Lists all the tag references in a repository using a custom callback.

They were backtracking too deep into the filesystem on Linux, where the
tests were running directly on `tmp/`.

This is what Git uses by default for all deflating.

The new name is more cool.

Most tags will have a timestamp of whenever the code is running and
dealing with time and timezones is error-prone. Optimize for this case
by adding a function which causes the signature to be created with a
current timestamp.

The parameters are given by '@param name' and not '@name'.

Add checks to see if malloc failed when allocating the tag members and
signature members.

git_repository_path() and git_repository_workdir() respectively return the path to the git repository and the working directory. Those paths are absolute and normalized.

We are now using a custom `strtol` implementation to make sure we're not
missing any overflow errors.

Weak tags (e.g. tags that point directly to a normal object instead of a
tag object) were failing to be packed.

Remove the check in git_tag_create_frombuffer as it's done by
tag_create already.

These indicate an inconsistency in the repository which we've created,
so don't allow them.

Don't blindly pass the target type to git_tag_type2string as it will
give an empty string on GIT_OBJ_ANY which would cause us to create an
invalid tag object.

Add several IDXENTRY flags that need to be checked in
order to properly implement update-index --refresh.

couldn't add new entry when inserting new one with `git_treebuilder_insert`.

We cannot assume that Redis is never going to return an error code; when
Reddit fails, we cannot crash our library, we need to handle the crash
gracefully.

The git test repository was holding a wrongly named tag reference ("very-simple") pointing at a tag named "e90810b".
This mistake (mine :-/ ) originates back to https://github.com/libgit2/libgit2/commit/9282e92

Whole credit goes to @tclem for having spotted this.

Streaming writes will no longer fail when writing to a backend that
doesn't support streaming writes but supports direct ones.
Now we create a fake stream on memory and then write it as a single
block using the backend `write` callback.

Creates a tree by scanning the index file. The method handles recursive
creation of trees for subdirectories and adds them to the parent tree.

To build libgit2 with sqlite support, waf configure should be run
with --with-sqlite

If we want debugging symbols, we most likely want them to point to the
right place. With -O2, gdb or valgrind may give wrong information.
