You can also create an external python script to call private methods. -----Original Message----- From: zope-cmf-admin(a)zope.org [mailto:zope-cmf-admin@zope.org]On Behalf Of John_Knutson(a)candle.com Sent: Friday, August 09, 2002 12:53 PM To: Tres Seaver Cc: zope-cmf(a)zope.org Subject: Re: [Zope-CMF] Access to other members properties Tres, That was one of the approaches that I tried. However, since that methjod is private, I needed to create a protected method in Membership to invoke it and when I called that, I got an Attribute Error from somewhere. Maybe I should just create something based on searchMemberDataContents without any security at all. I'll try that and see how it goes.

CMFCore.Membershiptool.MembershipTool has a utility method which might give you a good start: security.declarePrivate( 'searchMemberDataContents' ) def searchMemberDataContents( self, search_param, search_term ): """ Search members """ res = [] if search_param == 'username': search_param = 'id' for user_wrapper in self._members.values(): searched = getattr( user_wrapper, search_param, None ) if searched is not None and string.find( searched, search_term ) != -1: res.append( { 'username' : getattr( user_wrapper, 'id' ) , 'email' : getattr( user_wrapper, 'email', '' ) } ) return res While this is hardly as general as it could be, it does sketch out the access method for searching memberdata.

startup script for red hat linux?
by Mark McEahern 12 Aug '02

12 Aug '02

Anybody have an /etc/init.d/ startup script for Zope for Red Hat Linux? I did a quick search on google and found a Debian one. I'll probably take a peek at that and see if I can make it work. Thanks, // mark -

Temp Folder Magic
by Terry Hancock 12 Aug '02

12 Aug '02

Hi all, I'm finally revisiting the nasty part of my code that periodically hoses itself and fails to deliver resized images. ;-D I need to implement a cache of image objects in Zope (i.e. not in front of Zope), and it was suggested to me that the best way might be to use "Temporary Folders" in Zope 2.5.1. Anyway, I now see that Temporary Folder is a bit more magical than most Zope objects (not too surprizing I suppose). Anyway, what I'm trying to do is inherit from both Image and Temporary Folder and create the resized images in the object (supposing that they will then be stored temporarily). Perhaps this is naive, but it was my first guess as to the most logical way to do this. What I actually have looks like this: class VarImage(OFS.Image.Image, MountedTemporaryFolder) : """ Variable-size image object for Zope. """ #[... lots of hopefully irrelevant detail omitted ...] def _read_url_cmd(self, keystr): # Actual command recognition omitted for brevity, # but for example's sake: if keystr=='s100': return (100, 100) else return None def __getattr__(self, keystr): dimensions = self._read_url_cmd(keystr) if dimensions == None: # Unrecognized URL requested, pass through: # raise ValueError, 'Unrecognized VarImage scaling command.' try: return MountedTemporaryFolder.__getattr__(self, keystr) except: return OFS.Image.Image.__getattr__(self, keystr) else: nx, ny = dimensions # This part is messy, because I'm testing, eventually it # will do a bit more to try to get a cache hit instead of # creating the image everytime: threading.Lock() img_file, img_type = img_resize(StringIO(self.data), self.content_type, nx, ny) img = OFS.Image.Image(keystr, title='', file=img_file, content_type=img_type) self._setObject(keystr, img) # ^^^^^^-- This chokes #self.manage_addProduct['OFSP'].manage_addImage(keystr, '', # file=img_file, content_type=img_type) # ^^^^^^-- So does this when you uncomment it threading.Unlock() # Okay, now throw all that away and return self anyway. # just for debugging of course -- this is so I'm not debugging # the actual resizing code. return self Looking in Products/TemporaryFolder.py makes me think I'm being naive, though. I note that the meta_type for MountedTemporaryFolder says it's "Broken Temporary Folder". So where does "Temporary Folder" come from? It's here in the __init__.py: def initialize(context): import TemporaryFolder context.registerClass( TemporaryFolder.MountedTemporaryFolder, permission=TemporaryFolder.ADD_TEMPORARY_FOLDER_PERM, icon='www/tempfolder.gif', meta_type='Temporary Folder', constructors=(TemporaryFolder.constructTemporaryFolderForm, TemporaryFolder.constructTemporaryFolder) ) (constructTemporaryFolder doesn't appear to be particularly different from the more common "manage_add" function, except for the name, BTW). This appears to be doing something clever, but I don't get it. I can't figure out when and how the Temporary Folder acquires Folder-like behavior. Questions: 1. *Can* I inherit from Temporary Folder as desired, and if so, will it act as a Temporary Folder? 2. If so, how? Which object do I inherit from, and/or do I have to do anything special to make it non-broken, since it apparently starts out broken? Any clarifications much appreciated, thank you!

