<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">As recently discussed on the mailing list, it is currently unnecessarily difficult to handle the following scenario:
File A does something like "import B"; you want A to be parsed with the top-context for B available.
Various language plugins have various solutions for this problem, but none of them were considered optimal by their creators (as far as I understood).
This patch aims to adress that problem. It changes the parsejob creation algorithm by enforcing it to wait with creating a job with a worse priority as long as jobs with a better priority are still running. Example: Three documents A, B and C are scheduled for parsing, A and B with priority 0 and C with priority -1. Assuming two parse jobs are available, the old function would create two parsejobs for C and A or B (let's say A), then wait for one of them to finish, then create a third job for B. The new function will create a parsejob for C and wait until that one is finished, and then create two jobs for A and B (still simultaneously, because they have the same priority). In other words: It's guaranteed that all parse jobs running at any specific time have the same priority. (*)
Why is that useful? Because parsejob priorities can be used to adress the above problem now: Let priority(x) be the priority of the parse-job for document x. You can then parse A, and as soon as you encounter the "import B", you can schedule B with priority(A)-1 and schedule A (again) with priority(A). That's now guaranteed to first parse B and then re-parse A with the top-context for B being available.
Oh, this patch also adds a function to get a parseJobs ownPriority(), that wasn't available before.
Please tell me what you think.
Greetings,
Sven

(*) I'm aware of the fact that this will decrease performance by a little bit. However, I'm pretty sure it's not relevant. If the general concept of this is accepted, I'll test it.</pre>
