Subject: What's cooking in git.git (Sep 2018, #02; Tue, 11)
Date: Tue, 11 Sep 2018 15:20:19 -0700	[thread overview]
Message-ID: <xmqqsh2fn0bg.fsf@gitster-ct.c.googlers.com> (raw)

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.

Git 2.19 is out.  The tip of 'next' has not been rewound yet; it is
a rare occasion for topics that would want to restart from a clean
slate to do so, so please raise your hand if you think that a topic
that is in 'next' should be ejected and given a chance to restart.

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

[Stalled]

* sl/commit-dry-run-with-short-output-fix (2018-07-30) 4 commits
 . commit: fix exit code when doing a dry run
 . wt-status: teach wt_status_collect about merges in progress
 . wt-status: rename commitable to committable
 . t7501: add coverage for flags which imply dry runs

 "git commit --dry-run" gave a correct exit status even during a
 conflict resolution toward a merge, but it did not with the
 "--short" option, which has been corrected.

 Seems to break 7512, 3404 and 7060 in 'pu'.


* ma/wrapped-info (2018-05-28) 2 commits
 - usage: prefix all lines in `vreportf()`, not just the first
 - usage: extract `prefix_suffix_lines()` from `advise()`

 An attempt to help making multi-line messages fed to warning(),
 error(), and friends more easily translatable.

 Will discard and wait for a cleaned-up rewrite.
 cf. <20180529213957.GF7964@sigill.intra.peff.net>


* hn/bisect-first-parent (2018-04-21) 1 commit
 - bisect: create 'bisect_flags' parameter in find_bisection()
 (this branch is used by tb/bisect-first-parent.)

 Preliminary code update to allow passing more flags down the
 bisection codepath in the future.

 We do not add random code that does not have real users to our
 codebase, so let's have it wait until such a real code materializes
 before too long.


* pb/bisect-helper-2 (2018-07-23) 8 commits
 - t6030: make various test to pass GETTEXT_POISON tests
 - bisect--helper: `bisect_start` shell function partially in C
 - bisect--helper: `get_terms` & `bisect_terms` shell function in C
 - bisect--helper: `bisect_next_check` shell function in C
 - bisect--helper: `check_and_set_terms` shell function in C
 - wrapper: move is_empty_file() and rename it as is_empty_or_missing_file()
 - bisect--helper: `bisect_write` shell function in C
 - bisect--helper: `bisect_reset` shell function in C

 Expecting a reroll.
 cf. <0102015f5e5ee171-f30f4868-886f-47a1-a4e4-b4936afc545d-000000@eu-west-1.amazonses.com>

 I just rebased the topic to a newer base as it did not build
 standalone with the base I originally queued the topic on, but
 otherwise there is no update to address any of the review comments
 in the thread above---we are still waiting for a reroll.


* jk/drop-ancient-curl (2017-08-09) 5 commits
 - 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.

 Expecting a reroll.


* 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).

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

* ab/fetch-tags-noclobber (2018-08-31) 9 commits
 - fetch: stop clobbering existing tags without --force
 - fetch: document local ref updates with/without --force
 - push doc: correct lies about how push refspecs work
 - push doc: move mention of "tag <tag>" later in the prose
 - push doc: remove confusing mention of remote merger
 - fetch tests: add a test for clobbering tag behavior
 - push tests: use spaces in interpolated string
 - push tests: make use of unused $1 in test description
 - fetch: change "branch" to "reference" in --force -h output

 The rules used by "git push" and "git fetch" to determine if a ref
 can or cannot be updated were inconsistent; specifically, fetching
 to update existing tags were allowed even though tags are supposed
 to be unmoving anchoring points.  "git fetch" was taught to forbid
 updates to existing tags without the "--force" option.

 Will merge to and cook in 'next'.
 This is a backward incompatible change but in a good way; it may
 still need to be treated carefully.


