Re: What is this error means?

[Ellery Leung]

Here are a workaround of this issue:

On line 382 of SolrPhpClient/Apache/Solr/Service.php, I change to:

while(true){
        $str = file_get_contents($url, false, $this->_postContext);
        if(empty($str) == false){
                break;
        }
}

$response = new Apache_Solr_Response($str, $http_response_header,
$this->_createDocuments, $this->_collapseSingleValueArrays);

As I found that, for some strange reason on Windows, when you post some data
and add index, Solr may not be able to receive it.  Therefore I added an
infinitive loop and if it does not receive any response ($str is empty), we
post it again.

Side effect: when I open the window console to see it, sometimes it will
prompt:

Failed to open stream: HTTP request failed!

I haven't researched it yet, but the index is built successfully.

Hope it helps someone.
