Dear R-helpers, I've just started playing with getGraphicsEvent() in R, and was wondering if there is a simple way to stop this function waiting for input after a pre-defined time, instead of relying either on a non-NULL value from one of the event handlers or for a user-interrupt for it to halt (as per the R manual). The only way that I've thought of to make this work is using

Hello list, I have a strange problem with dovecot and quota. The error message is not obvious... After a couple of seconds when I try to start dovceot, I get this: root at taleira:~# /etc/init.d/dovecot start Alarm clock If I uncomment the "imap_quota and quota" in dovecot.conf everything seem to work fine: protocol imap { listen = *:143 ssl_listen = *:993 # problem pa

Not all FTP sites have the first release candidate, but it is at least available from ftp.freebsd.org. Please download and install this candidate and help us find bugs BEFORE we call it 4.9-RELEASE. ftp.FreeBSD.org/pub/FreeBSD/releases/i386/4.9-RC1 ftp.FreeBSD.org/pub/FreeBSD/releases/i386/ISO-IMAGES/4.9-RC1-i386-disc1.iso We are particularly interested in having people test this release

Well I definitely cannot use them as numeric because join is the main reason of those identifiers. About int64 and bit64 packages, it's not a solution, because I am releasing a dataset for external users. I cannot ask them to install a package in order to exploit them. I have to be very carefull when releasing the data. If a user just use read.csv functions, they by default cast the

Hello r users, I have to deal with int8 data with R. AFAIK R does only handle int4 with `as.integer` function [1]. I wonder: 1. what is the better approach to handle int8 ? `as.character` ? `as.numeric` ? 2. is there any plan to handle int8 in the future ? As you might know, int4 is to small to deal with earth population right now. Thanks for you ideas, int8 eg: human_id

Gidday everbody, We have just found an interesting issue regarding the sshd daemon on our SuSE system. For some reasons, the /usr/sbin/sshd process blocks SIGALRM as shown in the /proc/pid/status: $ cat /proc/`cat /var/run/sshd.init.pid`/status Name: sshd State: S (sleeping) SleepAVG: 0% [...] SigPnd: 0000000000000000 ShdPnd: 0000000000000000 SigBlk: 0000000000002000 <-- SIGALRM is

Hi I'm compiling: /usr/local/src/llvm/lib/Support/SlowOperationInformer.cpp on MinGW. However, it stops complaining about that SIGALRM is undeclared: -------------------------- @ /usr/local/build/llvm/mklib --tag=disable-shared --silent --tag=CXX --mode=compile g++ -c -I/usr/local/build/llvm/lib/Support -I/usr/local/src/llvm/lib/Support -I/usr/local/build/llvm/include

Ultimately, this is another function that needs to go into lib/System. An alternate approach is to fork a thread, sleep, and when the thread wakes up, "ring the alarm". Reid.

Hi there, I have a problem when I try to create a new user with swat. I use binaries of Samba 2.2.2 coming from www.samba.org, or from www.sunfreeware.com on Solaris 2.6 and on 8. I compiled the sources and the result is the same. When I click on "Add New User" (Server Password Management), I receive a nearly blank page: I can only see the samba gif on top and the user is not

Hi, I do have < INT_MAX. This looks attractive but since they are unique identifiers, storing them as factor will be likely to be counter-productive. (a string version + an int32 for each) I was looking to https://cran.r-project.org/web/packages/csvread/index.html This looks like a good feet for my needs. Any chances such an external package for int64 would be integrated in core ? Le 20

There's simply no equivalent to signals on Windows. There is no way to asynchronously interrupt a thread's processing to execute some handler. The only thing you can asynchronously do to a thread is kill it, and that's generally frowned upon (who knows what critical sections it might be holding, etc...). Stuff like alarms is supposed to be done using the "event-driven"

Hello, We've found some undesirable behavior with respect to LoginGraceTime. A minor code change in session.c seems to clear it up, but now I'm asking for help in better understanding the problem and determining if there any unexpected side effects of the change. First, the code change: $ diff orig_session.c session.c 216c216,218 < alarm(0); --- >

I have removed ANDIrand from my Solaris8 system and installed patch 112438-01 which provides native /dev/random and /dev/urandom devices. Recompiled both openssl-0.9.6c and openssh-3.1p1, restarted sshd. Now I seem unable to use scp, and connections to the local sshd appear to be very slow. $ scp php-4.2.0.tar.gz user at remote:/WWWserv/src local at bastion's password: php-4.2.0.tar.gz

This patch does two things. This test program results (on i386) in an error about _NSIG: #include <signal.h> #if defined (SIGRTMAX) int rtmax = SIGRTMAX; #endif The cause is that the kernel signal.h defines SIGRTMAX as _NSIG, then makes _NSIG invisibelby hiding it inside ifdef __KERNEL__. Perhaps it's more elegant to solve this in the kernel, but the ramifications of that scare

Murray, Your commits earlier this evening to zh_CN.GB18030 fixed that -STABLE breakage, but zh_CN.GBK appears still to be missing, which causes 'make installworld' to fail. Can you please fix this as well? install -m 644 -o root -g wheel uk_UA.KOI8-U.out /usr/share/locale/uk_UA.KOI8-U/LC_CTYPE install -m 644 -o root -g wheel zh_CN.eucCN.out /usr/share/locale/zh_CN.eucCN/LC_CTYPE

setTimeLimit(elapsed=1) causes a timeout error whenever a call takes more than one second. For instance, this is how it works on Windows (R 3.3.1): > setTimeLimit(elapsed=1) > Sys.sleep(10); message("done") Error in Sys.sleep(10) : reached elapsed time limit Also, the error propagates immediately and causes an interrupt after ~1 second; > system.time({ Sys.sleep(10);

Sure. ``` [global] workgroup = EXAMPLE server string = dns proxy = no interfaces = eth0 bind interfaces only = yes log file = /var/log/samba/log.%m max log size = 1000 # new options log level = 5 netbios name = FILES #panic action = /usr/share/samba/panic-action %d server role = STANDALONE SERVER local master = no security = user encrypt passwords =

Thank you for the feedback and confirmations. Interesting to see that it's also reproducible on macOS expect for Spencer; that might indicate a difference in builds. BTW, my original post suggested that timeout error was for sure detected while running Sys.sleep(10). However, it could of course also be that it is only detected after it finishes. For troubleshooting, the
