- Subject: What's cooking in git.git (Oct 2017, #02; Wed, 11)
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 ones marked with '.' do not appear in any of
the integration branches, but I am still holding onto them.
2.15-rc1 has been tagged. Some of the topic marked "Will merge to
'master'" below might still become part of 2.15 final, while others
may be left to be merged after the final, to become part of the
release after that one (2.16?).
You can find the changes described here in the integration branches
of the repositories listed at
[Graduated to "master"]
* ar/request-pull-phrasofix (2017-10-03) 1 commit
(merged to 'next' on 2017-10-03 at 07807bba90)
+ request-pull: capitalise "Git" to make it a proper noun
Spell the name of our system as "Git" in the output from
* ds/avoid-overflow-in-midpoint-computation (2017-10-10) 1 commit
(merged to 'next' on 2017-10-10 at 6279867a5d)
+ cleanup: fix possible overflow errors in binary search
* er/fast-import-dump-refs-on-checkpoint (2017-09-29) 1 commit
(merged to 'next' on 2017-10-03 at 4e7b0e7ec1)
+ fast-import: checkpoint: dump branches/tags/marks even if object_count==0
The checkpoint command "git fast-import" did not flush updates to
refs and marks unless at least one object was created since the
last checkpoint, which has been corrected, as these things can
happen without any new object getting created.
* hn/string-list-doc (2017-10-06) 1 commit
(merged to 'next' on 2017-10-10 at d214a7c369)
+ api-argv-array.txt: remove broken link to string-list API
* jk/refs-df-conflict (2017-10-07) 2 commits
(merged to 'next' on 2017-10-10 at d5953a1ced)
+ refs_resolve_ref_unsafe: handle d/f conflicts for writes
+ t3308: create a real ref directory/file conflict
An ancient bug that made Git misbehave with creation/renaming of
refs has been fixed.
* jk/sha1-loose-object-info-fix (2017-10-06) 1 commit
(merged to 'next' on 2017-10-10 at bcfd9c4e3f)
+ sha1_loose_object_info: handle errors from unpack_sha1_rest
Leakfix and futureproofing.
* jk/ui-color-always-to-auto (2017-10-04) 3 commits
(merged to 'next' on 2017-10-05 at 792ae936cf)
+ Merge branch 'jk/ui-color-always-to-auto-maint' into jk/ui-color-always-to-auto
+ t7301: use test_terminal to check color
+ t4015: use --color with --color-moved
(this branch uses jk/ui-color-always-to-auto-maint.)
Fix regression of "git add -p" for users with "color.ui = always"
in their configuration, by merging the topic below and adjusting it
for the 'master' front.
* jk/ui-color-always-to-auto-maint (2017-10-04) 10 commits
+ color: make "always" the same as "auto" in config
+ provide --color option for all ref-filter users
+ t3205: use --color instead of color.branch=always
+ t3203: drop "always" color test
+ t6006: drop "always" color config tests
+ t7502: use diff.noprefix for --verbose test
+ t7508: use test_terminal for color output
+ t3701: use test-terminal to collect color output
+ t4015: prefer --color to -c color.diff=always
+ test-terminal: set TERM=vt100
(this branch is used by jk/ui-color-always-to-auto.)
Users with "color.ui = always" in their configuration were broken
by a recent change that made plumbing commands to pay attention to
them as the patch created internally by "git add -p" were colored
(heh) and made unusable. Fix this regression by redefining
'always' to mean the same thing as 'auto'.
* jn/strbuf-doc-re-reuse (2017-10-04) 1 commit
(merged to 'next' on 2017-10-04 at 5940d412d9)

* ma/builtin-unleak (2017-10-02) 1 commit
(merged to 'next' on 2017-10-05 at 380cb74320)
+ builtin/: add UNLEAKs
Many variables that points at a region of memory that will live
throughout the life of the program have been marked with UNLEAK
marker to help the leak checkers concentrate on real leaks..

