perf: perform a garbage collection before each iteration
Currently, no explicit garbage collection is performed when running
the microbenchmarks in `hg perf`. I think this is wrong because
garbage collection can have a significant impact on execution times.
And, if gc is triggered via the default heuristics, it will
fire effectively randomly during subsequent benchmark iterations
due to variable amount of garbage left over from previous runs.
Running a gc before invoking the measured function will help ensure
state is more consistent across all iterations.

this structure seems to tickle a bug in bundle's search for changesets, so first we have to recreate it o 8 | | o 7 | | | o 6 |/| o | 5 | | o | 4 | | | o 3 | | | o 2 |/ o 1 | o 0 $ mkrev() > { > revno=$1 > echo "rev $revno" > echo "rev $revno" > foo.txt > hg -q ci -m"rev $revno" > } setup test repo1 $ hg init repo1 $ cd repo1 $ echo "rev 0" > foo.txt $ hg ci -Am"rev 0" adding foo.txt $ mkrev 1 rev 1 first branch $ mkrev 2 rev 2 $ mkrev 3 rev 3 back to rev 1 to create second branch $ hg up -r1 1 files updated, 0 files merged, 0 files removed, 0 files unresolved $ mkrev 4 rev 4 $ mkrev 5 rev 5 merge first branch to second branch $ hg up -C -r5 0 files updated, 0 files merged, 0 files removed, 0 files unresolved $ HGMERGE=internal:local hg merge 0 files updated, 1 files merged, 0 files removed, 0 files unresolved (branch merge, don't forget to commit) $ echo "merge rev 5, rev 3" > foo.txt $ hg ci -m"merge first branch to second branch" one more commit following the merge $ mkrev 7 rev 7 back to "second branch" to make another head $ hg up -r5 1 files updated, 0 files merged, 0 files removed, 0 files unresolved $ mkrev 8 rev 8 the story so far $ hg log -G --template "{rev}\n" @ 8 | | o 7 | | | o 6 |/| o | 5 | | o | 4 | | | o 3 | | | o 2 |/ o 1 | o 0 check that "hg outgoing" really does the right thing sanity check of outgoing: expect revs 4 5 6 7 8 $ hg clone -r3 . ../repo2 adding changesets adding manifests adding file changes added 4 changesets with 4 changes to 1 files updating to branch default 1 files updated, 0 files merged, 0 files removed, 0 files unresolved this should (and does) report 5 outgoing revisions: 4 5 6 7 8 $ hg outgoing --template "{rev}\n" ../repo2 comparing with ../repo2 searching for changes 4 5 6 7 8 test bundle (destination repo): expect 5 revisions this should bundle the same 5 revisions that outgoing reported, but it actually bundles 7 $ hg bundle foo.bundle ../repo2 searching for changes 5 changesets found test bundle (base revision): expect 5 revisions this should (and does) give exactly the same result as bundle with a destination repo... i.e. it's wrong too $ hg bundle --base 3 foo.bundle 5 changesets found $ cd ..
