Internaly we use 0{40} as a placeholder object name to signal the
codepath that there is no such object (e.g. the fast-forward check
while "git fetch" stores a new remote-tracking ref says "we know
there is no 'old' thing pointed at by the ref, as we are creating
it anew" by passing 0{40} for the 'old' side), and expect that a
codepath to locate an in-core object to return NULL as a sign that
the object does not exist. A look-up for an object that does not
exist however is quite costly with a repository with large number
of packfiles. This access pattern has been optimized.

Replace use of strbuf_addf() with strbuf_add() when enumerating
loose objects in for_each_file_in_obj_subdir(). Since we already
check the length and hex-values of the string before consuming
the path, we can prevent extra computation by using the lower-
level method.
One consumer of for_each_file_in_obj_subdir() is the abbreviation
code. OID abbreviations use a cached list of loose objects (per
object subdirectory) to make repeated queries fast, but there is
significant cache load time when there are many loose objects.
Most repositories do not have many loose objects before repacking,
but in the GVFS case the repos can grow to have millions of loose
objects. Profiling 'git log' performance in GitForWindows on a
GVFS-enabled repo with ~2.5 million loose objects revealed 12% of
the CPU time was spent in strbuf_addf().
Add a new performance test to p4211-line-log.sh that is more
sensitive to this cache-loading. By limiting to 1000 commits, we
more closely resemble user wait time when reading history into a
pager.
For a copy of the Linux repo with two ~512 MB packfiles and ~572K
loose objects, running 'git log --oneline --parents --raw -1000'
had the following performance:

In theory nobody should ever ask the low-level object code
for a null sha1. It's used as a sentinel for "no such
object" in lots of places, so leaking through to this level
is a sign that the higher-level code is not being careful
about its error-checking. In practice, though, quite a few
code paths seem to rely on the null sha1 lookup failing as a
way to quietly propagate non-existence (e.g., by feeding it
to lookup_commit_reference_gently(), which then returns
NULL).
When this happens, we do two inefficient things:
1. We actually search for the null sha1 in packs and in
the loose object directory.
2. When we fail to find it, we re-scan the pack directory
in case a simultaneous repack happened to move it from
loose to packed. This can be very expensive if you have
a large number of packs.
Only the second one actually causes noticeable performance
problems, so we could treat them independently. But for the
sake of simplicity (both of code and of reasoning about it),
it makes sense to just declare that the null sha1 cannot be
a real on-disk object, and looking it up will always return
"no such object".
There's no real loss of functionality to do so Its use as a
sentinel value means that anybody who is unlucky enough to
hit the 2^-160th chance of generating an object with that
sha1 is already going to find the object largely unusable.
In an ideal world, we'd simply fix all of the callers to
notice the null sha1 and avoid passing it to us. But a
simple experiment to catch this with a BUG() shows that
there are a large number of code paths that do so.
So in the meantime, let's fix the performance problem by
taking a fast exit from the object lookup when we see a null
sha1. p5551 shows off the improvement (when a fetched ref is
new, the "old" sha1 is 0{40}, which ends up being passed for
fast-forward checks, the status table abbreviations, etc):

Make it safer to normalize the line endings in a repository.
Files that had been commited with CRLF will be commited with LF.
The old way to normalize a repo was like this:
# Make sure that there are not untracked files
$ echo "* text=auto" >.gitattributes
$ git read-tree --empty
$ git add .
$ git commit -m "Introduce end-of-line normalization"
The user must make sure that there are no untracked files,
otherwise they would have been added and tracked from now on.
The new "add --renormalize" does not add untracked files:
$ echo "* text=auto" >.gitattributes
$ git add --renormalize .
$ git commit -m "Introduce end-of-line normalization"
Note that "git add --renormalize <pathspec>" is the short form for
"git add -u --renormalize <pathspec>".
While at it, document that the same renormalization may be needed,
whenever a clean filter is added or changed.

