Problem with Thread's memory (possible bug)

Ruby
1

Hi all.

Some time ago I’ve started thread named “Memory crush somewhere in
Socket”
with no results. No I can describe the problem more correctly and in
details.

First of all: Windows XP with ruby1.9, RUBY_PLATFORM = i386-mswin32_71

I have a window, and dispatch all keyboard events to Ruby’s block.
All works good, except Ruby’s Threads. When I do anything like just
Thread.new{} in my keyboard handling block, I have corrupted memory and
entire program crashed soon.

How can I debug (or just walk around) this problem?

Thanks.

First of all, try to reproduce in Ruby 1.8.5.

Unfortunately, I can’t do it easy.
My window library extensively uses instance_exec. Reproducing without
this
library would be a pain.

First, mere 1.9 does not mean anything. Specify the date.
Full ruby -v line is better.

Besides that, is it possible to supply error reproducing code?

Much better.

Hmm. Does you custom UI library tweaks system stack in any way? Ruby
threads does evil things with setjmp/longjmp. They may not co-exist
with other library with similar technique.

I don’t know definitely, because “my” library is really third-party
closed-source DLL with my C/C++ wrapper. My wrapper does no evil, what
about HTMLayout (third-party library), I’ll ask the author today or
tomorrow and do the further investigation.

Thanks!

Sorry :frowning:
There was words “today’s version” in my platform description, but I’ve
deleted them before send message.
It was Ruby1.9-today, downloaded yesterday.

ruby 1.9.0 (2006-11-04) [i386-mswin32_71]

Possible, but not very useful, as there is custom UI library used.
Here is it:

require ‘lib/config’

require ‘htmr’
require ‘htmr/load’
require ‘htmr/extend’
require ‘htmr/events’

MAIN_HTMR = File.join(HTMR_PATH, ‘nanobrowser.htmr’)

win = Htmr::Window.create_from_file(MAIN_HTMR, ‘NanoBrowser’)

Htmr::App::main_window = win

include Htmr::Keys
win.get(‘#url’).on_key_down(ENTER) do
Thread.new{} #HERE’s thread usage!
end

win.show

Htmr::App::run

inside ‘lib/config’ there is:

$:.unshift File.expand_path(File.dirname(FILE))
$:.unshift File.expand_path(File.join(File.dirname(FILE),
“vendors”))
require ‘vendors’

DLL_PATH = File.expand_path(File.join(File.dirname(FILE), ‘…’,
‘bin’))

ENV[‘PATH’] += “;” + DLL_PATH

HTMR_PATH = File.join(File.expand_path(File.dirname(FILE)), ‘…’,
‘htmr’)

All htmr/* files is UI library.

If I’ll comment “HERE’s thread” line, all works fine. I use my library
till
last 2 month inside rather complicated software, and there was almost no
problems.

Thanks.

Matz, there is no setjmp/longjmp or something like this in my UI
library.
I’d be grateful for any other advices, how to catch this.
