changelog

ARM 嵌入式 系统 设计与实例开发 实验教材 二源码

2000-01-02  a sun  <[e-mail]>

	* file.c (hfs_get_block): added hfs_get_block for regular files. 

1999-04-12  a sun  <[e-mail]>

	* file_hdr.c (hdr_read): added rootinfo behaviour for DID header.

1999-04-11  a sun  <[e-mail]>

	* super.c (parse_options): added s_version so that we can select
	between different versions of the same layout.

1999-04-05  a sun  <[e-mail]>

	* linux/hfs_fs.h: unified netatalk and appledouble header format. 
	added in all of the AFP attribute bits.

	* file_hdr.c: added netatalk appledouble v2 compatible headers. 

1999-01-30  a sun  <[e-mail]>

	* catalog.c (hfs_cat_move): fixed corruption problem with
	renames.

1999-01-27  a sun  <[e-mail]>

	* file_hdr.c (get/set_dates): got rid of broken afpd times. NOTE:
	you must use netatalk-1.4b2+asun2.1.2 or newer for this.

1998-12-20  a sun  <[e-mail]>

	* bdelete.c (del_root): assign bthLNode and bthFNode only if the
	root node becomes a leaf node. Disk First Aid no longer
	complains. Norton Utilities, of course, has decided that it
	doesn't like the root node number. bleah. i think that it might be
	due to Norton Utilities not expecting the root node to have moved.

1998-12-16  a sun  <[e-mail]>

	* sysdep.c (hfs_revalidate_dentry): fix inode dates when there's a
	timezone change.

1998-12-15  root  <[e-mail]>

	* extent.c (new_extent): expand block size variables to handle
	u32. 

	* mdb.c (hfs_mdb_get): AlBlkSiz shouldn't be capped at 65535. we
	should be able to handle much larger volumes now.

1998-11-21  a sun  <[e-mail]>

	* hfs_sysdep.h, hfs_fs.h: added hfs_from_utc/to_utc to deal with
	date differences on hfs formatted media. 

	NOTE: hfs extended keeps everything in utc, so we'll need to deal
	with that when appropriate.

1998-11-12  a sun  <[e-mail]>

	* extent.c (shrink_fork): added some lock_bitmap/unlock_bitmap's
	to protect hfs_clear_vbm_bits. we should no longer have problems
	with free_ablocks wrapping around.

1998-11-02  a sun  <[e-mail]>

	* mdb.c (hfs_mdb_get): plugged up an mdb failed initialization
	leak.

1998-10-31  a sun  <[e-mail]>

	* version.c (hfs_version): bumped to version 0.96.

	* mdb.c (hfs_mdb_commit): you only write out the alternate MDB
	when the catalog or extents overflow files grow. that just leaves
	the btree corruption problems. bleah (whilst deleting a bunch of
	files, more of the btree can get pruned away than desired).

1998-10-30  a sun  <[e-mail]>

	* dir.c: fixed a bunch of silliness with deletions. make sure to
	zero out stuff and set mark_inode_dirty().
	
1998-10-29  a sun  <[e-mail]>

	* string.c (hfs_strcmp, hfs_streq, hfs_strhash): converted them to
	take name/len arguments instead of hfs_name to reduce copying.

	* dir.c, dir_nat.c, dir_cap.c, dir_dbl.c, sysdep.c: modified
	relevant areas to reflect string.c changes.
	
1998-10-28  a sun  <[e-mail]>

	* hfs.h (hfs_lookup_dentry): oh my. more silliness. make sure to
	have the d_lookup use the same hash value as the one generated by
	hfs_hash_dentry. i also changed the argument order.
	(hfs_drop_special): change the argument order to be more in line
	with what the dcache stuff looks like.

	* sysdep.c (hfs_compare_dentry): the compare was returning the
	wrong value for correct matches and causing all sorts of
	mischief. this fixes both directory counts and mounting on top of
	hfs volumes.

	* file.c, file_cap.c, file_hdr.c: added mark_inode_dirty()'s in
	the relevant places.

1998-10-11  root  <[e-mail]>

	* mdb.c (hfs_mdb_get): moved initialization of mdb->entry_dirty
	list to here to deal with trying to read a bad hfs volume.

1998-10-10  a sun  <[e-mail]>

	* inode.c, catalog.c, dir_*.c, sysdep.c: parts of the dcache
	conversion didn't get done properly. specifically, i forgot to
	move the hfs_cat_puts into the right place. that's fixed now.

1998-09-11  a sun  <[e-mail]>

	* mdb.c: altered mdb struct to reflect hfs plus usage.

1998-08-27  a sun  <[e-mail]>

	* file.c, file_hdr.c, file_cap.c: dealt with the remaining
	copy_to/from_user() error cases.

1998-08-26  a sun  <[e-mail]>

	* super.c (hfs_read_super): fixed to deal with cdroms. why doesn't
	the cdrom layer call the partition table code?

