resourceutil: account for the non-resource-like file hierarchy under py2exe
After 9e367157a990, config files for py2exe were expected to be in
C:\Program Files\Mercurial\mercurial\defaultrc because of the implied resource
structure of 'mercurial.defaultrc.*.rc', relative to the executable.
Accomodating this would require changes to the WIX and Inno scripts (and perhaps
the script that generates the WIX script), as well as 3rd party bundlers like
TortoiseHg. But these files aren't read as resources anyway- they fall back to
the filesystem APIs. (If we really wanted to carry on the charade, the
installer would have to also sprinkle various empty __init__.py files around.)
Instead, this simply prunes the 'mercurial.' portion of the resource name when
run with py2exe. (PyOxidizer uses the resources API, not the filesystem
fallback, so it is unaffected.) Since this hack only affects the py2 Windows
installers and is less risky, I think it's reasonable. We haven't needed to
load any 3rd party resource up to this point, and would have to make packaging
changes anyway to handle that.

==================================== 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 echo 'skipped: outdated artifact, md5 "'"$currenthash"'" expected "'"$expectedhash"'" run "'"$TESTDIR"'/artifacts/scripts/generate-churning-bundle.py"' 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%)
