streamclone: ensure the server sends the right amount of data Otherwise, the client would fail with some confusing error. I have seen an error which I think is this, perhaps due to a concurrent revlog split, which streamclones do not handle correctly and would result in a short read of the index of the revlog being split.

rewriteutil: fix crash when a rewritten message references f{6,64} Without this, the rewriteutil logic thinks it's found a reference to the wdir pseudo-revision, and then tries to look it up and rewrite it. Stop it from doing that. Amusingly, I had trouble working with this changeset when I didn't describe the defect above using a regular expression, because it would trigger the bug in my installed version of hg.

tests: add explicit coverage for update_hash_refs from rewriteutil I couldn't find any evidence this is covered by tests in core (but there's a good chance I missed it). We've seen a cute bug in that code, but first let's just cover the cases that work correctly. Differential Revision: https://phab.mercurial-scm.org/D11231

store: document the decoding discrepancy in store.py This will help future people that might be looking into this. Differential Revision: https://phab.mercurial-scm.org/D11220

clone: add a file with special character while testing uncompressed This will make sure we currently do not have any actual impact from issue6548. Differential Revision: https://phab.mercurial-scm.org/D11219

clone: test local clone in `test-clone-uncompressed.t` too This is not an uncompressed test but needs to be tested in the same kind of constraints regarding special file name. Differential Revision: https://phab.mercurial-scm.org/D11218

test-transaction-safety: relax some of the synchronisation schedule We can have `internal` and `external` runs at the same time, so we unlock `external` a bit sooner. Differential Revision: https://phab.mercurial-scm.org/D11216
