[Solved] Unable to upload file larger than 2gb
Added by hdn2014 over 10 years ago
Hi,
I am running lighttpd 1.4.35 (ssl) under RHEL6.5 using Python 2.6.6. In "lighttpd.conf", I tried to change "server.max-request-size" to one of these 3 possible values (btw 3145728=3gb):
#server.max-request-size = 0 server.max-request-size = 0 server.max-request-size = 3145728
To test, I am using this "index.html":
<html><body> <form enctype="multipart/form-data" action="cgi-bin/save_file.py" method="post"> <p>File: <input type="file" name="file"></p> <p><input type="submit" value="Upload"></p> </form> </body></html>
and upload script "save_file.py":
#!/usr/bin/env python import cgi, os import cgitb cgitb.enable() form = cgi.FieldStorage() fileitem = form['file'] if fileitem.filename: fn = os.path.basename(fileitem.filename) open('/var/www/lighttpd/files/' + fn, 'wb').write(fileitem.file.read()) message = 'The file "' + fn + '" was uploaded successfully' else: message = 'No file was uploaded' print """\ Content-Type: text/html\n <html><body> <p>%s</p> </body></html>
and added these lines to "lighttpd.conf" to add cgi support:
server.modules += ("mod_cgi") $HTTP["url"] =~ "^/cgi-bin/" { cgi.assign = (".py" => "/usr/bin/python") }
There is no problem uploading any file smaller than 2GB but when I tried to upload a 2GB+ file, the browser (Firefox, IE) immediately aborted with this error:
The connection was reset The connection to the server was reset while the page was loading.
Am I missing anything besides setting the "server.max-request-size" parameter? Btw, I tried to do this in Ubuntu 14.04 (with commented out "#server.max-request-size") and have no problem uploading the same file (2.5gb). Lighttpd log files did not show any error.
Any help would be greatly appreciated. I struggled for many hours on this. Google'ing but didn't see anyone with similar issue and/or solution.
Thanks!

There is an SSIZE_MAX hard limit, which on 32-bit is 2GB (minus 1).
Also I hope you know what you're doing, because requiring large upload sizes like this sounds crazy.

Fixed in lighttpd many years ago in lighttpd 1.4.44, using off_t
for Content-Length.
