From 42b75b897add6ab295c18dfc4ce9937e4a212b3e Mon Sep 17 00:00:00 2001 From: Chris McDonough Date: Thu, 21 May 2009 01:44:33 +0000 Subject: - Removed the pickling of ZCML actions (the code that wrote ``configure.zcml.cache`` next to ``configure.zcml`` files in projects). The code which managed writing and reading of the cache file was a source of subtle bugs when users switched between imperative (e.g. ``@bfg_view``) registrations and declarative registrations (e.g. the ``view`` directive in ZCML) on the same project. On a moderately-sized project (535 ZCML actions and 15 ZCML files), executing actions read from the pickle was saving us only about 200ms (2.5 sec vs 2.7 sec average). On very small projects (1 ZCML file and 4 actions), startup time was comparable, and sometimes even slower when reading from the pickle, and both ways were so fast that it really just didn't matter anyway. --- docs/narr/views.rst | 12 +++++------- 1 file changed, 5 insertions(+), 7 deletions(-) (limited to 'docs/narr/views.rst') diff --git a/docs/narr/views.rst b/docs/narr/views.rst index 87f191a3e..ecaa9784b 100644 --- a/docs/narr/views.rst +++ b/docs/narr/views.rst @@ -186,13 +186,11 @@ After you do so, you will not need to use any other ZCML to configure decorator to do this work. .. warning:: using this feature tends to slows down application - startup, as the application registry is not capable of being cached - within a ``configure.zcml.cache`` file when this package is in use, - and more work is performed at application startup to scan for view - declarations.
