This list is a crude list of the Changes made to DRAMA. It was started
on 7-Aug-1995. It is not considered perfect and in particular, may not
have full details of Imp and Sds changes. The assumed author of the changes
is TJF.
argument list into an SDS structure. Can be used by user
code as well (current has a C++ interface, I might change that).
git/dtcl sub-systems:Revamp shared library build - had found that libdrama.so was
actually empty under linux.
2006
After 16-Mar-2009.
23-Nov-2006
dtcl sub-system: Catch fatal X11 IO errors and tidy up DRAMA
correctly as we go down. Tried to keep things going when it was not the main
display, but this does not work reliably due, in part, to a Tcl/Tk bug.
20-Nov-2006
config sub-system:Add rxvt terminals to the listed supported by the ccdv program.
07-Nov-2006
Support VxWorks defining INT64 based on _WRS_VXWORKS_5_X

and ensure ValidateConsts() is invoked by testlink.
15-Oct-2006
dtcl sub-system:Fix bug in dtk, should be evaulating startup code using
Tcl_GlobalEval() instead of Tcl_Eval() to ensure it is always
executed in the global namespace. This resolves a bug triggered if DTCL
was loaded dynamically in a procedure.
18-Sep-2006
imp sub-system:Add support for environment variables IMP_FIRST_BUFFER_SIZE and
IMP_INT_BUFFER_SIZE. If defined, these values (in bytes) override the new defaults in imp.h.

dits sub-system:Add DITS_ARG_READFREE and DITS_ARG_FREE
flags to DitsPutArgument().
dits sub-system:ditscmd (unix) now supports -a [file] argument, which allows
us to specify a file containing the arugment structure, making
it easier to set up test scripts etc.
dits sub-system:ditscmd now sizes it global buffer appropiately for the reply
buffer and the message buffer appropiately for the argument.
dtcl sub-system:Add new -argreadfree and -argfreeid options
to the message sending commands.
dtcl sub-system:Add new READFREE and FREEID argument values
to DitsPutArgument command.

size in dtk.c, dtcl.c.
17-Aug-2006
config sub-system:Add "-lresolv" to solaris links
16-Aug-2006
sds sub-system:Add new methods DataAddressRW() and DataAddressRO() to
SdsArrayAccessHelper(). sdslist command now handled bad arguments correctly.
21-Jul-2006
sds sub-system:Add and use new constant SDS_C_MAXARRAYDIMS for the maximumn array dimension. Add new ArgCheckItem function and CheckItem C++ method. Add SDS_C_MAXCODE constant. Add constant ARG_NEWCPP_OVERLOADS which might help in working out if we are using the new C++ overloads.
17-Jul-2006
config sub-system:Rename macro DramaSystem to IsDramaSystem since using DramaSystem stops us building within a Directory named DramaSystem.
14-Jul-2006
drama sub-system:dramastart now passes arguments to program to be run.
dramastart documentation and some of the output improved.
dits sub-system:DitsKillByName() now kills all actions of the
specified name when the action is spawable.
djava sub-system:Ensure the testlink application uses the current
version of the sharable library (set LD_LIBRARY_PATH
and DYLD_LIBRARY_PATH correctly)

rather then trying to pass a pointer in an Sds structure with DitsSignal()
in the DcppTask class.
10-Mar-2006
Sdp and Arg C++ intefaces modified to make code portable to 64 bit machines.
Various improvements to GitLogger.

Add a Log function to the Git logger which allows a time tag to be specified
arther then just using the system time. Add GetLogger() static method to
GitLogger class.

Added DitsPathToName() and DitsGetActNameFromIndex().
Handle the case where transmitter is trying to send messages but
thinks the current machine is the IP address 127.0.0.1. This case
causes a connection to hang and indicates a mis-configured /etc/hosts file. IMP
now reports the problem sensibly.
28-Nov-2005
Config Sub-system, AnsiC() etc. macros now have -Wno-long-long so that we
don't get warnings about using long long types - allowing 64 bit support
when available.

pointer when it is not created. DcppDispatch must not get transaction
data when the transaction id is null.
17-Jun-2005
Bad status form an action end routine causes strange errors - tidy up.
19-Mar-2005
Fix bug in ImpZProcId() under VxWorks.

09-May-2000
Added DJAVA (DRAMA Java interface) to release (Currenlty supported by
solaris JDK 2.0 only). There is a link with all the details on the
main DRAMA web page.
Added dversion command. This allows you to select a DRAMA
version without having to redo the DRAMASTART command. Unix only
at this stage.
04-May-2000
Possible Incompatiblity The UFACE routine put by
DitsUfaceCtxEnable() is now cleared after a return from
DitsMsgReceive(). This ensures the UFACE routine is consistent,
which was not the case in the past. If you call DitsMsgReceive and
may send messages at UFACE context, then you must make sure you call
DitsUfaceCtxEnable() each time before sending the message. As part
of this, DRAMA is no more consistent at making sure the correct uface
routine is available when invoking uface routine.
