Binary protocol is broken

[ziadloo]

I've been having trouble using binary protocol in very simple scenarios. For instance:

<?php
$mc = new \Memcached();
$mc->setOption(\Memcached::OPT_BINARY_PROTOCOL, true);
$mc->addServer("127.0.0.1", 11211);

$mc->touch("key", time() + 600);
$touchResult = $mc->getResultCode();
$mc->set("key", 1, time() + 600);
$setResult = $mc->getResultCode();

echo "<pre>";
echo "Touch result: $touchResult\n";
echo "Set result: $setResult\n";
echo "</pre>";

The first run outputs:

Touch result: 16 [RES_NOTFOUND]
Set result: 0 [RES_SUCCESS]

And the second run forth will output:

Touch result: 0 [RES_SUCCESS]
Set result: 5 [RES_WRITE_FAILURE]

Here are my system's configurations:

• Ubuntu 12.04 64bit
• PHP 5.3.14
• memcached 2.1.0 (PECL module)
• libmemcached 1.0.8
• Memcached sever 1.4.13

I've been able to duplicate this issue, I've also had issues with Touch command that's why I found this report.

Problems here too:

         Text protocol
         php > $m = new \Memcached();
         php > $m->addServer('localhost', 11211);
         php > $m->add('test', 4, null);
         var_dump($m->get('test'));
         int(4)
         php > $m->increment('test', 4);
         php > var_dump($m->get('test'));
         int(8)

         Binary protocol:
         php > $mb = new \Memcached();
         php > $mb->addServer('localhost', 11211);
         php > $mb->setOption(\Memcached::OPT_BINARY_PROTOCOL, true);
         php > $mb->add('test2', 4, null);
         php > var_dump($mb->get('test2'));
         int(4)
         php > $mb->increment('test2', 4);
         php > var_dump($mb->get('test2'));
         bool(false)

Can't replicate any of these problems with

php-memcached 2.1.0
libmemcached 1.0.17
memcached 1.4.15

[eduardosoliv]

I updated my versions to this and solved my problem with increment:

memcached 1.4.15

memcached support => enabled
Version => 2.1.0
libmemcached version => 1.0.8
Session support => yes
igbinary support => no
json support => no

[ziadloo]

Here are my new configurations and the problem still remains:

• Ubuntu 12.04 64bit
• PHP 5.3.14
• memcached 2.1.0 (PECL module)
• libmemcached 1.0.8
• Memcached sever 1.4.15
• Session support yes
• igbinary support no
• json support no

Considering the same code above, the first run outputs:

Touch result: 16 [RES_NOTFOUND]
Set result: 0 [RES_SUCCESS]

And the second run forth will output:

Touch result: 0 [RES_SUCCESS]
Set result: 5 [RES_WRITE_FAILURE]

[eduardosoliv]

My contribution (my config is already above), I get exactly same results:

Touch result: 16
Set result: 0

Touch result: 0
Set result: 5

touch seems to be broken with binary protocol for some reason, ignores timeout

[ziadloo]

@mkoppanen would you please state the version in which is issue has been resolved?

[mkoppanen]

I am testing with libmemcached 1.0.17

[mkoppanen]

Also, if you look at the following: https://travis-ci.org/php-memcached-dev/php-memcached the tests/gh_77.phpt seems to be pass with all libmemcached versions.

@mkoppanen I've ran the test on my server (which I've been having this problem with) and the test failed:

bool(false)
bool(false)

Server info:

Linux 2.6.34-xen-r5 SMP Sun Jan 1 22:47:41 EST 2012 x86_64 Intel(R) Xeon(R) CPU E5430 @ 2.66GHz GenuineIntel GNU/Linux

PHP 5.4.13--pl0-gentoo (cli) (built: Aug 6 2013 17:39:08)

Memcached section in: php -i

memcached
memcached support => enabled
Version => 2.1.0
libmemcached version => 1.0.14
Session support => yes
igbinary support => no
json support => no

The highest version of libmemcached in the Gentoo repos is 1.0.14, and the ebuilds I've found for libmemcached, 2.1.0 won't compile against so I really don't have a choice right now. :(

[mkoppanen]

Which version of memcached?

[mkoppanen]

Added 1.0.14 to builds: https://travis-ci.org/php-memcached-dev/php-memcached/builds/12748482

Looks like the test fails on 1.0.14 and passes on higher versions
