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.

date: fix parsing months Thanks nemo for discovering this on #mercurial IRC channel. Test Plan: Add a test. It fails before this patch: ``` + hg: parse error: invalid date: 'Feb 2018' + hg: parse error: invalid date: 'Apr 2018' + hg: parse error: invalid date: 'Jun 2018' + hg: parse error: invalid date: 'Sep 2018' + hg: parse error: invalid date: 'Nov 2018' ``` Differential Revision: https://phab.mercurial-scm.org/D2289

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. It got dropped accidentally in the recent refactor, but the code was all still present so it's easy to support for now. I think once we land remotefilelog, we should probably inline this function.

httppeer: remove httpspeer All it did was verify at construction time that Mercurial supports TLS. instance() is what's used to construct peer instances. So we can just inline this check into that function and do away with the type variant. Differential Revision: https://phab.mercurial-scm.org/D2216

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(). Differential Revision: https://phab.mercurial-scm.org/D2215

httppeer: change logic around argument handling The code to process arguments only makes sense if there are arguments. So change an "else" to "elif args", remove an "if" that isn't necessary, and add some docs for good measure. Differential Revision: https://phab.mercurial-scm.org/D2214

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.

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
