I've finally found a way to reproduce the following old bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=502222
(it still occurs with svn 1.9.4). Make SVN_SSH point to the following script: ---------------------------------------- #!/bin/sh sleep 10 & while true; do :; done ---------------------------------------- Do a "svn up" and Ctrl-C. Then svn terminates only when "sleep" terminates. If I redirect the output of "sleep" to /dev/null, like that: ---------------------------------------- #!/bin/sh sleep 10 > /dev/null & while true; do :; done ---------------------------------------- then the problem disappears, i.e. Ctrl-C immediately terminates svn. Note: The reason this problem occurs in my case is that my script does "ssh -fMN ..." (which corresponds to the "sleep ... &" here) when the control socket doesn't exist. The infinite loop corresponds to the real ssh that would freeze due to a network problem. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
