PHP Ice_initialize() hangs

[xorax]

Hi,

My situation: FreeBSD 8.0; Ice-3.4.1 compiled from sources; Python binding works fine.

But in PHP any script with ICE hangs on ice_initialize() call.
No error/warning/notice messages.

I understand that FreeBSD is not supported. Nevertheless, maybe someone would have some ideas.

Thanks!

Hi,

You should attach to the PHP process with the debugger and get a stack trace of the process when it hangs. This might give you some clues on the origin of the hang.

Cheers,

Do you mean high-level debugger like xdebug or some low-level debugger? To use the latter my PHP and ICE have to be compiled in debug mode, as far as I understand.

Hi,

I mean a debugger such as gdb. Yes, it's best if the programs are compiled with debug information but on most platform you can also see some basic symbol information (function names) for programs compiled without debug.

It seems like execution freezes on the following:

As far as I understand, it's about FreeBSD threads implementation. Are there any chances to workaround it?

Hi,

I'm afraid there's isn't enough information from this stack to figure out where the problem could come from... You'll need to re-compile Ice with debug information and run the test suites to see what works and what doesn't.

Hi Ivan,

is this on i386 or on amd64 (I had similar issues in the past and could solve them somehow, can't recall exactly how right now). Also, are you using IceSSL?

A very possible issue is that your libphp is not linked against libthread. I contributed to a thread showing that problem a while ago, see: php5-Ice on FreeBSD 7.1

As a result of this thread (at least I want to think so) the php5 port has a new configuration option now.

So you should make sure to select the LINKTHR when installing lang/php5

(e.g. cd /usr/ports/lang/php5; make config; make install).

See the attached screenshot (highlighted option). This should fix the issue.
