Missing support for php 7.2

[gergnz]

I'm not able to use the php7 branch to build against php7.2. While the build completes, the shared object can't be loaded due to a missing symbol, which looks to have changed between php 7.1 and php 7.2: strpprintf

[sodabrew]

See #11 for instructions on how to compile – Both PHP 7.1 and 7.2 are supported by the underlying modules, however binaries are provided by Amazon only for PHP 7.0 at this time.

[gergnz]

I've tried and it's not working. (see my comments re missing symbol strpprintf). It looks like this has changed in zend, and my C isn't good enough to understand what's going on.

Also this comment (#11 (comment)) suggests that it isn't working for others.

I just managed to install PHP 7.2 on ubuntu 16.04 and compile the client based on libmemcached 1.0.8. In case you need the binary to get unblocked, here it is. Let me know if this works for you or not.

[markhughes]

@QuChen88 tested on PHP Version 7.2.5-1+ubuntu16.04.1 and it seems to be connecting and doing basics. Will have a better play later.

[agaleski]

On PHP 7.2.9-1+ubuntu16.04.1+deb.sury.org+1 via ppa:ondrej/php copy the amazon-elasticache-cluster-client.so from @QuChen88 (#19 (comment)) to /usr/lib/php/20170718/ so php7.2-fpm can find it

[elyobo]

Part way through upgrading to PHP 7.2 on Amazon Linux and 💣 💥 turns out that AWS doesn't provide a client yet :-/

[elyobo]

That said, @QuChen88's version above does seem to work for me on the latest Amazon Linux; any news when an "official" version would be available?

[elyobo]

Addendum, we're seeing a lot of logs with Unknown: using touch command with binary protocol is not recommended with libmemcached versions below 1.0.18, please use ascii protocol or upgrade libmemcached with @QuChen88's package above. @QuChen88, given the comments on php-memcached-dev/php-memcached#310 and php-memcached-dev/php-memcached#322 it seems like compiling against a newer libmemcached is probably required to support the default PHP7 behaviour (lazy write enabled).

@gergnz you should close this issue for the best answer of @QuChen88

[powrsurg]

I would say this should be verified on systems besides Ubuntu before closing.

[sodabrew]

As the maintainer of the php-memcached module on which this work is based, I must urge against using older versions of libmemcached with known bugs and deficiencies. What is the problem that is blocking the AWS modifications to libmemcached 1.0.18 from being used here?

[gergnz]

@sodabrew, can you advise on these upstream changes please?

[sodabrew]

Read five comments back, the error message says to use an updated library to avoid a specific bug. That text is meant to be as clear as possible in people’s error logs.

is there an aws elastic client memcached for PHP 7.2 in amazon linux?

Read my comment above. @QuChen88 comment worked for me.

[elyobo]

It "works" for certain values of "works"; the stream of warnings reporting about Unknown: using touch command with binary protocol is not recommended with libmemcached versions below 1.0.18, please use ascii protocol or upgrade libmemcached is concerning and @sodabrew's (maintainer of the upstream php-memcached) comments also suggest that this issue is not properly resolved.

To resolve this

• update libmemcached
• do a proper release with it, not just a comment in an issue
• have it downloadable through the AWS console as per other releases

Read my comment above. @QuChen88 comment worked for me.

@QuChen88 answer is for debian OS. what about amazon linux?

[elyobo]

My comments above are from using it on Amazon Linux @liaogz82; it installs and appears to work, but has a stream of warnings in the logs and the impact of that isn't clear to me.

[mosesliao]

@elyobo how do you get the logs? I managed to get it working and on the surface seems to be ok

[elyobo]

Wherever your PHP logs go, and presumably also dependent on your error_reporting settings.

How did you manage to compile it? Where's the source-tree with the modifications you needed to make, and where are the compile parameters documented? Thank you.

[QuChen88]

@Seegras IIRC, I compiled it following the instructions I had in the README.markdown file. I launched an EC2 instance from AWS console using the standard Ubuntu AMI.

[WillyYeh]

Many thanks to @luishdz1010. I followed your Dockerfile and build my own RPM and PEAR package.
Follow these steps to build our own RPMS and PEAR package.

