largefiles: add copytostore() fstandin argument to replace readstandin() (API) copyalltostore(), only one caller of copytostore(), already knows standin file name of the target largefile. Therefore, passing it to copytostore() is more efficient than calculating it in copytostore() or readstandin().

largefiles: replace readstandin() by readasstandin() These code paths already (or should, for efficiency at repetition) know the target changectx and path of standin file.

largefiles: introduce readasstandin() to read hex hash from given filectx This will be used to centralize and encapsulate the logic to read hash from given (filectx of) standin file. readstandin() isn't suitable for this purpose, because there are some code paths, which want to read hex hash directly from filectx.

rebase: abort hg pull --rebase if rebase.requiredest is set (issue5514) Previously, the pull would succeed, but the subsequent rebase would fail due to the rebase.requiredest flag. Now abort earlier with a more useful error message.

rebase: demonstrate behavior with requiredest and pull --rebase

rebase: allow destination-free continue and abort (issue5513)

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.
