cache-tree: verify valid cache-tree in the test suite
This makes sure that cache-tree is consistent with the index. The main
purpose is to catch potential problems by saving the index in
unpack_trees() but the line in write_index() would also help spot
missing invalidation in other code.

Any changes to the output index should be (confusingly) marked in the
source index with invalidate_ce_path(). This is used to make sure we
still have valid untracked cache and cache-tree extensions in the end.
We do a pretty good job of invalidating except in two places.
verify_clean_subdirectory() is part of verify_absent() and
verify_absent_sparse(). The former is usually called by merged_entry()
or directly in threeway_merge(). The latter is obviously used by
sparse checkout.
In these three call sites, only merged_entry() follows up with
invalidate_ce_path(). The other two don't, but they should not trigger
this ce removal because this is about D/F conflicts [1]. But let's be
safe and invalidate_ce_path() here as well.
The second place is keep_entry() which is also used by threeway_merge()
to keep higher stage entries. In order to reuse cache-tree we need to
invalidate these paths as well. It's not a problem in the past because
whenever a higher stage entry is present, cache-tree will not be
created [2]. Now we salvage cache-tree even when higher stage entries
are present, we need more invalidation.
[1] c81935348b (Fix switching to a branch with D/F when current branch
has file D. - 2007-03-15)
[2] This is probably too strict. We should be able to create and save
cache-tree for the directories that do not have conflict entries
in cache_tree_update(). And this becomes more important when
cache-tree plays bigger role in terms of performance.

unpack-trees: reuse (still valid) cache-tree from src_index
We do n-way merge by walking the source index and n trees at the same
time and add merge results to a new temporary index called o->result.
The merge result for any given path could be either
- keep_entry(): same old index entry in o->src_index is reused
- merged_entry(): either a new entry is added, or an existing one updated
- deleted_entry(): one entry from o->src_index is removed
For some reason [1] we keep making sure that the source index's
cache-tree is still valid if used by o->result: for all those
merged/deleted entries, we invalidate the same path in o->src_index,
so only cache-trees covering the "keep_entry" parts remain good.
Because of this, the cache-tree from o->src_index can be perfectly
reused in o->result. And in fact we already rely on this logic to
reuse untracked cache in edf3b90553 (unpack-trees: preserve index
extensions - 2017-05-08). Move the cache-tree to o->result before
doing cache_tree_update() to reduce hashing cost.
Since cache_tree_update() has risen up as one of the most expensive
parts in unpack_trees() after the last few patches. This does help
reduce unpack_trees() time significantly (on webkit.git):
[1] I'm pretty sure the reason is an oversight in 34110cd4e3 (Make
'unpack_trees()' have a separate source and destination index -
2008-03-06). That patch aims to _not_ update the source index at
all. The invalidation should have been done on o->result in that
patch. But then there was no cache-tree on o->result even then so
it's pointless to do so.

This is a micro optimization that probably only shines on repos with
deep directory structure. Instead of allocating and freeing a new

unpack-trees: optimize walking same trees with cache-tree
In order to merge one or many trees with the index, unpack-trees code
walks multiple trees in parallel with the index and performs n-way
merge. If we find out at start of a directory that all trees are the
same (by comparing OID) and cache-tree happens to be available for
that directory as well, we could avoid walking the trees because we
already know what these trees contain: it's flattened in what's called
"the index".
The upside is of course a lot less I/O since we can potentially skip
lots of trees (think subtrees). We also save CPU because we don't have
to inflate and apply the deltas. The downside is of course more
fragile code since the logic in some functions are now duplicated
elsewhere.
"checkout -" with this patch on webkit.git (275k files):
This command calls unpack_trees() twice, the first time on 2way merge
and the second 1way merge. In both times, "unpack trees" time is
reduced to one third. Overall time reduction is not that impressive of
course because index operations take a big chunk. And there's that
repair cache-tree line.
PS. A note about cache-tree invalidation and the use of it in this
code.
We do invalidate cache-tree in _source_ index when we add new entries
to the (temporary) "result" index. But we also use the cache-tree from
source index in this optimization. Does this mean we end up having no
cache-tree in the source index to activate this optimization?
The answer is twisted: the order of finding a good cache-tree and
invalidating it matters. In this case we check for a good cache-tree
first in all_trees_same_as_cache_tree(), then we start to merge things
and potentially invalidate that same cache-tree in the process. Since
cache-tree invalidation happens after the optimization kicks in, we're
still good. But we may lose that cache-tree at the very first
call_unpack_fn() call in traverse_by_cache_tree().

We're going to optimize unpack_trees() a bit in the following
patches. Let's add some tracing to measure how long it takes before
and after. This is the baseline ("git checkout -" on webkit.git, 275k
files on worktree)
Performance measurements are listed right now as a flat list, which is
fine when we measure big blocks. But when we start adding more and
more measurements, some of them could be just part of a bigger
measurement and a flat list gives a wrong impression that they are
executed at the same level instead of nested.
Add trace_performance_enter() and trace_performance_leave() to allow
indent these nested measurements. For now it does not help much
because the only nested thing is (lazy) name hash initialization
(e.g. called in diff-index from "git status"). This will help more
because I'm going to add some more tracing that's actually nested.