Wed Jan 21 14:04:26 1998  a sun  <[e-mail]>

	* inode.c, sysdep.c
	use d_iput to uncache dentry from catalog entry instead of relying
	on put_inode. no more NULL pointer dereferences!

	* catalog.c
	cleaned up hfs_cat_put a little.
	
	ISSUES (non-fatal): mv dir dir2 while creating files in dir screws
	                    up directory counts.
		
			    deletion using netatalk screws up directory
 			    counts.

Thu Jan 15 19:14:28 1998  a sun  <[e-mail]>

	* catalog.c
	make deletion happen when requested instead of waiting until
	an hfs_cat_put as the dcache can hold onto entries for quite
	some time.

Wed Jan 14 14:43:16 1998  a sun  <[e-mail]>
	
	* catalog.c
	the current catalog allocation scheme allocates
	PAGE_SIZE/sizeof(struct hfs_cat_entry) entries at a time and keeps
	a pool of free entries up to this allocation unit * 8.

	* inode.c
	make sure to always hfs_cat_put if hfs_iget is going to return
	NULL.

	* string.c, catalog.c
	use linux' hashing method to generate hashes. the old hashing was
 	getting collisions. catalog.c also has a larger hash table to
 	prevent collisions.
	
Tue Jan 13 13:06:01 1998  a sun  <[e-mail]>

	* version.c
	bumped to 0.95+asun3

	* catalog.c
	re-wrote to dynamically allocate/delete catalog entries. on a 486,
	entries fit into the size-256 slab.

Wed Jan  7 19:33:33 1998  a sun  <[e-mail]>

	* inode.c 
	don't hfs_cat_put gratuitously in hfs_iget. that's a bad
 	idea and results in screwed up entry counts.

Tue Jan  6 14:38:24 1998  a sun  <[e-mail]>

	* version.c
	changed it to 0.95+asun2

	* sysdep.c
	altered catalog entry pruning to make sure that an iput
	gets done. for some reason, shrink_dcache_parent wasn't
	doing it.

	* catalog.c
	added a global dirty list to check for pruning.
	
Tue Jan  6 12:29:52 1998  a sun  <[e-mail]>

	* catalog.c
	re-wrote it to be similar to 2.1.x inode.c. this should
 	at least make catalog.c SMP safe. 

	* hfs.h, linux/hfs_fs.h
	moved dentry operations into hfs.h. these probably should
	be moved somewhere else.

	* super.c, dir_cap.c, dir_nat.c, dir_dbl.c, sysdep.c
	added dentry ops to hash everything to lowercase.

Sun Dec 28 22:48:53 1997  a sun  <[e-mail]>

	* sysdep.c, catalog.c, hfs.h
	as a temporary workaround until catalog.c gets re-written, 
	i flush the dcache if we need more entries. 
	
Fri Dec 19 15:11:21 1997  a sun  <[e-mail]>

	* dir_dbl.c
	statically allocate tmp_name instead of doing it dynamically.

	NOTE: well, those pesky hfs_cat_put messages still aren't gone. in
	addition, catalog.c needs to be modified to free up some entries
	when the cache gets filled up. 

Sun Dec 14 11:51:11 1997  a sun  <[e-mail]>

	* linux/hfs_fs.h
	moved the dentry stuff into within the #ifdef __KERNEL__ 
	part of hfs_fs.h and cleaned up a little.

Sun Dec 14 11:24:54 1997  a sun  <[e-mail]>

	* dir.c
	changed hfs_rename to delete all old dentries. hfs_cat_put
	messages on umount should be a thing of the past now.

Sun Dec 14 01:12:58 1997  a sun  <[e-mail]>

	* dir.c
	changed mark_inodes_deleted to dget/d_delete/dput the dentry
	instead of just dropping it. the bytes available should now
	be updated properly upon deletion.

Wed Dec 10 00:01:25 1997  a sun  <[e-mail]>

	* dir.c
	changed mark_inodes_deleted to drop the dentry instead of 
	just deleting it. 

	TODO: bytes available aren't being properly updated when a
	resource fork gets deleted.

Mon Dec  8 23:22:40 1997  a sun  <[e-mail]>

	* dir_cap.c, dir_nat.c, dir_dbl.c, dir.c
	* hfs.h, linux/hfs_sysdep.h, linux/hfs_fs_i.h
	Added code to drop ({dbl,cap,nat}_drop_dentry) invalid
	dentries when creating or moving a file.

	* inode.c
	Added code to delete cached dentries when a file gets deleted.

	* current yuckiness: there's an extra hfs_cat_put somewhere. it's
	harmless but bothersome.
	
Thu Dec  4 00:14:03 1997  a sun  <[e-mail]>

	* dir.c, dir_cap.c, dir_nat.c, file.c, file_hdr.c, inode.c,
	* linux/{hfs_sysdep.h, hfs_fs.h}, version.c:
	Completed first code dentrification sweep. It mounts! It copies!
	It dcaches!

	* super.c, mdb.c, hfs.h:
	Deal with the ATTRIB_CLEAN bit of the MDB properly (in mdb.c).

	* super.c, hfs.h, mdb.c:
