My changes in response to pr11xyz. I ran the language test suite. I had no clue that language changes can affect drrracket test suites. Sorry. Done. On Oct 14, 2010, at 9:48 AM, Robby Findler wrote: The teaching language error message wording changed slightly, breaking some of the

No problem. That's what drdr is for! :) But I'll go ahead and add you to the relevant test suites reporting. You might want to try them out, just so you get a sense (they're really testing the integration of the teaching langauges into drracket, so the precise wording is incidnental; they're

[racket-dev] question about your change to run-teaching-languages.rkt

2010-10-14 Thread John Clements
Back on October 11, you made a change to run-teaching-languages.rkt that works absolutely fine with the stepper. ...but it breaks the stepper's testing harness. Ugh. The problem, IIUC, is that the expansion of the teaching-language programs refer to a module, test-engine/racket-tests, that

[racket-dev] expected timing difference between fft-complex-forward and fft-complex-radix2-forward?

2010-10-14 Thread John Clements
On a vector of length 8192 (a power of 2, natch), fft-complex-radix2-forward takes about 1/8 of a second (lost in the noise, essentially), but fft-complex-forward takes more than 24 seconds, a difference of about 200x. They do produce the same answers, up to differences of 1e-4 in the

I will factor out the error message generation for 2htdp/*sl. Perhaps I can combine it with htdp/error. You should then be able to simplify the drracket tests. _ For list-related administrative tasks:
