What's cooking in git.git (Apr 2016, #07; Mon, 25)

What's cooking in git.git (Apr 2016, #07; Mon, 25)

[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 ones marked with '.' do not appear in any of
the integration branches, but I am still holding onto them.

The 'master' branch now has the seventh batch of topics of this
cycle.

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"]

* ad/commit-have-m-option (2016-04-07) 2 commits
  (merged to 'next' on 2016-04-13 at 74088c2)
 + commit: do not ignore an empty message given by -m ''
 + commit: --amend -m '' silently fails to wipe message

 "git commit" misbehaved in a few minor ways when an empty message
 is given via -m '', all of which has been corrected.


* ad/cygwin-wants-rename (2015-08-07) 1 commit
  (merged to 'next' on 2016-04-19 at 1352ede)
 + config.mak.uname: Cygwin needs OBJECT_CREATION_USES_RENAMES

 On Cygwin, object creation uses the "create a temporary and then
 rename it to the final name" pattern, not "create a temporary,
 hardlink it to the final name and then unlink the temporary"
 pattern.

 This is necessary to use Git on Windows shared directories, and is
 already enabled for the MinGW and plain Windows builds.  It also
 has been used in Cygwin packaged versions of Git for quite a while.
 See http://thread.gmane.org/gmane.comp.version-control.git/291853
 ($gmane/275680, $gmane/291853).


* dt/pre-refs-backend (2016-04-10) 24 commits
  (merged to 'next' on 2016-04-13 at 0a8f9dd)
 + refs: on symref reflog expire, lock symref not referrent

 refs backends.


* en/merge-octopus-fix (2016-04-12) 2 commits
  (merged to 'next' on 2016-04-13 at 600b479)
 + merge-octopus: abort if index does not match HEAD
 + t6044: new merge testcases for when index doesn't match HEAD

 "merge-octopus" strategy did not ensure that the index is clean
 when merge begins.


* en/merge-trivial-fix (2016-04-12) 2 commits
  (merged to 'next' on 2016-04-13 at fb3ea86)
 + builtin/merge.c: fix a bug with trivial merges
 + t7605: add a testcase demonstrating a bug with trivial merges

 When "git merge" notices that the merge can be resolved purely at
 the tree level (without having to merge blobs) and the resulting
 tree happens to already exist in the object store, it forgot to
 update the index, which lead to an inconsistent state for later
 operations.


* ew/send-email-drop-data-dumper (2016-04-06) 1 commit
  (merged to 'next' on 2016-04-13 at 180266c)
 + send-email: do not load Data::Dumper

 Code clean-up.


* ew/send-email-readable-message-id (2016-04-06) 1 commit
  (merged to 'next' on 2016-04-13 at 422959a)
 + send-email: more meaningful Message-ID

 "git send-email" now uses a more readable timestamps when
 formulating a message ID.


* jc/http-socks5h (2016-04-10) 1 commit
  (merged to 'next' on 2016-04-13 at eb27afc)
 + http: differentiate socks5:// and socks5h://

 The socks5:// proxy support added back in 2.6.4 days was not aware
 that socks5h:// proxies behave differently.


* jc/rerere-multi (2016-04-06) 11 commits
  (merged to 'next' on 2016-04-13 at 3db2753)
 + rerere: adjust 'forget' to multi-variant world order
 + rerere: split code to call ll_merge() further
 + rerere: move code related to "forget" together
 + rerere: gc and clear
 + 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/xstrfmt-null-with-prec-0 (2016-04-07) 1 commit
  (merged to 'next' on 2016-04-13 at 2457462)
 + setup.c: do not feed NULL to "%.*s" even with precision 0

 Code cleanup.


* jk/do-not-printf-NULL (2016-04-10) 3 commits
  (merged to 'next' on 2016-04-13 at 60912e3)
 + git_config_set_multivar_in_file: handle "unset" errors
 + git_config_set_multivar_in_file: all non-zero returns are errors
 + config: lower-case first word of error strings

 "git config" had a codepath that tried to pass a NULL to
 printf("%s"), which nobody seems to have noticed.


* jk/use-write-script-more (2016-04-12) 3 commits
  (merged to 'next' on 2016-04-13 at d6718bf)
 + t3404: use write_script
 + t1020: do not overuse printf and use write_script
 + t5532: use write_script

 Code clean-up.


* ky/imap-send (2016-04-13) 2 commits
  (merged to 'next' on 2016-04-13 at 52cf493)
 + imap-send: fix CRAM-MD5 response calculation
 + imap-send: check for NOLOGIN capability only when using LOGIN command

 Support for CRAM-MD5 authentication method in "git imap-send" did
 not work well.


