Memory allocation error: pdo-odbc

[ALPBRCH]

Hello,

Since php version 8.1, the following error occurs when writing to the DB: Fehler SQL: SQLSTATE[HY001]: Memory allocation error: [IBM][System i Access ODBC-Treiber]Speicherzuordnungsfehler. (SQLPrepare[0] at /builddir/build/BUILD/php-8.2.21/ext/pdo_odbc/odbc_driver.c:200).

Situation: Linux-Oracle-Server: PHP 8.3.9 (x86_64) IBM iSeries: ibm-iaccess-1.1.0.28-1.0.x86_64

No problems with php-8.0!

Best regards Jürgen Immel

This is the repository of the German translation – I'm transferring to php-src.

The mentioned line would be

https://github.com/php/php-src/blob/482ca6c19c4d776c37bcdd5823edd524f4199cfa/ext/pdo_odbc/odbc_driver.c#L200-L200

Maybe @NattyNarwhal has an idea what might be wrong there. Other than that, we probably need a small self-contained reproduce script, and perhaps an ODBC trace would also be helpful.

test_odbc.txt This is a simple example of a script. Out of 10 inserts, 3 work.

Do you have the CREATE TABLE definition?

Hi, some additional information: Linux Server-> unixODBC.x86_64 2.3.7-1.el8

IBM Power 9 Release V7R3M0

I'll take a look at this this week; I was on vacation last week.

I'm confused because I look at that CREATE TABLE definition and it's for MySQL, but the driver issue is for Db2i.

[ALPBRCH]

Hi, Sorry, you're right. The create is from Mysql. The DB2 database was created with a DDL description which unfortunately I cannot provide.

Hello, I asked the developer to give me a create or DDL of the tables.

best regards-Jürgen

[ALPBRCH]

bestpos.txt bestkopf.txt Hi, here the DDL of the tables. Regards

[ALPBRCH]

Any news?

[NattyNarwhal]

Sorry about this, I got busy with other projects. I'll take a look this week.

[NattyNarwhal]

That DDS is missing the record format. Can you provide the full PF source, including record formats, or the SQL DDL?

[ALPBRCH]

BESTPOSDD.txt BESTKOPF_DD.txt The record format is in the DDS. The line with “R” stands for record. says the developer

[NattyNarwhal]

I think BESTKOPF is missing the first line that indicates what file it references (the one with REF IIRC); there's the R in position 17 for the record format, and the subsequent lines in position 29 for fields.

There was some SEU issues in the copy and paste, but after manually cleaning it up, I've managed to create the tables on my system. I haven't been able to reproduce the issue on my systems yet (server with i 7.2, client with PHP 8.3.10 on macOS 14). I'll try to test on Linux soon.

[ALPBRCH]

Sorry, unfortunately I had no other option to pass on the data. I also suspect it is problem with php on Linux OS
