There is no such requirement as rubygems.rb in that folder being written to= . I run locked down lxc containers on a daily basis that have no such writi= ng ability (read only roots) and ruby works just fine. That folder is also = not generally writeable on my systems for a standard user either even if th= e root is not read only. I'm also generally unaware (and I could be very wrong) but there is no "lis= t" of installed gems anywhere that I can find. I don't believe you are barking up the correct tree here. The file you mention is required to be readable because it is the core of t= he rubygems module - but there is nothing written to that file at all. ---------------------------------------- Bug #15787: rubygems.rb on read-only volume https://bugs.ruby-lang.org/issues/15787#change-77756 * Author: extrowerk (Zolt=E1n Mizsei) * Status: Open * Priority: Normal * Assignee: = * Target version: = * ruby -v: ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-haiku] * Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- On Haiku the package management just virtually extracts/populates the files= , and as it doesn't have write-overlay feature, the populated files are rea= d-only. Issue: Ruby has to maintain a list of installed gems in a single file, in r= ubygems.rb. Ruby stats this file, and bails out if it is read-only: ``` ~ =BB ruby --version ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-haiku] ~ =BB ruby Traceback (most recent call last): 1: from :2:in `' :2:in `require': Operation not supported -- /boot/sys= tem/lib/ruby/2.6.0/rubygems.rb (LoadError) ~ =BB ls -la /boot/system/lib/ruby/2.6.0/rubygems.rb -r--r--r-- 1 user root 36970 m=E1rc. 6 10:01 /boot/system/lib/ruby/2.6.0/r= ubygems.rb ~ =BB uname -a Haiku shredder 1 hrev53091 Apr 22 2019 22:17:21 x86_64 x86_64 Haiku ``` = The 2.2.x branch was not affected, but since 2.3 every version have this pr= oblem. Happens here: https://github.com/ruby/ruby/blob/trunk/ruby.c#L2098 Either it has to create this file somewhere in non-packaged (this is the wr= iteable folderstructure) and hope it won't get out of sync when pkgman (pac= kage updater software) updates Ruby packages, or it has to be fixed to enum= erate them directly by examining the directories. The fact that this file is located in a packaged tree also hints that Ruby = will probably want to also use packaged location for manual gems installs, = which obviously won't work either. Question: is it possible to force/instrument ruby to use a user-specific "r= ubygems.rb" if the system one read only? Probably this problem exists on other platforms too, where the user doesn't= have write-right to this file. How is it handled? Thank You! -- = https://bugs.ruby-lang.org/ Unsubscribe:
