[OpenSER-Users] RE: [Users] unixodbc: use_escape_common

by Papadopoulos Georgios

Hello Henning I just needed something quick and dirty so I just added the following function and used it instead of escape_common. This works fine with Oracle. int sql_escape(char *dst, char *src, int src_len) { int i, j; if(dst==0 || src==0 || src_len<=0) return 0; j = 0; for(i=0; i<src_len; i++) { switch(src[i]) { case '\'': dst[j++] = '\''; dst[j++] = src[i]; break; default: dst[j++] = src[i]; } } return j; } It would be nice to add this as a configuration parameter in the future. thanks George > -----Original Message----- > From: Henning Westerholt [mailto:henning.westerholt@1und1.de] > Sent: Thursday, June 21, 2007 12:00 PM > To: users(a)openser.org > Cc: Papadopoulos Georgios > Subject: Re: [Users] unixodbc: use_escape_common > > On Donnerstag, 7.

[Users] out of memory - please help

by Papadopoulos Georgios

Hello all, We have an ongoing issue with Openser running out of memory after a few hours. It is very consistent which makes me believe it is a memory leak. Can someone look at the log file? I have done a mem dump on process 8573 which is the one that ran out of memory. Here is the log: http://www.real.gr/files/openser.20070620.log.gz <http://www.real.gr/files/openser.20070620.log.gz> It always happens on the first receiver child. Our current solution is to restart Openser every few hours. I would like to solve this at its root, so please let me know if you need more info. My Openser is 1.2.x from svn, revision 2333. thank you for any help George Disclaimer The information in this e-mail and any attachments is confidential.

by Arun Kumar

Hi 1. Is there any benefit of increasing the value of PKG_MEM_POOL_SIZE and SHM_MEM_SIZE ? /*used only if PKG_MALLOC is defined*/ #define PKG_MEM_POOL_SIZE 1024*1024 /*used if SH_MEM is defined*/ #define SHM_MEM_SIZE 32 2. I've compiled my ser with #define PKG_MEM_POOL_SIZE 1024*1024*512 ans started using ser -m 100 option with children=4 and listening on two ips when I started memory usages was seems to fine for few days(3-4) less then 1GB but after that nealy 1.7 - 1.8 GB of memory usage and when I do top: 16165 root 15 0 617m 54m 36m S 0.3 2.7 0:16.34 ser 16167 root 15 0 617m 54m 36m S 0.3 2.7 0:15.89 ser 16164 root 15 0 617m 54m 36m S 0.3 2.7 0:16.29 ser 16166 root 15 0 617m 54m 36m S 0.7 2.7 0:16.16 ser 16172 root 16 0 617m 53m 35m S 0.0 2.7 0:05.04 ser 16168 root 16 0 617m 52m 34m S 0.0 2.6 0:00.09 ser 16170 root 16 0 617m 52m 34m S 0.0 2.6 0:00.07 ser 16169 root 16 0 617m 52m 34m S 0.0 2.6 0:00.08 ser 16171 root 16 0 617m 52m 34m S 0.0 2.6 0:00.10 ser 16163 root 16 0 617m 52m 34m S 0.0 2.6 0:00.01 ser 16145 root 25 0 617m 52m 34m S 0.0 2.6 0:07.80 ser it shows 11 instance of ser with above info. If I sum up 617 * 11 = 6787 MB of memory but in my machine I've only 2 GB Physical RAM and it never uses Swap ? if 54 * 11 = 594 ? but free -m and top shows more memory usage ? can please explain me in brief .

[Users] unixodbc: use_escape_common

by Papadopoulos Georgios

Hello all, I am using modparam("unixodbc", "use_escape_common", 1) and the result is that if I have a string like he'llo (single quote between the e and l), it becomes he\'llo which is not working in sql. The result should be he''llo (two single quotes between e and l). The reason is that unixodbc uses the core function escape_common(). I think that unixodbc whould have two parameters like modparam("unixodbc", "use_escape_character", "'") modparam("unixodbc", "escaped_characters", "'\%^") use_escape_character would be null by default and if it is not null it would be the character to use for escaping. escaped_characters would be a list of characters that should be escaped by the character defined above. I have patched unixodbc to use its own escape function instead, but it would be nice if this was a configurable option that others could use. I could try to implement this if there is an interest. Please let me know your thoughts. thank you George Disclaimer The information in this e-mail and any attachments is confidential.

[Users] Changing the prefix in subject for mailing lists

by Bogdan-Andrei Iancu

Hi, there were couple of requests to change the prefix used by the mailing list to something more descriptive. Like: [Devel] -> [OpenSER-Devel] [Users] -> [OpenSER-Users] I guess it is quite standard to have the project name included in the prefix, but I want to see if anybody is aware of an side effect ;) regards, bogdan