* es/worktree-forced-ops-fix (2018-09-05) 10 commits
 - doc-diff: force worktree add
 - worktree: delete .git/worktrees if empty after 'remove'
 - worktree: teach 'remove' to override lock when --force given twice
 - worktree: teach 'move' to override lock when --force given twice
 - worktree: teach 'add' to respect --force for registered but missing path
 - worktree: disallow adding same path multiple times
 - worktree: prepare for more checks of whether path can become worktree
 - worktree: generalize delete_git_dir() to reduce code duplication
 - worktree: move delete_git_dir() earlier in file for upcoming new callers
 - worktree: don't die() in library function find_worktree()

 Fix a bug in which the same path could be registered under multiple
 worktree entries if the path was missing (for instance, was removed
 manually).  Also, as a convenience, expand the number of cases in
 which --force is applicable.

 Will merge to 'next'.


* jk/patch-corrupted-delta-fix (2018-08-30) 6 commits
 - t5303: use printf to generate delta bases
 - patch-delta: handle truncated copy parameters
 - patch-delta: consistently report corruption
 - patch-delta: fix oob read
 - t5303: test some corrupt deltas
 - test-delta: read input into a heap buffer

 Malformed or crafted data in packstream can make our code attempt
 to read or write past the allocated buffer and abort, instead of
 reporting an error, which has been fixed.

 Will merge to 'next'.


* jk/pack-objects-with-bitmap-fix (2018-09-04) 4 commits
 - pack-bitmap: drop "loaded" flag
 - traverse_bitmap_commit_list(): don't free result
 - t5310: test delta reuse with bitmaps
 - bitmap_has_sha1_in_uninteresting(): drop BUG check
 (this branch uses jk/pack-delta-reuse-with-bitmap.)

 Hotfix of the base topic.  It may not be a bad idea to squash these
 in when the next development cycle opens.


* js/rebase-i-autosquash-fix (2018-09-04) 2 commits
 - rebase -i: be careful to wrap up fixup/squash chains
 - rebase -i --autosquash: demonstrate a problem skipping the last squash

 "git rebase -i" did not clear the state files correctly when a run
 of "squash/fixup" is aborted and then the user manually amended the
 commit instead, which has been corrected.

 Will merge to 'next'.


* nd/bisect-show-list-fix (2018-09-04) 1 commit
 - bisect.c: make show_list() build again

 Debugging aid update.

 Will merge to and cook in 'next'.


* nd/optim-reading-index-v4 (2018-09-04) 1 commit
 - read-cache.c: optimize reading index format v4

 The v4 format of the index file uses prefix compression to store
 the pathnames to save file size.  The codepath to read such a file
 has been optimized.

 Will merge to and cook in 'next'.


* sg/doc-trace-appends (2018-09-04) 1 commit
 - Documentation/git.txt: clarify that GIT_TRACE=/path appends

 Docfix.

 Will merge to 'next'.


* ds/format-commit-graph-docs (2018-08-21) 2 commits
 - commit-graph.txt: improve formatting for asciidoc
 - Docs: Add commit-graph tech docs to Makefile

 Design docs for the commit-graph machinery is now made into HTML as
 well as text.


* jk/diff-rendered-docs (2018-08-31) 5 commits
 - doc/Makefile: drop doc-diff worktree and temporary files on "make clean"
 - doc-diff: add --clean mode to remove temporary working gunk
 - doc-diff: fix non-portable 'man' invocation
 - doc-diff: always use oids inside worktree
  (merged to 'next' on 2018-08-22 at dd7a2b71cd)
 + SubmittingPatches: mention doc-diff

 Dev doc update.

 Will merge to 'next'.


* jk/pack-delta-reuse-with-bitmap (2018-08-21) 6 commits
  (merged to 'next' on 2018-08-22 at fc50b59dab)
 + pack-objects: reuse on-disk deltas for thin "have" objects
 + pack-bitmap: save "have" bitmap from walk
 + t/perf: add perf tests for fetches from a bitmapped server
 + t/perf: add infrastructure for measuring sizes
 + t/perf: factor out percent calculations
 + t/perf: factor boilerplate out of test_perf
 (this branch is used by jk/pack-objects-with-bitmap-fix.)

