Ramsay Jones 5bc8b5d5c1 Makefile: conditionally include GIT-VERSION-FILE
The 'clean' target is noticeably slow on cygwin, even for a 'do-nothing'
invocation of 'make clean'. For example, the second 'make clean' given
below:

  $ make clean >/dev/null 2>&1
  $ make clean
  GITGUI_VERSION = 0.21.0.85.g3e5c
  rm -rf git-gui lib/tclIndex po/*.msg
  rm -rf GIT-VERSION-FILE GIT-GUI-VARS
  $

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%).

Stefan Haller f9481b195b 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.

Elijah Newren 43e9c4eecc 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().)

Eric Sunshine f4698738f9 t/perf: fix test_export() failure with BSD sed
test_perf() runs each test in its own subshell which makes it difficult
to persist variables between tests. test_export() addresses this
shortcoming by grabbing the values of specified variables after a test
runs but before the subshell exits, and writes those values to a file
which is loaded into the environment of subsequent tests.

To grab the values to be persisted, test_export() pipes the output of
the shell's builtin `set` command through `sed` which plucks them out
using a regular expression along the lines of `s/^(var1|var2)/.../p`.
Unfortunately, though, this use of alternation is not portable. For
instance, BSD-lineage `sed` (including macOS `sed`) does not support it
in the default "basic regular expression" mode (BRE). It may be possible
to enable "extended regular expression" mode (ERE) in some cases with
`sed -E`, however, `-E` is neither portable nor part of POSIX.

Fortunately, alternation is unnecessary in this case and can easily be
avoided, so replace it with a series of simple expressions such as
`s/^var1/.../p;s/^var2/.../p`.

While at it, tighten the expressions so they match the variable names
exactly rather than matching prefixes (i.e. use `s/^var1=/.../p`).

If the requirements of test_export() become more complex in the future,
then an alternative would be to replace `sed` with `perl` which supports
alternation on all platforms, however, the simple elimination of
alternation via multiple `sed` expressions suffices for the present.

Elijah Newren 6fcccbd755 merge-ort: add implementation of type-changed rename handling
Implement cases where renames are involved in type changes (i.e. the
side of history that didn't rename the file changed its type from a
regular file to a symlink or submodule).  There was some code to handle
this in merge-recursive but only in the special case when the renamed
file had no content changes.  The code here works differently -- it
knows process_entry() can handle mode conflicts, so it does a few
minimal tweaks to ensure process_entry() can just finish the job as
needed.

Elijah Newren f1665e6918 merge-ort: add implementation of normal rename handling
Implement handling of normal renames.  This code replaces the following
from merge-recurisve.c:

  * the code relevant to RENAME_NORMAL in process_renames()
  * the RENAME_NORMAL case of process_entry()

Also, there is some shared code from merge-recursive.c for multiple
different rename cases which we will no longer need for this case (or
other rename cases):

  * handle_rename_normal()
  * setup_rename_conflict_info()

The consolidation of four separate codepaths into one is made possible
by a change in design: process_renames() tweaks the conflict_info
entries within opt->priv->paths such that process_entry() can then
handle all the non-rename conflict types (directory/file, modify/delete,
etc.) orthogonally.  This means we're much less likely to miss special
implementation of some kind of combination of conflict types (see
commits brought in by 66c62eaec6 ("Merge branch 'en/merge-tests'",
2020-11-18), especially commit ef52778708 ("merge tests: expect improved
directory/file conflict handling in ort", 2020-10-26) for more details).
That, together with letting worktree/index updating be handled
orthogonally in the merge_switch_to_result() function, dramatically
simplifies the code for various special rename cases.

(To be fair, the code for handling normal renames wasn't all that
complicated beforehand, but it's still much simpler now.)

Elijah Newren 35e47e3514 merge-ort: add implementation of rename collisions
Implement rename/rename(2to1) and rename/add handling, i.e. a file is
renamed into a location where another file is added (with that other
file either being a plain add or itself coming from a rename).  Note
that rename collisions can also have a special case stacked on top: the
file being renamed on one side of history is deleted on the other
(yielding either a rename/add/delete conflict or perhaps a
rename/rename(2to1)/delete[/delete]) conflict.

