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 step in and fix your mistakes. For the uninitiated, a loose recursive wget (when logged in with some degree of Edit rights) will hit every link that’s on your pages, and I mean in the (X)HTML source. For a Plone site, this means hitting every “Edit” link, every “Revert to this version” link, and every other link that might be dangerous when clicked randomly. Oh, and if the account you’ve got has admin rights, well, it’s not getting any better and requires the Data.fs to be undone back to before it happened. Here’s how to do that easily. (more…)

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 eating HDD space), deleted them. Whoops..they’re gone and their references are still in your Plone database. Or, in a less disastrous situation, maybe you just want to be able to run your Plone database without needing lost blobs? Read on. (more…)

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 other hand, these types of groups are quite common in LDAP implementations; not supporting them without giving it at least half a shot to find the user seems a bit strange.

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 this distributions has pretty much called for its own post on the matter of getting a working Plone 3.x / Python 2.4 virtualenv installation going.  So, here goes this time around.

Whoops.  No one sent me the memo that Python 2.4 support was being removed entirely from the latest version of Ubuntu, 10.04 Lucid Lynx.  To be fair, I was presented with the message that ‘these outdated packages will be removed’ and in that list was python2.4.  I made the unfortunate assumption that this just mean the package was outdated (which it certainly is) and I’d have the ability to install it again in Lucid.  There were a number of different packages on the list and in order to save time, I let the updater remove them all.  End result?  No more Python 2.4 on Lucid.
