credential: handle `credential.<partial-URL>.<key>` again

In the patches for CVE-2020-11008, the ability to specify credential
settings in the config for partial URLs got lost. For example, it used
to be possible to specify a credential helper for a specific protocol:

[credential "https://"]
helper = my-https-helper

Likewise, it used to be possible to configure settings for a specific
host, e.g.:

[credential "dev.azure.com"]
useHTTPPath = true

Let's reinstate this behavior.

While at it, increase the test coverage to document and verify the
behavior with a couple other categories of partial URLs.

Replace plain struct definitions of OPTION_CALLBACK with OPT_CALLBACK or

following (disgusting) shell script:

#!/bin/sh

received_ack is meant to track that an ACK was received, but it was

urlmatch.  In doing so, it introduced code to percent-encode the paths
we get from the credential helper so that they could be effectively
matched by the urlmatch code.

Unfortunately, that code had a bug: it percent-encoded the slashes in
the path, resulting in any URL path that contained multiple levels
(i.e., a directory component) not matching.

We are currently the only caller of the percent-encoding code and could
simply change it not to encode slashes.  However, we still want to
encode slashes in the username component, so we need to have both
behaviors available.

So instead, let's add a flag to control encoding slashes, which is the
behavior we want here, and use it when calling the code in this case.

Add a test for credential helper URLs using multiple slashes in the
path, which our test suite previously lacked, as well as one ensuring
that we handle usernames with slashes gracefully.  Since we're testing

Sometimes the ci job succeeds:
 brew link --force gettext

(And the is not the final word either, since macOS itself says:
 The default interactive shell is now zsh.)

Anyway, The latter requires CFLAGS to include /usr/local/opt/gettext/include
and LDFLAGS to include /usr/local/opt/gettext/lib.

Likewise, the `msgfmt` tool is no longer in the `PATH`.

most notably only occurs on CI build agents that updated very recently),
https://github.com/Homebrew/homebrew-core/pull/53489 has fixed it.

Nevertheless, let's work around this issue, as there are still quite a
few build agents out there that need some help in this regard: we

We use 'hold_lock_file_for_update' (and the '_timeout') variant to
acquire a lock when updating references, the commit-graph file, and so
on.

In particular, the commit-graph machinery uses this to acquire a
temporary file that is used to write a non-split commit-graph. In a
subsequent commit, an issue in the commit-graph machinery produces
graph files that have a different permission based on whether or not
they are part of a multi-layer graph will be addressed.

To do so, the commit-graph machinery will need a version of
'hold_lock_file_for_update' that takes the permission bits from the
caller.

Introduce such a function in this patch for both the
'hold_lock_file_for_update' and 'hold_lock_file_for_update_timeout'
functions, and leave the existing functions alone by inlining their
definitions in terms of the new mode variants.

Note that, like in the previous commit, 'hold_lock_file_for_update_mode'
is not guarenteed to set the given mode, since it may be modified by
both the umask and 'core.sharedRepository'.

Note also that even though the commit-graph machinery only calls
'hold_lock_file_for_update', that this is defined in terms of
'hold_lock_file_for_update_timeout', and so both need an additional mode

In the next patch, 'hold_lock_file_for_update' will gain an additional

file.

Since the lockfile.c machinery uses 'create_tempfile' which always
creates a temporary file with global read-write permissions, introduce a
variant here that allows specifying the mode.

Note that the mode given to 'create_tempfile_mode' is not guaranteed to
be written to disk, since it is subject to both the umask and
'core.sharedRepository'.

Arguably, all temporary files should have permission 0444, since they
are likely to be renamed into place and then not written to again. This
is a much larger change than we may want to take on in this otherwise
small patch, so for the time being, make 'create_tempfile' behave as it

4 years agoshallow.c: use '{commit,rollback}_shallow_file'
Taylor Blau [Thu, 23 Apr 2020 00:25:45 +0000 (18:25 -0600)] 
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.

4 years agocommit-graph.c: gracefully handle file descriptor exhaustion
Taylor Blau [Thu, 23 Apr 2020 21:41:09 +0000 (15:41 -0600)] 
commit-graph.c: gracefully handle file descriptor exhaustion

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.
