Version 1.06.068

================

(Made by Mark Cawston, 13 March 2002)

Fixed FER-56EJNS (Inconsistent dealing with zero length Base64 data.)

UMEM\UM_BUF.CPP TMemBuf::Set(TUint8* aPtr,TUint8* anEnd,TInt aMode) changed to

treat null data as seekable zero-length data.

TMEM\T_MSTRM.CPP extended to cover test case.

Version 1.06.067

================

(Made by Mark Cawston, 20 November 2001)

Fixed BAR-4YRCST (Unnecessary stack usage,) by changing EnsurePathL() in UF_DICT.CPP.

Version 1.06.066

================

(Made by Andrew Thoelke, 16 May 2001)

Performance optimisations for PermanentFileStore.

*	Enhanced write-buffering in RFileBuf to maintain the write buffer when overwriting data already in the buffer.

*	PermanentFileStore now checks for a transactional file system (new API from F32) such as LFFS, reducing

the number of overwrites to the file header when commiting and compacting the store.

*	Improved the use of the TOC caches to maintain them whenever possible, rather than invalidating them.

*	Improved the process of writing a new TOC to involve minimal file writes.

*	Added a new compaction algorithm which is still very effective at recovering free space, but moves significantly

less data when the file is more than half used. On large stores (1000's of streams, 100's of K) it can be over 8x

faster when there is approx. 10% free space (this is ignoring the benefits of the LFFS optimisation)

When combined these changes reduce the number of file write requests significantly, which is the predominant

performance factor on slow media (such as flash memory).

This also fixes GT 6.1 defect THE-4UVH4N, introduced by the addition of TOC-delta's to CPermanentFileStore.

Version 1.06.065

================

(Made by Andrew Thoelke, 2 March 2001)

Added TOC (table of contents) 'delta's to Permanent File Store. When 

committed such a store will not always re-write the entire TOC, instead

it will save only the updates since the last full TOC. This can reduce

the average overhead of the TOC when committing the store by over 95%.

This change is to provide a fix for 6.0 defect EDNAPIN-4T4KZD.

The PFSDUMP tool has been updated to understand the new toc structure

and report the store contents as before.

Data compatibility warning:

The new STORE will read and update existing PFS files, but the resulting

files can no longer be read by previous versions of STORE.

Version 1.05.065

================

(Made by Mark Cawston, 12 February 2001)

Fixed EDNMMIR-4QHDUH (CDictionaryFileStore abuses the filing system on a CommitL).

Previously fixed in 6.0 branch by providing 1k threshold for CDictionaryStore::CommitL()

before it compacts.

Version 1.05.064

================

(Made by William Roberts, 7th August 1999)

Fixed the construction of TStreamMark variables, e.g.

			TStreamMark mark=pos;

becomes		TStreamMark mark(pos);

This is necessary for the new GCC compiler because it correctly spots that

STORE\INC\s32share.h: In method `TInt RFrame16Buf::ExtendL(class TStreamExchange &, TInt, TInt = 3)':

STORE\INC\s32share.h:58: `TStreamMark::TStreamMark(const class TStreamMark &)' is private

STORE\USTRM\Us_frame.cpp:59: within this context

Version 1.05.063

================

(Made by Graham Asher, 6th August 1999)

Fixed a defect caused by a GCC linking problem:

GASR-4AGJQX Word panics on closing when Greek letters are entered.

Release 061 - Graham Asher - 24th January 1999

==============================================

Combines releases 051 and 060, thus joining together the two branches of development.

Intended for ER5u (EPOC Release 5 Unicode).

Version 1.05.051

================

(Made by AjThoelke, 8 December 1998)

EPOC Release 5 candidate component

Binary Compatibility

E32TOOLS 095

E32TOOLP 098

E32 release 156

F32 release 122

ARM narrow release size is 69696 bytes (68.1K), as reported from ROMBUILD.

Testing

-------

Test code changed to verify the fix for defect 430304.

All test code passes on all platforms.

