Bug #21

should terminate @receiver_thread of Net::IMAP safely

Added by shugo (Shugo Maeda) over 9 years ago. Updated almost 7 years ago.

Status:
Closed
Priority:
Normal
Target version:
[ruby-dev:34881]

Description

=begin
@receiver_thread of Net::IMAP may be terminated by exception,
and this causes the process termination if Thread.abort_on_exception is true.

Then Net::IMAP#disconnect does not call @receiver_thread.join if TCPSocket#close
raises an exception.

Added by shyouhei (Shyouhei Urabe) about 2 months ago

obj_info() assumes the given object is alive. OTOH
gc_writebarrier_incremental is called before or in middle of
object initialization. Can casue SEGV.
