localrepo: make supported features manageable in each repositories individually
Before this patch, all localrepositories support same features,
because supported features are managed by the class variable
"supported" of "localrepository".
For example, "largefiles" feature provided by largefiles extension is
recognized as supported, by adding the feature name to "supported" of
"localrepository".
So, commands handling multiple repositories at a time like below
misunderstand that such features are supported also in repositories
not enabling corresponded extensions:
- clone/pull from or push to localhost
- recursive execution in subrepo tree
"reposetup()" can't be used to fix this problem, because it is invoked
after checking whether supported features satisfy ones required in the
target repository.
So, this patch adds the set object named as "featuresetupfuncs" to
"localrepository" to manage hook functions to setup supported features
of each repositories.
If any functions are added to "featuresetupfuncs", they are invoked,
and information about supported features is managed in each
repositories individually.
This patch also adds checking below:
- pull from localhost: whether features supported in the local(= dst)
repository satisfies ones required in the remote(= src)
- push to localhost: whether features supported in the remote(= dst)
repository satisfies ones required in the local(= src)
Managing supported features by the class variable means that there is
no difference of supported features between each instances of
"localrepository" in the same Python process, so such checking is not
needed before this patch.
Even with this patch, if intermediate bundlefile is used as pulling
source, pulling indirectly from the remote repository, which requires
features more than ones supported in the local, can't be prevented,
because bundlefile has no information about "required features" in it.

# An example WSGI script for IIS/isapi-wsgi to export multiple hgweb repos # Copyright 2010 Sune Foldager <cryo@cyanite.org> # # This software may be used and distributed according to the terms of the # GNU General Public License version 2 or any later version. # # Requirements: # - Python 2.6 # - PyWin32 build 214 or newer # - Mercurial installed from source (python setup.py install) # - IIS 7 # # Earlier versions will in general work as well, but the PyWin32 version is # necessary for win32traceutil to work correctly. # # # Installation and use: # # - Download the isapi-wsgi source and run python setup.py install: # http://code.google.com/p/isapi-wsgi/ # # - Run this script (i.e. python hgwebdir_wsgi.py) to get a shim dll. The # shim is identical for all scripts, so you can just copy and rename one # from an earlier run, if you wish. # # - Setup an IIS application where your hgwebdir is to be served from. # On 64-bit systems, make sure it's assigned a 32-bit app pool. # # - In the application, setup a wildcard script handler mapping of type # IsapiModule with the shim dll as its executable. This file MUST reside # in the same directory as the shim. Remove all other handlers, if you wish. # # - Make sure the ISAPI and CGI restrictions (configured globally on the # web server) includes the shim dll, to allow it to run. # # - Adjust the configuration variables below to match your needs. # # Configuration file location hgweb_config = r'c:\src\iis\hg\hgweb.config' # Global settings for IIS path translation path_strip = 0 # Strip this many path elements off (when using url rewrite) path_prefix = 1 # This many path elements are prefixes (depends on the # virtual path of the IIS application). import sys # Adjust python path if this is not a system-wide install #sys.path.insert(0, r'c:\path\to\python\lib') # Enable tracing.