23-Feb-2000
Output a better message is the IMP transmitter task does not have sufficent
global buffer space for the reply direction buffers
Ensure that if we have received a connection from another task, we can
get a path to that task. This was causing problems if we had not
received any messages from the other task after it had got its path
to us.
22-Feb-2000
Add a version of DcppMonitor::Forward which provides a
StartedHandler argument. The DcppMontior class
functions which take variable argument lists provide an alternative
format for the list.
01-Dec-1999
Add DitsMsgWait() which allows a task to block waiting for
a message without reading it.
19-Nov-1999
Add DcppShared class to the C++ interface. Add a form of
DcppHandler:SetTimeout() which allows the specification of
a timeout handler routine.
17-Nov-1999
Bulk data kick messages now support the message completion comming back
before the bulk data done message. Added routine
DitsGetEntComplete() which indicates which of the two actually
indicate bulk data completion. Supported by DcppTask C++ Class.
Add support for SdsExportDefined, SdsIsExternal,
SdsGetExternInfo and SdsSizeDefined to the SDS C++
class.
Add DcppSpawnKickArg and DcppSpawnKickArgUpdate - C++
interfaces to the equivalent DITS routines.
Add new versions of Obey method to DcppTask C++ class which
return the transaction id already wrapped up in an SDS class.
Improve layout of complex methods in DRAMA C++ document.
The DcppHandler class increment operators, used to increment the
number of message threads being handled by the class, have been
replaced by the NewThread() method. The operators still exist
but will be removed at some stage.
15-Oct-1999
Can now build DRAMA for VxWorks using GNU make, but this requires that
for any VxWorks build you set the macro HasGnuMake or
HasSunStyleMake in your drama_local.cf file.
14-Oct-1999
Fixed a SDS id leak when kicking spawnable actions via transaction id.
After a suggestion from Jim Wright, added QUIET macro to allow
quiet compilation to be turned off. Use make QUIET="" to
have make display the full compiler command.
Added support for VxWorks on Power PC (targets vwppc and mv2700). Add
target aliases mv167 for vw68k. Thanks to Jim Wright for this.
Note the requriement (on the web install and build page) that if using
VxWorks 5.3 or higher, you must source the appropiate VxWorks developement
script before attempting to build DRAMA or DRAMA applications. Otherwise
the assembler and other tools may not be correctly found. This is becase
VxWorks does not locate the Gnu tools in the standard way.
02-Aug-1999
DRAMA V 1.3b2.
Fixed a bug in the Monitor stuff introduced on 18-Jun, which would cause
a crash under some conditions. Also removes an errant error message on
task loss which has got back in.
Find a bug in Unix release of IMP which would cause program to crash without
warning or coredump. This was a signal handler race condition.
28-Jun-1999
Add the DulInt series of routines which make it easier to
handle Interrupts..
21-Jun-1999
Aded new routines DitsActIndexByName() and
DitsIsActionActive(). The former allows you to fetch the action
index of any action given it's name (the older DitsGetActIndex()
only worked for the calling action). The other routine is used to determine
if an action is active.
18-Jun-1999
Revamp dmakefile's for embedded systems to allow use with both the
new and old Gnu LD program. With the new Gnu LD, we can use the
--whole-arhive and --no-whole-archive flags flags
to enable building of C++ programs under VxWorks.
Improve Ers messages reported when there is insufficent space for a
message.
Fix a problem where by the code which handled buffer empty notifications
for monitored paramters did not itself handle full buffers, which it should.
Add the DRAMA_VERFILE environment variable. You can use this to
check which version file you are using. If you are not using one it's value
is null. (Unix only at this stage).
Dramatically improve the speed of the dramastart command.
21-May-1999
Fixed a bug which resulting in DitsPutTransData()/DitsGetTransData()
interferring with the code associated with UFACE
transactions (see DitsUfaceCtxEnable() and
DitsGetCode().)
12-May-1999
The DRAMA start up scripts ($DRAMA/drama.sh and $DRAMA/drama.csh) now
automatically source equivalent hidden files in the user's home
directories ($HOME/.drama.sh or $HOME/drama.csh). This allows the
user to add there own DRAMA specific start up commands.
DRAMA 1.2, 03-Mar-1999
Release of DRAMA V1.2 to the world.
18-Jan-1998
Add a check to ensure a reference to a transaction in a message
is to one in the range of memory we have used for transaction ids. This
avoids possible access violations if we get a message we should not
(which appears to happen sometimes, even though it should not).
Dec-1998
Add support for Sending Bulk Data.
21-Dec-1998
Improvements to the error reports output by DRAMA if we attempt to send to
a task which has gone away (new code IMP__TASK_GONE) and if we fail to
create a notification semaphore.
08-Dec-1998
Release of DRAMA 1.2 to AAOEPP.
Release of libdrama.o under VxWorks modified. Now don't release
lib*.o files for other systems and rely on gnu ld specific flag
in building libdrama.o. This allows us to correctly build in
c++ stuff for VxWorks. Add implementation of __exit (used by
gnu c++) and cppinit and cppbye required to run global constructors
and destructors). This has been done in GIT library.
