Important notes (changes that may break existing code)
======================================================
- Updated TkbmMWOnMessageToSpoke,
TkbmMWOnMessageToSpokeDeliveryFailed,
TkbmMWOnMessageToSpokeDeliverySuccess events to include the
queue.
New stuff
=========
- Added TkbmMWScheduler in new unit kbmMWSceduler.pas (Ent)
for precise and relaxed event scheduling.
System scheduler are available via Scheduler instance.
Check demo for examples of use.
- Added TkbmMWMemSQL which is an extension to the TkbmMemSQL
class (Ent).
It adds syntax for:
- Defining fieldtypes:
SELECT field1 as 'field1->INT'... The field types can be
INT,VARCHAR2(n),VARCHAR(n),CHAR(n),BOOL,
AUTOINC,FLOAT,NUMERIC,REAL,DATETIME,
DATE,TIME,LARGEINT,INT64,BLOB,GRAPHIC,
CLOB,TEXT(n),CURRENCY,WORD,MEMO,WIDEMEMO,GUID
- Operating on XML and JSON data registered with SQL
component:
SELECT owner AS 'someowner->TEXT(3)',bid,quantity AS
'dato->DATE'
FROM auctions
SUBSET '/alliance/auctions/.*'
ORDER BY bid,owner
SELECT XMLAttr(value,'//datas','name') AS
'name->TEXT(20)', value
FROM data TEXT(XML,'<datas
name="hello"><data><value>10</value></data><data><value>20</value></data>>/datas>')
SUBSET '^/datas/data/$'
- Operating on inline XML:
SELECT value
FROM data
TEXT(XML,'<data><value>10</value><value>20</value></data>')
SUBSET '/data/value'
ORDER BY value
- Operating on inline JSON:
SELECT value
FROM data TEXT(JSON,'{"data":[{"value":10},{"value":20}]}')
SUBSET '/data/.*'
ORDER BY value
- Loading data from external CSV (SF_CSV) or
binary (SF_BIN) files:
SELECT [species no], common_name
FROM biolife FILE(SF_CSV,'.iolife.csv')
ORDER BY common_name
- Loading data from external XML and JSON files:
SELECT owner,bid,quantity
FROM auctionsfile FILE(JSON,'.auctions.json')
SUBSET '/alliance/auctions/.*'
ORDER BY bid,owner
- Outputting results as binary (SF_BIN), CSV (SF_CSV), XML
(SF_XML) and JSON (SF_JSON) files:
SELECT fld2 AS Field2, fld3, sum(fld5) AS fld5,
Sum(fld2) AS SomeField1, Sum(fld3) AS SomeField2
FROM table1
GROUP BY Field2, fld3
OUTPUT FILE(SF_JSON,'.output.json','nodef')
- Outputting results as CSV, XML and JSON text string:
SELECT fld2 AS Field2, fld3, sum(fld5) AS fld5,
Sum(fld2) AS SomeField1, Sum(fld3) AS SomeField2
FROM table1
GROUP BY Field2, fld3
OUTPUT TEXT(SF_XML,'nodef')
Output formats supports various options:
- SF_CSV supports: nodef, quote=X, fielddelimiter=X,
recorddelimiter=X, truestring=xxx, falsestring=xxx,
noheader, onlyquotestrings, usedisplayname
- SF_JSON supports: nodef, rowid, datanode, memoasstring,
nonull, bmp, png (not MacOS), jpeg (not MacOS),
rowidname=xxx, dataname=xxx, definitionname=xxx
- SF_XML supports: nodef, rowid, datanode,
datasetname=xxx, rowidname=xxx,
fieldname=xxx, dataname=xxx, definitionname=xxx
- SF_BIN supports: nodef
Check demo for examples of use.
- Added kbmMWSQLXMLAPI.pas, kbmMWSQLJSONAPI.pas units (Ent) to
support above.
- Added XmlNode and XmlAttr in kbmMWSQLXMLFunc.pas for XML
specific functions useful when running SQL on XML documents.
- Added new QoS flag to WIB messages:
KBMMW_TRANSPORT_QOS_CONFIRMED_DELIVERY
If set on a message, the message will need to be acknowledged
by receiver before its committed in senders queue. In
practice receiver bulk acknowledges received messages at an
interval and/or message count.
- Upped subject header version to 4.
Define KBMMW_SUBJECTHEADER_V3_COMPAT
to generate messages compatible with v3.
Notice that QoS must handshake flag require v4.
- Added AOptions:TkbmMWMessageOptions to all message creating
methods/functions when WIB is enabled. Provides access to
defining QoS flags for a message.
- Added InboundRetransmitTotal, OutboundRetransmitTotal,
AutoSetupHandshakeSubscription,
SendEvent, SendPrioritizedEvent, InboundAckHandler,
OutboundAckHandler
to client and server messaging transports.
- Added Flush method to TkbmMWFileStoreMessageQueue to force
write of cached data to file.
- Added TkbmMWWeekDay type to kbmMWDateTime.pas unit.
- Added global function kbmMWXMLDataType2VariantType to
kbmMWXML.pas. Returns variant datatype based on XML datatype.
