Even in a repository with promisor remote, it is useless to
attempt to lazily attempt fetching an object that is expected to be
commit, because no "filter" mode omits commit objects. Take
advantage of this assumption to fail fast on errors.
* jt/avoid-lazy-fetch-commits:
commit: don't lazy-fetch commits
object-file: emit corruption errors when detected
object-file: refactor map_loose_object_1()
object-file: remove OBJECT_INFO_IGNORE_LOOSE
|
|
Code clean-up.
* rs/clear-commit-marks-cleanup:
commit: skip already cleared parents in clear_commit_marks_1()
|
|
When parsing commits, fail fast when the commit is missing or
corrupt, instead of attempting to fetch them. This is done by inlining
repo_read_object_file() and setting the flag that prevents fetching.
This is motivated by a situation in which through a bug (not necessarily
through Git), there was corruption in the object store of a partial
clone. In this particular case, the problem was exposed when "git gc"
tried to expire reflogs, which calls repo_parse_commit(), which triggers
fetches of the missing commits.
(There are other possible solutions to this problem including passing an
argument from "git gc" to "git reflog" to inhibit all lazy fetches, but
I think that this fix is at the wrong level - fixing "git reflog" means
that this particular command works fine, or so we think (it will fail if
it somehow needs to read a legitimately missing blob, say, a .gitmodules
file), but fixing repo_parse_commit() will fix a whole class of bugs.)

"git rebase --keep-base" used to discard the commits that are
already cherry-picked to the upstream, even when "keep-base" meant
that the base, on top of which the history is being rebuilt, does
not yet include these cherry-picked commits. The --keep-base
option now implies --reapply-cherry-picks and --no-fork-point
options.
* pw/rebase-keep-base-fixes:

rebase: store orig_head as a commit
rebase: be stricter when reading state files containing oids
t3416: set $EDITOR in subshell

|
|
The state files for 'onto' and 'orig_head' should contain a full hex
oid, change the reading functions from get_oid() to get_oid_hex() to
reflect this. They should also name commits and not tags so add and use
a function that looks up a commit from an oid like
lookup_commit_reference() but without dereferencing tags.

As reported in [1] the "UNUSED(var)" macro introduced in
2174b8c75de (Merge branch 'jk/unused-annotation' into next,
2022-08-24) breaks coccinelle's parsing of our sources in files where
it occurs.
Let's instead partially go with the approach suggested in [2] of
making this not take an argument. As noted in [1] "coccinelle" will
ignore such tokens in argument lists that it doesn't know about, and
it's less of a surprise to syntax highlighters.
This undoes the "help us notice when a parameter marked as unused is
actually use" part of 9b240347543 (git-compat-util: add UNUSED macro,
2022-08-19), a subsequent commit will further tweak the macro to
implement a replacement for that functionality.

Some config variables are combinations of multiple words, and we
typically write them in camelCase forms in manpage and translatable
strings. It's not easy to find mismatches for these camelCase config
variables during code reviews, but occasionally they are identified
during localization translations.
To check for mismatched config variables, I introduced a new feature
in the helper program for localization[^1]. The following mismatched
config variables have been identified by running the helper program,
such as "git-po-helper check-pot".
Lowercase in manpage should use camelCase:
* Documentation/config/http.txt: http.pinnedpubkey
Lowercase in translable strings should use camelCase:
* builtin/fast-import.c: pack.indexversion
* builtin/gc.c: gc.logexpiry
* builtin/index-pack.c: pack.indexversion
* builtin/pack-objects.c: pack.indexversion
* builtin/repack.c: pack.writebitmaps
* commit.c: i18n.commitencoding
* gpg-interface.c: user.signingkey
* http.c: http.postbuffer
* submodule-config.c: submodule.fetchjobs
Mismatched camelCases, choose the former:
* Documentation/config/transfer.txt: transfer.credentialsInUrl
remote.c: transfer.credentialsInURL

When a commit is parsed, it pretends to have a different (possibly
empty) list of parents if there is graft information for that commit.
But there is a bug that could occur when a commit is parsed, the graft
information is updated (for example, when a shallow file is rewritten),
and the same commit is subsequently used: the parents of the commit do
not conform to the updated graft information, but the information at the
time of parsing.
This is usually not an issue, as a commit is usually introduced into the
repository at the same time as its graft information. That means that
when we try to parse that commit, we already have its graft information.
But it is an issue when fetching a shallow point directly into a
repository with submodules. The function
assign_shallow_commits_to_refs() parses all sought objects (including
the shallow point, which we are directly fetching). In update_shallow()
in fetch-pack.c, assign_shallow_commits_to_refs() is called before
commit_shallow_file(), which means that the shallow point would have
been parsed before graft information is updated. Once a commit is
parsed, it is no longer sensitive to any graft information updates. This
parsed commit is subsequently used when we do a revision walk to search
for submodules to fetch, meaning that the commit is considered to have
parents even though it is a shallow point (and therefore should be
treated as having no parents).
Therefore, whenever graft information is updated, mark the commits that
were previously grafts and the commits that are newly grafts as
unparsed.