8-Dec-1998
Add JAVA language support to messgen.
24-Nov-1998
Add DitsSpawnKickArgUpdate(). Used to update the transaction id in an
existing Spawn Kick structure.
DcppTask::Obey() takes an extra argument, which is an address into
which the transaction id is written. This allows calls to
DitsSpawnKickArg() by tasks using DcppTask.
11-Nov-1998
ADITS now correctly handles rejection of connections by DRAMA tasks. It
also when setting up to monitor ADAM task existance, tries the task
name with a colon appended as a process name if it can't find a process
of the original ADAM task name. (This is needed as ADAM strips leading
colons). A fix to ImpConnect and relevant changes to ADITS ensures that
multiple ADAM tasks can talk to the same DRAMA tasks.
29-Sep-1998
Incompatible change
DTCL now uses TCL's namespaces. All DRAMA commands are now in the
"drama" namespace by default. You can change this to put them in
the global namespace by defining the imake macro DtclUseGlobalNamespace
in your drama_local.cf configuration file. For alternative ways
of selecting this (per login session and per application), see the dtcl manual.
It is recommented that all new DTCL programs use namespaces. Note that this
only works from Tcl 8.0 onwards.
Impending Incompatiblity
We would like to remove support for TCL versions prior to version 8.0. This
will allow considerable code simplifcation and allow the use of more effect
TCL approaches. Please let us know if this would be a problem (This change
will probably occur when Starlink goes to TCL 8.0)
07-Sep-1998
Add the -forcegcc and -nocompcheck flags to
drama_make. This should mean we don't have modify the standard
configuration files at all now.
DRAMA V1.2 Beta 2
01-Sep-1998
DRAMA V1.2, Beta 2.
Beta for Linux testing.
31-Aug-1998
Remove DitsArgType and replace by SdsIdType to avoid confusion. (Type
is still defined to avoid compatibility problems)
01-Aug-1998
Fix some problems in SDSC - the SDS compiler, which were causing crashes
and errors when compiling arrays of structures.
Fix a problem which may cause a crash when using the action wait routines
under VxWorks.
22-Jun-1998
All access to environment variable/logical names in the higher
levels of DRAMA is now via
the Dits routines DitsGetSymbol(), which in turn uses
ImpZGetSymbol() (which will be made public soon. This allows
us to use the Windows registry to get Enviroment details.
DRAMA V1.2, Beta 1.
07-Jun-1998
Improve error reporting from the VxWorks dramastart command.
08-May-1998
Modify DcppTask routines to support interception of Ers and MsgOut messages.
This should be transparent to existing code.
29-Apr-1998
Ers modified to improve results if a program is in a hard loop reporting
errors. Previously, when the error message buffer filled, each addition
messages was output to stderr. Now Ers will dump all messages currently
in the buffer and then start stacking the new messages. This will help
you see the first messages if you are in a hard loop involving error
reporting (calls to ErsRep).
Dtcl modified such that any error in the command specified with the
Dtcl ErrorHandler command (used to output Ers messages) is reported
to stderr instead of attempting to report it via Ers (this never worked
well).
14-Apr-1998
Much work to port DRAMA to WIN32.
Ensure clean compilation with egcs version of GCC (Gcc 2.8 version). This
was done with a very high level of warnings, resulting in many minor
coding problems being picked up. Unlikly to have any effect on
operatoins as none indicated real errors
The transaction id scheme now has it's own memory manager. This manager
should be far more efficent then malloc/free. It has a
slightly higher memory overhead when a small number of transactions are
used, improving with more outstanding transactions.
Added a new routine, ArgFind(). This is functionally equivelent
to SdsFind() except that if an error occurs, it reports the name
of the item you were trying to find. It is suggested that this routine
replace SdsFind() in all applications using the Ers library
(which includes all DRAMA programs). The Sdp library has been so
modified, resulting in more error report lines if you specify an
incorrect parameter name, either from the C calls to SdpGetx/SdpPutx and
from parameter Get/Set messages.
13-Jan-1998
Add DulErsInit(), DulErsMessage, DulErsPutRequest,
DulErsAnnul() and DulErsRep(). These routines allow
you to control the output of Ers messages by subsidiary tasks.
Add DitsUfaceErsRep(). This allows Ers messages from subsidary
tasks to be reported using ErsRep().
Dec-1997
Fixed problem in dtcl sharable library which prevents -wait options to
DRAMA commands from working. Ensured that variables (MessageBytes etc.)
are not overwritten if the values are already set).
10-Nov-1997
Port to Linux. No significat changes needed although exit hander
code layout improved.
07-Nov-1997
Add new -T option to sdsc command. This causes it to output
TCL code instead of C code. The resulting TCL
requires the new version of Dtcl. This is more a test of the
completeness of the new Dtcl but may be usefull in some cases
06-Nov-1997
Add new options to the sdsc command. -f allows you to genereate
an entire function definition instead of just something to be included
in another file. Specify the name of the function immediately after
-f. The -t option allows you to specify the type of a
variable to declare if none is declared within the include file. This
elminate the common requirement for a special case in the include file
to declare a variable in order to force the output of a structure
definition. The variable type is specified immediately after the -t
option. The -N is used with the -t option and specifies
a name for the structure which is created.
