[Zope-dev] AttributeProvider and type information
I just want to ask a couple quick questions... First, when using the AttributeProvider class you are pretty much required to subclass it to add methods for altering the values of the attributes. Basically I want to be sure I'm not missing something criticle as there don't seem to be any methods on the default dataskin class for this (as there are for propertysheets)... and it seems like there should be. Related to this is dealing with typing information like PropertySheets used (via the _properties attribute). Wouldn't make sense to keep the AttributeProvider consistent with this... instead of the simple Attributes list? Seems like the type information and other meta information would as useful for handling attributes on the dataskin as for propertysheets. -- John Eikenberry [[EMAIL PROTECTED] - http://zhar.net] __ "A society that will trade a little liberty for a little order will deserve neither and lose both." --B.

[Zope-dev] Xron fragility

Steve, I am also interested in scheduling... though I haven't looked closely at Xron. The Xron product seems rather "fragile" in use. That is, if things go wrong when an Xron DTML Method is triggered, that method doesn't get rescheduled. Does Xron take an optimistic approach to repeating jobs?

Then again, as all the work happens inside a ZODB transaction, it doesn't matter when the reschedule happens. What does the Dispatcher thread do? Does it fire off worker threads? Xron has a single dispatcher thread. This thread knows how long to sleep for until the next job needs to run. It uses Client.py to run a job. Jobs are Xron DTML Methods. They have a "trigger" method that gets called through the web from localhost, by the Dispatcher thread.

What are other threads in Xron doing while the Dispatcher thread is hosed? What are the other threads? There are no other threads in Xron. Xron creates a single thread to do all event dispatching. The work is done in Zope ZODB threads (or whatever the correct terminology is). The dispatcher thread communicates with a ZODB thread by using Client to make a web request. Xron usually makes requests as the anonymous user. However, I've patched my Xron to make requests as XronUser by hardcoding (!) the username and password for that in the RPC.py module of Xron. Then, I've manually created a XronUser user in my root user folder. I give XronUser the local roles needed to run methods I want to be scheduled via Xron. This is not the ideal way to make Xron use authentication. I posted a proposed design for that to zope-dev in August. http://lists.zope.org/pipermail/zope-dev/2000-August/006548.html http://lists.zope.org/pipermail/zope-dev/2000-August/006549.html http://lists.zope.org/pipermail/zope-dev/2000-August/006550.html -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Re: [Zope-dev] Xron fragility
Do you think this is this any more effective than having a producer thread do a lookup every minute to see what jobs are current, after which it should put the current jobs in a queue? E.g., as the "run" method of a separate producer thread: the same problem applies, a solution might be a timer and a signal handler to catch a signal event when a new job is entered into the system. events could be managed as some sort of collection of linked lists (or whatever ds). I think this problem is solved by: - polling for "current" events every 60 seconds *exactly on the 0th second of the minute* (this ensures that stopping and starting the scheduler won't accidently cause a "current" repeating event to fire twice). - allowing one-time events (which are most likely to need to be executed immediately) to be "current" for the minute implied by the event's timestamp as well as the minute just before that one. This ensures that an event that has a timestamp that was "current" when entered, but has subsequently been passed due to event polling overhead will be executed (even if it is entered at hh:mm:59.999 or similar). It also assumes that the scheduling poller will never take more than 60 seconds to poll all events, which is a fairly safe assumption. - the executor of the event is required to invalidate one-time events once they've been executed (or before they're executed) so they don't get fired twice. I don't believe there is any need for a signal handler or anything of the sort, the problem seems to just require careful synchronization. i played around with this in a monitor thread and you just can't achieve the proper semantics to execute an arbitray zope method. you have to recreate the request, response as well as have all the required support modules (DTML, tracebacks, etc) to successfully call a method, you are in essence reduplicating the publishing machinery. i tried to think of a way to get around this but i came up short. you can still access variables and simple methods. This would need to be thought through... the same problem exists for unit testing. :-( I see... would it be naive if I were to say that I think that a scheduler should fire off threads of its own and not rely on an external facility to run the jobs? the dispatcher thread itself has a connection to the ZODB, its using client as RPC to invoke the methods on Publishing threads. Since there is a hardcoded limit to ZODB connections firing off more connections does not seem like a good idea. AFAIK, threads will block if they can't get a DB connection. What risks does that imply?

