shallow.c: use '{commit,rollback}_shallow_file'
In bd0b42aed3 (fetch-pack: do not take shallow lock unnecessarily,
2019-01-10), the author noted that 'is_repository_shallow' produces
visible side-effect(s) by setting 'is_shallow' and 'shallow_stat'.
This is a problem for e.g., fetching with '--update-shallow' in a
shallow repository with 'fetch.writeCommitGraph' enabled, since the
update to '.git/shallow' will cause Git to think that the repository
isn't shallow when it is, thereby circumventing the commit-graph
compatibility check.
This causes problems in shallow repositories with at least shallow refs
that have at least one ancestor (since the client won't have those
objects, and therefore can't take the reachability closure over commits
when writing a commit-graph).
Address this by introducing thin wrappers over 'commit_lock_file' and
'rollback_lock_file' for use specifically when the lock is held over
'.git/shallow'. These wrappers (appropriately called
'commit_shallow_file' and 'rollback_shallow_file') call into their
respective functions in 'lockfile.h', but additionally reset validity
checks used by the shallow machinery.
Replace each instance of 'commit_lock_file' and 'rollback_lock_file'
with 'commit_shallow_file' and 'rollback_shallow_file' when the lock
being held is over the '.git/shallow' file.
As a result, 'prune_shallow' can now only be called once (since
'check_shallow_file_for_update' will die after calling
'reset_repository_shallow'). But, this is OK since we only call
'prune_shallow' at most once per process.

Signed-off-by: Jeff King <peff@peff.net> Reviewed-by: Taylor Blau <me@ttaylorr.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
When writing a layered commit-graph, the commit-graph machinery uses
'commit_graph_filenames_after' and 'commit_graph_hash_after' to keep
track of the layers in the chain that we are in the process of writing.
When the number of commit-graph layers shrinks, we initialize all
entries in the aforementioned arrays, because we know the structure of
the new commit-graph chain immediately (since there are no new layers,
there are no unknown hash values).
But when the number of commit-graph layers grows (i.e., that
'num_commit_graphs_after > num_commit_graphs_before'), then we leave
some entries in the filenames and hashes arrays as uninitialized,
because we will fill them in later as those values become available.
For instance, we rely on 'write_commit_graph_file's to store the
filename and hash of the last layer in the new chain, which is the one
that it is responsible for writing. But, it's possible that
'write_commit_graph_file' may fail, e.g., from file descriptor
exhaustion. In this case it is possible that 'git_mkstemp_mode' will
fail, and that function will return early *before* setting the values
for the last commit-graph layer's filename and hash.
This causes a number of upleasant side-effects. For instance, trying to
'free()' each entry in 'ctx->commit_graph_filenames_after' (and
similarly for the hashes array) causes us to 'free()' uninitialized
memory, since the area is allocated with 'malloc()' and is therefore
subject to contain garbage (which is left alone when
'write_commit_graph_file' returns early).
This can manifest in other issues, like a general protection fault,
and/or leaving a stray 'commit-graph-chain.lock' around after the
process dies. (The reasoning for this is still a mystery to me, since
we'd otherwise usually expect the kernel to run tempfile.c's 'atexit()'
handlers in the case of a normal death...)
To resolve this, initialize the memory with 'CALLOC_ARRAY' so that
uninitialized entries are filled with zeros, and can thus be 'free()'d
as a noop instead of causing a fault.

commit-graph.c: don't use discarded graph_name in error
When writing a commit-graph layer, we do so in a temporary file which is
renamed into place. If we fail to create a temporary file, for e.g.,
because we have too many open files, then 'git_mkstemp_mode' sets the
pattern to the empty string, in which case we get an error something
along the lines of:
error: unable to create ''
It's not useful to show the pattern here at all, since we (1) know the
pattern is well-formed, and (2) would have already shown the dirname

mailinfo.c: avoid strlen on strings that can contains NUL
We're passing buffer from strbuf to reencode_string,
which will call strlen(3) on that buffer,
and discard the length of newly created buffer.
Then, we compute the length of the return buffer to attach to strbuf.
During this process, we introduce a discrimination between mail
originally written in utf-8 and other encoding.
* if the email was written in utf-8, we leave it as is. If there is
a NUL character in that line, we complains loudly:
error: a NUL byte in commit log message not allowed.
* if the email was written in other encoding, we truncate the data as
the NUL character in that line, then we used the truncated line for
the metadata.
We can do better by reusing all the available information,
and call the underlying lower level function that will be called
indirectly by reencode_string. By doing this, we will also postpone
the NUL character processing to the commit step, which will
complains about the faulty metadata.

Merge branch 'rs/pull-options-sync-code-and-doc'
"git pull" shares many options with underlying "git fetch", but
some of them were not documented and some of those that would make
sense to pass down were not passed down.
* rs/pull-options-sync-code-and-doc:
pull: pass documented fetch options on
pull: remove --update-head-ok from documentation
The server-end of the v2 protocol to serve "git clone" and "git
fetch" was not prepared to see a delim packets at unexpected
places, which led to a crash.

Merge branch 'dr/midx-avoid-int-underflow'
When fed a midx that records no objects, some codepaths tried to
loop from 0 through (num_objects-1), which, due to integer
arithmetic wrapping around, made it nonsense operation with out of
bounds array accesses. The code has been corrected to reject such
an midx file.

Merge branch 'bk/p4-pre-edit-changelist'
"git p4" learned four new hooks and also "--no-verify" option to
bypass them (and the existing "p4-pre-submit" hook).

git-p4: add RCS keyword status message

git-p4: create new function run_git_hook
git-p4: rewrite prompt to be Windows compatible
The import-tars importer (in contrib/fast-import/) used to create
phony files at the top-level of the repository when the archive
contains global PAX headers, which made its own logic to detect and
omit the common leading directory ineffective, which has been
corrected.
