hfsutils - tools for reading and writing Macintosh HFS volumes
Copyright (C) 1996-1998 Robert Leslie
$Id: BLURB,v 1.1 1998/04/11 08:26:52 rob Exp $
===============================================================================
What is this?
HFS is the "Hierarchical File System" used on modern Macintosh computers.
With this package, you can read and write Macintosh-formatted media such as
floppy disks, CD-ROMs, and SCSI hard disks on most UNIX platforms. You can
also format raw media into an HFS volume.
This package contains a number of different tools:
* Several command-line programs (hmount, hls, hcopy, et al.)
* A Tk-based front-end for browsing and copying files through a
variety of transfer modes (MacBinary, BinHex, text, etc.)
* A Tcl package and interface for scriptable access to volumes
* A C library for low-level access to volumes
How is this different from other HFS packages?
This package attempts to provide a portable, free implementation of
routines for accessing HFS volumes. It is implemented as a set of user-level
tools to provide maximum portability.
The command-line programs are intended to be used in the same vein as the
Mtools command-line programs used to access MS-DOS filesystems.
The graphical front-end provides point-and-click access to Macintosh
volumes, which is often more convenient than the command line.
The Tcl interface offers a scriptable HFS "shell" that is more efficient
than the external command-line programs and allows for greater
extensibility.
The C library can be linked with other programs wanting to manipulate
Macintosh files in their native format. For example, an implementation of
the Macintosh Resource Manager could be built on top of this library to
provide seamless access to data objects contained within the resource forks
of Macintosh files.

hfsutils - tools for reading and writing Macintosh HFS volumes
Copyright (C) 1996-1998 Robert Leslie
$Id: CHANGES,v 1.14 1998/11/02 22:08:20 rob Exp $
===============================================================================
Version 3.2.6
* Added casts and made other changes to satisfy fussy signed/unsigned
compilers.
* Fixed a problem in which volumes were not marked as "cleanly unmounted,"
causing unnecessary scavenging to occur when the volume is mounted again.
* Fixed a problem where scavenging failed to mark all extents from the final
B*-tree node.
* Added a simple next-CNID verification to scavenging.
* Introduced a flags parameter to hfs_format(); new HFS_OPT_2048 format
option ensures 2048-byte physical-block file boundaries, compatible with
hybrid ISO 9660 schemes.
* New HFS_OPT_NOCACHE mount option inhibits use of libhfs' internal block
cache, useful for RAM file systems or systems/circumstances where the
cache may decrease performance.
* New HFS_OPT_ZERO format/mount option forces all allocated blocks to be
zero-initialized before use, for systems/circumstances in which blocks
may otherwise contain random data. (This is primarily a security feature
with a performance cost.)
Version 3.2.5
* Miscellaneous internal `const' and other minor changes.
Version 3.2.4
* Fixed a problem with the handling of catalog and extents clump sizes
(again; first fixed in 1.15b but re-introduced in 3.0b1, alas.)
* Modified `configure' once again to search for tcl.h/tk.h header files.
* Changed the OS interface to operate on full block rather than byte
offsets.
* Moved the 800K size check from hfs_format() into v_geometry().
Version 3.2.3
* Fixed a problem with the B*-tree node splitting code. This could have
caused the libhfs routines to crash under some rare circumstances.
Version 3.2.2
* Added support for "blessing" the MacOS System Folder by means of a new
field in the hfsvolent struct. A new option to `hattrib' can be used to
set this field, as can a new "bless" Tcl volume command.
* Modified `configure' to use existing Tcl/Tk configuration information
rather than reconstruct it.
Version 3.2.1
* Fixed a minor potential problem where BinHex translation might fail to
recognize the hqx header.
Version 3.2
* Fixed a problem determining medium sizes under unusual conditions.
* Modified MDB `drVCSize', `drVBMCSize', and `drCtlCSize' to new
Sequoia-supporting `drEmbedSigWord' and `drEmbedExtent'.
Version 3.1.1
* Fixed a problem related to partition locations on large media.
* Fixed a problem with suid.c on some systems.
* Fixed a problem with font selection in `xhfs'.
* Changed copyouts not to append `.txt' to text files if the filename
already contains a period.
* Fixed a few other minor problems.
Version 3.1
* `hmount' and friends now properly handle relative pathnames, even if
the current directory changes.
* Enhanced API for managing partitions: hfs_zero() will create a new,
empty partition map on any medium. hfs_mkpart() will create a new HFS
partition (if space allows) in the map. hfs_nparts() will return the
number of HFS partitions currently existing on the medium.
* hfs_mount() and hfs_format() are now more strict with the partition
number passed to them; previously this number was ignored if the medium
was not partitioned. Now the partition _must_ exist, or else 0 can be
passed to ignore any partitions and select the entire medium.
* Changed the API for hfs_create(); this routine now returns an open file
reference upon successful creation.
* Added bad block sparing to hfs_format(). This routine now requires two
additional arguments specifying a list of block numbers which are
defective on the physical medium and should be mapped out of use.
* Character set translation is now performed as well as end-of-line
translation in the "text" transfer mode. The routines convert MacOS
Standard Roman to equivalent (or near-equivalent) Latin-1 (ISO 8859-1)
sequences and vice versa. It should be noted however that these
translations are NOT reversible for all characters.
* Fixed a bug in xhfs.tcl which failed to include the helper `ctime'
procedure (fixed in hfs.tcl) after it was removed from tclhfs.c.
* Further librsrc development.
Version 3.0b2
* Changed the block cache mechanism so that consecutive blocks are read
and written in single chunks, significantly improving performance.
* Improved the efficiency of the internal routines for searching B*-trees
by reducing the number of times the record keys are unpacked from their
external format.