The new dmakefile macro SdsIncludeFunction will run sdsc with it's new
arguments. This can replace SdsIncludeFile.
05-Nov-1997
Add new SDS commands to Dtcl, SdsExtract, SdsDelete, SdsFillArray,
SdsGet, SdsGetExtra, SdsInsertCell, SdsNew, SdsPut,
SdsPutExtra and SdsResize
04-Nov-1997
Added new commands DitsLosePath to Dtcl. Exiting command
DitsSetDebug modified to accept enumerated debugging level
names
POSSIBLE COMPATIBLTLY PROBLEM. DitsLosePath now worked in a cleaner
way. It sends a messages back to the task itself which is treated as
indicating the path has been lost. This ensures all transactions which
may be outstanding on the path are tidied up correctly.
Add new routine DulLoadFacs which will load error facilities defined
in the DRAMA_FACILITIES environment variable, as well as ensuring the standard
DRAMA ones are loaded. This call is recommended for User interface programs
to ensure they can translate all codes they might have to.
The DUL library now hass a version of the messana command, which supperseds the
MESSGEN library version. This version loads all the standard DRAMA library
facility talbes as well as those specified in DRAMA_FACILITIES. It outputs
the actual message as well as the numerial parts of a message.
The UNIX DRAMA signal handler is now more consistent in it operation and
therefore more likely to clean up correclty. It should now output an
appropiate error code when a signal is received.
03-Nov-1997
In order to improve access to the HTML pages, the Arg routines have been
split from the Sds routines and the Dui and Sdp routines from the
Dits routines. This makes access to all routine docuementation easier.
Fix some minor SDS id leaks in the monitor software
Revamp the internal debugging system, accessed by DitsSetDebug().
There are now a well defined set of flags for debugging various parts
of the internals of Dits. In addition, the environment variable DITS_DEBUG
is read at initialisation time and the debugging mask set to it's value
if it is an integer.
Add new routines to assist debugging, DitsDumpPath,
DitsDumpAllPaths, DitsDumpTransId and
DitsDumpAllTransIds.
Add new control messages DUMPPATHS and DUMPTRANSIDS.
31-Oct-1997
Various fixes to ADITS, the ADAM to DRAMA interface. Removes a cause of
Crashes and a cause of going into an infinte loops.
30-Oct-1997
The Dtcl module now checks for the existance of the various buffer size
and logging variables before setting them such that when using
the shareable library version, you can set these values before
loading Dtcl.
29-Sep-1997
Fix compilation problems in messgen.c, xditscmd.c and xdc*.c due to apparent
include file differences on a JACH solaris machine. The problem with
messgen.c was the prototype of getopt, which appears to be available when
we compilete with -Xa instead -Xc. The problem with xditscmd.c and xdc*.c
is that we were picking up a stange definition of NULL (possibly char * instead
of void *) and this was causing compilation errors. Have removed all
uses of NULL from these modules.
10-Sep-1997
DcppMonitor object now have new functions IsInitial(), IsStarting() and
IsActive() which can be used to determine the state of the object. In
addtion, the state is check more often throughout the implementation.
09-Sep-1997
Changes to DTCL to support Tcl version 8.0 had broken support for version
7.4 and before. This has not been fixed and Dtcl has been tested with
Tcl version 7.4
03-Sep-1997
DRAMA V1.1.1 Release
Some IMP Bug fixes and adding of RGO's change to the DTCL SDS Image
widget which improves the scaling of images (currently USHORT types only)
Fixes to IMP are
- Fixed problem in the IMP VxWorks task loading routines which caused names
starting with numbers to be interpreted as numbers. This fixes the problem
of the "imppulse" program crashing if a numeric dot format (e.g 123.456.789.012)
was used to specify the machine to pulse.
-
Problems with fifo protections were probably not a umask() problem
at all, but because cleanup -l (or showimp) was changing the protections
of the fifo files! (And was using 0x744 instead of 0744, hence the really
silly protections we got.) Cleanup now uses stat() to determine ownership,
instead of the lash-up involving file protections it was using
-
Enhancement. Change to ImpRegister so that when a task registers it checks
the user noticeboard for any tasks registered as being on the local machine
but which do not in fact exist. It now cleans up (calls ImpTidyAfter()) for
any such tasks. This will tidy up in particular after tasks that were
not loaded by Master and which have not exited cleanly - although it
doesn't happen until a new IMP task runs; it might be nice to have this
sort of check run periodically, perhaps by Master itself.
02-Sep-1997
A connect to a remote machine which is not responding at all, for example,
a VME crate which had the ethernet cable disconnected, would cause transmitter
to hang until the TCP/IP timeout occured (about 200 sec). Transmitter has
now been modified to allow connections to other machines to continue operating
(the connection to the disconnected machine still hangs, this is determined
by TCP/IP)
01-Sep-1997
DRAMA V1.1 Release
Changes made during a trip by KS and TJF to RGO.
