All, When logging into an HP-UX 10.2 system from a Windows NT machine running Cygwin and openssh 2.9p2, control-c sends a sigint to the ssh client on the NT system, thus killing the ssh process. Interestingly enough, this behavior is only observed when using X11 forwarding. I can eliminate the behavior by changing clientloop.c to ignore SIGINT (signal(SIGINT, SIG_IGN) ) but then I'm bak to

Yeah, I get that they are async. What happens is that the background process is not doing anything when the process gets a SIGINT. I.e. the background process is just listening on its standard input. AFAICT for an interactive process such a SIGINT is just swallowed, with a newline outputted to the terminal. But apparently, for this background process, it is not swallowed, and it is triggered

Hi All, I realize that this is not a really nice reprex, but anyone has an idea why a background R session would "remember" an interrupt (SIGINT) on Unix? rs <- callr::r_session$new() rs$interrupt() # just sends a SIGINT #> [1] TRUE rs$run(function() 1+1) #> Error: interrupt rs$run(function() 1+1) #> [1] 2 It seems that the main loop somehow stores the SIGINT it

That doesn’t work too. :-( Last login: Mon Mar 19 19:18:16 on console iMac:~ andre$ mount /dev/disk0s2 on / (hfs, local, journaled) devfs on /dev (devfs, local, nobrowse) map -hosts on /net (autofs, nosuid, automounted, nobrowse) map auto_home on /home (autofs, automounted, nobrowse) /dev/disk2 on /Volumes/G-DRIVE Thunderbolt 3 (hfs, local, nodev, nosuid, journaled, noowners) iMac:~ andre$

OK, I managed to create an example without callr, but it is still somewhat cumbersome. Anyway, here it is. Terminal 1: mkfifo fif R --no-readline --slave --no-save --no-restore < fif Terminal 2: cat > fif Sys.getpid() This will make Terminal 1 print the pid of the R process, so we can send a SIGINT: Terminal 3: kill -INT pid The R process is of course still running happily. Terminal 2

Hi, I was wondering if anybody knew how to trap SIGINTs (ie Ctrl-C) in backend C++ code for R extensions? I'm writing a package that uses the GPU for some hefty matrix operations in a tightly coupled parallel algorithm implemented in CUDA. The problem is that once running, the C++ module cannot apparently be interrupted by a SIGINT, leaving the user sat waiting even if they realise

Unfortunately --interactive also makes the session interactive(), which is bad for me, as it is a background session. In general, I don't want the interactive behavior, but was wondering if I could send as SIGINT to try to interrupt the computation of the background process, and if that does not work, then I would send a SIGKILL and start up another process. It all works nicely, except for

I have a continuous loop running in an external library that I am calling from C (R API). This loop is processing events in real time with the possibility of significant lag between events. When processing an event, I can make use of R_CheckUserInterrupt, but while the external library code is waiting on a new event, I don't have an opportunity to call this - my entry points are only on

In preparation for the klibc 2.0.5 release I wrote a basic test script which: 1. Builds for each architecture (with a cross-compiler where needed) 2. Runs several statically-linked programs (using qemu-user where needed): a. Many self-test programs b. "sh -c exit" c. "sh -c '.../bin/true; exit'" The results for the architectures I was able to test are:

Hello everyone, I am searching and searching and can't find an answer. I try to register a sighandler in my extension's C code. But my sighandler is never called. Is there anything preventing extensions to receive signals? I register like this: [.. some code that works ..] // register the sigint listeners. if (signal(SIGTERM, killReceiver) == SIG_ERR) {

Hi Rsync Support, Recently we encountered issue on our prod environment because the rsync seems hanging, it took time building the list.Previously the rsync process was working before 10:24am not until 10:25am. See sample log below. We have one source server and the data files will be rsync to 2 webservers. Please advise what could be the cause of the issue. Please let me know if you need

A long-time missing feature (or bug, depending on how you look at it) is that a Ctrl-C at the password prompt in scp does not restore the terminal settings, thus dropping you to the command prompt without any keyboard echo. (A "reset" command will fix it.) This is a pretty regular occurance for me, and some others I've talked to - usually when you realize that the scp command you

I think for reliability and portability of termination, one needs to implement an application-specific termination protocol on both ends. Only within specific application constraints, one can also define what graceful termination means. Typically, one also has other expectations from the termination process - such that the processes will terminate in some finite time/soon. In some cases one

Hi, I am running Dovecot 2.2.26.0 compiled against OpenSSL 1.1 and, since upgrading to OpenSSL 1.1.0c, the "lmtp" process has been crashing with SIGSEGV whenever it receives SIGINT. This always happens a minute or so after the lmtp process handles a message. It can also be manually reproduced by sending SIGINT to one of the running lmtp processes. I am compiling and running on an

Hi, I''m wondering why SIGINT and SIGTERM both were chosen for the quick shutdown? I agree with SIGINT but not with SIGTERM. A lot of unix tools send SIGTERM as default (kill, runit among some) and it seems to be the standard way of telling a process to quit gracefully but not among Ruby people (there are a few other ruby processes behaving the same way). I just think it''s weird

I'm observing a difference in timing on nbdkit shutdown that is dependent on client behavior, and I wonder if that's a bug, but I can't figure out where to patch it. When there is no connection present, sending SIGINT to nbdkit terminates immediately. If, on the other hand, there is a single client currently connected, the termination behavior on SIGINT depends on what the client has

Hi, this is a type 3 bugreport ;) ( 3. Repeatable problems specific to your software layout.) first of all i must state, that i run openssh on a fairly old redhat based system (redhat 6.1). if you have any further questions, feel free to contact me. configure options: CFLAGS="-O2 -m486" ./configure --without-rsh --with-tcp-wrappers --prefix=/opt/openssh-2.3.0

In help("pskill", package = "tools") is says: Only SIGINT and SIGTERM will be defined on Windows, and pskill will always use the Windows system call TerminateProcess. As far as I understand it, TerminateProcess [1] terminates the process "quite abruptly". Specifically, it is not possible for the process to intercept the termination and gracefully shutdown. In R
