What's cooking in git.git (Feb 2015, #04; Tue, 17)

What's cooking in git.git (Feb 2015, #04; Tue, 17)

[Junio C Hamano]

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

The second batch of topics have been merged to 'master'.  I am
tempted to start discarding topics in the Stalled category that
haven't seen much reviews and discussions on for a long time.

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/add-i-empty-candidates (2015-01-22) 1 commit
  (merged to 'next' on 2015-02-12 at 0d3cc64)
 + 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.


* jc/apply-ws-fix-expands (2015-01-22) 3 commits
  (merged to 'next' on 2015-02-12 at 9a45b66)
 + 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.


* jc/diff-format-doc (2015-01-28) 1 commit
  (merged to 'next' on 2015-02-12 at 72a018a)
 + diff-format doc: a score can follow M for rewrite

 The documentation incorrectly said that C(opy) and R(ename) are the
 only ones that can be followed by the score number in the output in
 the --raw format.


* jc/doc-log-rev-list-options (2015-01-23) 1 commit
  (merged to 'next' on 2015-02-12 at 614331f)
 + Documentation: what does "git log --indexed-objects" even mean?

 "git log --help" used to show rev-list options that are irrelevant
 to the "log" command.


* jc/t4122-use-test-write-lines (2015-01-28) 1 commit
  (merged to 'next' on 2015-02-12 at 3ceaae3)
 + t4122: use test_write_lines from test-lib-functions


* jk/dumb-http-idx-fetch-fix (2015-01-27) 1 commit
  (merged to 'next' on 2015-02-12 at 6338345)
 + dumb-http: do not pass NULL path to parse_pack_index

 A broken pack .idx file in the receiving repository prevented the
 dumb http transport from fetching a good copy of it from the other
 side.


* jk/remote-curl-an-array-in-struct-cannot-be-null (2015-01-28) 1 commit
  (merged to 'next' on 2015-02-12 at 669040d)
 + do not check truth value of flex arrays

 Fix a misspelled conditional that is always true.


* jk/status-read-branch-name-fix (2015-01-28) 1 commit
  (merged to 'next' on 2015-02-12 at 1af96a9)
 + read_and_strip_branch: fix typo'd address-of operator

 Code to read branch name from various files in .git/ directory
 would have misbehaved if the code to write them left an empty file.


* ks/rebase-i-abbrev (2015-01-22) 1 commit
  (merged to 'next' on 2015-02-12 at 35c3739)
 + rebase -i: use full object name internally throughout the script

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


* mg/commit-author-no-match-malformed-message (2015-01-26) 1 commit
  (merged to 'next' on 2015-02-12 at 200cd9c)
 + commit: reword --author error message

 The error message from "git commit", when a non-existing author
 name was given as value to the "--author=" parameter, has been
 reworded to avoid misunderstanding.


* mg/push-repo-option-doc (2015-01-28) 1 commit
  (merged to 'next' on 2015-02-12 at 021ec32)
 + git-push.txt: document the behavior of --repo

 The "git push" documentation made the "--repo=<there>" option
 easily misunderstood.


* mh/deref-symref-over-helper-transport (2015-01-21) 1 commit
  (merged to 'next' on 2015-02-12 at de36191)
 + 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.

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

* jc/push-cert (2015-02-12) 1 commit
  (merged to 'next' on 2015-02-16 at f40b3c5)
 + transport-helper: fix typo in error message when --signed is not supported

 "git push --signed" gave an incorrectly worded error message when
 the other side did not support the capability.

 Will merge to 'master'.


* dp/remove-duplicated-header-inclusion (2015-02-13) 1 commit
 - do not include the same header twice

 Code clean-up.

 Will merge to 'next'.


* jc/diff-test-updates (2015-02-15) 6 commits
 - t4008: modernise style
 - t/diff-lib: check exact object names in compare_diff_raw
 - tests: do not borrow from COPYING and README from the real source
 - t4010: correct expected object names
 - t9300: correct expected object names
 - t4008: correct stale comments
 (this branch is used by jc/diff-b-m.)

 Test clean-up.

 Will merge to 'next'.


* jc/send-email-sensible-encoding (2015-02-13) 1 commit
 - send-email: ask confirmation if given encoding name is very short

 "git send-email" used to accept a mistaken "y" (or "yes") as an
 answer to "What encoding do you want to use [UTF-8]? " without
 questioning.  Now it asks for confirmation when the answer looks
 too short to be a valid encoding name.

 Will merge to 'next'.


* jk/push-config (2015-02-17) 4 commits
 - [NEEDSACK] push: allow --follow-tags to be set by config push.followTags
 - cmd_push: pass "flags" pointer to config callback
 - cmd_push: set "atomic" bit directly
 - git_push_config: drop cargo-culted wt_status pointer

 Waiting for Ack and/or update for the tip one from Dave Olszewski
 ($gmane/263880, $gmane/263991).


