Installation problem on Trac 0.11 and PosgreSQL

[Roberto Longobardi]

Reporting a mail thread here as a ticket, for reference to other users.

================================================= Hi Roberto!

I'm sorry to bother you this way directly, but I didn't found anything useful from google to my problem. I would appreciate if you could help me a little.

I'm trying to install TestManager 1.4.4 to Trac 0.11.7. I did the installation from source by easy_install. The installation went ok (I think). When I try to enable the plugins, trac tell to execute upgrade. But when executing the upgrade to trac it gives me a error:

"psycopg2.ProgrammingError: type "int64" does not exist LINE4: "time" int64,"

I have updated python-psycopg2 package to version 2.4-1.1 but it didn't help. What is the component which is missing the type int64 or what might be the problem?

The system in running on SUSE Linux Enterprise Server 11 (x86_64) version 11, patch 1. Postgresql-server v8.3.9-0.1.1.

Br, Timo

Here are whole error which comes when running the upgrade command:

psycopg2.ProgrammingError: type "int64" does not exist LINE 4: "time" int64,

If the python is correct version, is there any other component that could not understand the int64 type?

Hi Timo, I found your problem. It is Trac's PosgreSQL support which does not convert the int64 column type to bigint.

This mapping was added in Trac 0.12, while I see you're using 0.11.7.

Is it a problem for you to upgrade to 0.12 (I suggest 0.12.2)?

Let me know. Ciao, Roberto

[Erik Andersson]

I ran into this now as well. Not really able to upgrade atm.

Any workaround?

[Roberto Longobardi]

Hi Erik, I've developed a piece of code that during plugin installation detects whether Trac has support for timestamps in seconds (which just require an "int" data type, and which is the situation on Trac 0.11) or microseconds (which instead require "int64", on Trac 0.12) and creates the database tables accordingly.

If you wish to try it, I'm attaching the three modified files to this ticket.

Unzip the attached archive and replace the corresponding files in the source tree. tracgenericclass/trunk/tracgenericclass/model.py testman4trac/trunk/testmanager/model.py tracgenericclass/trunk/tracgenericclass/util.py

Please, let me know if it works on MySQL and Trac 0.11 (I don't have such an environment) so that I can put the fix into the main release.

[Erik Andersson]

Hi

I'll try tomorrow!

One question though, why are you talking about MySQL? I am too using PostgreSQL. Just a typo?

[Erik Andersson]

Upgrade worked fine with the patch! So consider this one fixed.

Since I'm on python 2.4 I encountered another issue though when running Trac.. I'll see what I can do about that.

Thanks for your help.
