12000-01-02  a sun  <asun@asun.cobalt.com>
2
3	* file.c (hfs_get_block): added hfs_get_block for regular files.
4
51999-04-12  a sun  <asun@hecate.darksunrising.blah>
6
7	* file_hdr.c (hdr_read): added rootinfo behaviour for DID header.
8
91999-04-11  a sun  <asun@hecate.darksunrising.blah>
10
11	* super.c (parse_options): added s_version so that we can select
12	between different versions of the same layout.
13
141999-04-05  a sun  <asun@hecate.darksunrising.blah>
15
16	* linux/hfs_fs.h: unified netatalk and appledouble header format.
17	added in all of the AFP attribute bits.
18
19	* file_hdr.c: added netatalk appledouble v2 compatible headers.
20
211999-01-30  a sun  <asun@hecate.darksunrising.blah>
22
23	* catalog.c (hfs_cat_move): fixed corruption problem with
24	renames.
25
261999-01-27  a sun  <asun@hecate.darksunrising.blah>
27
28	* file_hdr.c (get/set_dates): got rid of broken afpd times. NOTE:
29	you must use netatalk-1.4b2+asun2.1.2 or newer for this.
30
311998-12-20  a sun  <asun@hecate.darksunrising.blah>
32
33	* bdelete.c (del_root): assign bthLNode and bthFNode only if the
34	root node becomes a leaf node. Disk First Aid no longer
35	complains. Norton Utilities, of course, has decided that it
36	doesn't like the root node number. bleah. i think that it might be
37	due to Norton Utilities not expecting the root node to have moved.
38
391998-12-16  a sun  <asun@hecate.darksunrising.blah>
40
41	* sysdep.c (hfs_revalidate_dentry): fix inode dates when there's a
42	timezone change.
43
441998-12-15  root  <root@hecate.darksunrising.blah>
45
46	* extent.c (new_extent): expand block size variables to handle
47	u32.
48
49	* mdb.c (hfs_mdb_get): AlBlkSiz shouldn't be capped at 65535. we
50	should be able to handle much larger volumes now.
51
521998-11-21  a sun  <asun@hecate.darksunrising.blah>
53
54	* hfs_sysdep.h, hfs_fs.h: added hfs_from_utc/to_utc to deal with
55	date differences on hfs formatted media.
56
57	NOTE: hfs extended keeps everything in utc, so we'll need to deal
58	with that when appropriate.
59
601998-11-12  a sun  <asun@hecate.darksunrising.blah>
61
62	* extent.c (shrink_fork): added some lock_bitmap/unlock_bitmap's
63	to protect hfs_clear_vbm_bits. we should no longer have problems
64	with free_ablocks wrapping around.
65
661998-11-02  a sun  <asun@hecate.darksunrising.blah>
67
68	* mdb.c (hfs_mdb_get): plugged up an mdb failed initialization
69	leak.
70
711998-10-31  a sun  <asun@hecate.darksunrising.blah>
72
73	* version.c (hfs_version): bumped to version 0.96.
74
75	* mdb.c (hfs_mdb_commit): you only write out the alternate MDB
76	when the catalog or extents overflow files grow. that just leaves
77	the btree corruption problems. bleah (whilst deleting a bunch of
78	files, more of the btree can get pruned away than desired).
79
801998-10-30  a sun  <asun@hecate.darksunrising.blah>
81
82	* dir.c: fixed a bunch of silliness with deletions. make sure to
83	zero out stuff and set mark_inode_dirty().
84
851998-10-29  a sun  <asun@hecate.darksunrising.blah>
86
87	* string.c (hfs_strcmp, hfs_streq, hfs_strhash): converted them to
88	take name/len arguments instead of hfs_name to reduce copying.
89
90	* dir.c, dir_nat.c, dir_cap.c, dir_dbl.c, sysdep.c: modified
91	relevant areas to reflect string.c changes.
92
931998-10-28  a sun  <asun@hecate.darksunrising.blah>
94
95	* hfs.h (hfs_lookup_dentry): oh my. more silliness. make sure to
96	have the d_lookup use the same hash value as the one generated by
97	hfs_hash_dentry. i also changed the argument order.
98	(hfs_drop_special): change the argument order to be more in line
99	with what the dcache stuff looks like.
100
101	* sysdep.c (hfs_compare_dentry): the compare was returning the
102	wrong value for correct matches and causing all sorts of
103	mischief. this fixes both directory counts and mounting on top of
104	hfs volumes.
105
106	* file.c, file_cap.c, file_hdr.c: added mark_inode_dirty()'s in
107	the relevant places.
108
1091998-10-11  root  <asun@hecate.darksunrising.blah>
110
111	* mdb.c (hfs_mdb_get): moved initialization of mdb->entry_dirty
112	list to here to deal with trying to read a bad hfs volume.
113
1141998-10-10  a sun  <asun@zoology.washington.edu>
115
116	* inode.c, catalog.c, dir_*.c, sysdep.c: parts of the dcache
117	conversion didn't get done properly. specifically, i forgot to
118	move the hfs_cat_puts into the right place. that's fixed now.
119
1201998-09-11  a sun  <asun@purgatorius.zoology.washington.edu>
121
122	* mdb.c: altered mdb struct to reflect hfs plus usage.
123
1241998-08-27  a sun  <asun@purgatorius.zoology.washington.edu>
125
126	* file.c, file_hdr.c, file_cap.c: dealt with the remaining
127	copy_to/from_user() error cases.
128
1291998-08-26  a sun  <asun@purgatorius.zoology.washington.edu>
130
131	* super.c (hfs_read_super): fixed to deal with cdroms. why doesn't
132	the cdrom layer call the partition table code?
133
134Wed Jan 21 14:04:26 1998  a sun  <asun@zoology.washington.edu>
135
136	* inode.c, sysdep.c
137	use d_iput to uncache dentry from catalog entry instead of relying
138	on put_inode. no more NULL pointer dereferences!
139
140	* catalog.c
141	cleaned up hfs_cat_put a little.
142
143	ISSUES (non-fatal): mv dir dir2 while creating files in dir screws
144	                    up directory counts.
145
146			    deletion using netatalk screws up directory
147 			    counts.
148
149Thu Jan 15 19:14:28 1998  a sun  <asun@zoology.washington.edu>
150
151	* catalog.c
152	make deletion happen when requested instead of waiting until
153	an hfs_cat_put as the dcache can hold onto entries for quite
154	some time.
155
156Wed Jan 14 14:43:16 1998  a sun  <asun@zoology.washington.edu>
157
158	* catalog.c
159	the current catalog allocation scheme allocates
160	PAGE_SIZE/sizeof(struct hfs_cat_entry) entries at a time and keeps
161	a pool of free entries up to this allocation unit * 8.
162
163	* inode.c
164	make sure to always hfs_cat_put if hfs_iget is going to return
165	NULL.
166
167	* string.c, catalog.c
168	use linux' hashing method to generate hashes. the old hashing was
169 	getting collisions. catalog.c also has a larger hash table to
170 	prevent collisions.
171
172Tue Jan 13 13:06:01 1998  a sun  <asun@zoology.washington.edu>
173
174	* version.c
175	bumped to 0.95+asun3
176
177	* catalog.c
178	re-wrote to dynamically allocate/delete catalog entries. on a 486,
179	entries fit into the size-256 slab.
180
181Wed Jan  7 19:33:33 1998  a sun  <asun@zoology.washington.edu>
182
183	* inode.c
184	don't hfs_cat_put gratuitously in hfs_iget. that's a bad
185 	idea and results in screwed up entry counts.
186
187Tue Jan  6 14:38:24 1998  a sun  <asun@zoology.washington.edu>
188
189	* version.c
190	changed it to 0.95+asun2
191
192	* sysdep.c
193	altered catalog entry pruning to make sure that an iput
194	gets done. for some reason, shrink_dcache_parent wasn't
195	doing it.
196
197	* catalog.c
198	added a global dirty list to check for pruning.
199
200Tue Jan  6 12:29:52 1998  a sun  <asun@zoology.washington.edu>
201
202	* catalog.c
203	re-wrote it to be similar to 2.1.x inode.c. this should
204 	at least make catalog.c SMP safe.
205
206	* hfs.h, linux/hfs_fs.h
207	moved dentry operations into hfs.h. these probably should
208	be moved somewhere else.
209
210	* super.c, dir_cap.c, dir_nat.c, dir_dbl.c, sysdep.c
211	added dentry ops to hash everything to lowercase.
212
213Sun Dec 28 22:48:53 1997  a sun  <asun@zoology.washington.edu>
214
215	* sysdep.c, catalog.c, hfs.h
216	as a temporary workaround until catalog.c gets re-written,
217	i flush the dcache if we need more entries.
218
219Fri Dec 19 15:11:21 1997  a sun  <asun@zoology.washington.edu>
220
221	* dir_dbl.c
222	statically allocate tmp_name instead of doing it dynamically.
223
224	NOTE: well, those pesky hfs_cat_put messages still aren't gone. in
225	addition, catalog.c needs to be modified to free up some entries
226	when the cache gets filled up.
227
228Sun Dec 14 11:51:11 1997  a sun  <asun@zoology.washington.edu>
229
230	* linux/hfs_fs.h
231	moved the dentry stuff into within the #ifdef __KERNEL__
232	part of hfs_fs.h and cleaned up a little.
233
234Sun Dec 14 11:24:54 1997  a sun  <asun@zoology.washington.edu>
235
236	* dir.c
237	changed hfs_rename to delete all old dentries. hfs_cat_put
238	messages on umount should be a thing of the past now.
239
240Sun Dec 14 01:12:58 1997  a sun  <asun@zoology.washington.edu>
241
242	* dir.c
243	changed mark_inodes_deleted to dget/d_delete/dput the dentry
244	instead of just dropping it. the bytes available should now
245	be updated properly upon deletion.
246
247Wed Dec 10 00:01:25 1997  a sun  <asun@zoology.washington.edu>
248
249	* dir.c
250	changed mark_inodes_deleted to drop the dentry instead of
251	just deleting it.
252
253	TODO: bytes available aren't being properly updated when a
254	resource fork gets deleted.
255
256Mon Dec  8 23:22:40 1997  a sun  <asun@zoology.washington.edu>
257
258	* dir_cap.c, dir_nat.c, dir_dbl.c, dir.c
259	* hfs.h, linux/hfs_sysdep.h, linux/hfs_fs_i.h
260	Added code to drop ({dbl,cap,nat}_drop_dentry) invalid
261	dentries when creating or moving a file.
262
263	* inode.c
264	Added code to delete cached dentries when a file gets deleted.
265
266	* current yuckiness: there's an extra hfs_cat_put somewhere. it's
267	harmless but bothersome.
268
269Thu Dec  4 00:14:03 1997  a sun  <asun@zoology.washington.edu>
270
271	* dir.c, dir_cap.c, dir_nat.c, file.c, file_hdr.c, inode.c,
272	* linux/{hfs_sysdep.h, hfs_fs.h}, version.c:
273	Completed first code dentrification sweep. It mounts! It copies!
274	It dcaches!
275