 When creating a thin pack, which allows objects to be made into a
 delta against another object that is not in the resulting pack but
 is known to be present on the receiving end, the code learned to
 take advantage of the reachability bitmap; this allows the server
 to send a delta against a base beyond the "boundary" commit.

 Will cook in 'next'.


* jk/rev-list-stdin-noop-is-ok (2018-08-22) 1 commit
  (merged to 'next' on 2018-08-27 at d5916f7bc1)
 + rev-list: make empty --stdin not an error

 "git rev-list --stdin </dev/null" used to be an error; it now shows
 no output without an error.  "git rev-list --stdin --default HEAD"
 still falls back to the given default when nothing is given on the
 standard input.

 Will cook in 'next'.


* js/rebase-in-c-5.5-work-with-rebase-i-in-c (2018-09-06) 2 commits
 - builtin rebase: prepare for builtin rebase -i
 - Merge branch 'ag/rebase-i-in-c' into js/rebase-in-c-5.5-work-with-rebase-i-in-c
 (this branch is used by pk/rebase-in-c-6-final; uses ag/rebase-i-in-c, pk/rebase-in-c, pk/rebase-in-c-2-basic, pk/rebase-in-c-3-acts, pk/rebase-in-c-4-opts and pk/rebase-in-c-5-test.)

 "rebase" that has been rewritten learns the new calling convention
 used by "rebase -i" that was rewritten in C, tying the loose end
 between two GSoC topics that stomped on each other's toes.


* jk/trailer-fixes (2018-08-23) 8 commits
  (merged to 'next' on 2018-08-27 at 93b671b8c6)
 + append_signoff: use size_t for string offsets
 + sequencer: ignore "---" divider when parsing trailers
 + pretty, ref-filter: format %(trailers) with no_divider option
 + interpret-trailers: allow suppressing "---" divider
 + interpret-trailers: tighten check for "---" patch boundary
 + trailer: pass process_trailer_opts to trailer_info_get()
 + trailer: use size_t for iterating trailer list
 + trailer: use size_t for string offsets

 "git interpret-trailers" and its underlying machinery had a buggy
 code that attempted to ignore patch text after commit log message,
 which triggered in various codepaths that will always get the log
 message alone and never get such an input.

 Will cook in 'next'.


* tg/rerere-doc-updates (2018-08-29) 2 commits
  (merged to 'next' on 2018-08-31 at ce4fef1a97)
 + rerere: add note about files with existing conflict markers
 + rerere: mention caveat about unmatched conflict markers
 (this branch uses tg/rerere.)

 Clarify a part of technical documentation for rerere.

 Will cook in 'next'.


* ds/commit-graph-tests (2018-08-29) 1 commit
 - commit-graph: define GIT_TEST_COMMIT_GRAPH

 We can now optionally run tests with commit-graph enabled.

 Will merge to 'next'.


* jk/cocci (2018-08-29) 9 commits
  (merged to 'next' on 2018-08-31 at 914b4f17ce)
 + show_dirstat: simplify same-content check
 + read-cache: use oideq() in ce_compare functions
 + convert hashmap comparison functions to oideq()
 + convert "hashcmp() != 0" to "!hasheq()"
 + convert "oidcmp() != 0" to "!oideq()"
 + convert "hashcmp() == 0" to hasheq()
 + convert "oidcmp() == 0" to oideq()
 + introduce hasheq() and oideq()
 + coccinelle: use <...> for function exclusion

 spatch transformation to replace boolean uses of !hashcmp() to
 newly introduced oideq() is added, and applied, to regain
 performance lost due to support of multiple hash algorithms.

 Will cook in 'next'.


