obsolescence: add test for the "branch replacement" logic during push, case B6 Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This changeset adds test for the improved "branch replacement" logic introduce in an earlier commits. This tests initially lived in the evolve extensions. Since we now have the code handling this logic in core, it make sense to have the tests in core too. See inline documentation for details about the test case added in this changeset.

checkheads: upgrade the obsolescence postprocessing logic (issue4354) The previous logic had many shortcoming (eg: looking at the head only, not handling prune, etc...), the new logic use a more robust approach: For each head, we check if after the push all changesets exclusive to this heads will be obsolete. If they are, the branch considered be "replaced". To check if a changeset will be obsolete, we simply checks: * the changeset phase * the existence of a marker relevant to the "pushed set" that affects the changesets.. This fixes two major issues of the previous algorithm: * branch partially rewritten (eg: head but not root) are no longer detected as replaced, * Prune are now properly handled. (This implementation was introduction in the evolve extension, version 6.0.0.) This new algorithm has an extended number of tests, a basic one is provided in this patch. The others will be introduced in their own changeset for clarity. In addition, we stop trying to process heads unknown locally, we do not have enough data to take an informed decision so we should stop pretending we do. This reflect a test that is now update.

test-http: add a (glob) for Windows I'm not sure why the glob was ineffective with $TESTTMP here, but replacing it with '*' works.

testlib: move the prune alias into a shell script for Windows Cramming all of this directly into an alias doesn't play nicely on Windows. Various test-exchange-obsmarkers-case-XX.t were failing with: abort: cannot select revision when creating marker It turned out that inside debugcommands.debugobsolete(), the following differed from Linux (where they were empty, at least in the case I debugged): 'rev': ['.`;'], 'template': "'{node}\\n'"

hidden: extract the code generating "filtered rev" error for wrapping The goal is to help experimentation in extensions (ie: evolve) around more advance messages.