287
288	* HFS.sgml:
289	Add some URLs and remove the (now empty) FAQ section.

337
338	* bnode.c:
339	Check the record table in each bnode as we read it from disk.
340
341	* super.c, mdb.c, hfs.h:
342	Deal with the ATTRIB_CLEAN bit of the MDB properly (in mdb.c).
343
344	* super.c, hfs.h, mdb.c:
345	Search for the alt-MDB rather than using the device size to find it.
346
347Wed Apr  9 03:39:05 1997  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
348

359
360Sat Apr  5 10:44:42 1997  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

419	Rearrange headers in preparation for inclusion in the kernel.
420
421	* hfs_fs_sb.h, hfs_fs.h:
422	Add forward declarations so other code can include these headers.
423
424	* hfs_sysdep.h:
425	Include __constant_hton[ls]() for little-endian machines.
426
427	* hfs_fs.h, hfs_sysdep.h, hfs.h:

436	Big type system changes in preparation for kernel inclusion:
437	'[US](8|16|32)' -> 'hfs_[us](8|16|32)' (avoids name space pollution)
438	'hfs_name_t' -> 'struct hfs_name' (allows forward declaration)
439
440	* super.c, hfs_fs.h:
441	Add init_hfs_fs() to super.c for non-module compilation.

946
947	* bins_del.c:
948	hfs_bnode_update_key() was still corrupting the header node sometimes.
949
950	* catalog.c, dir.c:
951	Fix problem with extending the catalog B-tree hanging hfs_cat_commit().
952	Fix a race that could delete a non-empty directory.

