| (Note: I consider version numbers as cheap. That means | |
| that I do not like numbers like 0.1 and the like for | |
| things that can be used since quite some time. But | |
| then, 3.1 doesn't mean 'perfectly stable', too.) | |
| Known bugs: | |
| ----------- | |
| - Doesn't work on the alpha. The only 64/32-bit | |
| problem that I'm aware of (pointer/int conversion | |
| in readdir()) gives compiler warnings but is | |
| apparently not causing the failure, as directory | |
| reads basically work (but all files are of size 0). | |
| Alas, I've got no alpha to debug. :-( | |
| - The partition checker (drivers/block/genhd.c) | |
| doesn't work with devices which have 256 byte | |
| blocks (some very old SCSI drives). | |
| - The feature to automatically make the fs clean | |
| might leave a trashed file system with the | |
| bitmap flag set valid. | |
| - When a file is truncated to a size that is not | |
| a multiple of the blocksize, the rest of the | |
| last allocated block is not cleared. Well, | |
| this fs never claimed to be Posix conformant. | |

| Version 3.10 | |
| ------------ | |
| - Changed partition checker to allow devices | |
| with physical blocks != 512 bytes. | |
| - The partition checker now also ignores the | |
| word at 0xd0 that Windows likes to write to. | |
| Version 3.9 | |
| ----------- | |
| - Moved cleanup from release_file() to put_inode(). | |
| This makes the first one obsolete. | |
| - truncate() zeroes the unused remainder of a | |
| partially used last block when a file is truncated. | |
| It also marks the inode dirty now (which is not | |
| really necessary as notify_change() will do | |
| it anyway). | |
| - Added a few comments, fixed some typos (and | |
| introduced some new ones), made the debug messages | |
| more consistent. Changed a bad example in the | |
| doc file (affs.txt). | |
| - Sets the NOEXEC flag in read_super() for old file | |
| systems, since you can't run programs on them. | |
| Version 3.8 | |
| ----------- | |
| Bill Hawes kindly reviewed the affs and sent me the | |
| patches he did. They're marked (BH). Thanks, Bill! | |
| - Cleanup of error handling in read_super(). | |
| Didn't release all resources in case of an | |
| error. (BH) | |
| - put_inode() releases the ext cache only if it's | |
| no longer needed. (BH) | |
| - One set of dentry callbacks is enough. (BH) | |
| - Cleanup of error handling in namei.c. (BH) | |
| - Cleanup of error handling in file.c. (BH) | |
| - The original blocksize of the device is | |
| restored when the fs is unmounted. (BH) | |
| - getblock() did not invalidate the key cache | |
| when it allocated a new block. | |
| - Removed some unnecessary locks as Bill | |
| suggested. | |
| - Simplified match_name(), changed all hashing | |
| and case insensitive name comparisons to use | |
| uppercase. This makes the tolower() routines | |
| obsolete. | |
| - Added mount option 'mufs' to force muFS | |
| uid/gid interpretation. | |
| - File mode changes were not updated on disk. | |
| This was fixed before, but somehow got lost. | |
| Version 3.7 | |
| ----------- | |
| - Added dentry callbacks to allow the dcache to | |
| operate case insensitive and length ignorant | |
| like the affs itself. | |
| - getblock() didn't update the lastblock field in the | |
| inode if the fs was not an OFS. This bug only shows | |
| up if a file was enlarged via truncate() and there | |
| was not enough space. | |
| - Remove some more superfluous code left over from | |
| the old link days ... | |
| - Fixed some oversights which were in patch 2.1.78. | |
| - Fixed a few typos. | |
| Version 3.6 | |
| ----------- | |
| - dentry changes. (Thanks to Jes Sorensen for his help.) | |
| - Fixed bug in balloc(): Superblock was not set dirty after | |
| the bitmap was changed, so the bitmap wasn't sync'd. | |
| - Fixed nasty bug in find_new_zone(): If the current | |
| zone number was zero, the loop didn't terminate, | |
| causing a solid lock-up. | |
| - Removed support for old-style directory reads. | |
| - Fixed bug in add_entry(): When doing a sorted insert, | |
| the pointer to the next entry in the hash chain wasn't | |
| correctly byte-swapped. Since most of the users of the | |
| affs use it on a 68k, they didn't notice. But why did | |
| I not find this during my tests? | |
| - Fixed some oversights (version wasn't updated on some | |
| directory changes). | |
| - Handling of hard links rewritten. To the VFS | |
