tests: fix error case in test-url.py's doctest This required some careful attention, so I wanted to split it out from the uninteresting bits that'll be in the next change. Differential Revision: https://phab.mercurial-scm.org/D3469

sslutil: fix some edge cases in Python 3 support Detected by fixing up test-url.py on Python 3. Differential Revision: https://phab.mercurial-scm.org/D3467

tests: port test-hybridencode.py to unittest This was done predominantly through keyboard macros in emacs, so it's not always pretty, but it's enough to make the test easier to work with. There's a ton of room for improvement in this file, but it would be labor intensive and error-prone, so I went with the dumbest option that could work, so as to avoid transcription errors. Paranoia: $ egrep '^ def test' tests/test-hybridencode.py | wc -l 44 $ egrep '^ def test' tests/test-hybridencode.py | sort | uniq | wc -l so I'm pretty confident there aren't any shadowed test methods. This fixes the test on Python 3. Differential Revision: https://phab.mercurial-scm.org/D3466

tests: make test-check-interfaces.py work on Python 3 # skip-blame just a bunch of bytes prefixes Differential Revision: https://phab.mercurial-scm.org/D3465

scmutil: clean up bytes/string cache decorator mess on Python 3 again The previous fix to this area worked, but was dropping bytes in __dict__ on Python 3. This was causing subtle breakage in test-check-interfaces.py, and probably other things too. Fixed now. Differential Revision: https://phab.mercurial-scm.org/D3464

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

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)

bookmarks: make argument names of _set/_del() more specific

bookmarks: extract function that looks up bookmark names by node

bookmarks: hide dict behind bmstore class This should make it clearer that the bmstore doesn't expose all dict APIs.

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. This appears to reduce the CPU time for running 300 invocations of `hg log -r. -T '{rev}'` on my i7-6700K: before: 18.64s after: 18.44s Differential Revision: https://phab.mercurial-scm.org/D3440

cmdutil: remove unused 'confirmopts' constant Follows up f10cb49951e1.

formatter: ditch namedtuple in favor of attr

log: consume --stat/patch options at constructor of changesetprinter The variable name, self.diffopts, was confusing. Let's split it to two booleans.

log: cache diffopts instance It appears that calling patch.diff*opts() repeatedly has some cost. $ hg log -T '{rev}\n' -R mercurial --time > /dev/null (orig) time: real 4.430 secs (user 4.370+0.000 sys 0.050+0.000) (new) time: real 1.950 secs (user 1.880+0.000 sys 0.060+0.000) 'diffopts or {}' isn't necessary as patch.diff*opts() accepts opts=None.

encoding: alias cp65001 to utf-8 on Windows As far as I can tell, cp65001 is the Windows name for UTF-8. I don't know how different it is from the UTF-8, but Python 3 appears to have introduced new codec for cp65001, so the alias is enabled only for Python 2. https://bugs.python.org/issue13216 This patch is untested, but hopefully fixes the following issue. https://bitbucket.org/tortoisehg/thg/issues/5127/

windows: fix incorrect detection of broken pipe when writing to pager Paging e.g. hg incoming on Windows and quitting the pager before the output is consumed will print 'abort: Invalid argument'. This is because the windows error 0xE8 (ERROR_NO_DATA) is mapped to EINVAL even though it is documented as 'The pipe is being closed'. Note that this fix assumes that Windows' last error code is still valid in the exception handler. It works correctly in all my tests. A simpler fix would be to just map EINVAL to EPIPE, like was done is flush previously, but that would be less precise. This error was not observed previously, when pager was an extension.