961
962	* hfs_fs.h, dir_cap.c, dir_dbl.c, dir_nat.c:
963	Mangle the names as first step in hfs_{cap,dbl,nat}_lookup().
964	Use the new hfs_streq() to catch mixed case matches to the special
965	files and directories in hfs_{cap,dbl,nat}_lookup().
966	Store reserved names only once.
967
968	* dir.c, hfs.h, string.c:
969	Implement hfs_streq() which tests for string equality more
970	rapidly than hfs_strcmp() by checking for equal length first,
971	and use it when checking for reserved names.
972
973	* inode.c, TODO, dir_cap.c, dir_dbl.c, README.sgml:
974	Provide the metadata for the root directory for the CAP and AppleDouble
975	schemes in the files ".:rootinfo:" and "%RootInfo", respectively.
976
977	* TODO, super.c:
978	Add (untested) support for the old Mac Plus style of partition map.
979
980	* bdelete.c, TODO:
981	Note the possibility of bdelete() to hanging on a corrupted B-tree.
982
983	* TODO:
984	Add items corresponding to some of the 'XXX' comments in the sources.
985
986	* dir_dbl.c, dir_cap.c:
987	Update comments, removing ref. to a comment that once existed in inode.c
988
989	* catalog.c:
990	Remove some redundant locking and error checks

1006	where it can be done an entire node at a time.
1007
1008Fri Aug 16 05:02:59 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1009
1010	* TODO:
1011	Add AppleShare support to the list of goals.
1012
1013	* trans.c, super.c, hfs_fs.h, README.sgml:
1014	Add a "names=netatalk" mount option, since
1015	Netatalk quotes initial periods and CAP doesn't.
1016
1017	* Makefile:
1018	Oops! Had removed the 'include .depend' from Makefile.
1019
1020	* inode.c, hfs_fs.h, file_nat.c, file_dbl.c, file.c, dir_nat.c,
1021	  dir_dbl.c, dir_cap.c, dir.c, README.sgml:
1022	Update for 2.0.1 and newer kernels.
1023
1024	* Makefile:
1025	Get rid of ifeq stuff and use a .tmpdepend file to make sure
1026	a failed 'make depend' doesn't allow a 'make hfs.o'.
1027
1028Wed Aug 14 01:03:01 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1029

1055	Add missing function comments.
1056
1057
1058	* extent.c:
1059	Insignificant code change removing an unneeded indirection.
1060
1061	* btree.c, hfs_btree.h, balloc.c, bnode.c:
1062	Add a 'sys_mdb' field to (struct hfs_btree).
1063
1064	* extent.c, hfs_sysdep.h, sysdep.c, bnode.c, balloc.c, bfind.c,
1065	  Makefile:
1066	Move hfs_buffer_read() from hfs_sysdep.h to sysdep.c so it can use
1067	the symbol HFS_SECTOR_SIZE rather than the manifest constant 512.
1068	Have hfs_buffer_read() print an error message,
1069	and remove redundant errors from the callers.
1070
1071	* hfs_sysdep.h, mdb.c, super.c, file.c, hfs.h, hfs_btree.h, catalog.c,
1072	  extent.c, btree.c, balloc.c, bfind.c, bnode.c:
1073	Get rid of the type hfs_device and the fields of that type,
1074	using the type hfs_sysmdb and the 'sys_mdb' field in its place.
1075
1076	* Makefile:
1077	Fix definition of HDRS variable.
1078
1079	* README.sgml, version.c:
1080	Bump version up to "pre-0.7-1".

1084	B-tree code, HFS code and Linux code.
1085
1086	* bitmap.c, bitops.c, hfs.h, hfs_sysdep.h, balloc.c:
1087	Implemented portable set of bit operations in hfs_sysdep.h
1088

1097	Remove call to hfs_mdb_dirty(), since the hfs_brec_relse() does it.
1098
1099	* hfs.h, extent.c, file.c:
1100	Move hfs_getblk() from extent.c to file.c, since that is now the
1101	only file that actually uses it.
1102
1103	* balloc.c:
1104	Replace use of hfs_getblk() in balloc.c with a local function
1105	(get_new_node()) that doesn't retry, since B-trees can't shrink.
1106
1107	* hfs.h, hfs_btree.h, hfs_sysdep.h, mdb.c, extent.c:
1108	Make hfs_buffer a typedef.

1114	* super.c, mdb.c, catalog.c:
1115	Rename hfs_cat_sync() to hfs_cat_commit() and call it
1116	from hfs_mdb_commit() rather than from hfs_write_super().
1117
1118	* catalog.c, file.c:
1119	Minimize the calls to hfs_mdb_dirty().   Now called when:
1120	1) A buffer holding a volume bitmap block is dirtied.
1121	2) A dirty B-tree node is written back to the buffers.
1122	3) A dirty catalog entry is written back to the buffers.
1123
1124	* hfs_sysdep.h, hfs.h:
1125	Make hfs_sysmdb a typedef.
1126
1127Sun Aug 11 08:46:10 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1128
1129	* hfs_sysdep.h, extent.c, hfs.h:

1138	Implemented hfs_dev_name() in hfs_sysdep.h
1139	as a portable call to produce a device name.
1140
1141	* super.c, hfs.h, mdb.c:
1142	Rename hfs_mdb_read() to hfs_mdb_get(), and don't take a
1143	'sys_mdb' argument.  That's the callers responsibility.
1144
1145	* sysdep.c, Makefile:
1146	Remove the pointless file sysdep.c
1147
1148	* README.sgml:
1149	Clean up the "System Requirements" section.
1150
1151Sat Aug 10 22:41:24 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

