We have implemented a global fix for this issue in the following server
revisions:
- 6.0: rev 3339 [email protected]
- trunk: rev 3352 revision-id: [email protected]
This revision introduces two new config parameters and the corresponding server
startup parameters:
- osv_memory_count_limit: limit on number or records in each osv_memory virtual
table
- osv_memory_age_limit: limit on maximum age of records in each osv_memory
virtual table
The default values have been changed to count=False (disabled, it used
to be 200) and age=1.0 hour, so that with the default config the server
will only expire osv_memory records that are 1 hour old or more,
avoiding problems related with the use of osv_memory classes that
instantiate a large number of short-lived objects.
Server administrators are free to use the configuration parameters to tweak
these parameters globally if needed.
Module developers can also alter the self._max_count and self._max_hours values
in each osv_memory class directly (but should keep in mind that the server
admin expects the configured values to be applied!)
** Changed in: openobject-server
Status: In Progress => Fix Released

Title:
Number of ressources in osv.osv_memory object
Status in OpenERP Server:
Fix Released
Bug description:
On a wizard based on two osv.osv_memory objects with one2many
relationship, i canno't create more than 211 lines in the "many"
object.
I want to do a "pre" import of many csv lines into the osv.osv_memory
object before validating in the wizard and do the actual import in an
osv.osv object.
i made a simple scenario to check if it was a bug :
from osv import fields,osv
class test_school(osv.osv_memory):
def _do_import(self, cr, uid, ids, context={}):
myself=self.browse(cr, uid, ids, context)[0]
for i in range(0,myself.size):
self.pool.get("test.person").create(cr, uid, {
"name":"Doe",
"age":i,
"school_id":myself.id
})
return True
_name = "test.school"
_columns = {
"name":fields.char("name",size=20),
"size":fields.integer("size"),
"students":fields.one2many("test.person","school_id","students"),
}
test_school()
class test_person(osv.osv_memory):
_name = "test.person"
_columns = {
"name":fields.char("name",size=20),
"age":fields.integer("age"),
"school_id":fields.many2one("test.school","school",ondelete="cascade"),
}
test_person()
This is a silly example but you can make tests with size over 211 :
the number of lines will remains 211 (sometimes 201...) and only the
last added lines will remain in the table...
