BFD: BFD 2.13.90 20020903 assertion fail libbfd.c:1132 Can anyone help me explain this error? I see multiple of these when running an app in gdb. I'm using gcc 4.1.1, binutils 2.17, I suspect a build problem or a mismatch in e.g. binutils or something. /Per Jessen, Zürich

Read Write locks
by peter burden 10 Jul '06

10 Jul '06

Hello, Are there any problems with the pthread_rwlock routines ? I see some prototype warning messages on compilation but the programme seems to link OK and, as far as I can tell with a multi-threaded application, seems to work OK. Any recommendations for checking the various possible patterns of mutual interaction between threads in an MT application ?? Using gcc 4.1.1 and libc-2.3.5

False memleak detected?
by Verdi March 09 Jul '06

09 Jul '06

Hi, Valgrind detected memleak on one of my test case, which is a standard, textbook insertion sort. However, I don't see any problem with the testcase. I'm wondering if this is a false alarm, and should submit a bug report. I'm using SuSE 10.1, and valgrind-3.2.0-11.1 from opensuse build service. The followings are the test case and the output of valgrind. I've marked the offending line (line 36) in the testcase. /************************** Test Case ************************/ #include <stdio.h> #include <stdlib.h> typedef struct _int_struct { int i; struct _int_struct *next; } IntStruct; typedef struct _int_list { IntStruct *head; } IntList; int insert(IntList *ilist, int i); int insertion_sort(IntList *ilist, IntStruct *is); int main() { IntStruct *is; IntList ilist; ilist.head = NULL; insert(&ilist, 500); insert(&ilist, 100); printf("ilist: "); for (is = ilist.head; is; is = is->next) printf("%d ", is->i); printf("\n"); return 0; } int insert(IntList *ilist, int i) { IntStruct *is = (IntStruct *) calloc(1, sizeof(IntStruct)); /* line 36 */ is->i = i; return insertion_sort(ilist, is); } int insertion_sort(IntList *ilist, IntStruct *is) { IntStruct **isp; for (isp = &ilist->head; *isp; isp = &((*isp)->next)) { if (is->i < (*isp)->i) { is->next = *isp; break; } else if (is->i == (*isp)->i) { /* return FALSE; */ return 0; } } *isp = is; /* return TRUE; */ return 1; } /***********************************************************/ /************************ Valgrind Output ******************/ $ valgrind -q --leak-check=full ./a.out ilist: 100 500 ==15413== ==15413== 16 (8 direct, 8 indirect) bytes in 1 blocks are definitely lost in loss record 2 of 2 ==15413== at 0x40206D5: calloc (vg_replace_malloc.c:279) ==15413== by 0x80484CD: insert (coba.c:36) ==15413== by 0x8048461: main (coba.c:24) /***********************************************************/ -- Regards, Verdi -- Der GMX SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen!

Re: [suse-programming-e] problem with SLES 10

my expericence with QLogic Driver, is to use the lastest driver supplied from the manufacture for the version of linux that you are using. because mismatched Qlogic Driver would cause OS kernel panic. if QLogic Driver does have problem, you should able to see the messages in OS boot log or error log, Hunter <newtype(a)programmer.net> > ----- Original Message ----- > From: "MASTHAN DUDEKULA" <d.mastan(a)gmail.com> > To: suse-programming-e(a)suse.com > Subject: [suse-programming-e] problem with SLES 10 > Date: Mon, 3 Jul 2006 12:47:45 +0530 > > > Hi Folks, > > I am using SLES 10 latest beta bits.

Beginer Java tips, for a profesional
by Jerry Westrick 05 Jul '06

05 Jul '06

Hello to all... I'm starting a small project in JAVA, just to gather a little experience with it. The project I picked is a FIX (http://www.fixprotocol.org) message viewer. It's comething that I think can be used, and a topic I have lots of experience with, so that I can consentrate on the JAVA. I'm using SUSE 10.1 as development platform. I have extensive experience in programming (COBOL, PL/I, 360 Assembler, C/C++, Smalltalk, Prolog, Perl, Python, just mention a few) and feel it's time I did a little JAVA. So anyone have tips, and gotchas I should watch out for? Suggestions for how to get into a workbench with little effort? Thx. for your help Jerry

Hi Folks, I am using SLES 10 latest beta bits. I think there was a problem in QLogic driver in SLES 10 beta bits. I have a VA (Virtual Array), it has 4 LUNs, /dev/sda, /dev/sdb, /dev/sdc, /dev/sdd. To reset scsi device i isssued the following command #sg_reset -d /dev/sg1. After issueing this command, the machine is not coming up ( it is hanging) Later i wrote the following script for resetting device,. but still i have the same problem int main(int argc, char * argv[]) { int fd; int rc; int arg=2; if ((fd=open("/dev/sg3", O_RDWR)) < 0) { printf( "device open fails"); return -1; } if ((rc=ioctl(fd,SG_SCSI_RESET,&arg)) < 0 ){ printf( " ioctl failed "); close (fd); return -1; } printf ( " reset success "); close (fd); return 0; } After running the above script, the status of the machine is something like this 4>[ACPI Debug] String: [0x0B] "_TMP Method" :<6>qla2300 0000:06:01.0: scsi(0:0:2:0): LOOP RESET ISSUED. :<0>BUG: spinlock already unlocked on CPU#0, diskres/5242 :<0> lock: dfbd4034, .magic: dead4ead, .owner: <none>/-1, .owner_cpu: -1 :<4> [<c01058fa>] show_trace+0xd/0xf :<4> [<c0105a1d>] dump_stack+0x17/0x19 :<4> [<c01ce308>] spin_bug+0x7e/0xc0 <4> [<c01ce376>] _raw_spin_unlock+0x2c/0x70 :<4> [<c02c5878>] _spin_unlock_irq+0x8/0xb :<4> [<f933613c>] qla2xxx_eh_bus_reset+0xae/0x1cc [qla2xxx] :<4> [<f90290b8>] scsi_try_bus_reset+0x41/0x9a [scsi_mod] :<4> [<f90297fe>] scsi_reset_provider+0x111/0x19e [scsi_mod] :<4> [<f90c282d>] sg_ioctl+0x8e5/0x9ca [sg] <4> [<c0172f77>] do_ioctl+0x4f/0x68 :<4> [<c01731ea>] vfs_ioctl+0x25a/0x26d :<4> [<c0173244>] sys_ioctl+0x47/0x63 :<4> [<c0103e39>] syscall_call+0x7/0xb :<6>qla2300 0000:06:01.0: qla2xxx_eh_bus_reset: reset succeded \ Your help is appreciated.
