Issue #20330 has been reported by l33tname (Sir l33tname). ---------------------------------------- Bug #20330: [BUG] Segmentation fault at 0xffffffffffffffff https://bugs.ruby-lang.org/issues/20330 * Author: l33tname (Sir l33tname) * Status: Open * ruby -v: 3.3.0 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I get a segfault from ruby on fly.io (a platform to run full stack apps). As you can see from the stacktracke im using a jemalloc version but im getting the same crash with the ruby:3.3.0-slim docker image. (Thats the docker file: https://github.com/Binaergewitter/serious-bg/blob/be890bf6af110b02f22f359d3… based on quay.io/evl.ms/fullstaq-ruby:3.3.0-jemalloc-slim) Reverting back to ruby 3.2.3 solved the issue for now: https://github.com/Binaergewitter/serious-bg/commit/4eed4119706303383ce5994… I was not able to reproduce it locally. But the application is open source -> https://github.com/Binaergewitter/serious-bg ``` 2024-03-09T09:31:07Z app[3d8d7d99f40128] iad [info][ 0.037737] Spectre V2 : WARNING: Unprivileged eBPF is enabled

Also seeing this on fly.io, but only when running `fly console` which boots up a machine, and then runs bin/rails console.

Issue #20384 has been reported by kddnewton (Kevin Newton). ---------------------------------------- Feature #20384: RubyVM::InstructionSequence.{new,compile} use --parser option https://bugs.ruby-lang.org/issues/20384 * Author: kddnewton (Kevin Newton) * Status: Open ---------------------------------------- Right now we have `RubyVM::InstructionSequence.compile` and `RubyVM::InstructionSequence.compile_prism`. We introduced this API in order to properly test the integration, even when running with `--parser=parse.y`. I'm running into issues, however, when tests are comparing between `eval` and `RubyVM::InstructionSequence.new`. The latter always uses `parse.y`, even if `--parser=prism` is passed on the command line. I would like to change that so that `RubyVM::InstructionSequence.{new,compile}` respects the `--parser` option so that it's consistent. Would this change be okay? It would only impact processes with `--parser=prism`, so I don't imagine there's any kind of risk here. -- https://bugs.ruby-lang.org/

Issue #20400 has been reported by kddnewton (Kevin Newton). ---------------------------------------- Bug #20400: Nested BEGIN{} execution order https://bugs.ruby-lang.org/issues/20400 * Author: kddnewton (Kevin Newton) * Status: Open * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- Right now there are specs for the order in which `BEGIN{}` should be executed, which is the order they appear in the file. For example: ```ruby BEGIN { print "1" } print "4" BEGIN { print "2" } print "5" BEGIN { print "3" } ``` should output "12345". However, I couldn't find any tests/specs on what happens when `BEGIN{}` is nested. The order appears to be somewhat confusing, so I wanted to clarify if it was intentional or a bug. For example: ```ruby BEGIN { print "1" BEGIN { print "2" } } ``` prints "21", and: ```ruby BEGIN { print "1" BEGIN { print "2" } BEGIN { print "3" } } ``` prints "231", and finally: ```ruby BEGIN { print "1" BEGIN { print "2" BEGIN { print "3" } } BEGIN { print "4" } } ``` prints "3241". Is this intentional? -- https://bugs.ruby-lang.org/

[ruby-core:117324] [Ruby master Feature#20394] Add an offset parameter to `String#to_i`
by byroot (Jean Boussier) 28 Mar '24

28 Mar '24

Issue #20394 has been reported by byroot (Jean Boussier). ---------------------------------------- Feature #20394: Add an offset parameter to `String#to_i` https://bugs.ruby-lang.org/issues/20394 * Author: byroot (Jean Boussier) * Status: Open ---------------------------------------- ### Context I maintain the `redis-client` gem, and it comes with an optional swapable implementation in C that binds the `hiredis` C client, [which used to performs up to 5 times faster in some cases](https://github.com/redis-rb/redis-client/commit/9fabd57c6786a03fe0c6…. I recently paired with @tenderlovemaking to try to close this gap, or even try to make the pure Ruby version faster, and we came up with several optimizations that now almost make both version on par (assuming YJIT is enabled). An important source of performance loss, is that the Redis protocol is line based and to parse it in Ruby requires to slice a lot of small strings from the buffer. To give an example, here's how an Array with two String (`["foo", "plop"]`) is serialized in RESP3 (Redis protocol): ``` *2\r\n $3\r\n foo\r\n $4\r\n plop\r\n ``` From this you can understand that a big hotspot in the parser is essentially `Integer(gets)`. With @tenderlovemaking we managed to get [a fairly significant perf boost](https://github.com/redis-rb/redis-client/commit/41b3abe94243d2598211… by avoiding these string allocation using `String#getbyte` and [basically implementing a rudimentary `String#to_i(offset: )` in Ruby](https://github.com/redis-rb/redis-client/commit/41b3abe94243d2598211d…. But while the gains are huge with YJIT enabled, they are much more tame with the interpreter. And it feels a bit wrong to have to implement this sorts of things for performance reasons. ### `String#to_i(offset: )` Similar to `String#unpack(offset:)` ([Feature #18254]), I believe `String#to_i(offset: )` would be useful. ### Alternative new `String#unpack` format Another possibility would be to add a new format to `String#pack` `String#unpack` for decimal numbers. It sounds a bit weird at first, but given it supports things like Base64 and hexadecimal, perhaps it's not that much of a stretch? -- https://bugs.ruby-lang.org/

