[ruby-core:118241] [Ruby master Feature#18773] deconstruct to receive a range
by Eregon (Benoit Daloze) 07 Jun '24

07 Jun '24

Issue #18773 has been updated by Eregon (Benoit Daloze). FWIW I think CRuby currently support subclassing Array and redefining `[]` and pattern matching will call that on CRuby, maybe it can be used for this purpose. I don't think it's a good idea to rely on this behavior though, it might change. For example that doesn't work on TruffleRuby, which currently always uses standard `Array#[]` from pattern matching. ---------------------------------------- Feature #18773: deconstruct to receive a range https://bugs.ruby-lang.org/issues/18773#change-108740 * Author: kddnewton (Kevin Newton) * Status: Rejected * Assignee: ktsj (Kazuki Tsujimoto) ---------------------------------------- Currently when you're pattern matching against a hash pattern, `deconstruct_keys` receives the keys that are being matched. This is really useful for computing expensive hashes. However, when you're pattern matching against an array pattern, you don't receive any information. So if the array is expensive to compute (for instance loading an array of database records), you have no way to bail out. It would be useful to receive a range signifying how many records the pattern is specifying. It would be used like the following: ```ruby class ActiveRecord::Relation def deconstruct(range) (loaded? || range.cover?(count)) ? records : nil end end ``` It needs to be a range and not just a number to handle cases where `*` is used. You would use it like: ```ruby case Person.all in [] "No records" in [person] "Only #{person.name}" else "Multiple people" end ``` In this way, you wouldn't have to load the whole thing into memory to check if it pattern matched. The patch is here: https://github.com/ruby/ruby/pull/5905. -- https://bugs.ruby-lang.org/

Issue #18773 has been updated by Eregon (Benoit Daloze). The implementation of pattern matching needs to read at indices from the return value of `deconstruct`, but `Enumerable` doesn't have `[]` or `at` or anything like that. So I think it is difficult to support and could very well end up making pattern matching slower. There is a similar issue in the issue description, it would prevent caching the result of `deconstruct`, as already pointed out. I think pattern shouldn't do too crazy things (like calling `each` with a block behind the scenes), I think simple is good. ---------------------------------------- Feature #18773: deconstruct to receive a range https://bugs.ruby-lang.org/issues/18773#change-108739 * Author: kddnewton (Kevin Newton) * Status: Rejected * Assignee: ktsj (Kazuki Tsujimoto) ---------------------------------------- Currently when you're pattern matching against a hash pattern, `deconstruct_keys` receives the keys that are being matched.

[ruby-core:118238] [Ruby master Feature#6648] Provide a standard API for retrieving all command-line flags passed to Ruby
by Dan0042 (Daniel DeLorme) 07 Jun '24

07 Jun '24

Issue #6648 has been updated by Dan0042 (Daniel DeLorme). > As you see there is no Windows API that takes `char**`. We cannot safely pass through what we have. You have to concatenate them into one argument string (`LPWSTR lpCommandLine`), with proper escaping of whitespace etc. But this issue is not specific to `RbConfig.ruby_args` is it? You have to do the concatenation in exec/system anyway; `RbConfig.ruby_args` will not change this situation either for better or worse. > Because process arguments come from out of the process itself by nature, there is no guarantee that they are written by good will. Can you explain that one? I don't understand how valid ruby options like `--enable=jit` could be "not written by good will". ---------------------------------------- Feature #6648: Provide a standard API for retrieving all command-line flags passed to Ruby https://bugs.ruby-lang.org/issues/6648#change-108737 * Author: headius (Charles Nutter) * Status: Assigned * Assignee: matz (Yukihiro Matsumoto) ---------------------------------------- Currently there are no standard mechanisms to get the flags passed to the currently running Ruby implementation. The available mechanisms are not ideal: * Scanning globals and hoping they have not been tweaked to new settings * Using external wrappers to launch Ruby * ??? Inability to get the full set of command-line flags, including flags passed to the VM itself (and probably VM-specific) makes it impossible to launch subprocess Ruby instances with the same settings. A real world example of this is "((%bundle exec%))" when called with a command line that sets various flags, a la ((%jruby -Xsome.vm.setting --1.9 -S bundle exec%)). None of these flags can propagate to the subprocess, so odd behaviors result. The only option is to put the flags into an env var (((|JRUBY_OPTS|)) or ((|RUBYOPT|))) but this breaks the flow of calling a simple command line. JRuby provides mechanisms to get all its command line options, but they require calling Java APIs from Ruby's API set. Rubinius provides its own API for accessing comand-line options, but I do not know if it includes VM-level flags as well as standard Ruby flags. I know there is a (({RubyVM})) namespace in the 2.0 line. If that namespace is intended to be general-purpose for VM-level features, it would be a good host for this API. Something like... ``` class << RubyVM def vm_args; end # returns array of command line args *not* passed to the target script def script; end # returns the script being executed...though this overlaps with $0 def script_args; end # returns args passed to the script...though this overlaps with ARGV, but that is perhaps warranted since ARGV can be modified (i.e. you probably want the original args) end ``` -- https://bugs.ruby-lang.org/

