subrepo: correctly handle git subdirectory status change 'git diff-index' by default does not recurse into subdirectories when changes are found. As a result, the directory is shown as changed, rather than the files in this directory. Adding '-r' results in recursing until the blobs themselves are checked.

setup: hide octal literals inside strings so they're portable (issue4554)

revset: avoid returning duplicates when returning ancestors Before this patch, _revancestors were giving false result when a revision was duplicated in the input. Duplicated entry are rare but may happen when using the `%lx` notation internally. This series has no visible impact on the performance of the function according to benchmark.

revset: use an iterator instead of a dequeue in ancestors() The dequeue was actually just used to be able to pop value one at a time. Building the dequeue means we are reading all the input value at once at the beginning of the evaluation. This defeat the lazyness of revset. We replace the deque with iterator usage for the sake of simplicity and lazyness. This provide massive speedup to get the first result if the input set is big max(::all()) before) wall 0.001917 comb 0.000000 user 0.000000 sys 0.000000 (best of 1115) after) wall 0.000107 comb 0.000000 user 0.000000 sys 0.000000 (best of 22222)

revset: return early when revs is empty By introducing an early return in _revancestors() when revs is empty, we make it so inputrev is never None, which simplifies the subsequent code.

revset: rename 'revsnode' to 'inputrev' in ancestors We usually use 'node' for variable containing 20 bytes hash. There is nothing nodish in this variable, so we rename it to "inputrev" as it old the next entry of the iteration.

revset: make generatorset.__nonzero__ lazy The 'for r in self:' call could trigger full consumption of the generator while we only need a single value. We also fast path if a single value got already computed. See inline comment for more details. This provide massive speedup for lazy operation using boolean testing. max(::tip) e5b507efb36e) wall 0.055609 comb 0.060000 user 0.060000 sys 0.000000 (best of 100) after change) wall 0.000109 comb 0.000000 user 0.000000 sys 0.000000 (best of 19146)

tests: test that we can convert to manifestv2 with clone This just adds a test to ensure that we can convert a manifestv1 repo to a manifestv2 repo (for future commits only) by means of a local clone.

requires: move requires file writing func from localrepo to scmutil The logic to read a requires file resides in scmutil, so it's only logical that the logic to write the file should be there too. And now I've typed logic too many times it no longer looks like a word. Logically.

histedit: fix test-histedit-edit on vfat test-histedit-edit was broken because it relied on the HGEDITOR script being executable. Instead, lets just execute 'sh' and pass it the script to run. This seems to be the pattern followed in other tests.

revset: don't error out if tokens parse as existing symbols It makes perfect sense for tokens to parse as existing revset symbols (revset functions), and doesn't break anything, since parsing symbols as functions works correctly in the presence of parens. For example, if "only" is a bookmark, this used to error out, hg log -r "only(only, @)" which shouldn't, as the inner "only" is unambiguously not a function. So we just remove the symbolset function and replace its calling site with the stringset function. For the tests, we confirm that "date" and "only" are both parsed as revision names both inside revset expressions (e.g. an expression containing ::) and inside old-style revision expressions (e.g. those containing the name of the revision alone).

test-command-template: minor clarification in comment

test-command-template: test the phase template more precisely The current test that greps for "phase:" only checks that the word "phase" is in the output, but does not test that nothing else gets added by this template. This improves these tests by showing a unified

obsolete: speed up unstable computation Speed up the computation of the unstable revset by using the not public() revset. In another series of patches, we optimize the not public() revset and together it leads to a 50-100x speedup on the computation of unstable() for our big repos.