- Added a new message code, DITS__NO_NET_ON_REMOTE. This generally
replaces occurances of IMP__SOCK_FAIL and gives a more appropiate
error.
- The VxWorks version of the DRAMA exit handler now checks for more errors,
such as semaphore failures. In addition, a problem which could see task
switching occuring at the wrong time was corrected.
- Various debugging messages were removed as the situations were shown
to be normal occurances
- Documentation errors in the routine DuiExecuteCmd and Tcl commands
Translate/pget/pset/obey/kick/monitor/control where corrected
- In previous versions, a get path timeout in DuiExecuteCmd could cause
a core dump if the path was not found. This bug has been removed.
- IMP Event logging is now switched off by default. This can be switched
on by setting the environement variable IMP_NET_LOG_EVENTS (to
any value) before starting any tasks
- If a task disconnected while receiving a large message from another
machine, receiver was able to get the disconnect message in the middle
of the series of reads from the socket. Receiver would then detach the
shared memory and later try to read into it again. The error that occurred
caused receiver to then mistakenly closed the socket and as a result, the
location of the remote task was lost. This bug has been fixed.
- IF a task loads and tries to register with the name of a task that
had been registered but crashed, it now notifies all the tasks that were
connected to the original task that the original task has disappered.
11-Aug-1997
DRAMA V1.0 Release
06-Aug-1997
The impprobe command has been modified to improve it's display
when large numbers of tasks and connections/buffers are involved. It now
only run on Tk 4.0 and above.
Incorporated Imp update which fixes various problems. Problem of not
being able to clenup receiver under some condition has been fix. This has
required that programs started by ImpMaster not be allowed to read from
stdin. They will get an error condition if they try. The message corruption
problem has been fixed (was only seen when networking was being really
worked hard). Some problems in flow control have been fixed (as a one in
several hundred thousand events problem, this was not see in practice).
28-Jul-1997
Fix a bug in the request notify code which was causing notifications
to be delivered in the reverse of the desired order. This has been fixed.
Support long parameter names in Set messages by use of additions to
the argument structure and the special parameter name _LONG_.
Added new routines DitsSetParamSetup() and DitsSetParamTidy().
These are used by DitsSetParam to set up these long parameter
name argument structures. Modified ditscmd/xditscmd/dtcl to support
long parameter names in both GET and SET messages.
28-Jul-1997
The DITS__NOTIFYWAIT status has been split into several codes.
The original code will now only be returns when your task is initiating
messages (obey's, kick' etc) in other tasks. The following codes may now
be returned DITS__NOTIFYWAIT_TAP, to indicate a general failure
sending a message to a parent action (should not be returned as it should
be converted to one of the others).
DITS__NOTIFYWAIT_MSG will be returned if MsgOut()
got a notify wait condition.
DITS__NOTIFYWAIT_ERS will be returned if ErsFlush()
got a notify wait condition.
DITS__NOTIFYWAIT_TRIG will be returned if DitsTrigger()
got a notify wait condition.
23-Jul-1997
Add DitsAltInDelete. Revamp DitsAltIn routines to allow more fd's and
handle multiple invocations with the same fd.
29-Jun-1997
Don't output messages about unexpected load message unless debugging.
These are normally refering to things started by something else in the
program.
26-Jun-1997
Add IMP-E-SEM_FAIL to the list of imp errors we don't report during
the shutdown process.
26-Jun-1997
Add support in DcppTask class for initiation of an object which will
contain a path to our own task, without having to explictly handle a GetPath
operation
23-Jun-1997
If the parent task of an action dies, then the action is marked such
that is will never send a message to the parent task again.
Add DitsDumpImp() and dumpana. The former routine allows a DRAMA task
to log all DRAMA messages. The later is a simple program to analyze the
dump.
18-Jun-1997
SdsNew was not returning immediately on bad status. This was causing
a core dump in DRAMA when you attempted to get a non-existent parameter.
16-Jun-1997
Don't output debugging messages when we see disonnection messages from
unknown tasks.
13-Jun-1997
DRAMA V1.0, Beta 2. Sent to RGO for testing.
DRAMA works around a problem which occurs when a task dies (kill -9
style) on a Unix machine without having been the child of IMP_MASTER. When
a new connection is seen from the same task and the task id/machine are
different, DRAMA does a path lost operation on the original path.
11-Jun-1997
Fixes to IMP level to fix leak of Semaphores.
Dits now ensures Sdp parameter system is tidied up.
03-Jun-1997
Release of V1.0 to site.
Various fixes to IMP Level restart and resource leak problems.
22-May-1997
Add the new control message type of "DEBUG". It can be used
to enable DRAMA debugging. Any argument is converted to an integer and
supplied to the routine DitsSetDebug(). If no argument is supplied, call
DitsSetDebug with an argument of 1 (normal debug enable call).
If the debug flag is greater then 1, then dump the imp message details
assocaited with a system message.
