Issue #19197 has been reported by AMomchilov (Alexander Momchilov). ---------------------------------------- Feature #19197: Add Exception#root_cause https://bugs.ruby-lang.org/issues/19197 * Author: AMomchilov (Alexander Momchilov) * Status: Open * Priority: Normal ---------------------------------------- ## Description I would like to add a `#root_cause` method to `Exception`. It returns the last exception in linked-list of causality chain, that is, the original exception (whose own `cause` is `nil`). ## Example ```ruby e = begin raise 'a' # This is the root cause rescue => a begin raise 'b' rescue => b begin raise 'c' # This is the outermost cause assigned to `e` rescue => c c end end end p(e) # => #<RuntimeError: c> p(e.cause) # => #<RuntimeError: b> p(e.cause.cause) # => #<RuntimeError: a> p(e.cause.cause.cause) # => nil p(e.root_cause) # => #<RuntimeError: a> p(e.root_cause.cause) # => nil ``` # Motivation There are some kinds of exceptions that can occur all over the place (and might be wrapped by arbitrarily many middlemen), but are attributable to a singular global cause. For example, a database outage could raise exceptions in almost every line of business logic of an app that uses ActiveRecord models. Fundamentally, you wouldn't want an error report for every one of these lines. You'd want to look at the root cause, and bucket all SQL-connection issues into a single report, regardless of where they surface. ### Implementation Draft PR: https://github.com/ruby/ruby/pull/6913 -- https://bugs.ruby-lang.org/

[ruby-core:113332] [Ruby master Bug#19616] Remove ext/readline from Ruby 3.3

Issue #19616 has been reported by hsbt (Hiroshi SHIBATA). ---------------------------------------- Bug #19616: Remove ext/readline from Ruby 3.3 https://bugs.ruby-lang.org/issues/19616 * Author: hsbt (Hiroshi SHIBATA) * Status: Open * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- We still bundled ext/readline that is GNU Readline wrapper. But we already have reline written by pure Ruby. It's time to remove it from Ruby releases. Motivation: * We can skip to install readline or libedit for testing ruby language. * I hope to reduce external dependencies from the perspective of ruby-build maintainer. If users hope to use ext/readline, they can install it with `gem install readline-ext`. -- https://bugs.ruby-lang.org/

[ruby-core:113719] [Ruby master Bug#19703] text/binary mode of parent process fd is not properly inherited on windows
by YO4 (Yoshinao Muramatsu) 31 May '23

31 May '23

Issue #19703 has been reported by YO4 (Yoshinao Muramatsu). ---------------------------------------- Bug #19703: text/binary mode of parent process fd is not properly inherited on windows https://bugs.ruby-lang.org/issues/19703 * Author: YO4 (Yoshinao Muramatsu) * Status: Open * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- Windows OS can't inherit parent process fds greater than 2, but C runtime library support this. https://learn.microsoft.com/en-us/cpp/c-runtime-library/spawn-wspawn-functi… So I made test tool below. This tool opens NUL device several times and create child ruby process that dumps fds' translation mode. ``` c // fdinherit.c : test file descprotor inheritance for windows C runtime #include <stdio.h> #include <stdlib.h> #include <process.h> #include <sys/types.h> #include <sys/stat.h> #include <share.h> #include <fcntl.h> #include <io.h> int main(int argc, char* argv[]) { int fh, count = 0; errno_t err; // child process: read fds and check if it includes "\r" and prints // '.' : read as binary // 't' : read as text // 'F' : open error (no fd?) char rb1[] = "print '012'; 3.upto("; char rb2[] = ") { |n|" "print ((IO.for_fd(n, 'rb').read.include?(13.chr) ? '.' : 't') rescue 'F');" "puts if (n % 10) == 9" "}"; char upto[] = "-4294967295"; // fd max number to test if (argc >= 2) count = atoi(argv[1]); if (count < 3) count = 7; // create crlf file (current directory) system("echo;>crlf.txt"); // open fds to inherit // even fds are text mode, odd fds are binary mode for (int i = 3; i <= count; i++) { err = _sopen_s(&fh, "crlf.txt", _O_RDONLY | ((i & 1) ? _O_BINARY : _O_TEXT), _SH_DENYNO, _S_IREAD | _S_IWRITE); if (err > 0) printf("%d %d\n", err, fh); } // on child side, +1'd fd dump will fail (prints 'F') sprintf_s(upto, sizeof(upto), "%d", count + 1); // on windows, arguments are joined into a string. so below has bad manners, but let me take a few corners. _spawnlp(_P_WAIT, "ruby.exe", "ruby.exe", "-e", "\"", rb1, upto, rb2, "\"", NULL); _close(fh); } ``` As an example, this would display something like this ``` >fdinherit.exe 012.t.t.F >fdinherit.exe 16 012.t.t.t. t.t.t.tF > ``` 0,1,2 are stdin, stdout, stderr fds of 3,5,7,... are inherited as binary mode fds of 4,6,... are inherited as text mode And I found a few things to point out. When I modify ruby part like "IO.for_fd(n, 'r')" / "IO.for_fd(n, 'rt')" / "IO.for_fd(n)", It get result like ```012tttttF```, so translation mode are interprited wrong. The odd thing is that the conversion mode is interpreted as is when "IO.for_fd(n, 'rb')", which I think is the expected behavior when "IO.for_fd(n, 'r')". This tool and ruby.exe each work with a combination of msvcrt 32/64bit and ucrt64, so the C runtime interface seems stable. My understanding is that MRI does not state that it supports inheritance of fds larger than 3 in windows, but it seems to work partially. Are there any chances for improvement? For those who want to follow up: it seems that fds are not inherited via cmd.exe /c -- https://bugs.ruby-lang.org/

