In theory, if there was a problem reading the REUC data, the
read_reuc() routine could have left uninitialized and invalid
data in the git_index vector. This moves the line that inserts a
new entry into the vector down to the bottom of the routine so we
know all the content is already valid. Also, per @linquize, this
uses calloc to ensure no uninitialized data.
Since I added the GIT_IDXENTRY_STAGE macro to extract the stage
from a git_index_entry, we probably don't need an internal inline
function to do the same thing.
It is possible for there to be a submodule in a repository with
no .gitmodules file (for example, if the user forgot to commit
the .gitmodules file). In this case, core Git will just create
an empty directory as a placeholder for the submodule but
otherwise ignore it. We were generating an error and stopping
the checkout. This makes our behavior match that of core git.
This converts many of the config lookups that are done around the
library to use the repository config cache. This was everything I
could find that wasn't part of diff (which requires a larger fix).
Implicit type conversion argument of function to size_t type
Suspicious sequence of types castings: size_t -> int -> size_t
Consider reviewing the expression of the 'A = B == C' kind. The expression is calculated as following: 'A = (B == C)'
Unsigned type is never < 0
The iterator APIs are not currently consistent with the parameter
ordering of the rest of the codebase. This rearranges the order
of parameters, simplifies the naming of a number of functions, and
makes somewhat better use of macros internally to clean up the
iterator code.
This also expands the test coverage of iterator functionality,
making sure that case sensitive range-limited iteration works
correctly.
Instead of returning directly the pattern as the return value, I used an
out parameter, because the function also tests if the passed pathspecs
vector is empty. If yes, it considers that the path "matches", but in
that case there is no matched pattern per se.
This removes the need to explicitly pass the repo into iterators
where the repo is implied by the other parameters. This moves
the repo to be owned by the parent struct. Also, this has some
iterator related updates to the internal diff API to lay the
groundwork for checkout improvements.
This fixes some missed places where we can apply const-ness to
various public APIs.
There are still some index and tree APIs that cannot take const
pointers because we sort our `git_vectors` lazily and so we can't
reliably bsearch the index and tree content without applying a
`git_vector_sort()` first.
This also fixes some missed places where size_t can be used and
where const can be applied to a couple internal functions.
The index iterator could previously only be created from a repo
object, but this allows creating an iterator from a `git_index`
object instead (while keeping, though renaming, the old function).
