Re: the future of testing
I think the data will support the idea that a directory structure based
on OS/CPU is probably not the way to start.
Quite possibly. The proposed file could suffer from the same combinatorial
explosion, if not properly structured. Does anyone have a good idea of the
most economical structure for the exceptions? I do like the idea of
embedding conditions in data rather than code structures, though.
Instead, one might consider generating that list of exclusions based on
the actual results of running Configure.pl. The program that generated
that skip list might consist of lines like
print t/op/64bit.t unless $PConfig{intvalsize} == 8;
Or touch x.t if some_state. As the problems of maintaining lists of
filenames have already been solved, it seems a shame not to use well-known
tools like ls, rm, diff, and their friends.

Re: the future of testing
Some hand-waving on the problem of configuration and test selection, (as the two appear to share the issues, an ideal solution would address both). For any usable environment, a large set of common processes have to be executed, with a smaller, OS /|| CPU specific set omitted. One way to do this might be to have all possible steps in a common process directory, with a mechanism to drop the unwanted ones. Any process invoked could assume that it has the right to run. A possible scheme might be a directory hierarchy matching the OS/CPU combination, e.g. Linux/x_86, Linux/i_64, Solaris/Sparc, containing dummy files whose names match the processes NOT to be run for that environment. (The precise structure would depend on which combination required the fewest cases; it's dictated by the data.) The steps would be: Identify the environment Select the list of corresponding exclusions (list the directories) Eliminate them from the to-do directory's listing Execute the remaining list *nix environments can probably do this with standard tools, and Microsoft copied the filesystem structure closely enough that it shouldn't be a serious challenge. Does this sound plausible and portable enough to be worth prototyping? -- Email and shopping with the feelgood factor! 55% of income to good causes. http://www.ippimail.com
Re: Repeated Loopy Variable Width String Character Access is Slooooow-ish
Jarkko's view was that if he were doing Perl 5 Unicode again he would opt for fixed width 32 bit rather than UTF-8, It seems to be a general principle of system design that the best way to process irregular and unpredictable things, is to grab them as close to the outside of the system as possible, make sure they're not dangerous, stuff them into closed, standard boxes, and only deal with the problems of the boxes. This is illustrated examples as diverse as disk-drives, (which went from variable-length to fixed-sized blocks early in their development), to container shipping. It's not insane to have the boundary near the outside of parrot. Any system that doesn't assume input from the outside world to be toxic until proven otherwise is being dangerously naive. However, paranoia's expensive, so you want to concentrate it as much as possible. -- Email and shopping with the feelgood factor! 55% of income to good causes. http://www.ippimail.com
Zombie code?
While trying to understand Parrot::Vtables.pm, I came across what seems to be some zombie code, possibly left after RT 48877. 1. Two references to src/pmc/null.pl, which does not appear to exist. 2. The method vtbl_embed, which is used only in parrot/tools/build/vtable_extend.pl That writes include/parrot/extend_vtable.h and src/extend_vtable.c, neither of which exist. 3. Some odd pod in the method around lines 368-372, which makes me think the expression that spans 367-379 would behave rather oddly if the method was ever used.

Re: [perl #49274] [CAGE] script to generate ports/debian/parrot-doc.docs
A quick cage cleaner task. Create a script to generate the file ports/debian/parrot-doc.docs I've attached a quickie shell script, in case that's what you want. It's a naive little thing, but I think you'll be amused by its presumption.

James E Keenan wrote: For portability reasons, however, shouldn't it be converted to Perl 5? The difference here is that you can only generate Debian packages on a Debian-based system, so portability to non-Linux systems isn't a concern. That was my assumption.

I'll put in the refinements Allison suggested, then use that as the spec. for a Perl script, if somebody doesn't beat me to it. -- Email and shopping with the feelgood factor! 55% of income to good causes. http://www.ippimail.com
Re: Testing asynchronous code
In the concurrency work I'm about to check in, I have some tests that fail intermittently because they test for something like: But, as we add more asynchronous code, and more asynchronous tests, we'll need to do more thinking on our strategies for testing asynchronous code. Would always sorting the expected and actual output to the same order solve the problem?
