@niconiconi And autotools tests are like 90% useless on any computer that's outside of a living computer museum.

@niconiconi Meanwhile the basic ./configure script for my browser:$ dumbbench --float ./configure[bunch of output]cmd: Ran 22 iterations (2 outliers).cmd: Rounded run time per iteration (seconds): 0.056690 +/- 0.000170 (0.3%)

@niconiconi @not2b Yeah but there's no reason to parallelize them, the vast majority ought to be well under a second on current computers.It's supposed to be configuration, not a weird testsuite, specially in current era where you can eventually get rid of workarounds.

@niconiconi @not2b It's not a testsuite but it sure loves to test if the system is somewhat modern, like yes I'm not running SunOS from 1987, you should be able to expect a somewhat POSIX environment by now.(And if I wanted a special strstr implementation I'd just put the one that I like, it's like what 10~20 lines of C)

@niconiconi @not2b SunOS thing also being a bit interesting because the test is still there even though the rest of the buildsystem doesn't supports SunOS at all.

@niconiconi @lanodan @not2b > shell scripts are inherently sequentialFunny you should say that...https://www.usenix.org/conference/osdi22/presentation/kallasThis research group wrote a JIT(!) for bash(!!) that also automatically parallelizes the code (!!!)

@lambdageek @niconiconi @not2b Sounds like the best way to have a ton of bugs everywhere if you'd use it as /bin/sh

@niconiconi @gracicot @vikxin > B2 makes it easy to build C++ projects, everywhere.That's like how the S of SOAP stands for Simple.

@lambdageek @niconiconi @not2b Practice vs. theory (I'd say testsuites are somewhat in-between) moment.

@lanodan @niconiconi @not2b From the abstract:> When run on a wide variety of benchmarks, including the POSIX shell test suite, PaSh-JIT (1) does not break scripts, even in cases that are likely to break shells in widespread use; and (2) offers significant speedups, whenever parallelization is possible. These results show that PaSh-JIT can be used as a drop-in replacement for any non-interactive shell use, providing significant speedups without any risk of breakage.So... no?

@dpflug @lambdageek @niconiconi @not2b Jit for an init?https://www.tuhs.org/cgi-bin/utree.pl?file=SysIII/etc/rc obviously doesn't needs that.

@lanodan @niconiconi They also almost universally invoke undefined behavior, making them increasingly spicy with modern compilers and linkers.

@lanodan @niconiconi But what I actually wanted to write was: âA living computer museum? That's me!!!âIt's quite unfortunate that most software happens to test for all the features, but then tries to compile against them even if they are missing, because no-one actually runs their code on HP-UX 10.x or IRIX or whatever.

@vjon @niconiconi Yup, they're not supported platforms (part of me wishes they would be, it would probably have avoided illumos being pretty much gone and forgotten post-oracle).To me it's like, if you have platform-specific code, specially workarounds, it's for supported platforms, possibly with some kind of CI or a known-maintainer.

@mawhrin @lambdageek @niconiconi @lanodan @not2b In the 2000âs I built a whole config-mgmt toolkit which used that functionality to herd a mixed Solaris/OSF1/Linux world of a couple hundred machines from a single modest Sun box. Obviously one must handle all the asynch issues in harvesting results, but thatâs a SMOP. I would think (with the freedom of having not lookedâŚ) that autoconf could run batches of tests.
