util: introduce timer() As documented for timeit.default_timer, there are better timers available for performance measures on some platforms. These timers don't have a set epoch, and thus are only useful for interval measurements, but have higher resolution, and thus get you a better measurement overall. Use the same selection logic as Python's timeit.default_timer. This is a platform clock on Python 2 and early Python 3, and time.perf_counter on Python 3.3 and later (where time.perf_counter is introduced as the best timer to use).

color: move the '_render_effects' function to the core module

color: move '_effect_str' function into the core module

color: move configstyles into the core module The extension is getting thinner as we speak!

color: rework conditional 'valideffect' Not very important, but the full conditional is not that hard to follow and having it unified make the function role a bit clearer in my opinion.

color: move 'valideffect' function into the core module

color: move '_terminfo_params' into the core 'color' module On step closer to have color in core.

color: move '_effect' mapping into core This is the second things we can move into core safely.

color: spread '_effect' values for readability We move to our "usual" one value per line style.

merge with stable

update: clarify that -C and -c are mutually exclusive This makes it clear in both the synopsis and in the verbose output that -C and -c are mutually exclusive. It also restructures the verbose output a little so it's better prepared for a third option (--merge). This patch also reorders the options to match the flag table.

update: move check for dirty wdir into hg.updatetotally() The function has a "check" parameter that's currently unused, and it makes sense to me to have it honor it. That way other callers than commands.update() could set it if they needed.

destutil: drop now-unused "check" parameter from destupdate()

destutil: remove duplicate check and leave it to merge.update() The check is done in merge.update() already and the next few patches will add more checks there. Some of the additional checks will need information about the merge that will not be available in destutil. Since commands.postincoming() catches UpdateAbort(), we need to change merge.update() to raise that more specific exception. This goes directly again 45b86dbabbda (destupdate: move the check related to the "clean" logic in the function, 2015-10-05), but it will simplify the next few patches, and we can always move it out again (preferably move, not copy) after if we still think it's better that way.

ui: remove urllib2 from being imported early Before this change, urllib2 was brought in when constructing the ui object, and that added ~5ms on my Linux workstation to the hg startup time for every command, bringing the time for 'HGRCPATH=/dev/null hg root' from 46ms to 40ms. Now, we construct a single proxy object per initial ui creation (so that if the ui is copied they share the object), but defer the actual instantiation of it and the import of urllib2 until it's needed. # no-check-commit

tests: switch "this command isn't paged" example to id I'm about to enable pager support in summary.

tests: update test-i18n.t to not depend on the pager extension I'm about to mark that extension as deprecated, and that broke this test.
