[PCBC-212] make persistent connections on by default

Sun, 17 Mar 2013 13:40:10 -0500

I think it's time to make the switch.

See:

[PCBC-204] Persistent connections should be indexed on server list contents, not their order.

Thu, 14 Feb 2013 09:44:40 -0600

In the current state, we simply treat the connection parameter as a string.

An example use case may be of several clients trying to load-balance between various entry points nodes (EPTs). Such a strategy ensures that they aren't all hitting the same node for configuration requests.

However when attempting to use this in conjunction with persistent connections, we have the consequence that each permutation of the "Server List" is treated as a separate key when using persistent connections; therefore something like:

$base_list = array("1.1.1.1", "2.2.2.2", "3.3.3.3", "4.4.4.4");

for ($i = 0; $i < 1000; $i++) {
$cur_list = $base_list;
shuffle($cur_list);
$cb = new Couchbase($cur_list, "", "", "", true);
$cb->set("foo", "bar");
// other operations
}

In a nutshell, this code has a "base" set of four servers. In the "normal" initialization code, the list is copied and then shuffled around, so that the first server in the list is always something else. Since the first server in the list ends up becoming the EPT (unless the server is down, in which case the next node is used, etc.) this enables some kind of cheap load balancing.

However this also means the order of the array is different, which means the "canonical connection key" is different, which means that when considering whether an existing connection is available, a new one is created. Since we have 4 servers in the list, there is a potential of having 4*4=16 different client objects per process. These objects will never die.

The solution is then to "deconstruct" the connection string in such a way that the server list itself is always alphabetically sorted. The effective list (When actually connecting) will remain the same, but for indexing purposes, it shall be sorted.

[PCBC-181] The documentation is wrong for get() in couchbase-api.php

Fri, 18 Jan 2013 07:31:21 -0600

I just discovered this while fixing a bug in Basement.

The $cas variable callback is not working on get() but works on getMulti().

Simple example:

Works:
$client->set("foo", "bar");
$cas = null;
var_dump($client->getMulti(array("foo"), $cas));
var_dump($cas);

array(1) {
  ["foo"]=>
  string(3) "bar"
}
array(1) {
  ["foo"]=>
  string(20) "11699665754086047744"
}

Doesn't work:
$client->set("foo", "bar");
$cas = null;
var_dump($client->get("foo", $cas));
var_dump($cas);

string(3) "bar"
NULL

The doc gets returned properly, but the cas value is not set. Also, when you set $cas to "" or false (not null), then it complains with a dubios error:
Warning: Couchbase::get() expects parameter 2 to be a valid callback, no array or string given in /Users/michael/Webserver/basement-test/index.php on line 10
Note that its a warning and not an exception on the OOP interface!

[PCBC-175] released bundle should contain the example php ini file and the couchbase api file

[PCBC-174] Create a php file with "javadoc-style" comments describing the api

Thu, 3 Jan 2013 00:54:37 -0600

[PCBC-161] update tutorial to be based on sample database

Fri, 10 May 2013 02:44:45 -0500

Update the PHP sample with a simple app that covers three things:
CRUD (just get/set is fine)
JSON (PHP has this built in)
querying views

Optionally, do this with Twitter Bootstrap (as Michael and Sergey are using). Not required. It should be a webapp though.

This should pick up after the getting started guide which Karen is updating.

[PCBC-133] connection options needs updating in 1.1 docs

Mon, 18 Feb 2013 10:46:20 -0600

For 1.0.5, we updated the connection options about redundant connections. We need to bring those changes over to the 1.1. documentation as well.

[PCBC-130] Remove mention of pecl-memcache and pecl-memcached from http://www.couchbase.com/develop

Tue, 16 Apr 2013 11:21:00 -0500

Is this docs or client library?

Anyway, a customer somehow missed the big "PHP 1.0" link at the top of the page and thought that he had to use pecl-memcache*. let's remove those now that we have native PHP support.

[PCBC-126] Tests: Make view helper script in PHP

Tue, 12 Mar 2013 14:53:58 -0500

It currently uses a short perl script to create the view and design doc. This should be done in PHP if possible

[PCBC-96] Create compatibility layer for flags in PHP

Sun, 16 Dec 2012 11:11:37 -0600

In ~~PCBC-78~~, we'd added a simple workaround to working with JSON from multiple languages. We need a more elegant approach though, and that'd need to consider standardizing flags or some other approach. This issue will track that need.

[PCBC-24] deploying to download locations directly from CI

Sun, 16 Dec 2012 11:11:37 -0600

The idea here is that non-releases should automatically upload deploy to one location, and releases should automatically deploy to a different location.
