Re: [Symbolic-users] FW: Operation Running

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

1° database export

For the database export, this is what i thought.

But I can't see the definition for the symbolic operation I created:

grep augeas /var/lib/symbolic/db/*

/var/lib/symbolic/db/symbolicDb.log:INSERT INTO OPERATION_LOG VALUES(5,1,'2008-10-29 16:02:31.501000000',NULL,2,5,'nladev03.neptune.dkcorp.net-changeconf_augeas-chgParam-1225292553.724438',FALSE,NULL,NULL,1,2,'')
/var/lib/symbolic/db/symbolicDb.log:INSERT INTO OPERATION_LOG VALUES(6,1,'2008-10-29 17:50:12.182000000',NULL,2,5,'nladev03.neptune.dkcorp.net-changeconf_augeas-chgParam-1225299014.0967519',FALSE,NULL,NULL,1,2,'')
/var/lib/symbolic/db/symbolicDb.log:INSERT INTO OPERATION_LOG VALUES(5,2,'2008-10-29 16:02:31.501000000','Func Async Process Lost!',2,5,'nladev03.neptune.dkcorp.net-changeconf_augeas-chgParam-1225292553.724438',FALSE,'WARN: Func Server was probably restart after command ran on client.',NULL,3,2,'')
/var/lib/symbolic/db/symbolicDb.log:INSERT INTO OPERATION_LOG VALUES(8,1,'2008-10-29 17:53:54.177000000',NULL,2,5,'nladev03.neptune.dkcorp.net-changeconf_augeas-chgParam-1225299238.6513391',FALSE,NULL,NULL,1,2,'')
/var/lib/symbolic/db/symbolicDb.script:INSERT INTO MODULE VALUES(3,0,'changeconf_augeas','Default Description','','chgParam,module_description,module_version,get_method_args,module_api_version,list_methods','changeconf_augeas')

Where are Operations stored ?

2° my module

Here is the module (POC version, I'm still working on it):
#changeconf_augeas.py

try:
    from func_module import FuncModule
except:
    class FuncModule:
        pass

class chgConf(FuncModule):
    version = "0.0.1"
    api_version = "0.0.1"
    description = "Change parameters in plain text configuration files, with the help of Augeas."

    def chgParam(self,fileName,param,pvalue):
        """Change a value for a config. parameter in a plain text config. file
with the help of Augeas, a configuration API (cf http://augeas.net) 
"""
        try:
            from augeas import augeas
            aug=augeas()
        except Exception, e: return str(e)

        path='/files/'+fileName

        try:
            getTest=aug.get(path+"/"+param)
        except Exception, e: return str(e)

        if not getTest:
            message="""Failed. Possible reasons:
- the config file does not exist
- the config parameter does not exist in the config file
- Augeas does not handle the configuration format as expected"""
            return message

        try:
            aug.set(path+"/"+param,pvalue)
        except Exception, e: return str(e)
        try:
            aug.save()
        except Exception, e: return str(e)

        try:
            getTest=aug.get(path+"/"+param)
        except Exception, e: return str(e)

        return [fileName,param,getTest]

In parallel I will make some new check with a very simple test module using methods with more than 1 parameter.

Yes we have tested with more than one parameter... but maybe there is a
specific problem calling that one. We are making a call using
"func-trasmit" (so not CLI) and all "instructions" are passed through a
yaml/json serialization.

Can I have your module code to make some specific test... so I can see
what are working wrong in that situation?

To "export" the hsqldb you just need to copy the db files you can find
in symbolic folder (if I remember well /var/lib/symbolic/db).
