Design around conflict errors
by Jeff Youel 10 Oct '03

10 Oct '03

I've created an object to record some information (datetime, url, username) for each file downloaded from the site for later searching (CMF 1.3.1, Zope 2.6.1). To do this, I have a BTreeFolder with a private ZCatalog and put an new instance of a DownloadRecord object (my own object that just has string members holding the fields to be queried later) into the folder when the file is requested. I'm running into conflict errors; I think because the download record object is added to a single folder so concurrent downloads on different threads are competing trying to modified the folder. Because the downloads will take a while (they're 1-5 MB), the transaction is not committed until the download is complete. With a large download it seems that window for conflicts is large. I've been googling and reading about conflict errors but haven't found a solution yet. I've tried committing the a sub-transaction but that didn't help. I'm thinking of committing the default transaction before sending the file, but I'm not sure of the implications of doing that. Any ideas? Thanks, Jeff

VirtualHostMonster and FTP
by Luke Duff 10 Oct '03

10 Oct '03

I'm able to add mappings in VirtualHostMonster to point *.mysite.com to /Sites/MySite successfully as far as HTTP goes. I'm wondering if there's any way to get it working with FTP. I still have to ftp to mysite.com and change the dir to /Sites/MySite. My mappings are like this: *.mysite.com/Sites/MySite I'm not running zope behind Apache or IIS, just the straight zope server. Thanks, Luke Duff

URL redirection, maintaining arbitrary path?
by Ian Beatty 10 Oct '03

10 Oct '03

Greetings. I'm in the process of porting a website over to Zope/Plone, and find it necessary to do some reorganization of my site's URL structure. In order to break as few old links as possible, I'd like to put in some redirects. I've found information on how to redirect one particular URL, but what I'd like to do is this kind of thing: have *any* request of the form http://my.server.com/x/a/b/... get redirected to http://my.server.com/x/newPiece/a/b/c where the path that comes after "x/" in the original URL (if anything) is preserved at the end of the "new" URL. In other words, I'm mapping an entire tree of my site to a new location. Is this possible? Any suggestions?

Help: terrible problem
by DTE webmaster 10 Oct '03

10 Oct '03

Hi, I had Zope instaled in a machine running SuSE 8.1 Zope 2.6.1 was compiled using Python 2.1 Now, we bought a new server and installed RedHat 9 I've made a tarball from the old server and uncompressed it in the new one. If i run Zope with Python 2.2.2 (bundled with RedHat) i've got two warnings and Zope starts. But the access to the site holds on until timeout. I 've compiled Python 2.1 and i got an error saying there was no _socket.so I've copied it from the old to the new server and then it complained about not finding libssl.so.0.9.6 I've resolved the issue with a symbolic link. Same thing for libcrypto. Well, this time Zope starts without errors, but there again is so slow unitil timeout. What is going on ? Please help. Thank you in advance for your time and patience. Warm regards, Mário Gamito

About catalog and folder privacy...
by Patrick Gelin 10 Oct '03

10 Oct '03

Hi, I'm looking to modify the catalog (or change the catalog with an other product) which take into account the folder's privacy. For example a public object inside a private folder must not be displayed to a member or anonymous user! My goal is to create sub-workspaces inside my Plone site and I think this is the only way... Thanks.

Any reason why you shouldn't just use <dtml-var AUTHENTICATED_USER> as a parameter to your SQL query? just curious... _______________________________________________ Zope maillist - Zope(a)zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

can't use filter to check permission?
by Milos Prudek 09 Oct '03

09 Oct '03

The following Python script, when invoked in a folder, should list all ZPT methods that the current user can "View. from AccessControl import getSecurityManager checkPermission = getSecurityManager().checkPermission def okPermissionView(item): allowed= 0 try: allowed= checkPermission('View', item) except: pass return allowed objects = context.objectValues('Page Template') objects = filter(okPermissionView,objects) for item in objects: print item.getId() return printed It works for Managers (who can view anything), but it fails with Unauthorized at the "objects = filter(..." line. When I unfold the source so that filter is not used, it works without a hitch. See the "unfolded" source below: from AccessControl import getSecurityManager checkPermission = getSecurityManager().checkPermission objects = context.objectValues('Page Template') for item in objects: allowed= 0 try: allowed= checkPermission('View', item) except: pass if allowed: print item.getId() return printed Does anybody know what's going on here??? -- Milos Prudek _________________ Most websites are confused chintzy gaudy conflicting tacky unpleasant... unusable.

Help: Suppress Virtual Host Monster...
by Tiller, Michael (M.M.) 09 Oct '03

09 Oct '03

I've had problems in the past with access rules and site roots and I know how to suppress those. But, I wasn't really able to find any information on how to disable a VHM. I cannot just change the host name because there is a "proxy" in the way that remaps the hostname. Is there a way that I can suppress VHM in the URL itself. I tried something like: http://my.testsite.com/_vh_manage thinking (from the VHM documentation) that this might somehow get me to the management screen at the root. Sadly, it didn't. Any suggestions?!? -- Mike