1157	  btree.c, binsert.c, bitmap.c, bitops.c, bfind.c, bins_del.c,
1158	  Makefile, balloc.c, bdelete.c:
1159	Includes the hfs.h that was missing from the previous check in.
1160	MAJOR include-file cleanup:
1161		hfs_btree.h merged into hfs.h
1162		hfs_btree_private.h renamed hfs_btree.h
1163		sysdep.h renamed hfs_sysdep.h
1164	Fixed some minor portability fixes shown up by the header split.
1165
1166	* README.sgml:
1167	Add instructions for a dealing with a missing linux/version.h
1168
1169	* hfs_fs.h, mdb.c, string.c, catalog.c, extent.c, btree.c, bitmap.c,
1170	  bitops.c, bnode.c, brec.c, bins_del.c, binsert.c, bdelete.c, bfind.c,
1171	  balloc.c:
1172	Major split of hfs_fs.h into Linux-specific
1173	part (hfs_fs.h) and HFS-specific part (hfs.h).
1174
1175	* file.c, extent.c:
1176	Move hfs_getblk() from file.c to extent.c
1177
1178	* sysdep.h, super.c, mdb.c, hfs_fs_sb.h, hfs_fs.h, file.c, extent.c,
1179	  catalog.c, bnode.c, bitmap.c:
1180	Make the field 's_mdb' in (struct hfs_sb_info) a pointer to
1181	the MDB, rather than the actual MDB.  This allowed the definition
1182	of (struct hfs_mdb) to be moved from hfs_fs_sb.h to hfs_fs.h.
1183
1184	* ccache.c, hfs_fs.h, Makefile, catalog.c:
1185	Merged ccache.c and catalog.c into the latter.
1186	Moved definition of (struct hfs_cat_rec) into catalog.c
1187
1188	* extent.c:
1189	Oops!  Last set of changes didn't compile but they're OK now.
1190
1191	* hfs_btree.h, hfs_fs.h, mdb.c, ccache.c, extent.c, btree.c:
1192	Move the definition of (struct hfs_raw_extent) inside
1193	extent.c and treat it as simple array of U16's elsewhere.
1194
1195	* hfs_fs.h, dir_dbl.c, dir_nat.c, ccache.c, catalog.c, dir_cap.c:
1196	Make hfs_cat_next() return the CNID and cdrType of the entry.
1197	Now catalog.c and ccache.c are the only files which
1198	depend on the structure of a catalog record on disk.
1199
1200	* dir.c, hfs_fs.h, catalog.c:
1201	Replace hfs_cat_new_{file,dir}() with hfs_cat_{create,mkdir}()
1202	which are wrappers for what used to be hfs_cat_create().
1203
1204	* hfs_fs.h, mdb.c, super.c, Makefile:

1214	Remove the unneeded 'hs' field from (struct hfs_mdb).
1215
1216	* TODO:
1217	Remove item about hfs_notify_change() needing to update metadata.
1218
1219	* inode.c, hfs_fs.h, hfs_fs_sb.h, file_cap.c, file_dbl.c, file_nat.c,
1220	  file.c, dir.c:
1221	Add a flags argument to hfs_{cap,dbl,nat}_buildmeta() so that
1222	it only builds the parts that are currently out-of-date.
1223	Call hfs_{cap,dbl,nat}_buildmeta() through hfs_update_meta()
1224	in hfs_notify_change() and hfs_rename() to update the metadata.
1225
1226	* dir.c:
1227	Make test for normal dir in update_dirs_{plus,minus}() more explicit.
1228
1229	* inode.c, file_cap.c, file_dbl.c, file_nat.c, dir_dbl.c, dir_nat.c,
1230	  file.c, README.sgml, dir_cap.c:
1231	Resolve the "meta-data" vs. "metadata" rivalry in favor of the latter.
1232

1234	Simplify some debugging code.
1235
1236	* hfs_btree_private.h, bnode.c, btree.c, balloc.c:
1237	Put the in-core copy of the header node IN the
1238	B-tree structure rather than just a pointer to it.
1239
1240	* hfs_btree_private.h, btree.c, bnode.c:
1241	Have hfs_btree_commit() call hfs_bnode_commit()
1242	to commit the header and root nodes.
1243
1244	* hfs_fs.h, super.c, hfs_btree_private.h, btree.c, hfs_btree.h,
1245	  balloc.c:
1246	Change hfs_commit_mdb() to hfs_mdb_commit().
1247	Make hfs_mdb_commit() call hfs_btree_commit().
1248	Move code to update B-tree size and extent
1249	from hfs_btree_extend() to hfs_btree_commit().
1250	Make hfs_btree_extend() call hfs_mdb_commit().
1251
1252	* super.c:
1253	Change hfs_commit_super() to hfs_commit_mdb().
1254
1255	* btree.c, bnode.c, bfind.c:
1256	Fixed up broken debugging code and error messages.
1257
1258	* super.c, hfs_btree_private.h, btree.c, hfs_btree.h, bdelete.c,

1263	Get rid of the add{16,32}() inlines as they are no longer used.
1264
1265	* hfs_btree_private.h, binsert.c, btree.c, bdelete.c, bfind.c, balloc.c:
1266	All the needed fields of the B-tree header are

1268
1269	* TODO:
1270	Remove "Implement write count" from TODO list.
1271
1272	* file.c, super.c, bnode.c:

1276	Fix directory entry counting in hfs_cat_move().
1277
1278	* balloc.c:
1279	Simplify hfs_btree_extend(), since the allocation
1280	request will get rounded up to the clumpsize.
1281
1282	* extent.c:
1283	Honor clumpsize when allocating blocks to files.
1284
1285	* file_cap.c, file_dbl.c, file_nat.c, super.c, dir.c, file.c,
1286	  ccache.c, catalog.c, balloc.c:
1287	Mark 44 functions in need of commenting.

1293	Now updates the backup MDB when a B-tree grows.
1294
1295	* extent.c:
1296	hfs_extent_free() had test against NULL backward.
1297	The result is that access to a file with extents in the extents
1298	B-tree would result in an infinite loop in hfs_cat_put().
1299
1300	* hfs_fs_sb.h, super.c, hfs_fs.h:
1301	Reorganize partition map code to get size of partition
1302	in preparation for dealing with the alternate MDB.

1311	Merge DOC, FAQ and README into README.sgml.
1312	Add make rules for building README.{txt,dvi}
1313
1314	* BUG_INFO, Makefile:
1315	Added a BUG_INFO script which attempts to collect some useful
1316	information which I'd like to see in every bug report I receive.
1317
1318	* Makefile, version.c:
1319	Added version.c which contains a version string.

1321Thu Aug  8 21:48:24 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1322
1323	* trans.c:
1324	Fix Latin-1 -> Macintosh filename mapping to change colons to pipes.
1325
1326	* trans.c:
1327	Fixed Mac->Latin-1 translation to behave as documented for the
1328	extended 8-bit characters without corresponding Latin-1 characters.
1329
1330	* inode.c, super.c, file.c, hfs_fs_i.h, hfs_fs_sb.h, DOC:
1331	Added a conv={binary,text,auto} mount option similar to that of the
1332	msdos, hpfs and iso9660 filesystems, but applying only to data forks.
1333	As compared to those filesystems, HFS has the advantage that only a
1334	single CR need be converted to a NL, rather than a CR/NL sequence, so
1335	it is quite safe to seek in the file.
1336	Additionally the 'Type' field is far more reliable indicator of text
1337	files than a file extension.
1338
1339	* super.c:
1340	Simplified parsing of mount options.
1341
1342	* super.c:
1343	Oops!  The part=<n> mount option was being parsed in octal!
1344
1345	* TODO:
1346	Remove "case=lower" from the list of goals.
1347
1348	* super.c, hfs_fs.h, hfs_fs_sb.h, string.c, dir_dbl.c, dir_nat.c,
1349	  dir_cap.c, DOC:

1351
1352	* dir.c:
1353	Simpler test for "normal" directory in update_dirs_{plus,minus}().
1354
1355	* hfs_fs_sb.h, super.c, dir.c, hfs_fs.h, catalog.c, DOC:
1356	Add mount options to specify what Type and Creator will be used for
1357	new files and change the default from NULLs to "????".

