Error messages should be sentence fragments, and therefore:
1. Should not begin with a capital letter,
2. Should not conclude with punctuation, and
3. Should not end a sentence and begin a new one
When checking for out of memory situations we usually use the
GITERR_CHECK_ALLOC macro. Besides conforming to our current code
base it adds the benefit of silencing errors in Coverity due to
Coverity handling the macro's error path as abort.
A signature is made up of a non-empty name and a non-empty email so
let's validate that. This also brings us more in line with git, which
also rejects ident with an empty email.
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 changes git_signature_dup to actually honor oom conditions raised by
the call to git__strdup. It also aligns it with the error code return
pattern used everywhere else.
There are all sorts of misconfiguration in the wild. We already rely
on the signature constructor to trim SP. Extend the logic to use
`isspace` to decide whether a character should be trimmed.
This is a significant reorganization of the diff code to break it
into a set of more clearly distinct files and to document the new
organization. Hopefully this will make the diff code easier to
understand and to extend.
This adds a new `git_diff_driver` object that looks of diff driver
information from the attributes and the config so that things like
function content in diff headers can be provided. The full driver
spec is not implemented in the commit - this is focused on the
reorganization of the code and putting the driver hooks in place.
This also removes a few #includes from src/repository.h that were
overbroad, but as a result required extra #includes in a variety
of places since including src/repository.h no longer results in
pulling in the whole world.
git doesn't do that, and it's not something that's usually
actionable to fix. if you have a git repository with one bad
timezone in the history, it's too late to change it most likely.
The commit time is already stored as a git_time_t, but we were
parsing is as a uint32_t. This just switches the parser to use
uint64_t which will handle dates further in the future (and adds
some tests of those future dates).
There is a better and less fragile way to calculate time offsets. Let
the OS take care of dealing with DST and simply take the the offset
between the local time and UTC that it gives us.
Ported the win32 implementations of gmtime_r,
localtime_r, and gettimeofday to be part of the
posix compatibility layer, and fixed
git_signature_now to use them.
This converts virtually all of the places that allocate GIT_PATH_MAX
buffers on the stack for manipulating paths to use git_buf objects
instead. The patch is pretty careful not to touch the public API
for libgit2, so there are a few places that still use GIT_PATH_MAX.
This extends and changes some details of the git_buf implementation
to add a couple of extra functions and to make error handling easier.
This includes serious alterations to all the path.c functions, and
several of the fileops.c ones, too. Also, there are a number of new
functions that parallel existing ones except that use a git_buf
instead of a stack-based buffer (such as git_config_find_global_r
that exists alongsize git_config_find_global).
This also modifies the win32 version of p_realpath to allocate whatever
buffer size is needed to accommodate the realpath instead of hardcoding
a GIT_PATH_MAX limit, but that change needs to be tested still.
When trying to find the end of an email, instead of starting at the
beginning of the signature, we start at the end of the name (after the
first '<').
This brings libgit2 more in line with Git's behavior when reading out
existing signatures.
However, note that Git does not allow names like these through the
usual porcelain; instead, it silently strips any '>' characters it
sees.
1. The license header is technically not valid if it doesn't have a
copyright signature.
2. The COPYING file has been updated with the different licenses used in
the project.
3. The full GPLv2 header in each file annoys me.
git_signature_new() and git_signature_now() currently don't return error
codes. Change the API to return error codes and not pointers to let the
user handle errors properly.

The direct-writes commit left some (slow) internals methods that
were no longer needed. These have been removed.
Also, the Reflog code was using the old `git_signature__write`, so
it has been rewritten to use a normal buffer and the new `writebuf`
signature writer. It's now slightly simpler and faster.
