Oh Microsoft, we do tire of thy bugs in IE

David — Thu, 22 Jul 2010 07:20:37 +0000

Yes, it’s another post about Microsoft and its poor implementation of Internet Explorer. This time it’s version 8 and its rendering of lists, and in specific, links within list items. Most humorously, Microsoft’s own documentation (separate issue; about rounded corners) gave me a laugh when it said “Microsoft is committed to providing a browser that [...]

Plone/Zope: Truncating a Data.fs back to a certain date/time

David — Tue, 20 Jul 2010 03:39:27 +0000

Okay. So, anyone out here who’s listening — particularly those overly-enthusiastic users — don’t try to recursively wget your Plone site (or other CMS, for that matter) whilst you’re logged in with an account that can make edits. It will lead to a very bad situation where your site administrator and technical team need to [...]

Plone: running Plone without copies of blobs

David — Tue, 13 Jul 2010 06:30:00 +0000

Having a bad day? Just bombed your only copies of some files that you’d been storing as blobs together with your Plone database? Maybe you had the blobs stored incorrectly on your Zeo client, rather than the server, and then in a hasty effort to free some space (due to an on-going issue with blobs [...]

Plone: Overrides.zcml gets auto-included with z3c.autoinclude

David — Tue, 13 Jul 2010 05:01:55 +0000

Unsurprisingly, specifying a z3c.autoinclude entry point in your Plone product egg means your ZCML gets automatically included. That’s great because it means you don’t have to specify your product under the ZCML section of your instance in buildout. One thing that isn’t so obvious (it’s not mentioned that I can see on plone.org) is that [...]

Linux: Make time with faketime

David — Mon, 12 Jul 2010 02:02:19 +0000

So you, like me, have hit a situation where you’ve got a time-sensitive application that won’t run? Maybe you’ve downloaded one of those apps (like a demo) that won’t run after a certain date and time because it’s “expired”. Or else, maybe some other arbitrary time constraint is keeping you from running a Linux (or [...]

Plone 4: Local Zeo blobs conflict with Plone instance

David — Tue, 06 Jul 2010 06:04:03 +0000

As the title suggests, there’s a conflict between a Zeo database instance being run together with a Plone 4/Zope instance, and them trying to share the same blob storage folder. But, this only happens if you misunderstand or incorrectly set the option of shared-blob = off, and blob-storage to be the same location as for [...]

Plone: SiteManager leftovers; not the good kind

David — Mon, 28 Jun 2010 04:35:20 +0000

Leftovers are typically useful when they’re in your fridge at home. They mean you don’t have to mess around making lunch for the next day for work, and can just grab them, and walk right out the door. Now, leftovers in the zope.component SiteManager aren’t so nice, especially when some Plone products fail to remove [...]

Plone, Dexterity, and Incorrect Widgets

David — Mon, 21 Jun 2010 05:09:31 +0000

A nice ‘gotcha’ is the distinction between Zope’s schema.Date and schema.Datetime. The difference is obvious and straightforward when the two terms are laid out side-by-side: one is for dates only and the other adds a time component. Where things fell down for me in my usage of these fields with a Dexterity-based content type in [...]

Plone/Zope: Using LDAPUserFolder with posixGroups

David — Thu, 03 Jun 2010 06:03:25 +0000

Due to various reasons, the Products.LDAPUserFolder package available for Plone and Zope doesn’t support POSIX groups. The ‘official’ (ish) reason for this is because of the fact that these groups don’t store full distinguished names (DNs) for members. It makes some degree of sense, because a user ID like ‘david.test’ isn’t strictly unique. On the [...]

Virtualenv, Python 2.4, Plone 3.x and Lucid Lynx (Ubuntu 10.04)

David — Wed, 12 May 2010 04:47:45 +0000

These titles of my posts just keep getting longer and longer. For those of you paying close attention (I know who you are), this is the next in my series of getting the above-mentioned tools working together. Previously, it was Centos 5.x, Jaunty (9.04), Karmic (9.10) and now Lucid (10.04). Only subtly different, each of [...]
