1 Implementation of planned tasks

In accordance with the plane of the release there were made the following tasks:

• The implementation of the undo/redo editing changes mechanism in the Vision. — As part of the widget's visual editing window the multi-level changes' undo/redo mechanism is implemented for all basic operations: a visual change in the geometry, changing the value of the widget's attribute, add/remove the widget, copy of the widget and editing of the widgets based on the primitive "ElFigure".
• Adaptation of OpenSCADA to work on the ARM hardware platform. — In addition to the primary adaptation, in the last release for the N800 tablet (http://wiki.oscada.org/Works/Tests/ARM ) the buid and adaption of OpenSCADA for the complex (very old) program environment of the LP-5451 controller was made, and also the build for the SMH2Gi controller and for the Nokia smartphones: N900, N950, N9. As part of the build and adaptation to different mobile devices the following tasks were implemented:
  • DAQ.ICP_DAS: The "ICP DAS" API library libi8k.a for the ARM architecture is added, the ability to build the module for ARM is added.
  • SYS, DAQ.OPC_UA: The system functions floatLE(), floatLErev(), doubleLE(), doubleLErev() are added to convert the storage format of a real number on different architectures.
  • SYS: The adaptation is made to build with the GLibC version less than 2.5 (2.3.2).
  • Archive.FSArch:
    • The LE format real number storage in the archive on the ARM architecture is fixed.
    • The algorithm of the quickly count the number of bits uses the function of not aligned reading TSYS::getUnalign32().
    • The encoding field size in the plane archive of messages expanded from 9 to 99 characters.

2 Optimization, stability, sustainability and system performance increasing

During the work on this version, as well as its practical adaptation, it was discovered and corrected in a total of about 170 error. Also the work on cleaning code from the compiler's warnings with the "-Wall" flag was continued.
Lets list the most significant errors correction of which significantly affected the increasing of stability:

• SYS:
  • The unscheduled calls on the schedule, related to desync of the functions values time() and clock_gettime(CLOCK_REALTIME,&sp_tm), are fixed.
  • The checking and waiting for threads to access due to the overlapping with the previous, eponymous one's stop.
  • The waiting for initialization of the disconnectable tasks is disabled in order to prevent freezing in anticipation of rapidly closing tasks.
  • The work of not aligned reading functions getUnalign*() is fixed on the ARM. The Problem is detected on PXA270.
• Archive.FSArch:
  • The reading data from the archive's buffer in accordance with the buffer's size in the algorithm of fast calculation of the bits' number is fixed.
  • The placement of the offset in the cache from the algorithm of fast calculation of the bits' number.
  • The incorrect handling of the end of not aligned blocks of the fast algorithm for calculation of the bits' number is fixed.
  • The exclusive resource to the calcVlOff() function's call is added in order to prevent the incorrect operation with cache.
• Transport, DAQ.AMRDevs, DAQ.DCON, DAQ.ICP_DAS, DAQ.ModBus, DAQ.OPC_UA, Protocol.HTTP: The usage of the TTransportOut::messIO() function at the request of the tail and getting the zero response is fixed.
• DAQ.ModBus, Transport.Serial, UI.WebCfg, UI.WebCfgD, UI.WebUser, UI.WebVision: The incorrect using of the string terminator '\n' for a variety of software platforms UNIX, MAC, DOS/Windows is fixed, by replacing it with "\x0A".
• Transport.*: The using of unsigned type int the return of the read() and write() functions is fixed. The resources for the counters of the i/o requests are added.
• Transport.Sockets: The missing of the initialization of the size of the return value of the getsockopt() function is fixed.
• DAQ.JavaLikeCalc: The crash of the replace() function of the "RegExp" object is fixed.
• DAQ.Siemens: The receiving and recording the values of real types is fixed. The reconnect in the case of error is fixed. The using of the size property of the integer, real and string is fixed. The cleaning of the parameter's links at its disabling is added.
• UI.Vision, UI.WebVision: The access abroad the vector's size during the rendering of the primitives "FormEls" graphics.
• UI.VCAEngine: The possibility of changes' loss in the visualization server is precluded when displayed in the visualizers by preliminary saving the value of clock counter in the "openList" service request.
• UI.WebVision:
  • The opening and replacing the root page is fixed.
  • The handling of nested pages' scale is fixed, taking into account the scale of the root one.

Optimization and performance improvement:

• SYS: The mechanism of the "ResString" object resource is replaced from the RW-locks on mutex, in order to improve performance and reduce memory consumption.
• Archive.FSArch: The processing of the values' archive index table is ​​significantly accelerated through the use of fast algorithm for computing the number of bits in a 32-bit integer.
• UI.WebCfgD: The group request of the page's contents is used to greatly improve the performance on slow and high latency channels.
• UI.Vision: The rendering performance of the fills of the "ElFigure" primitive is improved.
• UI.VCAEngine:
  • The measures to increase the speed of project's session initiation are implemented: the initialization of the basic attributes because of their subsequent inheritance is skipped.
  • The translation of certain messages of the runtime session is removed.
  • The enabling of only the necessary pages at startup of the session is implemented. Other pages of the running session are enabled when accessed. This has greatly increase the speed of session's startup, as well as reduce the dependence of the starting speed on the complexity of the visualization project.
  • Implementation of the archive mode of the "Document" primitive is changed to direct work with the database, which let to expand the depth of the archive up to the 1000000 documents, and without prejudice to the RAM.

3 Improvement and stabilization of the graphics subsystem

The notable work was made within the graphics system, namely in the VCA engine modules UI.VCAEngine, visualizers UI.Vision and UI.WebVision, as well as in the configurators. The changes were provided for stabilization, the optimization of memory consumption and improvement of user's properties.
