Invalid version reported for version strings ending in -latest

[DABH]

Versions

• NodeJS: 16, 18, 20
• mongodb-memory-server-*: 9.1.3
• mongodb(the binary version): 0.0.0
• mongodb(the js package): 0.0.0
• mongoose: 0.0.0
• system: Ubuntu 22.04 LTS

package: mongo-memory-server(-core)

What is the Problem?

My CI pipeline refers to MongoDB versions like "v6.0-latest". This worked with mongodb-memory-server(-core) 8.x, but it seems like it no longer works in 9.x (9.1.3, at least).

Code Example

Here's where we define the MongoDB version strings in our repo, for our CI pipeline: https://github.com/winstonjs/winston-mongodb/blob/master/.github/workflows/ci.yml

Debug Output

Please see the GitHub Actions output here: winstonjs/winston-mongodb#259

Do you know why it happens?

No, but my guess is it may be something similar to #734, where some code maybe slipped in between 8.x and 9.x that adds some semver comparison that doesn't sanitize for -latest?

Thanks so much for helping track this down, let me know if there's any other info you need from me!

thanks for reporting, issue is quite obvious: v6.0-latest is not a valid semver version and was not coerced to one beforehand, and since 9.0 there are checks against the version to decide the default storage-engine to use, because mongodb 7.0 removed the ephermeralForTest(in-memory) engine, which is faster than wiredTiger and so is still used as a default for lower versions
