test-lfs: dial up the debugging on commands that interact with the server This will be useful to let the client print out the HTTP headers and JSON in a future patch, so we can compare native LFS serving against test-lfs-server behavior. There tends to be a lot of debug stuff that we don't care about here in a push, so I was tempted to print this output with a [devel] config. But this will be useful for field debugging too, so just put up with the extra output here. It would have been nice to be able to set ui.debug once, but issue5815 prevents that.

tests: add a substitution pattern for dates in HTTP headers and LFS payload This will be useful when printing HTTP headers and JSON payload received from an LFS server. The RFC 1123 date masking has uses elsewhere too.

xdiff: fix a hard crash on Windows The xdiff case of test-diff-antipatience.t started crashing in the C extension with 882657a9f768 (with 6a71a5ba666b backported so it compiles). There are a few more instances of 'long', but this resolves the crashing.

templater: split template functions to new module It has grown enough to be a dedicated module.

templater: move hybrid class and functions to templateutil module And make _hybrid and _mappable classes public. _showlist() is still marked as private since it's weird and third-party codes shouldn't depend on it.

templater: move stringify() to templateutil module As we have a util module, it doesn't make sense to import stringify() from templatefilters.py.

dagop: move lines() out of annotate()

dagop: extract core algorithm of annotate() from context.py See the previous patch for why.

dagop: move annotateline and _annotatepair from context.py The annotate logic is large. Let's move it out of the context module, which is basically an abstraction layer of repository operations.

bdiff: convert more longs to int64_t MSVC previously flagged these where the function is stored in a pointer: bdiff.c(284) : warning C4028: formal parameter 1 different from declaration bdiff.c(284) : warning C4028: formal parameter 2 different from declaration bdiff.c(284) : warning C4028: formal parameter 3 different from declaration bdiff.c(284) : warning C4028: formal parameter 4 different from declaration

xdiff: silence a 32-bit shift warning on Windows It's probably harmless, but: warning C4334: '<<' : result of 32-bit shift implicitly converted to 64 bits (was 64-bit shift intended?) Adding a 'ULL' suffix to 1 also works, but I doubt that's portable.

xdiff: backport int64_t and uint64_t types to Windows Sadly, MSVC 2008 lacks stdint.h. These are the only two definitions needed right now.

templater: extract template evaluation utility to new module Prepares for splitting template functions to new module. All eval* functions were moved to templateutil.py, and run* functions had to be moved as well due to the dependency from eval*s. eval*s were aliased as they are commonly used in codebase. _getdictitem() had to be made public.

templater: move function table to the "context" object Prepares for splitting template functions from templater.py.

hgweb: remove wsgirequest (API) Good riddance. .. api:: The old ``wsgirequest`` class for handling everything WSGI in hgweb has been replaced by separate request and response types. Various high-level functions in the hgweb WSGI applications now receive these new types as arguments instead of the old ``wsgirequest`` type. Differential Revision: https://phab.mercurial-scm.org/D2832

tweakdefaults: add commands.status.verbose to tweakefaults commands.status,verbose if set to True, shows conflict information in `hg status`. It shows which unresolved state you are in, which are the unresolved files and how to continue the unresolved state. That sounds like a very good candidate for tweakdefaults. bisect is added to commands.status.skipstates because people generally leave unresolved bisect state and we should skip that in morestatus output.

hgweb: store the raw WSGI environment dict We need this so we can construct a new request instance from the original dict. Differential Revision: https://phab.mercurial-scm.org/D2831

hgweb: remove dead wsgirequest code All responses now go through our modern response type. All code related to response handling can be deleted. Differential Revision: https://phab.mercurial-scm.org/D2830

hgweb: port to new response API These were the last consumers of wsgirequest.respond() \o/ Differential Revision: https://phab.mercurial-scm.org/D2829

hgweb: pass modern request type into templater() Only a handful of consumers of wsgirequest remaining in this file... Differential Revision: https://phab.mercurial-scm.org/D2828

hgweb: use modern response type for index generation Differential Revision: https://phab.mercurial-scm.org/D2827

hgweb: don't pass wsgireq to makeindex and other functions We only ever access attributes that are available on our newer request type. So we no longer need this argument. Differential Revision: https://phab.mercurial-scm.org/D2826

hgweb: replace PATH_INFO with dispatchpath This was the last consumer of wsgireq.env from our WSGI applications! (Although indirect consumers of this attribute exist in wsgirequest.respond().) Differential Revision: https://phab.mercurial-scm.org/D2825

hgweb: rewrite path generation for index entries I think this code is easier to read. But the real reason to do this is to eliminate a consumer of wsgirequest. Differential Revision: https://phab.mercurial-scm.org/D2824

hgweb: construct {url} with req.apppath This is how the hgweb WSGI application does it. Let's make the behavior consistent. Differential Revision: https://phab.mercurial-scm.org/D2823

hgweb: support constructing URLs from an alternate base URL The web.baseurl config option allows server operators to define a custom URL for hosted content. The way it works today is that hgwebdir parses this config option into URL components then updates the appropriate WSGI environment variables so the request "lies" about its details. For example, SERVER_NAME is updated to reflect the alternate base URL's hostname. The WSGI environment should not be modified because WSGI applications may want to know the original request details (for debugging, etc). This commit teaches our request parser about the existence of an alternate base URL. If defined, the advertised URL and other self-reflected paths will take the alternate base URL into account. The hgweb WSGI application didn't use web.baseurl. But hgwebdir did. We update hgwebdir to alter the environment parsing accordingly. The old code around environment manipulation has been removed. With this change, parserequestfromenv() has grown to a bit unwieldy. Now that practically everyone is using it, it is obvious that there is some unused features that can be trimmed. So look for this in follow-up commits. Differential Revision: https://phab.mercurial-scm.org/D2822

hgweb: clarify that apppath begins with a forward slash Differential Revision: https://phab.mercurial-scm.org/D2821

hgweb: change how dispatch path is reported When I implemented the new request object, I carried forward some ugly hacks until I could figure out what was happening. One of those was the handling of PATH_INFO to determine how to route hgweb requests. Essentially, if we have PATH_INFO data, we route according to that. But if we don't, we route by the query string. I question if we still need to support query string routing. But that's for another day, I suppose. In this commit, we clean up the ugly "havepathinfo" hack and replace it with a "dispatchpath" attribute that can hold None or empty string to differentiate between the presence of PATH_INFO. This is still a bit hacky. But at least the request parsing and routing code is explicit about the meaning now. Differential Revision: https://phab.mercurial-scm.org/D2820
