I accidentally wrote a separate priority queue implementation when
I was working on file rename detection as part of the file hash
signature calculation code. To simplify licensing terms, I just
adapted that to a general purpose priority queue and replace the
old priority queue implementation that was borrowed from elsewhere.
This also removes parts of the COPYING document that no longer
apply to libgit2.
Validating the workdir should not compare HEAD to working
directory - this is both inefficient (as it ignores the cache)
and incorrect. If we had legitimately allowed changes in the
index (identical to the merge result) then comparing HEAD to
workdir would reject these changes as different. Further, this
will identify files that were filtered strangely as modified,
while testing with the cache would prevent this.
Also, it's stupid slow.
The checkout code used to defer removal of "blocking" files in
checkouts until the blocked item was actually being written (since
we have already checked that the removing the block is acceptable
according to the update rules). Unfortunately, this resulted in
an intermediate index state where both the blocking and new items
were in the index which is no longer allowed. Now we just remove
the blocking item in the first pass so it never needs to coexist.
In cases where there are typechanges, this could result in a bit
more churn of removing and recreating intermediate directories,
but I'm going to assume that is an unusual case and the churn will
not be too costly.
There were some confusing issues mixing up the number of bytes
written to the zstream output buffer with the number of bytes
consumed from the zstream input. This reorganizes the zstream
API and makes it easier to deflate an arbitrarily large input
while still using a fixed size output.
This removes the fetchRecurse compiler warnings and makes the
behavior match the other submodule options (i.e. the in-memory
setting can be reset to the on-disk value).
- Add correct -I, -L and -l flags
- Search for libiconv in /opt/local/[include|lib] before in the
system path. See #2017 for details.
- Give splitted -L and -l arguments to pkg-config
