Subject: [ruby-core:117305] [Ruby master Bug#20390] Issue with StringIO and chilled strings
Date: Sun, 24 Mar 2024 15:46:18 +0000 (UTC) [thread overview]
Message-ID: <redmine.issue-20390.20240324154618.443@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-20390.20240324154618.443@ruby-lang.org
Issue #20390 has been reported by mdalessio (Mike Dalessio).
----------------------------------------
Bug #20390: Issue with StringIO and chilled strings
https://bugs.ruby-lang.org/issues/20390
* Author: mdalessio (Mike Dalessio)
* Status: Open
* ruby -v: ruby 3.4.0dev (2024-03-23T16:40:17Z master 8265a7531f) [x86_64-linux]
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
StringIO doesn't appear to handle chilled strings in a backwards-compatible way after 12be40ae
```ruby
require "stringio"
sio = StringIO.new("")
sio.write("hello")
```
When not specifying a value for `frozen-string-literal`, the empty string is chilled so I would expect to get a warning but also expect the write to complete.
Instead, the write fails as if the string is frozen:
```
ruby 3.4.0dev (2024-03-23T16:40:17Z master 8265a7531f) [x86_64-linux]
./issue-stringio-frozen.rb:8:in 'StringIO#write': not opened for writing (IOError)
from ./issue-stringio-frozen.rb:8:in '<main>'
```
