From 22c551bb103072826c0299265670d1483c753dde Mon Sep 17 00:00:00 2001 From: Paul Joseph Davis Date: Wed, 16 Dec 2009 00:05:35 +0000 Subject: Provide Content-MD5 header support for attachments. Fixes COUCHDB-558. Thanks to Filipe Manana we now have checks for attachment transfer integrity using the Content-MD5 header (or trailer). Use of this integrity check is triggered by specifying a Content-MD5 header in your request with a value that is a base64 encoded md5. For requests that are using a chunked Transfer-Encoding it is also possible to use a trailer so that the Content-MD5 doesn't need to be known before transfer. This works by specifying a header "Trailer: Content-MD5" and then in the final chunk (the one with a size of zero) you can specify a Content-MD5 with exactly the same format as in the request headers. See the ETap test 130-attachments-md5.t for explicit examples of the request messages. git-svn-id: https://svn.apache.org/repos/asf/couchdb/trunk@891077 13f79535-47bb-0310-9956-ffa450edef68 --- src/couchdb/couch_httpd.erl | 3 +++ 1 file changed, 3 insertions(+) (limited to 'src/couchdb/couch_httpd.erl') diff --git a/src/couchdb/couch_httpd.erl b/src/couchdb/couch_httpd.erl index d0b2e6c2..a61b29fb 100644 --- a/src/couchdb/couch_httpd.erl +++ b/src/couchdb/couch_httpd.erl @@ -541,6 +541,9 @@ error_info({bad_request, Reason}) -> {400, <<"bad_request">>, Reason}; error_info({query_parse_error, Reason}) -> {400, <<"query_parse_error">>, Reason}; +% Prior art for md5 mismatch resulting in a 400 is from AWS S3 +error_info(md5_mismatch) -> + {400, <<"content_md5_mismatch">>, <<"Possible message corruption.">>}; error_info(not_found) -> {404, <<"not_found">>, <<"missing">>}; error_info({not_found, Reason}) -> -- cgit v1.2.3
