hgweb: fail if an invalid command was supplied in url path (issue4071) Traditionally, the way to specify a command for hgweb was to use url query arguments (e.g. "?cmd=batch"). If the command is unknown to hgweb, it gives an error (e.g. "400 no such method: badcmd"). But there's also another way to specify a command: as a url path fragment (e.g. "/graph"). Before, hgweb was made forgiving (looks like it was made in 44c5157474e7) and user could put any unknown command in the url. If hgweb couldn't understand it, it would just silently fall back to the default command, which depends on the actual style (e.g. for paper it's shortlog, for monoblue it's summary). This was inconsistent and was breaking some tools that rely on http status codes (as noted in the issue4071). So this patch changes that behavior to the more consistent one, i.e. hgweb will now return "400 no such method: badcmd". So if some tool was relying on having an invalid command return http status code 200 and also have some information, then it will stop working. That is, if somebody typed foobar when they really meant shortlog (and the user was lucky enough to choose a style where the default command is shortlog too), that fact will now be revealed. Code-wise, the changed if block is only relevant when there's no "?cmd" query parameter (i.e. only when command is specified as a url path fragment), and looks like the removed else branch was there only for falling back to default command. With that removed, the rest of the code works as expected: it looks at the command, and if it's not known, raises a proper ErrorResponse exception with an appropriate message. Evidently, there were no tests that required the old behavior. But, frankly, I don't know any way to tell if anyone actually exploited such forgiving behavior in some in-house tool.

keepalive: fix how md5 is used The code in keepalive dates from when it was importing the md5 module directly and uses md5.new. Since then, what 'md5' means has been changed from an import of the md5 module to being a function using the right module between hashlib and md5, so the md5.new idiom doesn't work anymore.

revset: add an optimised baseset.__contains__ (issue4371) The baseset class is based on a python list. This means that base.__contains__ was absolutely as crappy as list.__contains__. We now rely on __contains__ from the underlying set. This will avoid having to explicitly convert the baseset to a set (using baseset.set()) whenever one want fast membership test. Apparently there is already code that forgot to do such conversions since we observe a massive speedup in some test. revset #25: roots((0::) - (0::tip)) 0) wall 2.079454 comb 2.080000 user 2.080000 sys 0.000000 (best of 5) 1) wall 0.132970 comb 0.130000 user 0.130000 sys 0.000000 (best of 65) No regression is observed in benchmarks. This change improve the issue4371 back to acceptable situation (but are still slower than manual substraction)

commands: deprecate the parents commands It's replaced by 'hg summary' or hg log -r 'parents(foo)' and doesn't need to take up space in our command list anymore.

revset: remove nullrev from the bookmark computation Same as for other revset we sanitize the content of the set to be able to rely on it more.

revset: unify code flow in `bookmark` We refactor the code of the bookmark revset to have a single return. This will allow us to sanitize the content of the set.

revset: remove invalid value in the origin set Same as the parents related revsets, origin had some invalid value in the computed set. We remove them.

revset: remove nullrev from set computed in parents() The old code relied on the subset contents to get rid of invalid values. We would like to be able to rely more on the computation in parents() so we filter out the invalid value.

revset: refactor parents() into a single return point Both paths are doing similar thing in the end. We refactor the function so that the `ps` set is commonly used at the end. This will end excluding `nullrev` from this set in a future patch

revset: remove nullrev from set computed in p1() and p2() The old code relied on the subset contents to get rid of invalid values. We would like to be able to rely more on the computation in p1() and p2() so we filter out the invalid value

revset: document the choice made in __generatorset.__iter__ The method code looks a bit ugly but has good reasons to. We document them to prevent naive refactoring in the future.

help: mention mode in hg log --removed help (issue4381)

commit: catch changed exec bit on files from p1 (issue4382)

revert: add a `drop` action This prevents the need for a try except in the `_performrevert` code.

revert: explicitly track added but deleted file Added + deleted file are files that need to be untracked from the dirstate but that are already missing on disk. The current `_performrevert` code is handling that with exception catching. We will be able to do better with a dedicated set.

revert: have an explicit action for "forget" The distinction between "remove" and "forget" used to be in special logic checking for the state of the file in the dirstate. Now that we have dedicated filtering, we can stop relying on this logic and have two distinct actions.

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.

annotate: remove unused variable in calculation of column widths

annotate: build format string separately from annotation data This prepares for porting to generic templater API. Note that we cannot use '%*s' to pad white spaces because it doesn't take into account character widths, as described in 4f5a6df2af92.