* tb/delimit-pretty-trailers-args-with-comma (2017-10-02) 1 commit
(merged to 'next' on 2017-10-04 at de5446a01c)
+ pretty.c: delimit "%(trailers)" arguments with ","
(this branch is used by tb/show-trailers-in-ref-filter.)
The feature that allows --pretty='%(trailers)' to take modifiers
like "fold" and "only" used to separate these modifiers with a
comma, i.e. "%(trailers:fold:only)", but we changed our mind and
use a comma, i.e. "%(trailers:fold,only)". Fast track this change
before this new feature becomes part of any official release.
* tb/ref-filter-empty-modifier (2017-10-05) 1 commit
(merged to 'next' on 2017-10-05 at 62cb67688a)
+ ref-filter.c: pass empty-string as NULL to atom parsers
In the "--format=..." option of the "git for-each-ref" command (and
its friends, i.e. the listing mode of "git branch/tag"), "%(atom:)"
(e.g. "%(refname:)", "%(body:)" used to error out. Instead, treat
them as if the colon and an empty string that follows it were not
* tb/show-trailers-in-ref-filter (2017-10-02) 6 commits
(merged to 'next' on 2017-10-05 at c7a697f15d)
+ ref-filter.c: parse trailers arguments with %(contents) atom
+ ref-filter.c: use trailer_opts to format trailers
+ t6300: refactor %(trailers) tests
+ doc: use "`<literal>`"-style quoting for literal strings
+ doc: 'trailers' is the preferred way to format trailers
+ t4205: unfold across multiple lines
"git for-each-ref --format=..." learned a new format element,
%(trailers), to show only the commit log trailer part of the log
* tg/memfixes (2017-10-04) 3 commits
(merged to 'next' on 2017-10-04 at fb338a5531)
+ sub-process: use child_process.args instead of child_process.argv
+ http-push: fix construction of hex value from path
+ path.c: fix uninitialized memory access
Fixes for a handful memory access issues identified by valgrind.
* dm/run-command-ignored-hook-advise (2017-10-10) 1 commit
(merged to 'next' on 2017-10-10 at 0827814922)
+ run-command: add hint when a hook is ignored
A hook script that is set unexecutable is simply ignored. Git
notifies when such a file is ignored, unless the message is
squelched via advice.ignoredHook configuration.
Will cook in 'next'.
* hv/fetch-moved-submodules-on-demand (2017-10-08) 5 commits
- DONTMERGE: mark failing tests for now
- submodule: simplify decision tree whether to or not to fetch
- implement fetching of moved submodules
- change submodule push test to use proper repository setup

* js/for-each-ref-remote-name-and-ref (2017-10-11) 3 commits
- for-each-ref: test :remotename and :remoteref
- for-each-ref: let upstream/push optionally report the remote ref name
- for-each-ref: let upstream/push optionally report the remote name
The "--format=..." option "git for-each-ref" takes learned to show
the name of the 'remote' repository and the ref at the remote side
that is affected for 'upstream' and 'push' via "%(push:remotename)"
* pb/bisect-helper (2017-10-06) 6 commits

* jc/no-cmd-as-subroutine (2017-10-11) 2 commits
- merge-ours: do not use cmd_*() as a subroutine
- describe: do not use cmd_*() as a subroutine
Calling cmd_foo() as if it is a general purpose helper function is
a no-no. Correct two instances of such to set an example.
* jc/doc-checkout (2017-10-11) 1 commit
- checkout doc: clarify command line args for "checkout paths" mode
Will merge to 'next'.
* mk/use-size-t-in-zlib (2017-08-10) 1 commit
. zlib.c: use size_t for size
The wrapper to call into zlib followed our long tradition to use
"unsigned long" for sizes of regions in memory, which have been
updated to use "size_t".
Needs resurrecting by making sure the fix is good and still applies
(or adjusted to today's codebase).
* mg/status-in-progress-info (2017-05-10) 2 commits
- status --short --inprogress: spell it as --in-progress
- status: show in-progress info for short status
"git status" learns an option to report various operations
(e.g. "merging") that the user is in the middle of.
* nd/worktree-move (2017-04-20) 6 commits
- worktree remove: new command
- worktree move: refuse to move worktrees with submodules
- worktree move: accept destination as directory
- worktree move: new command