[ruby-core:117300] [Ruby master Feature#19057] Hide implementation of `rb_io_t`.
by ioquatix (Samuel Williams) 28 Mar '24

28 Mar '24

Issue #19057 has been updated by ioquatix (Samuel Williams). > Why don't you reconsider the "nested public interface" approach? My assessment of this approach is that it would require a rewrite of all internal code that accesses `rb_io_t` internals. Rewriting code isn't a problem, but it takes a lot of time and effort that I don't have in abundance right now. Additionally, it's still only a partial solution. One of the issues is accessing the file descriptor directly and the handling of `IO#close` from a different thread/fiber. Using the file descriptor directly can be problematic. > Ruby lost numerous users due to a never-ending stream of incompatibilities introduced every year. Compatibility and progress are always something to balance out. I think on the whole, Ruby does a pretty decent job at it. Lack of forward progress also causes users to look elsewhere as the language stagnates. So this isn't just. a matter of "preserve compatibility at all costs", as those costs will be the same. The hard part is finding the middle ground of compatibility and progress. Both compatibility at any cost, and progress at any cost, are naive statements. ---------------------------------------- Feature #19057: Hide implementation of `rb_io_t`. https://bugs.ruby-lang.org/issues/19057#change-107442 * Author: ioquatix (Samuel Williams) * Status: Assigned * Assignee: ioquatix (Samuel Williams) * Target version: 3.4 ---------------------------------------- In order to make improvements to the IO implementation like <https://bugs.ruby-lang.org/issues/18455>, we need to add new fields to `struct rb_io_t`. By the way, ending types in `_t` is not recommended by POSIX, so I'm also trying to rename the internal implementation to drop `_t` where possible during this conversion. Anyway, we should try to hide the implementation of `struct rb_io`. Ideally, we don't expose any of it, but the problem is backwards compatibility. So, in order to remain backwards compatibility, we should expose some fields of `struct rb_io`, the most commonly used one is `fd` and `mode`, but several others are commonly used. There are many fields which should not be exposed because they are implementation details. ## Current proposal The current proposed change <https://github.com/ruby/ruby/pull/6511> creates two structs: ```c // include/ruby/io.h #ifndef RB_IO_T struct rb_io { int fd; // ... public fields ... }; #else struct rb_io; #endif // internal/io.h #define RB_IO_T struct rb_io { int fd; // ... public fields ... // ... private fields ... }; ``` However, we are not 100% confident this is safe according to the C specification. My experience is not sufficiently wide to say this is safe in practice, but it does look okay to both myself, and @Eregon + @tenderlovemaking have both given some kind of approval. That being said, maybe it's not safe. There are two alternatives: ## Hide all details We can make public `struct rb_io` completely invisible. ```c // include/ruby/io.h #define RB_IO_HIDDEN struct rb_io; int rb_ioptr_descriptor(struct rb_io *ioptr); // accessor for previously visible state. // internal/io.h struct rb_io { // ... all fields ... }; ``` This would only be forwards compatible, and code would need to feature detect like this: ```c #ifdef RB_IO_HIDDEN #define RB_IOPTR_DESCRIPTOR rb_ioptr_descriptor #else #define RB_IOPTR_DESCRIPTOR(ioptr) rb_ioptr_descriptor(ioptr) #endif ``` ## Nested public interface Alternatively, we can nest the public fields into the private struct: ```c // include/ruby/io.h struct rb_io_public { int fd; // ... public fields ... }; // internal/io.h #define RB_IO_T struct rb_io { struct rb_io_public public; // ... private fields ... }; ``` ## Considerations I personally think the "Hide all details" implementation is the best, but it's also the lest compatible. This is also what we are ultimately aiming for, whether we decide to take an intermediate "compatibility step" is up to us. I think "Nested public interface" is messy and introduces more complexity, but it might be slightly better defined than the "Current proposal" which might create undefined behaviour. That being said, all the tests are passing. -- https://bugs.ruby-lang.org/

[ruby-core:117351] embedd ruby 3.3.0 - unknown Time.now class method
by fiesta06 27 Mar '24

Hi, I want to embedd the ruby 3.3.0 interpreter into my application by using the following code: int error, n; static char* args[] = {}; n = 0; ruby_sysinit(&n, (char ***)&args); RUBY_INIT_STACK; ruby_init(); ruby_init_loadpath(); rb_eval_string_protect("p Time.now", &error); if(error) { rb_eval_string("p :ERROR"); } In principle it does work. However, the Time class is missing the now method, thus a :ERROR is printed. What it missing in the above code ?
