revlog: move check for wdir from changelog to revlog Yuya said he preferred this (to keep them in one place, I think). Differential Revision: https://phab.mercurial-scm.org/D569

debugssl: allow a URL to be specified without a local repository This was the original intent, but I bungled the logic. Otherwise if there is a certificate chain issue, the repository can't be cloned in order for there to be a repo object. I think I missed this case because I was inside of a Mercurial clone as I was originally developing and testing this.

revlog: use pycompat.bytestr() to reliably have a %s-able value

debugcommands: stabilize output of debugbundle by having a custom repr We handle all dict-like things the same, and don't worry about it actually being a repr.

python3: whitelist another 5 passing tests found with the ratchet script

python3: replace sorted(<dict>.iterkeys()) with sorted(<dict>)

python3: wrap all uses of <exception>.strerror with strtolocal Our string literals are bytes, and we mostly want to %-format a strerror into a one of those literals, so this fixes a ton of issues.

pager: do not start pager if `ui` has been `pushbuffer`-ed The `pushbuffer`, `popbuffer` APIs are intended to capture internal output. They will prevent `ui.write` from writing to the actual `ui.fout`. So a pager won't receive the output and do the right thing. In general, it does not make sense to start a pager if ui is in the "pushbuffer" mode. Differential Revision: https://phab.mercurial-scm.org/D574

revset: do not flip "and" arguments when optimizing Rewrite `flipand(y, x)` to `andsmally(x, y)` so the AST order is unchanged, which could be more friendly to developers. Differential Revision: https://phab.mercurial-scm.org/D579

revset: make match function follow given subset if specified (API) This should be sensible default since mfunc(subset) is roughly equivalent to 'subset & mfunc'. The order argument is still there so we can specify 'anyorder' if the order doesn't really matter.
