WideString bug in Seaside?
by tty 24 Feb '20

24 Feb '20

Hi Folks, I may have stumbled upon a Seaside bug. I am able to turn the "unicode spew" bug on and off at will. at http://menmachinesmaterials.com/WikitextParser The middle tab "wikicode" is the culprit. The code for it is here: *renderWikicodeOn: html |src| wikicode isNil ifTrue:[src := '== Welcome To WikitextParserBrowser =='] ifFalse:[src := wikicode]. html break;break. src class = WideString ifTrue:[src := 'buggy']. html preformatted:src* The following input will blow up the render when the WideString check is commented out: * testmDashThierryIV "scratch test" ^ ' ''''''Thierry IV'''''' or ''''''Theoderic IV'''''' ({{circa}} 720{{spaced ndash}}c. 782) was a [[Franks|Frankish]] noble. Count of [[Autun]] and [[Toulouse]]; he was thought to be a son of [[Sigebert V]], and grandson of [[Sigebert IV of Raze]]. It is now well documented that his supposed Davidic blood was a hoax (see [[Priory of Sion]]). Thierry married [[Auda of France|Auda]], daughter of [[Charles Martel]], sister of [[Pepin III]]. ==Children== *[[William of Gellone]] (755 – 28 May 812/4) *Alda of Gellone (born ca. 770); married Fredalon *[[Adalhelm of Autun]] {{Persondata | NAME = Thierry 04 | ALTERNATIVE NAMES = | SHORT DESCRIPTION = Frankish noble | DATE OF BIRTH = | PLACE OF BIRTH = | DATE OF DEATH = | PLACE OF DEATH = }} {{DEFAULTSORT:Thierry 04}} [[Category:720s births]] [[Category:780s deaths]] [[Category:Counts of Autun]] [[Category:Counts of Toulouse]] [[Category:Frankish people]] {{France-noble-stub}}'* If I leave that check in, then the html renders perfectly, and the Wikicode tab just displays "buggy" If I remove that check, the "unicode spew" problem happens. I have tried several different html tags besides preformatted including text: html: code: textArea: None of that made a difference. The difference between the HTML and WIKICODE display is that the html passes through the XTreams Parsing and a grammar rule exists that changes the 'mdash' to a simple '-'. The original Wikicode that is parsed does not have those characters replaced. -- Sent from: http://forum.world.st/Seaside-General-f86180.html

Hiesenbug with "unicode spew"
by tty 19 Feb '20

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. t -- Sent from: http://forum.world.st/Seaside-General-f86180.html

A heisenbug (was Unicode Spew)
by tty 18 Feb '20

18 Feb '20

Wierd stuff. The "unicode spew" wasn't what it seemed to be; rather, the final generated html looked 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=HYflc3WPAZnUmxcX&amp;_k=oAlI2TSho5n4-x6m&amp;1">standard dash<�/a>&nbsp;<�a h </body> </html> The output was being output to the <body> tag, not the top level. I isolated the culprit. Character value: 8211 I Copied and modified the WACounter example as WADebug to generate the error; the callbacks are 'dash' and 'ndash' instead of 'increase' and 'decrease' ndash count := (Character value:8211) asString dash count := '-' http://menmachinesmaterials.com/waDebug Unfortunately, it works, and I do not know why. I run the same thing on my local workstation and I get the "unicode spew" problem. But wait! it gets weirder still. When I deployed to the server, where it works, my workstation version started working too. Yet, when I saved the method with the demo text under a new method name, the error returned. Anybody seen these symptoms before? thanks in advance. -- Sent from: http://forum.world.st/Seaside-General-f86180.html

How to think about "Unicode spew"
by tty 18 Feb '20

Hi Folks. Over at http://menmachinesmaterials.com/WikitextParser *** When hitting HamburgerIcon->Database->Random Page I occasionally get what I call "Unicode spew" Here is a portion of a page. *<�!DOCTYPE html><�html class="no-js" lang="en" dir="ltr"><�head><�title>WikitextParser<�/title><�meta charset="utf-8"/><�link rel="stylesheet" type="text/css" href="/files/WADevelopmentFiles/development.css"/>...* However, on the image, if I run the page manually, the resulting XMLElement looks just fine. Here is the thing that caused the spew. *<body> Thierry IV or Theoderic IV ({{circa}} 720{{spaced ndash}}c. 782) was a Frankish <https://www.wikipedia.org/wiki/Franks> noble. Count of Autun <https://www.wikipedia.org/wiki/Autun> and Toulouse <https://www.wikipedia.org/wiki/Toulouse> ; he was thought to be a son of Sigebert V <https://www.wikipedia.org/wiki/Sigebert_V> , and grandson of Sigebert IV of Raze <https://www.wikipedia.org/wiki/Sigebert_IV_of_Raze> . It is now well documented that his supposed Davidic blood was a hoax (see Priory of Sion <https://www.wikipedia.org/wiki/Priory_of_Sion> ). Thierry married Auda <https://www.wikipedia.org/wiki/Auda_of_France> , daughter of Charles Martel <https://www.wikipedia.org/wiki/Charles_Martel> , sister of Pepin III <https://www.wikipedia.org/wiki/Pepin_III> . Children <ul><li><a href="https://www.wikipedia.org/wiki/William_of_Gellone">William of Gellone</a> (755 – 28 May 812/4)</li><li>Alda of Gellone (born ca. 770); married Fredalon</li><li><a href="https://www.wikipedia.org/wiki/Adalhelm_of_Autun">Adalhelm of Autun</a></li></ul>{{Persondata <div/>| NAME = Thierry 04| ALTERNATIVE NAMES =| SHORT DESCRIPTION = Frankish noble| DATE OF BIRTH =| PLACE OF BIRTH =| DATE OF DEATH =| PLACE OF DEATH =}}{{DEFAULTSORT:Thierry 04}} Category:720s births <https://www.wikipedia.org/wiki/Category:720s_births> Category:780s deaths <https://www.wikipedia.org/wiki/Category:780s_deaths> Category:Counts of Autun <https://www.wikipedia.org/wiki/Category:Counts_of_Autun> Category:Counts of Toulouse <https://www.wikipedia.org/wiki/Category:Counts_of_Toulouse> Category:Frankish people <https://www.wikipedia.org/wiki/Category:Frankish_people> {{France-noble-stub}}</body>* The method that posts the output is straightforward enough: *renderParsedOn: html | wikiGrammar wikiParser input actor| 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.

If you get a DNU just hit the back button and try again. Please do not hit Debug (: -- Sent from: http://forum.world.st/Seaside-General-f86180.html
