Alerts in LGTM, No alerts in CodeQL-Action

[Jee-Bee]

I'm not sure if this is the right repository (If not point me to the right one).

Currently i use lgtm for code analysis, but since it will stop working i want to try moving to CodeQL.
As of now i have added it to two of my repositories, but at the same time i'm not sure if it works well.
I use for both (lgtm and the CodeQL action) the default setup. In lgtm i have some alerts while in CodeQL i don't have any.
for pointing to the right repositories:

• Mopho - 4 Alerts
• FreePDM - Main branch only - Currently 6 Alerts

Both repositories are written in python.

I am currently running in circles through the documentation but i can't find anything that lead me to where the difference come from. I have no idea how to set CodeQL that the results are equal... Is there any documentation what different settings are between lgtm and code QL.

Thanks in advance

By default the codeql-action runs only security-related queries, while LGTM runs a lot more queries by default. CodeQL comes with several pre-defined query suites. The most important ones are code-scanning.qls (the default) , security-extended.qls , and security-and-quality.qls (roughly LGTM's default settings).

Thanks that worked out

Hi,

we also would like to report our observations when switching from LGTM to CodeQL, but when I try to create a new issue, the only offer is to privately report a security vulnerability. Do you employ any other means for submitting experience reports?

With kind regards,
Andreas.

Edit: I've discovered the right place to report CodeQL False positive(s), it is on the github/codeql repository, at https://github.com/github/codeql/issues/new/choose. Thanks.

@amotl, you can create a blank issue by using the link at the bottom, or just going here.

Thanks. In this case, I've created github/codeql#11407 and github/codeql#11408.

Other than this, everything on the transition went very smoothly with crate/crate-python#467 and crate/crash#373. Thank you very much for the efforts you are putting into this!