"git worktree" learned move and remove subcommands.
Expecting a reroll.
* sg/clone-refspec-from-command-line-config (2017-06-16) 2 commits
- Documentation/clone: document ignored configuration variables
- clone: respect additional configured fetch refspecs during initial fetch
(this branch is used by sg/remote-no-string-refspecs.)
"git clone -c var=val" is a way to set configuration variables in
the resulting repository, but it is more useful to also make these
variables take effect while the initial clone is happening,
e.g. these configuration variables could be fetch refspecs.
Waiting for a response.
* jc/merge-symlink-ours-theirs (2017-09-26) 1 commit
- merge: teach -Xours/-Xtheirs to symbolic link merge
"git merge -Xours/-Xtheirs" learned to use our/their version when
resolving a conflicting updates to a symbolic link.
* jt/partial-clone-lazy-fetch (2017-10-02) 18 commits
- fetch-pack: restore save_commit_buffer after use
- unpack-trees: batch fetching of missing blobs
- clone: configure blobmaxbytes in created repos
- clone: support excluding large blobs
- fetch: support excluding large blobs
- fetch: refactor calculation of remote list
- fetch-pack: support excluding large blobs
- pack-objects: support --blob-max-bytes
- pack-objects: rename want_.* to ignore_.*
- gc: do not repack promisor packfiles
- rev-list: support termination at promisor objects

- fsck: introduce partialclone extension
A journey for "git clone" and "git fetch" to become "lazier" by
depending more on its remote repository---this is the beginning of
* ma/lockfile-fixes (2017-10-07) 12 commits
- read_cache: roll back lock in `update_index_if_able()`
- read-cache: leave lock in right state in `write_locked_index()`
- read-cache: drop explicit `CLOSE_LOCK`-flag
- cache.h: document `write_locked_index()`
- apply: remove `newfd` from `struct apply_state`
- apply: move lockfile into `apply_state`
- cache-tree: simplify locking logic
- checkout-index: simplify locking logic
- tempfile: fix documentation on `delete_tempfile()`
- lockfile: fix documentation on `close_lock_file_gently()`
- treewide: prefer lockfiles on the stack
- sha1_file: do not leak `lock_file`
An earlier update made it possible to use an on-stack in-core
lockfile structure (as opposed to having to deliberately leak an
on-heap one). Many codepaths have been updated to take advantage
of this new facility.
Looking good. Is this ready for 'next'?
* ot/mru-on-list (2017-10-01) 1 commit
(merged to 'next' on 2017-10-07 at e6ad4a16a2)
+ mru: use double-linked list from list.h
The first step to getting rid of mru API and using the
doubly-linked list API directly instead.
Will cook in 'next'.
* jm/svn-pushmergeinfo-fix (2017-09-17) 1 commit
- git-svn: fix svn.pushmergeinfo handling of svn+ssh usernames.
"git svn dcommit" did not take into account the fact that a
svn+ssh:// URL with a username@ (typically used for pushing) refers
to the same SVN repository without the username@ and failed when
svn.pushmergeinfo option is set.
Needs a test, perhaps as a follow-up patch.
* mg/merge-base-fork-point (2017-09-17) 3 commits
- merge-base: find fork-point outside partial reflog
- merge-base: return fork-point outside reflog
- t6010: test actual test output
"merge-base --fork-point $branch $commit" is used to guess on which
commit among the commits that were once at the tip of the $branch the
$commit was built on top of, and it learns these historical tips from
the reflog of the $branch. When the true fork-point is lost due to
pruning of old reflog entries, the command does not give any output,
because it has no way to guess correctly and does not want to mislead
the user with a wrong guess.
The command has been updated to give the best but not known to be
correct guess, based on a hope that a merge-base between $commit and a
virtual merge across all the reflog entries that still are available
for $branch may still be a closer to the true fork-point than the
merge-base between $commit and the current tip of the $branch.
This may have to be offered by an additional option, to allow the
users that are prepared to see a potentially incorrect guess to opt
into the feature, without affecting the current callers that may not
be prepared to accept a guess that is not known to be correct.
What's the doneness of this one?
* ds/find-unique-abbrev-optim (2017-10-09) 4 commits
- sha1_name: minimize OID comparisons during disambiguation
- sha1_name: parse less while finding common prefix
- sha1_name: unroll len loop in find_unique_abbrev_r()
- p4211-line-log.sh: add log --online --raw --parents perf test
Optimize the code to find shortest unique prefix of object names.

