convert: also catch missing revlogs when introduced in repo roots
The previous behaviour was almost as if convert.hg.ignoreerrors was always set
for revisions without parents, except that errors were silently ignored. Revlog
errors are handled as a side effect of getcopies(), but getcopies() was only
called when convert.hg.ignoreerrors was set.
Now we always call self.getcopies for root revisions, not only when
convert.hg.ignoreerrors is set, just like we do on all other revisions.
The extra call might be a bit expensive, but the proper fix for that would be
to catch these errors in another way.
status: remove unreachable code for status between revisions
The manifest value of a file will never be false when "not parentworking", and
the expensive content comparision would thus fortunately never be reached. (If
it was reached it would be wrong for example in case of renames.)
This code once handled status against working directory, but that has been done
elsewhere for a long time.
httprepo: proper handling of invalid responses without content-type (
issue2019)
This can currently be tested on http://sf.net/
httprepo: use the original exception after falling back to static-http failed
Before the fine exception handling in httprepo was never shown.
The static-http exception will now only be shown when static-http is requested
explicitly.
unbundler: separate delta and header parsing
Add header parsing for changelog and manifest (currently no headers might
change for next-gen bundle).