* js/add-i-coalesce-after-editing-hunk (2018-08-28) 1 commit
 - add -p: coalesce hunks before testing applicability

 Applicability check after a patch is edited in a "git add -i/p"
 session has been improved.

 Will hold.
 cf. <e5b2900a-0558-d3bf-8ea1-d526b078bbc2@talktalk.net>


* rs/mailinfo-format-flowed (2018-08-29) 1 commit
  (merged to 'next' on 2018-08-31 at 9e8b92176c)
 + mailinfo: support format=flowed

 "git mailinfo" used in "git am" learned to make a best-effort
 recovery of a patch corrupted by MUA that sends text/plain with
 format=flawed option.

 Will cook in 'next'.


* sb/submodule-move-head-with-corruption (2018-08-28) 2 commits
 - submodule.c: warn about missing submodule git directories
 - t2013: add test for missing but active submodule

 cf. <20180905191849.GB120842@aiede.svl.corp.google.com>


* tg/conflict-marker-size (2018-08-29) 1 commit
  (merged to 'next' on 2018-08-31 at 12099161f0)
 + .gitattributes: add conflict-marker-size for relevant files

 Developer aid.

 Will cook in 'next'.


* ts/doc-build-manpage-xsl-quietly (2018-08-29) 1 commit
  (merged to 'next' on 2018-08-31 at 7527e0f8d3)
 + Documentation/Makefile: make manpage-base-url.xsl generation quieter

 Build tweak.

 Will cook in 'next'.


* bp/checkout-new-branch-optim (2018-08-16) 1 commit
  (merged to 'next' on 2018-08-27 at e69bfd115f)
 + checkout: optimize "git checkout -b <new_branch>"

 "git checkout -b newbranch [HEAD]" should not have to do as much as
 checking out a commit different from HEAD.  An attempt is made to
 optimize this special case.

 Will cook in 'next'.


* ao/submodule-wo-gitmodules-checked-out (2018-08-14) 7 commits
 - submodule: support reading .gitmodules even when it's not checked out
 - t7506: clean up .gitmodules properly before setting up new scenario
 - submodule: use the 'submodule--helper config' command
 - submodule--helper: add a new 'config' subcommand
 - t7411: be nicer to future tests and really clean things up
 - submodule: factor out a config_set_in_gitmodules_file_gently function
 - submodule: add a print_config_from_gitmodules() helper

 The submodule support has been updated to read from the blob at
 HEAD:.gitmodules when the .gitmodules file is missing from the
 working tree.

 Expecting a reroll.

 I find the design a bit iffy in that our usual "missing in the
 working tree?  let's use the latest blob" fallback is to take it
 from the index, not from the HEAD.


* bw/submodule-name-to-dir (2018-08-10) 2 commits
  (merged to 'next' on 2018-08-22 at c17f83be24)
 + submodule: munge paths to submodule git directories
 + submodule: create helper to build paths to submodule gitdirs

 In modern repository layout, the real body of a cloned submodule
 repository is held in .git/modules/ of the superproject, indexed by
 the submodule name.  URLencode the submodule name before computing
 the name of the directory to make sure they form a flat namespace.

 Expecting further work on the topic.

 + pack-objects: move tree_depth into 'struct packing_data'
 + t5320: tests for delta islands
 + repack: add delta-islands support
 + pack-objects: add delta-islands support
 + pack-objects: refactor code into compute_layer_order()
 + Add delta-islands.{c,h}

 Lift code from GitHub to restrict delta computation so that an
 object that exists in one fork is not made into a delta against
 another object that does not appear in the same forked repository.

 Will cook in 'next'.


* md/filter-trees (2018-09-04) 7 commits
 - list-objects-filter: implement filter tree:0
 - list-objects-filter: use BUG rather than die
 - revision: mark non-user-given objects instead
 - rev-list: handle missing tree objects properly
 - list-objects: always parse trees gently
 - list-objects: refactor to process_tree_contents
 - list-objects: store common func args in struct

 The "rev-list --filter" feature learned to exclude all trees via
 "tree:0" filter.

