tests: avoid referring to pvec in demandimport test Nothing else currently uses pvec, so we may want to delete it (but Augie Fackler says he may want to use it). To enable deletion, this patch replaces it by the error module in the demandimport test (any module works). However, since the error module had already been loaded at this point in the test (via the util module), I moved it earlier in the test so it's still not loaded (although I'm not sure if that's even relevant to the test).

cmdutil: narrow scope of KeyError in makefilename() It seemed too broad to catch a standard Python exception.

node: make bin() be a wrapper instead of just an alias This includes a full backout of 59affe7e and 30d0cb27. Per the review of the former, we'd rather adapt the API to behave like it used to (at least for now), and take a second run at it if it shows up in our performance numbers. I ran perfrevlogindex with and without this change and it didn't make a measurable difference, so maybe it's fine (despite my intuition to the contrary).

tests: actually check that HGDEMANDIMPORT=disable disables demandimport At the point in the test where we were checking that the 'node' got eagerly loaded, it had already been loaded (via the pvec module), so our check wasn't doing anything (i.e. the test would pass even if you removed the line that set HGDEMANDIMPORT=disable). Let's move this test earlier so it tests what it was meant to test. Differential Revision: https://phab.mercurial-scm.org/D2286

debugcommands: print out the editor that was searched for (post shlexsplit) A user was in #mercurial and had the following settings in their hgrc: [ui] editor = C:\home\npp\notepad++.exe -multiInst -nosession After shlexsplit, the first argument was mangled into C:homenppnotepad++.exe, which was quite unlikely to exist. It took many back-and-forths to identify that adding " characters around the exe would fix the issue; we were thinking that it's because something was incorrectly *not* splitting and adding/moving the " characters fixed the split boundaries, but when testing afterward it appears that it's just mangled. I considered adding an informational if pycompat.iswindows and \ in the string about this issue, but was worried that might have too many false positives and did not do so at this time.

merge with stable

hgweb: show dates recorded in obsolescence markers Dates of operations that obsolete commits are also important enough to be shown, but maybe not as important as original commit dates, that and also for brevity is why they are wrapped in a <span> with only "age" class. Provided that JS is enabled, such elements only show age (e.g. "3 months ago"), and the exact date is visible in a tooltip. Commits dates, on the other hand, show both date and age (the latter in parenthesis). Example result for f1a0933ce59e from hg-committed: obsolete: pruned by Yuya Nishihara <yuya@tcha.org> 13 days ago

gitweb: make span.age CSS selector more specific This set of CSS properties is only used on /changelog page to make age elements float to the left and be fixed in size, but span.a is too broad of a selector, because we don't want to apply these properties to all <span> elements that have age class.

wireprotoserver: return to using iscmd() method This was teased out in part so remotefilelog could disable an old protocol method over http.

httppeer: remove redundant code to fetch capabilities _fetchcaps() is called by httppeer.instance(), which is the only instantiator of httppeer. Since _fetchcaps() always sets self._caps and since 197d10e157ce removed the fallback for cases where the remote doesn't support capabilities, we can remove some dead code from httppeer.capabilities().

tests: test using both versions of SSH protocol Now that the version 2 of the SSH protocol is usable in core, we can start actively testing it more widely outside of low-level protocol tests. We add #testcases variants to a handful of tests so we exercise both version 1 and version 2 of the SSH protocol when testing. This will allow us to more easily find regressions and variances as protocol 2 is developed. It will also make it easier to continue testing with protocol version 1 once version 2 is enabled by default. There are a handful of tests using ssh:// that should also gain test variances. One - test-push-race.t - already has a #testcases. This would require combinatorial cases. I didn't want to go down that rabbit hole, so that test is unchanged. Thinking aloud, there is probably an opportunity to automatically run tests with multiple server/protocol implementations. Ideally any test that performed server interaction would run with all supported server implementations and protocols so we could find variances between servers and protocols. But this has been a long-standing issue with our test harness. I don't think it is an easily solved problem. But it would be nice... Differential Revision: https://phab.mercurial-scm.org/D2206

sshpeer: log remote capabilities after protocol upgrade This helps reduce variance with version 1 and will help prevent test output divergence as we start testing protocol version 2 more widely. Differential Revision: https://phab.mercurial-scm.org/D2205

wireprotoserver: handle SSH protocol version 2 upgrade requests This commit teaches the SSH server to recognize the "upgrade" request line that clients send when they wish to switch the channel to version 2 of the SSH protocol. Servers don't honor upgrade requests unless an experimental config option is set. Since the built-in server now supports upgrade requests, our test server to test the handshake has been deleted. Existing tests use the built-in server and their output doesn't change. The upgrade is handled in our state machine. The end result is a bit wonky, as the server transitions back to version 1 state immediately after upgrading. But this will change as soon as version 2 has an actual protocol that differs from version 1. Tests demonstrating that the new server is a bit more strict about the upgrade handshake have been added. Differential Revision: https://phab.mercurial-scm.org/D2204

