Added changes made after 8.2 branch was * created. These mostly have to do with context switching. * * Revision 1.36 1995/10/25 22:48:22 rich * Fixed problems with context switching. Now the context is a separate * data structure accessed from the module data structure, using the * currentContext field. GET_C_GLOBAL is used instead of GET_M_GLOBAL for * the context dependent fields. * * Revision 1.35 1995/10/07 19:07:18 rich * Pre-alpha release of x_ipc-8.2. * Added PROJECT_DIR.

Moved all system includes * into libc.h * Got direct queries to work. * Fixed problem in allocating/initializing generic mats. * The direct flag (-c) now mostly works. Connect message has been extended to * indicate when direct connections are the default. * Problem with failures on sunOS machines. * Fixed problem where x_ipcError would not print out its message if logging had * not been initialized. * Fixed another memory problem in modVar.c. * Fixed problems found in by sgi cc compiler. Many type problems. * * Revision 1.27 1995/04/05 19:10:49 rich * Adding Reid's Changes. * Consolidating the matrix code. * * Revision 1.26 1995/04/04 19:42:13 rich * Added sgi support. * Split low level com routines out to be used in devUtils. * Improved some error messages. * Added central switch to default to direct connections. Does not work yet. * Fixed the vectorization code. * * Revision 1.25 1995/03/30 15:43:02 rich * DBMALLOC works. To use "gmake -k -w DBMALLOC=DBMALLOC install" * Added simple list of strings data structure that can be passed via x_ipc * messages. * Use the string list to maintain a global variable of messages with taps. * Tapped messages are not sent via direct connections. * Implemented code to vectorize data to be sent so that it does not have * to be copied. Currently, only flat, packed data structures are * vectored. This can now be easily extended. * Changed Boolean -> BOOLEAN for consistency and to avoid conflicts with x11. * Fixed bug were central would try and free the "***New Module***" and * "*** Unkown Host***" strings when a module crashed on startup. * Fixed a bug reported by Jay Gowdy where the code to find the size of a * variable lenght array would access already freed data when called from * x_ipcFreeData. * * Revision 1.24 1995/03/28 01:14:32 rich * - Added ability to log data with direct connections. Also fixed some * problems with global variables. It now uses broadcasts for watching variables. * - Added preliminary memory recovery routines to handle out of memory * conditions. It currently purges items from resource queues. Needs to * be tested. * - If the CENTRALHOST environment variable is not set, try the current * host. * - Fixed a problem with central registered messages that caused the parsed * formatters to be lost. * - Added const declarations where needed to the prototypes in x_ipc.h. * - x_ipcGetConnections: Get the fd_set. Needed for direct connections. * - Added x_ipcExecute and x_ipcExecuteWithConstraints. Can "execute" a goal * or command. * - x_ipcPreloadMessage: Preload the definition of a message from the * central server. * * Revision 1.23 1995/03/19 19:39:30 rich * Implemented direct connections using x_ipcDirectResouce call. * Also made the basics.h file a module include. * Changed class in the interval structure to be interval_class to avoid a * conflict with C++. * * Revision 1.22 1995/01/30 16:18:01 rich * Added indications of message byte order and alignment to the message * header in the upper two bytes of the classID. * Now the receiver translates the byte order but must receive data in * "PACKED" alignment. * Made -gstabs come after -g for i386_mach machines so the debugger will work. * * Revision 1.21 1995/01/18 22:40:34 rich * X_IPC 7.9: Speed improvements. * Use unix sockets for communication on the same machine. * Eliminate copying. * Optimize loop for arrays, especially simple, primitive arrays. * Optimize the buffer size. * * Revision 1.20 1994/11/02 21:34:13 rich * Now works for linux machines (i486). * Got afs to work on alpha (and hopefully other vendor OS's) * Added generic Makefile. * Made libc.h and x_ipcMatrix.h module includes. * Reduced the size of libc.h by using more system includes. * * Revision 1.19 1994/05/31 03:24:01 rich * Removed CFLAGS_sun4. * Removed cfree and bzero from mem routines. * Set zero wait on both sides of the pipe. Can connect to host using inet * number. * * Revision 1.18 1994/05/25 04:57:22 rich * Defined macros for registering simple messages and handlers at once. * Added function to ignore logging for all messages associated with a * global variable. * Moved module global variable routines to a new file so they are not * included in the .sa library file. Gets better code sharing and lets you * debug these routines. * Added code to force the module variables to be re-initialized after the * server goes down. * x_ipcClose now will not crash if the server is down and frees some module * memory. * The command line flag "-u" turns off the simple user interface. * Added routines to free hash tables and id tables. * * Revision 1.17 1994/05/17 23:15:53 rich * Added global variables and associated routines. * Added some error checking. The central