Merge upstream Ruby (#25)
* Evaluate multiple assignment left hand side before right hand side In regular assignment, Ruby evaluates the left hand side before the right hand side. For example: ```ruby foo[0] = bar ``` Calls `foo`, then `bar`, then `[]=` on the result of `foo`. Previously, multiple assignment didn't work this way. If you did: ```ruby abc.def, foo[0] = bar, baz ``` Ruby would previously call `bar`, then `baz`, then `abc`, then `def=` on the result of `abc`, then `foo`, then `[]=` on the result of `foo`. This change makes multiple assignment similar to single assignment, changing the evaluation order of the above multiple assignment code to calling `abc`, then `foo`, then `bar`, then `baz`, then `def=` on the result of `abc`, then `[]=` on the result of `foo`. Implementing this is challenging with the stack-based virtual machine. We need to keep track of all of the left hand side attribute setter receivers and setter arguments, and then keep track of the stack level while handling the assignment processing, so we can issue the appropriate topn instructions to get the receiver. Here's an example of how the multiple assignment is executed, showing the stack and instructions: ``` self # putself abc # send abc, self # putself abc, foo # send abc, foo, 0 # putobject 0 abc, foo, 0, [bar, baz] # evaluate RHS abc, foo, 0, [bar, baz], baz, bar # expandarray abc, foo, 0, [bar, baz], baz, bar, abc # topn 5 abc, foo, 0, [bar, baz], baz, abc, bar # swap abc, foo, 0, [bar, baz], baz, def= # send abc, foo, 0, [bar, baz], baz # pop abc, foo, 0, [bar, baz], baz, foo # topn 3 abc, foo, 0, [bar, baz], baz, foo, 0 # topn 3 abc, foo, 0, [bar, baz], baz, foo, 0, baz # topn 2 abc, foo, 0, [bar, baz], baz, []= # send abc, foo, 0, [bar, baz], baz # pop abc, foo, 0, [bar, baz] # pop [bar, baz], foo, 0, [bar, baz] # setn 3 [bar, baz], foo, 0 # pop [bar, baz], foo # pop [bar, baz] # pop ``` As multiple assignment must deal with splats, post args, and any level of nesting, it gets quite a bit more complex than this in non-trivial cases. To handle this, struct masgn_state is added to keep track of the overall state of the mass assignment, which stores a linked list of struct masgn_attrasgn, one for each assigned attribute. This adds a new optimization that replaces a topn 1/pop instruction combination with a single swap instruction for multiple assignment to non-aref attributes. This new approach isn't compatible with one of the optimizations previously used, in the case where the multiple assignment return value was not needed, there was no lhs splat, and one of the left hand side used an attribute setter. This removes that optimization. Removing the optimization allowed for removing the POP_ELEMENT and adjust_stack functions. This adds a benchmark to measure how much slower multiple assignment is with the correct evaluation order. This benchmark shows: * 4-9% decrease for attribute sets * 14-23% decrease for array member sets * Basically same speed for local variable sets Importantly, it shows no significant difference between the popped (where return value of the multiple assignment is not needed) and !popped (where return value of the multiple assignment is needed) cases for attribute and array member sets. This indicates the previous optimization, which was dropped in the evaluation order fix and only affected the popped case, is not important to performance. Fixes [Bug ruby#4443] * * 2021-04-22 [ci skip] * Remove reverse VM instruction This was previously only used by the multiple assignment code, but is no longer needed after the multiple assignment execution order fix. * fix raise in exception with jump add_ensure_iseq() adds ensure block to the end of jump such as next/redo/return. However, if the rescue cause are in the body, this rescue catches the exception in ensure clause. iter do next rescue R ensure raise end In this case, R should not be executed, but executed without this patch. Fixes [Bug #13930] Fixes [Bug #16618] A part of tests are written by @jeremyevans ruby#4291 * [ruby/time] Make Time friendly to Ractor ruby/time@c784e4f166 * [ruby/cgi] handle invalid encoding ruby/cgi@2b1c2e21a4 * [ruby/cgi] Add test for escapeHTML/unescapeHTML invalid encoding fix in pure ruby version Also, remove pointless assert_nothing_raised(ArgumentError) while here. ruby/cgi@c05edf5608 * [ruby/cgi] gemspec: Explicitly empty executables list The gem exposes no executables ruby/cgi@cd7106ad97 * [ruby/benchmark] Add comment about terminating newline in captions; fix test method name. ruby/benchmark@02ce298d3e * [ruby/benchmark] gemspec: Explicitly have 0 executables This gem exposes no executables. ruby/benchmark@ff1ef7ae06 * Ignore JRuby files on io-console * [ruby/io-console] Enable building the C extension on TruffleRuby. ruby/io-console@c17b8cf3a9 * [ruby/io-console] Move FFI console under lib Having the separate dir makes testing difficult and doesn't reflect the structure the gem will eventually have. We can filter these files out if necessary when building the CRuby gem. ruby/io-console@881010447c * Separate test used by test_ractor for Ractor in test_time.rb * Merge net-imap-0.2.0 * [ruby/net-imap] Set timeout for IDLE responses Fixes #14 ruby/net-imap@39d39ff9bb * [ruby/net-imap] Bump version to 0.2.1 ruby/net-imap@31f96ea884 * [ruby/uri] Upstream Java proxy property checks from JRuby These Java properties, retrieved from JRuby's "Java env" ENV_JAVA, allow JRuby users to use the same proxy properties the rest of the Java platform uses. This resolves https://bugs.ruby-lang.org/issues/11194 ruby/uri@3bd2bcc95a * [ruby/uri] Optimize URI#hostname and URI#hostname= ruby/uri@3b7ccfd835 * [ruby/uri] Add tests for URI::RFC{2396,3986}_Parser#inspect ruby/uri@d47dae2f8e * [ruby/uri] Only use UnboundMethod#bind_call if it is available This allows tests to pass on Ruby 2.4-2.6. Fixes #19 ruby/uri@67ca99ca87 * [ruby/uri] Set required_ruby_version to 2.4 in gemspec Tests pass on Ruby 2.4, but not on Ruby 2.3. ruby/uri@594418079a * [ruby/uri] remove comment about URI::escape as it is removed ruby/uri@0f0057e1b2 * [ruby/uri] Use Regexp#match? to avoid extra allocations `#=~` builds `MatchData`, requiring extra allocations as compared to `#match?`, which returns a boolean w/o having to build the `MatchData`. ruby/uri@158f58a9cc * Update bundled_gems * Suppress warnings for unsued variable * * 2021-04-23 [ci skip] * Remove unneeded comment * test/ruby/test_assignment.rb: Avoid "assigned but unused variable" * Fix wrong documentation It doesn't return `nil` but raises an exception, as explained a few lines after * * 2021-04-24 [ci skip] * Fix setting method visibility for a refinement without an origin class If a class has been refined but does not have an origin class, there is a single method entry marked with VM_METHOD_TYPE_REFINED, but it contains the original method entry. If the original method entry is present, we shouldn't skip the method when searching even when skipping refined methods. Fixes [Bug #17519] * Remove unnecessary checks for empty kw splat These two checks are surrounded by an if that ensures the call site is not a kw splat call site. * Remove part of comment that is no longer accurate In Ruby 2.7, empty keyword splats could be added back for backwards compatibility. However, that stopped in Ruby 3.0. * Add back checks for empty kw splat with tests (ruby#4405) This reverts commit a224ce8. Turns out the checks are needed to handle splatting an array with an empty ruby2 keywords hash. * [Doc] Fix a typo s/invokations/invocations/ * * 2021-04-25 [ci skip] * [Doc] Fix a typo s/evel/eval/ * [Doc] Fix a typo s/oher/other/ * [Doc] Fix a typo s/visilibity/visibility/ * [Doc] Fix a typo s/arround/around/ * [Doc] Fix a typo s/daguten/dakuten/ * [ci skip] Fix a typo s/certificiate/certificate/ * [Doc] Fix a typo s/algorthm/algorithm/ * Fix some typos by spell checker * * 2021-04-26 [ci skip] * Remove test of removed reverse VM instruction since 5512353 * spec/ruby/core/file/shared/read.rb: The behavior of FreeBSD was changed http://rubyci.s3.amazonaws.com/freebsd12/ruby-master/log/20210426T003001Z.fail.html.gz#rubyspec * disable shareable_constant_value for CI To debug CI failures on FreeBSD, disable `shareable_constant_value`. * [ruby/irb] Fix typo ture -> true [ci skip] ruby/irb@783a0569e8 * [ruby/irb] Added assert_equal_with_term ruby/irb@b690da96d8 * [ruby/irb] Added test_colorize ruby/irb@10e290fc3a * [ruby/irb] Assertions on non-tty ruby/irb@ede12890d2 * [ruby/irb] Added `colorable` keyword option Currently `IRB::Color.colorize` and `IRB::Color.colorize_code` refer `$stdin.tty?` internally. This patch adds `colorable` keyword option which overrides it. ruby/irb@402e3f1907 * [ruby/irb] Added setup and teardown to TestIRB::TestInit Not to be affected by existing rc files in all tests. ruby/irb@bf434892b4 * node.c (rb_ast_new): imemo_ast is WB-unprotected Previously imemo_ast was handled as WB-protected which caused a segfault of the following code: # shareable_constant_value: literal M0 = {} M1 = {} ... M100000 = {} My analysis is here: `shareable_constant_value: literal` creates many Hash instances during parsing, and add them to node_buffer of imemo_ast. However, the contents are missed because imemo_ast is incorrectly WB-protected. This changeset makes imemo_ast as WB-unprotected. * Revert "disable shareable_constant_value for CI" This reverts commit c647205. Maybe the root issue was fixed by 7ac078e * Document binding behavior for C call/return events for TracePoint/set_trace_func C methods do not have bindings, so binding returns the