I will try to be clear. ;)
To explain this is my trace log :
Case A
2009-11-27 08:00.00 - Copying file AAAA (1.5GB) from server 1 to server 2 (the
copy will finish at 08:05:00)
2009-11-27 08:01.00 - Trying to download AAAA with curl (0.3GB) from server 2
2009-11-27 08:02.00 - Download complete
Case B
2009-11-27 08:00.00 - Copying file BBBB (3GB) from server 1 to server 2 (the
copy will finish at 08:10:00)
2009-11-27 08:02.00 - Trying to download BBBB with curl (0.5GB) from server 2
2009-11-27 08:04.00 - Download complete
So when i try to download the file, it's not fully copied from server 1 but
curl download it normally.
There is no system lock.
Of course when the file is fully copied on the ftp server, the download it's ok
!
This my code (C#) :
Curl.GlobalInit((Int32)CURLinitFlag.CURL_GLOBAL_ALL);
FileStream fs = new FileStream("myfile.bin");
CURLcode code = CURLcode.CURLE_OK;
Easy easy = new Easy();
Easy.WriteFunction wf = new Easy.WriteFunction(OnWriteData);
easy.SetOpt(CURLoption.CURLOPT_WRITEFUNCTION, wf);
easy.SetOpt(CURLoption.CURLOPT_WRITEDATA, fs);
easy.SetOpt(CURLoption.CURLOPT_UPLOAD, 0);
easy.SetOpt(CURLoption.CURLOPT_URL, "sftp://100.100.100.100:999";);
easy.SetOpt(CURLoption.CURLOPT_USERPWD, "user:pwd");
easy.SetOpt(CURLoption.CURLOPT_TRANSFERTEXT, false);
code = easy.Perform();
easy.Cleanup();
fs.Close();
Curl.GlobalCleanup();
private Int32 OnWriteData(Byte[] buf, Int32 size, Int32 nmemb, Object
extraData)
{
FileStream fs = (FileStream)extraData;
fs.Write(buf, 0, size * nmemb);
fs.Flush();
return (size * nmemb);
}