Maybe, you can start from these descriptions. The Interfaces Wiki is actually where all the API documention did come from. Are there inconsistencies? It might also not be optimal wrt. maintainability that the modules, their classes and their methods with the respective docstrings have been recreated just for API documentation purposes. Probably, it would be preferable to use the docstrings and the method prototypes from the source directly. You might still want to control with methods are described in the API and in which order. Personally, I would control this, too, inside the source documentation (a la javadoc), but I can imagine that an external configuration might be advantageous. Yes, there are pros and cons on both sides, and Amos, Jim and I had some long converstations about this very subject. We decided to go with seperate documentation instead of autogenerating it because: 1. An interface should be a contract, not just an artifact of the code. 2. Python, being without first class support for interfaces, has no clear way of spelling an interface of a class. 3. Jim is working on formal interface support for python and he's thinking hard about it, we definatly didn't want to think hard about it and then turn out we came up with a bad answer, the existing API docs are just that, docs, not interfaces.

[Zope] Programmatically: zclasses and images
Hallo, I've got two problems cutting my nerves: The site-structure is organized in a way that zclasses can be added programmatically(the user decides by clicking on a tree-list where to add the classes) The 1. problem is that I can't manage to pass the URL of the selected object to add the zclass in the requested place. Therefore I'm not using one script for adding the instances, but every zclass is holding the constructormethod(you're clicking on the tree and the selected zclass is responding with the addFormular and later with the addConstructor). This way is working.I'm not very happy about it because every zclass is created with methods that I think can be avoided. My biggest problem is that I can't manage to add images in the new zclass. That's the script: dtml- with "manage_addProduct['Zzzz']" dtml-call "ZZZsite_add(_.None, _, NoRedir=1)" dtml-call "manage_addImage(pictureName,picture)" /dtml-with This is a zclassMethod and the formMethod(also inside the zclass)passes the 'picture' and 'picturename' variables!

RE: [Zope] Re: Upload just file headers?
Hmm, well you certainly can't do it at the browser side. A well-formed HTTP header should contain a content-length attribute which you can examine. However, deciding whether to accept the file or not would I imagine not be possible inside zope since the whole POST operation is handled by ZServer, so you probably have to write a cgi script to do it. For example, if you wanted to stick with python, you could use the cgi module. You'd examine the header, and if you were happy, you could pass on the data in a new POST to zope. If you were unhappy, you could return a value from the cgi. This is all off the top of my head, and I'm sure there must be a nicer way of doing it than that. It's not nice having it all outside zope. but it should be a start, at least. seb -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Paul Winkler Sent: 11 October 2000 06:52 To: Zope mailing list Subject: [Zope] Re: Upload just file headers?

I use Zope via Apache proxy, what causes some trouble (all remote IPs for Zope are equal to 127.0.0.1). As I finally installed mod_proxy_add_forward, I get original address in X-Forwarded-For header (REQUEST['HTTP_X_FORWARDED_FOR']). The question is: can I do something easy to automatically perform if(remote_ip = 127.0.0.1 and X-Forwarded-For exists) then set remote_ip = whatever is in X-Forwarded-For logic? In particular, I would like changed IP to be used by Zope access control and Zope log.

Re: [Zope] Re: Upload just file headers?
Paul, I'm sorry if I'm dropping context here, but I'm not sure what you mean when you say "headers of files". Do you just want to check the size of files before you put them in the ZODB? - Original Message - From: "Paul Winkler" [EMAIL PROTECTED] To: "Zope mailing list" [EMAIL PROTECTED] Sent: Wednesday, October 11, 2000 1:51 AM Subject: [Zope] Re: Upload just file headers? Still haven't found an answer, after 4 hours searching the egroups archive. Just to clarify: I need to read the headers of the files BEFORE I upload the entire file, because the files may be very large and I need to be able to give a warning if the file does not meet certain criteria. Example: a jpeg file of 500x400 pixels, approx. 200 kb when the application, to be used in an application that needs much higher resolution in order to look good. I want to avoid wasting 50 seconds or so uploading this file just to find out that it's no good. If I could upload the first bit of the file (1k should be plenty), I could open it with PIL and check the size attribute. (I've verified this by doing head --bytes 500 foo.jpeg test.jpeg and then opening test.jpeg in python - it works even though the file has been truncated.)

