treemanifests: fix streaming clone Similar to the previous patch, the .hg/store/meta/ directory does not get copied when when using "hg clone --uncompressed". Fix by including "meta/" in store.datafiles(). This seems safe to do, as there are only a few users of this method. "hg manifest" already filters the paths by "data/" prefix. The calls from largefiles also seem safe. The use in verify needs updating to prevent it from mistaking dirlogs for orphaned filelogs. That change is included in this patch. Since the dirlogs will now be in the fncache when using fncachestore, let's also update debugrebuildfncache(). That will also allow any existing treemanifest repos to get their dirlogs into the fncache. Also update test-treemanifest.t to use an a directory name that requires dot-encoding and uppercase-encoding so we test that the path encoding works.

treemanifests: fix local clone When doing a local clone with treemanifests, the .hg/store/meta/ directory currently does not get copied. To fix it, all we need to do is to add it to the list of directories to copy.

tests: simplify treemanifest test by backing up entire .hg/store

histedit: limit updated and merging output to important updates Output is retained when: * There's a conflict * User asked to edit * User aborts otherwise, output is suppressed

tests: fix rebase-abort directory nesting Without this change, some test repositories were nesting needlessly

rebase: document that tool does not apply to deleted files

rebase: mention help merge-tools in help

copies: optimize forward copy detection logic for rebases Forward copy detection (i.e. detecting what files have been moved/copied in commit X since ancestor Y) previously required diff'ing the manifests of both X and Y. This was expensive since it required reading both entire manifests and doing a set difference (they weren't already in a set because of the lazymanifest work). This cost almost 1 second on very large repositories, and happens N times for a rebase of N commits. This patch optimizes it for the case of rebase. In a rebase, we are comparing a commit against it's immediate parent, and therefore we can know what files changed by looking at ctx.files(). This lets us drastically decrease the size of the set comparison, and makes it O(# of changes) instead of O(size of manifest). This makes it take 1ms instead of 1000ms.

tests: pass settings of hypothesis by with statement given(..., settings=) is no longer available in Hypothesis 2.0.0. https://github.com/DRMacIver/hypothesis/commit/7712c01

tests: adjust for code move in Hypothesis 2.0.0 It appears that the Settings class was renamed to settings, and because of this, the settings module was renamed to configuration. https://github.com/DRMacIver/hypothesis/commit/a0e663b
