Subject [jira] [Commented] (COUCHDB-1075) Circular require's in CommonJS modules
Date Tue, 03 May 2011 16:03:03 GMT


Caolan McMahon commented on COUCHDB-1075:

If I understand you correctly, you're suggesting compiled modules are stored as a property
on the string containing their source code in the design document? That would work fine of
course, but I thought having a separate module_cache made it easier to clear between requests.
Now I think we should persist the cache between requests and if that's the case, storing it
on the design doc probably makes more sense :)

If we accept a more persistent cache, then you're right to point out that we need to make
sure it's cleared when the design doc changes. This wasn't a consideration when the cache
was cleared between requests, so I didn't add a test for it. I'll update the patch to include

Thanks for the feedback

> Having a CommonJS module A which requires B, when B also requires A causes the stack
to fill up with require calls. A prerequisite for this fix is the caching of modules, even
if it is only on a per-request basis.
