Description: ------------ the new readLeftOver feature in Net_Server 1.0.0 is causing problems with HTTP_Server when using (at least) the sequential driver. The problem that is occuring is the "end" of a previous request is appearing in the beginning of the next request and causing HTTP_Server to fail to find the initial GET line of the HTTP request as any trailing \r\ns from the previous request appear in the beginning of the new un-related request. What is the intended reasoning for the readLeftOver feature?? And shouldn't it be cleared upon client disconnect?

Patch to fix of of the underlying issues. The length of readEndCharacter (which with HTTP_Server is 4 characters not 1). was not taken into account when appending the endCharacter to $data. also when checking for leftover parts, readEndCharacter was not taken into account at all. --- Net_Server-1.0.0/Server/Driver.php.orig 2006-06-26 12:57:38.000000000 -0400 +++ Net_Server-1.0.0/Server/Driver.php 2006-06-26 12:57:49.000000000 -0400 @@ -232,8 +233,8 @@ if ($posEndChar === false) { $data .= $buf; } else { - $data .= substr($buf, 0, $posEndChar + 1); - if ($posEndChar < strlen($buf)) { + $data .= substr($buf, 0, $posEndChar + strlen($this->readEndCharacter)); + if (($posEndChar + strlen($this->readEndCharacter)) < strlen($buf)) { $this->_readLeftOver = substr($buf, $posEndChar + 1); } break;

readLeftOver is needed when the sever gets hammered with some 100 requests/second. Then it occurs that two requests get delivered to the same connection, making it necessary to split them. I'm about to fix it, but it's not as easy as your patch does it.

Thanks. CVS HEAD works. When the 1.0.1 release gets out I can finally drop all my "kludges, patches and workarounds" in my code.
