update: print warning about hidden changeset after update When an attempt to update to a hidden changeset fails because the working copy is dirty, you may get a message like this: updating to a hidden changeset 343f6de32686 (hidden revision '343f6de32686' was rewritten as: 4ab941244072) abort: conflicting changes (commit or update --clean to discard changes) It's easy to miss the real error here. This patch moves the warning about the hidden changeset to after the update has happened. It changes the verb tense accordingly (and drops the "a" that I think it sounds better without). Of course, this means that the commit isn't actually hidden anymore when the message is printed. I think that's fine. Differential Revision: https://phab.mercurial-scm.org/D3479

cborutil: port to Python 3 The only problem lurking in here was sorts of mismatched types. The sorts are only for output stability in our tests (sigh), so we just build a phony sort key using the __name__ of types so that we only compare like types against each other.

directaccess: use resolvehexnodeidprefix() instead of _partialmatch() Same reasoning as previous commit: I want to make resolvehexnodeidprefix() move complex and don't want to duplicate that code in directaccess. Differential Revision: https://phab.mercurial-scm.org/D3463

revset: use resolvehexnodeidprefix() in id() predicate (BC) We now have a public method for this purpose, so we don't need to access the private revlog._partialmatch(). Also, I'll probably make some changes to resolvehexnodeidprefix() later, and I want those to be reflected by the id() predicate. Note that this breaks a test case, because we now resolve the prefix in the unfiltered repo and get an ambiguous lookup, which results in no revision being added to the revset. The test case was already documented to be broken even though it wasn't. It's important to note that {shortest(node)} already uses the unfiltered repo, so we're not going to break people who get the prefix from there. I think we may not want to ever use shortest() in the filtered repo. It seems unlikely to be enough of a win to matter much. For example, in my hg repo, it would save me only 0.2 hex digits. In another repo that only I modify, it saves a little more, but it's still only 0.29 hex digits. It seems unlikely that people will prune enough commits that only 1/16 of the commits are visible (which is what it would take a to save a single hex digit). Instead, I'm working on another approach: allow ambiguous matches to be disambiguated within a user-specified revset. Whether or not that pans out, I hope we're okay with this little change in behavior for now and we can decide what to do about it later. Differential Revision: https://phab.mercurial-scm.org/D3311

revset: make id() an empty set for ambiguous nodeid (BC) As Yuya pointed out in the review of D3311, id() (and rev()) does not raise an error when the input is an unknown identifier, so it doesn't make sense for it to do that when the input is ambiguous with a filtered node. However, it turned out that it already does raise an error when the input is ambiguous among the visible nodes. So let's start by fixing that. Differential Revision: https://phab.mercurial-scm.org/D3462

shortest: don't keep checking for longer prefix if node doesn't exist (API) If revlog.shortest() is called with an invalid nodeid, we keep checking if longer and longer prefixes are valid. We call revlog._partialmatch() for each prefix. That function will give us None if the node doesn't exist (and a RevlogError if it's ambiguous), so there's no need to keep checking. This patch instead makes revlog.shortest() raise a LookupError is the node does not exist, and updates the caller to handle it. Before this patch, revlog.shortest() would return the full hexnode for nonexistent nodeids. By the same reasoning as in 7b2955624777 (scmutil: make shortesthexnodeidprefix() take a full binary nodeid, 2018-04-14), it's not revlog.shortest() that should decide how to present nonexistent nodeids, so that's now moved to the template function. This should speed up cases where {shortest()} is applied to an invalid nodeid, but I couldn't think of a reasonable case where that would happen. Differential Revision: https://phab.mercurial-scm.org/D3461

shortest: extract function for checking if a prefix is a revnum Much of isvalid() was about testing if a prefix is a valid revnum. I want to reuse that soon, so let's move it out. There is no significant slowdown from the function call overhead. Differential Revision: https://phab.mercurial-scm.org/D3460

shortest: rename "test" variable to "prefix" Sorry if this is considered churn, but "prefix" just seems much clearer to me. Differential Revision: https://phab.mercurial-scm.org/D3459

shortest: move some safe code out of exception block The RevlogError and WdirUnsupported could be raised by _partialmatch(), but not by the rest of isvalid(), so let's move the rest out to make it clearer. Differential Revision: https://phab.mercurial-scm.org/D3458

revlog: don't say "not found" on internal error If index_node() returned NULL, then index_find_node() and and nt_partialmatch() used to return -2 to signal that the node was not found. However, we were passing in a revnum to index_node() that we knew should exist, so the only reason it could return NULL was due to some internal error or perhaps out of memory. Let's not use "not found" for these cases. I suppose we never noticed this because these error never happen in practice. I think there are more places where we should error out instead of reporting that the node was not found, but the cases mentioned above were all I cared about right now (because using the same error code for all failures simplified some future patches). Differential Revision: https://phab.mercurial-scm.org/D3457

