Better ZDOM examples? (take two)
by Benjamin Isaac 02 May '06

02 May '06

Looks like I initially posted this on the wrong list so here I go again.... I'm using Zope version 2.5 My problem: I need to access the DOM. I need to pass a value from a form field to a python script. I've been trying to avoid this intersection for quite some time, using creative alternatives to get around the problem. However, I'm having difficulty avoiding it this time. I found something interesting: ZDOM. Looks promising, but I don't know what the heck I'm doing since the documentation is so laconic and sparse. The example provided is too general for me. I need a working, practical example. I'm not sure if 2.5 implements ZDOM. If so, has anyone used it yet? If someone has used it, then perhaps that someone could send me a code snippet as an example? Thanks for your time.

Forests of symlinks are > not the easiest things to manage. Yeah it's pretty ugly. No doubt it's because dzhandle(1) tries to be all things to all men: dzhandle is the command-line utility for handling Zope servers, instances and products. It is a system administration tool and a Debian/Ubuntu maintainer’s helper script at the same time: using dzhandle you can manage your Zope installations, create [and remove] instances, add [and remove] Zope products to them [and] start and stop them, [and] it [can] also used by the Debian/Ubuntu Zope packages for their installation and removal. It doesn't mention versions above but it supports multiple versions as well and it _is_ very easy to use. For instance, installing CMF1.5 (and creating the directory structure and forest of symlinks) was a one liner: $ dzhandle -z 2.8 add-product z286one CMFCore CMFDefault ... Ah! And I've just remembered, you can chose whether to create symlink files, directories or create copies. More from dzhandle(1): -t ATECHNIQUE, --addon-install-technique=ATECHNIQUE How to install addons: ‘linked’ means the product or extension directory will be symlinked into the instance home, ‘tree-linked’ means the directory structure will be re-created and then files sym‐ linked, ‘copied’ means the file will be copied into the instance home. I handn't grokked this when I issued the command and 'tree-linked' is the default. All in all, it seems like a pretty useful tool. sdt

Converting from week no. to date
by Jonas Nielsen 02 May '06

02 May '06

DateTime().strftime("%U") converts from date to week no. Is it possible to convert from (week,year,weekday) to a specific date in a python script in zope ? I could install the mx.DateTime module in python and then make a product with a method that used ISO.Week() but is there a more straight forward approach ?

ZEO ClientDisconnected error
by Cyrille Bonnet 02 May '06

02 May '06

Hi there, One of my clients is using Plone on Solaris 9. We have set up one ZEO client on a Solaris machine and a ZEO server on another Solaris machine (for testing purposes only at this stage). Performance is great but every morning, the first hit to the Plone site returns a ClientDisconnected error (see full error log below). It looks like the socket on the server gets corrupted or something. When the error occurs, the server is non-responsive for a while (anywhere between 10 sec and 2 minutes) and then eventually the server responds. Has anybody seen that before? Is it Zope related or should I look in other directions? Researching Zope on Solaris, I read somewhere (can't remember where now) that Solaris doesn't like long-running processes too much (well, the Zope process, for instance). Could it be the culprit here? Any advise or pointer welcome.

Windows Server 2003, II6 and ASP404 vs form posts
by Steve McMahon 01 May '06

01 May '06

Anyone out there using Zope inside IIS 6 on Server 2003 via the ASP404 technique? I've done this successfully on Windows 200 and XP, but on Server 2003, IIS does not seem to be passing the post data to the error handler. When Win2003 was young, there was some list traffic on a similar problem, and Brian Sullivan figured out that IIS was reporting a REQUEST_METHOD of "GET" even for POST requests. However, the POST data was still passing, so it was possible to check Request.totalBytes (this is the ASP Request, not Zope's) to determine the real nature of the request. Now, though, many an IIS patch later, IIS is invoking the error handler with http content length set to zero (even though it reports that content type is www-urlencoded). So, form submissions do nothing. And, if there's nothing to be done about this, does anyone know if the Fresh Logic or Enfold ISAPI solutions have any way to intermix serving of IIS and Zope content? If I didn't have to do that, I'd be using Apache, and be done by now ;) . Thanks!

Missing content! Urgent
by Michael Havard 01 May '06

01 May '06

We're missing 16 days worth of content. Python 2.3.5, Zope 2.8.4, Plone 2.1.2, and a host of other products. ZEO configuration. Persistent disk caching is on. Yesterday everything was fine. All the content was there and accessible. Today I try to log in and the server doesn't respond. I go out and restart the zope client, still no response. I restart the zeo server and the site delivers content. Problem! The content is from two weeks ago. All of the content from the last 16 days is missing. Thinking maybe someone restored from an older backup I went out to our daily backups and pulled the previous days data.fs backup. A restore didn't work. It still shows the outdated content. I went out to look at the backups again and noticed that the date on the data.fs was 4/14 while the date on data.fs.tmp was 4/26. data.fs.tmp is a 9 meg file. Is the missing content somehow captured in data.fs.tmp or is it somewhere else that I can retrieve it? If it is how do I get it back?

LAST INSERT ID driving me crazy
by Alric Aneron 01 May '06

01 May '06

Hi guys, HOW HOW HOW HOW!!! Do I get at the last_insert_id() function, this is driving me absolutely crazy!! Zope docs say use "select last_insert_id()" but it doesn't work, gives me an error about bad SQL syntax around "LIMIT 1000". I tried googling it, I tried searching through other docs. And it just won't do it! I would like to make a separate ZSQL Method that will return to me the last insert id. Any help would be appreciated. Thank you. --------------------------------- Yahoo!

FileStorage backup semantics are now "nice" with repozo, how would you back up related blobs? I guess I also have an irrational paranoia about separate files having the correct transactional semantics. Anything I can read to prove my paranoia to be irrational? ;-) cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
