bundle2: use pycompat.strkwargs as needed Differential Revision: https://phab.mercurial-scm.org/D2303

tests: add b prefixes to test-rebase-dest.t # skip-blame just b prefixes Differential Revision: https://phab.mercurial-scm.org/D2302

rebase: sort roots by revision Previously we were sorting them by whatever implicit sort order we got between changectx instances. Sorting by rev at least makes some sense, so I chose that. Differential Revision: https://phab.mercurial-scm.org/D2301

httppeer: use %d to format int Differential Revision: https://phab.mercurial-scm.org/D2300

extensions: reject any unicode strings in tables before loading This allows us to test hg on Python 3 without disabling third-party extensions which could pollute cmdtable for example.

py3: make test-extdiff.t pass on Python 3

py3: make regexp patterns bytes in extdiff

py3: fix bytes-unicode dance while building docstring of extdiff

py3: factor out byterepr() which returns an asciified value on py3

remotenames: don't use the default value of logfmt for namespaces logfmt is the format which is used to format the log output for that namespace. This patch passes "remote {bookmark|branch}: %s" as the logfmt. Space is not added after bookmark and branch to make output consistent with other details. Still this is not the best output. We may need to wrap getlogcolumns() to change spacing in the in built columns to match the remotenames one. lognames are also deleted as they are superseded by logfmt.

py3: whitelist test-pull-http.t There's a lot of work left to do on network-related stuff, but I at least got one more test passing. Differential Revision: https://phab.mercurial-scm.org/D2296

scmutil: bytes-ify IOErrors before wrapping them in abort message Differential Revision: https://phab.mercurial-scm.org/D2292

py3: port f to Python 3 This involved a lot of b'' literals, conversion from %s to %d, and using a hashing mechanism that returns bytes instead of str. Differential Revision: https://phab.mercurial-scm.org/D2299

py3: replace file() with open() in test-convert-git.t file() is not present in Python 3. It also makes sure we write bytes on Python 3. Differential Revision: https://phab.mercurial-scm.org/D2133

bundle: updates the help text for hg bundle (issue5744) Differential Revision: https://phab.mercurial-scm.org/D2278

py3: get bytes-repr of network errors portably This resolves a lot of weird issues in Python 3 around error strings. Differential Revision: https://phab.mercurial-scm.org/D2295

hgweb: open server logs in binary mode This is consistent with when we're logging to stdout, so we don't have to do something annoyingly complicated in the logging infrastructure. Differential Revision: https://phab.mercurial-scm.org/D2294

tests: add some b prefixes in test-http-bundle1.t # skip-blame just some b prefixes Differential Revision: https://phab.mercurial-scm.org/D2293

hgweb: correctly bytes-ify status, not string-ify Differential Revision: https://phab.mercurial-scm.org/D2291

printenv: port to python3 Differential Revision: https://phab.mercurial-scm.org/D2290

py3: whitelist another eight passing tests Differential Revision: https://phab.mercurial-scm.org/D2281

remotenames: port partway to python3 by using collections.MutableMapping test-logexchange.t doesn't pass after this, but at least the remotenames extension can be imported. Differential Revision: https://phab.mercurial-scm.org/D2280

tests: avoid referring to pvec in demandimport test Nothing else currently uses pvec, so we may want to delete it (but Augie Fackler says he may want to use it). To enable deletion, this patch replaces it by the error module in the demandimport test (any module works). However, since the error module had already been loaded at this point in the test (via the util module), I moved it earlier in the test so it's still not loaded (although I'm not sure if that's even relevant to the test).

help: use cmdutil.parsealiases() to resolve command name This seems slightly better than parsing '^command|name' string by using an ad-hoc pattern.

help: list deprecated and experimental extensions if --verbose This is common in the other help topics.

hgweb: translate Abort in help command to 404 error c3784e3c3e8d changed the exception type to be raised if unknowncmd=False.

templatekw: add {reporoot} keyword The "%b" in filename format string will be replaced with "{reporoot|basename}".

templatefilters: add dirname() filter This is different from stripdir() in that the last component is always removed.

templater: add function to help substituting patterns in template string This will be used to rewrite a filename pattern to a template string.

templater: extract function scanning template string This provides a tokenizer-level view of template fragments, and will be used to substitute patterns in outermost 'string' tokens.
