==================================== Test delta choice with sparse revlog ==================================== Sparse-revlog usually shows the most gain on Manifest. However, it is simpler to general an appropriate file, so we test with a single file instead. The goal is to observe intermediate snapshot being created. We need a large enough file. Part of the content needs to be replaced repeatedly while some of it changes rarely. $ bundlepath="$TESTDIR/artifacts/cache/big-file-churn.hg" $ expectedhash=`cat "$bundlepath".md5` $ if [ ! -f "$bundlepath" ]; then > echo 'skipped: missing artifact, run "'"$TESTDIR"'/artifacts/scripts/generate-churning-bundle.py"' > exit 80 > fi $ currenthash=`f -M "$bundlepath" | cut -d = -f 2` $ if [ "$currenthash" != "$expectedhash" ]; then > echo 'skipped: outdated artifact, md5 "'"$currenthash"'" expected "'"$expectedhash"'" run "'"$TESTDIR"'/artifacts/scripts/generate-churning-bundle.py"' > exit 80 > fi $ cat >> $HGRCPATH << EOF > [format] > sparse-revlog = yes > maxchainlen = 15 > [storage] > revlog.optimize-delta-parent-choice = yes > EOF $ hg init sparse-repo $ cd sparse-repo $ hg unbundle $bundlepath adding changesets adding manifests adding file changes added 5001 changesets with 5001 changes to 1 files (+89 heads) new changesets 9706f5af64f4:d9032adc8114 (5001 drafts) (run 'hg heads' to see heads, 'hg merge' to merge) $ hg up 1 files updated, 0 files merged, 0 files removed, 0 files unresolved updated to "d9032adc8114: commit #5000" 89 other heads for branch "default" $ hg log --stat -r 0:3 changeset: 0:9706f5af64f4 user: test date: Thu Jan 01 00:00:00 1970 +0000 summary: initial commit SPARSE-REVLOG-TEST-FILE | 10500 ++++++++++++++++++++++++++++++++++++++++++++++ 1 files changed, 10500 insertions(+), 0 deletions(-) changeset: 1:724907deaa5e user: test date: Thu Jan 01 00:00:00 1970 +0000 summary: commit #1 SPARSE-REVLOG-TEST-FILE | 1068 +++++++++++++++++++++++----------------------- 1 files changed, 534 insertions(+), 534 deletions(-) changeset: 2:62c41bce3e5d user: test date: Thu Jan 01 00:00:00 1970 +0000 summary: commit #2 SPARSE-REVLOG-TEST-FILE | 1068 +++++++++++++++++++++++----------------------- 1 files changed, 534 insertions(+), 534 deletions(-) changeset: 3:348a9cbd6959 user: test date: Thu Jan 01 00:00:00 1970 +0000 summary: commit #3 SPARSE-REVLOG-TEST-FILE | 1068 +++++++++++++++++++++++----------------------- 1 files changed, 534 insertions(+), 534 deletions(-) $ f -s .hg/store/data/*.d .hg/store/data/_s_p_a_r_s_e-_r_e_v_l_o_g-_t_e_s_t-_f_i_l_e.d: size=63002924 $ hg debugrevlog * format : 1 flags : generaldelta revisions : 5001 merges : 625 (12.50%) normal : 4376 (87.50%) revisions : 5001 empty : 0 ( 0.00%) text : 0 (100.00%) delta : 0 (100.00%) snapshot : 374 ( 7.48%) lvl-0 : 4 ( 0.08%) lvl-1 : 23 ( 0.46%) lvl-2 : 63 ( 1.26%) lvl-3 : 118 ( 2.36%) lvl-4 : 166 ( 3.32%) deltas : 4627 (92.52%) revision size : 63002924 snapshot : 9888099 (15.69%) lvl-0 : 804262 ( 1.28%) lvl-1 : 1561380 ( 2.48%) lvl-2 : 2096696 ( 3.33%) lvl-3 : 2749539 ( 4.36%) lvl-4 : 2676222 ( 4.25%) deltas : 53114825 (84.31%) chunks : 5001 0x78 (x) : 5001 (100.00%) chunks size : 63002924 0x78 (x) : 63002924 (100.00%) avg chain length : 9 max chain length : 15 max chain reach : 28907121 compression ratio : 27 uncompressed data size (min/max/avg) : 346468 / 346472 / 346471 full revision size (min/max/avg) : 201008 / 201141 / 201065 inter-snapshot size (min/max/avg) : 11601 / 157413 / 24550 level-1 (min/max/avg) : 13061 / 157413 / 67886 level-2 (min/max/avg) : 11674 / 85631 / 33280 level-3 (min/max/avg) : 11602 / 42957 / 23301 level-4 (min/max/avg) : 11601 / 21475 / 16121 delta size (min/max/avg) : 10649 / 105465 / 11479 deltas against prev : 3966 (85.71%) where prev = p1 : 3922 (98.89%) where prev = p2 : 0 ( 0.00%) other : 44 ( 1.11%) deltas against p1 : 611 (13.21%) deltas against p2 : 50 ( 1.08%) deltas against other : 0 ( 0.00%)