- Updated Load/Save functions in kbmMWXML to configure to
stream/not stream BOM markers.
- Changed AttribByNameAsDuration in kbmMWXML to return
TkbmMWDuration value instead of TkbmMWDateTime.
- Added kbmMWAddHop, kbmMWExtractLastHop, kbmMWHopCount,
kbmMWPeerID, kbmMWExtractPeerID,
kbmMWGenerateHandshakeSubscriptionSubject,
kbmMWGenerateHandshakeSubject methods to kbmMWSubjectUtils.
- Added CreateResponseMessage, CreateRequestMessage,
CreateServiceCallMessage methods to WIB.
- Added optional ASilent:boolean=false argument to
CommitMessagePop, RollbackMessagePop, RejectMessage
If true, will not raise exception if message do not exist.
Also now returns true or false depending on if operation
suceeded.
- Added OnStats event to TkbmMWServer. Is called whenever there
is a statistics update.
- Added Load/Save methods for file and stream based storage in
TkbmMWXMLAuthorizationStorage.
- Added mwldtWeb to TkbmMWLogDataType.
- Added Enabled:boolean property to IkbmMWLogManager and
implementing classes.
- Added LogWeb method to IkbmMWLog interface and implementing
classes. Logs data in an Apache compatible way.
- Added function FormatWebLogRecord to IkbmMWLog and
implementing classes. It returns an Apacke compatible log
string to be used with LogWeb.
- Extensively updated TkbmMWInterval in kbmMWDateTime.pas unit
to be nullable, compile numeric value that can be compared
with another interval instance's numeric value to test for
which interval is longer, multiple overloaded constructors,
millisecond support, Compare function.
Supports fractional and overrun values for years, months,
days, hours, minutes, seconds and weeks.
- Added TkbmMWInterval as alias to TkbmMWDuration.
- Added Compare and Clear methods to TkbmMWDateTime.
- Added Incxxx methods to TkbmMWDateTime taking fractional and
overrun values.

Newly created empty object or array will be added to array
and returned for developer to populate.
- Added InsertArray and InsertObject to TkbmMWJSONArray.
- Added AAutoCreateChildren:boolean (default true) argument to
constructor of TkbmMWJSONObject. Controls what happens when
accessing properties AsArray or AsObject when no array or
object is available under the given name. If
AutoCreateChildren is false, nil will be returned or an
exception raised, else new objects/arrays are created
automatically.
- Added option to stream BOM in TkbmMWJSONStreamer.
- Added Load/Save UTF8 file and stream access methods to
TkbmMWJSONStreamer.
- Added FileStoreOptions property to
TkbmMWFileStoreMessageQueue which
controls what happens when queue is closed. Can be
mwfsoDeleteOnClose, mwfsoDeleteOnCloseWh or nothing.
- Added TkbmMWCustomThreadHashList,
TkbmMWHashStringInterfaceList
and TkbmMWThreadHashStringInterfaceList to kbmMWGlobal.pas.

transports.
Changes/minor additions
=======================
- Added APostSubject:string='' argument to all message
producing methods/functions to allow postfixing additional
data to the standard subjects like REQ/RES etc. to allow for
easier custom receiving end filtering based on custom data.
- Added AClosing:boolean = true argument to Flush method of
TkbmMWBufferedFileStream.
If true (default) flush is expected to optionally (on
Windows) truncate file to the actual size it has, not the
sector based size. Call with closing false to just flush the
cache to the file.
- Added GetMimeTypeExt(const AExt:string):string and
GetCharSetExt(const AExt:string):string to
kbmMWCustomHTTPService.pas. Allows for providing a file
extension (including dot) instead of a file path.
- Improved FastCGI communication with FastCGI server to more
reliably detect environment header.
- Changed so SubjectHeader.Hops always initially includes
sender.
- Changed TkbmMWAuthorizationUTCTimeConstraint to use
TkbmMWWeekDay for week day constraints.
- Updated timezone list in kbmMWDateTime.
- Updated TkbmMWOnMessageToSpoke,
TkbmMWOnMessageToSpokeDeliveryFailed,
TkbmMWOnMessageToSpokeDeliverySuccess events to include the
queue.
Fixes
=====
- Fixed leak of TkbmMWInnerThread on shutdown.
- Fixed thread pool bugs.
- Fixed Remote Desktop compilation issues in pre XE6.
- Fixed FIB compilation issues.
- Fixed UniDAC compilation issues and missing Options property.
- Fixed so a response message has same QoS as the request
message.
- Fixed TkbmMWAuthorizationLogin.Touch to touch using UTC, not
local time, which would result in actor being timed
incorrectly out.
- Fixed leak of TFileStream/TkbmMWBufferedFileStream in
kbmMWDebugTdsFile.pas and kbmMWDebugMapFile.pas when loading
of TDS/MAP file excepted (for example by being in use by the
Delphi debugger when running app in debug mode).
- Fixed StreamSec TLS plugin compilation.
- Fixed bugs in
TkbmMWHTTPTransportStreamHelper.HTTPBuildCustomResponseHeader.
- Fixed bugs in SQLite adapter
