...pies of "The Design and Implementation of the 4.4BSD Operating System" as well as "Unix Internals: The New Frontiers". Specifically, pages 111-112 and 344 of the former and page 108 of the latter. It comes down to this: - The 4.4BSD tty and pty drivers send SIGHUP followed by SIGCONT (for stopped processes) to all orphaned process groups with a given tty/pty association when the session leader exits (TDI44BSDOS states that POSIX and 4.4BSD do this) - and any open file descriptors referring to the tty/pty in any processes that choose to continue running are revoke...

Hi, A developper of MandrakeSoft needed for some reason to ameliorate ogg123 in a way: with the patch when you issue a Ctrl+Z (suspending the app) the dsp is freed. Ofcourse the app can still continue when SIGCONT is received. Apparently he chose to separate the actual code into more functions. Please note that this code uses local functions, it thus needs gcc to compile. -=-=-- --- vorbis-tools-1.0beta3/ogg123/ogg123.c.pix Thu Dec 28 17:46:53 2000 +++ vorbis-tools-1.0beta3/ogg123/ogg123.c Fri Dec 29 07:...

Suppose I have a USDT probe in Firefox and that I''m trying to catch the startup with a probe like this: proc:::exec-success /execname == "firefox-bin"/ { start = timestamp; } and stop tracing when Firefox hits this USDT probe: mozilla:::main-entry { exit(0); } How do I put the running firefox-bin into "trace mode" so that my USDT probe fires? Thanks, Joel

I am playing with tcl/tk on centso 4.2. I am trying to trap a signal and I get an error that invalid command name signal. My line is: signal trap SIGCONT ReadMessage where ReadMessage is a proc Is centos 4.2 missing a package or some thing for tcl? The example I found did not mention any restrictions. Any ideas, thank you. Jerry -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.centos.org/pipermail/...

One of our backend pop/imap-server running dovecot v1.2.16 experienced some problems yesterday. It suddenly couldn't authenticate users anymore, flooding the logs with: pop3-login: Disconnected (auth failed, 1 attempts): user=<user1 at example.com>, method=PLAIN, rip=192.168.42.15, lip=192.168.42.28 The problem seemed to start with this log entry: Mar 29 18:57:21 popimap1 dovecot:

So i sent a SIGCONT to the sshd server, and the ssh come back alive. We debugged into the code, found out that everytime the ssh did check the variable "keep_alive_timeouts" with the ServerAliveCountMax value after ServerAliveInterval seconds to see if keep_alive_timeouts > ServerAliveCountMax, if so , s...

...et of the signals you might want to *send* with a "signal" channel request. In particular, if you want to support sending all of the signals that can be generated by keyboard input, the suspend character is missing (SIGTSTP). I guess we can live without most of the others, but possibly SIGCONT and SIGSTOP might be useful too. I think TSTP should be part of the base spec, (and not an xx at foo.bar extension) otherwise this channel request can't fulfill the most basic need (propagating signals from a terminal to an app). -- -- Howard Chu CTO, Symas Corp. http://www....

Patch registers SIGTSTP hook where it sends reset terminal color control sequence using write and fsync. Handler is installed only if signal is not being ignored. Patch uses rl_free_line_state and rl_cleanup_after_signal to unhook readline from terminal, then it calls original TSTP handler using approach in URL below and again hooks readline using rl_reset_after_signal. Handling is based on code
