ELOQUENCE B.07.00 - patch 0411190

----------------------------------------------------------------------

This patch fixes a defect of the Eloquence database client library
as released with Eloquence B.07.00. This patch will be integrated
in the Eloquence B.07.00 release.

Eloquence B.07.00 must be installed before applying this patch.

Severity:
 PE70-0411190: CRITICAL (application aborts)

Patch PE70-0411190
------------------

Platforms: HP-UX, Linux

* This patch fixes a race condition with shared memory communication
  that could result in applications to abort unexpectedly with status
  -700:-6. An error message like below is written to the console (#2528).

    semop(DOWN): Invalid argument (errno 22)
    Failure during wait on server response

    semop(DOWN): Identifier removed (errno 36)
    Failure during wait on server response

    Unexpected schedule flag value

  When using a common shared memory segment for communication with the 
  server (EnableIPC=2 is configured on the server) the client library
  marks the shared memory region as invalid when closing the server 
  connection. However, this was done in the wrong order.
  This could result in a problem if the shared memory segment was 
  immediately reused by a new connection.

* Changed internal library revision to "B.07.00.05"


Patch PE70-0406021
------------------

Platforms: Windows

* This patch fixes is required on Windows when the image3k patch
  PE70-0406020 (or newer) is installed. Otherwise loading of the 
  image3k library fails due to undefined externals.
  The image3k DBMAINT intrinsic requires that additional functions 
  are exported from the Eloquence client library.


Patch PE70-0406010
------------------

Platforms: All

* This patch fixes a compatibility problem with the image3k DBINFO
  mode 301 (#2300).

  The image3k library internally makes use of the Eloquence DBINFO 
  mode 303 to implement DBINFO mode 301. However the Eloquence 
  DBINFO mode 303 did not return sort item information when a 
  master set was provided as qualifier.
  The Eloquence client library was changed to return the sort item 
  in the related detail set when a master set is passed as qualifier.

* Changed internal library revision to "B.07.00.04"



Patch PE70-0305230
------------------

Platforms: All

* Fixes a regression in idb_logon()

* Changed internal library revision to "B.07.00.03"


Patch PE70-0305210
------------------

Platforms: All

* The EQ_DBUSER and EQ_DBPASSWORD environment variables did
  not work as expected with the TurboIMAGE compatibility (#1970).

  The EQ_DBUSER and EQ_DBPASSWORD environment variables may be
  used to specify the default user and password to access the
  database. However they were only considered when the Eloqunce
  idb_logon() API function was called.
  With the image3k library the idb_logon() API function is only
  called when a user and password is specified and consequently
  the defaults are ignored.

  The Eloquence database client library has been modified to use
  the default user and password, independendly if the idb_logon()
  API function is called.

* The idb_logon() function has been modified to recognize empty
  user and password (zero character string) as no password (#1970).

* Eloquence may call malloc to allocate zero bytes (#1918)
  While this is not a problem it may cause problems with code
  verification tools, such as Electric Fence.

* Changed internal library revision to "B.07.00.02"
