revset: add helper to build balanced addsets from chained 'or' operations This function will be used by revset.orset() and scmutil.revrange() to reduce the stack depth from O(n) to O(log(n)). We've bikeshed the interface of this function, but we couldn't come to an agreement. So we decided to attempt to make it move forward. marmoute: - new factory function isn't necessary for balanced addsets - addset.__init__ can just recurse, should handle "len(subsets) == 2+" yuja: - want to write all "len(subsets) == 0, 1, 2, 3+" cases in the same function - no recursion in __init__ for cosmetic reason: can't return, can't call __init__ directly I've changed it to a private function so that nobody would be tempted to utilize it.

revset: comment that we can't swap 'or' operands by weight Though the original code did nothing, it tried to optimize the calculation order by weight. But we can't simply swap 'ta' and 'tb' because it would change the order of revisions. For future reference, this patch keeps the modified version of the original code as comment.

parser: add helper to reduce nesting of chained infix operations This will be used to avoid stack overflow caused by chained 'or' operations in revset.

convert: properly pass null ids through .hgtags (issue4678) Mercurial uses tags of null to mark deletions, but convert was silently discarding these because it had no mapping for them. Thus, it was resurrecting deleted tags.

commit: improve --close-branch documentation The confusion about whether this flag closes a whole branch or just a head comes up regularly on IRC, so add some clarification.

patch: add 'extra' argument to makememctx The uncommit command in evolve needs to create memory context with given extra parameters. This patch allows us to do that instead of always giving them an empty value and having to override it afterwards.

repair: forbid strip from inside a transaction Stripping inside a transaction will (at best) crash or (at worst) result in very unexpected results. We explicitly forbid it early.
