[Zope-dev] Possible 'bad' with Client.py and urllib
Hi, Both urllib and Client.py can be used to get stuff from other sites via HTTP and do useful stuff with it, right? Well, I was doing this and I think I've found what could be a 'real bad problem'. It appears that both of the above block while getting stuff from the remote site. Worse than that, they don't only block their current thread, they seem to block _all_ the Zope threads. The reason I say that is I ended up in a situation where I was using Client.py to get something from the Zope server on which Client.py was running. Because of the above, it effectively blocked the whole Zope server until the Client.py bit timed out. Does any of this make any sense to anyone? Is there a thread-safe equivalent of Client.py and/or urllib.open? Kindof related, is there any way to set the HTTP timeout when getting stuff using either approach? cheers for any help, Chris ___ 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 )

I want to fiddle with this so an image put via WebDAV is a myImage object (for example) rather than an Image Cheers. -- Andy McKay. ___ 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 )

We have had that behaviour when we used an old DCOracle to connect to an Oracle 8.1.6 server: The oracle client library cause a memory corruption that brought our Zope down about every 5 to 10 minutes. Our problem disappears after we installed a newer DCOracle.

[Zope-dev] Storing part of an object on the file system
Ok whack idea #34... Well sort of, the idea was sparked by ExtFile (yes its all his fault honest). We want to have files on the file system for many reasons which I won't go into now, just take it for granted. But we also want some of the objects information to be in the standard data.fs, so we can catalog it use acquisition provide a simple interface to it and so on. So far you are saying thats ExtFile and you are right. But we want to extend it to any object anywhere, instead of storing the data attribute in the object and pickling it in the ZODB I want to be able to store the data attribute on the file system. This gives us loads of advantages we also thought this would be extremely useful to other people. We've bounced around ideas on how to do this and here the only two so far: -we could overload the data attribute with a class that on Pickling into the ZODB instead writes it on to the filesystem... -we could in the ZODB put a hack to say if pickling something with so and so attribute do this instead... I feel like this something I should just not be doing, but it would be great if I could get it work... -- Andy McKay. ___ 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 )

[Zope-dev] Greedy except clauses
I've run into several greedy except: clauses now, and have submitted patches to make them a little less greedy. Out of curiosity, I searched the Zope source for "unfiltered" except: clauses... % grep -rl "except:$" . |wc -l 102 ... erk Just picking some of the results of that search at random, I noticed places where underlying exceptions could be eaten where I'm sure they'd be better propogated up... BTW, I did that little search above when I had a stupid (read: cut'n'paste :) bit of code that recursed on itself. Python generates a RuntimeError when that happens. I didn't get the RuntimeError. Zope simply quit on me with no error message. I have no idea where the RuntimeError is being caught, but I would strongly argue that it shouldn't be! I'm willing to have a go at cleaning some of those except: clauses up, but I can't possibly do 102 of them (I have a product dealine coming up :) Richard -- Richard Jones [EMAIL PROTECTED] Senior Software Developer, Bizar Software (www.bizarsoftware.com.au) ___ 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] Storing part of an object on the file system
I would like to throw in something I've been thinking about for the last week or so. I would like to use Tux as the front-end of my website. For info on Tux. ftp://ftp.redhat.com/pub/redhat/tux/tux-2.0/ http://www.redhat.com/products/software/ecommerce/tux/ From the website: """TUX is a kernel-based, threaded, extremely high performance HTTP server. It is able to efficiently and safely serve both static and dynamic data. TUX moves the HTTP protocol stack to the kernel, and can handle requests for data with both kernel-space and user-space modules.""" It has been reported to do over 10,000 requests per second on a static html file of 1666 bytes. It did over 1,000 rps doing a cgi program, opening and closing the cgi app each request. I read this from Linux Weekly News which got it off of the Linux Kernel Mailing List. From what I understand Tux 1.0 holds the SpecWeb record. Tux 2.0 is faster. :) I think it would be interesting to see Zope fronted by Tux. If there were a Tux cache manager for Zope that would be awesome. I've been trying to figure out how to maximize what Tux can serve and what Zope can manage. An optimal mix between the two could create a very manageable and fast website. Tux primarily caches what is available on the file system. It can serve multiple files (objects) sequentially as instructed by the "user module" as part of a single client request, thus assembling the request to send to the client. I'm butchering the explanation, but any ways, it's fast. Unfortunately, I am still working on understanding Tux and how to best use it. I don't program C and so reading the sample code hasn't sunk in yet. I don't know how to integrate it with Zope. It would be great it one of the brilliant people on this list could figure this out. :) :) :) Just thinking out loud. Jimmie Houchin Andy McKay wrote: Ok whack idea #34...

