trydiff: use sets, not lists, for containment checks This only has a noticeable effect on diffs touching A LOT of files. For example, it takes hg diff -r FIREFOX_AURORA_30_BASE -r FIREFOX_AURORA_35_BASE from 1m55.465s to 1m32.354s. That diff has over 50k files.

largefiles: fix unused import Caught by pyflakes.

largefiles: look at unfiltered().lfstatus to allow status() to be filtered The comment about status being buggy with a repo proxy seems to be that status wasn't being redirected to testing the largefiles themselves- lfstatus was always False, and so the original status method was being called instead of doing the largefiles processing. This is because when the various largefile command overrides call 'repo.lfstatus = True', __setattr__() in repoview is in turn setting the value on the unfiltered repo, and the value in the filtered repo remains False. Explicitly looking at the attribute on the unfiltered repo keeps all views in sync.

largefiles: eliminate a duplicate message when removing files in verbose mode There is no --after for addremove, so the printing for addremove can be hoisted out of the 'not after' check. The difference between the two remove messages reflects the existing difference between core remove and core addremove styles for printing the file. There are still some pre-existing issues here. Core addremove only prints on inexact matches or when verbose. But since the largefiles that are being removed are passed to removelargefiles() as a pattern list, there is never an inexact match, which would keep the largefiles from being printed at all unless verbose is specified. Therefore, the output is a little more aggressive than core. The addremove print style here is also inconsistent with core- it should use matcher.uipath(f) instead of f. These can be fixed once a matcher is passed in.

largefiles: ensure that the standin files are available in getlfilestoupload() The function only adds the hash content of the file to the set to upload if the file in the ctx is a standin. It is called by overrides.summaryremotehook(), which is called in the summary method. The largefiles extension switches 'lfstatus' on in summary, so the standins shouldn't be visible when obtaining a context there. The reason this wasn't noticed before is that the 'lfstatus' attribute is only being set on the unfiltered repo because of how repoview delegates attribute assignment. Therefore any filtered view will return a context containing standins, whether or not 'lfstatus' was set in the various overrides methods. That will be fixed in the next patch. But without this change, the next patch would have test failures for 'summary --large' stating there are no files to upload.

merge: move checking of unknown files out of manifestmerge() This moves most reading of filelogs out of manifestmerge, making it easy for a narrow clone extension to filter out or translate unwanted actions before any filelogs are read. The only call left is inside of copies.mergecopies(), which can be overridden separately at a lower level.
