Seems that the same happens still with 2.4.18-26.8.0. SIGIO seems to work as supposed when application is run from console. Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/ |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3b) Gecko/20030119 Description of problem: RH 8.0, Kernel 2.4.14-14 (same with 2.4.18.-19.8.0) In our application we encounter unexpected SIGIO signals. This neither happened on RH 7.3 nor on SuSE 8.1. The application enables SIGIO for stdin to get async notification of keyboard input. However with RH8 SIGIO seems to happen unrelated to stdin. Shortened strace is below: rt_sigaction(SIGIO, {0x8074c90, [], SA_RESTORER|SA_RESTART, 0x42028c48}, NULL, 8) = 0 ... fcntl64(0, F_GETFL) = 0x8002 (flags O_RDWR|O_LARGEFILE) fcntl64(0, F_SETFL, O_RDWR|O_ASYNC|O_LARGEFILE) = 0 ... --- SIGIO (I/O possible) --- select(1024, [0], NULL, NULL, {0, 0}) = 0 (Timeout) sigreturn() = ? (mask now []) write(1, "\33[24;1H\r", 8) = 8 --- SIGIO (I/O possible) --- select(1024, [0], NULL, NULL, {0, 0}) = 0 (Timeout) sigreturn() = ? (mask now []) write(1, "\33[?25h", 6) = 6 --- SIGIO (I/O possible) --- select(1024, [0], NULL, NULL, {0, 0}) = 0 (Timeout) sigreturn() = ? (mask now []) ... Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. run application Actual Results: SIGIO signals related to fd 1 (and fd 0 as well) Expected Results: SIGIO signals related to fd 0 Additional info:
