diff -c/--cc: do not mistake "resolved as deletion" as "use working tree"
The combined diff machinery can be used to compare:
- a merge commit with its parent commits;
- a working-tree file with multiple stages in an unmerged index; or
- a working-tree file with the HEAD and the index.
The internal function combine-diff.c:show_patch_diff() checked if it needs
to read the "result" from the working tree by looking at the object name
of the result --- if it is null_sha1, it read from the working tree.
This mistook a merge that records a deletion as the conflict resolution
as if it is a cue to read from the working tree. Pass this information
explicitly from the caller instead.
Noticed and reported by Johan Herland.

* maint-1.7.0:

fast-import: introduce "feature notes" command
Here is a 'feature' command for streams to use to require support for
the notemodify (N) command.
When the 'feature' facility was introduced (v1.7.0-rc0~95^2~4,
2009-12-04), the notes import feature was old news (v1.6.6-rc0~21^2~8,
2009-10-09) and it was not obvious it deserved to be a named feature.
But now that is clear, since all major non-git fast-import backends
lack support for it.
Details: on git version with this patch applied, any "feature notes"
command in the features/options section at the beginning of a stream
will be treated as a no-op. On fast-import implementations without
the feature (and older git versions), the command instead errors out
with a message like
This version of fast-import does not support feature notes.
So by declaring use of notes at the beginning of a stream, frontends
can avoid wasting time and other resources when the backend does not
support notes. (This would be especially important for backends that
do not support rewinding history after a botched import.)

fast-import: clarify documentation of "feature" command
The "feature" command allows streams to specify options for the import
that must not be ignored. Logically, they are part of the stream,
even though technically most supported features are synonyms to
command-line options.
Make this more obvious by being more explicit about how the analogy
between most "feature" commands and command-line options works. Treat
the feature (import-marks) that does not fit this analogy separately.

Documentation/githooks: post-rewrite-copy-notes never existed
The documentation for the post-rewrite hook contains a paragraph from
its early development, where the automatic notes copying facilities
were not part of the series and thus this had to be a hook. Later
versions of the series implemented notes copying as a core feature.
Thus mentioning post-rewrite-copy-notes was never correct. As the
other hooks do not have a "there is no default hook, but..." sentence
unless they ship a sample hook in either templates or contrib, we
simply remove the whole paragraph.

The section and variable names can be broken into
words using bumpyCaps in documentation as a hint to
the reader. These word breaks are not significant
at the level of code, since the section and variable

The name "add.ignore-errors" includes a dash, meaning a naive

fix git branch -m in presence of cross devices
When you have for example a bare repository stored on NFS, and that you
create new workdirs locally (using contrib's git-new-workdir), logs/refs
is a symlink to a different device. Hence when the reflogs are renamed,
all must happen below logs/refs or one gets cross device rename errors
like:
git branch -m foo
error: unable to move logfile logs/refs/heads/master to tmp-renamed-log: Invalid cross-device link
fatal: Branch rename failed
The fix is hence to use logs/refs/.tmp-renamed-log as a temporary log
name, instead of just tmp-renamed-log.

xdiff: optimise for no whitespace difference when ignoring whitespace.
In xdl_recmatch, do the memcmp to check if the two lines are equal before
checking if whitespace flags are set. If the lines are identical, then
there is no need to check if they differ only in whitespace.
This makes the common case (there is no whitespace difference) faster.
It costs the case where lines are the same length and contain
whitespace differences, but the common case is more than 20% faster.

unpack-trees: Make index lookahead less pessimal
When traversing trees with an index, the current index pointer
(o->cache_bottom) occasionally has to be temporarily advanced forwards to
match the traversal order of the tree, which is not the same as the sort
order of the index. The existing algorithm that did this (introduced in
730f72840cc50c523fe4cdd796ea2d2fc4571a28) would get "stuck" when the
cache_bottom was popped and then repeatedly check the same index entries
over and over. This represents a serious performance regression for
large repositories compared to the old "broken" traversal order.
This commit makes a simple change to mitigate this. Whenever
find_cache_pos sees that the current pos is also the cache_bottom, and
it has already been unpacked, it advances the cache_bottom as well as
the current pos. This prevents the above "sticking" behavior without
dramatically changing the algorithm.
In addition, this commit moves the unpacked check above the
ce_in_traverse_path() check. The simple bitmask check is cheaper, and
in the case described above will be firing quite a bit to advance the
cache_bottom after a tree pop.
This yields considerable performance improvements for large trees.
The following are the number of function calls for "git diff HEAD" on
the Linux kernel tree, with 33,307 files:
Symbol Calls Before Calls After
------------------- ------------ -----------
unpack_callback 35,332 35,332
find_cache_pos 37,357 37,357
ce_in_traverse_path 4,979,473 37,357
do_compare_entry 6,828,181 251,925
df_name_compare 6,828,181 251,925
And on a repository of 187,456 files:
Symbol Calls Before Calls After
------------------- ------------ -----------
unpack_callback 197,958 197,958
find_cache_pos 208,460 208,460
ce_in_traverse_path 37,308,336 208,460
do_compare_entry 156,950,469 2,690,626
df_name_compare 156,950,469 2,690,626
On the latter repository, user time for "git diff HEAD" was reduced from
5.58 to 0.42 seconds. This is compared to 0.30 seconds before the
traversal order fix was implemented.

cache_bottom was popped and then repeatedly check the same index entries
over and over. This represents a serious performance regression for
large repositories compared to the old "broken" traversal order.
This commit makes a simple change to mitigate this. Whenever
find_cache_pos sees that the current pos is also the cache_bottom, and
it has already been unpacked, it advances the cache_bottom as well as
the current pos. This prevents the above "sticking" behavior without
dramatically changing the algorithm.
In addition, this commit moves the unpacked check above the
ce_in_traverse_path() check. The simple bitmask check is cheaper, and
in the case described above will be firing quite a bit to advance the
cache_bottom after a tree pop.
This yields considerable performance improvements for large trees.
The following are the number of function calls for "git diff HEAD" on
the Linux kernel tree, with 33,307 files:
Symbol Calls Before Calls After
------------------- ------------ -----------
unpack_callback 35,332 35,332
find_cache_pos 37,357 37,357
ce_in_traverse_path 4,979,473 37,357
do_compare_entry 6,828,181 251,925
df_name_compare 6,828,181 251,925
And on a repository of 187,456 files:
Symbol Calls Before Calls After
------------------- ------------ -----------
unpack_callback 197,958 197,958
find_cache_pos 208,460 208,460
ce_in_traverse_path 37,308,336 208,460
do_compare_entry 156,950,469 2,690,626
df_name_compare 156,950,469 2,690,626
On the latter repository, user time for "git diff HEAD" was reduced from
5.58 to 0.42 seconds. This is compared to 0.30 seconds before the
traversal order fix was implemented.
