hgweb: use our forked wsgiheaders module instead of stdlib one Now we use bytes for headers, rather than native strings. Differential Revision: https://phab.mercurial-scm.org/D2854

wsgiheaders: import a bytes-ified fork of wsgiref.headers from cpython@46f5072 This will let us restore Python 3 compatibility for tests that do http things. Differential Revision: https://phab.mercurial-scm.org/D3245

export: enable formatter support (API) This change is basically the same as "hg cat". A formatter object is created by caller. .. api:: ``cmdutil.export()`` takes a formatter as an argument.

export: extract function to write patch to file object (API) This is common use case of cmdutil.export(), and we wouldn't want to handle formatter thingy everywhere. .. api:: The ``fp`` argument is removed from ``cmdutil.export()``. Use ``cmdutil.exportfile()`` instead.

export: port _exportsingle() to formatter Pass 'fm' instead of 'write', and use fm.plain(), fm.write(), etc. instead. The callers will be updated later.

export: serialize revisions to be exported per destination file Prepares for porting to the formatter API, where we can't simply append to existing files because JSON can't be streamed for example. The modemap hack is removed since cmdutil.export() was the only user. I also made the destination filename printed only once.

export: split cmdutil.export() to single-file and maybe-multiple-files cases Porting "hg export" to formatter is a bit hard because cmdutil.export() may append to files if the fntemplate is specified. This patch splits the hard part from the trivial case.

export: remove unused argument 'rev' from _exportsingle()

export: do not start pager if output will be written to file A copy of 3b569745af6c.

formatter: carry opts to file-based formatters by basefm This makes it slightly easier to port "hg export" to formatter.

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: 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
