- Change History (most recent first):
- <MacOSX> 3/2/98 djb Fix extents corruption bug in MoveExtents (radar #2309434).
- <MacOSX> 11/20/98 djb Add support for UTF-8 names.
- <MacOSX> 4/2/98 djb Switch over to real BTree interface in MoveExtents and DeleteExtents.
- <MacOSX> 3/31/98 djb Sync up with final HFSVolumes.h header file.
-
- <CS21> 11/17/97 djb PrepareInputName routine now returns an error.
- <CS20> 11/13/97 djb Radar #2001699 ResolveFileID needs to use CMNotFound error.
- <CS19> 10/31/97 JL #2000184 - CreateFileThreadID and ExchangeFiles now return the
- WDCBRecPtr or NULL for external file systems. ExchangeFiles no
- longer returns length of FCB table to caller since that wasn't
- ever needed.
- <18> 10/23/97 DSH 1685058, Fix ExchangeFiles by invalidating the node cache before
- switching the files.
- <CS17> 10/19/97 msd Bug 1684586. GetCatInfo and SetCatInfo use only contentModDate.
- <CS16> 10/16/97 DSH Return badFidErr in ResolveFileID if LocateCatalogThread fails
- <CS15> 10/15/97 DSH CreateFileThreadID(), remap btExists to fidExists.
- <CS14> 9/7/97 djb Turn off some DebugStr calls.
- <CS13> 9/4/97 msd Remove call to PropertyExchangeObjects.
- <CS12> 8/14/97 djb Remove hard link support.
- <CS11> 7/18/97 msd Include LowMemPriv.h.
- <CS10> 7/16/97 DSH FilesInternal.i renamed FileMgrInternal.i to avoid name
- collision
- <CS9> 7/8/97 DSH Loading PrecompiledHeaders from define passed in on C line
- <CS8> 6/24/97 djb Add hard link support to ResolveFileID and CreateFileIDRef.
- <CS7> 6/20/97 msd Use contentModDate and attributeModDate fields instead of
- modifyDate.
- <CS6> 6/13/97 djb Switch over from PrepareOutputName to ConvertUnicodeToHFSName.
- PrepareInputName now takes an encoding.
- <CS5> 5/28/97 msd Move the declaration of FindFileName to FilesInternal.i.
- <CS4> 5/19/97 djb No longer need to invalidate vcbDirIDM field.
- <CS3> 5/16/97 msd In ExchangeFiles, change srcNamePtr from char * to StringPtr
- (fixes warnings).
- <CS2> 4/28/97 djb (DSH) Added VolumeWritable check back into CreateFileIDThread.
- <CS1> 4/24/97 djb first checked in
- <HFS23> 4/11/97 DSH Use extended VCB fields catalogRefNum, and extentsRefNum.
- <HFS22> 4/9/97 msd Rewrite CreateFileThreadID so that it properly handles
- pathnames, and doesn't overwrite the ioNamePtr. The data field
- of FindFileNameGlueRec points to a CatalogNodeData, not
- CatalogRecord.
- <HFS21> 4/4/97 djb Get in sync with volume format changes.
- <HFS20> 3/31/97 djb Change ClearMem to ClearMemory.
- <HFS19> 3/17/97 DSH C_FlushCache prototype to FilesInternal.h
- <HFS18> 3/5/97 msd ExchangeFiles needs to call PropertyExchangeObjects.
- <HFS17> 2/13/97 msd Fix MoveExtents and DeleteExtents to work with HFS+ extent
- records.
- <HFS16> 1/31/97 msd In MoveExtents, when a record isn't found and you want the next
- record in order, use the "next record" offset = 1 instead of
- "current record" offset = 0. DeleteExtents would always exit
- without doing anything because it was searching for an invalid
- key. Removed several DebugStrs that were used as cheap code
- coverage.
- <HFS15> 1/15/97 DSH Resolve wasn't passing the name back for HFS
- <HFS14> 1/13/97 djb LocateCatalogThread now passes back the thread record size.
- <HFS13> 1/11/97 DSH HFS+, fixed some Unicode/Pascal strings related bugs for use on
- HFS+ volumes.
- <HFS12> 1/9/97 DSH Fix ExchangeFiles extents
- <HFS11> 1/6/97 DSH pass VCB in CloseFile() routine.
- <HFS10> 1/6/97 djb Fixed ResolveFileID - it was not returning a directory ID!
- <HFS9> 1/3/97 msd Fix prototype for C_FlushCache. Fix prototype for
- TrashFileBlocks.
- <HFS8> 1/3/97 djb Integrate latest HFSVolumesPriv.h changes.
- <HFS7> 1/2/97 DSH C port of ExchangeFileIDs
- <HFS6> 12/20/96 djb Fixed bug in CreateFileID.
- <HFS5> 12/19/96 DSH All refs to VCB are now refs to ExtendedVCB
- <HFS4> 12/19/96 msd Use kFileThreadExistsMask (from HFSVolumesPriv.h) instead of
- kFileThreadMask (from FilesInternal.h) since the latter was
- incorrectly defined and has now been removed.
- <HFS3> 12/19/96 djb Updated for new B-tree Manager interface.
- <HFS2> 12/18/96 msd GetFileThreadID was using a bitwise-OR (|) instead of
- bitwise-AND (&) to test for a bit being set.
- <HFS1> 12/12/96 DSH first checked in
