tests: inform on Windows about unnecessary glob lines When glob lines directly match on windows, "/" (and not "\") was output in the path on the line. No glob matching is necessary in this case. The test output will look like this (when 5 tests have passed and no 4 has an unnecessary glob): ... Info, unnecessary glob: info about some/thing (glob) .. [ original upstream message ]

tests: quickly check if the glob line already matches the output This happens when a path with "/" as only glob char is matched on a non windows platform. (Currently one third of all glob matches.) The slowdown on windows and the speedup on other os are neglectable. [ original upstream message ]

export: show 'Date' header in a format that also is readable for humans 'export' is the official export format and used by patchbomb, but it would only show date as a timestamp that most humans might find it hard to relate to. It would be very convenient when reviewing a patch to be able to see what timestamp the patch will end up with. Mercurial has always used util.parsedate for parsing these headers. It can handle 'all' date formats, so we could just as well use a readable one. 'export' will now use the format used by 'log' - which is the format described as 'Unix date format' in the templating help. We assume that all parsers of '# HG changeset patch'es can handle that.

run-tests.py: don't let hg run interactively in debug mode In normal test mode stdin is closed and hg is thus not interactive. In --debug mode stdin is inherited from the running console and to the tests, and hg could thus wait in prompts when running on Windows. See http://selenic.com/pipermail/mercurial-devel/2013-January/047548.html . Instead set ui.interactive=False to make Mercurial non-interactive. Other commands might still work differently in the --debug environment. This should solve the problem with hg waiting for input but still make it possible to add --debugger to hg in a test and run run-tests.py with --debug. [ original upstream message ]

run-tests.py: backout "don't use console for stdin when running in debug mode" f5842787a958 caused that some kind of interactive debugging no longer was possible - such as running hg with --debugger in a test run with run-tests.py --debug . [ original upstream message ]

destroyed: drop complex branchcache rebuilt logic The strip code used a trick to lower the cost of branchcache update after a strip. However is less necessary since we have branchcache collaboration. Invalid branchcache are likely to be cheaply rebuilt again a near subset of the repo. Moreover, this trick would need update to be relevant in the now filtered repository world. It currently update the unfiltered branchcache that few people cares about. Make it smarter on that aspect would need complexes update of the calling logic So this mechanism is: - Arguably needed, - Currently irrelevant, - Hard to update and I'm dropping it. We now update the branchcache in all case by courtesy of the read only reader. This changeset have a few expected impact on the testsuite are different cache are updated. [ original upstream message ]

branchmap: update cache of 'unserved' filter on new changesets The `commitctx` and `addchangegroup` methods of repo upgrade branchcache after completion. This behavior aims to keep the branchcache in sync for read only process as hgweb. See ee317dbfb9d0 for details. Since changelog filtering is used, those calls only update the cache for unfiltered repo. One of no interest for typical read only process like hgweb. Note: By chance in basic case, `repo.unfiltered() == repo.filtered('unserved')` This changesets have the "unserved" cache updated instead. I think this is the only cache that matter for hgweb. We could imagine updating all possible branchcaches instead but: - I'm not sure it would have any benefit impact. It may even increase the odd of all cache being invalidated. - This is more complicated change. So I'm going for updating a single cache only which is already better that updating a cache nobody cares about. This changeset have a few expected impact on the testsuite are different cache are updated. [ original upstream message ]

tests: run with PYTHONHASHSEED=random Python set and dict iteration order is in principle undefined but usually 'quite stable'.

filtering: rename filters to their antonyms Now that changelog filtering is in place, it's become evident that naming the filters according to the set of revs _not_ included in the filtered changelog is confusing. This is especially evident in the collaborative branch cache scheme.

The mechanism for finding the right name (python or python.exe) also had to be simplified and made more explicit. [ original upstream message ]

branchmap: allow to use cache of subset Filtered repository are *subset* of unfiltered repository. This means that a filtered branchmap could be use to compute the unfiltered version. And filtered version happen to be subset of each other: - "all() - unserved()" is a subset of "all() - hidden()" - "all() - hidden()" is a subset of "all()" This means that branchmap with "unfiltered" filter can be used as a base for "hidden" branchmap that itself could be used as a base for unfiltered branchmap. unserved < hidden < None This changeset implements this mechanism. If the on disk branchcache is not valid we use the branchcache of the nearest subset as base instead of computing it from scratch. Such fallback can be cascaded multiple time is necessary. Note that both "hidden" and "unserved" set are a bit volatile. We will add more stable filtering in next changesets. This changeset enables collaboration between no filtering and "unserved" filtering. Fixing performance regression introduced by 47f00b0de337 [ original upstream message ]

localrepo: filter unknown nodes from the phasecache on destroyed When commit is followed by strip (qrefresh), phasecache contains nodes that were removed from the changelog. Since phasecache is filecached with .hg/store/phaseroots which doesn't change as a result of stripping, we have to filter it manually. If we don't write it immediately, the next time it is read from disk the nodes will be filtered again. That's what happened before, but there's no reason not to write it immediately. The change in test-keyword.t is caused by the above. [ original upstream message ]

