cmdutil: pass in parsed patch to tryimportone() (API) Previously, we parsed the patch in tryimportone(). This assumes the input is in a patch format that needs to be parsed. We want to support feeding in data from other formats. So let's let the caller handle the parsing. One wonky thing about patch parsing is that patch.extract() creates a temp file to hold the diffs and it is up to tryimportone() to unlink that temp file. I'll improve this in a subsequent commit.

stringutil: support more types with pprint() bytearray wasn't working. Integers and floats were not being formatted. I /think/ %f is portable across both Python 2 and 3, as it should default to 6 decimal points on each. Differential Revision: https://phab.mercurial-scm.org/D3302

fix: port most of the way to python 3 Only most of the way because we now have to decide: if we want to keep the current .format() interface for the config in hgrc, we have to use unicodes to do formatting in Python 3, rather than bytes. I'm basically fine with that, so a follow-up patch will do so. Differential Revision: https://phab.mercurial-scm.org/D3300

lfs: teach the blob server to handle --prefix

hgweb: fallback to checking wsgireq.env for REPO_NAME for 3rd party hosting Starting with d7fd203e36cc, SCM Manager began to 404 any repository access. What's happening is that it is generating a python script that creates an hgweb application (not hgwebdir), and launches hgweb via wsgicgi. It must be setting REPO_NAME in the process environment before launching this script, which gets picked up and put into wsgireq.env when wsgicgi launches the hgweb application. >From there, other variables (notably 'apppath' and 'dispatchpath') are constructed differently. d7fd203e36cc^ (working): apppath: /hg/eng/devsetup dispatchpath: pathinfo: /eng/devsetup reponame: eng/devsetup d7fd203e36cc: apppath: /hg dispatchpath: eng/devsetup pathinfo: /eng/devsetup reponame: None REPO_NAME: eng/devsetup Rather than having an existing installation break when Mercurial is upgraded, just resume checking the environment. I have no idea how many other hosting solutions would break without restoring this.

peer: scatter module to the wind (API) peer.py hardly contained any code. The code it did contain was generic to the version 1 peer interface or specific to the local repository peer. So code has been moved to wireprotov1peer and localrepo, as appropriate. Differential Revision: https://phab.mercurial-scm.org/D3260

wireproto: move version 1 peer functionality to standalone module (API) wireproto.py contains code for both the client and the server. There *should* be a somewhat strong separation between the two. This commit extracts the client-side code from wireproto.py into a new module - wireprotov1peer. Differential Revision: https://phab.mercurial-scm.org/D3259

wireproto: move gboptsmap to wireprototypes and rename (API) This is also shared between client and server and will need to exist in a shared module when that code is split into different modules. Differential Revision: https://phab.mercurial-scm.org/D3258

wireproto: move value encoding functions to wireprototypes (API) These functions should live in the same place. I plan to separate client from server code in upcoming commits. wireprototypes is where we are putting shared code like this. Differential Revision: https://phab.mercurial-scm.org/D3257

httppeer: basic implementation of capabilities interface This is a bit crude. The capabilities mechanism for version 2 of the wire protocol is a bit different from version 1. And code in core is relying on strings passed to capable() matching strings advertised by the "capabilities" wire protocol command. I may refactor the internal checking mechanism to be a bit more abstract or based on interfaces. Time will tell... Differential Revision: https://phab.mercurial-scm.org/D3256

repository: split capabilities methods into separate interface So we can implement them without having to implement support for every command. Differential Revision: https://phab.mercurial-scm.org/D3255

httppeer: implement ipeerconnection This is low hanging fruit. We might as well start somewhere. Differential Revision: https://phab.mercurial-scm.org/D3254

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.
