got patch: handle the removal of binary files

Diffs that remove binary files don't have hunks so got patch would skip over them, treating that part of the diff as "noise". Different programs outputs a slightly different diff for this kind of patches, but the "Binary files ... and /dev/null differ" is usually shown, so try to match it. The adedd regress test covers got diff, git diff, and OpenBSD' /usr/bin/diff. CVS diffs will currently fail because the guessed file name will be wrong. CVS prints the file name in the Index and RCS lines which got patch currently ignores, and shows an useless path in the "Binary files /tmp/cvs... and /dev/null differ" line. Discussed with and ok stsp@


Thomas Adam

use mkstemps(3) instead of mkstemp(3) for opening named temporary files

Allows 'got commit' to use a ".diff" suffix for temporary diff files. ok op@


Thomas Adam

respect umask when creating or changing files and directories

This behaviour is already documented in got-worktree(5) but wasn't actually implemented. ok stsp@



Thomas Adam

ensure got patch respects x-bit perms for new files

Reported by stsp on IRC: got patch failed to set the x-bit for a new file despite got diff recording mode 755. Parse got and git diffs for this data and set file modes accordingly. Tweaked with hint from op. ok stsp@

locate_hunk: set mangled earlier for clarity

suggested by stsp@; no functional change.



Thomas Adam

got patch: add -c flag to apply at a specified commit

it's useful for e.g. to apply old patches that weren't generated by `got diff' or git-diff(1) and so lacks the metadata needed for the 3-way merge. manpage improvements from and ok stsp@


Thomas Adam

simplify got_patch/apply_patch to call reverse_patch in one place once

Current code is overly complex; it looks if the diff *might* use diff3 merge to postpone reverse_patch until we know for sure. Instead, just reverse_patch in apply_patch once we know if merge *is* used or not.


Thomas Adam

fix `got patch -R' when using diff3 merge

`got patch -R' fails spectacularly when applied on a diff that contains the info of the original blob for the diff3 merge machinery since it tries to apply the reverse of the patch to the old blob. change it to run the patch (_not_ reversed) on the old blob and then swap the arguments to got_diff3_merge which gives us the correct reverse merge of the diff. while here add a test case too. reported by naddy, discussed with and ok stsp@


Thomas Adam

portable: add back sys/queue.h

Now that the handling of including sys/queue.h is better, there's no need to remove those lines from the source. Copy the location of those original sys/queue.h lines from upstream at the same line number, so as to avoid any conflicts in the future.


Thomas Adam

use got_privsep_flush_imsg instead of reinventing it

ok stsp@


Thomas Adam

check for specific chars instead of using isspace(3)

Reminded by naddy and stsp; it was missing a cast to unsigned char to prevent issues on archs with signed chars and was too broad anyway. While here, drop an extra check immediately after. ok stsp@


Thomas Adam

got patch: handle mangled whitespaces

This makes 'got patch' try to ignore whitespaces when trying to match a hunk. Discused with and ok stsp@


Thomas Adam

got patch: don't loose the x bit when merging with diff3

This fixes a regression introduced with the diff3 merge: files merged this way have their permissions resetted after patch. The issue is due the fact that patch_file looks at a temporary files and not at the original "old file". Reported by and ok stsp@


Thomas Adam

switch 'tog diff' and 'tog blame' to Myers diff for speed

Make the choice of diff algorithm configurable by diff API users. The got and gotweb programs keep using Patience diffs which are prettier than Myers. But tog should be as fast as possible since it is being used interactively. If performance of Patience diff gets improved later we can consider switching tog back over to it. ok tracey jamsek



Thomas Adam

got patch: handle git-style diffs for the 3-way merge too

tweak and ok stsp@


Thomas Adam

handle blob ids without corresponding blob ids

ok stsp@


Thomas Adam

got patch: use status G for merged files (and document it)

Suggested by stsp@. This makes possible to tell if 'got patch' used a merge-base from the repository for the 3-way merge or did a simple search/replace operation. While here update the tests to look for the 'G' status and the manpage, which was also missing the documentation for the 'C' status in got patch. ok stsp@


Thomas Adam

got patch: ignore blobs not found

since diffs are often enclosed in other formats (e.g. emails) we might parse something and think it's a blob id when it's not. This should already happens, but apply_patch is looking for the wrong error due to a leftover from previous attempts. Reported by stsp@ while here tweak the test_patch_merge_unknown_blob to also try with a dummy commit id, as now got-read-patch requires it in order to consider a blob id. ok stsp@


Thomas Adam

use the commitid in the patch diff3 conflict header

suggested by and ok stsp@


Thomas Adam

got patch: use diff3 to merge the changes

Parse the "blob -" metadata in diffs produced by 'got diff' and use the original file for patching. Then, use the diff3 with the current version of the file to merge the differences. This solves many failures automagically or at least turns them into a conflict. ok/improvements stsp@


Thomas Adam

patch_file: fill tmp with the patched file even in nop mode

future work with diff3 merge will need the fully patched file even in the nop mode ok stsp@


Thomas Adam

patch_file: move file ownership to parent