test-http-branchmap: enable on Windows Tests using "hg serve --daemon" are currently disabled on Windows for lack of proper kill utility. The one shipped with MinGW operates on internal process identifiers and not on the ones recorded by hg serve. Fortunately we can replace most of them by calls to killdaemons.py. This patch is a proof of concept on how to run these tests on Windows. The plan is: - Check test-http-branchmap.t does not fail/hang on the buildbot - Convert all kill utility calls to killdaemons.py calls. - Add a rule in check-code.py to forbid kill calls, or ignore the remaining ones (test-hup.t, etc.). - Possibly drop the 'serve' rule from hghave. The: listening at http://*:$HGPORT1/ line does not appear on Windows because the detached process can no longer write on its parent streams. Grepping hg serve stdout directly causes the parent process to never return and hangs the test. This is a bug, but I have no simple solution and prefer to pay this small price and enable hg serve tests on Windows. [ orginal upstream message ]

record: allow splitting of hunks by manually editing patches It is possible that unrelated changes in a file are on sequential lines. The current record extension does not allow these to be committed independently. An example use case for this is in software development for deeply embedded real-time systems. In these environments, it is not always possible to use a debugger (due to time-constraints) and hence inline UART-based printing is often used. When fixing a bug in a module, it is often convenient to add a large number of 'printf's (linked to the UART via a custom fputc) to the module in order to work out what is going wrong. printf is a very slow function (and also variadic so somewhat frowned upon by the MISRA standard) and hence it is highly undesirable to commit these lines to the repository. If only a partial fix is implemented, however, it is desirable to commit the fix without deleting all of the printf lines. This is also simplifies removal of the printf lines as once the final fix is committed, 'hg revert' does the rest. It is likely that the printf lines will be very near the actual fix, so being able to split the hunk is very useful in this case. There were two alternatives I considered for the user interface. One was to manually edit the patch, the other to allow a hunk to be split into individual lines for consideration. The latter option would require a significant refactor of the record module and is less flexible. While the former is potentially more complicated to use, this is a feature that is likely to only be used in certain exceptional cases (such as the use case proposed above) and hence I felt that the complexity would not be a considerable issue. I've also written a follow-up patch that refactors the 'prompt' code to base everything on the choices variable. This tidies up and clarifies the code a bit (removes constructs like 'if ret == 7' and removes the 'e' option from the file scope options as it's not relevant there. It's not really a necessity, so I've excluded it from this submission for now, but I can send it separately if there's a desire and it's on bitbucket (see below) in the meantime. Possible future improvements include: * Tidying up the 'prompt' code to base everything on the choices variable. This would allow entries to be removed from the prompt as currently 'e' is offered even for entire file patches, which is currently unsupported. * Allowing the entire file (or even multi-file) patch to be edited manually: this would require quite a large refactor without much benefit, so I decided to exclude it from the initial submission. * Allow the option to retry if a patch fails to apply (this is what Git does). This would require quite a bit of refactoring given the current 'hg record' implementation, so it's debatable whether it's worth it. Output is similar to existing record user interface except that an additional option ('e') exists to allow manual editing of the patch. This opens the user's configured editor with the patch. A comment is added to the bottom of the patch explaining what to do (based on Git's one). A large proportion of the changeset is test-case changes to update the options reported by record (Ynesfdaq? instead of Ynsfdaq?). Functional changes are in record.py and there are some new test cases in test-record.t. [ original upstream message ]

mq: restore _branchtags() fast path (issue3223) Since a5917346c72e, mq saves the nodeid of the first applied patch to cache/branchheads, which breaks the optimized cache handling introduced in fbf8320f25c8. The problem is the revision being committed is appended to mqrepo.applied after the commit succeeds, which means mqrepo._branchtags() performs a regular update and write the first applied patch to the branch cache. One solution is to set a context variable _committingpatch on the mqrepo while it is committing a patch and to take it in account when deciding to fast-path mqrepo._branchtags(). Not really elegant but it works. The changes to test-mq-caches.t reverse changes introduced by a5917346c72e. The cache should not have been updated with mq records. The changes to test-keyword.t are indirectly caused by a5917346c72e. Reported and analyzed by Yuya Nishihara <yuya@tcha.org> Notes: - qpush still makes a slow path _branchtags() call when checking heads. Maybe this can be optimized. - be careful when merging this patch in default as secretcommit() was renamed newcommit() right after the end of the code freeze. [ original upstream message ]

tests: tighten checks for octal escapes in shell printf. printf on AIX default shell ksh (89) says \1 is an invalid escape. It insists on at least 2 digits. This causes failures in test-keyword.t and test-status.t. check-code.py already looks out for \NNN and recommends using Python for outputting octal values. Extend the check to \NN and \N and fix up resulting failures. [ original upstream message ]

run-tests: expand user in --with-hg This makes it possible to run: $ ./run-tests.py --with-hg=~/hg-bin/hg [ original upstream message ]

tests: let run-tests.py default to use 'sh' in $PATH instead of '/bin/sh' This makes it easier to run tests on systems that have a usable sh in the search path but not in the standard location. [ original upstream message ]

tests: add 'set -x' to the .t sh scripts in run-tests.py debug mode This makes -d output much more readable when debugging the test framework or very strange test failures. [ original upstream message ]