patch -p1 <contrib/coccinelle/free.cocci.patch

Regression fix.
* ab/racy-hooks:
hooks: fix "invoked hook" regression in a8cc5943338
|
|
Fix a regression in a8cc5943338 (hooks: fix an obscure TOCTOU "did we
just run a hook?" race, 2022-03-07): The "invoked_hook" variable
passed to run_commit_hook() wasn't passed forward to run_hooks_opt(),
as push_to_checkout() in that commit correctly did.
Whether we ran the code contingent on having run the hook or not was
thus undefined, but in practice on most (all?) modern platforms we'd
have run it (almost?) all the time, since stack variables will get
initialized to some random value, which most of the time isn't "0".
This bug was revealed by running e.g. "t5537-fetch-shallow.sh" with
the --valgrind option. Unfortunately running the whole test suite with
--valgrind is really slow, so we didn't have a CI job that spotted
this. The --valgrind output was:
==31275== Conditional jump or move depends on uninitialised value(s)
==31275== at 0x43C63F: prepare_to_commit (commit.c:1058)

When reset_repository_shallow() is called, Git clears its cache of
shallow information, so that if shallow information is re-requested, Git
will read fresh data from disk instead of reusing its stale cached data.
However, the cache of commit grafts is not likewise cleared, even though
there are commit grafts created from shallow information.
This means that if on-disk shallow information were to be updated and
then a commit-graft-using codepath were run (for example, a revision
walk), Git would be using stale commit graft information. This can be
seen from the test in this patch, in which Git performs a revision walk
(to check for changed submodules) after a fetch with --update-shallow.
Therefore, clear the cache of commit grafts whenever
reset_repository_shallow() is called.

Fix a Time-of-check to time-of-use (TOCTOU) race in code added in
680ee550d72 (commit: skip discarding the index if there is no
pre-commit hook, 2017-08-14).
This obscure race condition can occur if we e.g. ran the "pre-commit"
hook and it modified the index, but hook_exists() returns false later
on (e.g., because the hook itself went away, the directory became
unreadable, etc.). Then we won't call discard_cache() when we should
have.
The race condition itself probably doesn't matter, and users would
have been unlikely to run into it in practice. This problem has been
noted on-list when 680ee550d72 was discussed[1], but had not been
fixed.
This change is mainly intended to improve the readability of the code
involved, and to make reasoning about it more straightforward. It
wasn't as obvious what we were trying to do here, but by having an
"invoked_hook" it's clearer that e.g. our discard_cache() is happening
because of the earlier hook execution.
Let's also change this for the push-to-checkout hook. Now instead of
checking if the hook exists and either doing a push to checkout or a
push to deploy we'll always attempt a push to checkout. If the hook
doesn't exist we'll fall back on push to deploy. The same behavior as
before, without the TOCTOU race. See 0855331941b (receive-pack:
support push-to-checkout hook, 2014-12-01) for the introduction of the
previous behavior.
This leaves uses of hook_exists() in two places that matter. The
"reference-transaction" check in refs.c, see 67541597670 (refs:
implement reference transaction hook, 2020-06-19), and the
"prepare-commit-msg" hook, see 66618a50f9c (sequencer: run
'prepare-commit-msg' hook, 2018-01-24).
In both of those cases we're saving ourselves CPU time by not
preparing data for the hook that we'll then do nothing with if we
don't have the hook. So using this "invoked_hook" pattern doesn't make
sense in those cases.
The "reference-transaction" and "prepare-commit-msg" hook also aren't
racy. In those cases we'll skip the hook runs if we race with a new
hook being added, whereas in the TOCTOU races being fixed here we were
incorrectly skipping the required post-hook logic.

Change the write_object_file() function to take an "enum object_type"
instead of a "const char *type". Its callers either passed
{commit,tree,blob,tag}_type and can pass the corresponding OBJ_* type
instead, or were hardcoding strings like "blob".
This avoids the back & forth fragility where the callers of
write_object_file() would have the enum type, and convert it
themselves via type_name(). We do have to now do that conversion
ourselves before calling write_object_file_prepare(), but those
codepaths will be similarly adjusted in subsequent commits.

There are two functions that have very similar logic of finding a header
value. find_commit_header, and find_header. We can conslidate the logic
by introducing a new function find_header_mem, which is equivalent to
find_commit_header except it takes a len parameter that determines how
many bytes will be read. find_commit_header and find_header can then both
call find_header_mem.
This reduces duplicate logic, as the logic for finding header values
can now all live in one place.

