Subject: [Cocci] Checking execution environment for Python code in SmPL scripts
Date: Sat, 20 Apr 2019 09:30:11 +0200
Message-ID: <> (raw)

I constructed a SmPL script which can work as desired.

elfring@Sonne:~/Projekte/Linux/next-patched> spatch drivers/media/dvb-frontends/tda1004x.c ~/Projekte/Coccinelle/janitor/list_duplicate_statement_pairs_from_if_branches3.cocci
Using SQLAlchemy version:
statement1|statement2|"function name"|"source file"|incidence
kfree ( state ) ;|return NULL ;|tda10045_attach|drivers/media/dvb-frontends/tda1004x.c|2
kfree ( state ) ;|return NULL ;|tda10046_attach|drivers/media/dvb-frontends/tda1004x.c|2

Unfortunately, I get another unexpected test result by the following command.

elfring@Sonne:~/Projekte/Linux/next-patched> spatch -D URL=postgresql+psycopg2:///media_duplicates1 drivers/media/dvb-frontends/tda1004x.c ~/Projekte/Coccinelle/janitor/list_duplicate_statement_pairs_from_if_branches4.cocci
Traceback (most recent call last):
  File "<string>", line 4, in <module>
NameError: name 'store_statements' is not defined
exn while in timeout_function

The following display shows intended differences between these SmPL scripts.

+URL << virtual.database_URL;
 import sqlalchemy, sys
-engine = create_engine("sqlite:///:memory:", echo=False)
+if URL == False or URL == "default":
+   URL = "sqlite:///result-duplicates.db"
+engine = create_engine(URL, echo = False)

The custom function “store_statements” should be usable in both script variants.
Now I wonder about the shown software behaviour again. How can it be fixed?
