Merge branch 'en/rename-directory-detection-reboot'

2018-05-23T05:38:19Z

Rename detection logic in "diff" family that is used in "merge" has learned to guess when all of x/a, x/b and x/c have moved to z/a, z/b and z/c, it is likely that x/d added in the meantime would also want to move to z/d by taking the hint that the entire directory 'x' moved to 'z'. A bug causing dirty files involved in a rename to be overwritten during merge has also been fixed as part of this work. Incidentally, this also avoids updating a file in the working tree after a (non-trivial) merge whose result matches what our side originally had. * en/rename-directory-detection-reboot: (36 commits) merge-recursive: fix check for skipability of working tree updates merge-recursive: make "Auto-merging" comment show for other merges merge-recursive: fix remainder of was_dirty() to use original index merge-recursive: fix was_tracked() to quit lying with some renamed paths t6046: testcases checking whether updates can be skipped in a merge merge-recursive: avoid triggering add_cacheinfo error with dirty mod merge-recursive: move more is_dirty handling to merge_content merge-recursive: improve add_cacheinfo error handling merge-recursive: avoid spurious rename/rename conflict from dir renames directory rename detection: new testcases showcasing a pair of bugs merge-recursive: fix remaining directory rename + dirty overwrite cases merge-recursive: fix overwriting dirty files involved in renames merge-recursive: avoid clobbering untracked files with directory renames merge-recursive: apply necessary modifications for directory renames merge-recursive: when comparing files, don't include trees merge-recursive: check for file level conflicts then get new name merge-recursive: add computation of collisions due to dir rename & merging merge-recursive: check for directory level conflicts merge-recursive: add get_directory_renames() merge-recursive: make a helper function for cleanup for handle_renames ...

merge-recursive: check for file level conflicts then get new name

2018-05-08T07:11:00Z

Before trying to apply directory renames to paths within the given directories, we want to make sure that there aren't conflicts at the file level either. If there aren't any, then get the new name from any directory renames. Reviewed-by: Stefan Beller Signed-off-by: Elijah Newren Signed-off-by: Junio C Hamano

Merge branch 'ls/checkout-encoding'

2018-05-08T06:59:22Z

The new "checkout-encoding" attribute can ask Git to convert the contents to the specified encoding when checking out to the working tree (and the other way around when checking in). * ls/checkout-encoding: convert: add round trip check based on 'core.checkRoundtripEncoding' convert: add tracing for 'working-tree-encoding' attribute convert: check for detectable errors in UTF encodings convert: add 'working-tree-encoding' attribute utf8: add function to detect a missing UTF-16/32 BOM utf8: add function to detect prohibited UTF-16/32 BOM utf8: teach same_encoding() alternative UTF encoding names strbuf: add a case insensitive starts_with() strbuf: add xstrdup_toupper() strbuf: remove unnecessary NUL assignment in xstrdup_tolower()

Revert "Merge branch 'en/rename-directory-detection'"

2018-04-11T09:07:11Z

This reverts commit e4bb62fa1eeee689744b413e29a50b4d1dae6886, reversing changes made to 468165c1d8a442994a825f3684528361727cd8c0. The topic appears to inflict severe regression in renaming merges, even though the promise of it was that it would improve them. We do not yet know which exact change in the topic was wrong, but in the meantime, let's play it safe and revert it out of 'master' before real Git-using projects are harmed.

strbuf: convert strbuf_add_unique_abbrev to use struct object_id

2018-03-14T16:23:48Z

Convert the declaration and definition of strbuf_add_unique_abbrev to make it take a pointer to struct object_id. Predeclare the struct in strbuf.h, as cache.h includes strbuf.h before it declares the struct, and otherwise the struct declaration would have the wrong scope. Apply the following semantic patch, along with the standard object_id transforms, to adjust the callers: @@ expression E1, E2, E3; @@ - strbuf_add_unique_abbrev(E1, E2.hash, E3); + strbuf_add_unique_abbrev(E1, &E2, E3); @@ expression E1, E2, E3; @@ - strbuf_add_unique_abbrev(E1, E2->hash, E3); + strbuf_add_unique_abbrev(E1, E2, E3); Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

strbuf: add xstrdup_toupper()

worktree move: accept destination as directory

2018-02-12T21:13:35Z

Similar to "mv a b/", which is actually "mv a b/a", we extract basename of source worktree and create a directory of the same name at destination if dst path is a directory. Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano
