rerere: make rr-cache fanout directory honor umask
This is the last remaining call to mkdir(2) that restricts the permission
bits by passing 0755. Just use the same mkdir_in_gitdir() used to create
the leaf directories.
Now we have all the necessary logic to fall back on three-way merge when
the patch does not cleanly apply, insert the conflicted entries to the
index as appropriate. This obviously triggers only when the "--index"
option is used.
When we fall back to three-way merge and some of the merges fail, just
like the case where the "--reject" option was specified and we had to
write some "*.rej" files out for unapplicable patches, exit the command
with non-zero status without showing the diffstat and summary. Otherwise
they would make the list of problematic paths scroll off the display.
When a patch wants to create a path, but we already have it in our
current state, pretend as if the patch and we independently added
the same path and cause add/add conflict, so that the user can
resolve it just like "git merge" in the same situation.
For that purpose, implement load_current() in terms of the
load_patch_target() helper introduced earlier to read the current
contents from the path given by patch->new_name (patch->old_name is
NULL for a creation patch).
When a patch does not apply to what we have, but we know the preimage the
patch was made against, we apply the patch to the preimage to compute what
the patch author wanted the result to look like, and attempt a three-way
merge between the result and our version, using the intended preimage as
the base version.
When we are applying the patch using the index, we would additionally need
to add the object names of these three blobs involved in the merge, which
is not yet done in this step, but we add a field to "struct patch" so that
later write-out step can use it.
Grab the preimage blob the patch claims to be based on out of the object
store, apply the patch, and then call three-way-merge function. This step
still does not plug the actual three-way merge logic yet, but we are
getting there.
Begin teaching the three-way merge fallback logic "git am -3" uses
to the underlying "git apply". It only implements the command line
parsing part, and does not do anything interesting yet, other than
making sure that "--reject" and "--3way" are not given together, and
making "--3way" imply "--index".
apply: move "already exists" logic to check_to_create()
The check_to_create_blob() function used to check only the case
where we are applying to the working tree. Rename the function to
check_to_create() and make it also responsible for checking the case
where we apply to the index. Also make its caller responsible for
issuing an error message.
load_preimage() is very specific to grab the current contents for
the path given by patch->old_name. Split the logic that grabs the
contents for a path out of it into a separate load_patch_target()
function.
The code to grab the result of application of a previous patch in the
input was mixed with error message generation for a case where a later
patch tries to modify contents of a path that has been removed.
The same code is duplicated elsewhere in the code. Introduce a helper
to clarify what is going on.
apply: factor out checkout_target() helper function
When a patch wants to touch a path, if the path exists in the index
but is missing in the working tree, "git apply --index" checks out
the file to the working tree from the index automatically and then
applies the patch.
Split this logic out to a separate helper function.
Reading a blob out of the object store does not have to require that the
caller has a cache entry for it.
Create a read_blob_object() helper function that takes the object name and
mode, and use it to reimplement the original function as a thin wrapper to
it.
The clear_image() function did not clear the line table in the image
structure; this does not matter for the current callers, as the function
is only called from the codepaths that deal with binary patches where the
line table is never populated, and the codepaths that do populate the line
table free it themselves.
But it will start to matter when we introduce a codepath to retry a failed
patch, so make sure it clears and frees everything.
The code is littered with to_be_deleted() whose purpose is not so clear.
Describe where it matters. Also remove an extra space before "#define"
that snuck in by mistake at 7fac0ee (builtin-apply: keep information about
files to be deleted, 2009-04-11).
This check is not only about type-change (for which it would be
sufficient to check only was_deleted()) but is also about a swap
rename. Otherwise to_be_deleted() check is not justified.
Restore umasks influence on the permissions of work tree created by clone
The original version of the git-clone just used mkdir(1) to create
the working directories. The version rewritten in C creates all
directories inside the working tree by using the mode argument of
0777 when calling mkdir(2) to let the umask take effect.
But the top-level directory of the working tree is created by
passing the mode argument of 0755 to mkdir(2), which results in an
overly tight restriction if the user wants to make directories group
writable with a looser umask like 002.

Makefile: apply dependencies consistently to sparse/asm targets
When a C file "foo.c" depends on a generated header file, we
note the dependency for the "foo.o" target. However, we
should also note it for other targets that are built from
foo.c, like "foo.sp" and "foo.s". These tend to be missed
because the latter two are not part of the default build,
and are typically built after a regular build which will
generate the header. Let's be consistent about including
them in dependencies.
This also makes us more consistent with nearby lines which
tack on EXTRA_CPPFLAGS when building certain files. These
flags may sometimes require extra dependencies to be added
(e.g., like GIT-VERSION-FILE; this is not the case for any
of the updated lines in this patch, but it is establishing a
style that will be used in later patches). Technically the
".sp" and ".s" targets do not care about these dependencies,
because they are force-built (".sp" because it is a phony
target, and ".s" because we explicitly force a rebuild).
Since the blocks in question are about communicating "things
built from foo.c depend on these flags", it frees the reader
from having to know or care more about how those targets are
implemented, and why it is OK for only "foo.o" to depend on
GIT-VERSION-FILE while "foo.sp" and "foo.s" both are
impacted by $(GIT_VERSION). And it helps future-proof us if
those force-build details should ever change.
This patch explicitly does not update the static header
dependencies used when COMPUTED_HEADER_DEPENDENCIES is off.
They are similar to the GIT-VERSION-FILE case above, in that
technically "foo.s" would depend on its included headers,
but it is irrelevant because we force-build it anyway. So it
would be tempting to update them in the same way (for
readability and future-proofing). However, those rules are
meant as a fallback to the computed header dependencies,
which do not handle ".s" and ".sp" at all (and are a much
harder problem to solve, as gcc is the one generating those
dependency lists).
So let's leave that harder problem until (and if) somebody
wants to change the ".sp" and ".s" rules, and keep the
static header dependencies consistent with the computed
ones.

Mac OS X mangles file names containing unicode on file systems HFS+,
VFAT or SAMBA. When a file using unicode code points outside ASCII
is created on a HFS+ drive, the file name is converted into
decomposed unicode and written to disk. No conversion is done if
the file name is already decomposed unicode.
Calling open("\xc3\x84", ...) with a precomposed "Ä" yields the same
result as open("\x41\xcc\x88",...) with a decomposed "Ä".
As a consequence, readdir() returns the file names in decomposed
unicode, even if the user expects precomposed unicode. Unlike on
HFS+, Mac OS X stores files on a VFAT drive (e.g. an USB drive) in
precomposed unicode, but readdir() still returns file names in
decomposed unicode. When a git repository is stored on a network
share using SAMBA, file names are send over the wire and written to
disk on the remote system in precomposed unicode, but Mac OS X
readdir() returns decomposed unicode to be compatible with its
behaviour on HFS+ and VFAT.
The unicode decomposition causes many problems:
- The names "git add" and other commands get from the end user may
often be precomposed form (the decomposed form is not easily input
from the keyboard), but when the commands read from the filesystem
to see what it is going to update the index with already is on the
filesystem, readdir() will give decomposed form, which is different.
- Similarly "git log", "git mv" and all other commands that need to
compare pathnames found on the command line (often but not always
precomposed form; a command line input resulting from globbing may
be in decomposed) with pathnames found in the tree objects (should
be precomposed form to be compatible with other systems and for
consistency in general).
- The same for names stored in the index, which should be
precomposed, that may need to be compared with the names read from
readdir().
NFS mounted from Linux is fully transparent and does not suffer from
the above.
As Mac OS X treats precomposed and decomposed file names as equal,
we can
- wrap readdir() on Mac OS X to return the precomposed form, and
- normalize decomposed form given from the command line also to the
precomposed form,
to ensure that all pathnames used in Git are always in the
precomposed form. This behaviour can be requested by setting
"core.precomposedunicode" configuration variable to true.
The code in compat/precomposed_utf8.c implements basically 4 new
functions: precomposed_utf8_opendir(), precomposed_utf8_readdir(),
precomposed_utf8_closedir() and precompose_argv(). The first three
are to wrap opendir(3), readdir(3), and closedir(3) functions.
The argv[] conversion allows to use the TAB filename completion done
by the shell on command line. It tolerates other tools which use
readdir() to feed decomposed file names into git.
When creating a new git repository with "git init" or "git clone",
"core.precomposedunicode" will be set "false".
The user needs to activate this feature manually. She typically
sets core.precomposedunicode to "true" on HFS and VFAT, or file
systems mounted via SAMBA.

