php-ext-snappy's Introduction

Snappy Extension for PHP

This extension allows Snappy.

Documentation for Snappy can be found at » http://google.github.io/snappy/.

Build from sources

git clone --recursive --depth=1 https://github.com/kjdev/php-ext-snappy.git
cd php-ext-snappy
phpize
./configure
make
make install

To use the system library

./configure --with-snappy-includedir=/usr

Distribution binary packages

Fedora / CentOS / RHEL

RPM packages of this extension are available in » Remi's RPM repository and are named php-snappy.

Configuration

php.ini:

extension=snappy.so

Function : `snappy_compress()`

string snappy_compress( string $data )

parameters

data:

The data to compress.

return values

The compressed string or FALSE if an error occurred.

Function : `snappy_uncompress()`

string snappy_uncompress( string $data )

parameters

name:

The data compressed by snappy_compress().

return values

The original uncompressed data or FALSE on error.

Example

$compressed = snappy_compress('Compress me');

$uncompressed = snappy_uncompress($compressed);

echo $uncompressed;

Troubleshooting

Ubuntu / OSX

Snappy requires C++ and therefore might require for you to install the g++ or build-essential package.

If you get an error about "this file requires compiler and library support" or compilation errors on OSX, you need to enforce the compilation with -std=c++11 flag:

export CXXFLAGS=-std=c++11
phpize
./configure
make

php-ext-snappy's Issues

Building fails on PHP8 on MacOS

I'm not certain if this package just hasn't been updated to support PHP8 yet, or if it's a problem with my machine/configuration. The output of make is:

/bin/sh /Users/troy/php-ext-snappy/libtool --mode=compile cc -I. -I/Users/troy/php-ext-snappy -I/Users/troy/php-ext-snappy/include -I/Users/troy/php-ext-snappy/main -I/Users/troy/php-ext-snappy -I/usr/local/Cellar/php/8.0.1_1/include/php -I/usr/local/Cellar/php/8.0.1_1/include/php/main -I/usr/local/Cellar/php/8.0.1_1/include/php/TSRM -I/usr/local/Cellar/php/8.0.1_1/include/php/Zend -I/usr/local/Cellar/php/8.0.1_1/include/php/ext -I/usr/local/Cellar/php/8.0.1_1/include/php/ext/date/lib -I/Users/troy/php-ext-snappy/snappy  -DHAVE_CONFIG_H  -g -O2    -c /Users/troy/php-ext-snappy/snappy.c -o snappy.lo

APCu serialization support

Would be great to allow build it with apcu support (like igbinary doing) to allow use snappy as serialization for it

I can't build it for php7.3

PHP 7 Support

Hi @kjdev,

Is this extension compatible to PHP 7? Does it need to be fixed or ready for PHP 7? If it needs to be fixed, do you manage to do it? and ETA?

Thanks

Can't install it on Windows

Ubuntu
I have tried as ReadMe instructed. In other words, I have made so file and copied into relevant directory that contians other .so files. And I made snappy.ini file in /etc/php/7.2/conf.d and 20-snappy.ini file /etc/php/7.2/mods-available.
After that, I have tried to composer install again. But still it says my system has no php extension snappy.
Windows
Is there no solution for this extension. I can't find any solution here.

snappy_uncompress: allow capping the max output length

Currently there is no easy way to set the max decompressed size using this extension. This means that snappy can be used for zip bombing attacks if it's used to compress user input.

A $max_decoded_len parameter, which limits the max size of the decompressed payload similar to zlib_decode(), would be nice to have.

How do I fix vulnerability in image. Vulnerability Details : CVE-2009-3736

Vulnerability Details : CVE-2009-3736

ext-snappy config.m4 AC_LANG([C++]) causes it to fail to compile inline

Is it better to use AC_LANG_PUSH and AC_LANG_POP when compiling related C++ files?

Because I was trying to add the snappy extension to static-php-cli and discovered that the snappy extension's AC_LANG([C++]) would cause other extensions and autoconf AC_CHECK_LIB to generate incorrect results when compiled inline.

A reproducible example is that when I was compiling Swoole and snappy inline on the macOS platform, I found that the content of conftest.c for checking kqueue in php-src/configure changed to namespace conftest{.

add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
use the `-Wl,-rpath -Wl,LIBDIR' linker flag
have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for

more information, such as the ld(1) and ld.so(8) manual pages.

Build complete.
Don't forget to run 'make test'.

Merges fom 29.5. not working with build-essential package?

Hi,

we are running snappy with build-essential installed on ubuntu:16.04 for some while now. This setup is not working anymore with the new merges from yesterday (29.05.).

We get the following error:

#error This file requires compiler and library support \
Step #0: /usr/include/c++/5/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

What do we need to change? do we need more than the build-essential package? Can we provide more information on that issue?

Kind regards,
Christian