1366	Update for pre-0.7 version.
1367
1368	* hfs_fs.h:
1369	Create versioned module if CONFIG_MODVERSIONS is set in linux/config.h
1370
1371	* TODO:
1372	Note need for special steps for unaligned accesses on some machines.
1373
1374	* FAQ:
1375	Added Q0: What is HFS?
1376	Added Q7: Does hfs_fs work w/ 400k and 800k diskettes?
1377	Brought Q6 (about writability) up to date.
1378	Made a few other answers more verbose.
1379
1380Tue Aug  6 00:58:46 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1381
1382	* Makefile:
1383	Changed 'snapshot' rule to include cvs tag command.
1384
1385	* hfs_fs.h, dir_cap.c, dir_dbl.c, dir_nat.c, catalog.c, ccache.c:
1386	Implemented readers half of dir locking scheme so readdir() should
1387	produce consistent results and count_dir_entries() is not race prone.
1388
1389	* catalog.c:
1390	hfs_cat_move() was calling hfs_cat_decache() after changing
1391	the key rather than before, corrupting the hash lists.
1392
1393Mon Aug  5 14:03:46 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1394
1395	* hfs_fs.h, catalog.c:
1396	Implemented the writers half of a locking scheme for directories.
1397
1398	* inode.c:
1399	Fixed a serious bug in hfs_notify_change() that would allow a chmod()
1400	on directory meta-data and would cause the directory inode (if it was
1401	in memory at the time) to change into a file inode.
1402
1403	* inode.c:
1404	Fixed a problem with write permissions on directory meta-data.
1405
1406	* dir_dbl.c, dir_nat.c, dir_cap.c:
1407	hfs_{cap,dbl,nat}_readdir() now return the correct value in the 'd_ino'
1408	field of the dirent for all cases, something I think has always been
1409	done incorrectly until now.
1410
1411	* dir_nat.c, inode.c, dir_cap.c:
1412	In hfs_{cap,nat}_lookup() take advantage of the
1413	'file_type' field of (struct hfs_inode_info).
1414
1415	* TODO:
1416	Removed two accomplished goals (rename() and improved readdir()).
1417
1418	* inode.c, dir_dbl.c, dir_nat.c, hfs_fs_i.h, dir.c, dir_cap.c:
1419	Rewrite hfs_{cap,dbl,nat}_readdir() to take advantage of hfs_cat_next().
1420	They now use a uniform 'i_size' for all inodes for a given directory.
1421	This simplifies update_dirs_{plus,minus}() and eliminates the need for
1422	the 'file_size' and 'dir_link' fields of (struct hfs_inode_info).
1423	For the CAP and Netatalk schemes the meta-data directories are now the
1424	last entries rather than coming just after '.' and '..'.  This is in
1425	preparation for the day when we can write to the files in those
1426	directories, and ensures that when using 'tar' to copy HFS filesystems
1427	the file or directory will be created before the meta-data is written.
1428	Otherwise we could be stuck writing meta-data and not knowing if it is
1429	for a file or a directory!
1430
1431	* ccache.c:
1432	Updated count_dir_entries() for new hfs_cat_next().
1433
1434	* hfs_fs.h, catalog.c:
1435	hfs_cat{nth,next}() no longer take a 'types' argument,
1436	so they now return all entries.
1437	hfs_cat_next() now uses the ParID of the key to detect
1438	the end of the directory.
1439	hfs_cat_nth() now accepts n=0 as a valid input, requesting the thread.
1440
1441	* trans.c, string.c, super.c, dir_nat.c, hfs_fs.h, dir.c, dir_cap.c,
1442	  dir_dbl.c, catalog.c:
1443	Rename (struct hfs_cname) to the more appropriate (struct hfs_pstr).
1444
1445	* hfs_fs.h, hfs_btree.h:
1446	Move some constants from hfs_fs.h to hfs_btree.h
1447
1448	* bdelete.c, hfs_btree.h:
1449	Remove hfs_bdelete_brec() from public B-tree interface.
1450
1451	* hfs_btree_private.h, hfs_fs.h, btree.c, hfs_btree.h, bnode.c, brec.c,
1452	  bfind.c, bins_del.c, binsert.c, balloc.c, bdelete.c, Makefile:
1453	Split B-tree stuff into public and private parts:
1454		brec.c split into bfind.c and brec.c
1455		hfs_btree.h split into hfs_btree.h and hfs_btree_private.c
1456
1457	* inode.c:
1458	The tests and sets of the HFS_FIL_LOCK bit where all reversed!
1459
1460	* hfs_fs.h, ccache.c:
1461	Redo some ccache stuff, removing the 'error' field from
1462	(struct hfs_cat_entry) and ensuring that hfs_cat_put()
1463	will not sleep on an uninitialized entry.
1464
1465Sun Aug  4 23:43:28 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1466
1467	* sysdep.h:
1468	Change swap{16,32}() back to macros since hton[ls]() are functions.
1469
1470	* hfs_fs.h, ccache.c:
1471	Use only lowest order byte of parent CNID in hashing a catalog key.
1472
1473	* bdelete.c:
1474	The "improved" bdelete() was TOO paranoid looking for missing parents.
1475
1476	* ccache.c:
1477	Get rid of pointless swap16const(0).
1478
1479	* hfs_fs.h, inode.c, extent.c, ccache.c, dir_cap.c, dir_nat.c,
1480	  binsert.c, catalog.c:
1481	Store cnid and associated constants in big-endian byte order.
1482	This reduces the number of byte-order swaps required.
1483
1484	* sysdep.h:
1485	Make swap32() and swap16() inline functions.
1486
1487	* dir_nat.c, dir_cap.c, dir_dbl.c:
1488	Added hfs_rename() to the inode_operations for normal directories.
1489
1490	* dir.c, hfs_fs.h:
1491	Added hfs_rename() and cleaned up hfs_{create,mkdir,unlink,rmdir}().
1492
1493	* catalog.c:
1494	Added the missing check for moving a directory into itself.
1495
1496	* catalog.c, ccache.c, hfs_fs.h:
1497	Implement a nearly ideal hfs_cat_move().
1498	It still needs to prevent moving a directory into itself.
1499	The functions hfs_cat_{create,delete,move}() still need work with
1500	respect to their atomicity (especially vs. readdir).
1501
1502	* bdelete.c:
1503	Fixed a serious bug in hfs_bdelete_brec() that would yield a corrupted
1504	b-tree when the first record in a bnode was deleted.
1505	Made bdelete() more aggressive when checking for missing parents.
1506
1507Sat Aug  3 06:11:50 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1508
1509	* btree.c, super.c:
1510	Fixed a problem that caused a kernel oops when no HFS filesystem
1511	is found.
1512
1513Wed Jul 24 13:06:12 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1514
1515	* catalog.c:
1516	Remove race in hfs_cat_create() that could overflow directory valence.
1517
1518	* catalog.c:
1519	Fix hfs_cat_create() so the parent directory doesn't get deleted
1520	out from under it.  Otherwise we could have created files and
1521	directories in deleted directories.
1522
1523	* hfs_fs.h, dir_cap.c, dir_dbl.c, dir_nat.c, catalog.c, ccache.c:
1524	Redo hfs_cat_{next,nth}() in terms of which entry types to
1525	allow, rather than which to skip.
1526
1527	* catalog.c:
1528	The function hfs_cat_create() would fail to hfs_cat_put(entry) if
