* contrib/rdd_ads/ads1.c
* contrib/rdd_ads/rddads.h
+ Changed fieldname max length handling,
it is now a workarea property. (set by the RDD)
(in ADS, this is just a patch)
! contrib/btree/hb_BTree.c
* struct hb_btree pStrCompare function pointer changed to use the size_t
type for the third param, to coincide with ChangeLog 2002-07-14 14:14 UTC+0500
* contrib/btree/hb_btree.api
+ extern "C"
* rename nFlags to ulFlags
+ declaration for hb_BTreeDataItem()
* declaration for hb_BTreeInsert() to use a PHB_ITEM vs LONG
* contrib/btree/hb_btree.ch
- comments from around 'inmemory' definition
* contrib/btree/test/test.prg
+ code to test in-memory tree, including passing floats vs longs
* contrib/btree/test/ctest.c
! a SEEK call that was incorrectly failing because the
DATA param passed as 0
* hb_BTreeInsert() calls to use new form (PHB_ITEM vs long)
* contrib/btree/hb_btree.c
; the following warnings are reported by BCC (thanks Alexander):
Suspicious pointer conversion in function hb_BTreeNew & hb_BTreeOpen
pBTree->pStrCompare = strncmp;
Parameter 'ulFlags' is never used in function hb_BTreeOpen
- defintion and use of DBG() macro
+ extern "C" ifdef'd
- comments from around 'inmemory' definition
* renamed nFlags to ulFlags, lFlags to ulFlags, position to iPosition
* hb_btreenew [hi level] - when flag contains HB_BTREE_INMEMORY,
first
parameter is ignored
* hb_btreenew [lo level] - when flag contains HB_BTREE_INMEMORY,
dont
try to open the file, etc, and clear necessary fields
* hb_btreeclose [lo level] - close file and release file name only when
necessary
* only call HeaderWrite() when not in-memory tree
+ ioOneBufferAlloc() - allocate one ioBuffer_T block, called by
ioBufferAlloc(), and Grow() when in-memory
* Grow() in-memory - add a page to the link list
+ Prune() in-memory - added code to remove a page from the link list
* (assorted) IsDirty flag is assigned the tree property IsDirtyFlagAssignment,
so that in-memory trees never fire the write methods (ie. always false)
* hb_BTreeGoTop(), hb_BTreeGoBottom() [lo-level]
+ bug fix: preserve last node found
+ if tree is empty, clear key/data, else retrieve selected key/data
* ioBufferRead() - moved IsDirty reset within "if ( IsDirty )" block
* ioBufferScan() - call ioBufferRead() when not in-memory tree
- SearchNode() redundant BufferRelease() and return statement
- enum ExceptionTypes (not used)
- Buffer_T typedef struct, incorporating into the ioBuffer_T typedef struct
* hb_KeyData_T: replaced lData with a union lData/pData
+ definition for hb_BTreeDataItem()
* definition for hb_BTreeInsert() to use a PHB_ITEM vs LONG
* hb_btreeinsert() [hi-level] accepts only number for file i/o and
any data type for in-memory
- macro SETKEYDATA(), placing equivalent code into hb_BTreeInsert()
+ Prune() - release individial items and then the page itself
! CountAdj() last param should have been SHORT not USHORT
; RecDelete() moved the inline assignment & comparision around to remove
the b32 warning
TODO: find a solution to the 'Suspicious pointer conversion in function
hb_BTreeNew & hb_BTreeOpen' [strncmp() & hb_strncmp()]
TODO: impliment ulFlags within hb_btreeopen() - see warning above
- clear im-memory flag
- get unique flag from file header
* contrib/btree/doc/hb_btree.txt
* spelling corrections
* clarified use of HB_BTREE_INMEMORY flag with hb_BTreeNew() API
! corrected type of pBTree params, from 'hb_BTree *' to 'struct hb_BTree *'
+ definition for hb_BTreeDataItem()
* clarified use of data param and data return value