• Prepare the building environment.
  Create a development environment which are same as production environment. For example, m5.medium in EC2. And limit the max hosts to 1 if your are using Elastic Beanstalk.

export HOME=/home/ec2-user
export PKG_CONFIG_PATH=/usr/lib64/pkgconfig
sudo yum -y install rpm-build java-1.8.0-openjdk
mkdir -p ~/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
echo '%_topdir %(echo $HOME)/rpmbuild' > ~/.rpmmacros
echo "%packager You <your@email>" >> ~/.rpmmacros
mkdir ~/src

• Build libmemcached RPM
  Create your own libmemcached.spec before running below commands.

cd ~/src
sudo yum install -y libevent-devel
wget https://github.com/awslabs/aws-elasticache-cluster-client-libmemcached/archive/v1.0.18.tar.gz
tar zxf v1.0.18.tar.gz
cd aws-elasticache-cluster-client-libmemcached-1.0.18 && mkdir BUILD && cd BUILD
../configure --prefix=/usr --libdir=/usr/lib64 --with-pic && make && make DESTDIR=/home/ec2-user/rpmbuild/SOURCES/libmemcached-1.0.18 install
cd ~/rpmbuild/SOURCES
rm libmemcached-1.0.18/usr/lib64/*.la
tar zcf libmemcached-1.0.18.tar.gz libmemcached-1.0.18
sed -i '/^%defattr/,$d' ../SPECS/libmemcached.spec && echo -e "%defattr(-,root,root,-)" >> ../SPECS/libmemcached.spec && find libmemcached-1.0.18 ! -type d ! \( -path 'libmemcached-1.0.18/usr/include/*' -o -path 'libmemcached-1.0.18/usr/lib64/pkgconfig/*' -o -path 'libmemcached-1.0.18/usr/share/man/man3/*' -o -path 'libmemcached-1.0.18/usr/share/aclocal/*' -o -path 'libmemcached-1.0.18/usr/lib64/*' \) -o -path 'libmemcached-1.0.18/usr/lib64/*.so.*' -o -path 'libmemcached-1.0.18/usr/lib64/*.a' | sed 's/^[^\/]*\//\//g' >> ../SPECS/libmemcached.spec && echo -e "\n%files devel\n%defattr(-,root,root,-)" >> ../SPECS/libmemcached.spec && find libmemcached-1.0.18 ! -type d \( -path 'libmemcached-1.0.18/usr/include/*' -o -path 'libmemcached-1.0.18/usr/lib64/pkgconfig/*' -o -path 'libmemcached-1.0.18/usr/share/man/man3/*' -o -path 'libmemcached-1.0.18/usr/share/aclocal/*' -o -path 'libmemcached-1.0.18/usr/lib64/*.so' \) | sed 's/^[^\/]*\//\//g' >> ../SPECS/libmemcached.spec
vi ../SPECS/libmemcached.spec
rm -rf libmemcached-1.0.18

sudo rpm -Uvh ../RPMS/x86_64/libmemcached-1.0.18-1.amzn1.x86_64.rpm ../RPMS/x86_64/libmemcached-devel-1.0.18-1.amzn1.x86_64.rpm

• Build ElastiCache Cluster Client for PHP PEAR package.
  Download AmazonElastiCacheClusterClient-1.0.0-PHP70-64bit.tgz from AWS ElastiCache Client for PHP webpage. Untar it and then change folder name to AmazonElastiCacheClusterClient-2.0.3 if you like. Remember you have to update the md5 of modules/memcached.so in package.xml.

cd ~/src
sudo yum install -y cyrus-sasl-devel php72-pecl-igbinary-devel
git clone https://github.com/awslabs/aws-elasticache-cluster-client-memcached-for-php.git && cd aws-elasticache-cluster-client-memcached-for-php/ && git checkout php7
phpize
./configure --disable-memcached-sasl --enable-memcached-igbinary --with-libmemcached-dir=/usr && make
tar zxf <somewhere>/AmazonElastiCacheClusterClient-2.0.3-PHP72-64bit.tgz
cp modules/memcached.so AmazonElastiCacheClusterClient-2.0.3/amazon-elasticache-cluster-client.so
vi package.xml
rm AmazonElastiCacheClusterClient-2.0.3-PHP72-64bit.tgz && tar zcf AmazonElastiCacheClusterClient-2.0.3-PHP72-64bit.tgz package.xml AmazonElastiCacheClusterClient-2.0.3/