1529	the 'record' argument was invalid or if the 'result' argument was NULL.
1530
1531	* dir.c:
1532	The functions hfs_{create,mkdir,unlink,rmdir} all failed to
1533	call iput() when their arguments conflicted with a reserved name.
1534
1535	* catalog.c, hfs_fs_sb.h:
1536	Start over on rename().  Still unfinished.
1537	Fix silly bug in hfs_cat_create() that made it always fail.
1538
1539	* ccache.c:
1540	Fix byte-order bug in write_entry().
1541
1542Tue Jul 23 12:12:58 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1543
1544	* dir_dbl.c, dir_nat.c, hfs_fs.h, dir.c, dir_cap.c:
1545	Remove the macros KEY() and PARENT() since the key is now easy
1546	to access through the catalog entry.
1547	Replace the macros NAME{IN,OUT}() with inline functions
1548	hfs_name{in,out}() to gain type checking of arguments.
1549
1550	* catalog.c:
1551	Remove the macro TYPE().
1552
1553	* inode.c, file_dbl.c, file_nat.c, file.c, file_cap.c:
1554	Remove the #define's of the unused macro KEY().
1555
1556	* hfs_fs.h, dir_cap.c, dir_dbl.c, dir_nat.c, catalog.c, dir.c:
1557	Replace hfs_lookup_parent() in dir.c with hfs_cat_parent() in catalog.c.
1558	This new function performs locking to protect against rename() changing
1559		the parent during I/O.
1560	It is also intended for use with files as well as directories.
1561	Change hfs_{cap,dbl,nat}_lookup() to use the new function.
1562
1563	* dir.c, hfs_fs.h, catalog.c:
1564	Remerge hfs_cat_{create,mkdir}() into hfs_cat_create() and resurrect
1565		hfs_cat_new_{file,dir}().
1566	Fix hfs_cat_{create,delete} to use the improved catalog cache for
1567		locking in place of directory-level create/delete locks.
1568	Fix hfs_{create,mkdir}() to use the new hfs_cat_create().
1569
1570	* hfs_fs.h, ccache.c:
1571	Rewrite parts to remove need for specialized create/delete locking.
1572	Use new case-independent hash function.
1573	Fix bug in hfs_cat_get() that would read an entry w/o locking it.
1574	Call hfs_relinquish() before retrying a deleted entry in hfs_cat_get.
1575	If there is a read error, then don't retry in hfs_cat_get().
1576	Remove unused 'version' field from (struct hfs_cat_entry).
1577
1578	* sysdep.h:
1579	Add hfs_relinquish(), a system-independent alias for schedule().
1580
1581	* hfs_fs.h, string.c:
1582	Add hfs_strhash(), a simplistic case-independent hash function.
1583
1584	* hfs_fs.h, inode.c:
1585	Make hfs_iget() an inline function.
1586
1587	* TODO:
1588	Add a few goals and removed those that have been achieved.
1589
1590	* Makefile:
1591	Add ccache.c to list of source files.
1592	Add rule for *.s files and include them in the 'clean' rule.
1593
1594Wed Jul 17 17:22:45 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1595
1596	* sysdep.h, trans.c, string.c, super.c, hfs_fs_i.h, hfs_fs_sb.h,
1597	  inode.c, hfs_btree.h, hfs_fs.h, file_dbl.c, file_nat.c, extent.c,
1598	  file.c, file_cap.c, dir_dbl.c, dir_nat.c, ccache.c, dir.c,
1599	  dir_cap.c, btree.c, catalog.c, bnode.c, brec.c, balloc.c:
1600	Total rewrite of the inode-handling stuff to be centered around
1601	a catalog entry cache (ccache.c).  This results not only in a far
1602	more sensible way of doing things, but also removed many race
1603	conditions. (The source and object code both got smaller too!)
1604	Many small "undocumented features" were also fixed.
1605	Replace HFS_CNAME with (struct hfs_cname).
1606	rename() has been temporarily abandoned.
1607
1608Thu Jul 11 01:14:38 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1609
1610	* dir.c:
1611	As written hfs_lookup_parent() had two overlapping read requests
1612	in the catalog tree.  This could have led to deadlock.
1613
1614Wed Jul 10 09:27:00 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1615
1616	* catalog.c, hfs_fs.h, bdelete.c:
1617	More work on getting rename() fleshed out.  Still not done.
1618	Before I can finish it looks like I'll need to build a
1619	mechanism for exclusive access to the catalog tree.  There
1620	just doesn't seem to be any other way to get proper POSIX
1621	semantics without a bunch of race conditions elsewhere.
1622
1623	* hfs_fs.h, inode.c, dir_cap.c, dir_dbl.c, dir_nat.c, catalog.c:
1624	More work on the still incomplete rename() code.
1625	Merge hfs_cat_add_{dir,file}() into hfs_cat_create().
1626	Add file-thread support to hfs_cat_{create,delete,rename}.
1627
1628Tue Jul  9 09:43:15 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1629
1630	* inode.c, dir_dbl.c, dir_nat.c, extent.c, dir_cap.c:
1631	The indirect (struct hfs_file) was causing blocks not to be freed
1632	when files where deleted, and an omission in hfs_put_inode() was
1633	preventing the inode from getting freed.  Both are now fixed.
1634
1635	* hfs_fs.h, dir_dbl.c, dir_nat.c, hfs_btree.h, catalog.c, dir_cap.c,
1636	  bdelete.c:
1637	Made unlink() and rmdir() more race resistant and did some more
1638	work on the still incomplete code for rename().
1639
1640	* btree.c, bnode.c:
1641	There was a serious race condition in the bnode cache, so
1642	hfs_bnode_find() is now modeled after Linus's inode cache.
1643
1644Mon Jul  8 10:33:38 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1645
1646	* hfs_fs_i.h, inode.c, file_cap.c, file_dbl.c, file_nat.c, dir_dbl.c,
1647	  dir_nat.c, file.c, dir.c, dir_cap.c:
1648	More changes to layout of (struct hfs_inode_info).
1649
1650	* super.c, inode_cap.c, inode_dbl.c, inode_nat.c, inode.c, hfs_fs_i.h,
1651	  hfs_fs_sb.h, file_nat.c, hfs_fs.h, file.c, file_cap.c, file_dbl.c,
1652	  Makefile, catalog.c:
1653	Implemented new layout for (struct hfs_inode_info) resulting in the
1654	elimination of lots of duplicated code for hfs_*_write_inode(),
1655	hfs_*_put_inode() and *_open() functions.
1656	Merged inode_*.c files back into inode.c.
1657	Not fully tested.
1658
1659	* TODO:
1660	Add a few more of my goals to the list.
1661
1662	* README:
1663	Documentation updates.
1664
1665	* inode_nat.c, inode_cap.c, inode_dbl.c, inode.c, hfs_fs.h, hfs_fs_i.h,
1666	  file.c, file_cap.c, file_dbl.c, file_nat.c, catalog.c:
1667	(struct hfs_file) and metadata are read when file is opened or
1668	truncated and are released by iput().
1669
1670Sun Jul  7 23:55:43 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1671
1672	* inode_nat.c, inode_cap.c, inode_dbl.c, inode.c, dir_nat.c, hfs_fs.h,
1673	  hfs_fs_i.h, dir_cap.c, dir_dbl.c, catalog.c, dir.c:
1674	(struct hfs_dir) is now inside (struct hfs_inode_info) once again.
1675
1676	* inode_nat.c, super.c, inode_cap.c, inode_dbl.c, inode.c, file_nat.c,
1677	  hfs_btree.h, hfs_fs.h, extent.c, file_cap.c, file_dbl.c, dir_nat.c,

