tests: use 'do sleep 0' instead of 'do true', also on first line of command f64b25f147d7 established that '... do true ...' shouldn't be used, but that was only enforced on continued lines.

check-code: put grouping around regexps generated from testpats This removes the pitfall that would make the testpath r'a|b' match 'b' on all lines in .t tests.

tests: don't use /dev/urandom for largefiles testing There is no need to use entropy here just to create some content that only will be used for hashing and ignored. This avoids a problem where dd from /dev/urandom on solaris generates too short output.

encoding: protect against non-ascii default encoding If the default python encoding was changed from ascii, the attempt to encode as ascii before lower() could throw a UnicodeEncodeError. Catch UnicodeError instead to prevent an unhandled exception.

update: fix case-collision with a clean wd and no --clean cbf2ea2f5ca1 introduced some logic to avoid case-collision detection between source and destination revisions when it does not make sense: clean or to be cleaned working directories. Unfortunately, part of it was flawed and the related test was broken by another bug. This patch disables cross revision case collision detection for updates without option or with --check, if the working directory is clean.

update: make --check abort with dirty subrepos Aka "we could use dirty() but... yeah let's use it"

update: fix "not rev" vs "rev is None"

plan9: add missing source entries to proto

Merge stable

tests: fix incorrect markup of continued lines of sh commands

check-code: 'printf \0' is apparently fine - accept it in check-code Nobody complained over '\0' in test-eol.t. The too strict check becomes a problem when this check is applied to more lines.

tests: solaris sh can not negate exit status with '!'

tests: hide diff -u saying 'No differences encountered' on solaris

tests: ^ must be quoted when used on solaris sh The check was broken when it was introduced in 6e4cf8319f54.

tests: remove test-pull-pull-corruption2.t This test gave random failures on slow machines (solaris). The test was added in 6f6e210b38cf as a test case from issue148. It did however require manual setup: The attached script creates such a corruption (you have to add a "import time; time.spleep(3)" in localrepo.addchangegroup before the changegroup manifest are written for example. The test as it is has thus no value as automatic test case. The necessary sleep could be added by a hook, but test-pending.t already tests that.

tests: remove race in test-pull-pull-corruption.t The output from the background process was not always interleaved "correctly" with output from the foreground process.
