Package: plone.reload
OverviewConfiguration and code reload for Zope 2 and Plone without server restarts.UsageWhile being logged into the ZMI as an user with the Manager role visit/@@reloadon your Zope application root via a browser. If your Zope is
configured to listen on port 8080 on localhost this is:http://localhost:8080/@@reloadIf you get aResource not founderror, make sure you have loaded theconfigure.zcmlfile from this library and you really use the ZODB application
root and not a Plone site as the base url.When you press theReload Codebutton, 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.Caveats: There’s some code structures which cannot be reloaded via the
approach underlying this library. Plone portlets and content types are two
examples of this. In general decorators will currently not always work.DevelopmentThe code and issue tracker can be found on GitHub at:https://github.com/plone/plone.reloadThanksThis code is heavily based on theProducts.RefreshNGproduct found athttp://launchpad.net/refreshng.The originalxreload.pywritten by Guido van Rossum can be found athttp://svn.python.org/projects/sandbox/trunk/xreload/xreload.pyIt 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.ContributorsHanno Schlichting (primary author)Martin Aspeli (test contribution)Changelog3.0.2 (2021-10-16)Bug fixes:Fix a deprecation warning [ale-rt]Fix missing doctype, add html lang, use html5 charset to reload page.
[thet]3.0.1 (2020-04-22)Bug fixes:Minor packaging updates.3.0.0 (2018-11-05)Call invalidate_caches and remove the __pycache__ in Python 3Add Python 3.4, 3.5 and 3.6 support. Drop Python 2.6 support.Test against Zope 4, while keeping compatibility with Zope 2.13.2.0.2 (2016-08-18)Use zope.interface decorator.
[gforcada]2.0.1 (2016-02-11)Minor packaging fixes.  [gforcada, maurits]2.0 (2011-06-04)Update test assertions to avoid deprecation warnings under Python 2.7.
[hannosch]Relicensed to BSD.
[hannosch]Minor PEP8 cleanup.
[hannosch]Exclude tests from the shipped source distribution.
[hannosch, iElectric]2.0b1 (2011-04-03)Require at least Zope 2.12 / Python 2.6 and add preliminary support for
Zope 2.13 with Python 2.6 and 2.7.
[hannosch]1.5 (2010-07-18)Update license to GPL version 2 only.
[hannosch]1.4 (2010-05-27)Fixed some tests that relied on a specific directory layout.
[hannosch]Fixed a bug in dealing with class descriptors, like Five’s BoundTemplateFile.
We replaced the descriptor with the descriptor result, leading to strange
problems. We check for those by looking directly into the__dict__and
comparing it to the result of a normalgetattrcall.
[hannosch, optilude]1.3 (2010-01-16)Use a different hook for providing the initial setup of tracked code files.
In Zope 2.12+ there’s a proper event published right before the process has
started. If this is available we use it, instead of our no longer working
approach to hooksetupFinalLogging.
[hannosch]1.2 (2009-11-21)Moved the template reloading support into an extra.
[hannosch]Added test_suite functions to the test modules.
[hannosch]1.1 (2009-10-19)Added CMF specific functionality: We support explicitly reloading all file
system based objects from skins folders while running in production mode.
[hannosch]1.0 (2009-10-11)Avoid theENABLEDconfig flag and check against Globals.DevelopmentMode in
the browser view.
[hannosch]Make sure the import of the Globals module happens after the variable has
been set. This should make it compatible with Zope 2.10.9+.
[hannosch]1.0b1 (2009-08-11)Got the test coverage for the code reloading part up to 100%.
[hannosch]Fixed reloading of the module scope. The func_globals of functions is now
updated with new names introduced into the module scope, so adding new
import statements will work.
[hannosch]Specified package dependencies, added development buildout and added
extensive test coverage.
[hannosch]Figured out a way to support reloading code that uses decorators.
[hannosch]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 willnotdisappear 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 aZope is finished loadingevent 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 fromhttp://bazaar.launchpad.net/~refreshng-dev/refreshng/dev.
This fixeshttps://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.