If so, you could easily enough run a daily job like: find . -name '*.py' -print | xargs grep -n 'except:' | cut -d: -f1,2 to get the list of them from the source, and put the root of a viewcvs URL on it.

Re: [Zope-dev] Greedy except clauses
ooo. Richard didn't do it right - there's actually over _600_ bareword except: clauses in the current zope-2_3-branch A quick breakdown of some of the biggies: 71 in OFS/ 61 in ZODB/ 56 in ZServer/ 53 in ZGadflyDA 50 or so in what seems to be test scripts or modules (probably ok) 42 in ZPublisher/ 42 in DocumentTemplate/ 40 in App/ 38 in AccessControl/ 32 in Shared/DC/ZRDB/ 24 in ZCatalog 15 in webdav/ 15 in DateTime/ 13 in PythonScripts 12 in utilities/ or the install scripts 11 in OFSP/ Now, it's obvious that not all of these are bad - some are probably fine - but there's also many that are _not_ good. The one in MailHost.py does eat exceptions. I'm sure there are others. I've done a quickie hack script that runs over the source and produces a list of matches to lines in the file, and links to a lightly patched viewcvs so that you can jump straight to the lines. It seems like it would be reasonably easy to make this a bit more sophisticated to include things like the nesting 'def' and 'class' method. This, to me, seems like a pretty nice community type task - people could take one of them off the list of unchecked ones, and have a look through the code... no?

Re: [Zope-dev] Storing part of an object on the file system
I had a similar problem. I'm using ExtImage, but I need some extensions for it.
Because I using a RDMBS (currently MySQL) I wanted to have all the meta data
in my RDMBS.
For all my objects there is normally a 'InsertMethod'. This can be a ZSQL
method (if just MySQL is involved) or it can be a DTML method.
For inserting an Picture object I have two steps in my DMTL InsertMethod:
dtml-let
ret="manage_addProduct['ExtFile'].manage_addExtImage(title=_['PICTURE.TITLE'],
descr=_['PICTURE.DESCR'],
file=_['PICTURE.FILE'],
content_type='',
create_prev=create_prev,
maxx=maxx,
maxy=maxy,
ratio=ratio,
permission_check=permission_check,
REQUEST=REQUEST)"
dtml-if expr="_.string.find(ret,'success') != -1"
dtml-call
"REQUEST.set('PICTURE.PIC_NAME_ID',_.string.strip(getImageName(message=ret)))"
dtml-call "REQUEST.set('PICTURE.TITLE',_['PICTURE.TITLE'])"
dtml-call PictureInsertMethod // this is a ZSQL Method
dtml-call "RESPONSE.redirect('SearchResult?GALERIE.GALERIE_ID='+
_.str(_['GALERIE.GALERIE_ID']))"
dtml-else
dtml-var ret
/dtml-if
/dtml-let
Okay, it's not transaction safe for now, but that's is acceptable in my
environment. Of course there can be some improvements.
Hint: I extended ExtImage for dynamic resizing. A preview is computed on the
fly. Maybe there is a need for this. I will send the extension to Gregor.

Re: [Zope-dev] Stop words/vocabulary
Hello Dieter, I have now a german stop word list and would like to apply it for my current ZCatalog 'NewsCatalog'. But how? Or should I copy my list to the source (no good idea)? Thanks. On Thu, 08 Feb 2001, Dieter Maurer wrote: Arno Gross writes: Can I apply stop words in a ZCatalog? You can: ZCatalog's "Lexicon"'s (-- SearchSupport.Lexicon.Lexicon) have a method "set_stop_syn" to provide a mapping for synonyms and stop word. I think, the source documentation is wrong: It says, the mapping would map words to a list of synonyms. When I looked at the code in "SearchSupport/Splitter.c", I had the impression that a map from a word to a single replacement is expected. A "None" replacement signifies a stop word, other replacements can be used for stemming or synomyms. Are there stop words for german available? If not I would try to compose a stop word list for german and publish it. Good!
