Hiesenbug with "unicode spew"

Hi All,

I discovered that the "unicode spew" was not what I thought it was.
When the "spew" happens it is because the html output is dumped within the
body tag like this:

<html>
<head></head>
<body><�!DOCTYPE
html><�html><�head><�title>Seaside<�/title><�meta
charset="utf-8"/><�link rel="stylesheet" type="text/css"
href="/files/WADevelopmentFiles/development.css"/><�/head><�body
onload="onLoad()"><�a
href="/waDebug?_s=ccLzvr_77iZO7bVN&amp;_k=KdqQxjU4LkFiBg30&amp;1">standard
dash<�/a>&nbsp;<�a h
</body>
</html>

Its wierd and its a heisenbug.

I created a copy of WACounter , named it WADebug and the callbacks "dash"
and "mdash" totally isolate the Character.

http://menmachinesmaterials.com/waDebug

*renderContentOn: html

html anchor
callback: [ self dash ];
with: 'standard dash'.
html space.
html anchor
callback: [ self ndash ];
with: 'n-dash'.
html break.
html html: count.

dash
count := '-'

ndash
count := (Character value:8211) asString

*

What is really weird is that it works on the server when it did not work on
my workstation.
For some reason, it just started working on my Workstation.
I made a small edit to my Workstation, unrelated to that issue, and it
stopped working.

I am running Seaside on
Squeak5.2
latest update: #18233

Anybody have a clue why it would mangle the output like that?

I will be trying a Pharo install possibly tomorrow to see if that negates
the bug.

cheers.

Re: Hiesenbug with "unicode spew"

Hi All,

First, my apologies for the multiple posts. When I did not see my message
appear, I assumed I had messed up and reposted.

I believe that the "Unicode Spew" is a result of the parse taking longer
than the Seaside Render loop and/or errors in the parse not being handled.

If you go here: http://menmachinesmaterials.com/WikitextParser click the
Hamburger Icon->Database->Blade Runner, it creates the unicode spew every
time.

If I run the same parse within the image as a workspace Doit, it works just
fine.

Here is the bulky thing, it is a sub-message of renderContentOn:html

*renderParsedOn: html
| wikiGrammar wikiParser input actor s|

actor := PEGWikiMediaGeneratorTables new.
actor transcripton
ifTrue:[ Transcript clear].

wikicode isNil
ifTrue:[input := '== Welcome To WikitextParserBrowser ==']
ifFalse:[input := wikicode].

wikiGrammar := PEGParser grammarWikiMediaTables reading positioning.
wikiParser := PEGParser parserPEG parse: 'Grammar' stream: wikiGrammar
actor: PEGParserParser new.
[[output := wikiParser parse: 'Page' stream: input actor: actor. ]
on: Error
do:[:ex | output := '
Error parsing. see Wikicode tab for source
<code>', ex description, '</code>' ]]
ensure:[
s := ((output asString copyReplaceTokens: '<body>' with:'' )
copyReplaceTokens:'</body>' with:'') .
s := s copyReplaceAll:'>' with:'>' asTokens:false.
s := s copyReplaceAll:'<' with:'<' asTokens:false.
html break;break.
html html: s.
].*

I think the "Render Loop" just cannot handle that call when things go south.

Thank you all for your patience and advise.