binding of the nearest C method. Fixes [Bug ruby#9009] * * 2021-04-27 [ci skip] * Fix compiler warnings in objspace_dump.c when assertions are turned on Example: ``` In file included from ../../../include/ruby/defines.h:72, from ../../../include/ruby/ruby.h:23, from ../../../gc.h:3, from ../../../ext/objspace/objspace_dump.c:15: ../../../ext/objspace/objspace_dump.c: In function ‘dump_append_ld’: ../../../ext/objspace/objspace_dump.c:95:26: warning: comparison of integer expressions of different signedness: ‘long unsigned int’ and ‘int’ [-Wsign-compare] 95 | RUBY_ASSERT(required <= width); | ^~ ``` * Fix type-o in insns.def "redefine" -> "redefined" * Partially revert 2c7d3b3 to make imemo_ast WB-protected again. Only the test is kept. * Make imemo_ast WB-protected again by firing the write barrier of imemo_ast after nd_lit is modified. This will fix the issue of ruby#4416 more gracefully. * test/ruby/test_exception.rb: suppress "warning: statement not reached" * [ruby/pathname] gemspec: Explicitly list 0 executables This gem exposes no executables. ruby/pathname@c401d97d58 * [ruby/gdbm] Add dependency to gdbm package on mingw RubyInstaller2 supports metadata tags for installation of dependent MSYS2/MINGW libraries. The openssl gem requires the mingw-openssl package to be installed on the system, which the gem installer takes care about, when this tag is set. The feature is documented here: https://github.com/oneclick/rubyinstaller2/wiki/For-gem-developers#msys2-library-dependency Fixes oneclick/rubyinstaller2#163 ruby/gdbm@d95eed3e86 * [ruby/matrix] Use Gemfile instead of Gem::Specification#add_development_dependency. ruby/matrix@1381fde5c1 * [ruby/matrix] v0.4.0 ruby/matrix@baea4b90d4 * [ruby/matrix] v0.4.1 ruby/matrix@f7c9981907 * [ruby/matrix] Guard for < Ruby 3.0 ruby/matrix@1ef660c627 * [ruby/net-ftp] Re-apply 827e471d438fdec1ae329afb5912b8e06d534823 ruby/net-ftp@3ca80368c4 * [ruby/net-ftp] Replace Timeout.timeout with socket timeout Timeout.timeout is inefficient since it spins up a new thread for each invocation, use Socket.tcp's connect_timeout option instead when we aren't using SOCKS (we can't replace Timeout.timeout for SOCKS yet since SOCKSSocket doesn't have a connect_timeout option). ruby/net-ftp@d65910132f * [ruby/net-ftp] Close the passive connection data socket if there is an error setting up the transfer Previously, the connection leaked in this case. This uses begin/ensure and checking for an error in the ensure block. An alternative approach would be to not even perform the connection until after the RETR (or other) command has been sent. However, I'm not sure all FTP servers support that. The current behavior is: * Send (PASV/EPSV) * Connect to the host/port returned in 227/229 reply * Send (RETR/other command) Changing it to connect after the RETR could break things. FTP servers might expect that the client has already connected before sending the RETR. The alternative approach is more likely to introduce backwards compatibility issues, compared to the begin/ensure approach taken here. Fixes Ruby Bug 17027 ruby/net-ftp@6e8535f076 * [ruby/net-ftp] Reduce resource cosumption of Net::FTP::TIME_PARSER Reported by Alexandr Savca as a DoS vulnerability, but Net::FTP is a client library and the impact of the issue is low, so I have decided to fix it as a normal issue. Based on patch by nobu. ruby/net-ftp@a93af636f8 * [ruby/net-ftp] Add test cases ruby/net-ftp@865232bb2a * [ruby/net-ftp] Replace "iff" with "if and only if" iff means if and only if, but readers without that knowledge might assume this to be a spelling mistake. To me, this seems like exclusionary language that is unnecessary. Simply using "if and only if" instead should suffice. ruby/net-ftp@e920473618 * lldb: Add Freelist Index to dump_page output * lldb: dump_page_rvalue - dump a heap page containing an RVALUE rather than having to do this in a two step process: 1. heap_page obj 2. dump_page $2 (or whatever lldb variable heap_page set) we can now just dump_page_rvalue obj * lldb: highlight the slot when using dump_page_rvalue * Fix Monitor to lock per Fiber, like Mutex [Bug #17827] * * 2021-04-28 [ci skip] * test/ruby/test_fiber.rb: reduce the count of object creation to cause GC ... on Solaris.

For example, suppose a username is `Y\X` and the password is `R%S] ?X`. Properly URL encoded the proxy url would be: http://Y%5CX:R%25S%5D%20%3FX@proxy.example:8000 The resulting proxy auth header should be: `WVxYOlIlU10gP1g=`, but the getters defined by ruby StdLib `URI` return a username `Y%5CX` and password `R%25S%5D%20%3FX`, resulting in `WSU1Q1g6UiUyNVMlNUQlMjAlM0ZY`. As a result the proxy will deny the request. Please note that this is my first contribution to the ruby ecosystem, to standard lib especially and I am not a ruby developer.
