Patch PE81-1210040
------------------
Platforms: All
* Fixed a problem where under rare conditions the HTTP thread
could terminate unexpectedly on a failed network call (#4094).
A message like below would be logged:
X0: [7] getsockname failed. [22] Invalid argument
D0: [7] Unable to obtain local address - dropping connection
As a consequence, the HTTP status did no longer respond.
Also, this could cause new connections to hang because an
unexpected thread id was used.
* Fixed a problem where the database server process could abort
during startup with a message like below (#4110):
Assertion failed: node
server panic: Aborting on internal failure, file nodecore.c, line 1437
A forward-log record was wrongly initialized under some rare
conditions.
* Fixed a problem where a dbutil UPGRADE DATABASE command could
cause the database server process to abort with a message like
below (#4098):
Assertion failed: col->colid > unique
server panic: Aborting on internal failure, file syscat.c, line 4393
This could happen if UPGRADE DATABASE was applied to a database
where the items were reordered alphabetically so that the column
identifiers were no longer incremental.
* Fixed potential performance issue on TurboIMAGE DBFIND modes 1/21
on index items (#4101).
An index search on key arguments containing the * or [ characters
could be inefficient in certain cases due to internal wildcard
masking rules.
* Fixed a potential compatibility problem with dbstore archives
that were created with newer database server versions (#4073).
* Improved the database compatibility checks on DBOPEN (#4073).
* Added diagnostic messages on internal log record hash
inconsistency (#4068).
Patch PE81-1110210
------------------
Platforms: All
* Fixed a problem where under rare conditions the database server
could abort due to a segment violation if multiple dbctl list
invocations were issued at the same time (#4065).
Patch PE81-1109290
------------------
Platforms: All
* The dbctl list session and dbopen commands as well as the HTTP
status session and database lists could in rare cases cause the
database server to abort due to a segment violation (#4063).
This was caused by an internal race condition where a session
was accessed that was just closing a database.
Patch PE81-1109210
------------------
Platforms: All
* The dbctl list db and dbopen commands as well as the HTTP status
database list could in rare cases cause the database server to
abort due to a segment violation (#4062).
This was caused by an internal race condition where a session
was accessed that was just shutting down.
Patch PE81-1109020
------------------
Platforms: All
* Fixed a problem that could result in a database server hang
due to an internal deadlock under rare conditions (#4059).
If a data volume runs out of space while on-line backup mode
is active, a transaction record is written to the log volume
to postpone the data volume extension until on-line backup
mode is stopped.
Under rare conditions, writing this transaction record could
overlap with a concurrent checkpoint operation in a way that
an internal deadlock could occur.
Patch PE81-1102250
------------------
Platforms: All
* Fixed a corner case incompatibility with TurboIMAGE (#4024).
In TurboIMAGE a failed DBFIND call does not change the
current chain. This behavior change does not apply to
programs written in the Eloquence language.
This change is only effective if this patch and the related
client library patch PE81-1102251 (or newer) are installed.
Patch PE81-1012200
------------------
Platforms: All
* Fixed a problem where in a rare corner case the database server
process could abort with a message like below (#3781):
Assertion failed: !node->ref_count
server panic: Aborting on internal failure, file nodecore.c, line 388
This was caused by an internal race condition between client
session termination and a concurrent dbpurge operation on one
of the involved databases.
Patch PE81-1011110
------------------
Platforms: All
* Fixed a problem that could result in a server panic when
deleting a record. The following message is written to the
server message log:
Assertion failed: set_ctx->idx_mode == IS_INVAL
This can happen under the following conditions:
1. The database is accessed from the Eloquence language
2. The database client cache is enabled
3. Some records were read (eg. sequential) but additional
records are in cache
4. A DBFIND on an index item in the same data set is called
5. A DBELETE is called to delete the record
In this case the current record differs between the client
and server side and nees to be re-established. However, a
DBDELETE did not expect a previous index lookup in this case.
