pack-revindex: hide the definition of 'revindex_entry'

Now that all 'find_revindex_position()' callers have been removed (and
converted to the more descriptive 'offset_to_pack_pos()'), it is almost
safe to get rid of 'find_revindex_position()' entirely. Almost, except
for the fact that 'offset_to_pack_pos()' calls
'find_revindex_position()'.
Inline 'find_revindex_position()' into 'offset_to_pack_pos()', and
then remove 'find_revindex_position()' entirely.
This is a straightforward refactoring with one minor snag.
'offset_to_pack_pos()' used to load the index before calling
'find_revindex_position()'. That means that by the time
'find_revindex_position()' starts executing, 'p->num_objects' can be
safely read. After inlining, be careful to not read 'p->num_objects'
until _after_ 'load_pack_revindex()' (which loads the index as a
side-effect) has been called.
Another small fix that is included is converting the upper- and
lower-bounds to be unsigned's instead of ints. This dates back to 92e5c77c37 (revindex: export new APIs, 2013-10-24)--ironically, the last
time we introduced new APIs here--but this unifies the types.

builtin/gc.c: guess the size of the revindex
'estimate_repack_memory()' takes into account the amount of memory
required to load the reverse index in memory by multiplying the assumed

Prepare for hiding the definition of 'struct revindex_entry' by removing

guess that one off_t and one uint32_t are required per object. Strictly

pack-revindex: introduce a new API
In the next several patches, we will prepare for loading a reverse index
either in memory (mapping the inverse of the .idx's contents in-core),
or directly from a yet-to-be-introduced on-disk format. To prepare for
that, we'll introduce an API that avoids the caller explicitly indexing
the revindex pointer in the packed_git structure.
There are four ways to interact with the reverse index. Accordingly,
four functions will be exported from 'pack-revindex.h' by the time that
the existing API is removed. A caller may:
1. Load the pack's reverse index. This involves opening up the index,
generating an array, and then sorting it. Since opening the index
can fail, this function ('load_pack_revindex()') returns an int.
Accordingly, it takes only a single argument: the 'struct
packed_git' the caller wants to build a reverse index for.
This function is well-suited for both the current and new API.
Callers will have to continue to open the reverse index explicitly,
but this function will eventually learn how to detect and load a
reverse index from the on-disk format, if one exists. Otherwise, it
will fallback to generating one in memory from scratch.
2. Convert a pack position into an offset. This operation is now
called `pack_pos_to_offset()`. It takes a pack and a position, and
returns the corresponding off_t.
Any error simply calls BUG(), since the callers are not well-suited
to handle a failure and keep going.
3. Convert a pack position into an index position. Same as above; this
takes a pack and a position, and returns a uint32_t. This operation
is known as `pack_pos_to_index()`. The same thinking about error
conditions applies here as well.
4. Find the pack position for a given offset. This operation is now
known as `offset_to_pack_pos()`. It takes a pack, an offset, and a
pointer to a uint32_t where the position is written, if an object
exists at that offset. Otherwise, -1 is returned to indicate
failure.
Unlike some of the callers that used to access '->offset' and '->nr'
directly, the error checking around this call is somewhat more
robust. This is important since callers should always pass an offset
which points at the boundary of two objects. The API, unlike direct
access, enforces that that is the case.
This will become important in a subsequent patch where a caller
which does not but could check the return value treats the signed
`-1` from `find_revindex_position()` as an index into the 'revindex'
array.
Two design warts are carried over into the new API:
- Asking for the index position of an out-of-bounds object will result
in a BUG() (since no such object exists), but asking for the offset
of the non-existent object at the end of the pack returns the total
size of the pack.
This makes it convenient for callers who always want to take the
difference of two adjacent object's offsets (to compute the on-disk
size) but don't want to worry about boundaries at the end of the
pack.
- offset_to_pack_pos() lazily loads the reverse index, but
pack_pos_to_index() doesn't (callers of the former are well-suited
to handle errors, but callers of the latter are not).

