1796250 - Use a unbounded queue for preinit, but have it act like a bounded queue

Status: RESOLVED FIXED

(Data Platform and Tools :: Glean: SDK, defect)

Description

[Perry McManis [:perry.mcmanis]]

We would like to evaluate making the pre-init queue considerably larger (for example, to ameliorate https://bugzilla.mozilla.org/show_bug.cgi?id=1780035), but bounded queues are fully preallocated.

Unbounded queues are linked lists that add 32 nodes at a time. In fact, for most glean initializations, this will create smaller queues, which is great, and also in the case of large pre-init queues, it can grow rather than be pre-allocated.

The only drawback is that if Glean never finishes initializing, it could grow indefinitely.

We will move the size checking to Glean to allow for the potential increase of the preinit maximum queue size.
