Build Identifier: latest

Various bugs in merovingian:

  1. Not all advertised hashes are supported (SHA256)
  2. java Control doesn't understand new connection methods
  3. errors aren't returned properly according to the protocol
  4. response should not expect trailing new-line.
    The issue numnber 4 is a show-stopper for the release.

Reproducible: Always

"Version: unspecified"

Since you're talking about release show stoppers, know the version you're using would be very useful for us.

Thanks!

Changeset 468d83f26d17 made by Fabian Groffen fabian@cwi.nl in the MonetDB repo, refers to this bug.

For complete details, see http//devmonetdborg/hg/MonetDB?cmd=changeset;node=468d83f26d17

Changeset description:

monetdb TCP control: properly use block-based protocol

Instead of a hacked up blockwise login sequence followed by a
non-blockwise communication sequence, do complete communication
blockwise for TCP connections, and without for UNIX socket connections.

This allows other clients (like merocontrol Java library) not to have to
hack to the max, but use existing connection code for the blockwise
protocol to communicate to monetdbd.

This commit is part of a fix for bug #2979.

Closing this bug, we should file new bugs for the issues we're sometimes seeing with the merocontrol java library, ok?