* ky/imap-send-openssl-1.1.0 (2016-04-08) 4 commits
  (merged to 'next' on 2016-04-13 at 49d2643)
 + configure: remove checking for HMAC_CTX_cleanup
 + imap-send: avoid deprecated TLSv1_method()
 + imap-send: check NULL return of SSL_CTX_new()
 + imap-send: use HMAC() function provided by OpenSSL

 Upcoming OpenSSL 1.1.0 will break compilation b updating a few APIs
 we use in imap-send, which has been adjusted for the change.


* sb/submodule-helper-clone-regression-fix (2016-04-01) 6 commits
  (merged to 'next' on 2016-04-13 at c6584bb)
 + submodule--helper, module_clone: catch fprintf failure
 + submodule--helper: do not borrow absolute_path() result for too long
 + submodule--helper, module_clone: always operate on absolute paths
 + submodule--helper clone: create the submodule path just once
 + submodule--helper: fix potential NULL-dereference
 + recursive submodules: test for relative paths
 (this branch is used by sb/submodule-init.)

 A partial rewrite of "git submodule" in the 2.7 timeframe changed
 the way the gitdir: pointer in the submodules point at the real
 repository location to use absolute paths by accident.  This has
 been corrected.


* sb/submodule-path-misc-bugs (2016-03-30) 6 commits
  (merged to 'next' on 2016-04-18 at 9daa5ce)
 + t7407: make expectation as clear as possible
 + submodule update: test recursive path reporting from subdirectory
 + submodule update: align reporting path for custom command execution
 + submodule status: correct path handling in recursive submodules
 + submodule update --init: correct path handling in recursive submodules
 + submodule foreach: correct path display in recursive submodules
 (this branch is used by sb/submodule-init.)

 "git submodule" reports the paths of submodules the command
 recurses into, but this was incorrect when the command was not run
 from the root level of the superproject.

[New Topics]

* js/name-rev-use-oldest-ref (2016-04-22) 1 commit
 - name-rev: include taggerdate in considering the best name

 "git describe --contains" often made a hard-to-justify choice of
 tag to give name to a given commit, because it tried to come up
 with a name with smallest number of hops from a tag, causing an old
 commit whose close descendant that is recently tagged were not
 described with respect to an old tag but with a newer tag.  It did
 not help that its computation of "hop" count was further tweaked to
 penalize being on a side branch of a merge.  The logic has been
 updated to favor using the tag with the oldest tagger date, which
 is a lot easier to explain to the end users: "We describe a commit
 in terms of the (chronologically) oldest tag that contains the
 commit."

 Will merge to 'next'.


* js/win32-mmap (2016-04-22) 3 commits
  (merged to 'next' on 2016-04-22 at cd39c60)
 + mmap(win32): avoid expensive fstat() call
 + mmap(win32): avoid copy-on-write when it is unnecessary
 + win32mmap: set errno appropriately

 mmap emulation on Windows has been optimized.

 Will merge to 'master'.


* nd/remove-unused (2016-04-22) 2 commits
 - wrapper.c: delete dead function git_mkstemps()
 - dir.c: remove dead function fnmatch_icase()

 Code cleanup.

 Will merge to 'next'.

 Code cleanup.

 Will merge to 'next'.


* sg/test-lib-simplify-expr-away (2016-04-22) 1 commit
 - test-lib: simplify '--option=value' parsing

 Code cleanup.

 Will merge to 'next'.


* ew/fast-import-unpack-limit (2016-04-24) 1 commit
 - fast-import: implement unpack limit

 "git fast-import" learned the same performance trick to avoid
 creating too small a packfile as "git fetch" and "git push" have,
 using *.unpackLimit configuration.

 Need to pick up the rerolled version.
 ($gmane/292562)


* jd/send-email-to-whom (2016-04-25) 1 commit
 - send-email: fix grammo in the prompt that asks e-mail recipients

 A question by "git send-email" to ask the identity of the sender
 has been updated.

 Will merge to 'next'.


* ld/p4-test-py3 (2016-04-25) 2 commits
 - git-p4 tests: work with python3 as well as python2
 - git-p4 tests: cd to testdir before running python

 The test scripts for "git p4" (but not "git p4" implementation
 itself) has been updated so that they would work even on a system
 where the installed version of Python is python 3.


* ls/p4-lfs-test-fix-2.7.0 (2016-04-24) 1 commit
 - t9824: fix broken &&-chain in a subshell

 Fix a broken test.

 Will merge to 'next'.