1679	  bins_del.c, binsert.c, bnode.c, bfind.c, balloc.c, bdelete.c,
1680	  Makefile:
1681	Remerged (struct hfs_bpath) and (struct hfs_brec), merging the
1682	files bfind.c and bpath.c as a resurrected brec.c.
1683
1684Sat Jul  6 21:47:05 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1685
1686	* inode_cap.c, inode_dbl.c, inode_nat.c, inode.c, hfs_fs.h, hfs_fs_i.h,
1687	  file_cap.c, file_dbl.c, file_nat.c, hfs_btree.h, dir_nat.c, extent.c,
1688	  dir.c, dir_cap.c, dir_dbl.c, btree.c, catalog.c, bfind.c, bpath.c,
1689	  binsert.c, bdelete.c:
1690	Renamed (struct hfs_brec_key) to (struct hfs_bkey).
1691
1692Tue May 28 07:53:24 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1693
1694	* inode_cap.c, catalog.c:
1695	Spelling fixes.
1696
1697	* inode_nat.c, super.c, inode_cap.c, inode_dbl.c, inode.c, hfs_fs.h,
1698	  hfs_fs_i.h, hfs_fs_sb.h, file.c, file_dbl.c, file_nat.c, dir_dbl.c,
1699	  dir_nat.c, extent.c, dir.c, dir_cap.c, catalog.c:
1700	Structures got too big, so I had to add a layer of indirection
1701	to (struct hfs_inode_info).
1702	This means we must clear_inode() in inode_put().
1703
1704Mon May 27 01:32:42 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1705
1706	* catalog.c, file_cap.c:
1707	Some sizeof() stuff now uses variable not type.
1708
1709	* hfs_fs.h:
1710	Make HFS_I() and HFS_SB() inline to gain type checking.
1711
1712Sun May 26 13:34:17 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1713
1714	* dir_nat.c:
1715	Oops.  Had left some debugging printk()s in place.
1716
1717	* file_dbl.c, file_nat.c, file_cap.c:
1718	Cleaned up variable names for consistency.
1719
1720	* hfs_fs_sb.h:
1721	Add a couple 'const's to function typedefs.
1722
1723	* hfs_fs.h:
1724	Add and update function prototypes.
1725	Cleaned up type names.
1726	Fix debugging malloc code.
1727	Add hfs_iget_by_name() as an inline function.
1728
1729	* sysdep.h:
1730	Remove extra semicolon from macro definitions.
1731
1732	* super.c:
1733	Use new hfs_iget_by_name() to get root inode.
1734
1735	* extent.c:
1736	Cleaned up some variable naming for consistency.
1737
1738	* catalog.c:
1739	Added (untested) code for hfs_cat_move_file().
1740
1741	* catalog.c:
1742	Fix one missed call to hfs_cat_build_key().
1743	Make hfs_cat_add_{file,dir}() take a cat_entry as an argument.
1744	Add hfs_cat_new_{file,dir}() to generate new cat_entry's.
1745
1746	* dir_dbl.c, dir_nat.c, dir.c, dir_cap.c:
1747	Cleaned up type and variable names.
1748	Updated calls to hfs_cat_build_key() and NAMEOUT()
1749	Use new hfs_iget_by_*() calls.
1750
1751	* inode_cap.c, inode_dbl.c, inode_nat.c:
1752	Cleaned up type and variable names.
1753
1754	* inode.c:
1755	Update calls to hfs_cat_build_key().
1756	Cleaned up type and variable names.
1757	Implemented a hierarchy of hfs_iget_by*() calls.
1758
1759	* catalog.c:
1760	Change hfs_cat_build_key() to take a HFS_CNAME as input.
1761
1762	* btree.c:
1763	Initialize lsize and psize fields of file.
1764
1765	* trans.c:
1766	Now passes type HFS_CNAME and has name/len in "normal" order.
1767
1768Tue May 21 07:02:34 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1769
1770	* bnode.c:
1771	Attempt to read invalid bnode would have led to an infinite loop under
1772	certain circumstances.  One way to cause this was with an invalid
1773	partition table which points beyond the end of the device.
1774
1775Sat May 11 12:38:42 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>