[Zope] Restart button corrupted data.fs.index file
After installing two new Products (ZCounter the first time,and FSCounter
the next time), I hit the Restart button in the Zope Control Panel. Zope
did not come up. I tried a manual stop/start. The start resulted in this
error message:

The data.fs.index file was then corrupt. If I renamed it, and tried
another start, Zope would start fine. I did this twice w/ the same
results.
I'm using Zope 2.2.2.

should also send it to a Zope mailing list -- since I'm not on Zope Dev
yet, I'm sending it here. I have a copy of the old index files if anyone
needs to see them.

[Zope] Zope Hotfix: ObjectManager subscripting
This hotfix addresses an important security issue that affects Zope versions up to and including Zope 2.2.2. The issue involves the fact that the 'subscript notation' that can be used to access items of ObjectManagers (Folders) did not correctly restrict return values to only actual sub items. This made it possible to access names that should be private from DTML (objects with names beginning with the underscore '_' character). This could allow DTML authors to see private implementation data structures and in certain cases possibly call methods that they shouldn't have access to from DTML. While we know of no instances of this issue being used to exploit a site, we recommend that any Zope 2.2.x site that allows DTML to be edited by untrusted users apply this Hotfix. http://www.zope.org/Products/Zope/Hotfix_2000-10-11/Hotfix_2000-10-11.tgz The hotfix will work for all versions of Zope 2.2.0 and higher. A future version of Zope will contain the fix for this issue, and you will be able to uninstall the hot fix after upgrading. ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Re: [Zope] Re: Upload just file headers?
Another way to look at it:

That would be useful, but I need more information than that.
I need to read some of the file's description of itself
that's commonly kept in a header at the beginning of a file.
For example, take a .gif or .jpeg file and throw away all
but the first (let's say) 1 kb of the file.
If you try to open this truncated file with an image editor
(gimp, photoshop, whatever) you'll have problems. But useful
information is still stored in that first part of the file,
as we can see using python and PIL.
Example, on linux:
head --bytes 1000 foo.gif foo_truncated.gif
python
...
import Image
test = Image.open('foo_truncated.gif', 'r')
test.size
(210, 210)
So in this case, we can find out that foo.gif is 210 x 210
pixels even if we only have access to the first 1 kb of the
12 kb file.
If the file in question is 1 MB or so, this trick becomes
really useful.
Suppose your web application needs an image about 1000 x
1000 pixels. You could warn the user if their image is too
small to look good, or so big it's a waste of their time.
So basically what I want to do is start uploading the file,
but stop quickly.
Now then, does anyone know how to do it?
Thanks again,

Re: [Zope] Re: Upload just file headers?
Here's an idea for you. I use some of the code below in my FileBase
product to receive uploads, although, I've added some "code" I think might
help you for grabbing just the header.
Although I'm not sure if the file descriptor that infile claims from the
form has already been loaded into either a StringIO or some other
"buffer" (i.e. already received in full from client), it's possible that
this is reading directly from the http stream coming from the client.
infilename = REQUEST.form['attached_file'].filename # Get filename
infile = REQUEST.form['attached_file'] # Get the file descriptor
myheader = infile.read(500)# Read up to 500 bytes
infile.close() # Close the stream
This should be in an external method or product.
I haven't tested whether or not this will only let the client upload the
first 500 bytes, it's very possible zope takes in the entire file, and
puts it into a buffer that is like a file descriptor (hence StringIO).

[Zope] Need preferred 'import' format for ReportLab Image module
Hi all, This is of interest to those people using the (excellent) PDF generator, ReportLab http://www.reportlab.com/ under Zope. As you may know, there is an import conflict with the 'Image' module from PIL and the built in Zope 'Image' module when using ReportLab. The snippet below is from the main ReportLab developer, Andy Robinson. If it's not too much trouble, that would be very useful for those of us using Zope (the number is growing all the time). We will try to do this. But which import format does Zope require? 'import Image' of 'import PIL.Image'? And is this some sort of packaged 'PIL-for-Zope'? If it was just PIL on your hard disk, you would have 100% control over the problem just by adding the right directory to your path. Sorry, I'm working all hours and don't have time to download and play with Zope this month. - Andy -- So, can anyone with a higher 'import' Zope Zen please give me a clue as to how to reply to Andy? In my own reportlab distribution I changed; import Image to from PIL import Image and that seemed ok, but I'd like a 'definitive' answer on this from some bods with Nirvana-level Zen BTW, If you're not a reportlab user (open source, free download), then you're missing out - this is terrific software...we have it connected to ZSQL methods and are churning out PDF documents *very* quickly. cheers, Tone ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

