Have you ever felt that administering your GitHub organisation (or
organization, depending from where you hail), its repositories, teams,
and service hooks has become a tedious task and that you’d rather be
doing something else? Maybe you’re of the mindset that there should be
a better way of doing things - a way that involves specific,
version-controlled configuration and less repetition (less
clicky-clicky). The good news is that there is — github-collective!
This is a script, written in Python, that utilises GitHub’s JSON-based
API to allow you to construct an ini-style text-based configuration
representing your GitHub organisation and …
This is a mirror of the (excellent) documentation at
but just a short editorial to also highlight that this is still very
applicable to Plone 4.x. Effectively, the symptom is that users will
report seeing a “401 Unauthorized” error when trying to create folders
within areas they have access to as an Owner. Without further ado, the documentation:
Using a WebDAV client on a Plone site, site users are unable to create
newfolders directories where they have Owner role.
The WebDAV “make folder” method, MKCOL, requires the “Add Folders”
permission. This is …
If you’ve migrated your site from earlier versions of Plone to the
latest ones in the 4.x series, or else have started using
plone.app.discussion earlier than that, you might have come across a
situation where comments on your site show user IDs as authors rather
than a user’s full name. If you see this anywhere, chances are your
comment’s migration didn’t go according to plan, and that the Creator
information didn’t get recorded correctly on the comment.
In case you were ever curious, it’s definitely possible to upload
epic-sized files within the Plone CMS. Browser support aside (Firefox
and your 2 GB limits, I’m looking you), I’d previously had issues with
being able to upload files larger than 4 GB, if memory serves correctly.
Previously, there was an issue with files causing out-of-memory issues,
and I’m fairly sure the errors I was getting were related to what was
fixed by this change.
For today’s test, Google Chrome was able to upload a 26.3 GB
(28212643840 bytes) .tar file into Plone on …
Today was interesting when an issue with saving content on a Plone 3.3.5
site got reported to me. The system was producing undecipherable error
messages about ZEO disconnections and database conflicts whenever
someone would try and create some content within Plone (folders,
particularly). Errors looked like:
Module ZEO.zrpc.connection, line 796, in wait. DisconnectedError" and "raise ReadConflictError().
ReadConflictError: database read conflict error"
Today, I needed to migrate some legacy Plone installs set up using
Buildout. If I were to simply move the buildout files and re-run
buildout, I’d end up with the latest versions of add-on products - and
since I’m using legacy versions of Plone 3, that’d almost certainly
break the system. I do know about the Buildout extension
buildout.dumppickedversions (which does what its name suggests and
exports picked versions of eggs) but I can’t re-run buildout to get this
extension for risk of updating existing products (what I’m trying to avoid!).
After upgrading from Ubuntu 10.10 (Maverick Meerkat) to Ubuntu 11.04
(Natty Narwhal), you’ll probably find that if you’re running a Plone 4
buildout where you need to upgrade the Plone version, that compilation
of Zope will fail. The output will look something like this:
Getting distribution for 'Zope2==2.12.17'.
In file included from src/AccessControl/cAccessControl.c:51:0:
include/ExtensionClass/ExtensionClass.h:83:20: fatal error: Python.h: No such file or directory

What you may notice if you’re developing with Plone/Zope, is that if
you’re storing small pieces of data within Plone’s session variable (the
session_data_manager tool), data expires after a few minutes. By
default, this timeout is 20 minutes, but is far too short if you’re
expecting the information stored to last for say the whole time a user
is logged in. In this situation, you’ll need to increase the timeout.
Documentation on changing the session timeout is potentially a little
sketchy (Google “session-timeout-minutes zope”), but it’s clear that you
need to change the …
It’s my very last Plone 2.5 site and I’m very happy to see the back of
it. Using the joy that is quintagroup.transmogrifier, I was able
to, without much manual effort, migrate my content from a Plone 2.5 site
(constructed with instancemanager, of all things!) straight into a shiny
new Plone 4 site on Buildout.
My only key need was to port the content and structure, and I was happy
to make big allowances for the sake of certain content and time. So, my
thoughts here mightn’t (probably won’t!) suit everyone.My requirements …
