[racket-dev] ffi sizeof bool

i guess this shouldn't happen:

#include stdio.h
int main()
{
printf(%zu\n, sizeof(bool));

Re: [racket-dev] [plt] Push #28468: master branch updated
I'm not completely clear on the precise impact of old papers: will the plot itself stay the same size, but the relative size of the font (to the other plot elements) inside the plot change only? Or something else?

Re: [racket-dev] Compile cache being incorrect
If I understand the question: * With 34c3eed615, pr12644.rkt can compile and run. * With d29df205f7, pr12644.rkt fails to compile. * A bytecode form of pr12644.rkt compiled with 34c3eed615 can still run in d29df205f7, because run-time support for pr12644.rkt didn't change. * When you tell `racket` to run pr12644.rkt, it will use a .zo for each of pr12644.rkt and its dependencies as long each individual .zo file has a newer timestamp than its .rkt file. That is, the only timestamp comparisons are on individual .rkt and .zo pairs. * When you tell `raco make` to build pr12644.rkt, it checks dependencies (via .dep file) and compares a .rkt file's timestamp against the times of all of its dependencies, instead of just checking individual .rkt and .zo pairs. That's why a `raco make` in d29df205f7 tries to recompile pr12644.rkt.

Re: [racket-dev] ffi sizeof bool
Yes, `_bool` is a problem. I'll add a `_stdbool` that corresponds to
`bool` from C99's stdbool.h, which I imagine must be the same as
`bool` in C++.

Re: [racket-dev] [plt] Push #28468: master branch updated
Yes, the relative size of the font will grow, as well as minor things, such as that the lines will thicken a bit. IOW, without the fix, if you output the same plot to a PDF, SVG, and PNG, the PDF will have a smaller font and thinner lines than the SVG and PNG. It can be hard to tell without converting them to the same format for comparison, which is why I didn't spot this for so long. I just thought papers looked better when plots had slightly larger fonts. I verified that the fix works by using the Gimp to convert a PDF and an SVG to two 500x500 images, and pasted one over the other.

Re: [racket-dev] ffi sizeof bool
The current `_bool` is pre-standard. It specifically reflects (I think)
the absence of a bool type in libffi, which in turn is an artifact (I
assume) of `bool` not existing in a C standard before C99.
Lots of libraries have a bool variant that is `int`-sized, so I
imagine that's where the definition of `_bool` came from. For example,
boolean fields in public libjpeg structures are `int`-sized as the
library is usually built (except on Windows). Similarly, a `gboolean`
in GLib is an alias for `gint`, which is an alias for `int`.

Re: [racket-dev] Fwd: Create executable problem
[ Nadeem sent me the file offline. ] I've pushed a fix for the bug. It is possible to work around it: the issue comes up when you copy and paste the result of the 2htdp/image images back into the definitions window. In this case, the image I noticed that does this is a flipped cat. So you could delete that from the file and then put (presumably at the top-level) a call to flip passing in the literal cat and then just use that instead. That should work with the released version.

Re: [racket-dev] Create executable problem
Thanks for your work, Robby. --- nadeem On Friday, April 4, 2014, Robby Findler ro...@eecs.northwestern.edu wrote: [ Nadeem sent me the file offline. ] I've pushed a fix for the bug. It is possible to work around it: the issue comes up when you copy and paste the result of the 2htdp/image images back into the definitions window. In this case, the image I noticed that does this is a flipped cat. So you could delete that from the file and then put (presumably at the top-level) a call to flip passing in the literal cat and then just use that instead. That should work with the released version.

Re: [racket-dev] Compile cache being incorrect
Great that explains it and with that information I was able to simplify my test case to tmp.rkt #lang racket (require tmp2.rkt) (define-syntax (go stx) (foo)) (go) tmp2.rkt #lang racket (provide (for-syntax foo)) (begin-for-syntax (define (foo) #'3)) So now the question is how do I run my code so as to not be bit by this? I want a command to run my program that is both fast to run and correct with regards to my source. My previous assumption was that the zo file's logic was safe if I wasn't trying to break it but I now know better. Is my only option to either always compile or never compile?

That is, the only timestamp comparisons are on individual .rkt and .zo pairs. * When you tell `raco make` to build pr12644.rkt, it checks dependencies (via .dep file) and compares a .rkt file's timestamp against the times of all of its dependencies, instead of just checking individual .rkt and .zo pairs. That's why a `raco make` in d29df205f7 tries to recompile pr12644.rkt.

I am under the impression that if I compile a file and then change a (transitive) dependency of it, then it should have to be recompiled, but I am not seeing that.

[racket-dev] Internal crashes
I have seen a crash that looks like this twice recently. Seg fault (internal error during gc) at 0x19fd08000 I reran the same program and would not get the crash again.