revlog: extract function for getting node from known-to-exist rev Many of the calls to index_node() (which converts a rev to a nodeid) are done with a rev that's know to exist. If the function fails, there's something really wrong and we should just abort. This was done in only one place. This patch starts by extracting that code to a function that we can reuse in later patches. Differential Revision: https://phab.mercurial-scm.org/D3456

shortest: make {shortest("fffffffff")} work again {shortest("fffffffff")} should shorten it to the shortest unambiguous prefix for the working directory. It used to do that until I broke it in 7b2955624777 (scmutil: make shortesthexnodeidprefix() take a full binary nodeid, 2018-04-14), when we started returning the full hex nodeid for any working directory prefix shorter than 40 hex digits. This patch fixes it by catching WdirUnsupported specifically. Differential Revision: https://phab.mercurial-scm.org/D3455

revlog: use radix tree also for matching keys shorter than 4 hex digits I don't know what the reason for the 4-digit limit was, and I can't think of any real disadvantages of using the radix tree also when the requested minimum length is short. This speeds up `hg log -T '{shortest(node,1)}\n'` from 2m16s to 4.5s by making that not fall back to pure code. Differential Revision: https://phab.mercurial-scm.org/D3453

context: convert to hex for error message only for 20-byte changeid Now that 20-byte strings unambiguously mean binary (or a bug), we can specialize the conversion to hex for that case. Differential Revision: https://phab.mercurial-scm.org/D3452

context: clarify that only one attempt is made to interpret changeid We can now tell what type of revision specifier we have just by looking at it (we no longer attempt to interpret it in one way after the other -- that's now in scmutil.revsymbol()). Let's clarify this in the code by swithing to if/elif. Differential Revision: https://phab.mercurial-scm.org/D3451

context: only bother looking for broken dirstate for 20-byte changeid If we fail to look up a changeid in changectx.__init__, we check if it exactly matches any of the dirstate parents, and if it does, we print a more specific message ("working directory has unknown parent '...'!" instead of "unknown revision '...'"). The dirstate parents are always 20 bytes, so there's no need to check for a match when the given changeid is not 20 bytes. (And now that all the other allowed forms of changeid have been moved out of the constructor, there's no risk that a changeid that did match a dirstate parent was actually a valid bookmark.) Differential Revision: https://phab.mercurial-scm.org/D3450

revset: pass in lookup function to matchany() (issue5879) Silly mistake in f83cb91b052e.

test-hgweb: add test for foo-bar name lookup This is broken since f83cb91b052e "revset: pass in lookup function instead of repo (API)."

context: drop support for looking up context by ambiguous changeid (API) This removes support for using the changectx constructor (and thereby repo[x]) for looking up contexts by a stringified int, a namespace key (e.g. a bookmark), or a partial hex nodeid. This means that e.g. repo[<hex nodeid>] will now fail even if a bookmark with the same name exists (which is a good thing IMO). It also means that doing repo[<non-existent node>] no longer ends up loading namespaces (which was a surprising side-effect of creating of failing to create a context object that I recently ran into while debugging something unrelated to this series). Differential Revision: https://phab.mercurial-scm.org/D3449

tests: pass parent revision as integer to repo[x] in test-context-metadata.t Support for looking up by stringified int is going away. It's already deprecated, but I think I didn't notice this case because the test case pipes through `grep`. Differential Revision: https://phab.mercurial-scm.org/D3448

bookmarks: cache reverse mapping (issue5868) I chose a simpler implementation. If the initial cost of building reverse mapping is significant, we'll have to move it under @propertycache. The nodemap could be a dict of sets, but I think keeping a sorted list is better since each node is likely to have zero/one bookmark. Micro-benchmark with 1001 bookmarks and 1001 revisions: $ for n in `seq 0 1000`; do touch $n; hg book book$n; hg ci -qAm$n; done $ hg bookmarks --time > /dev/null (orig) time: real 0.040 secs (user 0.050+0.000 sys 0.000+0.000) (new) time: real 0.040 secs (user 0.040+0.000 sys 0.010+0.000) $ hg log -T '{bookmarks}\n' --time > /dev/null (orig) time: real 0.160 secs (user 0.160+0.000 sys 0.000+0.000) (new) time: real 0.090 secs (user 0.100+0.000 sys 0.000+0.000)

tests: remove pid file by default Previously, killdaemons.py would kill PIDs listed in a file then leave the file lingering around. If the PIDs are killed, then there's no point leaving the PID file around. In the worst case, a later invocation of killdaemons.py (run-tests.py invokes killdaemons.py after running a test) could kill a separate process whose PID conflicted with a previously-killed process. By removing the PID file, we eliminate this possibility. Some tests were manually removing the PID file after calling killdaemons.py. So we update these tests to not do this. Differential Revision: https://phab.mercurial-scm.org/D3443

