two strings with same constituents compare as not equal

Why would two strings in a test method compare as not equal when, if you
explore them they have the same characters and are of the same class?

Paul,

That shouldn't happen ...

I'd like to get my hands on one of those boys...

I have seen cases when porting tests from Pharo where Strings and Symbols get used interchangeably (Strings and Symbols compare #= in Pharo and not in GemStone ... according to ANSI String and Symbols should not compare #=) causing the tests to fail miserably ...

Hi Dale,

I uploaded an extent here:
http://dl.dropbox.com/u/4460862/ical-test-for-dale.dbf

Its from a 3.1.0.1 extent from the install script on
seaside.gemstone.com with no updates to GLASS applied.


One test that exhibits the issue is this one:
ICConversion>>testParseString

some of the others also have the same problem including:
ICVCardTest>>testParseSurendar
ICVCardTest>>testParseOscar

Also I have some squeak compatability methods I'll upload soon.


Thanks for taking a look.


Paul

Hi Dale,

If you want to load all that stuff into a clean extent you'll need the
Squeak package I uploaded to Gemsource here:

http://seaside.gemstone.com/ss/monticello/


and the configuration from

http://www.squeaksource.com/ical

then

ConfigurationOfICal project stableVersion load:'Tests'

and proceed through a warning about True/False classes not existing.

The problem has to do with differences between the line end character used in Gemstone and Pharo...

Strings in methods will typically end up a Character lf in GemStone and a Character cr in Pharo while the generated Streams will end up Character cr (since it is explictly added by the code) ... at some level it is just happenstance that the tests work in Pharo ...

I'm a bit surprised to see that the inspector reported Character cr, but explicitly grabbing the characters and comparing the integer values revealed the problem (when I saw that the String was embedded in the method I knew that the line end character had to be the culprit):

  | x y z |
  y := Array new.
  z := Array new.
  expected do: [:each |y add:  each asInteger].
  actual do: [:each | z add: each asInteger].
  x := {y. z. }.

The fact that the debugger showed Character cr is a new bug ... in the past I didn't have to resort to the asInteger trick to identify the problem, so I'll have to dig around a bit to see who's lying ...

I wish tODE was ready as a replacement for GemTools, but it's not quite ready yet ...

Paul,

When I tried it again, I got the right answer in GemTools, so I may have been dreaming that the inspector lied to me ... When a test string is embedded in a method I use #withSqueakLineEndings or (#withGemstoneLineEndings) to coerce both strings to use the same line ending convention ...

Thanks Dale.  It was odd to me that they had the same integer value and
didn't compare as equal.  But I could easily have just been misreading it.

Hi Dale,

I have tried tODE and found it fascinating. Here is my vote for "getting it in shape for general use."

Bruce Prior

I might have to try harder to find the bug in GemTools...or better yet get tODE in shape for general use ...

Bruce,

The tODE that you probably tried was running in a web browser?

The current incarnation of tODE is an outgrowth of a project called topez[1] (screenshot and Smalltalks 2012 talk video). Instead of using a web browser, I'm using Pharo1.4, so as a developer, you can have a multi-window environment ... there's also an "object shell" (the topez bit) where all of the "files" are actually objects and the scripting language is Smalltalk ... it's a shell because you run commands with a CLI ....

With this incarnation I really feel that I've been able to accomplish a number of the goals that I set out to achieve with the web-based variants....

I would say that tODE is currently in a pre-alpha state ... I'm using it daily in my development but it needs a handful of features to make it complete.

Hi Dale,

Yes, I was running tODE in a web browser. But I have now watched your 2012 talk video and can see that there's another perhaps better way. I'll have a look at it. Thanks for all your effort; you have expanded the scope of my thinking about smalltalk.

Bruce
 

Bruce,

The tODE that you probably tried was running in a web browser? 

The current incarnation of tODE is an outgrowth of a project called topez[1] (screenshot and Smalltalks 2012 talk video). Instead of using a web browser, I'm using Pharo1.4, so as a developer, you can have a multi-window environment ... there's also an "object shell" (the topez bit) where all of the "files" are actually objects and the scripting language is Smalltalk ... it's a shell because you run commands with a CLI .... 

With this incarnation I really feel that I've been able to accomplish a number of the goals that I set out to achieve with the web-based variants....

I would say that tODE is currently in a pre-alpha state ... I'm using it daily in my development but it needs a handful of features to make it complete.

Dale

Dale,

how does topez/tode compare to gemtools when it comes to roundtrip times (windows et. al)? You know the Omnibrowser stuff takes away the fun of using gemtools being sooo chatty.

Norbert

Norbert,

topez/tode is built from the ground up to be frugal with round trips.

topez/tode over the WAN feels like GemTools over the LAN...topez/tode over the LAN is pretty snappy ...
