fsmonitor: use custom stdint.h file when compiling with Visual C Visual C/C++ 9, which Python 2.7 is compatible with, doesn't have C99 support and thus doesn't contain a stdint.h file. This changeset adds a custom version of stdint.h, created specifically for Visual C, and uses it when building with that compiler.

tests: handle getaddrinfo reporting "No address associated with hostname" This has been seen on some Fedora 23 systems.

httpconnection: remove obsolete comment about open() When httpsendfile was moved from url.py into httpconnection.py in e7525a555a64 (url: use new http support if requested by the user, 2011-05-06), the comment about not being able to just call open() became obsolete.

sslutil: allow multiple fingerprints per host Certificate pinning via [hostfingerprints] is a useful security feature. Currently, we only support one fingerprint per hostname. This is simple but it fails in the real world: * Switching certificates breaks clients until they change the pinned certificate fingerprint. This incurs client downtime and can require massive amounts of coordination to perform certificate changes. * Some servers operate with multiple certificates on the same hostname. This patch adds support for defining multiple certificate fingerprints per host. This overcomes the deficiencies listed above. I anticipate the primary use case of this feature will be to define both the old and new certificate so a certificate transition can occur with minimal interruption, so this scenario has been called out in the help documentation.

help: add empty lines to hostfingerprints section I think this is now much easier to read.

help: document requirements We didn't have unified documentation of the various repository requirements. This patch changes that.

showstack: use absolute_import

contrib: use absolute_import in win32/hgwebdir_wsgi.py

dispatch: catch KeyboardInterrupt more broadly Because _runcatch() can run long operations in its exception handler, it wasn't enough to catch KeyboardInterrupt at the same level. For example, "hg unknown" will load all extension modules, so we could easily make it crashed by Ctrl-C.

histedit: have dropmissing abort on empty plan We noticed that many users have the intuition of laving the editor empty when they want to abort the operation. The fact that dropmissing allows user to delete all edited commits is not intuitive even for users that asked for it. Let's prevent people from this footgun.

streamclone: fix error when store files grow while stream cloning Effectively a backout of 9fea6b38a8da, but updated to using 'with'.

tests: add test of stream clone of repo that is changing This reveals an error introduced by 9fea6b38a8da.

chgserver: handle ParseError during validate Currently the validate command in chgserver expects config can be loaded without issues but the config can be broken and chg will print a stacktrace instead of the parsing error, if a chg server is already running. This patch adds a handler for ParseError in validate and a new instruction "exit" to make the client exit without abortmsg. A test is also added to make sure it will behave as expected.

dispatch: extract common logic for handling ParseError The way ParseError is handled at two different places in dispatch.py is the same. Move common logic into _formatparse.

chgserver: resolve relative path before sending via system channel The chgserver may have a different cwd from the client because of the side effect of "--cwd" and other possible os.chdir done by extensions. Therefore relative paths can be misunderstood by the client. This patch solves it by expanding relative cwd path to absolute one before sending them via the 'S' channel. It can help chg to pass a testcase in test-alias.t later.