* km/send-email-getopt-long-workarounds (2015-02-16) 1 commit
 - git-send-email.perl: support no- prefix with older GetOptions

 Even though we officially haven't dropped Perl 5.8 support, the
 Getopt::Long package that came with it does not support "--no-"
 prefix to negate a boolean option; manually add support to help
 people with older Getopt::Long package.

 Will merge to 'next'.


* mh/transport-capabilities (2015-02-13) 2 commits
 - transport-helper: ask the helper to set the same options for import as for fetch
 - transport-helper: ask the helper to set progress and verbosity options after asking for its capabilities

 Will merge to 'next'.


* sb/hex-object-name-is-at-most-41-bytes-long (2015-02-13) 1 commit
 - hex.c: reduce memory footprint of sha1_to_hex static buffers

 Will merge to 'next'.


* jk/daemon-interpolate (2015-02-17) 3 commits
 - daemon: sanitize incoming virtual hostname
 - t5570: test git-daemon's --interpolated-path option
 - git_connect: let user override virtual-host we send to daemon

 The "interpolated-path" option of "git daemon" inserted any string
 client declared on the "host=" capability request without checking.
 Sanitize and limit %H and %CH to a saner and a valid DNS name.

 Will merge to 'next'.


* rs/daemon-interpolate (2015-02-17) 2 commits
 - daemon: use callback to build interpolated path
 - daemon: look up client-supplied hostname lazily

 "git daemon" looked up the hostname even when "%CH" and "%IP"
 interpolations are not requested, which was unnecessary.

 Will merge to 'next'.


* sb/plug-leak-in-make-cache-entry (2015-02-17) 1 commit
 - read-cache.c: free cache entry when refreshing fails

 "update-index --refresh" used to leak when an entry cannot be
 refreshed for whatever reason.

 Will merge to 'next'.

 - git-status.txt: advertisement for untracked cache
 - untracked cache: guard and disable on system changes

 - untracked cache: invalidate dirs recursively if .gitignore changes
 - untracked cache: initial untracked cache validation
 - untracked cache: record .gitignore information and dir hierarchy

 Need extra sets of eyes to review this.


* tb/connect-ipv6-parse-fix (2015-01-22) 3 commits
 - t5500: show user name and host in diag-url
 - t5601: add more test cases for IPV6
 - connect.c: improve parsing of literal IPV6 addresses

 Need extra sets of eyes to review this.

 Will discard.


* bp/diff-relative-config (2015-01-07) 2 commits
 - diff: teach diff.relative to give default to --relative=<value>
 - diff: teach --no-relative to override earlier --relative

 No comments?  No interests?


* jc/diff-b-m (2015-02-17) 4 commits
 . WIP: diff-b-m
 - diffcore-rename: allow easier debugging
 - diffcore-rename.c: add locate_rename_src()
 - diffcore-break: allow debugging
 (this branch uses jc/diff-test-updates.)

 "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.


* nd/slim-index-pack-memory-usage (2015-02-10) 3 commits
 - index-pack: kill union delta_base to save memory
 - FIXUP
 - index-pack: reduce memory footprint a bit

 Experimental?


* 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

 - 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.

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

 Will merge to 'next'.


* jk/sanity (2015-02-15) 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

 The tests that wanted to see that file becomes unreadable after
 running "chmod a-r file", and the tests that wanted to make sure it
 is not run as root, we used "can we write into the / directory?" as
 a cheap substitute, but on some platforms that is not a good
 heuristics.  The tests and their prerequisites have been updated to
 check what they really require.

 Will merge to 'next'.


* ab/merge-file-prefix (2015-02-11) 1 commit
  (merged to 'next' on 2015-02-16 at 89e0252)
 + merge-file: correctly open files when in a subdir

 "git merge-file" did not work correctly in a subdirectory.

 Will merge to 'master'.

 "git blame" died, trying to free an uninitialized piece of memory.

 Will merge to 'master'.


* es/squelch-openssl-warnings-on-macosx (2015-02-09) 1 commit
  (merged to 'next' on 2015-02-16 at bbe2880)
 + git-compat-util: do not step on MAC_OS_X_VERSION_MIN_REQUIRED

 An earlier workaround to squelch unhelpful deprecation warnings
 from the complier on Mac OSX unnecessarily set minimum required
 version of the OS, which the user might want to raise (or lower)
 for other reasons.

 Will merge to 'master'.


* jc/max-io-size-and-ssize-max (2015-02-12) 1 commit
 - xread/xwrite: clip MAX_IO_SIZE to SSIZE_MAX

 Our default I/O size (8 MiB) for large files was too large for some
 platforms with smaller SSIZE_MAX, leading to read(2)/write(2)
 failures.

 Will merge to 'next'.


* jk/fast-import-die-nicely-fix (2015-02-10) 1 commit
 - fast-import: avoid running end_packfile recursively

 "git fast-import" used to crash when it could not close and
 conclude the resulting packfile cleanly.

 Will merge to 'next'.