Defects fixed

-------------

ER5 defect EDN 430304: Failure to compact a CDictionaryStore no longer masks a successful CommitL().

Rebuilt with MSVC++ 5.0 Service Pack 3 to ensure good WINS release builds.

Boiler-plated the source code using the SysDoc tool.

Changes

-------

All literal descriptors now use _LIT(), saving a few hundred bytes

All uses of __DECLARE_NAME() have been removed (deprecated)

Release 060 - Graham Asher - 23rd November 1998

===============================================

ER6 only, hence the jump in release numbers.

In the Unicode builds only, 16-bit descriptors are compressed on externalisation, and decompressed on internalisation, using the Standard Compression Scheme for Unicode. The compression and expansion functionality has been moved here from ETEXT, tidied up, and made public by way of exported functions of TUnicodeCompressor and TUnicodeExpander. Prospective clients so far are ETEXT and DBMS. The new header file for the compression and expansion is s32ucmp.h.

Version 1.05.050

================

(Made by AjThoelke, 28 October 1998)

Binary Compatibility

--------------------

Only WINS REL, MARM REL and MARM DEB releases are binary compatible with 049

WINS DEB is now BC with WINS REL

WINS UREL is BC with WINS UDEB

MARM UREL is BC with MARM UDEB

Build

-----

ER5 compatibility components:

E32TOOLS 095

E32TOOLP 096

E32 release 156

F32 release 122

ARM narrow release size is 70056 bytes (68.4K), as reported from ROMBUILD.

WINS releases built using MSVC++ 5.0, debug databases are now incompatible with

earlier versions of the IDE.

Changes

-------

1.	Implemented phase 3 of Epoc32 Proposal SW1-87. The CleanupXxxPushL()

	template classes and functions in s32strm.h have been removed, as

	they are included in e32base.h. STORE header files are no longer

	required to provide this functionality.

2.	A new UID has been allocated for the STORE unicode DLL: 0x10003B0D

Version 1.02.049

================

(Made by AjThoelke, 11 June 1998)

This release is primarily to provide MSVC 5.0 build compatibility

Binary Compatibility

--------------------

All binary releasables are exactly the 048 releasables as the changes

have no impact on the code generated. This fact was verified by

validation of objects rebuilt with the new header files.

Hence, fully BC with 048, and no test code has been run, as the binaries

have already been tested for 048.

Build

-----

E32 release 126, for debug/release compatibility and Security framework

F32 release 095

E32TOOLS 089

ARM narrow release size is 70020 bytes (68.4K), as reported from ROMBUILD.

The build commands no longer output to the console, but direct all output

into a log file: \dbms\bmake\<platfrom>.<build>.log. If a build fails these

will contain the compiler/linker errors, If the build succeeds these will

contain any warnings.

Fixed

-----

1.	SW1-66: s32btree.h and s32cont.h contained various template

	specialisations which had not been treated for MSVC 5.0 changes.

	TEMPLATE_SPECIALIZATION added to the affected classes.

2.	Implemented phase 1 of Epoc32 Proposal SW1-87. The CleanupXxxPushL()

	template classes and functions in s32strm.h are protected by an

	include guard macro __EPOC_CLEANUP_SUPPORT__. A future release of E32

	will place this functionality in a E32 header.

Version 1.02.048

================

(Made by AjThoelke, 5 May 1998)

Binary Compatibility

--------------------

All builds are forwards and backwards compatible with STORE 047

All test code has been run against all compatible builds

Build

-----

E32 release 126, for debug/release compatibility and Security framework

F32 release 095

E32TOOLS 089

ARM narrow release size is 70020 bytes (68.4K), as reported from ROMBUILD.

Fixed

-----

*	TStreamBuf::DoReadL() and DoWriteL() members had an over aggressive

	debug assertion which checked the state of the other buffer. The

	assertion also happens to fail for a read-only buffer which lives above

	address 0x80000000, e.g. in a fixed process.

	The assertion has been changed to correctly allow for read-only or

	write-only stream buffer.

