plone.reload Configuration and code reload without Zope server restarts. plone.reload ============ Overview -------- Configuration and code reload without server restarts. This code is heavily based on the Products.RefreshNG product found at http://launchpad.net/refreshng. The original xreload.py written by Guido van Rossum can be found at http://svn.python.org/projects/sandbox/trunk/xreload/xreload.py It has some enhancements, but those seem to break more code than do any good in a Zope environment with patched in meta classes and monkey patches all over the place. Usage ----- While being logged into the ZMI as a Manager user goto /@@reload on your Zope application root via a browser. If your Zope is configured to listen on port 8080 on localhost this is:: http://localhost:8080/@@reload If you get a `Resource not found` error, make sure you have loaded this packages configure.zcml file and you really use the ZODB application root and not a Plone site as the base url. When you press the `Reload Code` button, all modules that have been changed since the last time they were loaded are reloaded. You'll get a status message telling you which modules have been reloaded. To reload all ZCML without a restart, press the 'Reload Code and ZCML' button. The action to perform is determined via a simple query string, so once you did a 'Reload Code' once, you can simply reload the browser page to execute the action once again. Changelog ========= 0.11 (2009-05-30) ----------------- - Added the z3c.autoinclude entry point so that plone.reload is automatically loaded on Plone 3.3 and above. [optilude] 0.10 (2009-03-22) ----------------- - Do not remove attributes from classes when reloading. ZCML directives and other wiring is liable to add attributes to class that will then disappear on reload. This means that if you have removed a class attribute, it will *not* disappear on reload. In this case: restart. :) [optilude] 0.9 (2008-07-23) ---------------- - Removed the manual cleanup approach for extra registries populated by ZCML parsing. Instead we use the registry of cleanup functions inside zope.testing.cleanup to automatically pick up all cleaning functions. [hannosch] 0.8 (2008-06-30) ---------------- - Wrap the setupFinalLogging method of the Zope2 starter objects to initialize our internal modified times registry once after Zope is finished loading. This is the closest I could find that resembles a `Zope is finished loading` event and should help to remove the double-reload behavior. [hannosch] - Only expose the reload view in Zope 2 development mode. [hannosch] - In case of errors during ZCML reload, restore the original global site manager state, instead of leaving it in a broken state. This allows you to fix and retry the ZCML reload as many times as you need. [hannosch] 0.7 (2008-06-17) ---------------- - Merged the two distinct views into one called @@reload. Added a somewhat nicer UI to it and explain some of the current limitations on that page. [hannosch] - Refactored ZCML loading code a bit. Always do an automatic code reload before reloading ZCML. [hannosch] - Removed all blacklisting code. [hannosch] 0.6 (2008-06-11) ---------------- - Disabled blacklist until it can be made configurable. The speedup is hardly noticeable anyway, and it can block too much (especially if plone.reload is being used in a lib/python style deployment rather than as an egg). [optilude] 0.5 (2008-05-24) ---------------- - Merged r20 from http://bazaar.launchpad.net/~refreshng-dev/refreshng/dev. This fixes https://bugs.launchpad.net/refreshng/+bug/175898. [hannosch] - Removed various levels of caching which turned out to be premature and caused lots of modules not to be found. [hannosch] 0.4 (2008-03-01) ---------------- - Made the code reload available as its own @@code_reload view. [hannosch] - Integrated xreload.py from RefreshNG and added a first working version of a general manual code reload feature. [hannosch] 0.3 (2008-02-21) ---------------- - Fixed caching issues by invalidating all ZODB caches. If you have local site managers spread across multiple FileStorages this might still not work as expected. [hannosch] - Added cleanup for CMFCore and PAS. [hannosch] 0.2 (2008-01-25) ---------------- - Added compatibility with Zope 2.10 / Plone 3.0. [hannosch] 0.1 (2008-01-25) ---------------- - Initial implementation based heavily on Products.RefreshNG. [hannosch] - Initial package structure.
