This version has been committed to CVS with one minor change: I made the warning about caller calling LeaveCriticalSection a little more prominent.

Objects in PHP4
I've been looking at the PHP4 bindings, wondering why we don't have "proper" objects. Digging back through mail and CVS logs, it looks like I updated the SWIG invocation for PHP from using "-shadow" to using "-noproxy" so that it worked with newer versions of SWIG. But that's wrong as the switches have opposite meanings (and what was "-shadow"

ustack()s of SIGSEGV''ed programs
Hi all, I am trying to write a D script which would print ustack() for every program in the system receiving SIGSEGV. All the stacks printed in trap()/sigtoproc() context do not have meaningful symbols. The following solves the problem to some degree but I''d much rather have a self-contained D script. dtrace -w -n ''fbt:genunix:sigtoproc:entry/arg2 == 11/ {

Extending lwpsinfo_t with pr_lgrp for DTrace consumers
The sched provider defines the stable "lgrp" variable that is the lgroup of the current CPU. This is mostly interesting when we can compare it with the actual thread home lgroup, so I''d like to extend the lwpsinfo_t structure with the new pr_lgrp field which will be implemented using translator. This will match the addition of the pr_lgrp field to the proc(4) lwpsinfo_t

sched provider
Hi All, I used the following script from the dtrace manual to measure how long a particular process runs on the cpu. Modified it to look at the exact timestamps: [i] sched:::on-cpu { self->ts = timestamp; printf("on=%d\n", self->ts) } sched:::off-cpu /self->ts/ { printf("off=%d\n", timestamp) self->ts = 0; } [/i] The output looks like this: [i]on=24591 off=24603

Surprise Thread Preemptions
Hi, I would like to know about which threads will be preempted by which on my OpenSolaris machine. Therefore, I ran a multithreaded program "myprogram" with 32 threads on my 24-core Solaris machine. I make sure that each thread of my program has same priority (priority zero), so that we can reduce priority inversions (saving preemptions -- system overhead). However, I ran the following

beginner question - effective way to chart sleep habits
Hi - beginning R user question here - each day, over the course of several months, I've tracked the time I go to bed, the time I wake up, and my hours spent sleeping. What would be a good way to display this information? I think it would be ideal to show something resembling a bar and whisker graph for each day that would show the interval of hours spent asleep (or perhaps just a bar

POSIX semaphores in CentOS 5.1?
According to the man pages for sem_wait, etc., POSIX semaphores are available in Linux 2.6 (with the right NTPL threading in glibc). However, I have a program that compiles just fine but won't link because it can't find the library for the semaphore operations. What am I missing? I ran a find and grep through all the libc's on the system and they turned up nothing: $ find /lib

iostat -xn 5 _donot_ update: how to use DTrace
on Solaris 10 5.10 Generic_118822-23 sun4v sparc SUNW,Sun-Fire-T200 I run #iostat -xn 5 to monitor the IO statistics on SF T2000 server. The system also have a heavy IO load, for some reason iostat donot refresh (no any update). It seems like iostat is calling pause() and stucked there. Also my HBA driver''s interrupt stack trace indicates there is a lot of swtch(), the overall IOPS

Using dtrace to follow a kernel linked list
I''m looking for an example of how one could write a dtrace probe that could follow something like a NULL terminated linked list. For example: struct list { struct list *next; void *data; }; struct list *list_root; Assuming I had "list_root" available, but I wanted to know how long the linked list is, how can I do this in a dtrace probe? If I had looping
