Introduce a new binary diff callback to provide the actual binary
delta contents to callers. Create this data from the diff contents
(instead of directly from the ODB) to support binary diffs including
the workdir, not just things coming out of the ODB.
These tests were not being taken into consideration for the failure of
the test. They've been failing for a while now, but we hadn't noticed as
Travis was reporting the builds successful.
The read and write callbacks passed to SSLSetIOFuncs() have been
rewritten to match the implementation used on opensource.apple.com and
other open source projects like VLC.
This change also fixes a bug where the read callback could get into
an infinite loop when 0 bytes were read.
Some tools create multiple author fields. git is rather lax when parsing
them, although fsck does complain about them. This means that they exist
in the wild.
As it's not too taxing to check for them, and there shouldn't be a
noticeable slowdown when dealing with correct commits, add logic to skip
over these extra fields when parsing the commit.
When we hit an error writing to the next stream from a file, we jump to
'done' which currently skips over closing the file descriptor.
Make sure to close the descriptor if it has been set to a valid value.
We take in a possibly partial ID by taking a length and working off of
that to figure out whether to just look up the object or ask the
backends for a prefix lookup.
Unfortunately we've been checking the size against `GIT_OID_HEXSZ` which
is the size of a *string* containing a full ID, whereas we need to check
against the size we can have when it's a 20-byte array.
Change the checks and comment to use `GIT_OID_RAWSZ` which is the
correct size of a git_oid to have when full.
The way we currently do it depends on the subtlety of strlen vs sizeof
and the fact that .pack is one longer than .idx. Let's use a git_buf so
we can express the manipulation we want much more clearly.
`merge_diff_list_count_candidates()` takes pointers to the source and
target counts, but when it comes time to increase them, we're increasing
the pointer, rather than the value it's pointing to.
Dereference the value to increase.
Coverity complains about the git_rawobj ones because we use a loop in
which we keep remembering the old version, and we end up copying our
object as the base, so we want to have the data pointer be NULL.
Let `ssh_stream_free()` take a NULL stream, as free functions should,
and remove the check from the connection setup.
The connection setup would not need the check anyhow, as we always have
a stream by the time we reach this code.
When the callback returns an error, we should stop immediately. This
broke when trying to make sure we pass specific errors up the chain.
This broke cancelling out of the loose backend's foreach.
