comp.lang.ruby

actual debian ruby packages are unuseable with tk

Ferenc Engard

Dear debian ruby package maintainers,

I just tell here, that both the 1.6.8-6 and the 1.8.0-2 ruby packages
are break on this simple script:

-----------------------
require 'tk.rb'

begin
raise "blah"
rescue
puts "rescued"
end
-----------------------

This script will never return with both versions of ruby. I am waiting
on the new versions. (I hope the bugfix was backported to 1.6.8; if not,
then I wait for the 1.8.0 version of DBI, too...)

Regards,
Circum

Hm, hangs for me with 1.6.8-7, too. Ruby/Tk experts around?

Debian packages of DBI for Ruby 1.8.0 are already waiting in queue to
Debian/unstable. I will also put it up on people.d.o soon, as I think it
will take a couple more weeks to finish with Ruby 1.6 -> 1.8 transition.

Not expert but apparently there is a dead-lock : not really sure if the
problem is in tcl

http://people.debian.org/...

If you''re too lazy to fire up a browser, here is a relevant excerpt:

----------------------------------------------------------------------
Ruby 1.8.0 backport to Debian 3.0r1/woody by Vladimir Shahov:

deb http://people.debian.org/... stable main
deb-src http://people.debian.org/... stable main

apt-get install ruby1.8

----------------------------------------------------------------------
Debian Ruby Policy-compliant packages of YAML4R, Ruby/DBI, PostgreSQL
(from Taku YASUI) and MySQL modules for Ruby 1.6 and 1.8:

deb http://people.debian.org/... unstable main
deb-src http://people.debian.org/... unstable main

apt-get install libyaml1.6-ruby libdbi-ruby libdbd-pg-ruby1.6 libdbd-pg-ruby1.8 libdbd-mysql-ruby1.6 libdbd-mysql-ruby1.8 libdbd-sqlite-ruby1.6 libdbd-sqlite-ruby1.8

I''ve checked these packages against Samizdat (which requires yaml and
dbi/pg), and it works fine both with 1.6 and with 1.8 versions.

Enjoy!

I have the strong feeling that it is the same problem which Hidetoshi
explained in <20030908.134849.41649609.nagai@ai.kyutech.ac.jp>. (8.
Sep, "2 questions about TkVariable and ruby/tk" thread).

Typo: should be libyaml-ruby1.6, of course.

Well, run your script under gdb, i.e.

gdb ruby
(gdb) r name_of_your_script.rb

when it hang, send it ^C (control-C) and run the command `bt'' to see what
it do

(gdb) bt

and send all output (specifically if it create POSIX thread)

I think it is quite impossible if I want to work with debian binaries.
ruby/tk depends on libtcltk-ruby debian package, and in this package
tcltklib.so links with libtk8.4.so.0. I do not want to recompile
libtcltk-ruby.

PS: I never debugged multi-threaded programs, but here is some more gdb
output:

0x404e7b88 in __pthread_sigsuspend () from /lib/libpthread.so.0

Couldn''t get registers: No such process.

After this it repeats this same pattern, and ''bt'' returns the same error
message.

Can you try : needless to say that it''s just a "bricolage" before waiting
the correction :-(((

require ''tk.rb''
trap 0, proc { sleep 0.1 }

begin
raise "blah"
rescue
puts "rescued"
end