We used to add an empty alternate object database to the system
that does not help anything; it has been corrected.
* jk/info-alternates-fix:
link_alt_odb_entries: make empty input a noop
|
|
If an empty string is passed to link_alt_odb_entries(), our
loop finds no entries and we link nothing. But we still do
some preparatory work to normalize the object directory
path, even though we'll never look at the result. This
triggers in basically every git process, since we feed the
usually-empty ALTERNATE_DB_ENVIRONMENT to the function.
Let's detect early that there's nothing to do and return.
While we're at it, let's treat NULL the same as an empty
string as a favor to our callers. That saves
prepare_alt_odb() from having to cover this case.

Since in the future we want to support an additional hash algorithm, add
a structure that represents a hash algorithm and all the data that must
go along with it. Add a constant to allow easy enumeration of hash
algorithms. Implement function typedefs to create an abstract API that
can be used by any hash algorithm, and wrappers for the existing SHA1
functions that conform to this API.
Expose a value for hex size as well as binary size. While one will
always be twice the other, the two values are both used extremely
commonly throughout the codebase and providing both leads to improved
readability.
Don't include an entry in the hash algorithm structure for the null
object ID. As this value is all zeros, any suitably sized all-zero
object ID can be used, and there's no need to store a given one on a
per-hash basis.
The current hash function transition plan envisions a time when we will
accept input from the user that might be in SHA-1 or in the NewHash
format. Since we cannot know which the user has provided, add a
constant representing the unknown algorithm to allow us to indicate that
we must look the correct value up. Provide dummy API functions that die
in this case.
Finally, include git-compat-util.h in hash.h so that the required types
are available. This aids people using automated tools their editors.

The path of a loose object contains its hash value encoded into two
substrings of 2 and 38 hexadecimal digits separated by a slash. The
first part is handed to for_each_file_in_obj_subdir() in decoded form as
subdir_nr. The current code builds a full hexadecimal representation of
the hash in a temporary buffer, then uses get_oid_hex() to decode it.
Avoid the intermediate step by taking subdir_nr as-is and using
hex_to_bytes() directly on the second substring. That's shorter and
easier.

Leakfix and futureproofing.
* jk/sha1-loose-object-info-fix:
sha1_loose_object_info: handle errors from unpack_sha1_rest
|
|
When a caller of sha1_object_info_extended() sets the
"contentp" field in object_info, we call unpack_sha1_rest()
but do not check whether it signaled an error.
This causes two problems:
1. We pass back NULL to the caller via the contentp field,
but the function returns "0" for success. A caller
might reasonably expect after a successful return that
it can access contentp without a NULL check and
segfault.
As it happens, this is impossible to trigger in the
current code. There is exactly one caller which uses
contentp, read_object(). And the only thing it does
after a successful call is to return the content
pointer to its caller, using NULL as a sentinel for
errors. So in effect it converts the success code from
sha1_object_info_extended() back into an error!
But this is still worth addressing avoid problems for
future users of "contentp".
2. Callers of unpack_sha1_rest() are expected to close the
zlib stream themselves on error. Which means that we're
leaking the stream.
The problem in (1) comes from from c84a1f3ed4 (sha1_file:
refactor read_object, 2017-06-21), which added the contentp
field. Before that, we called unpack_sha1_rest() via
unpack_sha1_file(), which directly used the NULL to signal
an error.
But note that the leak in (2) is actually older than that.
The original unpack_sha1_file() directly returned the result
of unpack_sha1_rest() to its caller, when it should have
been closing the zlib stream itself on error.

There is no longer any need to allocate and leak a `struct lock_file`.
Initialize it on the stack instead.
Before this patch, we set `lock = NULL` to signal that we have already
rolled back, and that we should not do any more work. We need to take
another approach now that we cannot assign NULL. We could, e.g., use
`is_lock_file_locked()`. But we already have another variable that we
could use instead, `found`. Its scope is only too small.
Bump `found` to the scope of the whole function and rearrange the "roll
back or write?"-checks to a straightforward if-else on `found`. This
also future-proves the code by making it obvious that we intend to take
exactly one of these paths.

