zserver and pdf's from buffer
by Jason.Jones＠awl.com 13 Apr '01

13 Apr '01

I have PDF files stored in an Interbase database that I am retrieving with gvib from an external method. The result is a buffer object that I would like to output to the browser so that the acrobat control opens to display it. All I get though is the text of the pdf stream. I am setting the response content-type to application/pdf and I am using response.write() to stream the buffer out. Is this wrong? Do I need to create a temporary external file and send that instead? Thanks, Jason

Recover Data.fs from ZEO caches?
by cg＠cdegroot.com 13 Apr '01

13 Apr '01

Simple question: is this possible? I somehow lost Data.fs, but the ZEO caches are quite well fed, and so I want to see whether I can at least partially rebuild Data.fs from the caches. -- Cees de Groot http://www.cdegroot.com <cg(a)cdegroot.com> GnuPG 1024D/E0989E8B 0016 F679 F38D 5946 4ECD 1986 F303 937F E098 9E8B

Re: [Zope] dtml-var AND dtml-tree
by Danny William Adair 13 Apr '01

Hi Dieter! Hi all others that commented! Thank you for reading and commenting. Actually, I first wanted to add a "urlparam_expr" to handle this parameter (consistent naming), and I looked at branches_expr... I didn't understand it: args['branches_expr']=VSEval.Eval(args['branches_expr'], expr_globals).eval Just copying this part (renaming branches_expr->urlparam_expr, of course) rendered to something like <method at ...> (probably very easy to solve, but - like with everything - not if you don't know) so I just took the shortcut with "md.getitem()" to get the parameter from namespace. Then again I thought "urlparam_expr" would no longer be a good name, since it doesn't accept expressions, hence the new name "urlparam_var"... As soon as somebody tells me how to solve this part (accept python expressions and evaluate them) I will put the patch in the Collector. In the meantime I *wanted to* wrap it up as some kind of "hotfix product", so no one has to mess with patching the python sources. Unfortunately... TreeDisplay's __init__.py - which in return calls TreeTag.py's Tree.__init__.py - gets called before my product's __init__, and I don't know how to override an __init__ (I think it's impossible, and it would make sense, too). Sorry. Any hints? Or is it really impossible? Thx for your comments, Danny >>> -----Ursprungliche Nachricht----- >>> Von: Dieter Maurer [mailto:dieter@handshake.de] >>> Gesendet: Freitag, 13.

Dangerous "cvs update" (second report)
by Dieter Maurer 13 Apr '01

13 Apr '01

I was a bit too fast. Yesterdays "cvs update" seems to have almost destroyed my Zope installation.... Now, I get a "Z2 CONFLICT Competing writes at, /manage_menu", as soon as I try to open the management screen. "ConflictError: '\000\000\000\000\000\000Fk'" What wants to write to "/manage_menu" when I only open the management screen? Dieter

The Owner Role
by Ulrike Ainser 13 Apr '01

13 Apr '01

Hi, to add a new user I have to name the user, to specify a password and to give it a role. In the standard Zope installation I can choose a Manager or a Owner role. Until now I understood that every user who created an object is the Owner of that object and has got the same permissions as a manager for that object. Am I right? What I do not understand is the Owner Role I can add to a user. What is the purpose of that role? Thanx, Uli __________________________________________________ Ulrike Ainser - uli(a)highq-it.de

Connecting to Postgres on a Linux Machine From A Windows NT4 Machine Running Zope
by Steven Grimes 13 Apr '01

13 Apr '01

All, I've done quiet a bit of research and I'm still not sure how I can connect to a Postgres 7 Database Running on a Red Hat 7 box from my Windows NT machine running Zope 2.3.1. I do NOT want to use ODBC if possible. I've read about Psycopg, Pygresql and Popy and I'm not sure if these should be installed on the Linux machine or the NT Machine. I'd also like to know which has the best performance and stability. I know I'm asking for a lot of information and I thank anyone willing to help in advance.

Re: [Zope] Two Pythons and PIL module newbie question..
by Chris Beaumont 12 Apr '01

12 Apr '01

Jim, I am sure you are right, but I am not of a mind to reinstall my whole system right now for the sake of making thumbnails.. :( Maybe in two months, when I have a little break in my (very busy) work schedule.. So, is there any way I can install PIL into the working Zope (binary) install, or use symbolic links to make Zope see the deb-installed PIL? (my working zope install was installed from the Linux binary, non-deb, that was available from zope.org) Thank you, Chris Jim Penny wrote: > > On Thu, Apr 12, 2001 at 02:26:46PM -0700, Chris Beaumont wrote: > > Hello, > > > > I'm sorry to ask such a dumbish newbie question.. > > > > I am using the Zope binary release on a Debian Linux system.
