urlutil: introduce a new `list_paths` function This function will be useful for command and template that wants to display path related information. Differential Revision: https://phab.mercurial-scm.org/D10440

urlutil: deprecate `getpath` There as no remaining user of that function. Differential Revision: https://phab.mercurial-scm.org/D10439

urlutil: inline the relevant part of `getpath` in `get_push_paths` The part that `get_push_paths` needs is quite simple, inclining will help us to deprecated `getpath`. Differential Revision: https://phab.mercurial-scm.org/D10438

url_util: introduce a `try_path` function That function… try a build a path, returning None on failure. This helps us to simplify various part of the existing code. Differential Revision: https://phab.mercurial-scm.org/D10437

narrow: add more status messages when narrowing Each of the steps I added status messages for in this patch frequently take minutes or tens of minutes for our internal users. It would be nice to also have a progress bar but that will have to come later. Differential Revision: https://phab.mercurial-scm.org/D10503

narrow: add progress-reporting when looking for local changes in `hg tracked` Looking for local changes (changes not on the given remote) can take a long time, so we should have progress-reporting for it. Differential Revision: https://phab.mercurial-scm.org/D10501

chg: pass --no-profile to disable profiling when starting hg serve If profiling is enabled via global/user config (as far as I can tell, this doesn't affect use of the --profile flag, but it probably does affect --config profiling.enabled=1), then the profiling data can be *cumulative* for the lifetime of the chg process. This leads to some "interesting" results where hg claims the walltime is something like 200s on a command that took only a second or two to run. Worse, however, is that with at least some profilers (such as the default "stat" profiler), this can cause a large slowdown while generating the profiler output.

profiling: add --no-profile to disable profiling enabled via config Differential Revision: https://phab.mercurial-scm.org/D10469

tests: fix test-chg to ignore a warning about being unable to set locale This is apparently coming from bash when bash is providing the sh that we're using to execute the .sh file generated by run-tests for this test.

branch: delete obsolete message about changing branch of obsolete commit We now rely on `rewriteutil.precheck()` to check for divergence, so we don't need the extra check in `cmdutil.changebranch()`. The former check is a little less strict in that it allows you to rewrite a commit without non-obsolete successors. Differential Revision: https://phab.mercurial-scm.org/D10519