1801	  dir_cap.c, bpath.c, btree.c, binsert.c, bnode.c:
1802	"FID reform": 'fid' became 'cnid' (Catalog Node ID), and is now
1803	a field in (struct hfs_file).  The new name is more consistent
1804	with Apple's documentation.  The presence of 'cnid' in (struct
1805	hfs_file) help move more of the code toward OS-independence.

1814Sat Apr 27 12:28:54 1996  Paul H. Hargrove  <hargrove@sccm.stanford.edu>
1815
1816	* FAQ:
1817	Updated for current writability status.
1818

1839	Fixed a couple more type size assumptions.
1840
1841	* hfs_fs.h, balloc.c, bitmap.c, bitops.c:
1842	"Portable" bitmap handling was wrong for just about everything but
1843	the i386 and the "inverse big-endian" bit ordering that I thought
1844	the m68k port was using.  It seems the m68k port is now using standard
1845	big-endian bit-numbering conventions.
1846	This code is now correct for the standard big- and little-endian bit
1847	orderings. (which should cover all Linux systems?)
1848	Also no longer assumes sizeof(long) == 4, though that might still be
1849	a problem in other parts of the code.
1850

1880
1881	* bpath.c, bins_del.c:
1882	hfs_bdelete() is now working "correctly", but needs some cleaning up.

2013	  bins_del.c:
2014	Backed-out changes to hfs_binsert() that added the ability to

2173

2392
2393Mar 09, 1996: snapshot-09Mar96 hargrove@sccm.stanford.edu (Paul H. Hargrove)
2394	NOT AN OFFICIAL RELEASE
2395	Fixed up debugging code that was broken by split of btree.c
2396	Added debugging kmalloc/kfree
2397	Fixed memory leak in hfs_bnode_relse()
2398
2399Mar 08, 1996: snapshot-08Mar96 hargrove@sccm.stanford.edu (Paul H. Hargrove)
2400	NOT AN OFFICIAL RELEASE
2401	now reset blocksize on device when done.
2402	hfs_binsert done (except for the full tree case).
2403	btree.c split up into manageable pieces (need to sort out hfs_btree.h)
2404
2405Feb 26, 1996: snapshot-26Feb96 hargrove@sccm.stanford.edu (Paul H. Hargrove)
2406	NOT AN OFFICIAL RELEASE
2407	Some writability.
2408	Bug with multiple opens of meta data fixed.
2409	Netatalk support no longer considered experimental.
2410
2411Virtually everything has changed, so I've lost track here.
2412
2413Nov 16, 1995: snapshot-16Nov95 hargrove@sccm.stanford.edu (Paul H. Hargrove)
2414	NOT AN OFFICIAL RELEASE
2415	Still more comments.
2416	btree.c back to 80 columns.  will do same to other files soon.
2417	Starting with btree.c have begun to put file contents into some
2418		sort of standard order.
2419	Moved metadata reading to VFS open() routine and now free it in
2420		the VFS release() routine.  Much cleaner than the old way.
2421	Unified hfs_iget by shifting scheme-dependent code into a function
2422		pointer in the superblock.  This could/should be shifted to
2423		a VFS read_inode() routine if that can be done cleanly.
2424	Probably lots of other changes; I've lost track.
2425
2426Nov 05, 1995: version 0.5.3 hargrove@sccm.stanford.edu (Paul H. Hargrove)
2427	NOT AN OFFICIAL RELEASE
2428	1.2.x compatibility removed
2429	Added lots of comments to btree.c and cleanup some code.  The result
2430		is that the source file doubled in size while the object
2431		file dropped in size by 20%.
2432	Added some comments to super.c and dir.c as well.
2433	Cleaned up some stuff in dir.c adding some additional error checking
2434		and moving closer to using a unified hfs_iget by migrating
2435		common code into lookup_parent().
2436	Changed btree.c to use a separate bnode cache per filesystem.
2437	Renamed a bunch of the bnode functions in btree.c
2438
2439Jun 29, 1995: version 0.5.2 hargrove@sccm.stanford.edu (Paul H. Hargrove)

2441	Will compile under 1.2.x or 1.3.x by changing one line in Makefile.
2442	Started adding magic numbers to structures for "safety".
2443	Don't strip internal symbols when linking or loading, as this made
2444		good bug reports rather difficult.
2445	Fixed a bug that could cause the fs to lock-up after trying to open
2446		a non-existent file.
2447	Fixed a bug that allowed files to appear truncated, when in fact it
2448		is still not possible to truncate a file.
2449	Added more/better comments to header files.
2450	Deal with volume and b-tree bitmaps in preparation for writing.
2451	Fixed readdir() to deal properly with the case where the directory
2452		changes while writing to user-space. (which can't yet
2453		actually happen, until directories are writable).
2454
2455Jun 23, 1995: version 0.5.1 hargrove@sccm.stanford.edu (Paul H. Hargrove)
2456	BUG FIX RELEASE
2457	Removed two debugging messages that didn't belong.
2458	Fixed a typo that prevented modified inodes from being written to disk.
2459	Added a missing line which prevented rmmod'ing sometimes.
2460	Added a missing line which caused errors when modifying .finderinfo or
2461		.resource under the CAP system.
2462	Added a notify_change() to keep mode bits sensible, and to cause
2463		changes to an inode to affect the data fork and resource fork
2464		of a file together.
2465
2466Jun 22, 1995: version 0.5 hargrove@sccm.stanford.edu (Paul H. Hargrove)
2467	Fixed a bug that was giving wrong values for i_blocks
2468	Partly writable (can only 'touch' existing files, so far)
2469	Removed case= mount option.  It will be back eventually.
2470	Can now deal with CDROMs (and hard disks?), many thanks to
2471		Holger Schemel for this work.
2472	Latin-1 filename conversion also due to Holger Schemel.
2473	Rewritten btree operations.
2474
2475Feb 28, 1995: version 0.4 hargrove@sccm.stanford.edu (Paul H. Hargrove)

2477	Now using string comparison code donated by ARDI (see string.c)
2478	Code reorganized to use data structures more like ARDI's.
2479	More code reorganization to abstract the btree operations.
2480	Added the fork= mount option.

2492
2493Jan 12, 1995: version 0.2 hargrove@sccm.stanford.edu (Paul H. Hargrove)
2494	Should now work on all HFS volumes, but still only tested on floppies.
2495	Got smaller and faster with some code reorganization.
2496	Since Linus moved htons() and friends to an asm file, should now be
2497	 truly endian-independent, but still only tested on Intel machines.
2498	Requires Linux >= 1.1.77, since Linus moved htons().
2499
2500Jan 05, 1995: version 0.1 hargrove@sccm.stanford.edu (Paul H. Hargrove)