 Under discussion ($gmane/263552)


* mh/refs-have-new (2015-02-17) 13 commits
 - refs.h: remove duplication in function docstrings
 - update_ref(): improve documentation
 - ref_transaction_verify(): new function to check a reference's value
 - ref_transaction_delete(): check that old_sha1 is not null_sha1
 - ref_transaction_create(): check that new_sha1 is valid
 - commit: avoid race when creating orphan commits
 - commit: add tests of commit races
 - ref_transaction_delete(): remove "have_old" parameter
 - ref_transaction_update(): remove "have_old" parameter
 - struct ref_update: move "have_old" into "flags"
 - refs.c: change some "flags" to "unsigned int"
 - refs: remove the gap in the REF_* constant values
 - refs: move REF_DELETING to refs.c

 Simplify the ref transaction API around how "the ref should be
 pointing at this object" is specified.

 Looked sensible.
 Will merge to 'next', unless there is an objection.

  (merged to 'next' on 2015-02-16 at d7867a3)

  (merged to 'next' on 2015-02-16 at b7fc890)
 + config_buf_ungetc: warn when pushing back a random character
 + config: do not ungetc EOF

 Reading configuration from a blob object, when it ends with a lone
 CR, use to confuse the configuration parser.

 Will merge to 'master'.


* jk/decimal-width-for-uintmax (2015-02-05) 1 commit
  (merged to 'next' on 2015-02-16 at e608239)
 + decimal_width: avoid integer overflow

 We didn't format an integer that wouldn't fit in "int" but in
 "uintmax_t" correctly.

 Will merge to 'master'.


* ss/check-builtins-on-windows (2015-02-05) 1 commit
  (merged to 'next' on 2015-02-16 at 2c10cc1)

  (merged to 'next' on 2015-02-16 at e2daf10)
 + t/lib-gpg: sanity-check that we can actually sign
 + t/lib-gpg: include separate public keys in keyring.gpg

 Older GnuPG implementations may not correctly import the keyring
 material we prepare for the tests to use.

 Will merge to 'master'.


* jc/apply-beyond-symlink (2015-02-10) 4 commits
 - apply: do not touch a file beyond a symbolic link
 - apply: do not read from beyond a symbolic link
 - apply: do not read from the filesystem under --index
 - apply: reject input that touches outside the working area

 "git apply" was not very careful about reading from, removing,
 updating and creating paths outside the working tree (under
 --index/--cached) or the current directory (when used as a
 replacement for GNU patch).

 Will merge to 'next'.


* jc/remote-set-url-doc (2015-01-29) 1 commit
  (merged to 'next' on 2015-02-16 at 1f9c342)
 + Documentation/git-remote.txt: stress that set-url is not for triangular

 Clarify in the documentation that "remote.<nick>.pushURL" and
 "remote.<nick>.URL" are there to name the same repository accessed
 via different transports, not two separate repositories.

 Will merge to 'master'.

  (merged to 'next' on 2015-02-16 at 2e30424)

 Will merge to 'master'.


* jk/prune-mtime (2015-02-09) 2 commits
  (merged to 'next' on 2015-02-16 at 3d46eae)
 + sha1_file: fix iterating loose alternate objects
 + for_each_loose_file_in_objdir: take an optional strbuf path

 In v2.2.0, we broke "git prune" that runs in a repository that
 borrows from an alternate object store.

 Will merge to 'master'.


* ps/submodule-sanitize-path-upon-add (2015-02-02) 1 commit
  (merged to 'next' on 2015-02-16 at 8253132)

  (merged to 'next' on 2015-02-16 at de90f95)

 Certain older vintages of cURL give irregular output from
 "curl-config --vernum", which confused our build system.

 Will merge to 'master'.


* tc/missing-http-proxyauth (2015-02-03) 1 commit
 - http: support curl < 7.10.7

 We did not check the curl library version before using
 CURLOPT_PROXYAUTH feature that may not exist.

 Will merge to 'next'.

 - apply: detect and mark whitespace errors in context lines when fixing

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

 "fsck.warnings = <list of error tokens>" I suggested turned out to
 be an unpopular choice (sorry Dscho).

 Expecting a reroll.


* jk/strbuf-doc-to-header (2015-01-16) 7 commits
 - strbuf.h: group documentation for trim functions
 - strbuf.h: drop boilerplate descriptions of strbuf_split_*
 - strbuf.h: reorganize api function grouping headers
 - strbuf.h: format asciidoc code blocks as 4-space indent
 - strbuf.h: drop asciidoc list formatting from API docs

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

 Will merge to 'next'.


* nd/attr-optim (2014-12-29) 3 commits
 - 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
 - attr.c: rename arg name attr_nr to avoid shadowing the global one

 Optimize attribute look-up, mostly useful in "git grep" on a
 project that does not use many attributes, by avoiding it when we
 (should) know that the attributes are not defined in the first
 place.

 Will merge to 'next'.

* tc/t9001-noxmailer (2015-01-30) 1 commit
 . t9001: use older Getopt::Long boolean prefix '--no' rather than '--no-'

 Kyle's update to explicitly support --no-option with older
 Getopt::Long ($gmane/263203) makes this unnecessary.
