The section and variable names use different rules, so store them as
two different variables internally.

This will simplify the configuration-writing code as well later on,
but even with parsing, the code is simpler.

Take this opportunity to add a variable to the list directly when
parsing instead of passing through config_set.

Obviously, the whole string should be lower-cased and not just the
last char.

Allow a number not to have a suffix. This broke when adding the
suffixes.

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.

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

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

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.

long int is a safer type than int unless the user knows that the

The code has been reworked to use strtol instead of the more

Many error paths freed their local data althought it is freed later on
when the end of the function notices that there was an error. This can
cause double frees and invalid memory access.

Make cvar_free return void instad of the next element, as it was
mostly a hack to make cvar_list_free shorter but it's now using the
list macros.

Also check if the input is NULL and return immediately in that case.

Use list macros instead of manually changing the head and/or tail of
the variable list.

Due to the preconditions, there should never be an error, but it pays
to be paranoid.
