run-tests: defer leftover (?) cleanup until after all output is exhausted Previously, after matching a single line, any contiguous subsequent lines ending with (?) would be added to the output and removed from the expected output. This is a problem if the subsequent test output would have matched the consumed (?) line, because it kept the optional line and then added a duplicate without the (?) [1]. Instead, wait until there is nothing more to match before handling the leftovers. [1] https://www.mercurial-scm.org/pipermail/mercurial-devel/2016-February/080197.html

test-run-tests: pad the failure test to preserve the run order Test size seems to dictate the order in which the tests are run, and the next patch will add to test-success.t.

changelog: backed out changeset 86de91c56355

changelog: backed out changeset 1778770e1982 We want to avoid leaking UTF-8 to main body of code wherever possible.

dispatch: store norepo/optionalrepo/inferrepo attributes in function (API) This can eliminate import cycles and ugly push/pop of global variables at _checkshellalias(). Attributes of aliascmd are directly accessible. Because norepo/optionalrepo/inferrepo lists aren't populated, extensions examining them no longer work. That's why this patch removes these lists to signal the API incompatibility. This breaks 3rd-party extensions that are yet to be ported to @command decorator.

extensions: copy extra __dict__ of original function Future patches will make @command decorator set properties such as "norepo" to a function object. This patch makes sure these properties never be lost by wrapcommand() or wrapfunction(). This change won't be crazy as the standard functools.wraps() copies __dict__.

extensions: copy attributes to wrapper by wrapfunction() Before this patch, new partial function "wrap" had no useful docstring. It makes sense to copy __doc__ and __module__ as we do for wrapcommand().

extensions: extract function that copies function attributes to wrapper wrapfunction() will be changed to copy these attributes. See the next patch for details.

tests: fix section description Copy and paste error

zeroconf: import ui as uimod per test-check-module-imports

changelog: lazy decode user (API) This appears to show a similar speedup as the previous patch.

changelog: lazy decode description (API) Currently, changelog reading decodes read values. This is wasteful because a lot of times consumers aren't interested in some of these values. This patch changes description decoding to occur in changectx as needed. revsets reading changelog entries appear to speed up slightly: revset #7: author(lmoscovicz) plain 0) 0.906329 1) 0.872653 revset #8: author(mpm) plain 0) 0.903478 1) 0.878037 revset #9: author(lmoscovicz) or author(mpm) plain 0) 1.817855 1) 1.778680 revset #10: author(mpm) or author(lmoscovicz) plain 0) 1.837052 1) 1.764568

blackbox: optionally log event source

blackbox: remove hexfn It was introduced as copy+paste code, but was never necessary.

blackbox: rewrite dirty documentation noting it is expensive