The idiom tells the compiler to leave the variable uninitialized,
which saves a few bytes of code size, and, more importantly, allows
valgrind to check at runtime that the variable is properly initialized
by the time it is used.
But MSVC and clang do not know that idiom, so let's avoid it in

push: don't guess at qualifying remote refs on deletion
When we try to push a ref and the right-hand side of the
refspec does not find a match, we try to create it. If it is
not fully qualified, we try to guess where it would go in
the refs hierarchy based on the left-hand source side. If
the source side is not a ref, then we give up and give a
long explanatory message.
For deletions, however, this doesn't make any sense. We
would never want to create on the remote side, and if an
unqualified ref can't be matched, it is simply an error. The
current code handles this already because the left-hand side
is empty, and therefore does not give us a hint as to where
the right-hand side should go, and we properly error out.
Unfortunately, the error message is the long "we tried to
qualify this, but the source side didn't let us guess"
message, which is quite confusing.
Instead, we can just be more succinct and say "we can't
delete this because we couldn't find it". So before:
$ git push origin :bogus
error: unable to push to unqualified destination: bogus
The destination refspec neither matches an existing ref on the remote nor
begins with refs/, and we are unable to guess a prefix based on the source ref.
error: failed to push some refs to '$URL'
and now:
$ git push origin :bogus
error: unable to delete 'bogus': remote ref does not exist
error: failed to push some refs to '$URL'
It is tempting to also catch a fully-qualified ref like
"refs/heads/bogus" and generate the same error message.
However, that currently does not error out at all, and
instead gets sent to the remote side, which typically
generates a warning:
$ git push origin:refs/heads/bogus
remote: warning: Deleting a non-existent ref.
To $URL
- [deleted] bogus
While it would be nice to catch this error early, a
client-side error would mean aborting the push entirely and
changing push's exit code. For example, right now you can
do:
$ git push origin refs/heads/foo refs/heads/bar
and end up in a state where "foo" and "bar" are deleted,
whether both of them currently exist or not (and see an
error only if we actually failed to contact the server).
Generating an error would cause a regression for this use
case.

This fixes two formatting bugs in the git-config documentation:
- in the column.ui entry don't indent the last paragraph so that it isn't
formatted as a literal paragraph
- in the push.default entry separate the last paragraph from the
nested list.

sha1_name.c: teach get_short_sha1() a commit-only option
When the caller knows that the parameter is meant to name a commit,
e.g. "56789a" in describe name "v1.2.3-4-g56789a", pass that as a
hint so that lower level can use it to disambiguate objects when
there is only one commit whose name begins with 56789a even if there
are objects of other types whose names share the same prefix.
sha1_name.c: allow get_short_sha1() to take other flags
Instead of a separate "int quietly" argument, make it take "unsigned
flags" so that we can pass other options to it.
The bit assignment of this flag word is exposed in cache.h because
the mechanism will be exposed to callers of the higher layer in
later commits in this series.
In finish_object_disambiguation(), if the candidate hasn't been
checked, there are two cases:
- It is the first and only object that match the prefix; or
- It replaced another object that matched the prefix but that
object did not satisfy ds->fn() callback.
And the former case we set ds->candidate_ok to true without doing
anything else, while for the latter we check the candidate, which
may set ds->candidate_ok to false.
At this point in the code, ds->candidate_ok can be false only if
this last-round check found that the candidate does not pass the
check, because the state after update_candidates() returns cannot
satisfy
Hence, when we execute this "return", we know we have seen more than
one object that match the prefix (and none of them satisfied ds->fn),
meaning that we should say "the short name is ambiguous", not "there
is no object that matches the prefix".
sha1_name.c: restructure disambiguation of short names
We try to find zero, one or more matches from loose objects and
packed objects independently and then decide if the given short
object name is unique across them.
Instead, introduce a "struct disambiguate_state" that keeps track of
what we have found so far, that can be one of:
- We have seen one object that _could_ be what we are looking for;
- We have also checked that object for additional constraints (if any),
and found that the object satisfies it;
- We have also checked that object for additional constraints (if any),
and found that the object does not satisfy it; or
- We have seen more than one objects that satisfy the constraints.
and pass it to the enumeration functions for loose and packed
objects. The disambiguation state can optionally take a callback
function that takes a candidate object name and reports if the
object satisifies additional criteria (e.g. when the caller knows
that the short name must refer to a commit, this mechanism can be
used to check the type of the given object).
Compared to the earlier attempt, this round avoids the optional
check if there is only one candidate that matches the short name in
the first place.
sha1_name.c: correct misnamed "canonical" and "res"
These are hexadecimal and binary representation of the short object
name given to the callchain as its input. Rename them with _pfx
suffix to make it clear they are prefixes, and call them hex and bin
respectively.
There are only two callers, and they will benefit from being able to
pass disambiguation hints to underlying get_sha1_with_context() API
once it happens.
The only external caller is setup.c that tries to give a nicer error
message when an object name is misspelt (e.g. "HEAD:cashe.h").
Retire it and give the caller a dedicated and more intuitive API
function maybe_die_on_misspelt_object_name().
