This patch adds enhancements or fixes defects of the eloqcore
program as released with Eloquence B.08.10. This patch will be
integrated in the Eloquence B.08.10 release.
Eloquence B.08.10 must be installed before applying this patch.

Patch PE81-1302180
------------------
Platforms: All
* Fixed a problem when assigning COM variables that could result in
an internal failure with a message as below.
Assertion failed: (((sym) & 0x8000))
file prerun.c, line 1847 in function link_com
Patch PE81-1301231
------------------
Platforms: Windows
* Fixed a problem where printing could fail on Windows 8 and
Windows Server 2012 (#4120).
Patch PE81-1211201
------------------
Platforms: HP-UX, Linux
* Fixed a race condition obtaining a unique taskid. If multiple
eloqcore processes are started simultanously eloqcore could fail
with a message as below.
Taskid already in use
eloqcore: Unable to setup daemon session
Patch PE81-1106210
------------------
Platforms: All
* The DEFSTRSZ and AUTOSTRSZ configuration options were added to
eloq.config and the user/group specific configuration files.
They may be used to configure the default dimension of string
variables.
AUTOSTRSZ specifies the dimension of string variables that are
implicitly allocated upon use (auto variables).
For example, A$="TEST" or A$(1)="HELLO".
DEFSTRSZ specifies the dimension of string variables that were
declared without specifying the dimension.
For example, DIM A$(1:10) or COM A$.
DEFSTRSZ defaults to a 18 characters. AUTOSTRSZ defaults to the
DEFSTRSZ value.
For example, the configuration below specifies that undeclared
string variables are allocated with a size of 100 characters:
option AUTOSTRSZ 100
Consequently, the following statement works without causing a
string overflow error:
A$=RPT$("X",100)
PLEASE NOTE:
- Changing the default string variable dimension may have an impact
on existing applications. More memory is used for string variables.
Also, the application may fail if it relies on the default string
variable dimension.
Specifically, variables used in a PACK USING statement will
change the layout of the resulting packed buffer. It is strongly
recommended to explicitly declare all variables used in a PACK
USING statement.
- It is recommended to not specify the DEFSTRSZ option. This will
limit any potential impact to auto variables which are expected
to be less critical. It recommended to only change AUTOSTRSZ
after careful consideration.
Patch PE81-1104280
------------------
Platforms: All
Bug fixes:
* Fixed a bug when passing a structure by value to a function or
subroutine. This could result in an eloqcore crash or abort.
* Fixed a problem with 64 bit builds when passing structures
in the common block.
* Fixed a problem in detecting a user defined type was referenced
in a type definition. This would result in a failed consistency
test.
* Fixed a problem when interactively assigning a structure
(#1136, #3850). This resulted in a failed consistency test.
* Fixed a problem when accessing member variables after the
program was stopped. In this case the type definitions were
Discarded though the program variables were still accessible.
this resulted in a failed consistency test.
Enhancements:
* Add support for DBINFO mode 114.
* Add keepalive support for JDLG connections. This requires
JDLG version 1.5.7-110429-1914 or newer.
DLG SET ".keepalive",Seconds
If Seconds is nonzero, JDLG sends keepalive messages in the
specified interval during a DLG DO or POPUP BOX instruction.
This allows eloqcore to detect whether a JDLG connection is
still active. The latter case is assumed if eloqcore does not
receive any message from JDLG for five times the specified
interval during a DLG DO or POPUP BOX instruction. If an
interrupted JDLG connection is detected, the connection is
closed and ERROR 684 is returned to the program.
This function may also be useful to solve idle timeout problems
caused by network router/firewall configuration. A network
router might be configured to close a connection if it has been
inactive for some time. To prevent this from affecting JDLG
connections, a JDLG keepalive interval could be set.
For example, assumed the router idle timeout is 30 minutes,
DLG SET ".keepalive",900 would cause JDLG to send a keepalive
message every 15 minutes so that the router idle timeout
would not expire.
Instead of using DLG SET ".keepalive", the keepalive interval
may be configured using the JDLG eloquence.config.keepalive
property, for example: eloquence.config.keepalive=900
* Add idle timeout support for DLG network connections.
This may be used with JDLG or Windows DLG (DLGSRV32).
DLG SET ".timeout",Seconds
If Seconds is nonzero and the specified timeout has expired
during a DLG DO or POPUP BOX instruction, the DLG connection
is terminated and ERROR 684 is returned to the program.
This may be used to automatically terminate DLG sessions that
have been idle for a long time. For example, a
DLG SET ".timeout",28800 would terminate any DLG session that
has been idle for more than 8 hours.
Patch PE81-1102220
------------------
Platforms: All
* Fixed a wrong consistency check in the LEN function that caused
an internal failure with strings longer than 32767 characters.
An error message as below was output:
Assertion failed: res->v.s.len >= 0 && res->v.s.len < 32768
file string.c, line 94
Patch PE81-1102070
------------------
Platforms: All
* Fixed an internal buffer overflow in the MD5$ function which
could cause the eloqcore program to abort unexpectedly (#3885).