If valid-before/after dates are configured for this signatures key in the
allowedSigners file then the verification should check if the key was valid at
the time the commit was made. This allows for graceful key rollover and
revoking keys without invalidating all previous commits.
This feature needs openssh > 8.8. Older ssh-keygen versions will simply
ignore this flag and use the current time.
Strictly speaking this feature is available in 8.7, but since 8.7 has a
bug that makes it unusable in another needed call we require 8.8.
Timestamp information is present on most invocations of check_signature.
However signer ident is not. We will need the signer email / name to be able
to implement "Trust on first use" functionality later.
Since the payload contains all necessary information we can parse it
from there. The caller only needs to provide us some info about the
payload by setting payload_type in the signature_check struct.
- Add payload_type field & enum and payload_timestamp to struct
signature_check
- Populate the timestamp when not already set if we know about the
payload type
- Pass -Overify-time={payload_timestamp} in the users timezone to all
ssh-keygen verification calls
- Set the payload type when verifying commits
- Add tests for expired, not yet valid and keys having a commit date
outside of key validity as well as within

To be able to extend the payload metadata with things like its creation
timestamp or the creators ident we remove the payload parameters to
check_signature() and use the already existing sigc->payload field
instead, only adding the length field to the struct. This also allows
us to get rid of the xmemdupz() calls in the verify functions. Since
sigc is now used to input data as well as output the result move it to
the front of the function list.
- Add payload_length to struct signature_check
- Populate sigc.payload/payload_len on all call sites
- Remove payload parameters to check_signature()
- Remove payload parameters to internal verify_* functions and use sigc
instead
- Remove xmemdupz() used for verbose output since payload is now already
populated.

We generally avoid specifying the gender of our users in order to be
more inclusive, but sometimes a few slip by due to habit.
Since by doing a little bit of rewording we can avoid this irrelevant
detail, let's do so.

"git commit --fixup=<commit>", which was to tweak the changes made
to the contents while keeping the original log message intact,
learned "--fixup=(amend|reword):<commit>", that can be used to
tweak both the message and the contents, and only the message,
respectively.

This function can be used in other parts of git. Let's move the
function to commit.c and also rename it to make the name of the
function more generic.

Add and apply a semantic patch for converting code that open-codes
CALLOC_ARRAY to use it instead. It shortens the code and infers the
element size automatically.

Signed commits and tags now allow verification of objects, whose
two object names (one in SHA-1, the other in SHA-256) are both
signed.
* bc/signed-objects-with-both-hashes:
gpg-interface: remove other signature headers before verifying
ref-filter: hoist signature parsing
commit: allow parsing arbitrary buffers with headers
gpg-interface: improve interface for parsing tags
commit: ignore additional signatures when parsing signed commits
ref-filter: switch some uses of unsigned long to size_t

The commit-graph learned to use corrected commit dates instead of
the generation number to help topological revision traversal.
* ak/corrected-commit-date:
doc: add corrected commit date info
commit-reach: use corrected commit dates in paint_down_to_common()
commit-graph: use generation v2 only if entire chain does
commit-graph: implement generation data chunk
commit-graph: implement corrected commit date
commit-graph: return 64-bit generation number
commit-graph: add a slab to store topological levels
t6600-test-reach: generalize *_three_modes
commit-graph: consolidate fill_commit_graph_info
revision: parse parent in indegree_walk_step()
commit-graph: fix regression when computing Bloom filters

Currently only commits are signed with headers. However, in the future,
we'll also sign tags with headers as well. Let's refactor out a
function called parse_buffer_signed_by_header which does exactly that.
In addition, since we'll want to sign things other than commits this
way, let's call the function sign_with_header instead of do_sign_commit.

We have a function which parses a buffer with a signature at the end,
parse_signature, and this function is used for signed tags. However,
we'll need to store values for multiple algorithms, and we'll do this by
using a header for the non-default algorithm.
Adjust the parse_signature interface to store the parsed data in two
strbufs and turn the existing function into parse_signed_buffer. The
latter is still used in places where we know we always have a signed
buffer, such as push certs.
Adjust all the callers to deal with this new interface.

When we are looking up an oid in an array, we obviously don't need to
write to the array. Let's mark it as const in the function interfaces,
as well as in the local variables we use to derference the void pointer
(note a few cases use pointers-to-pointers, so we mark everything
const).

All of our callers are actually looking up an object_id, not a bare
hash. Likewise, the arrays they are looking in are actual arrays of
object_id (not just raw bytes of hashes, as we might find in a pack
.idx; those are handled by bsearch_hash()).
Using an object_id gives us more type safety, and makes the callers
slightly shorter. It also gets rid of the word "sha1" from several
access functions, though we could obviously also rename those with
s/sha1/hash/.

All of our callers have an object_id, and are just dereferencing the
hash field to pass to us. Let's take the actual object_id instead. We
still access the hash to pass to hash_pos, but it's a step in the right
direction.
This makes the callers slightly simpler, but also gets rid of the
untyped pointer, as well as the now-inaccurate name "sha1".
