isolate

Hi, Given it looks like the isolate method is never going to added back to the current or future versions of Seaside as it's been an open bug issue for the last 5 years, how in general would go about replicating it's behaviour ? I think it's a shame as I think this sort of functionality made Seaside standout from the crowd as a web framework. Thanks

random maddening bug - "corrupted" file upload contents
by Cyrille Delaunay 17 Jan '18

17 Jan '18

Hi everyone, Since some times, we are experimenting a random bug while using seaside file upload. Not sure at all about the exact origin of this issue (Application specific, Zinc, Seaside, Pharo ?). But as it start to drive us mad, I'm sharing our problem with you. Maybe someone would already have experimented something similar or would have a good feeling about the issue. *High level description:* We have a file upload element rendered with seaside. The callback of this file upload element is triggered when the form is submitted via a submit button. Problem: Within this callback, the raw contents of the WAFile does not match the expected contents of the selected file. The first 4 bytes are "wrong", and rest of the byte array seems ok. This issue occurs randomly and we haven't been able to determine / guess any context criteria. *Debugging:* In order to figure out what was wrong, we tried to catch a place in pharo where file contents started to differ from the expected file contents. The earlier upload step in which we have been able to notice this delta, is method ZnMultiThreadedServer >> executeOneRequestResponseOn: In this method, a http request is read and materialized from an input stream, >From my naive point of vue, this stream looks like a kind of communication entry point between the web browser and pharo. The zip input file I am trying to upload is expected to begin with the following bytes: #[80 75 3 4 10 0 0 0 0 0 125 83 67 73 ... The request object built within #executeOneRequestResponseOn: points to an"entity" variable, which points to a "parts" variable, which points to a single ZnMimePart. This ZnMimePart points to a byte array beginning with: #[0 0 0 0 10 0 0 0 0 0 125 83 67 73 ... I also experimented another case where The request object built within #executeOneRequestResponseOn: points to an"entity" variable, which points to a "parts" variable, which points to multiple ZnMimePart. One of the ZnMimePart points to a byte array beginning with: #[138 67 80 75 10 0 0 0 0 0 125 83 67 73 We can see that in both cases the first 4 bytes do not match the expected first 4 bytes of the file. As a consequence, later in our process, pharo gets a error while trying to unzip this upload file, complaining about a "'bad LH signature at 0'". Does this speak to anyone ? -- Cyrille Delaunay

Oh, shucks. Didn't open the stack up far enough! Back to the drawing board (or keyboard!). Thanks Joachim. Note to self: check the obvious first! (I wouldn't mind but I have been writing Smalltalk for 27 years so I should know this).

Date: 12/19/2017 13:35:58 (Tue) David I guess you should take a closer look at this part of the Stack: OrderedCollection(SequenceableCollection)>>#first self=OrderedCollection() OrderedCollection>>#first self=OrderedCollection() TM470User>>#carCardForRoadNumber: self=a TM470User id='BM:33549' [] in TM470CurrentTrain>>#constructCarsUsing: self=a TM470CurrentTrain aUser=a TM470User carArray=OrderedCollection('BM:33549' 'BAR:6724' 'CP:240000' Seems like you try to use the first element in an empty Collection. Not related to Seaside, afaik. Joachim David Pennington hat am 19.

Rendering pre-formatted html
by kmo 08 Dec '17

08 Dec '17

How do I render a piece of pre-written html in Seaside? For example, if I have: renderContentOn: html | htmlFragment | htmlFragment := 'I am renderedas text>'. Then how do I render this as html code rather than as a literal string? Thanks in advance for any help. -- Sent from: http://forum.world.st/Seaside-General-f86180.html
