RHBA-2014:0727 - Bug Fix Advisory

Topic

Updated evolution-data-server packages that fix several bugs and add one
enhancement are now available for Red Hat Enterprise Linux 7.

Description

The evolution-data-server packages provide a unified back-end for applications
which interact with contacts, tasks and calendar information. Evolution Data
Server was originally developed as a back-end for the Evolution information
management application, but is now used by various other applications.

This update fixes the following bugs:

• Because of erroneous code segments in Evolution Data Server, a failed IMAP

message download generated a redundant error message and did not trigger another
download of the IMAP message. This update fixes the erroneous code. Now, when an
IMAP message fails to download, the Evolution client attempts to download the
message again as intended. (BZ#1097250)

• Prior to this update, if the Evolution client disconnected unexpectedly from

the IMAP server, a bug caused the Evolution client to display an error instead
of attempting to reconnect automatically. This update implements a fix for the
mentioned bug and Evolution now correctly attempts to reconnect to the IMAP
server after a disconnect. (BZ#1097251)

• Due to errors in its underlying code, memory leaks could occur in Evolution

Data Server. This update amends these errors and the memory leaks now no longer
occur. (BZ#1097253)

• Prior to this update, the Evolution client unintentionally removed the cache

of the IMAP subfolder when the "scanning for changed messages" process failed
(for instance when the user cancelled this process). As a consequence, Evolution
in some cases had to download summary information for all the messages in the
mail folder, including the ones with information previously already downloaded,
which was consuming excessive time and resources. With this update, a fix has
been implemented for Evolution to handle scan interruptions properly. As a
result, Evolution no longer removes the IMAP subfolder cache and thus does not
have to download redundant message information. (BZ#1097252)

• Previously, a bug prevented Evolution Data Server from correctly processing

shared mail folders on a Cyrus IMAP server. As a consequence, when it accessed a
share message folder on a Cyrus IMAP server, Evolution could not display the
messages the folder contained. This bug has been fixed and accessing shared mail
folders on a Cyrus IMAP server with Evolution now functions as intended.
(BZ#1100240)

In addition, this update adds the following enhancement:

• This update introduces the support for multiple connections during IMAP

operations into the IMAPX library. Now, IMAPX is significantly more responsive
during demanding IMAP operations, such as folder updates. (BZ#1097249)

Users of evolution-data-server are advised to upgrade to these updated packages,
which fix these bugs and add this enhancement.
