Fwd: Seaside on Pharo-Kernel
by Pavel Krivanek 11 Aug '11

11 Aug '11

Hi, there's possible to load Seaside to the Pharo-Kernel. 1) Load PharoKernel-Gofer image from CI server (https://ci.lille.inria.fr/pharo/view/Pharo-Kernel/job/Pharo%20Kernel%20Gofe…) 2) run the image with seaside.st script as an argument. That will create about 4.1 MB image with basic Seaside packages and basic examples. 3) run the image with run.st script (note that starting of the server in the seaside.st script will hang, currently I have no idea why). 4) see if everything works at http://localhost:8080/examples/examplebrowser Cheers, -- Pavel

Seaside 3.0 Metacello Configuration broken for Squeak?
by Alexander Lazarević 07 Aug '11

07 Aug '11

Hi! I can't load Seaside 3.0 via Metacello into the latest trunk image. It stops with a dependency exception: This package depends on the following classes: ExecutableBlock In the transcript I get as one of the last entries something that seems to be wrong for Squeak: Evaluated -> Metacello-MC >> gemstone10beta24PreLoadDoIt I guess most Seasiders don't give a nack about this and I would offer to help fix this, but I haven't dealt with writing Metacello configurations yet. Thanks, Alex

Problem with serving static files on seaside 3.0 and lighttpd
by Mark Ross 07 Aug '11

07 Aug '11

Hi all! I tried hard in the last days to serve static files for my seaside application, but had no success. I want to leave static files on the server (/var/www/resources/css/*; js/*; images/*) and access them from within my seaside application e.g. by anHtmlRoot javascript url: '/resources/js/flotr.js'. This works for me, until upgrading to Seaside 3. My configuration: GemStone/S 64 3.0.0, fastCGI, lighttpd, Debian stable 64 bit. GemStone/S, Seaside, fastCGI and lighttpd are running perfect, but I can´t access static files (/var/www/resources) from within Seaside (e.g.: /resources/css/screen.css not found ). I have to configure seaside to handle the resources directory to access the static files - but I have no idea how. FastCGI is handling all the requests up from '/' My lightttpd config(part for fastcgi) - Thanks to Miguel Cobá (http://miguel.leugim.com.mx/index.php/2008/09/27/gemstones-and-fastcgi-with…): # forward the request to the fastcgi hosts fastcgi.server = ( "/" => ( ( "host" => "127.0.0.1", "port" => 9001, "check-local" => "disable"), ( "host" => "127.0.0.1", "port" => 9002, "check-local" => "disable"), ( "host" => "127.0.0.1", "port" => 9003, "check-local" => "disable") ) ) # enabling server dir listing to prove if lighttpd is serving the files - ok server.dir-listing = "enable" -> When I switch off fastcgi server I can lighttpd is serving the files. I tried to add: * a new Seaside Dispatcher: 'resources' with server path '/var/www/resources' * configuration in lighttpd: alias.url += ( "/resources/" => "/var/www/resources" ) * url.rewrite-once = ( "^(/resources.*)$" => "$1", "^(/.*)$" => "/$1" ) * I read the seaside docs, the web and book.seaside.st (which covers static file serving, but with apache) I think it is no difficult setting. Anybody out to help? Best regards Mark

Swazoo bugs that can affect Seaside
by Dale Henrichs 07 Aug '11

07 Aug '11

In the last week or so, I've run into a couple of bugs in Swazoo that may be of interest to any Seasiders using Swazoo in their applications. I've got workarounds for GLASS if anyone is interested. The first bug is in SwazooURI where the query fields in an URL will be incorrectly parsed if an `&` or other special character is embedded in the value of the field. The following example illustrates the bug: | url ans1 ans2 | url := 'www.foo.com/index.html?foo=1&bar=', 'bar"sample method"^#($&)' encodeForHTTP ans1 := SwazooURI fromString: url. ans2 := SwazooURI new. ans2 fromStream: url readStream. ans1 printString = ans2 printString SwazooURI>>fromString: (called by SwazooURI class>>fromString:) prematurely decodes the input string exposing the `&` and causes the parser to think that there is an additional query field in the input url and results in the truncation of the value of the `bar` field. The fix is to remove the call to HTTPString class>>decodedHTTPFrom: from SwazooURI>>fromString: ... the subsequent parsing of the queryfields already call HTTPString class>>decodedHTTPFrom: This bug is present in Swazoo-2.3beta2.6 ---- The second bug is in WASwazooAdaptor>>requestUrlFor:. In this case WAUrl is fed the printString of the #uri (an instance of SwazooURI) as follows: requestUrlFor: aNativeRequest | url | url := ((WAUrl absolute: aNativeRequest uri printString) decodedWith: self codec). aNativeRequest isEncrypted ifTrue: [ url scheme: 'https' ]. ^ url The problem occurs because WAUrl class>>absolute: expects the url to be url encoded, but the printString for SwazooURI prints the decoded url. Again this causes problems when HTTP special characters are in the input url. The other adaptors feed the 'raw' encoded url string to WAUrl, but the Swazoo adaptor does not ... SwazooURI does not keep the encoded source url around, so in my workaround I changed SwazooURI printQueriesOn: to reencode the query parameters ... Dale

WAResponse and XML
by Jay Hardesty 06 Aug '11

06 Aug '11

Hi - I'm having a problem returning XML as a response from within a Seaside app, after moving to 3.0. I used to return XML by: self session returnResponse: (WAResponse new contentType: 'text/xml'; nextPutAll: xmlString; yourself) but t in Seaside 3.0 I get: 'You can no longer return a new WAResponse instance. You must instead modify the Response contained in the active RequestContext. Look for senders of #respond: and #response for examples.' Following the nearest examples I can find I tried: self requestContext respond: [:response | | document | document := MIMEDocument contentType: 'text/xml'; content: xmlString. response document: document] and: self requestContext respond: [:response | response contentType: 'text/xml'; nextPutAll: xmlString] but in both cases an html document arrives downstream (with XML in the body) rather than the XML itself as previously Think I'm missing something basic here... Thanks very much for any pointers, Jay

Writing an object graph into a no-sql database [WAS] Re: [Seaside] ESUG SummerTalk - Fuel, binary object serializer

Sorry to come back with this old post, but now I am interested ;) Right now, I have a requirement where I need to write a graph into a file. I am using Fuel for that. Each graph, has its own file. In the image side I just store the filename, When I need to load it it reads such file and materialize it with Fuel. I was thinking going a step forward and use a key/value (a.k.a no-sql) database. With Fuel, I can take a graph, and serialize directly into a ByteArray, hence I can take a graph to swap, I assign an ID, and and save it into the database. In the image side, I keep that ID. Then, when needed, I search it in the database and then after with that ByteArray found, I materialize it with Fuel. So...first question is, do you think that could be faster/better than directly writing into a file as I am doing now? Now, which are the available Pharo wrappers for no-sql databases that let me do that? I would appreciate any link or documentation about them. What do I need to use such databases from Pharo? FFI and a library installed in my machine? are there binaries for Mac OS? Thanks in advance, -- Mariano http://marianopeck.wordpress.com
