httppeer: properly gate debug usage behind debug flag check The "dbg" local variable is only defined if the 'debugflag' is set to True. However, it was used indiscriminately later in the function. We hide its usage behind the 'debugflag' value to avoid raising a NameError.

push: continue without locking on lock failure other than EEXIST (issue5882) This code was added by 3f5e75c22585 "push: make locking of source optional (issue3684)", but EACCES isn't the only error that could be triggered by filesystem permission. I think catching LockUnavailable is more appropriate than testing errno value by caller.

bdiff: fix yet more fallout from xdiff long/int64 conversion (issue5885) "l" in Py_BuildValue's format string means long, so passing int64_t instead results in fireworks on 32bit architectures. Differential Revision: https://phab.mercurial-scm.org/D3538

revset: pass in lookup function to matchany() (issue5879) Silly mistake in f83cb91b052e.

test-hgweb: add test for foo-bar name lookup This is broken since f83cb91b052e "revset: pass in lookup function instead of repo (API)."

bundle2: mark the bundle2 part as advisory (issue5872) It blocks old clients to read bundle including this part. Differential Revision: https://phab.mercurial-scm.org/D3481

debugbundle: also display if a part is mandatory or advisory Most parts are mandatory but when introducing new parts, they should be advisory if included by default or old clients won't be able to process it. Differential Revision: https://phab.mercurial-scm.org/D3480
