Re^4: Avoiding perl's Atof when assigning floating point values

in reply to Re^3: Avoiding perl's Atof when assigning floating point values
in thread Avoiding perl's Atof when assigning floating point values

Hi! Running the code you offered (in a container, though), I've got:

lib/locale ..................................................... FAILE
+D at test 427
lib/locale_threads ............................................. skipp
+ed
[download]

I'm running Debian 9.4; my locale is ru_RU.UTF-8. The failures might be related to the fact the my locale (like some European ones) uses a comma (,) as decimal separator¹, unlike a dot (.) as expected by "C" locale: https://paste.debian.net/1035555/ (a PM post doesn't seem to be enough for this log).

Here is my %Config, as obtained by cd t; ./perl -I../lib -MData::Dumper -MConfig -e'print Dumper \%Config':

Is there anything else I could send you?

¹Yes, it has bitten me in the past when I wrote a library to talk to a device using standard C string formatting functions, then something else in the process called setlocale(LC_ALL, "") and everything got broken.

Re^5: Avoiding perl's Atof when assigning floating point values by syphilis (Archbishop) on Jul 29, 2018 at 00:59 UTC
UPDATE: Since writing this post, I've managed to reproduce the lib/locale.t failure on my Ubuntu-16.04 box by switching locale to LANG=de_DE.UTF-8. I now just need to make sense of what I'm seeing. The failures might be related to the fact the my locale (like some European ones) uses a comma (,) as decimal separator, unlike a dot (.) as expected by "C" locale Then I wonder if I might be able to strike the same issues on my Ubuntu-16.04 box by messing with its locale settings. I'll have to at least give that a try. I've no experience with messing with locale settings - but I expect that google has lots of advice to offer on how to do this. I'm sure that my patches affect only the values that are assigned - they change nothing about the way that values are displayed. If C's strtod() doesn't honor the locale when parsing the input string, then that would cause breakage. However, in such a case I would expect more extensive breakage than just a lib/locale.t failure. And, of course, such a perl would have no business in defining Perl_strtod in the first place - and the default that allows the defining of $Config{d_strtod} ought to be changed. Could you test one more thing for me, please ? When (if) you have the time, could you rebuild that source with the addition of `-Ud_strtod` to the configure args. That is: `make distclean sh Configure -des -Dusedevel -Duse64bitall -Ud_strtod && make && make +test` [download] I'm hopeful that will allow the lib/locale.t tests to pass without introducing more breakage elsewhere. Thank you very much for the trouble you've taken and the information you've provided. Cheers, Rob	[reply] [d/l] [select]

I've been a little despondent about the lib/locale.t failures ever since I became aware of them a few days ago. But, tonight, I think I've found the correct way to deal with them. Under `make test` there seems to be only the one failing test in lib/locale.t, but there's an additional 4 tests that fail if one runs `./perl -I./lib -T locale.t` There's no problem with those 5 tests on quadmath builds, irrespective of locale ... why is that ? ... it's because they're skipped on quadmath builds. It then dawned upon me that if it's ok for quadmath builds to skip those tests, then it's ok for my patched approach to also skip them. (Like the quadmath builds, my approach also assigns NVs using the underlying C compiler via Perl_strtod.) Having just modified lib/locale.t to skip those tests whenever Perl_strtod is defined, I find that all tests now pass !! I just need to provide patches against current blead, and hope that I can get Karl and/or Jim to create another smoke-me branch for more testing. If I can just get those patches into blead .....

It then dawned upon me that if it's ok for quadmath builds to skip those tests, then it's ok for my patched approach to also skip them However, quadmath's inability to pass those tests didn't change any pre-existing behaviour, whereas my patches have changed behaviour - and that might not be greeted so warmly. I probably ought at least find out exactly what that change of behaviour is - though it's as clear as mud to me at the moment. It would be great if anyone has some clear code that demonstrates what has actually changed. In the meantime, it's back to perusing the perllocale docs and lib/locale.t. (Is there some other documentation that might be helpful to me ?) Cheers, Rob	[reply]

I've managed to reproduce the lib/locale.t failure on my Ubuntu-16.04 box by switching locale to LANG=de_DE.UTF-8. I wonder if it's possible to force a particular `LC_NUMERIC` which has `decimal_point "<U002C>"` in `/usr/share/i18n/locales/$locale` for the `lib/locale.t` test set, while keeping it `C` for other categories as a way of verifying the cause of the failures. `make distclean sh Configure -des -Dusedevel -Duse64bitall -Ud_strtod && make && make +test` [download] `lib/locale.t` passes, but other tests don't: `Failed 2 tests out of 2458, 99.92% okay. ../ext/POSIX/t/posix.t run/locale.t` [download] But that's not too mysterious: Read more...

`Failed 2 tests out of 2458, 99.92% okay. ../ext/POSIX/t/posix.t run/locale.t` [download] Yes, the first thing I tried when I discovered I could reproduce the failures was to test a build configured with -Ud_strtod. I got the same results as you. I apologise for not having tried a bit harder to reproduce the lib/locale.t failure. I assumed that Carlos' smoker would be using the same locale setting for all of the systems that it tested. That is, I assumed that the reason that some systems passed and others didn't was because of some difference in the systems. But, of course, it was the difference in the locale settings. It was a bad assumption on my part. (They always are.) As I mentioned in my last post, I'm confident that the correct fix is to modify lib/locale.t and that's the solution I'll be pushing when I get things organized.

UPDATE: Patches for t/run/locale.t and ext/POSIX/t/posix.t have been submitted to perlbug - see https://rt.perl.org/Ticket/Display.html?id=133417 UPDATE 2: Those patches to t/run/locale.t and ext/POSIX/t/posix.t have now been applied to bleadperl. Oh ... I failed to specifically thank you for providing those 2 patches. I'll certainly be including them as I think that -Ud_strtod builds should be supported. With current perl source there's no point in building with -Ud_strtod (or -Ud_strtold) but with the patches I'm proposing, those switches provide the simplest way to resort to using perl's Atof for assigning floating point values. I don't expect that anyone in their right mind would want to opt for using perl's Atof, but I think the option should remain and the test suite should pass all tests. Cheers, Rob	[reply]