[Stalled]

* ar/diff-args-osx-precompose (2016-04-05) 1 commit
 - diff: run arguments through precompose_argv

 Many commands normalize command line arguments from NFD to NFC
 variant of UTF-8 on OSX, but commands in the "diff" family did
 not, causing "git diff $path" to complain that no such path is
 known to Git.  They have been taught to do the normalization.

 Will be rerolled?
 ($gmane/290724)


* nd/shallow-deepen (2016-04-13) 26 commits
 - fetch, upload-pack: --deepen=N extends shallow boundary by N commits
 - upload-pack: add get_reachable_list()
 - upload-pack: split check_unreachable() in two, prep for get_reachable_list()
 - t5500, t5539: tests for shallow depth excluding a ref
 - clone: define shallow clone boundary with --shallow-exclude
 - fetch: define shallow boundary with --shallow-exclude
 - upload-pack: support define shallow boundary by excluding revisions
 - refs: add expand_ref()
 - t5500, t5539: tests for shallow depth since a specific date
 - clone: define shallow clone boundary based on time with --shallow-since
 - fetch: define shallow boundary with --shallow-since
 - upload-pack: add deepen-since to cut shallow repos based on time
 - shallow.c: implement a generic shallow boundary finder based on rev-list
 - fetch-pack: use a separate flag for fetch in deepening mode
 - fetch-pack.c: mark strings for translating
 - fetch-pack: use a common function for verbose printing
 - fetch-pack: use skip_prefix() instead of starts_with()
 - upload-pack: move rev-list code out of check_non_tip()
 - upload-pack: tighten number parsing at "deepen" lines
 - upload-pack: use skip_prefix() instead of starts_with()
 - upload-pack: move "unshallow" sending code out of deepen()
 - upload-pack: remove unused variable "backup"
 - upload-pack: move "shallow" sending code out of deepen()
 - upload-pack: move shallow deepen code out of receive_needs()
 - transport-helper.c: refactor set_helper_option()
 - remote-curl.c: convert fetch_git() to use argv_array

 The existing "git fetch --depth=<n>" option was hard to use
 correctly when making the history of an existing shallow clone
 deeper.  A new option, "--deepen=<n>", has been added to make this
 easier to use.  "git clone" also learned "--shallow-since=<date>"
 and "--shallow-exclude=<tag>" options to make it easier to specify
 "I am interested only in the recent N months worth of history" and
 "Give me only the history since that version".

 Needs review.

 - completion: cache the path to the repository
 - completion: extract repository discovery from __gitdir()

 - completion tests: add tests for the __git_refs() helper function
 - completion tests: check __gitdir()'s output in the error cases
 - completion tests: consolidate getting path of current working directory
 - completion tests: make the $cur variable local to the test helper functions
 - completion tests: don't add test cruft to the test repository
 - completion: improve __git_refs()'s in-code documentation

 Will be rerolled.

* az/p4-bare-no-rebase (2016-02-19) 1 commit
 - git-p4.py: Don't try to rebase on submit from bare repository

 "git p4 submit" attempts to do a rebase, which would fail if done
 in a bare repository.  Not doing this rebase would paper over the
 failure, which is what this patch does, but it is unclear what the
 side effect of not rebasing is.

 Needs a better explanation.


* ss/commit-dry-run-resolve-merge-to-no-op (2016-02-17) 1 commit
 - wt-status.c: set commitable bit if there is a meaningful merge.

 "git commit --dry-run" reported "No, no, you cannot commit." in one
 case where "git commit" would have allowed you to commit, and this
 improves it a little bit ("git commit --dry-run --short" still does
 not give you the correct answer, for example).


* nd/icase (2016-02-15) 12 commits
 - grep.c: reuse "icase" variable
 - diffcore-pickaxe: support case insensitive match on non-ascii
 - diffcore-pickaxe: "share" regex error handling code
 - grep/pcre: support utf-8
 - gettext: add is_utf8_locale()
 - grep/pcre: prepare locale-dependent tables for icase matching
 - grep/icase: avoid kwsset when -F is specified
 - grep/icase: avoid kwsset on literal non-ascii strings
 - test-regex: expose full regcomp() to the command line
 - test-regex: isolate the bug test code
 - grep: break down an "if" stmt in preparation for next changes
 - grep: allow -F -i combination

 "git grep -i" has been taught to fold case in non-ascii locales.

 Needs review.

* ec/annotate-deleted (2015-11-20) 1 commit
 - annotate: skip checking working tree if a revision is provided

 Usability fix for annotate-specific "<file> <rev>" syntax with deleted
 files.

 Waiting for review.


