Thanks a lot @vivekjoshi556, I will take a look first thing next week, now OOO.

[vivekjoshi556]

Hey @mman. Just wanted to check if you got some time to look at the PR.

[mman]

@vivekjoshi556 The code looks nice and clean, the tests as well. Will try to deploy to my stage env later today.

[vivekjoshi556]

Hey @mman Just wanted to check in again.

@mtrezza if you have inputs as well, please let me know.

There is a minor issue with linting I'll fix it in the next push, anything else let me know.

[mtrezza]

This fix just shifts the problem downwards from 24 hours to 1 minute. Because for a session length of <1 minute, the problem in #8981 persists.

I wonder whether we need such a complex logic for this. If I understand #8981 (comment) correctly, the purpose of this logic is to find a middle ground between:

• extending the session on every request --> con: high DB writes
• ensuring that the session extends before it expires --> con: session would never get extended

Wouldn't it be simpler to extend the session when the remaining session token validity time reached < 50% of the session length?

For example:

• session length 1 year --> session extends if remaining time is < 182 days
• session length 1 day --> session extends if remaining time is < 12 hours
• session length 1 hour --> session extends if remaining time is < 30 mins
• session length 1 minute --> session extends if remaining time is < 30 secs

Pros:

• Simple to document and understand
• This adapts dynamically to the session length, instead of some arbitrary extension trigger times
• It's easy to make this configurable via a new Parse Server option in the future, by letting a developer configure the threshold, e.g. 50% as in examples above.

And could you please document this new behavior in the Parse Server option extendSessionOnUse?

[mtrezza]

@vivekjoshi556 Just a friendly ping here; if you could simplify the logic and add the functionality description to the option docs (this repo, not the docs repo), then we could go ahead and merge.

[vivekjoshi556]

So sorry just got a bit swamped with work. Give me some time
