revert: split between newly added file and file added in other changeset These two kinds of files are handled differently. One is deleted and the other is just forgotten (the file is untracked but left in place). The distinction is done in the `_performrevert` code itself and we would like to get ride of this.

revset: stop using a baseset instead of a plain list in _revsbetween The function internal code needs a list. Lets use a list.

run-tests: added 'cuser', 'csys' time info in report.json file This patch adds up a 'cuser' and 'csys'(cputime) info in report.json file which generated when --json is enabled while testing. Now the new format of report.json file is as below. testreport ={ "test-success.t": { "csys": "1.041", "cuser": "1.041", "result": "success", "time": "2.041" } "test-failure.t": { "csys": "1.041", "cuser": "1.041", "result": "failure", "time": "4.430" } "test-skip.t": { "csys": "1.041", "cuser": "1.041", "result": "skip", "time": "3.754" } }

import: let --exact 'work' with --no-commit (issue4376)

obsolete: use C code for headrevs calculation Previously, if there were filtered revs the repository could not use the C fast path for computing the head revs in the changelog. This slowed down many operations in large repositories. This adds the ability to filter revs to the C fast path. This speeds up histedit on repositories with filtered revs by 30% (13s to 9s). This could be improved further by sorting the filtered revs and walking the sorted list while we walk the changelog, but even this initial version that just calls __contains__ is still massively faster. The new C api is compatible for both new and old python clients, and the new python client can call both new and old C apis.

revset: simplify orderedlazyset creation in spanset method We can simply use the `self.isascending` value instead of more complex if/else clause. This get the code simpler. Benchmarks show no performances harmed in the process.

revset: use spanset.isdescending in multiple simple places We call the method directly instead of duplicating checks. Benchmarks show no performances harmed in the process.

revset: wider definition of ascending and descending for spanset Before this patches, empty spanset were seen as neither ascending nor descending. This is mathematically wrong and create some edges case. We put `isascending` and `isdescending` back on track so we can use them to simplify some of the spanset code. Benchmarks show no performances harmed in the process.

annotate: port to generic templater enabled by hidden -T option If the selected formatter is other than plainformatter, raw data are passed to the formatter. In this case, it isn't necessary (and not possible) to calculate column widths. Field names are substituted to be the same as "log" command. There are a few limitations: - "binary file" message is not included in formatted output. - no data structure for multiple files. all lines are packed to single list.

annotate: split functions to get data without applying text formatting This prepares for porting to generic templater API, where raw data should be passed to the formatter. makefunc() is necessary to build closure in list comprehension.