wireprotoserver: move SSH server operation to a standalone function The server-side processing logic will soon get a bit more complicated in order to handle protocol switches. We will use a state machine to help make the transitions clearer. To prepare for this, we move SSH server operation into a standalone function. We structure it as a very simple state machine. It only has two states for now, with one state containing the bulk of the logic. But things will evolve shortly. Differential Revision: https://phab.mercurial-scm.org/D2203

manifest: add support for including directories outside narrowspec When using tree manifests and the client doesn't have a directory, we have two choices for what to do with "hg manifest" output: 1) ignore the directory, and 2) include the directory (not files within it). For "hg files", we decided to ignore the directories (and files) outside the narrowspec. If we choose to not include directories outside the narrowspec, then I think we should also make sure we don't include files outside the narrowspec. I also think we should add --outside-narrow flag (or other name). Thus, whichever way we go, I think we should have a way of displaying paths (files or directories) outside the narrowspec. For that we'll need to handle the 't' flag that narrowhg uses, and that's what this patch adds support for. Differential Revision: https://phab.mercurial-scm.org/D2235

narrow: restrict manifest iteration by using manifest.walk(matcher) This is only for root nodes, so it shouldn't really matter (they're rarely huge), but seems cleaner. Differential Revision: https://phab.mercurial-scm.org/D2234

narrow: only diff manifest part within narrowspec when generating changegroup Since 959ebff3505a (manifest: add match argument to diff and filesnotin, 2017-03-07), we have a more efficient way of diffing manifests while applying a matcher. Let's use that while generating narrowed changegroups, so we avoid diffing parts of the manifest that don't match the narrowspec. Differential Revision: https://phab.mercurial-scm.org/D2233

progress: use '%*d' to pad progress value Follows up 7f5108e58083. The problem of '% Nd' is that ' ' means we want {' ' or '-'} as a sign character. We should instead write '%Nd' to pad up to N characters with space, and N can be '*'.

py3: stringify IOError/OSError without loosing local character Follows up fa4d333cac58. An environment error may contain non-ascii characters on Windows, which should be encoded to a platform-native string.

dirstate: drop explicit files that shouldn't match (BC) (issue4679) Before, wctx.walk() could include files excluded by -X pattern, which disagrees with wctx.matches() and ctx.walk()/matches() behavior. This patch fixes the problem by testing stat results against the matcher if the matcher may contain false paths. I have no idea if the fix should be made before the workaround for case- insensitive filesystems, but that shouldn't matter since match.anypats() means 'not match.isexact()'. This patch also makes narrow and sparse extensions to not exclude explicit paths on walk() because they appear to depend on the buggy behavior. More detailed analysis about this issue by Martin von Zweigbergk: "I think it's just an unintended consequence of how the dirstate walk works, but I'm not sure. The exception for explicit files also bothered me when I was working on the matcher code a year or so ago. I actually added the exception to the matcher code because I thought it was always working like that (not just for dirstate) in a83a7d27911e (match: handle excludes using new differencematcher, 2017-05-16). It was only recently that Yuya realized that it used to be inconsistent and that I probably made it consistently bad because I didn't realize it was inconsistent to start with, see 821d8a5ab4ff (match: do not weirdly include explicit files excluded by -X option, 2018-01-16)." .. bc:: Working-directory commands now respect ``-X PATTERN`` no matter if PATTERN matches explicitly-specified FILEs. For example, ``hg add foo -X foo`` no longer add the file ``foo``.

hgweb: show users recorded in obsolescence markers It's useful to see who obsoleted a commit, because it's not always done by its author (hg-committed is a good example, because people rebase stacks of commits made by various people). Usernames are obfuscated, but look correct (e.g. "&#116;&#101;&#115;&#116;" is "test").

revert: use an exact matcher in interactive diff selection (issue5789) When going through _performrevert() in the interactive case, we build a matcher with files to revert and pass it patch.diff() for later selection of diff hunks to revert. The files set used to build the matcher comes from dirstate and accounts for patterns explicitly passed to revert ('hg revert -i <file>') and, in case of nonexistent pattern, this set is empty (which is expected). Unfortunately, the matcher built from scmutil.match(ctx, []) is wrong as it leads patch.diff() to rebuild a 'changes' tuple with dirstate information, ignoring user-specified pattern. This leads to the situation described in issue5789, where one gets prompted about reverting files unrelated to specified patterns because they made a typo or so. We fix this by building an exact matcher with the correct set of file paths (built earlier). Thanks to Yuya Nishihara for suggesting the correct fix.

tests: add a test demonstrate that 'revert -i' ignores nonexistent patterns As described in issue5789, when revert is called through: hg revert -i <some file that does not exist> we'd expect the command to abort early. Currently, it just warns about missing file but prompt about files unrelated to user arguments.
