fix unrelated changes being merged by got cherrypick/backout/rebase/histedit This was a long-standing and very annoying bug. The two xfail tests in the cherrypick test suite are passing now.

switch merge_file_cb() to using merge_file() instead of merge_blob()

decouple merge_file() parameters for 2nd derived version and merge target file

in merge_file(), remove allocation of a base_path which is unused

move merge_file()'s f_deriv parameter next to the f_orig parameter

make merge_file() accept FILEs instead of paths for orig and deriv inputs

refactor merge_file() such that it no longer requires a blob object parameter

do not update symlinks which are already up-to-date This fixes spurious 'U' notifications for symlinks during 'got update' that occurred even when the work tree was fully up-to-date. Observed on a work tree of the FreeBSD src repo and reproduced in our test suite by adding a no-op update at the end of a test which deals with updating symlinks.

add a missing STATUS_EXISTS notification in update_blob()

fix use of an uninitialized stat buffer during work tree status crawl found by naddy ok naddy jrick

ensure that old commits remain referenced after rebase and histedit Create automatic "backup" references which ensure that objects from the pre-rebase or pre-histedit state remain in the repository. A new -l option for 'got rebase' and 'got histedit' lists old commits. This makes it easier to recover from botched rebase or histedit operations. Removal of such objects currently requires got ref -d and git-gc. This will be made more convenient in the future. testing and ok jrick

implicitly mark all files in work tree as up-to-date after 'got integrate' Avoids having to run 'got update' for no good reason after 'got integrate'. The same change was made recently for both rebase and histedit in commit a615e0e7796ea1103a6e0d4b5dbb6134597886660 and we forgot about histedit.

close file handles before freeing other things in got_worktree_close() The work tree's path needs to be valid while constructing error messages.

fix missing close(2) error check in got_worktree_close()

make close(2) failure checks consistent; check 'close() == -1' everywhere ok millert, naddy

make fclose(3) failure checks consistent; check 'fclose() == EOF' everywhere ok millert, naddy

add missing braces around multi-line if-statement in got_worktree_close()

fix a use after free() ok jrick stsp

replace fparseln(3) with getline(3), for better portability ok stsp

implicitly mark all files in work tree as up-to-date after rebase/histedit This should always be correct, since rebase and histedit start out with a clean and single-base-commit worktree, and end up committing all changes across the entire work tree when they are successful. tested by jrick and myself

add fd field to got_worktree, modify got_fileindex_entry_update to use fds These changes are intended to make got more compatible with FreeBSD's Capsicum. ok stsp

handle binary files in got/tog diff commands; add -a options to force text

merge new diff implementation from the git.gameoftrees.org diff.git repository This new diff implementation was started by Neels Hofmeyr during the u2k20 hackathon and now replaces diffreg.c code lifted from the OpenBSD base system. The integration of this code into Got was done by me. Got now uses the patience diff algorithm by default. The diff.git repository will remain the primary repository for the diff code, which already compiles and runs on other operating systems such as Linux. Any fixes and improvements for files inherited from the diff.git repository should be written against that repository and synced to got.git afterwards.

fix replacing symlinks with files And add a test case which verifies that the inverse also works, i.e. a symlink being replaced with a regular file. problem reported and fix tested by jrick

fix missing unlink(tmppath) in error cases of install_blob()