Now you can install by pecl7 install AmazonElastiCacheClusterClient-2.0.3-PHP72-64bit.tgz
PS: You may get an error which related to /usr/share/pear7/Archive/Tar.php
Just run below command:
sed -i '639s/$v_att_list = & func_get_args();/\\$v_att_list \\&= func_get_args();/' /usr/share/pear7/Archive/Tar.php

We are moving to Ubuntu 18.04, and I was surprised to see the version for PHP 7.2 not downloadable directly from AWS yet. Considering PHP 7.2 was released over 1 year ago, and is the standard in Ubuntu's newest LTS, I am hoping it is coming soon. Are there plans to make this available for download, or provide instructions for compiling in 18.04? I have tried several different ways of compiling in 18.04 and I haven't had much success yet.

[ninjada]

Second jswinborne's comments. Been waiting for what seems like forever for this -- compilings not the end of the world but have had it cause a couple of hiccups with my moves to Amazon Linux 2.

I would have thought the amazon-linux-extras option would have been perfect for this? Given its intended ease of use is somewhat logically questionable in the first place.

[elyobo]

@QuChen88 is this project officially supported by AWS? It's in the awslabs account and you're a member of the Amazon Web Services org, so I've been assuming so, but given the lack of any activity in supporting the PHP versions available on AWS's own "Amazon Linux" distro I may have misunderstood?

[nkhine]

i managed to get it working under docker https://github.com/nkhine/centos-nginx-php72-fpm/blob/master/Dockerfile

you can download the client for 7.2 from https://eu-west-1.console.aws.amazon.com/elasticache/home?region=eu-west-1#client-download:

AWS Support just sent this:

Coming back to your question with related to the PHP client version, Amazon officially provides the Elasticache Memcached Cluster Client PHP 7.0 and 7.2 now. The client version is available to download from the ElastiCache console under the section ElastiCache cluster clients. Unfortunately, I do noticed that the repo link provided do not get properly and apologize for the confusion it has been caused to you.

Could you please check and update the client version to 7.2 to match your current PHP version. Once you have downloaded the required client version, please install the latest version of the ElastiCache PHP client. Please note that to update the php-memcached installation you need to remove the previous installation of the Memcached extension for PHP and install the new ElastiCache php-memcached extension as described here [2-3].

If you need any further assistance, please don't hesitate to reply to this case, I will be happy to assist you.

[QuChen88]

PHP 7.2 is now supported and downloadable from AWS console.

[bensebborn]

@QuChen88 is this 7.2 .so file compiled against libmemcached 1.0.8 or 1.0.18?

[yzhaon]

@QuChen88 is this 7.2 .so file compiled against libmemcached 1.0.8 or 1.0.18?

The PHP 7.2 memcached client is now compiled against libmemcached 1.0.18.

Please update if you had an older version.

[rmanidev]

I have downloaded the latest version, libmemcached 1.0.18 . I have an issue on this after resetserverlist() the Memcached object is not supported properly. Anybody known this error?
Sample Code is :
`$m = new \Memcached($persistent_id);

$m->setOption(Memcached::OPT_LIBKETAMA_COMPATIBLE, true);

var_dump($m->addServer($host, $port, $weight));
echo "
server List: ";var_dump($m->getServerList());
echo "
Reset Server Status: ";var_dump($m->resetServerList());
echo "
Add Server Status: ";var_dump($m->addServer($host, $port, $weight));
echo "
Server List: ";var_dump($m->getServerList());`

Result is:
Reset Server Status: bool(true)
Add Server Status: bool(false)
Server List: array(0) { }

After resetServerList() function is not working properly. But the same code is working correctly in php Memcached library.

Please update anyone know this error.