One thing to note here is that when there is a double rename, the code
in question only handles one of them at a time; a later iteration
through the loop will handle the other.  After they've both been
handled, process_entry()'s normal add/add code can handle the collision.

This code replaces the following from merge-recurisve.c:

  * all the 2to1 code in process_renames()
  * the RENAME_TWO_FILES_TO_ONE case of process_entry()
  * handle_rename_rename_2to1()
  * handle_rename_add()

Also, there is some shared code from merge-recursive.c for multiple
different rename cases which we will no longer need for this case (or
other rename cases):

  * handle_file_collision()
  * setup_rename_conflict_info()

The consolidation of six separate codepaths into one is made possible
by a change in design: process_renames() tweaks the conflict_info
entries within opt->priv->paths such that process_entry() can then
handle all the non-rename conflict types (directory/file, modify/delete,
etc.) orthogonally.  This means we're much less likely to miss special
implementation of some kind of combination of conflict types (see
commits brought in by 66c62eaec6 ("Merge branch 'en/merge-tests'",
2020-11-18), especially commit ef52778708 ("merge tests: expect improved
directory/file conflict handling in ort", 2020-10-26) for more details).
That, together with letting worktree/index updating be handled
orthogonally in the merge_switch_to_result() function, dramatically
simplifies the code for various special rename cases.

Elijah Newren 2e91ddd24e merge-ort: add implementation of rename/delete conflicts
Implement rename/delete conflicts, i.e. one side renames a file and the
other deletes the file.  This code replaces the following from
merge-recurisve.c:

  * the code relevant to RENAME_DELETE in process_renames()
  * the RENAME_DELETE case of process_entry()
  * handle_rename_delete()

Also, there is some shared code from merge-recursive.c for multiple
different rename cases which we will no longer need for this case (or
other rename cases):

  * handle_change_delete()
  * setup_rename_conflict_info()

The consolidation of five separate codepaths into one is made possible
by a change in design: process_renames() tweaks the conflict_info
entries within opt->priv->paths such that process_entry() can then
handle all the non-rename conflict types (directory/file, modify/delete,
etc.) orthogonally.  This means we're much less likely to miss special
implementation of some kind of combination of conflict types (see
commits brought in by 66c62eaec6 ("Merge branch 'en/merge-tests'",
2020-11-18), especially commit ef52778708 ("merge tests: expect improved
directory/file conflict handling in ort", 2020-10-26) for more details).
That, together with letting worktree/index updating be handled
orthogonally in the merge_switch_to_result() function, dramatically
simplifies the code for various special rename cases.

To be fair, there is a _slight_ tweak to process_entry() here, because
rename/delete cases will also trigger the modify/delete codepath.
However, we only want a modify/delete message to be printed for a
rename/delete conflict if there is a content change in the renamed file
in addition to the rename.  So process_renames() and process_entry()
aren't quite fully orthogonal, but they are pretty close.

Elijah Newren 53e88a0353 merge-ort: add implementation of both sides renaming differently
Implement rename/rename(1to2) handling, i.e. both sides of history
renaming a file and rename it differently.  This code replaces the
following from merge-recurisve.c:

  * all the 1to2 code in process_renames()
  * the RENAME_ONE_FILE_TO_TWO case of process_entry()
  * handle_rename_rename_1to2()

To be fair, there is a _slight_ tweak to process_entry() here to make
sure that the two different paths aren't marked as clean but are left in
a conflicted state.  So process_renames() and process_entry() aren't
quite entirely orthogonal, but they are pretty close.

Elijah Newren af1e56c49e merge-ort: add implementation of both sides renaming identically
Implement rename/rename(1to1) handling, i.e. both sides of history
renaming a file but renaming the same way.  This code replaces the
following from merge-recurisve.c:

  * all the 1to1 code in process_renames()
  * the RENAME_ONE_FILE_TO_ONE case of process_entry()

Also, there is some shared code from merge-recursive.c for multiple
different rename cases which we will no longer need for this case (or

entries within opt->priv->paths such that process_entry() can then
