Subject: [Cocci] Checking import of code search results into a table by parallel SmPL data processing
Date: Sat, 20 Apr 2019 20:50:54 +0200	[thread overview]
Message-ID: <bed744fe-5c5c-cf28-f8b2-40a487709010@web.de> (raw)

Hello,

I have noticed another questionable software behaviour during the application
of the semantic patch language.

elfring@Sonne:~/Projekte/Linux/next-patched> time spatch --timeout 34 -j 2 --chunksize 1 -D database_URL=postgresql+psycopg2:///parallel_DVB_duplicates --dir drivers/media/dvb-frontends --sp-file ~/Projekte/Coccinelle/janitor/list_duplicate_statement_pairs_from_if_branches4.cocci > ~/Projekte/Bau/Linux/scripts/Coccinelle/duplicates1/next/20190418/pair-DVB-results.txt 2> ~/Projekte/Bau/Linux/scripts/Coccinelle/duplicates1/next/20190418/pair-DVB-errors.txt

real	5m56,708s
user	11m4,775s
sys	0m0,688s


I know from my previous update suggestion “[media] Use common error handling code
in 19 functions” that change possibilities can be found.
https://lkml.org/lkml/2018/3/9/823
https://lore.kernel.org/lkml/57ef3a56-2578-1d5f-1268-348b49b0c573@users.sourceforge.net/


But the generated log file contains the information “No result for this analysis!”.
I wonder then why desired data were not stored in the corresponding database table
by such a SmPL script variant.

Is there still a need to perform parallelisation for the mentioned software
components by other approaches?

Regards,
Markus
