I realize your advice - no effect!
I analyzed *session.connect* and found strange place at the biginig of
*connect *definition:
...
self._unlock(response) # - *unconditional unlock *session file witch
have a name == response.session_id
...
Then I changed definition of ajx_bug(): form=SQLFORM.factory(Field('any',
*comment=response.session_id* ), table_name=form_name)
and here is I got:
Many Ajx Form
ajx_frm_0:
Any
127.0.0.1-dd2c6b6c-3141-4826-8887-ab1691b67350
ajx_frm_1:
Any
127.0.0.1-dd2c6b6c-3141-4826-8887-ab1691b67350
ajx_frm_2:
Any
127.0.0.1-dd2c6b6c-3141-4826-8887-ab1691b67350
All ajax responses have the same response_id! i.e. each ajax-process can
unlock session file locked by another!
In other words, requests parallel processing works properly across
sessions, but not within one session, because all responses within session
have the same response_id
It seems, that file is not locked across parallel process (on my Win7 at
least), may because it is children of one parent or something else?
