Building a "shared object" (DLL) in Windows includes 2 steps:
- specify __declspec(dllexport)
when building the library itself. MSVC will disallow itself from
optimizing these symbols out and reference them in the PE's
Exports-Table.
Further, a static link library will be generated. This library
contains the symbols which are exported via the declsepc above.
The __declspec(dllexport) becomes part of the symbol-signature
(like parameter types in C++ are 'mangled' into the symbol name,
the export specifier is mingled with the name)
- specify __declspec(dllimport)
when using the library. This again mingles the declspec into the
name and declares the function / variable with external linkage.
cmake automatically adds -Dgit2_EXPORTS to the compiler arguments
when compiling the libgit2 project.
The 'git2' is the name specified via PROJECT() in CMakeLists.txt.
This makes the git attributes and git ignores cache check
stat information before using the file contents from the
cache. For cached files from the index, it checks the SHA
of the file instead. This should reduce the need to ever
call `git_attr_cache_flush()` in most situations.
This commit also fixes the `git_status_should_ignore` API
to use the libgit2 standard parameter ordering.
'git commit' and 'git tag -a' enforce some conventions, like cleaning up excess whitespace and making sure that the last line ends with a '\n'. This fix replicates this behavior.

Depending on the operation, we need to consider gitattributes
in both the work dir and the index. This adds a parameter to
all of the gitattributes related functions that allows user
control of attribute reading behavior (i.e. prefer workdir,
prefer index, only use index).
This fix also covers allowing us to check attributes (and
hence do diff and status) on bare repositories.
This was a somewhat larger change that I hoped because it had
to change the cache key used for gitattributes files.
This allows the caller to update an internal structure or update the
user output with the tips that were updated.
While in the area, only try to update the ref if the value is
different from its old one.
Trying to send every single line immediately won't give us any speed
improvement and duplicates the code we need for other transports. Make
the git transport use the same buffer functions as HTTP.
This changes the git_remote_download() API, but the existing one is
silly, so you don't get to complain.
The new API allows to know how much data has been downloaded, how many
objects we expect in total and how many we've processed.
Adds a new public reference function `git_reference_lookup_oid`
that directly resolved a reference name to an OID without returning
the intermediate `git_reference` object (hence, no free needed).
Internally, this adds a `git_reference_lookup_resolved` function
that combines looking up and resolving a reference. This allows
us to be more efficient with memory reallocation.
The existing `git_reference_lookup` and `git_reference_resolve`
are reimplmented on top of the new utility and a few places in the
code are changed to use one of the two new functions.
This adds preliminary support for pathspecs to diff and status.
The implementation is not very optimized (it still looks at
every single file and evaluated the the pathspec match against
them), but it works.
This will allow us to index a packfile as soon as we receive it from
the network as well as storing it with its final name so we don't need
to pass temporary file names around.
It's implemented in revwalk.c so it has access to the revision
walker's commit cache and related functions. The algorithm is the one
used by git, modified so it fits better with the library's functions.
The code was already there, so factor it out and let users push an OID
by giving it a reference name. Only refs to commits are
supported. Annotated tags will throw an error.
Add a new command `git_repository_open_ext` with extended options
that control how searching for a repository will be done. The
existing `git_repository_open` and `git_repository_discover` are
reimplemented on top of it. We may want to change the default
behavior of `git_repository_open` but this commit does not do that.
Improve support for "gitdir" files where the work dir is separate
from the repo and support for the "separate-git-dir" config. Also,
add support for opening repos created with `git-new-workdir` script
(although I have only confirmed that they can be opened, not that
all functions work correctly).
There are also a few minor changes that came up:
- Fix `git_path_prettify` to allow in-place prettifying.
- Fix `git_path_root` to support backslashes on Win32. This fix
should help many repo open/discover scenarios - it is the one
function called when opening before prettifying the path.
- Tweak `git_config_get_string` to set the "out" pointer to NULL
if the config value is not found. Allows some other cleanup.
- Fix a couple places that should have been calling
`git_repository_config__weakptr` and were not.
- Fix `cl_git_sandbox_init` clar helper to support bare repos.
