push: make locking of source optional (
issue3684)
Having the permission to lock the source repo on push is now optional. When the
repo cannot be locked, phase are not changed locally. A status message is issue
when some actual phase movement are skipped:
cannot lock source repo, skipping local public phase update
A debug message with the exact reason of the locking failure is issued in all
case.
push: factorise phase movement in a simple closure
Having all phases movement centralised will help to handle special case when the
local repo can not be locked as describe in issue 3684.
merge: increase safety of parallel updating/removing on icasefs
"merge.applyupdates()" sorts "actions" in removal first order, and
"workeractions" derived from it should be also sorted.
If each actions in "workeractions" are executed in serial, this
sorting ensures that merging/updating process is collision free,
because updating the file in target context is always executed after
removing the existing file which causes case-folding collision against
the former.
In the other hand, if each actions are executed in parallel, updating
on a worker process may be executed before removing on another worker
process, because "worker.partition()" partitions list of actions
regardless of type of each actions.
This patch divides "workeractions" into removing and updating, and
executes the former first.
This patch still scans "actions"/"workeractions" some times for ease
of patch review, even though large list may cost much in this way.
(total cost should be as same as before)
This also changes some tests, because dividing "workeractions" affects
progress indication.
hgweb: handle filtered "0" rev in navigation
Before this changeset, navigation generation crashed if revision "0" was
filtered. We introduce a `_first` methods on revision navigation that return the
lowest unfiltered element and use it in two place were the "0" changeset was
explicitly referenced.
Test case are introduced.
hgweb: fix empty navigation detection
For some obscure reason, changelog.node(0) returns nullid if changelog is empty.
this break empty navigation detection. We fix this code by using the length of
the changelog.
Using the length have some issue with revision filtering but this is a small
step in the right direction. Proper fix comes in later changeset.
tests: AIX can't handle negative date in test-dirstate.t
test-dirstate.t fails on AIX in the absurd date test. AIX touch errors on
any date prior to 1970. AIX mktime() gives an error on such dates, so the
problem is deeper than touch and attempts to work around touch in Python
failed.
Give up. Add an AIX test to hghave and skip the absurd date test on AIX.
