tests: disable remotefilelog on Windows I've spent a non trivial amount of time trying to eliminate the test errors, but it's looking like this is pretty dependent on Unix support. For example, there are attempts to delete open files, and uses of threads that report I/O attempts on closed files. (Maybe this is a race condition? Don't we usually use processes as workers on Windows?) In any event, I don't want real new errors elsewhere to be masked by these known problems. For some reason $CACHEDIR is reported as missing in test-remotefilelog-repack.t, but it actually exists in the hgcloneshallow call inside shallowutil.mkstickygroupdir(). By the time the process exits, it's gone. I don't see it being removed by code that calls 'rmdir' or 'remove' in the extension itself.

perf: run 'setup' function during stub run The benchmarked function might need the content of the setup to be run in order to function properly.

perf: fallback to subset if ondisk cache is missing in perfbranchmapload If there is no branchmap on disk for that filter, it means that the cache from some subset's filter is relevant for this one. We look for it instead of aborting. That way it is much simpler to run the command in an automated way. We can now add it to `test-contrib-perf.t`.

perf: prewarm the branchmap in perfbranchmapload It is not very interesting to have the command randomly failing because the branchmap for the tested filter happens to be cold. So we make sure to have a valid up to date branchmap before going further. The data might still be missing from disk if a subset was equivalent. See next changeset for details and fix.

localrepo: correct docstring of filectx() The same reason as b6c2543e1dd8. It can't be any changeset specifiers but revision number.

annotate: remove dead code to not convert path to relative path It's annotate. There should be at least one file path specified.

annotate: start pager soon after command options are validated It helps extracting helper class.

annotate: check and update command options first It helps extracting helper class.
