Re: NSDateFormatter SetDateStyle / setTimeStyle not working

[Stefan Bidigaray]

I'm still trying to figure out what GNUstep is doing differently from the tests I'm sending you. As far as I can tell, the results should be identical. We really do not do anything particularly special. Short of having you step through the methods step-by-step, checking results along the way, I don't know what to do.

I'm going to install FreeBSD in a VM and more thoroughly check this out. It might be a few days until I get ti all done.

In the mean time, I fixed the test. It's attached.

Stefan,
 

the result remains correct, but now I had 2 warnings when compiling. I don't know if that has any meaning though.

I you have any ideaes about things that I could try to shed some light on this....

Kind regards,

Hmm... There definitely something wrong in GNUstep, then. The question is what!? Looking at the code, I'm not entirely sure what could be happening, and why your system is giving different results than mine. You are using ICU version 58.2, so I'm wondering if some behavior changed between what I have (version 55.1) and the later ICU releases.

I modified the previous test to verify that your version of ICU does the same thing as previous releases. Can you please recheck? Maybe later versions are be choosing the pattern over the styles. This is the only thing I can think of, right now.

Thanks

Does this mean the problem is in my GNUstep installation?

Hi Edwin,

The attached test does something very similar to GNUstep, and you should get the same answers. Can you check this out and report back?

To build:

cc test_icu.c `icu-config --ldflags --ldflags-icuio`

My results:

I'll come up with a test for ICU and post it here. I'll make sure to use the same functions used by GNUstep to verify.

I'm still betting the problem is in your ICU installation. The GNUstep code is a thin layer on top of ICU, it's unlikely that the problem lies there. I'm not saying impossible, just unlikely.

Could i run a C-program that formatted the date with locale nl and conclude
  - the problem is in my ICU installation if the result of the program is wrong?

 -  the problem is in my GNUstep installation if the result of the program is OK?

Kind regards

Hi Edwin,

From everything you've said so far, the problem doesn't seem to be in GNUstep. The method you are using would return nil if ICU wasn't installed. Additionally, the return value is what you'd expect from the en_US_POSIX locale, the default in FreeBSD.

With that in mind, have you tried explicitly setting the formatter's locale using the -setLocale: method? It's possible your setup is falling back to the systemLocale, which would be a separate problem.

Have you tried running the test I attached in my previous email?

Regards

Hello,

I return from holidays that have been haunted by this problem :-).

I asked about libicudata.so on the freebsd list. The answer was " devel/icu is built --with-data-packaging=archive which means the data ends up in icudt* file e.g.,

$ pkg info -l icu | fgrep icudt | xargs du -Ah
 25M    /usr/local/share/icu/58.2/icudt58l.dat"

We compared the necessary ICU libraries and they all are present at my side, with more or less equal sizes.

In the config.log file for gnustep base, I found:
...
HAVE_GNUTLS='1'
HAVE_ICU='1'
HAVE_INET_NTOP='yes'
HAVE_INET_PTON='yes'
HAVE_LIBDISPATCH='1'
HAVE_LIBXML='1'
HAVE_LIBXSLT='1'
HAVE_MDNS='0'
HAVE_OBJC_SYNC_ENTER='yes'
...

This seems to indicate ICU is used. Just to be sure, I added

#if GS_USE_ICU == 1
      NSLog(@" GS USE ICU == 1");
#endif   

to my program, and effectively, the display appeared:

2017-09-14 11:04:41.625 TM1[79500:100088]  GS USE ICU == 1

I tried debugging, but from a recent conversation on this list, it seems I need a port gdb80, that is not present in my FreeBSD 11.0 ports directory  (have got gdb and gdb66).

I must be missing something obvious, but for now, I'm rather stuck. Problems like this make one feel utterly stupid.

Would you have any suggestions left?

(I already reinstalled the icu and gnustep base ports, no errors detected, no change in the result).

Kind regards,

Edwin.