14-May-1997
Correctly handle the case where, when task A is setting up a connection
to task B, the connection fails because task A does not have sufficent
space. The message back to task B was not being handled correctly due to
Dits and Imp level problems. (Still have underlying IMP problem)
14-May-1997
C++ A code now compiles with the Solaris V4.0 C++ compiler.
If the network tasks are shutdown, we now correctly tell each task communicating
with them on the same machine about this, previously, messages received
had the wrong task names.
08-May-1997
Fix DulFindFile problem - was crashing when translating evnironment
variables with long translation and was not ignoring directories with did
not exist as Vms Find File does.
08-May-1997
Improve the error message when we have a failure in the call to ImpConnect,
in Dits___ImpLocated.
If we get a SendError whilst setting up the path, was clobbering the
path mode before reporting the message and the message didn't make sense.
Add DitsSetDebug command to dtcl.
06-May-1997
Fix problems in handling of Disconnection messages. This involved improvements
in Dits and fixes to Imp. In particular, Dits disconnect handlers will
now always have a valid task name. The Imp changes ensure we tidy up correctly
after a remove machine has gone done.
Update documentation to include See Also: lists in Dits, Dul
and Dtcl libraries. General documentation update.
18-Apr-1997
Add new Sds utility routine SdsTypeToStr which when given a valid Sds
type code will return an appropiate string.
Add ArgSdsList, a routine which does a similar job to SdsList, but allows
you to specify an output routine. (Also add a new static List function
to the Arg C++ class which calls this).
ArgCvt will now accept a new destination type, ARG_STRING2. This behaves
like ARG_STRING in call cases except where the source is a float/double.
In that case, it uses 6/10 digits or precision instead of the maximum amount
available, as used by ARG_STRING.
ArgToString will now handle Array items.
Add DuiLogEntry function, which does a similar job to DitsPrintReason,
i.e., outputs details of an entry to an action. Unlike DitsPrintReason,
it always uses MsgOut, and will print Sds arguments.
DuiExecute now uses ArgSdsList to list sds structures such that sds
structures are now listed using MsgOut instead of to stderr.
Added -printcmd option to Dtcl's SdsList command to take advantage of
the new ArgSdsList function within Dtcl.
Add SdpCreate, SdpGet, SdpPut, SdpGetSds and DitsGetParId to DTCL. This
allows creation and use of parameter systems.
22-Apr-1997
Add the -varcvtcmd argument to the DTCL's monitor command. This allows
you to do conversions on the fly in conjunction with the -variable option.
18-Apr-1997
DTCL's ErsHandler command now appends flags when calling the handler
routine which indicate the Ers message flags (bell, alaram, highlight).
09-Apr-1997
DitsPathGet/DitsGetPath will now reschedule if the path is available
immediately or we are already waiting for a path. This reduces the complexity
in the use of these calls. Flags to DitsPathGet and DitsAppInit (the later
for DitsGetPath) will enable the old style of operation. Inquiry function
mode of DitsPathGet/DitsGetPath now formalized.
DitsLosePath now does not delete transactions assocaited with GetPath
messages.
Can now get and set parameters using structured parameter names, as
supported by the SdsFindByPath call. Note, name length limitations in DRAMA
messages (20 characters) prevents you doing much which these, although
MGET mesages do not have such restrictions. DTCL pget command supports
this by using MGET messages auotmatically when the name is long.
08-Apr-1997
DTCL, monitor command now supports -variable option. Allows monitor
messages to cause variables to be updated automatically. SdsArrayGet supports
-element option.
Parameter Monitoring. Support only sending current value to task which
added that parameter to a transaction (send SEND_CUR flag is set).
When a transaction's parent is a UFACE transaction in the same task,
invoke routine directly instead of sending a message. This should allow
user interface tasks to monitor there own parameters very efficently.
10-Mar-1997
ADITS (Adam/Dits interface) now handles MGET messages.
19-Feb-1997
Version 1.0 Beta CD rom.
17-Feb-1997
The default DRAMA Imake macro to build a program (DramaProgramTarget)
now references the DUL and GIT libraries, as does the default include file
macros.
Under VxWorks, we now release a libdul.o and libgit.o and use these
to build libdrama.o, which is currently found in $GIT_LIB. This library
should be loaded into VxWorks to make the entire DRAMA system available.
12-Feb-1997
We can now build a Dtcl shared library for dynamic loading into wish/tclsh.
Consider adding the following to your Tcl pkgIndex.tcl file
If DRAMA gets a corrupted messages, it will not retry a number of times
(currently fixed to 10). Future versions will add more control to this.
package ifneeded Dtcl 1.0 {
global env
if {[lsearch -exact [array names env] DTCL_DEV] != -1} {
load $env(DTCL_DEV)/libdtcl.so
} else {
error "DTCL_DEV environment varaibler not defined, have you
started up drama"
}
}
This will enable the commands package require Dtcl
12-Feb-1997
Change DitsAppInit flag DITS_M_FC_AC to DITS_M_NO_FC_AC as default mode
of operation has changed. Notification now works correctly with monitors
and return of action completion messages.
