inhibit: improve performance of transaction wrapping Before this patch, transaction wrapping was the most expensive part of inhibit computation wise. This patch changes the revset that we use in the transaction wrapping to make it ~50x faster to compute: revset #0: obsolete() - hidden() 0) wall 0.000214 comb 0.000000 user 0.000000 sys 0.000000 (best of 11209) vs revset #0: (not hidden()) and obsolete() 0) wall 0.010965 comb 0.010000 user 0.010000 sys 0.000000 (best of 237)

evolve: extract the code computing dependencies in a separate function The code to compute dependencies between unstable changeset can be reused to compute the next reveset. This patch extracts it in its own function to make it reusable.

directaccess: add mechanism to load directaccess after some other extensions directaccess needs to load after some extensions to avoid interfering with them. This patch adds a mechanism to specify what extension directaccess needs to load after.

evolve: add another test for evolve --rev This patch adds one test for three conditions not covered before: - evolve --rev on a stack with obsolete commits without successors - evolve --rev on two sets of stacks in parallel - evolve --rev on a set of stack partially solvable (because all of the commits of the stack are not specified with --rev)

evolve: add a more complex test for evolve --rev The previous tests of evolve --rev would have passed with an ordering of revs by increasing revision numbers. This patch adds a test that would fail if that was what we were doing and therefore tests the implementation better.

evolve: add ordering of the revisions for evolve --rev When running evolve --rev we want to process the revisions in an optimal fashion to solve the maximum amount of trouble in the minimum number of steps. This patch adds a step to evolve --rev to order the revision before solving the troubles. A simple test is added to cover a basic case.

test: adapt to change in mercurial core Bundle2 is one by default and more capability have been added.
