Zope + Apache + mod_proxy + SiteRoot = some links not proxied?
by Alain Fauconnet 12 Apr '06

12 Apr '06

Hello readers, I've spent quite some time looking around for the "right" procedure to integrate Zope and Apache. I use mod_proxy as described in a number of places, especially: http://www.zope.org/Members/anser/apache_zserver I've followed the instructions step by step and it "mostly" works, meaning that *some* links do not work: - the "... folder at /..." link at the top of the main frame in ZMI - the top-right menu (quick start, prefs, logout) in ZMI - the ZMI link in the home (quick start) page - ... These links do not get rewritten to get "/zope" prepended to the local path part, so they give an error 404. All other links work, though, so I think that my setup is "almost" right. Am I missing something? I have created the SiteRoot object in the root (/) folder. Is this correct? Base is "http://my-server.my-domain.com/zope" Path is "/" To somewhat work around this problem, I have had to add a bunch of extra ProxyPass statements in Apache's configuration, like: ProxyPass /manage_page_style.css http://my-server.my-domain.com:8080/manage_page_style.css ProxyPass /manage_workspace http://my-server.my-domain.com:8080/manage_workspace ProxyPass /manage_zmi_logout http://my-server.my-domain.com:8080/manage_zmi_logout ProxyPass /manage_zmi_prefs http://my-server.my-domain.com:8080/manage_zmi_prefs ProxyPass /zope_quick_start http://my-server.my-domain.com:8080/zope_quick_start ProxyPass /manage http://my-server.my-domain.com:8080/manage ProxyPass /HelpSys http://my-server.my-domain.com:8080/HelpSys ProxyPass /Examples http://my-server.my-domain.com:8080/Examples ProxyPass /manage_importObject http://my-server.my-domain.com:8080/manage_importObject This is probably not the right approach, but I can't find what is wrong in my setup.

The only change in the configuration was that I installed ZMySQL DA any pointers? christian

Problems Executing pdftk from within zope.
by Jerry Westrick 11 Apr '06

11 Apr '06

Hello Zopistas... I trying to modify pdf files from within zope. I use the following command: '/usr/bin/pdftk /t/in.pdf attach_files /t/a1.pdf /t/a2.pdf output /t/out.pdf' When I execute it as root it works... When executed from within zope, (this i've done via external command that executes os.system(...)) A task is started to executed it, but the task hangs. Even with set the setuid bit on /usr/bin/pdftk, making the zope spawned task run as root the command just hangs.... (I've confirmed that the task is actually running as root!) I'm sure I've forgoten something silly, but after bashing it around for several hours I just can't figure out why it hangs Any suggestions at what the problem could be are welcome 8-) Jerry P.S. Here my Control panel info, incase it's relevant....

Is ExtFile right for me?
by Kirk Strauser 11 Apr '06

11 Apr '06

My Zope site generates many reports in PDF format, and stores them in a folder that's only accessible to customers via a password-protected form. I currently store each report's password as a property of its File object. My problem is that I'm creating several hundred megabyte-sized file objects in my ZODB each day, and even though I expire them after five days the performance hit when storing and fetching the files is painful. I think, then, that I should be looking at an external filesystem store. LocalFS looks very nice, but it doesn't seem to support properties (which I currently need). ExtFile looks very nice and does support properties, and that's the way I'm heading. Does that seem reasonable given my usage? Also, I'm currently inserting the file uploads into a folder named "files" (ain't I creative?) with this method call: context.files.manage_addFile(id=filename, file=filecontents, content_type=filetype) I tried what I thought would be the ExtFile equivalent: context.files.manage_addProduct['ExtFile'].manage_addExtFile(id=filename, file=filecontents, content_type=filetype) but that only dumps the contents of the file to the client and doesn't actually store that data. Clients see a long page of gibberish like: Shipment Search | View Selected Images %PDF-1.2 %âãÏÓ 1 0 obj << /Type /Catalog /Pages 3 0 R >> endobj 2 0 obj << /CreationDate (D:20060410110742) /ModDate (D:20060410110742) /Producer (libtiff / tiff2pdf - 20060313 / d) >> endobj 3 0 obj << /Type /Pages /Kids [ 4 0 R 9 0 R ] /Count 2 >> endobj 4 0 obj << /Type /Page /Parent 3 0 R /MediaBox [0.0000 0.0000 608.2560 792.0000] /Contents 5 0 R /Resources << /XObject << /Im1 7 0 R >> /ProcSet [ /ImageB ] >> >> endobj 5 0 obj << /Length 6 0 R >> stream q 608.2560 0.0000 0.0000 792.0000 0.0000 0.0000 cm /Im1 Do Q endstream endobj 6 0 obj 62 endobj 7 0 obj << /Length 8 0 R /Type /XObject /Subtype In other words, the normal page header, plus the raw data. I'm not sure why that's happening. -- Kirk Strauser The Day Companies

[Ann] Incremental filtering: a new way for catalog query optimization
by Dieter Maurer 09 Apr '06

09 Apr '06

Catalog searches are often slow. IncrementalSearch[2] can lead to drastic gains in query time. However, there is a large class of queries that cannot be significantly sped up: queries that contain huge Or subqueries involving bushy indexes, usually resulting from a time based subquery checking effectiveness and expiration (or other similar use cases) The newest versions of the companions "AdvancedQuery", "ManagableIndex" and "IncrementalSearch[2]" support incremental filtering to execute most such queries efficiently. With incremental filtering, the index is not use in the usual way. Instead, the remaining query parts determine a set of document candidates with is then filtered by the filtering subqueries, dropping documents not matched by these subqueries. Lets look at an example: Suppose you search for news containing 'AdvancedQuery' which are effective and not expired. The standard query would look like Eq('portal_type','News') & Eq('SearchableText', 'AdvancedQuery') & Le('effective', now) & Ge('expires', now) Internally, the "Le('effective', now)" subquery is expanded into "Or(*[Eq('effective', t) for t in 'effective' and t<=now]) which usually is huge. The "Ge" subquery is similarly expanded. The filtering query has the form Eq('portal_type','News') & Eq('SearchableText', 'AdvancedQuery') & Ge('expires', now, filter=True) & Le('effective', now, filter=True) When this query is executed, "Eq('portal_type','News') & Eq('SearchableText', 'AdvancedQuery')" determines a set of candidate objects. From this (probably small) set, objects not satisfying "expires >= now" and (then) "effective <= now" are filtered out. This way, we avoid the construction of huge Or subqueries. Of course, filtering is only efficient in some circumstances: usually, when the other query parts already garantee a small set of candidates and the filtering can avoid the construction of large intermediaries. Otherwise, filtering may not improve the query speed but increase it (maybe even drastically). Incremental filtering is a powerful optimazation tool, which need careful usage... You need the complete bundle ("AdvancedQuery", "IncrementalSearch[2]" and "ManagableIndex") when you want to use incremental filtering.

filtering results
by gf 08 Apr '06

08 Apr '06

Hi, I am a Zope newbie. I apologize if the terminology I use below is not correct, but I hope that you get the gist of what I am about to ask. I would like to be able to 'filter' results before returning them to the user. In other words, if a user requests a given object, it is passed through a filter before being passed on to him or her. As a simple example, I may want to tidy the html before the user sees it, or eliminate or add certain tags or words. I have put together a simple 'html tidy' external method that takes raw html and produces a tidied version, but I don't know how I can apply it. Thank you for any comments, suggestions, or simple examples you may be able to provide. Best Regards, gyro