Add SharedLibrary macro support to dmakefile's
07-FEb-1997
Fix DTCl/DTK prompting problems under VMS.
03-Feb-1997
Add DitsPutPathData/DitsGetPathData.
Integrate Imp V1.2
31-Jan-1997
continued configuration revamp. Standard configuration files now are
appropiate for standard machine configuratons. Must use local_config.cf
files to adapt for each AAO machine.
Added logging support to DcppTask.
Add MGet routine to DcppTask.
xditscmd transparently uses the MGET message when you try to get mutiple
parameter values.
The dtcl program now accepts the option -nostdin, which says that it
should not prompt from stdin for commands.
The dtk program now accepts the option -stdin which says that it should
always prompt for commands from stdin (by default, it does this only if
a script is not supplied with the -t option)
Fixed bug in DulFindFile which had caused it to crash under VxWorks
when a file did not exist.
30-Jan-1997
Add DitsArgNoDel function which allows Sds structures supplied by DitsSignal
calls to be left alone by DRAMA
Revamp of configuration stuff particually in relation to compling VxWorks
code on a Solaris machine. VxWorks configuration is now set in the local_config.cf
file.
Support VxWorks mips target using information from Alan Bridger.
Don't build strtoul into sds except on SunOs machines.
29-Jan-1997
Added a new routine, DitsAppParamSys used for putting and inquring about
the parameter system, including the monitor routines.
DitsPutParsys and DitsPutParamMon are now obsolute.
DitsGetParId now returns void * instead of SdsIdType.
We now support a new message type, the MGET message, which can be used
to return the values of multiple parameters.
When build VxWorks, dependices for libdits.o are now include all DRAMA
libraries it is dependent on.
28-Jan-1997
Added new programs sdsdump and sdspoke. dui (Dits user interface routines)
report messages on failures of handlers (could result in more mesages from
Dtcl stuff for example). Bug remove from ErsRep calls during interrupts
(Vxworks)
26-Nov-1996
Beta 0.6 release for JACH.
01-Oct-1996
ADITS now uses ADAM net 4 instead of ADAM net 3. This means you have
to use the form
NODE##drama_task
instead of
NODE!!drama_task
from adam programs. This is as it conflicts with the use of adam net
3 by JCMT.
In addition, you can now use a node name of "LOCAL" or "LOCALHOST"
to refer to a task on the machine on which ADITS is running.
26-Sep-1996
DcppHandler Dcppobject now allows you to wait for multiple threads to
complete.
SDSC support of Sds structure arrays now complete (have not tested geneation
on the fly)
New Sds routines - SdsInsertCell, inserts a cell into a structured array.
SdsFillArray fills a structured array with copies of a specified structure.
SdsInsertCell and SdsCell now allow you to treat multidimensional arrays
as one dimensional.
20-Aug-1996
VMS DRAMA handles lack of ADITS sliently.
27-Aug-1996
Sds memory leaks fixed.
01-Aug-1996
SDSC now supports types INT32/UINT32/INT64/UINT64 directly. (Some work
towards Sds structures, but does not work yet due to Sds problems).
30-Jul-1996
Add DitsActionWait command to Dtcl.
dits_netclose now works quickly (tested undr Unix only)
cleanup command now only clean's up scratch files for the current host.
29-Jul-1996
Fix a number of problems in the DitsActionWait/DulGetPathW/DulLoadW
stuff.
Interfaces to DulLoadW and DulGetPathW changes to incorporate use of
DitsPathGet instead of DitsGetPath.
26-Jul-1996
Many of the DitsPut??Handler routines now return the original values.
Where there was not client_data item, they simply return the value and
no application change is required. Where there was a client_data item,
there are now extra arguments to return both the old routine and client_data
items.
DitsAppInit calling sequence has change and some new flags have been
added.
DitsDisconnectRoutineType has changed to add a flags argument.
New DitsPathGet routine replaces DitsGetPath, adding new arguments and
putting the buffer sizes in a structure. DitsGetPath remains but is implemented
in terms of DitsPathGet.
DitsPutActions argument structure has changed to provide a action cleanup
routine. This is invoked when the task is shutdown or in the case of spawnable
actions, when spawed actions complete.
Add DitsPutCode routine.
Improved error reporting when buffer allocation problems occur but only
when local tasks are involved. Currently, buffer allocation problems involving
remote tasks cause system errors due to bugs in Imp.
DitsGetEntInfo/DitsGetEntName now returns the name of the subsidary
action when the reschedule reason involves such a transaction.
A new DITS_M_REP_MON_LOSS flag to DitsInitiateMessage which tell the
monitor system to report monitors lost due to waiting for buffer empty
notifications.
24-Jul-1996
Reply messages now try much harder to get though, using the RequestNotify
mechanisum. (MsgOut stuff does not, ErsOut does not it is not clear that
it should)
Tidy up VMS link procedures and options files.
You now cannot set a structure Sdp parameter. A new routine SdpSetReadonly
now allows you to make a parameter system readonly. There are not SDP_type
codes to replace the use of SDS_type and ARG_type codes. DitsPutParSys
is now does as part of SdpInit.
