[possibly OT] html2pdf on zope
by AM 19 Mar '03

19 Mar '03

I followed the instructions here : http://www.zope.org/Members/mjablonski/howtoPDF to set up on the fly html2pdf conversion. the question I have is that do I have to have filenames ending in .html for it to work. To view the error generated please see: http://nbs.neuro-bs.com/index_html/html2pdf on IE On netscape/mozilla it pops up a box that says that the file doesnt start with %pdf Any ideas as to what I can do about that??

ZServer and MySQL: wierd behavior
by AM 19 Mar '03

19 Mar '03

I found a strange problem on my install. I run Zope 2.6.1 (Zserver) behind Apache 2.0 on a dual processor RedHat 7.3 box and have a MySQL 4.0.1 db (uses InnoDB tables) that keeps my user data. I have custom user folder based heavily on the mysqluserfolder product that authenticates users off the db. I also have a sign-up process that is a multiform page and uses transactions to insert data into the db (separate from the user folder, the userfolder interfaces for the same are just dummy functions). What I saw was that if for some reason mysql deadlocked over multiple transaction writing to the same table (ie multiple users signing up at the same time on the site) and dropped some of the transactions, Zope just waited around forever and eventually became unresponsive. Apache then returns a 502 - Server overload/busy. Once I dropped the transaction commands (begin/commit) everything worked smoothly. What I would like to know is that if MySQL recovered gracefully why was Zope waiting around for the dropped transactions to return something.?

formatting dates
by Michael Guerrero 19 Mar '03

19 Mar '03

Hello, I am having problems formatting a date that I select from my oracle database. The field is an oracle DATE field. I want to display it as MM/DD/YY. I have tried: <dtml-in sql_get_invc_date> <dtml-var invc_date fmt="%m/%d/%y"> </dtml-in> The formatting works fine when I use ZopeTime but not when I use a dtml-var. I appreciate your help. Thanks.

problems with init-script
by johan 18 Mar '03

18 Mar '03

I work on debian, and i am pretty new with zope (version (2.6.1) . I use the -deb vesion. It looks very fine, but I have problems with the init-script. When I do /etc/init.d/zope start, the server starts, but he keeps hanging on the points. At the server itself it is no problem, because you can let the terminal session open, but the problem is that this occurs at the booting process (init.d before launching the network interfaces), which causes the server hangs. So is there a solution for those processes ? /etc/init.d/zope restart Starting Zope... thx a lot Johan

ECMAScript 262 - Mozilla, IE5/6, and Opera tend to stick fairly close to this, enough so as to be considered ECMAScript compliant. So that if you pay attention to the standard that you can write code pretty much oblivious to what browser it's going to be implemented on. If a browser doesn't support a particular feature like array.push, it's more than likely that someone already has a free prebuilt crossbrowser script that fills the void with no fuss. Additionally if you're using javascript for the sparkly factor then your using it wrong, go use flash or java applets. WE use it in form validation, table sorting, row hit highlighting and client side pagination and creating lightweight user interface components like tabpanels. It works easily with about 5 major browsers and there's no "IF IE6" or "IF NS4" anywhere in code. My point is that NOTHING we have today works IDENTICALLY in every browser. IE will render font's one size and moz another and lynx another. If your criteria for using a standard is how identically it works in each browser then you won't be using any standard. Additionally you have to design pages that should javascript/css/xml/xsl/whatever not be available that you have a plan B. >From: martin f krafft <madduck(a)madduck.net> >To: zope(a)zope.org >Subject: [Zope] Re: Re: Re: pulling from another website >Date: Tue, 18 Mar 2003 22:34:41 +0100 > >also sprach Michael Havard <nhavar(a)hotmail.com> [2003.03.17.2205 +0100]: > > Sorry but what a complete crock of elitist crap.

performance problems
by Jerome Alet 18 Mar '03

18 Mar '03

Hi, during a training session this morning, I told the seven students to install Zope on their personnal account on a Samba server from their W2K workstations but to run it "locally" through the network. network is full-duplex 100 MBits/s, workstations are 1.8 Ghz PIVs with 768 Mb RAM, server is Bi-Xeon 2.4 Ghz with 1 Gb RAM, and a raid5 array, under Linux. When each student started his Zope instance, I found that performance wasn't impressive at all, and that Samba used a lot of CPU ressources. It worked though, and I see no error or warning in Samba's log files. Is it "normal" ? (this was the first time I used such a configuration, the room is brand new) Does someone use such a configuration ? What are the performances ? AI suspect something abnormal because I use Samba since 1996-97 and I don't remember having seen such a CPU ressources use. My office server is actually a PPro 200 Mhz with 128 Mb RAM and serves 8 stations without problems (not with Zope, though) On the other hand this may be that the way Zope uses the ZODB, particularly at startup time, is really ressource intensive on the Samba server. Could anyone report similar or different experiences ? Is there a parameter to change on the Samba server to improve Zope's performance ? Thanks in advance Jerome Alet

session_data Users Online?
by centershock＠t-online.de 18 Mar '03

Ahoi... Remark ahead, I know that "http" is a connectionless protocol, but does somebody know a hack to find out how many users are online in Zope!?! I cheked out the Session Modules in Products but can't find a Methode that works. For hints or a tutorial_link I'm very gratefully to you all. Oki, have a nice day and remember... Support the newbies, they are resources for the future. cYa

Is Logout actually impossible? (ExUserFolder)
by Crosbie Fitch 18 Mar '03

18 Mar '03

Is it just me, or is logout actually impossible? Once you're authenticated with ExUserFolder (on a subfolder), it seems near as dammit impossible to become un-authenticated - I've tried quite a few permutations (standard authentication & cookie based). This doesn't work: <div tal:define="dummy python:here.acl_users.logout(request)" /> Nor does this: <div tal:define="dummy python:request['RESPONSE'].expireCookie('__ac',path='/')"/> NB What should 'path' be here? Sure, you can redirect to a folder above the XUF acl_users, e.g. to the root: <div tal:define="dummy python:request.response.redirect('/loggedout')" /> but that doesn't stop the user going back to where they were and remaining authenticated. I've read in some places that it's all IE's fault, for not destroying the session info, but I'm using the latest version of IE, so that seems strange. Do PHP users have this problem too, or is it just Zope? I can get registration and login working just fine. It's just logout that's tricky.

"javascript is evil. moreover, this won't work if someone browses the site with e.g. lynx." Sorry but what a complete crock of elitist crap. Javascript, just like any other client side code, has it's uses (and abuses). Saying that Javascript is evil even in part because it can't be used by browsers like Lynx is equivelant to saying that CSS/Graphics are evil because the blind can't see them. Or that HTML 4.0 is bad because IE3 and NS4 don't implement it well. Yes there are alot of script kiddies and even professional designers out there that use the propritary extensions (both MS's and Netscapes) and cause sites to be inaccessible to certain users. I think instead of bashing the language we should advocate better use. Let's keep blanket statements like "XXXXX is evil" out of the groups and focus on helping developer create better more accessible content using ALL of the tools at their disposal. _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963
