[PHP-DB] PHP / iODBC / PostGreSQL: running into a deadlock
Hi, I recently decided to setup my mac for some php developments. OS X 10.5 already ships with Apache, PHP and I chose PostGreSQL as DB server. I picked a package link from the official website and I installed it. The DB server is running smoothly. Now, as OS X's php module is not pgsql-enabled, I chose to take advantage of libiodbc (which php can handle). I installed psqlODBC driver. - testing with `iodbctest': the program finds libiodbc which in turns uses psqlODBC driver to connect to the database; I can issue SQL statements which succeed = OK - connecting php to libiodbc (note that I get the same results whether I use php module with Apache or the CLI): odbc_connect() works correctly, the DSN is found and I get a connection on PostgreSQL server. The problem arises when I try to use odbc_prepare(), odbc_exec(), etc. functions. I run into some kind of a deadlock which causes those functions to never end. I couldn't find any solution/description of this problem for Mac platform in Google. To try to solve this issue, I grabed the sources for PHP (5.3.2) and libiodbc (3.52.7). When ran under GDB, I can observe the following: odbc_exec() [PHP code] calls SQLAllocStmt() [libiodbc code], which calls some internal function that tries to call SQLAllocStmt(), in some indirect recursive way. As SQLAllocStmt() is protected by a mutex, there's a deadlock. The BT is as follows: #0 0x90529d85 in pthread_mutex_lock () #1 0x00bd6cec in SQLAllocStmt (hdbc=0x1016200, phstmt=0x1828034) at hstmt.c:427 #2 0x00bd667a in SQLAllocStmt_Internal (hdbc=0x1827940, phstmt=0xdc5cec) at hstmt.c:241 #3 0x00bd6db6 in SQLAllocStmt (hdbc=0x1827940, phstmt=0xdc5cec) at hstmt.c:430 #4 0x00238808 in zif_odbc_exec (ht=2, return_value=0xdc454c, return_value_ptr=0x0, this_ptr=0x0, return_value_used=0) at /usr/local/php/src/5.3.2/ext/odbc/php_odbc.c:1551 #5 0x004d020d in zend_do_fcall_common_helper_SPEC (execute_data=0xf28040) at zend_vm_execute.h:313 #6 0x004d5815 in ZEND_DO_FCALL_SPEC_CONST_HANDLER (execute_data=0xf28040) at zend_vm_execute.h:1603 #7 0x004cf346 in execute (op_array=0xdc5d38) at zend_vm_execute.h:104 #8 0x0049fec9 in zend_execute_scripts (type=8, retval=0x0, file_count=3) at /usr/local/php/src/5.3.2/Zend/zend.c:1194 #9 0x004231f5 in php_execute_script (primary_file=0xb98c) at /usr/local/php/src/5.3.2/main/main.c:2260 #10 0x00578f7b in main (argc=2, argv=0xba84) at /usr/local/php/src/5.3.2/sapi/cli/php_cli.c:1192 Regarding why this doesn't occur with `iodbctest', the answer is that is simply doesn't call SQLAllocStmt(). It replaces this call with SQLAllocHandle(). Now, I'm wondering: - am I the only nut to try such setup on OS X (Apache, PHP, ODBC, Postgres)? - is that some configuration issue? - is that a problem either in PHP or libiodbc code?

[PHP-DB] PHP and PostgreSQL
I am new to PHP. Trying to install it and PostgreSQL 8.0 on Slackware Linux 10.0.0 . I am getting the following error out of Apache: Fatal Error: Call to undefined function: pg_connect() After browsing your web site, I found http://us2.php.net/pgsql . But am unable to proceed because I am not sure what to do. Specific questions: (1) How do I determine what version of PHP I have? Browsed PHP directories, but couldn't find it. (2) The information I found said I could use a shared object module and/or (I think) alter php.ini . I don't think this is hard to fix, but I need to find a blow-by-blow of what to do. Can somebody help me?
Re: [PHP-DB] PHP and PostgreSQL
Did you compile php or did you install from a binary? If you compiled -- did you configure the PHP module --with-pgsql? I have not installed a binary in the past so I am not sure how you activate the pgsql module in that regard. The problem though is that the version of PHP you are running is not configured to support pgsql and you will need to do that to get it recognize the pgsql specific functions. ?php /* Stephen Johnson c | eh The Lone Coder http://www.thelonecoder.com [EMAIL PROTECTED] 562.924.4454 (office) 562.924.4075 (fax) continuing the struggle against bad code */ ?

RE: [PHP-DB] PHP and PostgreSQL
save this to a php file and run it. I a attached file just in case. ?php phpinfo(); ?

RE: [PHP-DB] PHP and PostgreSQL
I think from binary; it was installed as a part of Slackware, and I made no special efforts to compile. Version of PHP is 4.3.7 (thanks Mychael) Other: Linux kernel is 2.4.26 Apache version is 1.3.31 Looks like MySQL may already be configured in PHP (saw that in phpinfo() ) When installing PostgreSQL, I am fairly certain I made no attempt to configure anything in the database to permit use of PHP, as that was not a consideration at that time. In fact, not sure it even asked; it did ask about some languages (stored procedure language, TCL, etc). -Original Message- From: Mychael Scribner [mailto:[EMAIL PROTECTED] Sent: Thu 3/10/2005 2:40 PM To: Van Ingen, Lane; php-db@lists.php.net Cc: Subject: RE: [PHP-DB] PHP and PostgreSQL save this to a php file and run it.

[PHP-DB] PHP and PostgreSQL: Cannot create new link. Too many open links (0)
Hi All! After working with PHP and MySQL and Firebird quite a while I need to install PostgreSQL. After installation I made a new build of PHP to support PostgreSQL. I looked over the ini files and re-started Apache. With psql I can connect like: psql -h localhost But not any chancen seen with PHP. I even just made a small script with just two echo lines and a pg_pconnect() / pg_connect(). This is the error Message I get: Warning: pg_pconnect(): Cannot create new link. Too many open links (0). in /www/test.php on line 5. I get this message no matter what connection string I use. Even if I leave it totally blank or put some nonsense in, I get the same error. Any hint appreciate - Thanks in advance!

[PHP-DB] PHP, Apache PostgreSQL
When I execute a pg_connect() in a .php file, I get an error indicating that the function is not defined... That's because, in the Apache error log I'm getting the following: PHP Warning: Unable to load dynamic library '/usr/lib/pgsql.so' - libpq.so.2.0: cannot open shared object file: No such file or directory in Unknown on line 0 I have confirmed that my pgsql.so and libpq.so.* files are in my directory specified in the php.ini file. And that the exention for pgsql.so exists in the php.ini also. Would anyone know what I missed here?