connection is now set to -1 * rather than zero to prevent x_ipc messages from being send to stdout. * Now compiles on the sgi machines. Still need to have the endian and * alignment figured out automatically. * * Revision 1.16 1994/05/05 00:49:35 rich * Removed duplicate includes. * * Revision 1.15 1994/05/05 00:46:17 rich * Added a gmake makefile GNUmakefile so that the system can be easily * compiled on different machines. * Can now create the targets: tarfile and ftp for creating versions for * export. * * Fixed a number of places were x_ipcExitHnd was not expected to return. * Set the x_ipcSeverGlobal to 0 when the socket is closed. * * Revision 1.14 1994/04/28 16:16:09 reids * Changes in X_IPC Version 7.6: * 1) New functions: x_ipcIgnoreLogging and x_ipcResumeLogging * 2) Code for MacIntosh (MPW) version of X_IPC * * Revision 1.13 1994/04/26 16:23:30 rich * Now you can register an exit handler before anything else and it will * get called if connecting to central fails. * Also added code to handle pipe breaks during writes. * * Revision 1.12 1994/04/16 19:42:17 rich * First release of X_IPC for the DEC alpha. * Changes were needed because longs are 64 bits. * Fixed alignment assumption in the data message format. * Fixed the way offsets are calculated for variable length arrays. This * was a problem even without 64 bit longs and pointers. * * Added the commit date to the version information printed out with the -v * option. * * Now uses standard defines for byte order * (BYTE_ORDER = BIG_ENDIAN, LITTLE_ENDIAN or PDP_ENDIAN) * * Defined alignment types: ALIGN_INT ALINE_LONGEST and ALIGN_WORD. * * *** WARNING *** * sending longs between alphas and non-alpha machines will probably not work. * *** WARNING *** * * Revision 1.11 1993/12/14 17:33:44 rich * Changed getMGlobal to GET_M_GLOBAL and changed getSGlobal to * GET_S_GLOBAL to conform to Chris' software standards. * * Patched problem with connecting between machines with different byte * orders. The real fix requires changing the way formats are stored. * Searching for structural similar formats does not guarantee that you * find the right format. * * Revision 1.10 1993/11/21 20:17:56 rich * Added shared library for sun4c_411 sunos machines. * Added install to the makefile. * Fixed problems with global variables. * * Revision 1.9 1993/10/21 16:13:53 rich * Fixed compiler warnings. * * Revision 1.8 1993/10/20 19:00:35 rich * Fixed bug with self registed messages in the lisp version. * Added new routine : x_ipcGetServerGlobal to get the server socket. * Fixed some bad global references for the lisp version. * Updated some prototypes. * * Revision 1.7 1993/08/30 23:14:00 fedor * Added SUN4 as well as sun4 compile flag. * Corrected Top level failure message name display with a define in dispatch.c * * Revision 1.6 1993/08/30 21:53:32 fedor * V7+V6+VXWORKS Everything compiles but there are initialization problems. * * Revision 1.5 1993/08/27 08:38:39 fedor * Pass 2 aat a V7+V6+VxWorks merge. Many many problems with pointless casting. * * Revision 1.4 1993/08/27 07:14:59 fedor * First Pass at V7 and V6+VXWORKS merge * * Revision 1.3 1993/08/23 16:01:28 rich * Changed the global include files so that they don't double include * system files. This was causing problems on the mach machines. * * Revision 1.2 1993/08/20 00:26:06 fedor * commiting others changes * * Revision 1.1.1.1 1993/05/20 05:45:43 rich * Importing x_ipc version 8 * * Revision 8.1 1993/05/20 00:29:59 rich * RTG - initial checkin of Chris Fedor's version 8 of x_ipc * * Revision 1.2 1993/05/19 17:23:55 fedor * Added Logging. * * $Revision: 1.1.1.1 $ * $Date: 2004/10/15 14:33:15 $ * $Author: tomkol $ * *****************************************************************************/ #ifndef INCglobalM #define INCglobalM #include "libc.h" #include "tca.h" #include "basics.h" #include "tcerror.h" #include "strList.h" #ifdef DOS_FILE_NAMES #include "tcaInter.h" #ifndef NMP_IPC #include "tcaMatri.h" #endif #include "formatte.h" #else #include "tcaInternal.h" #ifndef NMP_IPC #include "tcaMatrix.h" #endif #include "formatters.h" #endif /* DOS_FILE_NAMES */ #include "datamsg.h" #include "idtable.h" #include "hash.h" #include "list.h" #include "key.h" #ifdef DOS_FILE_NAMES #include "behavior.h" #else #include "behaviors.h" #endif #include "resMod.h" #ifndef NMP_IPC #include "monMod.h" #endif /* NMP_IPC */ #include "tcaMem.h" #include "dispatch.h" #include "com.h" #ifdef DOS_FILE_NAMES #include "comModul.h" #else #include "comModule.h" #endif /* DOS_FILE_NAMES */ #include "tcaRef.h" #include "recvMsg.h" #include "sendMsg.h" #include "reg.h" #ifdef DOS_FILE_NAMES #include "centralM.h" #else #include "centralMsg.h" #endif /* DOS_FILE_NAMES */ #include "logging.h" #ifdef DOS_FILE_NAMES #include "modLoggi.h" #else #include "modLogging.h" #endif /* DOS_FILE_NAMES */ #include "modVar.h" #ifdef NMP_IPC #include "lex.h" #endif #ifdef THREADED #include "multiThread.h" #define LOCK_M_MUTEX lockMutex(&GET_M_GLOBAL(mutex)) #define UNLOCK_M_MUTEX unlockMutex(&GET_M_GLOBAL(mutex)) #define LOCK_C_MUTEX lockMutex(&GET_C_GLOBAL(mutex)) #define UNLOCK_C_MUTEX unlockMutex(&GET_C_GLOBAL(mutex)) #define LOCK_CM_MUTEX { LOCK_M_MUTEX;