Issue #6648 has been updated by Dan0042 (Daniel DeLorme). shyouhei (Shyouhei Urabe) wrote in #note-26: > In short the problem we see is feeding strings from untrusted sources to generic `Kernel#exec`. Sounds ultra risky, no? It also sounds nothing like what this proposal is about. If the current script was executed with `ruby --enable=jit foo.rb` then it is, by definition, safe to run `exec("ruby", "--enable=jit", "foo.rb")` It's already possible to run `exec("ruby", "foo.rb")`; changing it to `exec("ruby", *RbConfig.ruby_args, "foo.rb")` does not reduce security, in fast it **increases** security. ---------------------------------------- Feature #6648: Provide a standard API for retrieving all command-line flags passed to Ruby https://bugs.ruby-lang.org/issues/6648#change-108736 * Author: headius (Charles Nutter) * Status: Assigned * Assignee: matz (Yukihiro Matsumoto) ---------------------------------------- Currently there are no standard mechanisms to get the flags passed to the currently running Ruby implementation.

[ruby-core:118230] [Ruby master Feature#6648] Provide a standard API for retrieving all command-line flags passed to Ruby
by shyouhei (Shyouhei Urabe) 07 Jun '24

07 Jun '24

Issue #6648 has been updated by shyouhei (Shyouhei Urabe). In short the problem we see is feeding strings from untrusted sources to generic `Kernel#exec`. Sounds ultra risky, no? Let's not do so. If what is needed is just launching a ruby process, we could perhaps design a workaround. ---------------------------------------- Feature #6648: Provide a standard API for retrieving all command-line flags passed to Ruby https://bugs.ruby-lang.org/issues/6648#change-108725 * Author: headius (Charles Nutter) * Status: Assigned * Assignee: matz (Yukihiro Matsumoto) ---------------------------------------- Currently there are no standard mechanisms to get the flags passed to the currently running Ruby implementation. The available mechanisms are not ideal: * Scanning globals and hoping they have not been tweaked to new settings * Using external wrappers to launch Ruby * ??? Inability to get the full set of command-line flags, including flags passed to the VM itself (and probably VM-specific) makes it impossible to launch subprocess Ruby instances with the same settings. A real world example of this is "((%bundle exec%))" when called with a command line that sets various flags, a la ((%jruby -Xsome.vm.setting --1.9 -S bundle exec%)). None of these flags can propagate to the subprocess, so odd behaviors result. The only option is to put the flags into an env var (((|JRUBY_OPTS|)) or ((|RUBYOPT|))) but this breaks the flow of calling a simple command line. JRuby provides mechanisms to get all its command line options, but they require calling Java APIs from Ruby's API set. Rubinius provides its own API for accessing comand-line options, but I do not know if it includes VM-level flags as well as standard Ruby flags. I know there is a (({RubyVM})) namespace in the 2.0 line. If that namespace is intended to be general-purpose for VM-level features, it would be a good host for this API. Something like... ``` class << RubyVM def vm_args; end # returns array of command line args *not* passed to the target script def script; end # returns the script being executed...though this overlaps with $0 def script_args; end # returns args passed to the script...though this overlaps with ARGV, but that is perhaps warranted since ARGV can be modified (i.e. you probably want the original args) end ``` -- https://bugs.ruby-lang.org/
