log: introduce struct that carries log traversal options
I tried to refactor logcmdutil.getrevs() without using an options struct,
but none of these attempts didn't work out. Since every stage of getrevs()
needs various log command options (e.g. both matcher and revset query need
file patterns), it isn't possible to cleanly split getrevs() into a command
layer and a core logic.
So, this patch introduces a named struct to carry command options in slightly
abstracted way, which will be later used by "hg grep" and "hg churn". More
fields will be added to the walkopt struct.
Type hints aren't verified. I couldn't figure out how to teach pytype to
load its own attr type stubs in place of our .thirdparty.attr. Conditional
import didn't work. s/^from \.thirdparty // is the only way I found pytype
could parse the @attr.ib decorator.

==================================== 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 echo 'skipped: outdated artifact, md5 "'"$currenthash"'" expected "'"$expectedhash"'" run "'"$TESTDIR"'/artifacts/scripts/generate-churning-bundle.py"' 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=63327412 $ 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 : 20 ( 0.40%) lvl-2 : 68 ( 1.36%) lvl-3 : 112 ( 2.24%) lvl-4 : 180 ( 3.60%) deltas : 4618 (92.34%) revision size : 63327412 snapshot : 9886710 (15.61%) lvl-0 : 603104 ( 0.95%) lvl-1 : 1559991 ( 2.46%) lvl-2 : 2295592 ( 3.62%) lvl-3 : 2531199 ( 4.00%) lvl-4 : 2896824 ( 4.57%) deltas : 53440702 (84.39%) chunks : 5001 0x78 (x) : 5001 (100.00%) chunks size : 63327412 0x78 (x) : 63327412 (100.00%) avg chain length : 9 max chain length : 15 max chain reach : 28248745 compression ratio : 27 uncompressed data size (min/max/avg) : 346468 / 346472 / 346471 full revision size (min/max/avg) : 201008 / 201050 / 201034 inter-snapshot size (min/max/avg) : 11596 / 168150 / 24430 level-1 (min/max/avg) : 16653 / 168150 / 77999 level-2 (min/max/avg) : 12951 / 85595 / 33758 level-3 (min/max/avg) : 11608 / 43029 / 22599 level-4 (min/max/avg) : 11596 / 21632 / 16093 delta size (min/max/avg) : 10649 / 107163 / 11572 deltas against prev : 3910 (84.67%) where prev = p1 : 3910 (100.00%) where prev = p2 : 0 ( 0.00%) other : 0 ( 0.00%) deltas against p1 : 648 (14.03%) deltas against p2 : 60 ( 1.30%) deltas against other : 0 ( 0.00%)
