[Cppcheck 2.18.0] serious regression (--cppcheck-build-dir)

[Dave Ohlsson]

Cppcheck has a very useful option: --cppcheck-build-dir. According to --help, one advantage of this option is:

faster analysis; Cppcheck will reuse the results if
the hash for a file is unchanged.

And indeed, when we run Cppcheck 2.14.2 on our whole project with --cppcheck-build-dir, the first time takes about 14 minutes, but if we run Cppcheck again with --cppcheck-build-dir without making any changes to the code to be analyzed, it now takes only about 1 minute.

With Cppcheck 2.18.0, however, we do not observe any speed-up. Running Cppcheck on our whole project with --cppcheck-build-dir takes about 15 minutes the first time, and also the second time.

I didn't try with versions between 2.14.2 and 2.18.0.

Is this a known regression?

Thanks for reporting, ticket is here: https://trac.cppcheck.net/ticket/14064

I noticed from https://trac.cppcheck.net/ticket/14064 that this is now fixed. Thank you!

Do you know when the next version (which I presume will include this fix) will be available?

Urgh I've spent a few hours today assuming it was something local that had caused this...

Please can we get a 2.19 ASAP?

Ours went from a few seconds to 8 minutes each time we run the tool so I've had to rollback
