The "aliases" feature of the stock Shared.DC.ZRDB.Results.Results class
has a leak, due to an uncollectable cycle created between the alias
objects and the record class generated *for each query*. If your app
makes heavy use of stock ZSQL methods, you are probably going to have to
plan to monitor the server's RAM usage and reboot as it gets close to
the limit.
If you are confident either that your application does not need the
alias feature (your SQL queries all spell the column names using the
"canonical" spelling for your SQL server), or that you can modify them
to do so, you might try applying the attached patch, which removes the
aliase feature.
Tres.

Is there a subtle difference? Hmm, there seems to be a third way that some packages use: 3. declare your egg to be a 'Products' namespace package, omit any entrypoint or registerPackage declarations and rely upon setuptools splicing you into the Products.__path__ list and being found the conventional way of scanning the (virtual) Products namespace. BTW, I'm working with Zope 2.12.10, and I'm not finding -any- code that searches for a zope2.initialize or zope2.products entrypoint - seems to be a NOP. -Jeff ___ Zope maillist - Zope@zope.org https://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope-dev )
[Zope] Preferred non-Products Initialization Approach?
In my reading I can see there are two ways to initialize a Product that is not sitting in the Products directory: 1. use ZCML with the five:registerPackage directive 2. declare in setup.py a "zope2.products" entrypoint Which is the preferred way these days? Is there a subtle difference? In particular I'm having trouble with an Extensions/ subdirectory of the Product -not- being found in an import stmt when I moved it outside the Products directory. -Jeff ___ Zope maillist - Zope@zope.org https://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope-dev )
