==================================== 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 slow $ if [ ! -f "$bundlepath" ]; then > "$TESTDIR"/artifacts/scripts/generate-churning-bundle.py > /dev/null > fi #else $ if [ ! -f "$bundlepath" ]; then > echo 'skipped: missing artifact, run "'"$TESTDIR"'/artifacts/scripts/generate-churning-bundle.py"' > exit 80 > fi #endif $ 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 echo 'skipped: outdated artifact, md5 "'"$currenthash"'" expected "'"$expectedhash"'" run "'"$TESTDIR"'/artifacts/scripts/generate-churning-bundle.py"' 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 > revlog.reuse-external-delta = no > 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=58616973 $ 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 : 383 ( 7.66%) lvl-0 : 3 ( 0.06%) lvl-1 : 18 ( 0.36%) non-ancestor-bases: 9 (50.00%) lvl-2 : 62 ( 1.24%) non-ancestor-bases: 58 (93.55%) lvl-3 : 108 ( 2.16%) non-ancestor-bases: 108 (100.00%) lvl-4 : 191 ( 3.82%) non-ancestor-bases: 180 (94.24%) lvl-5 : 1 ( 0.02%) non-ancestor-bases: 1 (100.00%) deltas : 4618 (92.34%) revision size : 58616973 snapshot : 9247844 (15.78%) lvl-0 : 539532 ( 0.92%) lvl-1 : 1467743 ( 2.50%) lvl-2 : 1873820 ( 3.20%) lvl-3 : 2326874 ( 3.97%) lvl-4 : 3029118 ( 5.17%) lvl-5 : 10757 ( 0.02%) deltas : 49369129 (84.22%) chunks : 5001 0x28 : 5001 (100.00%) chunks size : 58616973 0x28 : 58616973 (100.00%) total-stored-content: 1 732 705 361 bytes avg chain length : 9 max chain length : 15 max chain reach : 27366701 compression ratio : 29 uncompressed data size (min/max/avg) : 346468 / 346472 / 346471 full revision size (min/max/avg) : 179288 / 180786 / 179844 inter-snapshot size (min/max/avg) : 10757 / 169507 / 22916 level-1 (min/max/avg) : 13905 / 169507 / 81541 level-2 (min/max/avg) : 10887 / 83873 / 30222 level-3 (min/max/avg) : 10911 / 43047 / 21545 level-4 (min/max/avg) : 10838 / 21390 / 15859 level-5 (min/max/avg) : 10757 / 10757 / 10757 delta size (min/max/avg) : 9672 / 108072 / 10690 deltas against prev : 3906 (84.58%) where prev = p1 : 3906 (100.00%) where prev = p2 : 0 ( 0.00%) other-ancestor : 0 ( 0.00%) unrelated : 0 ( 0.00%) deltas against p1 : 649 (14.05%) deltas against p2 : 63 ( 1.36%) deltas against ancs : 0 ( 0.00%) deltas against other : 0 ( 0.00%) Test `debug-delta-find` ----------------------- $ ls -1 SPARSE-REVLOG-TEST-FILE $ hg debugdeltachain SPARSE-REVLOG-TEST-FILE | grep snap | tail -1 4971 4970 -1 3 5 4930 snap 19179 346472 427596 1.23414 15994877 15567281 36.40652 427596 179288 1.00000 5 $ hg debug-delta-find SPARSE-REVLOG-TEST-FILE 4971 DBG-DELTAS-SEARCH: SEARCH rev=4971 DBG-DELTAS-SEARCH: ROUND #1 -
