The project goal is to incorporate the functionality of interaction of the excel application (gnumeric) with the XO's journal. All the activities needs to register any change in that datastore (save and open files are made throw it).

In order to apply this option, we need to call some python code from the implementation of the worksheet in C code. This is called embedded python in C. The steps followed to accomplish this goal came from the OLPC site recomendations, in wiki.laptop.org. The python script for the interaction with the journal's datastore can be found in here: http://wiki.laptop.org/go/Copy_to_and_from_the_Journal

The changes in the gnumeric code are basically in the workbook-view.c and main-application.c to handle the open and save options. In the main- application.c the method gui_file_copy_from_journal uses the python api/c to make the call to the journal script. after this method and during the open of the file, an exception rises. Although we are not sure, we believe it has to do with the closure of the python enviroment after the finalize call. We need to erase this exception or may be just handle it.

The error running in the XO is:

gnumeric: Python/pystate.c:561 :PyGILState: The assertion 'autoInterpreterState' has failed

The configuration of the XO where we are getting the exception is:

Python 2.5 (r25:51908, Oct 19 2007, 09:47:40) [gcc 4.1.2 20070925 (Red Hat 4.1.2-27)] on linux2

Any help is greatly appreciated!!!

Is this an actual bug report or more of a request for help? If it is the former then a test case is needed in order to help figure out what is going on. If it is the latter you should ask on comp.lang.python/python-list.

Also, please do not add everyone in the project to the nosy list.

The assertion is clear if you open the source code (Python/pystate.c, line 561):

assert(autoInterpreterState); / Py_Initialize() hasn't been called! \/

Does your code make sure that the python interpreter is initialized?

Hi Amaury, thanks for you response...

This is my code sniped

gboolean gui_file_copy_to_journal(char const *uri) { g_printerr("SAVING PYTHON JOURNAL!...........%s\n", uri);

        char * arg1[7];

    arg1[0] = "python";
    arg1[1] = "/home/olpc/copy-to-Journal.py"; 
    arg1[2] = uri+7;
    arg1[3] = "-d";
    arg1[4] = "hoja_de_calculo"; 
    arg1[5] = "-m";
    arg1[6] = "application/x-gnumeric";

        g_printerr ("Writing py \n");
        Py_Initialize(); 
        Py_Main(7, arg1);
        Py_Finalize();
        g_printerr ("Writing Py_Finalize \n");

        return TRUE;
}

also, I tried with other method like linux journal show in http://www.linuxjournal.com/article/3641

Any help is greatly appreciated...

Py_Initialize(); Py_Main(7, arg1); Py_Finalize();

This seems correct... unless two threads run this function at the same time. Can you ensure that this is not the case?

It seems to me that a simple call to system("python /home/olpc/copy-to-Journal.py [other-args-here]") would be better...

1d0cf1aa-0356-403c-aec2-b356dd36a537 commented 15 years ago

Thank you so much. It do worked!

I don't think two threads to be running the same function because the messages are displayed only once. Yes it seems to be a better way it worked, thank you again.