* dg/subtree-rebase-test (2016-01-19) 1 commit
 - contrib/subtree: Add a test for subtree rebase that loses commits

 Reviewed up to v5.
 Will be rerolled.
 ($gmane/284426)


* js/am-3-merge-recursive-direct (2015-10-12) 2 commits
 - 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, the change needs to be 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 be rerolled.

* dk/gc-more-wo-pack (2016-01-13) 4 commits
 - gc: clean garbage .bitmap files from pack dir

 - t5304: test .bitmap garbage files
 - prepare_packed_git(): find more garbage

 Follow-on to dk/gc-idx-wo-pack topic, to clean up stale
 .bitmap and .keep files.

 Waiting for a reroll.
 ($gmane/284368).


* 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.
 Will discard.

[Cooking]

* sb/clone-shallow-passthru (2016-04-25) 1 commit
 - clone: add `--shallow-submodules` flag

 "git clone" learned "--shallow-submodules" option.

 Modulo minor nits, looked ready.
 ($gmane/292539)


* da/user-useconfigonly (2016-04-01) 2 commits
  (merged to 'next' on 2016-04-22 at 26845a5)
 + ident: give "please tell me" message upon useConfigOnly error
 + ident: check for useConfigOnly before auto-detection of name/email

 The "user.useConfigOnly" configuration variable makes it an error
 if users do not explicitly set user.name and user.email.  However,
 its check was not done early enough and allowed another error to
 trigger, reporting that the default value we guessed from the
 system setting was unusable.  This was a suboptimal end-user
 experience as we want the users to set user.name/user.email without
 relying on the auto-detection at all.

 Will merge to 'master'.


* jd/p4-jobs-in-commit (2016-04-19) 2 commits
 - git-p4: add P4 jobs to git commit message
 - git-p4: clean-up code style in tests

 "git p4" learned to record P4 jobs in Git commit that imports from
 the history in Perforce.

  (merged to 'next' on 2016-04-22 at 8df6d30)

 "git replace -e" did not honour "core.editor" configuration.

 Will merge to 'master'.


* ls/p4-lfs (2016-04-19) 2 commits
 - git-p4: fix Git LFS pointer parsing
 - travis-ci: update Git-LFS and P4 to the latest version

 Recent update to Git LFS broke "git p4" by changing the output from
 its "lfs pointer" subcommand.

  (merged to 'next' on 2016-04-22 at 089e788)

 "git mv old new" did not adjust the path for a submodule that lives
 as a subdirectory inside old/ directory correctly.

 Will merge to 'master'.


* tb/convert-eol-autocrlf (2016-04-25) 10 commits
 - ce_compare_data() did not respect conversion
 - t6038; use crlf on all platforms
 - convert.c: more safer crlf handling with text attribute
 - convert: unify the "auto" handling of CRLF
 - convert.c: stream and early out
 - read-cache: factor out get_sha1_from_index() helper
 - convert.c: ident + core.autocrlf didn't work
 - t0027: test cases for combined attributes
 - convert: allow core.autocrlf=input and core.eol=crlf
 - t0027: make commit_chk_wrnNNO() reliable

 The combination of text=auto & eol=crlf (or eol=lf for that matter)
 is taught to be much more useful; it used to be "auto detection"
 was defeated as if setting eol declares that the file _is_ text,
 but now text=auto is still in effect for such a path and the code
 refrains from applying eol conversion if it found the path is not
 text.  Also setting core.autocrlf to 'input' and core.eol to 'crlf'
 used to be rejected, but because the code gives precedence to
 core.autcrlf, there is no need to, hence we no longer reject the
 combination.

 Modulo minor nits, looked almost ready.

 - send-email: detect and offer to skip backup files

 A careless invocation of "git send-email directory/" after editing
 0001-change.patch with an editor often ends up sending both
 0001-change.patch and its backup file, 0001-change.patch~, causing
 embarrassment and a minor confusion.  Detect such an input and
 offer to skip the backup files when sending the patches out.

 Needs review.

 warning message since v2.5.0.

 It has been reported that git-gui still uses the deprecated syntax,
 which needs to be fixed before this final step can proceed.

Please note that it is not purely an optimization. It is also a bug fix in
case of a pretty full disk: on Windows, mmap() is backed by the page file
if it is in copy-on-write mode, and that can fail when the free space on
the drive that has the page file drops below a certain threshold.

Thanks,

Thanks.  How does this look then?

     + win32mmap: set errno appropriately

     mmap emulation on Windows has been optimized and work better without
     consuming paging store when not needed.

     Will merge to 'master'.

Reducing paging file consumption still falls into optimization in my
dictionary, though ;-)

Perfect!

Well, I considered this a bug fix when I worked on it: the command should
not have failed, and with my fix, it didn't ;-)
