copies-rust: implement PartialEqual manually
Now that we know that each (dest, rev) pair has at most a unique CopySource, we
can simplify comparison a lot.
This "simple" step buy a good share of the previous slowdown back in some case:

============================= Test distributed obsolescence ============================= This file test various cases where data (changeset, phase, obsmarkers) is added to the repository in a specific order. Usually, this order is unlikely to happen in the local case but can easily happen in the distributed case. $ unset HGUSER $ unset EMAIL $ . $TESTDIR/testlib/obsmarker-common.sh $ cat >> $HGRCPATH << EOF > [extensions] > rebase = > [experimental] > evolution = all > [phases] > publish = False > [command-templates] > log = {rev}:{node|short} {desc}{if(obsfate, " [{join(obsfate, "; ")}]")}\n > EOF Check distributed chain building ================================ Test case where a changeset is marked as a successor of another local changeset while the successor has already been obsoleted remotely. The chain of evolution should seamlessly connect and all but the new version (created remotely) should be seen as obsolete.

Check getting changesets after getting the markers ================================================= This test case covers the scenario where commits are received -after- we received some obsolescence markers turning them obsolete. For example, we pull some successors from a repository (with associated predecessors marker chain) and then later we pull some intermediate precedessors changeset from another repository. Obsolescence markers must apply to the intermediate changeset. They have to be obsolete (and hidden). Avoiding pulling the changeset in the first place is a tricky decision because there could be non-obsolete ancestors that need to be pulled, but the discovery cannot currently find these (this is not the case in this tests). In addition, we could also have to pull the changeset because they have children. In this case, they would not be hidden (yet) because of the orphan descendant, but they would still have to be obsolete. (This is not tested in this case either). $ mkdir distributed-chain-building $ cd distributed-chain-building $ hg init server $ cd server $ cat << EOF >> .hg/hgrc > [ui] > username = server > EOF $ mkcommit ROOT $ cd .. $ hg clone server repo-Alice updating to branch default 1 files updated, 0 files merged, 0 files removed, 0 files unresolved $ cat << EOF >> repo-Alice/.hg/hgrc > [ui] > username = alice > EOF $ hg clone server repo-Bob updating to branch default 1 files updated, 0 files merged, 0 files removed, 0 files unresolved $ cat << EOF >> repo-Bob/.hg/hgrc > [ui] > username = bob > EOF $ hg clone server repo-Celeste updating to branch default 1 files updated, 0 files merged, 0 files removed, 0 files unresolved $ cat << EOF >> repo-Celeste/.hg/hgrc > [ui] > username = celeste > EOF Create some changesets locally $ cd repo-Alice $ mkcommit c_A0 $ mkcommit c_B0 $ cd ..
