FFIMe Uncaught PHPCParser\Error: Syntax error, unexpected IDENTIFIER(int_least8

Hi @bwoebi

Attempting to use Redis's https://github.com/redis/hiredis library, I'm getting the following error.

PHP Fatal error:  Uncaught PHPCParser\Error: Syntax error, unexpected IDENTIFIER(int_least8_t), expecting ',' or ';' on line 395 in ~/hiredis/vendor/ircmaxell/php-c-parser/lib/ParserAbstract.php:236

The hiredis.h file itself doesn't include any int_least8_t yet one of its dependencies stdint.h which is a glibc-headers package included header.

I guess the part of interest in the stdint.h file is the following.

/* Small types.  */

/* Signed.  */
typedef __int_least8_t int_least8_t;
typedef __int_least16_t int_least16_t;
typedef __int_least32_t int_least32_t;
typedef __int_least64_t int_least64_t;

/* Unsigned.  */
typedef __uint_least8_t uint_least8_t;
typedef __uint_least16_t uint_least16_t;
typedef __uint_least32_t uint_least32_t;
typedef __uint_least64_t uint_least64_t;

This specific parser error happens when typedef is followed by a not defined identifier.

On my linux system /usr/include/x86_64-linux-gnu/bits/types.h defines __int_least8_t (which is included from <stdint.h> on my system).

Does grep -r __int_least8_t /usr/include find anything for you? Is <bits/types.h> included in your stdint.h?

Aug 23 '22 16:08 bwoebi

@bwoebi yes, <bits/types.h> included in my stdint.h

grep -r __int_least8_t /usr/include

/usr/include/bits/types.h:typedef __int8_t __int_least8_t;
/usr/include/stdint.h:typedef __int_least8_t int_least8_t;

@bwoebi also experienced the same attempting to use https://github.com/facebook/rocksdb/blob/main/include/rocksdb/c.h

Sorry for the delay, yes, I can reproduce it and am looking into it.

Aug 26 '22 18:08 bwoebi

The problem is that these macros are gcc predefined macros, concretely it does not find __INT_LEAST8_TYPE__ here.

If you check echo | gcc -E -xc -v -dM - you'll find these there... Added more of them to php-c-parser. hiredis works now for me.

@bwoebi Yeah everybody needs a downtime, eventually :)

I got the following after the update...

For the following code...

<?php
require_once __DIR__ . '/vendor/autoload.php';
(new FFIMe\FFIMe('/usr/lib64/libhiredis.so.1.0.0'))
    ->include('/usr/include/hiredis/hiredis.h')
    ->codeGen('hiredis\\hiredis', __DIR__ . '/hiredis.php');
require __DIR__ . '/hiredis.php';

I am getting...

Ah, I see, you have 1.0.0, which gets interpreted as number :-D (I had 1.0.3-dev which was not recognized as number)

Fixed.

😀 ah okay. Will test it right away.

Aug 28 '22 15:08 cayolblake

@bwoebi Any luck here?

Aug 31 '22 18:08 cayolblake

I will check it out (yes, I can reproduce it), but given it's only warning, I wasn't looking at it with high priority.

Sep 01 '22 10:09 bwoebi

@bwoebi yeah I understand, but its blocking the possibility of usage.

Thank you anyways.

Sep 01 '22 17:09 cayolblake

@cayolblake I'm working on it - it needs recursively resolving all referenced shared libraries for all supported targets (ELF and MachO), which is a tiny bit bigger feature, please be a bit patient :-)

Sep 03 '22 11:09 bwoebi

@bwoebi Yeah I understand :)

Having this feature, I'm planning to write a number of blog posts to promote FFIMe and showcase its usage and how far it goes into killing the barrier of entry for developing an extension for any native library 🚀

Will standby for whenever it's done to test 💪

Sep 03 '22 12:09 cayolblake

@cayolblake I've just added recursive symbol resolution for shared objects. There should be a lot less warnings now.

Sep 07 '22 19:09 bwoebi

Thanks @bwoebi

Will have it tested shortly and update you.

👍👍

Sep 07 '22 23:09 cayolblake

@cayolblake What have you tested that on? I've tried with your hiredis reproducer, and it only gave me the very last line.

Sep 12 '22 18:09 bwoebi

@bwoebi same hiredis code here.

I also verified I got the latest update. Tried in a new scratch project also same results.

Anyway to debug and generate you something useful?

Sep 12 '22 21:09 cayolblake

Basically I would probably need debug information around https://github.com/ircmaxell/php-object-symbolresolver/blob/master/lib/ELF/ObjectFile.php#L78

Does it find all the self::getSharedSearchPaths()? (see "shared library search path" section of your /usr/lib64/ld-linux-x86-64.so.2 --help output (or where your dynamic linker resides)) Is it able to find libc in these paths? Does it find libc in the dynamic section (i.e. $dependencies array)?

Sep 12 '22 23:09 bwoebi

@bwoebi So, self::$sharedLibrarySearchDirectories was hardcoded to /lib, and /usr/lib.

I changed that to /lib64, and /usr/lib64, which is basically what's on any RedHat/Fedora/openSUSE...etc. 64bit systems, and reran the reproducer code, and it worked! Only giving out the last warning line!!

Not sure why the hardcoding of things, however I guess this would definitely lead to multiple issues moving forward in many other systems/distros probably.

Is it possible to acquire such details in a dynamic way to avoid relying on pre-assumed paths or variables?

Sep 13 '22 15:09 cayolblake

There is a bit hardcoding into the linker itself - /lib and /usr/lib are hardcoded on Ubuntu - for everything else I'm looking at /etc/ld.so.conf, but possibly this is differently on your distro?

What's the output of cat /etc/ld.so.conf (and if has includes, the included files, e.g. cat /etc/ld.so.conf.d/*)?

Sep 13 '22 17:09 bwoebi

@cayolblake But anyway, added it for now just as is: https://github.com/ircmaxell/php-object-symbolresolver/commit/778bf45448f901a97c9875eb912104a311283aea

What's the output of cat /etc/ld.so.conf (and if has includes, the included files, e.g. cat /etc/ld.so.conf.d/*)?

Nothing in the file, and the dir as well is empty.

Thanks for the fix. I goes these covers most, if not all the possible standard locations.

May be think of exposing this as a config for anybody else wanna ping you special location? 🤔

I think that makes sense, added: https://github.com/ircmaxell/php-object-symbolresolver/commit/dfe1b1aa6c15b198bdef50fff8485e98e89f2a09.

I guess we can close this issue now, then?
