The latest (2005-03-23 as of this writing) snapshot has some more improvements from Corinna wrt unix domain sockets.
We're coming close to a 1.5.14 release so I would appreciate it if people would try the latest snapshot and report their successes or failures here.
This snapshot is not working as well as the 20050322 snapshot for me. I start ssh-agent, add a key to it, and then run
while true; do date; ssh-add -l; done
in four rxvt windows simultaneously. With the previous snapshot this worked fine. With this snapshot, the loops occasionally all hang up for a while and then several windows print
Error writing to authentication socket. Error writing to authentication socket. The agent has no identities.
instead of the fingerprint for the key as they should.
I tried this with a bash script that would run ssh-add in a loop using strace. I eventually got the same error. I used Ctrl-Z to suspend the scripts and then "kill %1" to kill them. In one window, this caused bash to use 100% of the CPU. When it finally did return to the window, I saw these errors:
8 [main] bash 6920 sig_send: wait for sig_complete event failed, signal
-41, rc 258, Win32 error 0
5 [main] bash 4560 sig_send: wait for sig_complete event failed, signal
-41, rc 258, Win32 error 0"kill %1" and "kill -9 %1" had no effect, bash continued to use 100% of the CPU, and I eventually had to kill bash with the Windows Task Manager.
I did, however, capture strace output from the ssh-add execution that failed and the ssh-agent. They are here
http://mysite.verizon.net/res00a7j/ssh-agent.zip http://mysite.verizon.net/res00a7j/ssh-agent.strace.txt http://mysite.verizon.net/res00a7j/ssh-add.2.strace.txt http://mysite.verizon.net/res00a7j/ssh-add.2.strace.2.txt
(The ssh-agent.strace.txt file is 500MB.)
ssh-add.2.strace.txt is the strace of the execution that failed. ssh-add.2.strace.2.txt is the strace from the previous execution of ssh-add in that window, which succeeded.
I notice the following in ssh-add.2.strace.txt: 385 252744 [main] ssh-add 6592 fhandler_socket::sec_event_connect: sec_event_connect called 1079 253823 [main] ssh-add 6592 fhandler_socket::signal_secret_event: signaled secret_event 9999551 10253374 [main] ssh-add 6592 fhandler_socket::check_peer_secret_event: WFSO rc=258 116 10253490 [main] ssh-add 6592 fhandler_socket::sec_event_connect: accept from unauthorized server 429 10253919 [main] ssh-add 6592 __set_winsock_errno: sec_event_connect:404 - winsock error 10061 -> errno 111

To do two things at once is to do neither.