The caller of maybe_colorize_sideband() gives a counted buffer
<src, n>, but the callee checked src[] as if it were a NUL terminated
buffer. If src[] had all isspace() bytes in it, we would have made
n negative, and then
(1) made number of strncasecmp() calls to see if the remaining
bytes in src[] matched keywords, reading beyond the end of the
array (this actually happens even if n does not go negative),
and/or
(2) called strbuf_add() with negative count, most likely triggering
the "you want to use way too much memory" error due to unsigned
integer overflow.
Fix both issues by making sure we do not go beyond &src[n].
In the longer term we may want to accept size_t as parameter for
clarity (even though we know that a sideband message we are painting
typically would fit on a line on a terminal and int is sufficient).

filesystems, but if those repos are cloned in a case-insensitive one,
you'll get problems. The first thing to notice is "git status" will
never be clean with no indication what exactly is "dirty".
This patch helps the situation a bit by pointing out the problem at
clone time. Even though this patch talks about case sensitivity, the
patch makes no assumption about folding rules by the filesystem. It
simply observes that if an entry has been already checked out at clone
time when we're about to write a new path, some folding rules are
behind this.
In the case that we can't rely on filesystem (via inode number) to do
this check, fall back to fspathcmp() which is not perfect but should
not give false positives.
This patch is tested with vim-colorschemes and Sublime-Gitignore
repositories on a JFS partition with case insensitive support on
Linux.

Hosting providers that allow users to "fork" existing
repos want those forks to share as much disk space as
possible.
Alternates are an existing solution to keep all the
objects from all the forks into a unique central repo,
but this can have some drawbacks. Especially when
packing the central repo, deltas will be created
between objects from different forks.
This can make cloning or fetching a fork much slower
and much more CPU intensive as Git might have to
compute new deltas for many objects to avoid sending
objects from a different fork.
Because the inefficiency primarily arises when an
object is deltified against another object that does
not exist in the same fork, we partition objects into
sets that appear in the same fork, and define
"delta islands". When finding delta base, we do not
allow an object outside the same island to be
considered as its base.
So "delta islands" is a way to store objects from
different forks in the same repo and packfile without
having deltas between objects from different forks.
This patch implements the delta islands mechanism in
"delta-islands.{c,h}", but does not yet make use of it.
A few new fields are added in 'struct object_entry'
in "pack-objects.h" though.
The documentation will follow in a patch that actually
uses delta islands in "builtin/pack-objects.c".

rebase -i: fix SIGSEGV when 'merge <branch>' fails
If a merge command in the todo list specifies just a branch to merge
with no -C/-c argument then item->commit is NULL. This means that if
there are merge conflicts error_with_patch() is passed a NULL commit
which causes a segmentation fault when make_patch() tries to look it up.
This commit implements a minimal fix which fixes the crash and allows
the user to successfully commit a conflict resolution with 'git rebase
--continue'. It does not write .git/rebase-merge/patch,
.git/rebase-merge/stopped-sha or update REBASE_HEAD. To sensibly get the
hashes of the merge parents would require refactoring do_merge() to
extract the code that parses the merge parents into a separate function
which error_with_patch() could then use to write the parents into the
stopped-sha file. To create meaningful output make_patch() and 'git
rebase --show-current-patch' would also need to be modified to diff the
merge parent and merge base in this case.

knowing the size of a pointer to an enum, so we cannot just forward
declare an enum the way we can a struct. (Also, modern C++ compilers
apparently define forward declarations of an enum to either be useless

alloc: make allocate_alloc_state and clear_alloc_state more consistent
Since both functions are using the same data type, they should either both
refer to it as void *, or both use the real type (struct alloc_state *).
Opt for the latter.

I looped over the toplevel header files, creating a temporary two-line C
program for each consisting of
#include "git-compat-util.h"
#include $HEADER
This patch is the result of manually fixing errors in compiling those
tiny programs.

Commit e12a7ef597 ("rebase -i: Handle "combination of <n> commits" with
GETTEXT_POISON", 2018-04-27) changed the way that individual commit
messages are labelled when squashing commits together. In doing so a
regression was introduced where the numbering of the messages is off by
one. This commit fixes that and adds a test for the numbering.

The `chainlint` target compares actual output to expected output, where
the actual output is generated from files that are specifically checked
out with LF-only line endings. So the expected output needs to be
checked out with LF-only line endings, too.

Rendered documentation can be easier to read than raw text because
headings and emphasized phrases stand out. Add the missing markup and
Makefile rule required to render this design document using asciidoc.
Tested by running
make -C Documentation technical/partial-clone.html
and viewing the output in a browser.
