If a directory disappears between the time we look up the entries of its
parent and the time when we go to look at it, we should ignore the error
and move forward.
This fixes#2046.
This finds a short id string that will unambiguously select the
given object, starting with the core.abbrev length (usually 7)
and growing until it is no longer ambiguous.
A few fixes have accumulated in this area which have made the freeing of
data a bit muddy. Make sure to free the data only when needed and once.
When we are going to write a delta to the packfile, we need to free the
data, otherwise leave it. The current version of the code mixes up the
checks for po->data and po->delta_data.
This adds `git_diff_buffers` and `git_patch_from_buffers`. This
also includes a bunch of internal refactoring to increase the
shared code between these functions and the blob-to-blob and
blob-to-buffer APIs, as well as some higher level assert helpers
in the tests to also remove redundancy.
- added MSVC cmake definitions to disable warnings
- general.c is rewritten so it is ansi-c compatible and compiles ok on microsoft windows
- some MSVC reported warning fixes
* Make GIT_INLINE an internal definition so it cannot be used in
public headers
* Fix language in CONTRIBUTING
* Make index caps API use signed instead of unsigned values
On some systems, notably HP PA-RISC systems running Linux or HP-UX,
EWOULDBLOCK and EAGAIN are not the same value. POSIX (and these OSes) allow
EWOULDBLOCK to occur on write(2) (and send(2), etc.), so check explicitly
for this case as well as EAGAIN by defining and using a macro GIT_ISBLOCKED
that considers both.
The macro is necessary because MSYS does not provide EWOULDBLOCK and
compilation fails if an attempt is made to use it unconditionally. On most
systems, where the two values are the same, the compiler will simply
optimize this check out and it will have no effect.
This adds an API to amend an existing commit, basically a shorthand
for creating a new commit filling in missing parameters from the
values of an existing commit. As part of this, I also added a new
"sys" API to create a commit using a callback to get the parents.
This allowed me to rewrite all the other commit creation APIs so
that temporary allocations are no longer needed.
This fixes a number of warnings with the Windows 64-bit build
including a test failure in test_repo_message__message where an
invalid pointer to a git_buf was being used.
