: make update_pre_post_images() sanity check the given postlen
 - apply.c: typofix
 (this branch is used by jc/apply-ws-fix-expands-report.)

 "git apply --whitespace=fix" used to under-allocate the memory
 when the fix resulted in a longer text than the original patch.

 Will merge to 'next'.


* jc/coding-guidelines (2015-01-15) 1 commit
  (merged to 'next' on 2015-01-22 at 3c96639)
 + CodingGuidelines: clarify C #include rules

 Will merge to 'master'.


* jc/pretty-format-doc (2015-01-15) 1 commit
  (merged to 'next' on 2015-01-22 at 2a81ecc)
 + "log --pretty" documentation: do not forget "tformat:"

 Will cook in 'next'.


* jc/unused-symbols (2015-01-15) 8 commits
  (merged to 'next' on 2015-01-22 at 77fd5f0)
 + shallow.c: make check_shallow_file_for_update() static
 + remote.c: make clear_cas_option() static
 + urlmatch.c: make match_urls() static
 + revision.c: make save_parents() and free_saved_parents() static
 + line-log.c: make line_log_data_init() static
 + pack-bitmap.c: make pack_bitmap_filename() static
 + prompt.c: remove git_getpass() nobody uses
 + http.c: make finish_active_slot() and handle_curl_result() static

 Mark file-local symbols as "static", and drop functions that nobody
 uses.

 Will cook in 'next'.


* jk/sanity (2015-01-27) 3 commits
 - test-lib.sh: set prerequisite SANITY by testing what we really need
 - tests: correct misuses of POSIXPERM
 - t/lib-httpd: switch SANITY check for NOT_ROOT

 Waiting for ack or counter-proposal from Torsten.
 Otherwise looking good.

 - t7004: rename ULIMIT test prerequisite to ULIMIT_STACK_SIZE
 - update-ref: test handling large transactions properly
 (this branch uses mh/reflog-expire and sb/atomic-push.)

 I had to wiggle this in and am not confident I did it correctly.

 Need extra set of eyes to review this.

 - strbuf.h: group documentation for trim functions
 - strbuf.h: drop boilerplate descriptions of strbuf_split_*
 - strbuf.h: reorganize api function grouping headers

 Resolve the "doc vs header" to favor the latter.


* ah/usage-strings (2015-01-14) 1 commit
  (merged to 'next' on 2015-01-22 at bfa5bab)
 + standardize usage info string format

 After attempting and failing a password-less authentication
 (e.g. kerberos), libcURL refuses to fall back to password based
 Basic authentication without a bit of help/encouragement.

 Will cook in 'next'.

  (merged to 'next' on 2015-01-12 at 6b4605b)
 + format-patch: ignore diff.submodule setting
 + t4255: test am submodule with diff.submodule

 Setting diff.submodule to 'log' made "git format-patch" produce
 broken patches.

 Will cook in 'next'.

 - attr: avoid heavy work when we know the specified attr is not defined
 - attr: do not attempt to expand when we know it's not a macro

  (merged to 'next' on 2015-01-12 at 313c449)
 + rerere: error out on autoupdate failure

 "git rerere" (invoked internally from many mergy operations) did
 not correctly signal errors when told to update the working tree
 files and failed to do so for whatever reason.

 Will cook in 'next'.


* sb/atomic-push (2015-01-14) 11 commits
  (merged to 'next' on 2015-01-14 at 12c4e28)

 (this branch is used by sb/atomic-push-fix; uses mh/reflog-expire.)

 "git push" has been taught a "--atomic" option that makes push to
 update more than one ref an "all-or-none" affair.

 Will cook in 'next'.

 + refs.c: make ref_transaction_create a wrapper for ref_transaction_update
 (this branch is used by sb/atomic-push and sb/atomic-push-fix.)

 Restructure "reflog expire" to fit the reflogs better with the
 recently updated ref API.

 Looked reasonable (except that some shortlog entries stood out like
 a sore thumb).

 Will cook in 'next'.


* jc/push-to-checkout (2015-01-08) 2 commits
  (merged to 'next' on 2015-01-12 at e64df63)
 + receive-pack: support push-to-checkout hook
 + receive-pack: refactor updateInstead codepath

 Extending the js/push-to-deploy topic, the behaviour of "git push"
 when updating the working tree and the index with an update to the
 branch that is checked out can be tweaked by push-to-checkout hook.

 whistles.

 Some comments seen on the list; may be gaining some interests?

 - t2026 needs procondition SANITY
 - git-checkout.txt: a note about multiple checkout support for submodules

[Discarded]

* jc/push-cert-hmac-optim (2014-09-25) 2 commits
 . receive-pack: truncate hmac early and convert only necessary bytes
 . sha1_to_hex: split out "hex-format n bytes" helper and use it

 This is "we could do this if we wanted to", not "we measured and it
 improves performance critical codepath".


* mt/patch-id-stable (2014-06-10) 1 commit
 . patch-id: change default to stable

 Nobody seems to be jumping up & down requesting this last step,
 which makes the result somewhat backward incompatible.


* sb/copy-fd-errno (2014-11-17) 1 commit
 . copy.c: make copy_fd preserve meaningful errno


* cj/grep-none-match (2015-01-06) 1 commit
 . git-log: added --none-match option

 "git log --none-match --grep=WIP" will show only commits that are
 not marked as WIP.

 cj/log-invert-grep replaces this.


* lf/blame-commit-label (2015-01-12) 1 commit
 . blame.c: fix garbled error message

 jk/blame-commit-label replaces this.