| they appear now as normal Unix links. They are | |
| now resolved only once in lookup(). The backside | |
| is that unlink(), rename() and rmdir() have to | |
| be smart about them, but the result is worth the | |
| effort. This also led to some code cleanup. | |
| - Changed name type to unsigned char; the test for | |
| invalid filenames didn't work correctly. | |
| (Thanks to Michael Krause for pointing at this.) | |
| - Changed mapping of executable flag. | |
| - Changed all network byte-order macros to the | |
| recommended ones. | |
| - Added a remount function, so attempts to remount | |
| a dircache filesystem or one with errors read/write | |
| can be trapped. Previously, ro remounts didn't | |
| flush the super block, and rw remounts didn't | |
| create allocation zones ... | |
| - Call shrink_dcache_parent() in rmdir(). | |
| (Thanks to Bill Hawes.) | |
| - Permission checks in unlink(). | |
| - Allow mounting of volumes with superfluous | |
| bitmap pointers read only, also allows them | |
| to be remounted read/write. | |
| - Owner/Group defaults now to the fs user (i.e. | |
| the one that mounted it) instead of root. This | |
| obsoletes the mount options uid and gid. | |
| - Argument to volume option could overflow the | |
| name buffer. It is now silently truncated to | |
| 30 characters. (Damn it! This kind of bug | |
| is too embarrassing.) | |
| - Split inode.c into 2 files, the superblock | |
| routines desperately wanted their own file. | |
| - truncate() didn't allocate an extension block | |
| cache. If a file was extended by means of | |
| truncate(), this led to an Oops. | |
| - fsuser is now checked last. | |
| - rename() will not ignore changes in filename | |
| casing any more (though mv(1) still won't allow | |
| you to do "mv oldname OldName"). | |
| Version 3.5 | |
| ----------- | |
| - Extension block caches are now allocated on | |
| demand instead of when a file is opened, as | |
| files can be read and written without opening | |
| them (e. g. the loopback device does this). | |
| - Removed an unused function. | |
| Version 3.4 | |
| ----------- | |
| - Hash chains are now sorted by block numbers. | |
| (Thanks to Kars de Jong for finding this.) | |
| - Removed all unnecessary external symbols. | |
| Version 3.3 | |
| ----------- | |
| - Tried to make all types 'correct' and consistent. | |
| - Errors and warnings are now reported via a | |
| function. They are all prefixed by a severity | |
| and have the same appearance: | |
| "AFFS: <function>: <error message>" | |
| (There's one exception to this, as in that function | |
| is no pointer to the super block available.) | |
| - The filesystem is remounted read-only after an | |
| error. | |
| - The names of newly created filesystem objects are | |
| now checked for validity. | |
| - Minor cleanups in comments. | |
| - Added this Changes file. At last! | |
| Version 3.2 | |
| ----------- | |
| - Extension block cache: Reading/writing of huge files | |
| (several MB) is much faster (of course the added | |
| overhead slows down opening, but this is hardly | |
| noticeable). | |
| - The same get_block()-routine can now be used for | |
| both OFS and FFS. | |
| - The super block is now searched in the block that | |
| was calculated and in the one following. This | |
| should remedy the round-off error introduced by | |
| the 1-k blocks that Linux uses. | |
| - Minor changes to adhere to the new VFS interface. | |
| - The number of used blocks is now also calculated | |
| if the filesystem is mounted read-only. | |
| - Prefixed some constants with AFFS_ to avoid name | |
| clashes. | |
| - Removed 'EXPERIMENTAL' status. | |
| Version 3.1 | |
| ----------- | |
| - Fixed a nasty bug which didn't allow read-only | |
| mounts. | |
| - Allow dir-cache filesystems to be mounted | |
| read only. | |
| - OFS support. | |
| - Several other changes I just cannot remember | |
| any more. | |
| Version 3.0 | |
| ----------- | |
| - Almost complete rewrite for the new VFS | |
| interface in Linux 1.3. | |
| - Write support. | |
| - Support for hard and symbolic links. | |
| - Lots of things I remember even less ... | |
| Version 2.0 | |
| ----------- | |
| - Fixed a few things to get it compiled. | |
| - Automatic root block calculation. | |
| - Partition checker for genhd.c | |
| ======================================== | |
| Let's just call Ray Burr's original affs | |
| 'Version 1.0'. |
