wireproto: don't pass transportpolicy argument The default is version 1 only. So we don't need to pass this argument when declaring commands. Differential Revision: https://phab.mercurial-scm.org/D3394

forget: rename --confirm to --interactive Differential Revision: https://phab.mercurial-scm.org/D3405

notify: add maxdiffstat option to truncate long file lists Large scale changes like a new GCC version can easily result in 1MB+ emails due to diffstat alone. The new maxdiffstat option truncates the list similar to what maxdiff already provides for the diffs. Differential Revision: https://phab.mercurial-scm.org/D3402

log: fix crash on empty revision with --copies switch If a revset is empty, .max() raises ValueError. I don't see any reason to recompute the revs, so I made it reuse the one returned by logcmdutil.getrevs(). If no revs specified by command line, the endrev will be smartset.spanset(repo) + 1, which is basically the same as len(repo), the default of getrenamedfn(). If --follow specified, revs.max() points to the working parent, which seems more correct.

revsetlang: do not pass in non-bytes to parse() Since parse() isn't a simple function, we shouldn't expect it would raise TypeError or ValueError for invalid inputs. Before, TypeError was raised at 'if pos != len(spec)', which was quite late to report an error. This patch also makes tokenize() detect invalid object before converting it to a py3-safe bytes. Spotted while adding the 'revset(...)' hack to _parsewith().

fix: use templater to substitute values in command string bytes.format() isn't supported on Python 3. Luckily, our template syntax is similar so we can reuse it. We need a hack to disable \-escapes as '\' is a directory separator on Windows.

logcmdutil: pass formatter to jsonchangeset as argument And rename the class. Now we can reuse it for 'log -Tcbor' (and '-Tpickle' if we want.)

logcmdutil: rewrite jsonchangeset printer to be backed by jsonformatter This is a bit slower than the original implementation, but I don't think that would actually matter. It's still faster than full templating. $ hg log -Tjson -r0:5000 --time > /dev/null (orig) time: real 1.550 secs (user 1.500+0.000 sys 0.040+0.000) (new) time: real 1.810 secs (user 1.740+0.000 sys 0.070+0.000) cf. $ hg log -Tdefault -r0:5000 --time > /dev/null time: real 4.980 secs (user 4.850+0.000 sys 0.130+0.000) $ hg log -r0:5000 --time > /dev/null time: real 2.340 secs (user 2.220+0.000 sys 0.100+0.000) $ hg log -r0:5000 -q --time > /dev/null time: real 0.750 secs (user 0.670+0.000 sys 0.070+0.000) The test output changes because keys are sorted alphabetically.

logcmdutil: remove unused attribute 'cache' from jsonchangeset printer Perhaps it's a copy-pasta of changeset_templater at bd15932846a4.

formatter: convert timestamp to int Spotted while porting jsonchangeset printer to formatter. A timestamp may be float type, but its meaningful part is just int.