* mg/merge-pre-merge-hook (2017-09-24) 4 commits
- t7503: add tests for pre-merge-hook
- merge: --no-verify to bypass pre-merge hook
- merge: do no-verify like commit
- git-merge: honor pre-merge hook
"git merge" learned a 'pre-merge' hook, that would be triggered
before the merge commit is created by a clean auto-merge.
Waiting for review to conclude.
* bp/fsmonitor (2017-10-05) 15 commits
(merged to 'next' on 2017-10-05 at 964a029d13)
+ fsmonitor: preserve utf8 filenames in fsmonitor-watchman log
+ fsmonitor: read entirety of watchman output

+ update-index: add a new --force-write-index option
+ preload-index: add override to enable testing preload-index
+ bswap: add 64 bit endianness helper get_be64
We learned to talk to watchman to speed up "git status" and other
operations that need to see which paths have been modified.
Will cook in 'next'.
* bw/protocol-v1 (2017-10-04) 10 commits
- ssh: introduce a 'simple' ssh variant
- i5700: add interop test for protocol transition
- http: tell server that the client understands v1
- connect: tell server that the client understands v1
- connect: teach client to recognize v1 server response
- upload-pack, receive-pack: introduce protocol version 1
- daemon: recognize hidden request arguments
- protocol: introduce protocol extention mechanisms
- pkt-line: add packet_write function
- connect: in ref advertisement, shallows are last
A new mechanism to upgrade the wire protocol in place is proposed
and demonstrated that it works with the older versions of Git
without harming them.
Expecting a reroll.
The tip one needs to clarify that it is not just '-o' but also '-p'
option in the documentation. Other than that, the approach taken
by the series basically seems sane and well received.
* pc/submodule-helper (2017-10-07) 3 commits
- submodule: port submodule subcommand 'status' from shell to C
- submodule--helper: introduce for_each_listed_submodule()
- submodule--helper: introduce get_submodule_displaypath()
Is this ready for 'next'?
* bc/hash-algo (2017-10-04) 6 commits
- fixup! hash-algo: integrate hash algorithm support with repo setup
- hash-algo: switch empty tree and blob lookups to use hash abstraction
- hash-algo: integrate hash algorithm support with repo setup
- hash-algo: add structure representing hash algorithm
- setup: expose enumerated repo info
- Merge branch 'bc/vcs-svn-cleanup' into bc/hash-algo

- http: #error on too-old curl
- curl: remove ifdef'd code never used with curl >=7.19.4
- http: drop support for curl < 7.19.4
- http: drop support for curl < 7.16.0
- http: drop support for curl < 7.11.1
Some code in http.c that has bitrot is being removed.
Will be rerolled after tc/curl-with-backports stabilizes.
* sb/submodule-recursive-checkout-detach-head (2017-07-28) 2 commits
- Documentation/checkout: clarify submodule HEADs to be detached
- recursive submodules: detach HEAD from new state
"git checkout --recursive" may overwrite and rewind the history of
the branch that happens to be checked out in submodule
repositories, which might not be desirable. Detach the HEAD but
still allow the recursive checkout to succeed in such a case.
This needs justification in a larger picture; it is unclear why
this is better than rejecting recursive checkout, for example.
* jk/check-ref-format-oor-fix (2017-07-14) 1 commit
- check-ref-format: require a repository for --branch
Discussion slowly continues...

+ pathspec: die on empty strings as pathspec
+ t0027: do not use an empty string as a pathspec element
The final step to make an empty string as a pathspec element
illegal. We started this by first deprecating and warning a
pathspec that has such an element in 2.11 (Nov 2016).
Hopefully we can merge this down to the 'master' by the end of the
year? A deprecation warning period that is about 1 year does not
sound too bad.
Will cook in 'next'.
As the draft RelNotes says, let's merge this to 'master' after
this release cycle.

. colors: git_default_config() does not read color.ui
. Revert "color: check color.ui in git_default_config()"
Recent tip of 'master' and 'maint' (at least as of v2.14.2) has a
regression in "git add -p" for those who set ui.color=always in
their configuration, caused by us being overly aggressive in
allowing plumbing commands to honor the configuration to fix a
fallout from an earlier change that made everybody, even the
plumbing commands, to automatically color its output by default.
Revert it for now from the released version (and to be released
one) until we come up with a different fix to the problem.

. push: disable lazy --force-with-lease by default
Because "git push --force-with-lease[=<ref>]" that relies on the
stability of remote-tracking branches is unsafe when something
fetches into the repository behind user's back, it is now disabled
by default. A new configuration variable can be used to enable it
by users who know what they are doing. This would pave the way to
possibly turn `--force` into `--force-with-lease`.
Independent from disabling the feature by default, this stirred up
a discussion to replace the DWIM heuristics with a better one, which
deserves to be its own topic.
