tests: pass settings of hypothesis by with statement given(..., settings=) is no longer available in Hypothesis 2.0.0. https://github.com/DRMacIver/hypothesis/commit/7712c01

tests: adjust for code move in Hypothesis 2.0.0 It appears that the Settings class was renamed to settings, and because of this, the settings module was renamed to configuration. https://github.com/DRMacIver/hypothesis/commit/a0e663b

test-highlight: add normalization rule for Pygments 2.1 It appears that several classes have 'h', '1', '2' suffixes on Pygments 2.1, which is the current version on Debian sid.

test-highlight: factor out function that normalizes pygments output

test-highlight: unify normalization rule of pygments output We had two variants for unknown reason, s/mf/mi/g and s/mi/mf/g. This patch unifies them to s/mf/mi/g so that we can introduce a utility function.

tests: remove protected file forcibly for portability Before this patch, test-command-template.t is timed out on Solaris, because "rm" on permission denied file implies prompting "override protection 0 (yes/no)?" and blocks execution of test script.

tests: dump journal file by python script instead of sed for portability Before this patch, test-repair-strip.t fails on Solaris, because of "sed" on it doesn't work as expected if input contains null ('\0') character.

tests: execute check-config.py without xargs Before this patch, test-check-config.t fails on Solaris, because "xargs" doesn't invoke check-config.py with all filenames at once. "xargs" may invoke specified command multiple times with part of arguments given from stdin: according to "xargs(1)" man page, this dividing arguments is system-dependent. For portability of test-check-config.t, this patch adds "xargs" like mode to check-config.py and executes it in test-check-config.t without "xargs".

tests: avoid nested quoting on command line for portability Before this patch, test-revset.t fails on Solaris using ksh as default "sh", because nested quoting below isn't acceptable for it. +-----------------------------+ inner quoting "`python -c "print '|'.join(['0:1'] * 500)"`" +-------------------------------------------+ outer quoting This patch does below for portability. - omit outer quoting This should be safe, because generated string contains no white space character. - use '+' instead of '|' (for safety) '|' has special meaning for many shell, but '+' isn't (at least, for ordinary ones).

version: verbose list internal and external extension source (issue4731)

check-code: allow "grep pattern filename-containing-dash-a" We're trying to forbid "grep -a" and unintentionally complained even if the "-a" was part of the filename. Requiring a space before "-a" to match is probably good enough.

rebase: update working directory when aborting (issue5084)

revset: flatten chained 'list' operations (aka function args) (issue5072) Internal _matchfiles() function can take bunch of arguments, which would lead to a maximum recursion depth error. This patch avoids the excessive stack use by flattening 'list' nodes beforehand. Since getlist() no longer takes a nested 'list' nodes, _parsealiasdecl() also needs to flatten argument list, "aliasname($1, $2, ...)".