23-Jul-1996
A host of new commands added to Dtcl. In addition to DitsScanTask/DitsTaskIsLocal/DitsSetDetails
we added various commands to support adding to actions using Tcl and implemented
in Tcl. Some new C level functions were also added.
22-Jul-1996
Add DitsTaskIsLocal routine to Dits Added DitsTaskIsLocal/DitsScanTask/DitsSetDetails
to Dtcl.
19-Jul-1996
Dits and Dul now use DitsMalloc/DitsFree to malloc and free memory.
By default these are macros defined to malloc/free. You cann recompile
both these with these redefined to user defined fuctions to test for memory
leakage.
We now provide dul_cc/dul_link/dtcl_cc/dtcl_link to help in the building
of programs. (dtcl stuff does not actually include Tcl since these routines
don't know where it is)
Solaris link lines now specify -R to enable finding of sharables at
runtime (configuration files only)
30-May-1996
Version 0.5
27-May-1996
SdsFindByPath added to Dtcl/Dtk.
06-May-1996
Messgen now generates a fac__FACNUM code in include files.
02-May-1996
Added new function SdsFindByPath. Added commands SdsListPath.
Configuration stuff now supported DNOFIX_INCLUDES macro. At AAO this
is set up in ~drama/local/drama_local.cf. Also modified ~drama/local/drama_local.cf
and drama_local.opts to support determination that AAOSSC does has not
has fix includes run and does not support C++. DRAMA core stuff using C++
(git/dul) now output warnings if build without C++ stuff.
29-Apr-1996
If a kick message has no transaction id, use the path to the initiator
of the obey for Informational/Error/Trigger messages.
24-Apr-1996
Provide an SdpPutStruct call, similar to SdsPutSds but allows Structures
to be put into structured parameters.
Imp V1.0 incorporated.
Add new flag DITS_M_NOEXHAND to DitsAppInit/DitsInit which allows the
caller to disable the use of the Dits default exit handler.
07-Dec-1995
Recent changes compile cleanly under solaris and alpha.
06-Dec-1995
Dits document updated.
05-Dec-1995
Allow spawnable actions (using DitsPutActions). Add DitsGetActIndex,
DitsKillByName, DitsKillByIndex, DitsSignalByName and DitsSignalByIndex.
DitsKill and DitsSignal are withdrawn (marcos defined to call KillbyName
and SignalByName).
Add DitsSpawnKickArg
Added DitsSignal and DitsKill to Dtcl. Add -kickarg option to obey command.
04-Dec-1995
Configuration file local config files. Notes as per below config document
updated.
01-Dec-1995
DtclBackgroundError correctly handles being called when no error has
occured by reporting the problem.
30-Nov-1995
Type of DitsAltInType changed and inclusion of system include file sys/types.h
(unix), selectLib.h (VxWorks) removed from DitsSystem (and therefore DitsSys)
as a result.
Version 30Nov, perlimary release of Drama 0.5
10-Nov-1995
Added routines DulMessageW, DulGetPathW and DulLoadW, which make use
of DitsActionWait/DitsUfaceWait to allow simple blocking style messages.
09-Nov-1995
DitsAltIn* stuff now used DitsPutEventWaitRoutine.
08-Nov-1995
Added DitsActionWait and DitsUfaceWait* and DitsPutEventWaitRoutine.
Unix version now makes use of the technique designed by Brian McIlwrath
(RAL) to ensure exit() is invoked when signals occurs, as well as ensuring
you get the standard response when the signal is recevied (core dump if
appropriate, correct error message).
06-Nov-1995
Problem with DitsLoad comments are being lost from man pages fixed.
Add optinal OFFSETS item to ImageStructure definition.
Added DitsScanTasks call.
25-Oct-1995
More revamping Dcpp. New documentation of C++ interface. SdsId used
throughout instead of Arg.
13-Oct-1995
Revamp Dcpp stuff. SdsId C++ class now declared in Sds.h and Arg C++
class is now based on it.
10-Oct-1995
Created release r0.4.2
Ensure Imp fixes reflected in DRAMA copy of Imp code.

New routines ArgGeti64/ArgGetu64/ArgPuti64/ArgPutu64 SdpGeti64/SdpGetu64/SdpPuti64/SdpPutu64
Dtcl - Add new routine DtclErsRep. Fixed reporting of errors when Tcl
scripts are read such that we get full stack dump of error. In addition,
DTCL_COMMAND will also return the stack dump of any error.
Dits - Fixed bug where arguments passed using DitsSignal are not deleted.
07-Aug-1995
Start of changes list
ArgCvt now handles 64bit integers correctly. (Note - side-effect, when
calling SdpCreate, items of type SDS_INT/SDS_UINT must use type INT32/UINT32
while SDS_I65/SDS_UI64 must use types INT64/UINT64)
Dtcl now supports Tk 4.0. A new Tk photo image type supports Sds images.
Dul library provides an addition photo image type which supports Fits images.
