QA Notice: Package triggers severe warnings #1474

 * QA Notice: Package triggers severe warnings which indicate that it
 *            may exhibit random runtime failures.
 * duk_error_macros.c:15:2: warning: implicit declaration of function ‘vsnprintf’ [-Wimplicit-function-declaration]
 * duk_bi_date.c:967:2: warning: implicit declaration of function ‘snprintf’ [-Wimplicit-function-declaration]
 * ./duk/duk_config.h:2027:26: warning: incompatible implicit declaration of built-in function ‘snprintf’
svaarala commented 7 years ago

Hmm, duk_config.h should be including which provides these: https://github.com/svaarala/duktape/blob/master/config/header-snippets/platform_sharedincludes.h.in.

It's included for all platforms, regardless of any detection because it's an assumed header and present in C89.

fatcerberus commented 7 years ago

Isn't [v]snprintf() a C99 function? Maybe the C99 detection isn't working correctly.

svaarala commented 7 years ago

But there's also a warning about snprintf().

svaarala commented 7 years ago

According to Linux man pages both snprintf() and vsnprintf() are C89, which was my recollection too. Hopefully that's correct :)

svaarala commented 7 years ago

No, actually, my bad:

       snprintf(), vsnprintf(): POSIX.1-2001, POSIX.1-2008, C99.

I'll need to make a note that these are assumed to be provided, and if not provided by a C89 stdio.h, they need to be filled in via duk_config.h changes.

svaarala commented 7 years ago

@blshkv Do you have -std=c99 set when you compile BTW?

svaarala commented 7 years ago

Clarified (v)snprintf() dependency in #1475.

svaarala commented 7 years ago

@blshkv Another question: what platform was this error found on? For Linux the duk_config.h header defines _POSIX_C_SOURCE which then allows (v)snprintf() even without -std=c99. But _POSIX_C_SOURCE is not currently applied on e.g. BSD platforms - so I could fix that if you let me know what platform you're compiling for.

fatcerberus commented 7 years ago

I thought those were C99, hence why this is needed on MSVC < 2015: https://github.com/fatcerberus/minisphere/blob/v4.5.10/src/cell/posix.h#L11-L13

MSVC considered the functions "non-standard" (hence the underscore) before they got serious about C99 support. An issue Duktape itself has also had to grapple with :)

svaarala commented 7 years ago

Yeah, as I said above, my bad :)

svaarala commented 7 years ago

The reason this isn't an issue on Linux (which is my development OS) is that there's a _POSIX_C_SOURCE feature define in place which allows the functions to be used even without -std=c99 (which is recommended but not always in place in application build scripts). But that define is not in place for all platforms which makes non-C99 builds complain about these symbols.

blshkv commented 7 years ago

I'm facing this issue under Gentoo Linux, we just enabled all warnings using ''' - Wall'''. I'll provide more details tomorrow

svaarala commented 7 years ago

@blshkv Ok, thanks. From what I can tell the _POSIX_C_SOURCE define in duk_config.h should be enough even without -std=c99 but let's see what's causing it.

svaarala commented 7 years ago

Just rechecked on Ubuntu 16.04.2 (gcc 5.4.0) that compiling with -Wall -Wextra, and without -std=c99 doesn't cause these warnings, so there must be some difference in compiler options, compiler versions, or something similar.

blshkv commented 7 years ago

I was in a bed, but happy to provide more details since you are so active ;-)

Thanks, I tried to replicate the exact options to gcc (and clang) but failed to reproduce on Ubuntu. So I'm not sure why that _POSIX_C_SOURCE wouldn't get applied. Could you print out Duktape.env (if that's easy) from a script, it might shed light on whether the platform wasn't detected as Linux for some reason (that would seem odd).

Also, it would be good if you could try -std=c99 on that compile line to see if it fixes the issue. If so, there's something weird going on between the feature defines and header inclusion.

blshkv commented 7 years ago

ok, the -std=c99 fixes the error, however I can not reproduce the issue on a difference system with 5.4.0 compiler.

svaarala commented 7 years ago

I could try to reproduce by installing a Gentoo VM? Or was that different system also Gentoo?

blshkv commented 7 years ago

The issue I'm facing is under vm (gcc 4.9.4) and that difference system is a Gentoo host with almost exactly the same setup. I will install gcc 5.4.0 on that vm tomorrow and report back.

svaarala commented 7 years ago

Thanks, very much appreciated.

blshkv commented 7 years ago

ok, so I have upgraded gcc to v5.4.0 and the error is gone. I guess we can close the issue

svaarala commented 7 years ago

Ok, would have been nice to know the root cause but maybe it's not worth investigating more :)

blshkv commented 7 years ago

yeah, I'm puzzled myself was it false positive or false negative. But I have no time for further investigation

svaarala commented 7 years ago

No worries, I understand, time is a scarce resource for me too :)