tests: remove #require killdaemons The killdaemons hghave feature has returned True since it was introduced in 448d0c452140. As such, "#require killdaemons" has no effect and is superfluous. So we remove instances of it. Differential Revision: https://phab.mercurial-scm.org/D3442

pycompat: export queue module instead of symbols in module (API) Previously, pycompat and util re-exported individual symbols from the queue module. This had the side-effect of forcing the loading of the queue module whenever pycompat/util was imported. These symbols aren't used very often. So importing the module to get a handle on the symbols is wasteful. This commit changes pycompat so it no longer exports the individual symbols in the queue module. Instead, we make the imported module a "public" symbol. We drop the individual symbol aliases from the util module. All consumers are updated to use pycompat.queue.* instead. This change makes 300 invocations of `hg log -r. -T '{rev}\n'` a little faster: before: 18.44s after: 17.87s Differential Revision: https://phab.mercurial-scm.org/D3441

demandimport: make module ignores a set (API) The list of modules to ignore is used for membership testing. Yet it is defined as a list. Sets are more efficient for membership testing. So this commit converts the module list to a set. Since we took an API hit, I renamed the variable to further clarify the change.

filelog: don't crash on invalid copy metadata (issue5748) "copy" and "copyrev" are both supposed to appear next to each other. However, a user report demonstrated a crash that indicates that something in the wild is producing "copy" without "copyrev" (probably `hg convert`). While we should definitely fix the source of the bad metadata, the bad code causing the crash is already in the wild and who knows how many repositories are impacted. So let's be more defensive when accessing the file revision metadata.

httppeer: detect redirect to URL without query string (issue5860) 197d10e157ce subtly changed the HTTP peer's handling of HTTP redirects. Before that changeset, we instantiated an HTTP peer instance and performed the capabilities lookup with that instance. The old code had the following relevant properties: 1) The HTTP request layer would automatically follow HTTP redirects. 2) An encountered HTTP redirect would update a peer instance variable pointing to the repo URL. 3) The peer would automagically perform a "capabilities" command request if a caller requested capabilities but capabilities were not yet defined. The first HTTP request issued by a peer is for ?cmd=capabilities. If the server responds with an HTTP redirect to a ?cmd=capabilities URL, the HTTP request layer automatically followed it, retrieved a valid capabilities response, and the peer's base URL was updated automatically so subsequent requests used the proper URL. In other words, things "just worked." In the case where the server redirected to a URL without the ?cmd=capabilities query string, the HTTP request layer would follow the redirect and likely encounter HTML. The peer's base URL would be updated and the unexpected Content-Type would raise a RepoError. We would catch RepoError and immediately call between() (testing the case for pre 0.9.1 servers not supporting the "capabilities" command). e.g. try: inst._fetchcaps() except error.RepoError: inst.between([(nullid, nullid)]) between() would eventually call into _callstream(). And _callstream() made a call to self.capable('httpheader'). capable() would call self.capabilities(), which would see that no capabilities were set (because HTML was returned for that request) and call the "capabilities" command to fetch capabilities. Because the base URL had been updated from the redirect, this 2nd "capabilities" command would succeed and the client would immediately call "between," which would also succeed. The legacy handshake succeeded. Only because "capabilities" was successfully executed as a side effect did the peer recognize that it was talking to a modern server. In other words, this all appeared to work accidentally. After 197d10e157ce, we stopped calling the "capabilities" command on the peer instance. Instead, we made the request via a low-level opener, detected the redirect as part of response handling code, and passed the redirected URL into the constructed peer instance. For cases where the redirected URL included the query string, this "just worked." But for cases where the redirected URL stripped the query string, we threw RepoError and because we removed the "between" handshake fallback, we fell through to the "is a static HTTP repo" check and performed an HTTP request for .hg/requires. While 197d10e157ce was marked as backwards incompatible, the only intended backwards incompatible behavior was not performing the "between" fallback. It was not realized that the "between" command had the side-effect of recovering from an errant redirect that dropped the query string. This commit restores the previous behavior and allows clients to handle a redirect that drops the query string. In the case where the request is redirected and the query string is dropped, we raise a special case of RepoError. We then catch this special exception in the handshake code and perform another "capabilities" request against the redirected URL. If that works, all is well. Otherwise, we fall back to the "is a static HTTP repo" check. The new code is arguably better than before 197d10e157ce, as it is explicit about the expected behavior and we avoid performing a "between" request, saving a server round trip.

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.

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.

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.

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.

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.