Re: [Zope] FTP from Zope
by Dennis Allison 12 Aug '02

12 Aug '02

Thanks, Dieter. The FTP script basically walks the source folder tree on the Zope side and issues a 'mget *' instruction in each folder, then either issues a 'cd name' to visit an enclosed folder or a 'cdup' to return to a previous folder. There is only one FTP instance at work (Zope at the source end, wu-ftp at the sink end). I would have thought that FTP would be dumb and not fire off independent copy processes for each transfer. I'll try it again and take a look using lsof.

rewrite, VHM, and base href problem
by Tim Wilson 12 Aug '02

12 Aug '02

Hi everyone, I'm finally getting around to working on problem that's been bothering me for a while. I'd like to use a Virtual Host Monster (VHM) and Apache's mod_rewrite to redict certain URLs to subdirectories of my Zope site. For example: http://isd197.org/mendota/ and http://mendota.isd197.org/ The first one works perfectly. The second, however, works except for the graphic at the top of the page. Viewing the source of the page reveals the following: CTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> <HTML> <HEAD> <base href="http://www.isd197.org/" /> Notice that the base is set to the root of my Zope. As a result, the image that is supposed to appear at the top of this page is not found. The relevant section of httpd.conf looks like <VirtualHost 206.131.108.110> ServerName mendota.isd197.org DocumentRoot /var/www/district RewriteEngine On RewriteLog "/var/log/apache/rewrite_log" RewriteLogLevel 3 RewriteRule ^/(.*) http://127.0.0.1:8080/VirtualHostBase/http/mendota.isd197.org:80/mendota/Vi… [P] </VirtualHost> Apache's rewrite log shows this: 134.84.184.23 - - [12/Aug/2002:10:38:29 -0500] [mendota.isd197.org/sid#80a9954][rid#8095974/initial] (2) init rewrite engine with requested uri / 134.84.184.23 - - [12/Aug/2002:10:38:29 -0500] [mendota.isd197.org/sid#80a9954][rid#8095974/initial] (3) applying pattern '^/(.*)' to uri '/' 134.84.184.23 - - [12/Aug/2002:10:38:29 -0500] [mendota.isd197.org/sid#80a9954][rid#8095974/initial] (2) rewrite / -> http://lists.isd197.org:8080/VirtualHostBase/http/mendota.isd197.org:80/men… 134.84.184.23 - - [12/Aug/2002:10:38:29 -0500] [mendota.isd197.org/sid#80a9954][rid#8095974/initial] (2) forcing proxy-throughput with http://lists.isd197.org:8080/VirtualHostBase/http/mendota.isd197.org:80/men… 134.84.184.23 - - [12/Aug/2002:10:38:29 -0500] [mendota.isd197.org/sid#80a9954][rid#8095974/initial] (1) go-ahead with proxy request proxy:http://lists.isd197.org:8080/VirtualHostBase/http/mendota.isd197.org:80/mendota/VirtualHostRoot/ [OK] Can anyone offer a suggestion? -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.org | http://www.zope.com W.

FTP from Zope
by Dennis Allison 12 Aug '02

12 Aug '02

I wrote an External Method which generates an FTP script to download as source one of my sites. When I pass it to the FTP system it happily logs into Zope and starts the downloads, building the directory tree on the way. Part of the way through it dies on a "too many files" error. And a look at the transaction log says there were lots and lots of file errors. I did not attept to do much of a handshake -- I just stream the commands into the ftp program ftp -m <commands >>log The commands manage the tree traversal and actions on both the source and the destination and follow the general pattern of move to directory at the source create directory at destination (the local machine) mget * move to any subdirrectory (and repeat recursively) Any idea why it bombs? workaround? -dra
