I think my failed patch exposes a bug with lazy sweep + rb_fstring.

ruby-core #57786
Issue #8977 has been updated by headius (Charles Nutter).
Actually, I'm getting pretty down on having the fstring cache at all. It seems like if we want a string pool, it should be via a library. Adding something into Ruby that pools strings for you just seems like asking for trouble, either due to GC overhead (cleaning up that hash for tons of transient frozen strings) and semantics (abuse of #frozen or #freeze to do pooling implicitly).
----------------------------------------
Feature #8977: String#frozen that takes advantage of the deduping
https://bugs.ruby-lang.org/issues/8977#change-42393
Author: sam.saffron (Sam Saffron)
Status: Open
Priority: Normal
Assignee:
Category:
Target version: current: 2.1.0
During memory profiling I noticed that a large amount of string duplication is generated from non pre-determined strings.
Take this report for example https://gist.github.com/SamSaffron/6789005 (generated using the memory_profiler gem that works against head)
">=" x 4953
/Users/sam/.rbenv/versions/2.1.0-dev/lib/ruby/2.1.0/rubygems/requirement.rb:93 x 4535
This string is most likely extracted from a version.
Or
"/Users/sam/.rbenv/versions/2.1.0-dev/lib/ruby/gems" x 5808
/Users/sam/.rbenv/versions/2.1.0-dev/lib/ruby/gems/2.1.0/gems/activesupport-3.2.12/lib/active_support/dependencies.rb:251 x 3894
A string that can not be pre-determined.
----
It would be nice to have
"hello,world".split(",")[0].frozen.object_id == "hello"f.object_id
Adding #frozen will give library builders a way of using the de-duping. It also could be implemented using weak refs in 2.0 and stubbed with a .dup.freeze in 1.9.3 .
Thoughts ?
