Error 500 while reading daemon's response
From jsonRPCClient.php, line 132:
if ($fp = fopen($this->url, 'r', false, $context)) {
$response = '';
while($row = fgets($fp)) {
$response.= trim($row)."\n";
}
$this->debug && $this->debug.='***** Server response *****'."\n".$response.'***** End of server response *****'."\n";
$response = json_decode($response,true);
} else {
throw new Exception('Unable to connect to '.$this->url);
}
the exception is thrown by simply invoking $ php5 index.php from the console.
The output I get is;
$ php5 index.php
PHP Warning: fopen(http://...@localhost:8332): failed to open stream: HTTP request failed! HTTP/1.1 500 Internal Server Error
in /var/www/pluscoin/jsonRPCClient.php on line 132
<!DOCTYPE html>
<html lang='en'>
<head>
<meta charset='utf-8'>
... /* etcetera */
The credentials are set and the daemon is running. Fore reference, with curl I get:
$ curl http://...@localhost:8332
{"result":null,"error":{"code":-32700,"message":"Parse error"},"id":null}
The getbalance lines from index.php are modified as suggested here.
I'll investigate this problem later when I have bitcoindset up to test. I'm not sure what has changed recently in Bitcoin to break this, as the JSONRPC should still be the same.
Update: Today I discovered Bitcoin has reached 60GB. That makes it expensive to spin up a server. Do you know if this affects other coins (ones with a less ridiculous sized blockchain?) such as Litecoin, Dogecoin or Namecoin?
After minimal debugging I found that this error 500 is simply due to header.php calling $nmc->walletlock() with an unencrypted wallet. AFAIK this is not supported by bitcoind and causes the error response. Apart from this, no actual disruption seems to occur at all.
