segmentation fault / EXC_BAD_ACCESS / KERN_INVALID_ADDRESS
when closing DB when a query is in progress
#1323
Comments
@jjhbw Thank you for reporting this issue, it's appreciated! Please PR a test case that reproduces this issue if you have the time, thank you.

I couldn't get it to reproduce reliably so i'm afraid that this example is stochastic: it should crash after a few tries. A longer running query may do the trick in one go. Let me know if you have any questions regarding the details of the setup! |
Oh, wow, just noticed you don't need Electron for this at all! Running the below in Node 14.x crashes with const sqlite3 = require('sqlite3')
const path = require('path')
setInterval(() => {
const db = new sqlite3.Database(path.join(__dirname, 'test.db'))
setTimeout(() => db.all('select * from foo limit 1;', console.log), 1)
db.close(err => console.log(err))
}, 500) |

Tested it with the above snippet. It is still a thing in 5.0.0, I'm afraid. |
Could you try this with #1368? |
@mohd-akram awesome, it seems to work when i build the library from source on macOS. I have made a PR with the test I used (https://github.com/mohd-akram/node-sqlite3/pull/1). It is a rather informal, non-deterministic test case so feel free to discard it if you'd rather use something more formal to verify that this works correctly. The test just tries to trigger the segfault ad nauseam for a few seconds (and successfully does so within <1 sec on master 6e250c6). |
Hi all, thanks for this fantastic library. I have used it with great success in a few projects.
I encountered a crash (
Fatal Error: EXC_BAD_ACCESS / KERN_INVALID_ADDRESS
) when closing the DB while a query is still in progress. I'm running in Electron 8.2.5. No exception was thrown, just a complete crash.Versions used:
Sqlite3:
4.2.0
Electron:
8.2.5
Mac OS X:
10.14.6
I've attached the crash dump as recorded by Sentry
90104e4407e84e8793326bc199d03b4e-symbolicated.crash.zip
AFAIU
sqlite3
should wait until all queries are finished before closing the database, right?Let me know if you want me to build a repro case. This requires a basic Electron setup, as I couldn't get it to reproduce in Node 14x. I don't have the time for that atm, so i figured i'd make this issue first.
I'm not super familiar with Node native extensions, but let me know if you think i can help in any way.
