phabricator: warn if unable to amend, instead of aborting after posting
There was a divergence in behavior here between obsolete and strip based
amending. I first noticed the abort when testing outside of the test harness,
but then had trouble recreating it here after reverting the code changes. It
turns out, strip based amend was successfully amending the public commit after
it was posted! It looks like the protection is in the `commit --amend` command,
not in the underlying code that it calls.
I considered doing a preflight check and aborting. But the locks are only
acquired at the end, if amending, and this is too large a section of code to be
wrapped in a maybe-it's-held-or-not context manager for my tastes.
Additionally, some people do post-push reviews, and amending is the default
behavior, so they shouldn't see a misleading error message.
The lack of a 'Differential Revision' entry in the commit message breaks a
{phabreview} test, so it had to be partially conditionalized.

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 echo 'skipped: outdated artifact, md5 "'"$currenthash"'" expected "'"$expectedhash"'" run "'"$TESTDIR"'/artifacts/scripts/generate-churning-bundle.py"' 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