[nginx] svn commit: r4939 - trunk/src/os/unix

Author: mdounin

New Revision: 4939
URL: http://trac.nginx.org/nginx/changeset/4939/nginx

Log:
Core: fixed ngx_write_chain_to_file() with IOV_MAX reached.

Catched by dav_chunked.t on Solaris.  In released versions this might
potentially result in corruption of complex protocol responses if they
were written to disk and there were more distinct buffers than IOV_MAX
in a single write.
