formatter: remove unused private attributes from baseformatter No idea what they were for.

fix: add --all flag to fix non-public non-obsolete revisions Differential Revision: https://phab.mercurial-scm.org/D3213

fsmonitor: layer on another hack in bser.c for os.stat() compat (issue5811) It's unclear to me how these `bserobj_tuple` objects are used, other than as stat objects. This should fix fsmonitor in the wake of ffa3026d4196 and similar changes. I regret the hack here, but the code already has plenty of hg-specific hacks. :( It feels like we should be able to use int(result.st_mtime) globally, but that doesn't work. See issue4836 for a bug that was hard to track down relating to rounding behavior causing very subtle dirstate problems. Differential Revision: https://phab.mercurial-scm.org/D2939

tests: use `f --newer` instead of `stat -c` in test-fix.t Also increase sleep to two seconds so this test will likely pass on FAT32. Differential Revision: https://phab.mercurial-scm.org/D3252

tests: glob away fqdn wherever we print it These localhost instances are actually from a getfqdn call, which means on some of my test systems it comes out as localhost.localdomain or 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa. I'm tired of this, so let's glob it away. Differential Revision: https://phab.mercurial-scm.org/D3251

hgweb: use native strings when interfacing with stdlib headers We're still parsing the stdlib-provided headers here, so we need to tread carefully and use native strings. Yuck. Differential Revision: https://phab.mercurial-scm.org/D3250

wireprotoserver: headers are bytes for us internally, use bytes This re-fixes test-pull-http.t on Python 3. Probably many others as well. Differential Revision: https://phab.mercurial-scm.org/D3249

hgweb: put response headers back into str for Python 3 This fixes a lot of hanging tests on Python 3, because "Content-Length" was getting sent as "b'Content-Length'" (yes, really) and then clients would expect a close-is-end body instead of counting off a certain number of bytes. Differential Revision: https://phab.mercurial-scm.org/D3248

tests: load showstack in test-pull-http.t so network hangs are easier to find This also gives us some minimal "it loads" coverage on showstack, which I rather like. showstack doesn't work on Windows per mbarbison, so it's disabled there. I added this in service of debugging a hang introduced on Python 3 by revision a88d68dc3ee8. I'm still not sure what the problem there is, but this at least gives us a little bit of a chance to figure out what's going on. Differential Revision: https://phab.mercurial-scm.org/D3247

keepalive: rewrite readinto() to not use read() It turns out http.client on Python 3 sometimes uses readinto() in the implementation of read(). Unfortunately, Python 2 doesn't have a readinto() in httplib's client, so we have to support both codepaths. Subclassing is bad, folks. Differential Revision: https://phab.mercurial-scm.org/D3246

py3: use bytes() instead of str() on util.url() We internally deal with bytes and anything as string breaks things. Differential Revision: https://phab.mercurial-scm.org/D3285

py3: use stringutil.forcebytestr() to convert error messages to bytes Differential Revision: https://phab.mercurial-scm.org/D3284

py3: suppress the return value of write() in tests/test-subrepo-missing.t write() on Python 3 returns a value whereas does not return anything on Python 2. So we need to supress the value. Differential Revision: https://phab.mercurial-scm.org/D3283

py3: add b'' prefixes in tests/test-linerange.py This makes the test pass on Python 3. # skip-blame because just b'' prefixes Differential Revision: https://phab.mercurial-scm.org/D3282

py3: add b'' prefix to make the regex bytes # skip-blame because just b'' prefix Differential Revision: https://phab.mercurial-scm.org/D3281

py3: use '%d' for integers instead of '%s' Differential Revision: https://phab.mercurial-scm.org/D3277

py3: prevent transformer from adding b'' by adding r'' prefix These are cases where we need to use str, therefore we add r'' prefix. # skip-blame because just r'' prefixes Differential Revision: https://phab.mercurial-scm.org/D3276

py3: use pycompat.{strkwargs|byteskwargs} in infinitepush Differential Revision: https://phab.mercurial-scm.org/D3275

diffhelpers: be more tolerant for stripped empty lines of CRLF ending Exchange. It appears to trim lines containing only whitespace as well as converting LF to CRLF.

diffhelpers: make return value of testhunk() more Pythonic It's no longer C.

patch: error out if reached to EOF while reading hunk This was where out-of-bounds read occurred in old C extension.
