Hello,
I have a problem with WEBrick on my Gentoo system. Whenever one tries to
launch WEBrick - even with a basic example such as those on the front of the
WEBrick page - it attempts to bind *twice* and thus fails. For example (when
trying to run a Borges example):
[2004-02-05 01:27:38] INFO WEBrick 1.3.1
[2004-02-05 01:27:38] INFO ruby 1.8.0 (2003-08-04) [i686-linux-gnu]
[2004-02-05 01:27:38] WARN TCPServer Error: Address already in use - bind(2)
/usr/lib/ruby/1.8/webrick/server.rb:91:in `listen': Address already in use -
bind(2) (Errno::EADDRINUSE)

from /usr/lib/ruby/site_ruby/1.8/Borges/WEBrick.rb:77:in `start'
from /usr/lib/ruby/site_ruby/1.8/Borges/WEBrick.rb:88
Note that this happens regardless of which port is used. Here is the relevant
part of a strace - note how it first binds successfully and then tries again
and fails. Does the failing _llseek() have anything to do with it perhaps?
bind(3, {sa_family=AF_INET, sin_port=htons(7000),
sin_addr=inet_addr("0.0.0.0")}, 16) = 0
listen(3, 5) = 0
fcntl64(3, F_GETFL) = 0x2 (flags O_RDWR)
fstat64(3, {st_mode=S_IFSOCK|0777, st_size=0, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =

fcntl64(3, F_GETFD) = 0
gettimeofday({1075940535, 686187}, NULL) = 0
socket(PF_INET6, SOCK_STREAM, 6) = 4
setsockopt(4, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
bind(4, {sa_family=AF_INET6, sin6_port=htons(7000), inet_pton(AF_INET6, "::",
&sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = -1 EADDRINUSE (Address
already in use)
I have not been able to reproduce this on another system (running FreeBSD).
Has anyone seen this? It occurrs with both Ruby 1.8.0 and 1.8.1.