worktree: teach `repair` to fix multi-directional breakage
`git worktree repair` knows how to repair the two-way links between the
repository and a worktree as long as a link in one or the other
direction is sound. For instance, if a linked worktree is moved (without
using `git worktree move`), repair is possible because the worktree
still knows the location of the repository even though the repository no
longer knows where the worktree is. Similarly, if the repository is
moved, repair is possible since the repository still knows the locations
of the worktrees even though the worktrees no longer know where the
repository is.
However, if both the repository and the worktrees are moved, then links
are severed in both directions, and no repair is possible. This is the
case even when the new worktree locations are specified as arguments to
`git worktree repair`. The reason for this limitation is twofold. First,
when `repair` consults the worktree's gitfile (/path/to/worktree/.git)
to determine the corresponding <repo>/worktrees/<id>/gitdir file to fix,
<repo> is the old path to the repository, thus it is unable to fix the
`gitdir` file at its new location since it doesn't know where it is.
Second, when `repair` consults <repo>/worktrees/<id>/gitdir to find the
location of the worktree's gitfile (/path/to/worktree/.git), the path
recorded in `gitdir` is the old location of the worktree's gitfile, thus
it is unable to repair the gitfile since it doesn't know where it is.
Fix these shortcomings by teaching `repair` to attempt to infer the new
location of the <repo>/worktrees/<id>/gitdir file when the location
recorded in the worktree's gitfile has become stale but the file is
otherwise well-formed. The inference is intentionally simple-minded.
For each worktree path specified as an argument, `git worktree repair`
manually reads the ".git" gitfile at that location and, if it is
well-formed, extracts the <id>. It then searches for a corresponding
<id> in <repo>/worktrees/ and, if found, concludes that there is a
reasonable match and updates <repo>/worktrees/<id>/gitdir to point at
the specified worktree path. In order for <repo> to be known, `git
worktree repair` must be run in the main worktree or bare repository.
`git worktree repair` first attempts to repair each incoming
/path/to/worktree/.git gitfile to point at the repository, and then
attempts to repair outgoing <repo>/worktrees/<id>/gitdir files to point
at the worktrees. This sequence was chosen arbitrarily when originally
implemented since the order of fixes is immaterial as long as one side
of the two-way link between the repository and a worktree is sound.
However, for this new repair technique to work, the order must be
reversed. This is because the new inference mechanism, when it is
successful, allows the outgoing <repo>/worktrees/<id>/gitdir file to be
repaired, thus fixing one side of the two-way link. Once that side is
fixed, the other side can be fixed by the existing repair mechanism,
hence the order of repairs is now significant.
Two safeguards are employed to avoid hijacking a worktree from a
different repository if the user accidentally specifies a foreign
worktree as an argument. The first, as described above, is that it
requires an <id> match between the repository and the worktree. That
itself is not foolproof for preventing hijack, so the second safeguard
is that the inference will only kick in if the worktree's
/path/to/worktree/.git gitfile does not point at a repository.

Set a different background color for selections in inactive widgets.
This inactive color is calculated from the current theme colors to make
sure it works for all themes.

has been timed at 1.934s on my laptop (an old core i5-4200M @ 2.50GHz,
8GB RAM, 1TB HDD).
Notice that the Makefile, as part of processing the 'clean' target, is
updating the 'GIT-VERSION-FILE' file. This is to ensure that the
$(GITGUI_VERSION) make variable is set, once that file had been included.
However, the 'clean' target does not use the $(GITGUI_VERSION) variable,
so this is wasted effort.
In order to eliminate such wasted effort, use the value of the internal
$(MAKECMDGOALS) variable to only '-include GIT-VERSION-FILE' when the
target is not 'clean'. (This drops the time down to 0.676s, on my laptop,
giving an improvement of 65.05%).

git-gui: fix colored label backgrounds when using themed widgets
The aqua theme on Mac doesn't support changing the background color for labels
and frames [1]. Since the red, green, and yellow backgrounds of the labels for
unstaged and staged files and the diff pane are so important design elements of
git gui's main window, it's not acceptable for them to have grey backgrounds on
Mac.
To work around this, simply use non-themed widgets for all labels on Mac. This
is not a big problem because labels don't look extremely different between the
themed and non-themed versions. There are subtle differences, but they are not
as bad as having the wrong background color.
config.mak.uname: remove old NonStop compatibility settings
The MKDIR_WO_TRAILING_SLASH and NO_SETITIMER options are no longer
needed on the NonStop platforms as both are now supported by the
oldest supported operating system revision.

merge-ort: implement merge_incore_recursive()
Implement merge_incore_recursive(), mostly through the use of a new
helper function, merge_ort_internal(), which itself is based off
merge_recursive_internal() from merge-recursive.c.
This drops the number of failures in the testsuite when run under
GIT_TEST_MERGE_ALGORITHM=ort from around 1500 to 647.

merge-ort: make clear_internal_opts() aware of partial clearing
In order to handle recursive merges, after merging merge-bases we need
to clear away most of the data we had built up but some of it needs to
be kept -- in particular the "output" field. Rename the function to
reflect its future change in use.
Further, since "reinitialize" means we'll be reusing the fields
immediately, take advantage of this to only partially clear maps,
leaving the hashtable allocated and pre-sized. (This may be slightly
out-of-order since the speedups aren't realized until there are far
more strmaps in use, but the patch submission process already went out
of order because of various questions and requests for strmap. Anyway,
see commit 6ccdfc2a20 ("strmap: enable faster clearing and reusing of
strmaps", 2020-11-05), for performance details about the use of
strmap_partial_clear().)

merge-ort: copy a few small helper functions from merge-recursive.c
In a subsequent commit, we will implement the traditional recursiveness
that gave merge-recursive its name, namely merging non-unique
merge-bases to come up with a single virtual merge base. Copy a few
helper functions from merge-recursive.c that we will use in the
implementation.

pack-redundant: fix crash when one packfile in repo
Command `git pack-redundant --all` will crash if there is only one
packfile in the repository. This is because, if there is only one
packfile in local_packs, `cmp_local_packs` will do nothing and will
leave `pl->unique_objects` as uninitialized.
Also add testcases for repository with no packfile and one packfile
in t5323.
