can you add an assertion to count the leafs and free pages here? just in case the numbers change in the future - or below, where you're reading the freelist pgids

Added one more check below. We are good as long as the freelist ID isn't empty.
require.Greater(t, len(beforeFreelistPgids), 0)
tests/failpoint/db_failpoint_test.go
Outdated

that's probably a better candidate for a defer

If we use defer, then we have to remove the require.NoError, something like below,
defer gofail.Disable("beforeWriteMetaError")
Note each time a "defer" statement executes, the function value and parameters to the call are evaluated as usual and saved anew but the actual function is not invoked.

we don't have to remove the require to use it in a defer statement, but I'm fine with keeping it the way it is. I'm mostly concerned about a failure in this test impacting the other testcases with the failpoint and then one has to check which one caused the failure to begin with.
It's a separate suite with a few tests, so let's leave it

Updated again,
defer func() {
t.Log("Disable the `beforeWriteMetaError` failpoint.")
require.NoError(t, gofail.Disable("beforeWriteMetaError"))
}()

thanks! /lgtm |
The freelist should be unchanged when TXN rollbacks.
