changegroup: introduce an explicit linear sorting We still need to linearize the revisions in some cases, introduce an explicit `linear` sorting before changing back the default order. Differential Revision: https://phab.mercurial-scm.org/D5195

py3: roll up threading.Thread constructor args into **kwargs The constructor doesn't have a `verbose` keyword argument in py3.

tests: glob over a single quote vs double quote difference on Windows

py3: port test-log-exthook.t to Python 3 For once an easy one. Differential Revision: https://phab.mercurial-scm.org/D5184

extensions: fix up many many debug logs that use %r This gets us a bunch closer on Python 3, but I'll still have to use a ton of sad globs. A previous version of this patch tried to preserve the %r formatting, but upon review Yuya noted that special characters in extension names is very unlikely, so we can just use %s and not sweat the quoting.

blackbox: add configitem for format of log timestamps Sometimes blackbox logs are used to report performance problems, but the timestamps are only at second granularity, so often the timings have to stated separately by the reporter. This is inconvenient and error-prone, so I would like to include %f in the date format. This patch makes that possible.

narrow: replace filtering in list comprehension by set operations I didn't think of this while reviewing the patch. Differential Revision: https://phab.mercurial-scm.org/D5188

storage: update sqlitestore to use the new `deltamode` parameter While updating the filelog class, I forget to update the sqlitestore, tests are now passing with this patch. Differential Revision: https://phab.mercurial-scm.org/D5185

narrow: rework logic to check whether we need to widen and narrow This patch reworks logic which calculates whether we need to extend or narrow our working copy or not. We filter the addincludes, removeincludes, addexcludes and removeexcludes passed from user to the actual added and removed includes and excludes. What that means is a user can pass an already included path as addincludes, a path which is not included as removeincludes etc. In such situations the old logic use to think we need to do some work, whereas we don't need to do that work. In old logic, even if we don't have anything new to include but it believes we need to call widen, this adds some good amount of work on large repository. A widen calls involves computing incomming csets, calling the narrow_widen() which in non-ellipses cases goes through all the set of csets which are available which can take ~2-3 mins on large repos. Those 2-3 minutes are spend on doing nothing which a client can prevent by checking is there really anything which needs to be included. The tests changes shows that we don't go to the server anymore in such cases which is nice. Differential Revision: https://phab.mercurial-scm.org/D5183

tests: show that adding an already included path still calls narrow_widen() This patch adds tests demonstrating that we still go to the server in non-ellipses widening when we have that path already on the client and there is nothing new to download. The next patch will try to make client side logic smart and not go to the server if we don't need to download anything. Differential Revision: https://phab.mercurial-scm.org/D5182
