rebase: move destination test to new test file We'll be adding a lot more tests here, so it makes sense to have this in its own file now.

templatefilter: add support for 'long' to json() When disabling the '#requires serve' check in test-hgwebdir.t and running it on Windows, several 500 errors popped up when querying '?style=json', with the following in the error log: File "...\\mercurial\\templater.py", line 393, in runfilter "keyword '%s'") % (filt.func_name, dt)) Abort: template filter 'json' is not compatible with keyword 'lastchange' The swallowed exception at that point was: File "...\\mercurial\\templatefilters.py", line 242, in json raise TypeError('cannot encode type %s' % obj.__class__.__name__) TypeError: cannot encode type long This corresponds to 'lastchange' being populated by hgweb.common.get_stat(), which uses os.stat().st_mtime. os.stat_float_times() is being disabled in util, so the type for the times is 'long' on Windows, and 'int' on Linux.

hgweb: prefix line id by ctx shortnode in filelog when patches are shown When "patch" query parameter is present in requests to filelog view, line ids in patches diff are no longer unique in the page since several patches are shown on the same page. We now prefix line id by changeset shortnode when several patches are displayed in the same page to have unique line ids overall.

test-check-code: prevent files being added to the root directory Adding new files in the root directory is probably a mistake, and is usually discouraged [1]. The test catches it to avoid mistakes like [2]. Modify the test if files need to be added in the root.
