Hi @Greg-DB
Thank you for your quick response.
>>the name and version number of the platform and SDK/library you are using, if any
I'm not using SDK/library, I have made a curl function to send/receive the data from Dropbox API. I'm using the PHP Stream Wrapper class to upload and download the backup file. Below is the code snippet of the curl function
function __curl($url, $headers = '', $filepointer = '', $upload_size = 0, $post = '', $download_file = '', $ignore_errors = 0, $retry = false){
global $error, $l;
// Set the curl parameters.
$ch = curl_init($url);
if(!empty($headers)){
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
}
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
if(!empty($filepointer)){
curl_setopt($ch, CURLOPT_PUT, true);
curl_setopt($ch, CURLOPT_INFILE, $filepointer);
curl_setopt($ch, CURLOPT_INFILESIZE, $upload_size);
}
if(!empty($post)){
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
}
//curl_setopt($ch, CURLOPT_VERBOSE, TRUE);
// Turn off the server and peer verification (TrustManager Concept).
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
if(!empty($download_file)){
curl_setopt($ch, CURLOPT_FILE, $download_file);
}
// Get response from the server.
$resp = curl_exec($ch);
echo '<br />Resp: ';
r_print($resp);
echo '<br />Curl Error:';
$curl_error = curl_error($ch);
echo $curl_error;
$errno = curl_errno($ch);
r_print($errno);
$error_message = curl_strerror($errno);
r_print($error_message);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
echo "HTTP_CODE: ".$http_code;
$result = json_decode($resp, true);
r_print($result);
if(!empty($result['error']) && empty($ignore_errors)){
if($result['error']['.tag'] == 'invalid_access_token'){
$error[$result['error']['.tag']] = $l['invalid_access_token'];
}elseif($result['error']['.tag'] == 'incorrect_offset'){
$error[$result['error']['.tag']] = 'Incorrect Offset';
}elseif($result['error'][$result['error']['.tag']]['.tag'] == 'insufficient_space'){
$error[$result['error'][$result['error']['.tag']]['.tag']] = $l['insufficient_space'];
}elseif(!empty($result['error'][$result['error']['.tag']]['.tag'])){
$error[] = $result['error'][$result['error']['.tag']]['.tag'];
}else{
$error[$result['error']['.tag']] = $result['error']['.tag'];
}
return false;
}
return $result;
}
function stream_write($data){
global $error;
if(!is_resource($this->wp)){
$this->wp = fopen($this->tpfile, 'w+');
}
//Initially store the data in a memory
fwrite($this->wp, $data);
$this->tmpsize += strlen($data);
$data_size = strlen($data);
// Are we already more than 4 MB ?
if($this->tmpsize >= 4194304){
rewind($this->wp);
//Call upload append function to write the data from PHP Memory stream to Dropbox
$this->upload_append($this->session_id, $this->wp, $this->tmpsize);
// Close the temp file and reset the variables
fclose($this->wp);
$this->wp = NULL;
$this->tmpsize = 0;
}
return $data_size;
}
// Dropbox API to upload
function upload_append($session_id, $filep, $data_size){
global $error;
$args = json_encode(array('cursor' => array('session_id' => $session_id,
'offset' => $this->offset),
'close' => false));
$upload_url = 'https://content.dropboxapi.com/2/files/upload_session/append_v2';
$headers = array('Authorization: Bearer '.$this->access_token,
'Dropbox-API-Arg: '.$args,
'Content-Type: application/octet-stream');
$resp = $this->__curl($upload_url, $headers, $filep, $data_size);
if(is_null($resp)){
$this->offset += $data_size;
return $data_size;
}
return false;
}
>>the steps to reproduce the issue, including relevant code snippet(s) and parameter value(s), but don't include any access or refresh token(s)
I guess the issue can be reproduced by uploading a file large in chunks of 4MB which could take more than 4hrs to complete
I have previously opened a ticket, in which you can find the error I'm receiving, below is the ticket id for the same:
Ticket #17124496
Awaiting your response.
