rebase: test to show brokenness with requiredest As shown in issue5513, --continue is broken when destination is required. This adds a patch that demonstates this silly behavior, which will be fixed in a future patch.

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.

sslutil: clarify internal documentation I ran into this python issue with an incomplete certificate chain on Windows recently, and this is the clarification that came from that experimenting. The comment I left on the bug tracker [1] with a reference to the CPython code [2] indicates that the original problem I had is a different bug, but happened to be mentioned under issue20916 on the Python bug tracker.

unionrepo: avoid unnecessary node -> rev conversion

bundlerepo: avoid unnecessary node -> rev conversion

revlog: avoid unnecessary node -> rev conversion

check-code: detect r.revision(r.node(rev)) revlog.revision takes either node or rev, but taking a rev is more efficient, because converting rev to node is just a seek and read. That's cheaper than converting node to rev, which may require O(n) walk in revlog index for the first times, and then triggering building the radix tree index. Even with the radix tree built, rev -> node is still faster than node -> rev because the radix tree requires more jumps in memory. So r.revision(r.node(rev)) should be changed to r.revision(rev). This patch adds a check-code rule to detect that.