[Zope] Using ProxyPass and SiteRoot
Hi everyone, I've read the "Using Apache with ZServer (NOT Zope.cgi)" How-To and I find that my situation is different enough from the ones described that I'm not having any luck setting it up. I'd appreciate any suggestions on the following: My current Zope site is at http://www.isd197.k12.mn.us/ which uses Zope.cgi. There are a number of other static, non-Zope virtual hosts running on that same machine representing a number of our elementary schools. I've been developing a new Zope site on a separate machine at http://206.131.108.103:8080/ using just ZServer and I would like to use ProxyPass to pass a request for www.isd197.k12.mn.us through to this new site. Can someone suggest ProxyPass and SiteRoot settings that will make this work? -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.k12.mn.us/ | http://www.zope.org/ W.

Can someone suggest ProxyPass and SiteRoot settings that will make this work? -Tim Timothy, Without going into too much detail, you are going to want to set up a virtual host in apache for the hostname www.isd197.k12.mn.us, and inside that virtual host you will want to add your ProxyPass lines similar to my example: VirtualHost 63.193.78.22 ServerAdmin [EMAIL PROTECTED] DocumentRoot /home/knight/www/phunc/html ServerName www.phunc.com ErrorLog /home/knight/www/phunc/logs/error_log CustomLog /home/knight/www/phunc/logs/access_log combined ScriptAlias /cgi-bin/ "/home/knight/www/cgi-bin/" IfModule mod_rewrite.c RewriteEngine On RewriteLog "/home/knight/www/phunc/logs/rewrite_log" RewriteLogLevel 2 RewriteRule ^/cgi-bin/ - [L] RewriteRule ^/local/(.*) http://www.phunc.com/$1 [L] RewriteRule ^/(.*) http://www.phunc.com:8080/$1 [P] ProxyVia on /IfModule /VirtualHost Where I've used Rewrite, you will want to replace it with your ProxyPass lines. Keep in mind that _any_ requests for www.isd197.k12.mn.us will get passed to your zope site, and you will need to add "local" entries for directories you want to stay on the apache system for that FQDN. For the other non-Zope virtual hosts, just have them set up the same way they are most likely.

[Zope] How to use standard html headers and footers properly (was: Re: [Zope]Namespace problems...)Namespace problems...)
dtml-with pub> dtml-let titel="_.string.join(['This is the website of ', enterpriseName])"> dtml-var standard_html_header> /dtml-let> on your document, WILLwork fine. But I suggest recreating standard_html_header as a METHODand calling dtml-with pub> dtml-var standard..> /dtml-with> Since methods don't have properties, they will use calling object's properties. Read again. Do NOTuse DTMLdocuments for headers and footers. Use METHODS. Lars Heber wrote: Hi there, I've still got to build a bigger website. So I stored my headers and footers and many other things in root/pub. All the other documents are stored in root/Intra and below. I've got my standard_html_header, with which I can display user-defined titles which may also contain values of global properties. The user-defined title is being built in the document before the header is called, e. g. something like: dtml-with pub> dtml-let titel="_.string.join(['This is the website of ', enterpriseName])"> dtml-var standard_html_header> /dtml-let> In the standard_html_header method I'm checking whether there is a titel attribute or not. This works fine. But for general use I want to keep the possibility of displaying the title_or_id of the document when I don't introduce a user-defined title. This would be no problem if s_h_h wasn't situated in root/pub, so I have to call it within the dtml-with pub>. But doing this, pub is on the top of my namespace, so that calling title_or_id returns the title_or_id of the container of s_h_h, i. e. pub! How can I nevertheless access within the s_h_h to the title_or_id of my original document? Thanks.

[Zope] SybaseDA and ASA
Hey everyone, first, let me thank you for all the help you've provided. Every reply was fast, efficient and right to the point. Second: I've installed zope 2.2.2, and compiled sy_occ.so for SybaseDAagainst sybase-common-cantrememberversion.rpm from Sybase. (I assume it's the latest one). Loading python and importing sy_occ works perfectly. BUT, I can't create a SybaseDA SQLconnection object . Specifically, trying to create it sez connection failed. I've tried EVERYPOSSIBLE parameter combination on the creation form. None worked. By the way, I'm using Adaptive Server Anywhere for linux, 6.0.3. It is NOTASE. It is ASA. Does sy_occ work with ASA, or only with ASE? Any experiences? -- Manuel Amador (Rudd-O)
