What's new in grp2c (up to version 0.32.0)

You can check what's new in the latest distributed version of the grp2c package, or what features are under development. If you would like to use these features you should apply patches to produce development version of the package. (Almost) complete history of the development is available too.

New method show_name_title in TprsProcess class.
New method show_name in TprsProcess class.
New variable parent in TprsProcess class.
New method show_name_title in TprsProcGroup class.
New method ShowTasks in TprsProcGroup class.
New method grouptype_name in TprsProcGroup class.
0.30.2
New method IsGroup in TprsProcess class.
New class TprsProcGroup has been introduced to represent process groups.
New method has been introduced in TParser class: make_ProcGroup.
GRP systax has been changed: ProgramSection rule has been renamed to Process.
GRP systax has been changed: ProgramSection rule has been changed.
GRP systax has been changed: New rule (ProcessGroup) has been introduced process groups.
New field (Rank) in the TprsProcess class.
New port types: multicast, scatter, reduce, gather. GRP systax has been changed to recognize new type of ports.
GRP systax has been changed: Process rule has been extended with the optional ProcessRank rule.
New data types to represent calculation which must be done by the reduce port.
New field Computation in TprsPort class to store type of computation and Name to store name of the port and ProcID to store numrical ID of connected process if it is defined by its ID instead of its name.
Definition of constructor of TprsPort class has been changed.
ProcSgroup rule has been extended with rule of Calculation.
NameMod field and ModifyName have been removed from TParser class.
Definition of PortDefToProcID rule has been changed.
New methods in TprsProcColl class: FoundProcByID, FoundProc.
C or C++ style comments can be used in GRP files. Nested C commants are not allowed.
New method index_of in class TCollection.
Code generator:
0.31.4
Code generator has been changed to support process groups.
0.29.9
Code generator doesn't generate application header file any more. Every definitions and declarations have been placed in application server program's code directly.
older versions
Bug in generated Makefile to compile user defined code has been fixed.
Error detection capability of code generator has been improved.
Code generator produces unblocking send operations by default.
Code generator generates code which supports guarded communication.
Grapnel API:
0.31.4
New functions in grapnel_cl.h: grp_fopen, grp_fclose, grp_fprintf.
grpi_pinfbyname function has been renamed to grp_pinfbyname and moved to ddstuff_srv.h.
New function grp_pinfbytid has been introduced in ddstuff_srv.h.
0.31.3
First parameter of the ReadMapFile function has been removed.
Libraries have been reorganized. Three kind of libraries are produced. One is linked to both server and client. Second library is especially for server process. Third one is for clients. To support this library structure some files have peen split:
`ddstuff.c' has been split to `ddstuff.c', `ddstuff_srv.c' and `ddstuff_cl.c', as well as `ddstuff.h' has been split to `ddstuff.h', ddstuff_srv.h' and `ddstuff_cl.h'.
`grapnel.h' has been split to `grapnel.h', `grapnel_srv.h' and `grapnel_cl.h'.
And finaly the grapnel API:
`grapnel.c' has been split to `grapnel.c', `grapnel_srv.c' and `grapnel_cl.h'.
DDstuffVersion function has been removed.
New option (-T) recognized by Init function.
0.31.2
Definition of grp_create_proc function has been changed.
New option (-p) recognized by Init function. See how to pass parameters to processes.
0.29.9
Type definition of TProcessInfo has been changed.
Some of Grapnel API functions have been chaged: ReadMapFile, grp_create_proc, grp_create_channel, grp_pre_send, grp_post_send, grp_pre_recv, grp_post_recv
0.29.8
Type definition of struct channel has been removed and TChanDefP has been renamed to Tchannel.
Some of Grapnel API functions have been chaged: grp_create_channel, grp_init_channel, grp_pre_mrecv
grp_nrecv, grp_mcast_array, grp_mrecv, grp_mrecv_array functions have been removed.
