Using 5.6.30

PHP Warning: PHP Startup: Unable to load dynamic library '/builddir/build/BUILDROOT/php-phalcon3-3.2.0-1.fc24.remi.5.6.x86_64/usr/lib64/php/modules/phalcon.so' - /builddir/build/BUILDROOT/php-phalcon3-3.2.0-1.fc24.remi.5.6.x86_64/usr/lib64/php/modules/phalcon.so: undefined symbol: zend_error_noreturn in Unknown on line 0

zend_error_noreturn is part of PHP public API in 7+ only

5.6.30:
void zend_error_noreturn(int type, const char *format, ...) __attribute__ ((noreturn));

7.0.20
ZEND_API ZEND_COLD ZEND_NORETURN void zend_error_noreturn(int type, const char *format, ...);

The text was updated successfully, but these errors were encountered:

Notice: it fails on startup when PHP is built with some special option, but it will segfault on runtime with default PHP build options.

remicollet · 2017-06-19T07:00:16Z

Issue could be in zephir (latest tagged version 0.9.8 used)

PHP is built with some special option

Which one? Could you elaborate on that? I need steps to reproduce.

Cc: @phalcon/collaborators Does anyone faced with this?

remicollet · 2017-06-20T04:13:25Z

Which one? Could you elaborate on that? I need steps to reproduce.

Some Linux distributions use RTLD_NOW (all symbols resolved at startup) instead of RTLD_LAZY (resolved at runtime) for security enhancement reason.

remicollet · 2017-06-20T04:23:23Z

Ex, patch for 5.6 used in Fedora (also in RHEL, CentOS, ...)
http://pkgs.fedoraproject.org/cgit/rpms/php.git/tree/php-5.4.0-dlopen.patch?h=f24

Debian patch
https://anonscm.debian.org/git/pkg-php/php5.git/tree/debian/patches/0034-php-5.4.0-dlopen.patch

Also -z relro -z now linker flags used.

Or https://derickrethans.nl/undefined-symbol.html

sergeyklay · 2017-06-20T04:30:10Z

@remicollet Well, anyway I need to reproduce this to be able debug. So I'll try to sort out.

zend_error_noreturn is part of PHP public API in 7+ only

Could you please explain this a bit more? What you mean "in 7+ only"?

https://github.com/php/php-src/blob/PHP-5.5/Zend/zend.h#L294

remicollet · 2017-06-20T04:31:58Z

Could you please explain this a bit more? What you mean "in 7+ only"?

There is no ZEND_API, so not public, not usable (may me different according of compiler default visibility)

Use distro packages ;)

remicollet · 2017-06-20T05:01:12Z

BTW, the fix is trivial
sed -e s/zend_error_noreturn/zend_error/ ...

sergeyklay · 2017-06-20T06:06:28Z

@remicollet

BTW, the fix is trivial
sed -e s/zend_error_noreturn/zend_error/ ...

So can I not rush with patch for 3.2.0 and do it in 3.2.1?

remicollet · 2017-06-20T06:17:52Z

So can I not rush with patch for 3.2.0 and do it in 3.2.1?

Your project, your priority, your choice.

BTW, I was able to build 3.2.0 for 5.5, 5.6, 7.0 and 7.1 (haven't try 7.2 yet), other users could encounter the same issue, or segfault at runtime, which is IMHO worse...

Perhaps everybody have switched to 7+, and you can wait for other reports

sergeyklay · 2017-06-20T06:24:50Z

Sure. But actually, it was important for me to hear exactly your opinion, because you maintain package repos for RPM based distros. Is this prevent you to release Phalcon 3.2.0 for PHP 5.x or not?

remicollet · 2017-06-20T06:29:35Z

Is this prevent you to release Phalcon or not?

No, as I patch sources to drop zend_error_noreturn usage

Notice: zend_error_noreturn does exactly the same than zend_error, only exists to avoid compiler warnings

void zend_error_noreturn(int type, const char *format, ...) __attribute__ ((alias("zend_error"),noreturn));

remicollet · 2017-06-21T07:31:32Z

Test build: version 3.2.0 using zephir 0.9.9 => OK.

Jurigag · 2017-06-21T10:26:24Z

Great, soe we should release 3.2.1 right now imho.
