paper: add href="#" to links with click handlers This restores the styling that was accidentally removed by the previous change to these files. Differential Revision: https://phab.mercurial-scm.org/D3438

paper: don't register click handlers with inline javascript (issue5812) The use of inline href="javascript:" undermines CSP policies that don't allow inline javascript. This commit changes the registering of the diffstat and line wrapping toggle handlers to the the global DOMContentLoaded handler, thus eliminating all inline javascript from the paper template.

hgweb: allow Content-Security-Policy header on 304 responses (issue5844) A side-effect of 98baf8dea553 was that the Content-Security-Policy header was set on all HTTP responses by default. This header wasn't in our list of allowed headers for HTTP 304 responses. This would trigger a ProgrammingError when a 304 response was issued via hgwebdir. This commit adds Content-Security-Policy to the allow list of headers for 304 responses so we no longer encounter the error. Differential Revision: https://phab.mercurial-scm.org/D3436

hgweb: discard Content-Type header for 304 responses (issue5844) A side-effect of 98baf8dea553 was that hgwebdir always sets a global default for the Content-Type header. HTTP 304 responses don't allow the Content-Type header. So a side-effect of this change was that HTTP 304 responses served via hgwebdir resulted in a ProgrammingError being raised. This commit teaches our 304 response issuing code to drop the Content-Type header. Differential Revision: https://phab.mercurial-scm.org/D3435

tests: add tests demonstrating ISE for HTTP 304 responses with hgwebdir There are two separate failures here. One for the Content-Type header. Another for the Content-Security-Policy header. Differential Revision: https://phab.mercurial-scm.org/D3434

test-push-http: do not clear pid file It's okay now, but we'll end up leaking daemon processes if we add some more.

debugcolor: fix crash by empty styles (issue5856)

tests: explicitly define compression engines for tests The zstd compression engine requires C extensions and isn't present in pure Python builds. The compression engine list leaks into the server capabilities string. Unless we're testing functionality specific to a compression format, the set of compression formats supported by a server doesn't matter much. So this commit explicitly defines the server's compression engines for some tests so behavior is consistent between pure and non-pure builds.

tests: update no-zstd branch of test-treediscovery.t as in 330ada7e8ea5 This side of the test got overlooked. We should probably consider having a way to run some of our tests through a "no-zstd" case just like we run some things through a "no-obsmarkers" case, but that's not an appropriate thing for stable. Differential Revision: https://phab.mercurial-scm.org/D3430

tests: glob away content-length changes relating to missing zstd bindings This doesn't fix everything in these two tests around missing zstd: we still get some changes in the CBOR payload in ways that I think we probably shouldn't bother to glob around. Maybe we should just disable zstd support in some of these lower-level wireproto tests? Differential Revision: https://phab.mercurial-scm.org/D3429

revlog: make pure version of _partialmatch() support 40-byte hex nodeids Without this patch, test-histedit-arguments.t would fail when run with --pure. It turned out to be because the pure version of _partialmatch() does not support full 40-byte hex nodeids. When histedit's instructions include things like "pick tip", it resolves the "tip" revision early to a full nodeid (but plain hex nodeid prefixes are not resolved to full nodeids). Then the nodeid (full or not) is looked up using to a full nodeid later. This step is what fails in pure mode. It has been failing since my c4131138eadb (histedit: look up partial nodeid as partial nodeid, 2018-04-06). I haven't verified, but I suspect histedit instructions like "pick <full hex nodeid>" would have been failing before my commit too, though. The fix is trivial: change a "< 40" to "<= 40".

hgweb: reuse body file object when hgwebdir calls hgweb (issue5851) An unintended side-effect of f0a851542a05 was that the request body file object (which uses a util.cappedreader) was constructed twice when hgwebdir called into hgweb. Since we attempt to read all remaining data from this file object when Content-Length is defined and since there were two instances of this object and the client supplied no additional data to read, this resulted in deadlock. The fix implemented in this commit is to reuse the request body file object when it is passed from hgwebdir to hgweb. A test demonstrating `hg clone` and `hg push` via hgwebdir has been added. Without this patch, the test hangs when doing `hg clone`. Surprisingly, this must mean that we have effectively no test coverage of the wire protocol when run via hgwebdir.

remotenames: mark the extension as EXPERIMENTAL I still don't feel confident about locking the behavior of all the things in the remotenames extension. Moreover the extension was introduced in this cycle only. Let's mark this extension EXPERIMENTAL for now so that we can change things especially the storage layer if required in next cycle. I will like to use cbor at storage layer too. Differential Revision: https://phab.mercurial-scm.org/D3426

sshpeer: reflect actual command activity one handshake The output from devel-peer-request is expected to give data about request and roundtrip done to the server. Changeset a9cffd14aa04 changed some of that by grouping hello and between commands call. However, the old sequence of command was "emulated" in sshpeer. Update the sshpeer to reflect this grouping of commands and update the tests that use it.

tests: drop a useless glob in test-infinite-bundlestore.t With the previous breakage tamed, the lack of test output difference was causing the test runner to report "no result code from test" because of this glob.

infinitepush: ensure fileindex bookmarks use '/' separators (issue5840) After loading up with status messages, I noticed that the subsequent matcher was rejecting 'scratch\mybranch' on Windows. No bookmarks were reported back, and the tests subsequently failed. I did a search for 'match', and nothing else looks like it needs to be fixed up, but someone who understands this code should also take a look. I also tried setting `infinitepush.branchpattern=re:scratch\\.*` in library-infinitepush.sh without this change, but that didn't work. Still, should we ban '\' in these bookmarks to avoid confusion? I thought I saw code that sandwiches a pattern between 're:^' and '.*', so perhaps regex characters will need special care? I also noticed comments in externalbundlestore.{read,write} that it won't work on Windows because of opening an open file. But I don't see a test failure, so this may lack test coverage.

interfaceutil: module to stub out zope.interface The startup time of `hg` increased during the 4.6 development cycle. A cause of that was importing more modules and doing more work at module import time. The import of zope.interface and the declaring of various interfaces is partially responsible for the startup time regression. Our current usage of zope.interface doesn't do much at run time: we are merely declaring interfaces and stating that certain types implement various interfaces. Core Mercurial is not (yet) using of any of zope.interface features that actually require that interface plumbing be defined. The only place we actually need the interface metadata is in test-check-interfaces.py. This commit establishes a new interfaceutil module. It exposes the subset of the zope.interface API that we currently use. By default, the APIs no-op. But if an environment variable is set, we export the real zope.interface APIs. Existing importers of zope.interface have been converted to use the new module. test-check-interfaces.py has been updated to define the environment variable so the real zope.interface is used. The net effect of this change is we stop importing 9 zope.interface.* modules and we no longer perform interface bookkeeping when registering interfaces. On my i7-6700K on Linux, a shell loop that runs `hg log -r .` 300 times on a repo with 1 commit shows a significant CPU time improvement (average of 4 runs): 4.5: 14.814s before: 19.028s after: 16.945s And with `run-tests.py -j10` (single run): 4.5: ~3100s (~51.7m) before: ~4450s (~74.2m) after: ~3980s (~66.3m) So this claws back about half of the regressions in 4.6.
