Dear mysql Debian maintainers,<br>
<br>
As the administrator of a few Dell PowerEdge servers running
Debian Wheezy, I made a general upgrade of two machines today. This
triggered an upgrade of our mysql servers which had several
consequences:<br>
<br>
1) the new version (5.5.40) is not fully compatible with version
5.5.38 . The mysql administrator complained that his service would
not work without changing configuration files.<br>
2) the simple fact of restarting a server while it is involved
in databases replications also causes serious harm according to him.<br>
<br>
Would you be kind enough to consider the following suggestions:<br>
<br>
1) when a new version is not fully compatible with the previous
one, maybe the two versions might be in the repository, but the new
one <b>not</b> considered an upgrade of the old one, so that
routine upgrades do not touch it but the administrator must
explicitely install one and remove the other (like for java-6 vs
java-7).<br>
<br>
2) Even for simple upgrades (the ones which do not touch the
user interface), when about to stop the mysql server, display a
warning about the possible consequences and ask if the administrator
really wants to continue.<br>
<br>
Thank you for your attention.<br>
