Is there a pragma to turn off padding or some other mechanism besides dummying up fields to make them char[] to disable padding? Thanks!

Howdy, I am attempting to isolate the location of a memory leak in a 4GL program, and have hit a bit of a snag. When I LD_PRELOAD libumem and run the application server, "::findleaks -fdv" reports numerous leaks: CACHE LEAKED BUFCTL CALLER 0000000100b49068 15 0000000100ef2d50 fdcon+0x6c4 0000000100b50028 1 0000000100b72ac0 fdcon+0x6c4 0000000100b49068

After building and bfu''in the lastest ON build, any time I run a dtrace script I get a Seg Fault.

Hi, I have mentioned before that we have added some sdt dtrace probes in SAX, our APL interpreter. Encouraged by Angelo and Jignesh, I have created a small document (5 pages) describing our experience with it, together with some problems we have encountered and some scripts we use for pretty-printing dtrace outputs. The said document can be found at

Howdy, I installed Nevada build 49 in a parallels VM on my intel mac mini, and when I run the following DTrace script: $ cat follow.d #pragma option D flowindent; pid$target:::entry, pid$target:::return {} $ cat format.cmds disk 0 exit $ dtrace -s follow.d -o follow.out -c "/usr/sbin/format -f format.cmds" dtrace: script ''follow.d'' matched 13641 probes The system

/usr/sfw/bin/firefox is a shell script which calls run-mozilla.sh which calls firebox-bin. Is there a way to call dapptrace on firefox in order to trace firefox-bin? This message posted from opensolaris.org

[1] Predicates in one-liners I would like to list the probe modules in my executable and then dynamically create a dscript to trace execution of those modules alone (by excluding the 3rd party and system libraries). I tried the below script without success. The conditional given in the predicate is not taking effect. Why is this so ? $ dtrace -ln ''pid$target:::

There is a Slashdot discussion today titled "Cambridge Researcher Breaks OpenBSD Systrace". Slashdot anonymous member has a comment "Even Sun''s Dtrace might be vulnerable." I don''t think it is.

hi, I''m using the PID provider to trace a 32-bit app, prtdiag. I''m trying to print the value of "propname" (arg1) in the following func: int picl_get_propval_by_name(picl_nodehdl_t nodeh, const char *propname, void *valbuf, size_t nbytes) ... i''ve tried many versions, but this is a representative one: 53 this string propname; 54 55

A small script to see what SCSI commands are being issued by a system: http://blogs.sun.com/roller/page/chrisg?entry=scsi_d_script Still work in progress as I needs to handle larger CDBs but it is a start, since I don''t have a disk that big it is not a problem for me yet. Also getting the return scsi packet is a hack but so far I can see no alternative short of knowing about all the

------------------forwarded------------------------------------ This is to help my customer to migrate their IBM websphere 6.0.2 to run on solaris 10 platform. Customer is eager to use the dtrace agent of JDK (https://solaris10-dtrace-vm-agents.dev.java.net/ ) to benefit their IBM websphere server, I am not sure whether we can use this agent in IBM websphere bundled JDK whose version is JDK

I''m pleased to pass along news that the Mac OS X DTrace port has been updated in 10.5.3 to fix the issue that caused timer based probes not to fire in the presence of certain untraceable applications. http://blogs.sun.com/ahl/entry/apple_updates_dtrace A big thank you to the folks at Apple for addressing the problem.

G''Day Folks, I''ve found another use of dtrace, this makes your console keyboard sound like a typewriter. http://www.brendangregg.com/DTrace/typewriter-0.70.tar.gz I''ve only tested it on an UltraSPARC 5 and a Pentium laptop so far, more to follow. Ok, sorry, not actually a practical use of DTrace. :) Enjoy! Brendan [Sydney, Australia]

everyone, Just out of curiosity, I did a dtrace -n ''syscall:::entry { @num[execname, probefunc] = count(); }'' and looked at the entries produced by ''rm''. I see everything that rm did, *except* the unlinkat - which is unfortunate because I want to trace which processes have deleted which files. So - does dtrace contain unlinkat as a probe for a system call?

Hi Expert I want to use dtrace to monitor the content change of one file. I made following scripts, #!/usr/sbin/dtrace -s inline int MYPID = $1; syscall::write:entry /pid == MYPID/ { tracemem(arg1, arg2); printf("\n"); } It always has an following error bash-3.00$ sudo dumpFIFO.dtrace 3836 dtrace: failed to compile script ./dumpFIFO.dtrace: line 19: tracemem( ) argument #2

Howdy, Is there a method to get the number of elements in an aggregation? Are the results stored in an aggregation guaranteed to be in any type of order? Thanks for any insight, - Ryan -- UNIX Administrator http://daemons.net/~matty

I would like to know how to get access to errno when using pid provider to probe calls to libc functions like fopen(). The built-in errno appears to be only for system calls. What I''d like to be able to do is investigate where in an application I''m encountering EMFILE and what the stack looks like at the time. This message posted from opensolaris.org