Issue #19699 has been reported by edufcarvalho (Eduardo Carvalho). ---------------------------------------- Feature #19699: Need a way to store values like dig https://bugs.ruby-lang.org/issues/19699 * Author: edufcarvalho (Eduardo Carvalho) * Status: Open * Priority: Normal ---------------------------------------- Currently, there is no way to perform a `.store` operation on nested hashes in Ruby as there is for accessing them using `.dig`, so I would like to propose something like: Hash#dig_store(*args, **kwargs, arg = nil), which fills the value at *args with **kwargs if the value at *args is a hash, or with arg if the value is something else. Here are some examples: ```ruby a = {} a.dig_store(:a, :b, :c, :d, 10) => {:a=>{:b=>{:c=>{:d=>10}}}} ``` ```ruby a = {} a.dig_store(:a, :b, :c, :d, a: 10, b: 20, c: 30) => {:a=>{:b=>{:c=>{:d=>{:a=>10, :b=>20, :c=>30}}}}} ``` ```ruby a = {a: {b: {c: "test"}}} a.dig_store(:a, :b, :c, "123") => {:a=>{:b=>{:c=>"123"}}} ``` ```ruby a = {a: {b: {c: {}}} a.dig_store(:a, :b, :c, a: 10, b: 20) => {:a=>{:b=>{:c=>{:a=>10, :b=>20}}}} ``` I'm not that skilled on Ruby (actually a Junior developer), but i'm looking forward to implementing it if the core team approves it -- https://bugs.ruby-lang.org/

[ruby-core:113702] [Ruby master Misc#19122] Use MADV_DONTNEED instead of MADV_FREE when freeing a Fiber's stack

I would prefer to have high performance by default. RSS is a poor measurement IMHO. What about USS and PSS? Are they impacted the same way? Can we subtract the usage that can be later dropped? I mean, as I said in the original description, this is the only part of Ruby that works this way, which makes it surprising. If usage of fibers becomes more common in the wild, or `MADV_FREE` gets used in other areas where Ruby frees memory, then I would predict more reports noting this behaviour. Other languages have reverted their usage of `MADV_FREE` for similar reasons. We can construct another metric that gives us exactly what we want (for cAdvisor, we'd need something like https://github.com/google/cadvisor/issues/3197) but not through PSS or USS; both of those track RSS closely here, at least in my tests. We need to look at either `active_anon + inactive_anon` (for a cgroups `memory.stat` file), or `LazyFree` plus some other things I'm not sure about (for a process's `smaps_rollup`). This won't be the default in most monitoring tools, or in `top` et al, so as I said above, that wouldn't necessarily stop issues coming in. ---------------------------------------- Misc #19122: Use MADV_DONTNEED instead of MADV_FREE when freeing a Fiber's stack https://bugs.ruby-lang.org/issues/19122#change-103348 * Author: smcgivern (Sean McGivern) * Status: Open * Priority: Normal * Assignee: ioquatix (Samuel Williams) ---------------------------------------- I'd like to propose that Ruby stops using MADV_FREE when freeing a Fiber's stack, and switches to using MADV_DONTNEED even when MADV_FREE is supported. MADV_FREE is used in one place in the Ruby codebase, when freeing the stack of a freed Fiber: https://git.ruby-lang.org/ruby.git/tree/cont.c#n683 The comment for `fiber_pool_stack_free` says: ```c // We advise the operating system that the stack memory pages are no longer being used. // This introduce some performance overhead but allows system to relaim memory when there is pressure. ``` Where possible (i.e. on Linux 4.5 and later), `fiber_pool_stack_free` uses `MADV_FREE` over `MADV_DONTNEED`. This has the side effect that memory statistics such as RSS will not reduce until and unless the OS actually reclaims that memory. If that doesn't happen, then the reported memory usage via RSS will be much higher than the 'real' memory usage. If this was pervasive throughtout the Ruby codebase then that would be one thing, but currently this is just for Fiber. This means that: 1. A program that doesn't use Fiber will have somewhat reliable RSS statistics on recent Linux. 2. A program that heavily uses Fiber (such as something using Async::HTTP) will see an inflated RSS statistic. Go made a similar change to the one I'm proposing here for similar reasons: https://github.com/golang/go/issues/42330 > While `MADV_FREE` is somewhat faster than `MADV_DONTNEED`, it doesn't affect many of the statistics that `MADV_DONTNEED` does until the memory is actually reclaimed. This generally leads to poor user experience, like confusing stats in `top` and other monitoring tools; and bad integration with management systems that respond to memory usage. > [...] > I propose we change the default to prefer `MADV_DONTNEED` over `MADV_FREE`, to favor user-friendliness and minimal surprise over performance. I think it's become clear that Linux's implementation of `MADV_FREE` ultimately doesn't meet our needs. As an aside, MADV_FREE was not used in Ruby 3.1 (https://bugs.ruby-lang.org/issues/19101) and I haven't found any bugs filed about this behaviour other than that one. -- https://bugs.ruby-lang.org/
