ricellis commented on issue #2480: Partitioned _all_docs endpoint with non-partitioned docId answers with not-properly-formatted HTTP response
URL: https://github.com/apache/couchdb/issues/2480#issuecomment-591363118
 
 
   This is reproducible for me (intermittently, but more often than not).
   `curl -X PUT -u 'u:p' 'http://localhost:5984/test2480?partitioned=true'`
   `curl -u 'u:p' -H 'Content-Type: application/json' -d '{"keys":["invalid"]}' -v 'http://localhost:5984/test2480/_partition/a/_all_docs'`
   ```
   *   Trying ::1...
   * TCP_NODELAY set
   * Connected to localhost (::1) port 5984 (#0)
   * Server auth using Basic with user '****'
   > POST /test2480/_partition/a/_all_docs HTTP/1.1
   > Host: localhost:5984
   > Authorization: Basic ****==
   > User-Agent: curl/7.64.1
   > Accept: */*
   > Content-Type: application/json
   > Content-Length: 20
   > 
   * upload completely sent off: 20 out of 20 bytes
   < HTTP/1.1 400 Bad Request
   < Cache-Control: must-revalidate
   < Content-Length: 73
   < Content-Type: application/json
   < Date: Wed, 26 Feb 2020 10:33:41 GMT
   < Server: CouchDB/3.0.0 (Erlang OTP/20)
   < X-Couch-Request-ID: 9c85a12afc
   < X-CouchDB-Body-Time: 0
   < 
   * Excess found in a non pipelined read: excess = 63, size = 73, maxdownload = 73, bytecount = 0
   {"error":"illegal_docid","reason":"Doc id must be of form partition:id"}
   * Connection #0 to host localhost left intact
   * Closing connection 0
   ```
   
    For me the curl excess is 63 bytes and if I capture them with wireshark they are:
   ```
   2c
   {"total_rows":0,"offset":null,"rows":[
   
   ]}
   3
   );
   
   0
   
   
   ```
   
   So it looks like sometimes the view-like "wrapper" gets mangled into the error response.
