vfs: allow to pass more argument to audit We want to be able to do more precise check when auditing a path depending of the intend of the file access (eg read versus write). So we now pass the 'mode' value to 'audit' and update the audit function to accept them. This will be put to use in the next changeset.

zsh_completion: add '--partial' flag to completions for 'import' (issue5618) When using the 'import' command running ZSH together with its Mercurial-specific completions the flag '--partial' (introduced in Mercurial 3.1, 2014-08-01) is not offered as completion option. This patch adds it to the list of completions for the 'import' command.

configitems: register the 'bugzilla.password' config

configitems: register the 'bugzilla.mocklog' config

test-amend: fix HGEDITOR shell script to run on Windows Windows doesn't know how to launch *.sh directly. This workaround is used in several other tests.

test-paths: mask out JSON specific path differences for Windows The backslashes in the local paths were being escaped with another backslash, and $TESTTMP doesn't match against the double backslashed path. This doesn't happen without the 'json' filter.

tests: categorize entries in blacklist for fsmonitor for future reference

tests: avoid tests related to directory permission if running with fsmonitor

tests: add extra output for fsmonitor at checking under .hg

tests: add extra output for fsmonitor at showconfig

tests: take extra care for fsmonitor at enabling incompatible extension This is worthwhile, because these tests don't focus mainly on using incompatible extensions itself.

tests: remove meaningless entries from blacklist for fsmonitor IMHO, these tests were listed up in blacklist at 3b67f27bb908, because fsmonitor extension wasn't correctly installed before actual testing at that revision (this issue was fixed by 776fd2e2cf5a).

tests: remove meaningless comment from blacklist for fsmonitor These tests can run successfully since fe0667cc521e.

test-https: stabilize for Windows A leading '/' without a following drive letter is resolved to the location of the MSYS installation. These could be collapsed into a single line of output, but this seems more self documenting.

tagmerge: use workingfilectx to write merged tags This function already does an excellent job of reading from context objects; we simply need to change the single write call to eliminate all uses of the wvfs. As with past changes, the effect should be a no-op but opens the door to in-memory merge later by using different context objects.

run-tests: add color to output if pygments is available The output of run-tests has no formatting by default, which hampers readability. This patch colors the diff output when pygments is available. To avoid coloring even when pygments is available, use --color never.

win32: work around a WinError problem handling HRESULT types I ran into this ctypes bug while working with the Crypto API. While this could be an issue with any Win32 API in theory, the handful of things that we call are older functions that are unlikely to return COM errors, so I didn't retrofit this everywhere.

test-check-pyflakes: do not leave test.py in the repo Differential Revision: https://phab.mercurial-scm.org/D67

revset: add experimental ancestors/descendants relation subscript The relation name is 'generations' now, which may be changed in future.

revset: add experimental relation and subscript operators The proposed syntax [1] was originally 'set{n rel}', but it seemed slightly confusing if template is involved. On the other hand, we want to keep 'set[n]' for future extension. So this patch introduces 'set#rel[n]' ternary operator. I chose '#' just because it looks like applying an attribute. This also adds stubs for 'set[n]' and 'set#rel' operators since these syntax elements are fundamental for constructing 'set#rel[n]'.

revset: do not compute weight for integer literal argument In x^n and x~n, n isn't a set expression. There's no need to optimize the right-hand side.

templatekw: export ui.paths as {peerpaths} It's sometimes useful to show hyperlinks in log output. "{get(peerpaths, "default")}/rev/{node}" Since each path may have sub options, "{peerpaths}" is structured as a dict of dicts, but the inner dict is rendered as if it were a string URL. The implementation is ad-hoc, so there are some weird behaviors described in the test. We might need to introduce a proper way of handling a hybrid scalar object. This patch adds _hybrid.__getitem__() so d['path']['url'] works. The keyword is named as "peerpaths" since "paths" seemed too generic in log context.

summary: fix type of empty unresolved list It was okay because tested as a boolean prior to calling len(), but looked incorrect.

vfs: rename auditvfs to proxyvfs Since we've removed mustaudit property, auditvfs has no auditing business. It's just a utility class for vfs wrappers.

streamclone: comment why path auditing is disabled in generatev1() Copied from 39c6e349dfff. I wasn't sure whether it's for optimization or suppressing unwanted error.

streamclone: close large revlog files explicitly in generatev1()

bundle2: no longer use 'retractboundary' in updatephases The new 'phase-heads' forced all added node to secret before advancing the boundary to work around the fact changesets were added as draft by default. This is no longer necessary since the changegroup part can now use the 'targetphase' parameter. Not doing this retract boundary call has a couple of advantages: * This makes implementing phases change tracking in the transaction much simpler since retract boundary can become a rare case. * Bundling secret changesets is not the norm. Exchange never does that and even for strip, the use-case is not common.Skipping the retract boundary will avoid useless work here. * Sending phase update on push can be simplified since we can rely on the behavior of 'cg.apply' for most of it. This means less phases update send for example. * We no longer needs to track and use the addednodes during unbundling. This make it possible to have multiple 'changegroup' and 'phase-heads' parts in the same bundle without them interfering with each others. The new part has not been part of any release yet so we do not offer backward compatibility yet. It is important to update this semantic before the 4.3 freeze happens.

bundle2: automatically add 'targetphase' parameter in writenewbundle If we are bundling secret changeset and the bundle will contain phase, we request the changegroup to be applied as secret. It will be useful for next patch as we are now sure that secrets changesets are applied as secret and not applied as draft then forced to secret.