*	Mis-ordering of two inline functions in an internal header resulted in

	non-inlining. This results in a slightly smaller DLL.

Version 1.02.047

================

(Made by AjThoelke, 19 February 1998)

Binary Compatibility

--------------------

All WINS builds are backwards BC with STORE 046.

MARM REL builds are backwards BC with STORE 046.

MARM debug builds are NOT binary compatible with STORE 046, in order to

introduce compatibility with the corresponding STORE 047 release component.

If you are building a release/debug compatible MARM component you must use

at least E32 125, F32 95 and STORE 047.

New exports have been added to provide the RSecureStorePagePool class in

s32crypt.h. If you require this class you must use STORE 047 (and thus

E32 125 and F32 95).

All test code has been run against all compatible builds

Build

-----

E32 release 125, for debug/release compatibility and Security framework

F32 release 095

E32TOOLS 089

ARM narrow release size is 70052 bytes (68.4K), as reported from ROMBUILD.

MAKMAKE is now used throughout STORE. The new BMAKE directory contains the batch

file (bld.bat), makefiles and mmp files to build STORE. BWINS and BMARM now just

contain the export definitions files.

STORE can still be built using the mnt verbs, or by invoking BLD in the BMAKE

directory. Invoking BLD without parameters gives the basic syntax used.

Test code is built either in each test code sub-project using bld.bat or the

makefile, or using mnt.cmd from the group as before to build all test code.

Fixed

-----

*	RFrame16Buf::ReadL() could corrupt the internal CPermanentFileStore

	state if it was called after having already indicated that there was no

	more data to read. Fixed by reseting the read position if the read

	terminator has been read.

	This is extremely unlikely to affect current code, as it only occurs for

	streams in Permenent File Stores which end exactly on a 16K boundary and

	which have ReadL() called many times after the end of stream is reached.

	Fix #3 below was introduced as a result.

*	TDesBuf::Consolidate() would fail with a descriptor overflow panic if

	it was operating as read-only and the descriptor data address was in the

	upper half of memory, i.e. address>=0x80000000.

	This is unlikely to affect current code, as user data (until E32 121)

	lived int he lower half of memory. There is a workaround, if required:

	set the stream buffer to read/write mode.

*	Encryption filters were very eager to read data from the source stream

	when the request could be fulfilled from the filter's output buffer.

	In these cases they now make no read request on the source. This

	significantly improves performance of the decryption filter when the

	end of a stream is reached.

New stuff

---------

*	Class RSecureStorePagePool in s32crypt.h. This relies on a bounded

	encryption algorithm and a new framework class from E32[124]. It has the

	same behaviour as RStorePagePool, except that all pages are encrypted

	using the supplied key.

*	Debug and Release builds are compatible. The inline debug assertions

	will still operate when a DEB client is run against a REL STORE.

	This will not affect the runtime speed or size of a REL client.

	One upshot of this is that the CPageCache statistics are not enabled for

	either REL or DEB builds. A custom STORE would be required were these

	required for cache-size research.

Version 1.01.046

================

(Made by AjThoelke, 2 October 1997)

Build

E32 release 111, for the TEMPLATE _SPECIALIZATION macro used for VC++ 5.0 support

F32 release 074 (Platform 001)

E32TOOLS 077

ARM narrow release size is 68892 bytes (67.3K), as reported from ROMBUILD.

Fixed

*	SW3-1555. MSVC++ 5.0 compatibility tweaks added to relevant headers.

*	SW3-1707. CDictionaryFileStore has a new algorithm for dealing with

	contention for the same file across multiple threads. It can now

	typically handle 20 equal priority threads, previously only 4. In the

	worst case, when the file is locked open, the code will return failure

	in approx. 1 second.

	Test code for contention has been added to T_DICFS.CPP.

*	Some debug code in TStreamMark::IsTracking() and TStreamMark::Track()

	was not working for data addresses above 0x80000000. This has not

	affected any code so far as no platform used such data addresses...

	until now. This is not a BC issue as this is not present in release

	build.

