Description:

Since one of the latest updates, every time ruby is run, it runs several find processes whith at least one over the current working dir.
If that happens to be /, or a slow disk/network mount, this adds a considerable (and unneccessary?) startup delay.
Even when seemingly no special stuff is used (just 'puts' a string, like below).

I noticed, since I happen to have dirs inaccessable to the current user in my home, such as a chroot env, for example
and the find process reported "Permission denied" errors as seen below.
Also a pacman hook that uses ruby and happens to have / as working dir, took a long time and showed errors from find about permission errors in /proc and /run !

If I comment out the line with the find command in /usr/lib/ruby/gems/3.0.0/specifications/default/did_you_mean-1.6.1.gemspec the problem goes away.


No idea if this is an upstream problem or a packaging issue, but since it started after that whole "bundled gems" restructuring,
that has happened recently or is still happening (?), I'd guessed I better report this here first.

Additional info:
* package version(s)

% pacman -Q ruby ruby-did_you_mean
ruby 3.0.4-14
ruby-did_you_mean 1.6.1-2

Steps to reproduce:

% mkdir inaccessible
% chmod 000 inaccessible
% ruby -e 'puts "foo"'
find: ‘./inaccessible’: Permission denied
foo

% time ruby -e 'puts "foo"'
find: ‘./inaccessible’: Permission denied
foo

% sudo vim /usr/lib/ruby/gems/3.0.0/specifications/default/did_you_mean-1.6.1.gemspec

% time ruby -e 'puts "foo"'
foo
