New submission from Sean Wang:
I transfered a file from remote Debian host to my local Windows 10 host using SecureFX.
I found that the file's last modifed date was 1900/1/1,0:00:00 on Windows.
I tried to serve this file to be downloaded, and it crashed as follows:
Exception happened during processing of request from ('192.168.1.102', 50978)
Traceback (most recent call last):
File "C:\Python27\lib\SocketServer.py", line 295, in _handle_request_noblock
self.process_request(request, client_address)
File "C:\Python27\lib\SocketServer.py", line 321, in process_request
self.finish_request(request, client_address)
File "C:\Python27\lib\SocketServer.py", line 334, in finish_request
self.RequestHandlerClass(request, client_address, self)
File "C:\Python27\lib\SocketServer.py", line 655, in __init__

File "C:\Python27\lib\BaseHTTPServer.py", line 340, in handle

File "C:\Python27\lib\BaseHTTPServer.py", line 328, in handle_one_request
method()
File "C:\Python27\lib\SimpleHTTPServer.py", line 45, in do_GET
f = self.send_head()
File "C:\Python27\lib\SimpleHTTPServer.py", line 103, in send_head
self.send_header("Last-Modified", self.date_time_string(fs.st_mtime))
File "C:\Python27\lib\BaseHTTPServer.py", line 468, in date_time_string
year, month, day, hh, mm, ss, wd, y, z = time.gmtime(timestamp)
ValueError: (22, 'Invalid argument')
I have checked the source code, and found it was because of the last modifed date of the file, I got this in console:
>>> os.fstat(f.fileno())
nt.stat_result(st_mode=33206, st_ino=4785074604093500L, st_dev=0L, st_nlink=1, st_uid=0, st_gid=0, st_size=3406L, st_atime=1446477520L, st_mtime=-2209017600L, st_ctime=1446370767L)
-2209017600L cannot be handled by "time.gmtime()" method and it throwed
