The first two arguments are the same as for stdio's fopen(): filename is the file name to be opened, mode indicates how the file is to be opened: 'r' for reading, 'w' for writing (truncating an existing file), and 'a' opens it for appending (which on some Unix systems means that all writes append to the end of the file, regardless of the current seek position). Modes 'r+', 'w+' and 'a+' open the file for updating (note that 'w+' truncates the file). Append 'b' to the mode to open the file in binary mode, on systems that differentiate between binary and text files (else it is ignored). If the file cannot be opened, IOError is raised. </quote> hth Rik

ZServer+SiteAccess+Apache+SSL
by Wayne Izatt 22 Jun '00

22 Jun '00

I've just managed to get ZServer running behind Apache with SiteAccess (thanks for the how-to, anser!) Now, has anyone managed to configure SSL into a mix like this? Seems to me I should be able to go through the standard SSL setup for Apache, and not worry too much more abou the ZServer component of the architecture. thanks Wayne

System variables
by Matthias Füsting 22 Jun '00

22 Jun '00

Hi, I import a Web Site with hundreds of pages into Zope. Every pages use the folder "icon" for images. As I create a folder with the name "icon", a error message came from Zope. --> Error Type: Bad Request Error Value: The id icon is invalid - it is already in use. I think "icon" is a system-variable. My Question: Is there any possibility to create this folder? Thanks.

Hello, I have two version of zope one is 1.2.2 downloaded as a binary release and another is 1.2.6 downloade as a source from Zope.org. My operating systen is Turbolinux 6.0. I have got the database connection for MySQL only for the veersion 1.2.6 which i had compiled from source.I Both are installed on different computers and working normally. Now my problem is to insert a date type in the properties of folder. The formats like Jan. 07, 2000 January 07 2000 jan 07 2000 2000/07/01 all work well in the version 1.2.2 which is a binary release. But, none of the format works with the version 1.2.6 which i had downloaded as source. The error i am getting with the date type data is as follows. Error Type: Invalid Date-Time String Error Value: january 20, 2000 Traceback (innermost last): File /home/suhail/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /home/suhail/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 179, in publish File /home/suhail/Zope-2.1.6-src/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File /home/suhail/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 165, in publish File /home/suhail/Zope-2.1.6-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_addProperty) File /home/suhail/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_addProperty) File /home/suhail/Zope-2.1.6-src/lib/python/OFS/PropertyManager.py, line 290, in manage_addProperty (Object: ElementWithAttributes) File /home/suhail/Zope-2.1.6-src/lib/python/ZPublisher/Converters.py, line 157, in field2date File DateTime.py, line 518, in __init__ File DateTime.py, line 788, in _parse Invalid Date-Time String: (see above) I have got the database connection for MySQL only for the veersion 1.2.6 which i had compiled from source and has t o use MySQL database which is giving errors when used with binary release.

Re: [Zope] External Method Difficulties

The error message's head should tell you what key has not been found. The traceback at the foot (especially the last line) tells you where the KeyError occured. Dieter

Re: [Zope] Dynamic sorting key?

AFAIK, there is currently no way to treat values for "sort" as expressions. You may try, ... sort="REQUEST['sort_by']" ... (note the "..."!), but it will probably not work. It, obviously, is useful, but I believe nobody has implemented it yet. Dieter

Problem with the datatype "lines"
by Anders Holmbech Nielsen 22 Jun '00

22 Jun '00

Hi Zopers, I have found out that when using the datatype "lines" in my own ZClass it won't obey to the locale settings. That means that the words coming from "lines" look like: t/370nk. And therefore they don't get correctly indexed in the database. I'm running Zope 2.1.6 (on both linux and winnt 4.0). Is there an update to this problem or a workaround ? Thanks in advance -- Regards ------------------------------------------------- Anders Holmbech Nielsen | Tlf: (+45) 70 22 56 00 Software Engineer | Fax: (+45) 70 22 57 00 Integrator Uniware A/S | http:/www.integrator.dk

Validating page entry help
by Stuart Foster 22 Jun '00

22 Jun '00

I was wondering what the best way to validate a users input on a page. Currently I submit a page to an interim page that checks for certain values using dtml-if's and dtml-unless'. If everything is fine I go on to the next page. If something is missing I need to go back, I haven't figured out how to do this part. If I use <META HTTP-EQUIV="refresh" content=5;URL=<dtml-var "REQUEST['HTTP_REFERER']">> all the input is lost from the form. So my questions are: 1. What is the best way to do page validation before it is submited. 2. If the way I am doing it seems to be an ok way, how do I go BACK with out losing everything (equivalent of pressing the back button) Stuart Foster MediServe Information Systems > http://www.mediserve.com >

Zope security alert and 2.1.7 update [*important*]
by Brian Lloyd 22 Jun '00

22 Jun '00

Hello all, We have recently become aware of an important security issue that affects all released Zope versions including the recent 2.2 beta 1 release. The issue involves an inadequately protected method in one of the base classes in the DocumentTemplate package that could allow the contents of DTMLDocuments or DTMLMethods to be changed remotely or through DTML code without forcing proper user authorization. A Zope 2.1.7 release has been made that resolves this issue for Zope 2.1.x users. This release is available from Zope.org: http://www.zope.org/Products/Zope/2.1.7/ A patch is also available if it is not feasible to update your Zope installation at this time (the patch is based on 2.1.6): http://www.zope.org/Products/Zope/2.1.7/DT_String.diff If you are evaluating any of the recent 2.2 alpha or beta releases, you should apply the patch noted above if your site is accessible by untrusted clients. A forthcoming 2.2 beta 2 release will contain the fix for this issue. While we know of no instances of this issue being used to exploit a site, we *highly* recommend that any Zope site that is accessible by untrusted clients take the appropriate mitigation steps immediately.
