Is there a 2 GB file size limit in Subversion - Apache? 413 Request Entity Too Large -- Solution

[Curley, John]

Hi all,

FYI.

There seems to be a 2 GB file size limit, if you use the default command to commit. We encountered this problem and eventually found the solution.

This is not a Subversion limit, nor is it an Apache limit.

The default module for accessing the repository is ra_neon. This module (!) has the 2 GB limit. If you specify using ra_serf (serf) instead, that works.

This is the command line option (from the client): --config-option servers:global:http-library=serf

I don't know how to do this in a GUI situation. It took me a LONG time to find this on the web.

Happy new year, now that I finally found the fix!
John

I believe this is only a limit on windows platforms.  The ra_neon
layer appears to be sending a negative size value in the http header.
Possibly a missing cast in the code.  I never was able to debug
it further.  As you found, using ra_serf (or using ra_neon on most
unix platforms) should work fine.  I've seen 20GB+ commits work.

(It appears the actual limit is the size of the compressed delta of
an individual file needs to be less than 2GB.)

You can configure the servers file to specify the use of ra_neon:
(This would actually default all clients to use serf)

http-library=serf
