the attribute list attribute. This is the same bug that was biting us in the
ntfs driver 2.1.4 and was fixed in 2.1.5. Windows XP creates files where an

Fix a silly bug in attrib.c::ntfs_external_attr_find() which caused
us to always return the same attribute during an enumeration as soon
as the end of the attributes to be enumerated was reached thus
causing the program doing the enumeration to hang in a tight loop.
NOTE: There is still work to do as ctx->al_entry is set to NULL
instead of to the position in the attribute list at which to insert.

- Check whether the attribute name needs moving when resizing the
resident part of an attribute record.
- Create internal function ntfs_attr_find_in_attrdef().
(Logical change 1.78)
- Rename ntfs_resident_attr_shrink() to ntfs_resident_attr_resize()
and make it resize upwards as well as downwards.
- Change ntfs_attr_truncate() to allow resizing upwards of resident
attributes.
(Logical change 1.75)

- Only deallocate clusters, truncate the runlist, and regenerate the

value is sufficiently large.
(Logical change 1.67)
free the extent inode attached to the search context but leave it
attached to the base inode, so this would lead to memory corruption
and worse problems. Thanks to Szakacsits Szabolcs for spotting this.
We now don't close extent inodes any more at all and just leave it
to the closing of the base inode to dispose of all the extent inodes.

mkntfs delayed. more reverse engineering required to determine exact method of

2001/06/01 02:07:25-00:00 !antona
It has been a long time since last commit. At moment have done a lot of work
on mkntfs but also at the moment ntfsfix and ntfsdump_logfile and libntfs are
broken. Basically only mkntfs works and that is not complete either.
2001/04/12 22:37:21-00:00 !antona
Add a description and structure for holding attributes in memory. No code to
use it yet but it's a start. The design is geared with the ideas of making
searching for attributes and using/implementing the search context as easy as
possible, integrating the attributes into their mft_entries and maintining a
fast sync volume path.
Comments welcome.

User space conversion of locking complete. I settled for using simple spinlocks
and atomic variables and instead of deadlocking/livelocking when using
spin_lock(), use spin_trylock() in a while letting go of the cpu between each
call and making a maximum of 100 iterations (or we return EDEADLK error code).
This is not the most efficient way, especially as can't have multiple readers
but it is the simplest way to go about things.
Should now have (almost) all required helper functions for dealing with mft
entries implemented.
Now need the file handling and then convert the whole project to use the new
code and then can finally get back to work on attribute searching...

Commit of current state of development including locking a la kernel.
This doesn't work on user space (semaphores don't work).
Just want to have it committed. Will take out locking / modify it where
necessary to use pthreads ASAP.
2001/04/02 02:04:37-00:00 !antona
Everything compiles again! Yey! (Don't know about working though, haven't tried
it... So be careful...)
The definitely final find_{first_}attr() functions are in place. Currently
still no support for attribute lists.
The two new _RE files contain the C-fied and more or less (more less than more
actually) cleaned up functions from the ntfs driver. Once they are cleaned
up (find_attr() is already completed but I left it in the _RE files for future
reference/educational value) and modified to suit my ideas of how they should
work, which are not quite the same as the driver way, they will make it into
attrib.[ch].
If anyone gives the new code a try, I would be interested in whether it worked
or not... (-;