When a caller tries to read a particular set of bytes via
read_in_full(), there are three possible outcomes:
1. An error, in which case -1 is returned and errno is
set.
2. A short read, in which fewer bytes are returned and
errno is unspecified (we never saw a read error, so we
may have some random value from whatever syscall failed
last).
3. The full read completed successfully.
Many callers handle cases 1 and 2 together by just checking
the result against the requested size. If their combined
error path looks at errno (e.g., by calling die_errno), they
may report a nonsense value.
Let's fix these sites by having them distinguish between the
two error cases. That avoids the random errno confusion, and
lets us give more detailed error messages.

When we fail to open $GIT_DIR/info/alternates, we silently
assume there are no alternates. This is the right thing to
do for ENOENT, but not for other errors.
A hard error is probably overkill here. If we fail to read
an alternates file then either we'll complete our operation
anyway, or we'll fail to find some needed object. Either
way, a warning is good idea. And we already have a helper
function to handle this pattern; let's just call
warn_on_fopen_error().
Note that technically the errno from strbuf_read_file()
might be from a read() error, not open(). But since read()
would never return ENOENT or ENOTDIR, and since it produces
a generic "unable to access" error, it's suitable for
handling errors from either.

* jk/info-alternates-fix-2.11:
read_info_alternates: read contents into strbuf
|
|
This patch fixes a regression in v2.11.1 where we might read
past the end of an mmap'd buffer. It was introduced in
cf3c635210.
The link_alt_odb_entries() function has always taken a
ptr/len pair as input. Until cf3c635210 (alternates: accept
double-quoted paths, 2016-12-12), we made a copy of those
bytes in a string. But after that commit, we switched to
parsing the input left-to-right, and we ignore "len"
totally, instead reading until we hit a NUL.
This has mostly gone unnoticed for a few reasons:
1. All but one caller passes a NUL-terminated string, with
"len" pointing to the NUL.
2. The remaining caller, read_info_alternates(), passes in
an mmap'd file. Unless the file is an exact multiple of
the page size, it will generally be followed by NUL
padding to the end of the page, which just works.
The easiest way to demonstrate the problem is to build with:
make SANITIZE=address NO_MMAP=Nope test
Any test which involves $GIT_DIR/info/alternates will fail,
as the mmap emulation (correctly) does not add an extra NUL,
and ASAN complains about reading past the end of the buffer.
One solution would be to teach link_alt_odb_entries() to
respect "len". But it's actually a bit tricky, since we
depend on unquote_c_style() under the hood, and it has no
ptr/len variant.
We could also just make a NUL-terminated copy of the input
bytes and operate on that. But since all but one caller
already is passing a string, instead let's just fix that
caller to provide NUL-terminated input in the first place,
by swapping out mmap for strbuf_read_file().
There's no advantage to using mmap on the alternates file.
It's not expected to be large (and anyway, we're copying its
contents into an in-memory linked list). Nor is using
git_open() buying us anything here, since we don't keep the
descriptor open for a long period of time.
Let's also drop the "len" parameter entirely from
link_alt_odb_entries(), since it's completely ignored. That
will avoid any new callers re-introducing a similar bug.

The result of read_in_full() may be -1 if we saw an error.
But in comparing it to a sizeof() result, that "-1" will be
promoted to size_t. In fact, the largest possible size_t
which is much bigger than our struct size. This means that
our "< sizeof(header)" error check won't trigger.
In practice, we'd go on to read uninitialized memory and
compare it to the PACK signature, which is likely to fail.
But we shouldn't get there.
We can fix this by making a direct "!=" comparison to the
requested size, rather than "<". This means that errors get
lumped in with short reads, but that's sufficient for our
purposes here. There's no PH_ERROR tp represent our case.
And anyway, this function reads from pipes and network
sockets. A network error may racily appear as EOF to us
anyway if there's data left in the socket buffers.

Both sha1_file.c and packfile.c now need read_object(), so a copy of
read_object() was created in packfile.c.
This patch makes both mark_bad_packed_object() and has_packed_and_bad()
global. Unlike most of the other patches in this series, these 2
functions need to remain global.