Version 1.00.045

================

(Made by AjThoelke, 4 July 1997)

1.	Built using Platform 001 releases of E32 and F32; used E32TOOLS/074

	ARM narrow release size is 68676 bytes (67.1K), as reported from ROMBUILD.

2.	Fixed SW3-1579, by adjusting reclaimation state machine to return

	more often when caclulating stream lengths.

Version 1.00.044

================

(Made by AjThoelke, 28 May 1997)

1.	Built using Platform 001 releases of E32 and F32; used E32TOOLS/067

	ARM narrow release size is 68636 bytes (67K), as reported from ROMBUILD.

2.	Fixed MNT VALID: needed -e32 in pediff command line.

Version 1.00.043

================

(Made by AjThoelke, 16 May 1997)

1.	Built using Platform releases of E32 and F32; used E32TOOLS/066

	ARM narrow release size is 68636 bytes (67K), as reported from ROMBUILD.

2.	Binary Compatibility

	Backwards binary compatible with Platform release 042.

	Three new exports in this release:

	from s32share.h

	TInt TStreamMark::ReadL(TStreamExchange& aHost,TDes8& aDes,TRequestStatus& aStatus);

	TInt TStreamMark::WriteL(TStreamExchange& aHost,const TDesC8& aDes,TRequestStatus& aStatus);

	from s32stor.h

	TBool CDictionaryStore::IsNullL() const;

	The first two were declared as IMPORT_C in the platform release, but

	were not exported. The third is a new function in the header file.

	If you require any of these exports you must build against this release

	and state your dependency on STORE 043 explicitly in your release notes.

	Currently there are no components which do so.

3.	Removed Name builds from the BWINS project make file.

4.	Added map files to MARM releaseables

5.	Fixed SW3-134. Two functions in TStreamMark declared as IMPORT_C did not

	exist. These have been correctly implemented and exported.

6.	Fixed SW3-182. Added a new function

	TBool IsNullL() const;

	to CDictionaryStore to complement CStreamDictionary::IsNull(). This returns

	true when the dictionary store is the null mapping:

		<any uid> -> empty stream

7.	Adjusted logo text in PFSDUMP "EPOC/32" -> "EPOC32", copyright date, and

	full version number "1.00(build 043)"

Version 0.06.042

================

(Made by AjThoelke, 16 April 1997)

1).	Built using E32TOOLS/063, E32/098 and F32/068. ARM narrow release size

	is 68532 bytes (67K), as reported from ROMBUILD.

	Binary compatible with 041.

	File compatible with 041.

2.	MARM releasables conform to the new Uid scheme:

		Dynamic Library : Shared Library : ESTOR

	So MARM requires E32 098 for running anything other than narrow release

	builds.

3.	The suffix "Uid" has been added to the KDirectFileStoreLayout and

	KPermanentFileStoreLayout TUid constants. Binary, but not source,

	compatible.

	const TInt KDirectFileStoreLayoutUidValue has also been added, similarly

	for KPermanentFileStoreLayoutUidValue.

4.	Added member TBool CStreamDictionary::IsNull() const

	This returns whether a dictionary is the null mapping:

		<any uid> -> KNullStreamId

	i.e. this is false if it contains a non-null mapping for at least one

	Uid.

5.	The system dictionary file store now has the politically correct name:

	C:\System\System.ini

Version 0.06.041

================

(Made by AjThoelke, 9 April 1997)

1).	Built using E32TOOLS/059, E32/096 and F32/065. ARM narrow release size

	is 68492 bytes (67K), as reported from ROMBUILD.

	Binary compatible with 040.

	File compatible with 040.

2).	MARM releasables are now pre-PETRAN'd, so you can remove those UID

	settings from your .oby and .iby files.

3).	Two new static members have been added to CDictionaryFileStore:

	CDictionaryFileStore* SystemL[C](RFs&)

	This opens (creating if necessary) the system dictionary file (INI