 Will merge to 'next'.


* ng/status-i-short-for-ignored (2018-08-09) 1 commit
 - status: -i shorthand for --ignored command line option

 "git status --ignored" gained a shorthand "git status -i".

 What's the list opinion on this one?  It is Meh to me, but
 obviously the author cared enough to write a patch, so...

 + clone: report duplicate entries on case-insensitive filesystems

 Running "git clone" against a project that contain two files with
 pathnames that differ only in cases on a case insensitive
 filesystem would result in one of the files lost because the
 underlying filesystem is incapable of holding both at the same
 time.  An attempt is made to detect such a case and warn.

  (merged to 'next' on 2018-08-27 at b1d841d034)
 + Document update for nd/unpack-trees-with-cache-tree
  (merged to 'next' on 2018-08-22 at 138b902673)
 + cache-tree: verify valid cache-tree in the test suite
 + unpack-trees: add missing cache invalidation
 + unpack-trees: reuse (still valid) cache-tree from src_index
 + unpack-trees: reduce malloc in cache-tree walk
 + unpack-trees: optimize walking same trees with cache-tree
 + unpack-trees: add performance tracing
 + trace.h: support nested performance tracing

 The unpack_trees() API used in checking out a branch and merging
 walks one or more trees along with the index.  When the cache-tree
 in the index tells us that we are walking a tree whose flattened
 contents is known (i.e. matches a span in the index), as linearly
 scanning a span in the index is much more efficient than having to
 open tree objects recursively and listing their entries, the walk
 can be optimized, which is done in this topic.

* pw/add-p-select (2018-07-26) 4 commits
 - add -p: optimize line selection for short hunks
 - add -p: allow line selection to be inverted
 - add -p: select modified lines correctly
 - add -p: select individual hunk lines

 "git add -p" interactive interface learned to let users choose
 individual added/removed lines to be used in the operation, instead
 of accepting or rejecting a whole hunk.

 Will hold.

* ds/commit-graph-with-grafts (2018-08-21) 8 commits
 - commit-graph: close_commit_graph before shallow walk
 - commit-graph: not compatible with uninitialized repo
 - commit-graph: not compatible with grafts
 - commit-graph: not compatible with replace objects
 - test-repository: properly init repo
 - commit-graph: update design document
 - refs.c: upgrade for_each_replace_ref to be a each_repo_ref_fn callback
 - refs.c: migrate internal ref iteration to pass thru repository argument

 The recently introduced commit-graph auxiliary data is incompatible
 with mechanisms such as replace & grafts that "breaks" immutable
 nature of the object reference relationship.  Disable optimizations
 based on its use (and updating existing commit-graph) when these
 incompatible features are in use in the repository.

 Replaced with a newer version.

* jn/gc-auto (2018-07-17) 3 commits
 - gc: do not return error for prior errors in daemonized mode
 - gc: exit with status 128 on failure
 - gc: improve handling of errors reading gc.log

 "gc --auto" ended up calling exit(-1) upon error, which has been
 corrected to use exit(1).  Also the error reporting behaviour when
 daemonized has been updated to exit with zero status when stopping
 due to a previously discovered error (which implies there is no
 point running gc to improve the situation); we used to exit with
 failure in such a case.

 What's the donness of this one?

* lt/date-human (2018-07-09) 1 commit
 - Add 'human' date format

 A new date format "--date=human" that morphs its output depending

 Ejected; seems to break existing repositories that use partialclone
 repository extension.

 I haven't seen much interest in this topic on list.  What's the
 doneness of this thing?

 I do not particularly mind adding code to support a niche feature
 as long as it is cleanly made and it is clear that the feature
 won't negatively affect those who do not use it, so a review from
 that point of view may also be appropriate.