Version 3.0b1
* Package is now configured automatically via GNU `configure' script.
* Numerous internal changes to support automatic configuration and improve
portability, as well as reduce code size.
* Bug fix: the alternate MDB was sometimes written to the wrong location
on non-partitioned media.
* Bug fix: the Extents Overflow file could become corrupted under some
circumstances in which a heavily fragmented file is removed.
* Bug fix: it was possible for the volume allocation routine to become
caught in an infinite loop.
* Significant librsrc development. The library can now read and return
resources to an application, but cannot create or modify them. The
library can be used with or without libhfs.
* hfs_mount() now honors the software volume lock bit and makes the volume
read-only accordingly.
* Added a new hfs_vsetattr() routine to allow some volume attributes to
be modified.
* Added support for partition data blocks that do not start at the
beginning of a partition.
Version 2.1
* Further hfsck development.
* Physical blocks from the volume are now cached by the library. This
should dramatically improve performance of the programs on some systems.
* Modified the hfsvolent and hfsdirent structures to include several new
fields. The hfs_vstat(), hfs_stat(), and hfs_setattr() functions now
manipulate the new fields. Note that hfsdirent now includes a separate
union structure for files and directories.
* Fixed a problem on some systems with `xhfs' that caused it to terminate
with the message `Error: can't read "data": no such variable'. The
problem was caused by the inability to parse the system's `df' command
output.
Version 2.0
* Renamed hfs_fork() to hfs_setfork(), and added hfs_getfork().
* Modified all programs to be setuid-aware. Setuid privileges are only
engaged when opening devices as HFS volumes; this can be useful to limit
access to and/or help protect the structural integrity of HFS volumes,
for example by installing the hfsutils programs setgid. N.B. This
implementation may not be completely portable, and is isolated to the
new source file `./suid.c'.
* First non-beta release.
Version 1.19b
* Fixed a problem which prevented large volumes from being properly
formatted by hfs_format(). This should also allow the library to
correctly manipulate large volumes in certain other cases.
* Adapted the code to work with Tcl 7.6 and Tk 4.2.
* Added an HFS globbing interface to Tcl, and extended the `hfs' shell
to use it.
* Modified globbing routine to ignore Finder-invisible files.
* Rewrote `hls' and `hdir'; many UNIX-like options are now available.
* Updated the general documentation.
* Continued development of `hfsck'.
Version 1.18b
* Resolved many signed/unsigned argument passing conflicts throughout the
code. It should now compile cleanly even on very strict systems.
* Changed the interface for hfs_read() and hfs_write() to accept a void *
buffer pointer rather than demanding char *.
* Made volume file locking optional for systems that don't support it.
* Included a few other portability fixes for AIX and BeOS.
Version 1.17b
* Completed the implementation for `hattrib'; HFS file attributes (type,
creator, invisible/locked) can now be changed from the command line.
* Fixed an off-by-one error in computing catalog record key lengths.
* Fixed a problem with backslash-quoted braces during globbing.
* Improved Makefile handling.
* Regularized the handling of the volume-unmounted flag.
* Streamlined the internal and external interface header files.
* Added a `parid' field to the hfsdirent structure.
* Updated libhfs documentation.
* Implemented a better error message reporting format involving pathnames.
Version 1.16b
* Improved the robustness of the HFS path resolution routine.
* Fixed hfs_rename() to better detect the validity of destination paths.
* Changed mount-time scavenging only to mark bits in the volume bitmap,
not clear them. This reduces the risk of causing further damage to a
corrupt disk, leaving serious recovery to more advanced tools.
* Added file locking to hfs_mount() to prevent concurrent processes from
potentially creating inconsistencies in a volume.
* Added a new argument to hfs_mount() for specifying mount flags. This now
allows a volume to be explicitly mounted read-only, read-write, or don't
care (whichever is available).
* Improved detection and handling of multiple same-device mounts by a single
process.
* Improved error message reporting for all programs.
* Fixed a problem where hrenaming a volume caused it to become inaccessible
until it was hmounted again.
Version 1.15b
* Increased buffer size for native HFS-to-HFS copies to increase
performance.
* Fixed a problem verifying the existence of directory threads.
* Fixed a problem with the handling of catalog and extents clump sizes.
Version 1.14b
* The command-line programs now support filename globbing; see hfsutils(1)
for syntax details.
* File threads are now managed properly when the associated file is deleted,
moved, or renamed. However, there is no mechanism yet to explicitly create
or remove threads, or to use them in catalog searches.
* The volume bitmap is now reconstructed from the catalog and extents files
when a volume is mounted that was not previously cleanly unmounted.
* Directories may now be deleted recursively using `xhfs'.
* BinHex and MacBinary header fork size validation limitations have been
relaxed. (MacBinary spec suggested 0x007fffff ~= 8MB as maximum length?)
* Volumes are now flushed automatically by `xhfs' every 30 seconds to
reduce risk of accidental data loss.
* Begun work on `hfsck', a program to verify and correct HFS volume
consistency.
* Begun work on `librsrc', a library for manipulating the resource forks
of HFS files.
Version 1.13b
* Fixed two bad extent record key sorting bugs; these could have caused
serious problems on certain fragmented volumes.
* Fixed a problem related to MacOS default file clump size semantics.
* Implemented recursive directory copies in `xhfs'.
* Files and directories may now be renamed with a mere change of case.
* Multiple files may now be moved with `hrename'.
* A UNIX pathname of "-" in `hcopy' may now be used to mean stdin or stdout
when used as the source or destination target, respectively.
Version 1.12b
* Fix to allow mounting of some miscreant partitioned media.
* Increased copyin/copyout buffer sizes for better performance.
* Implemented -a for `hcopy' (automatic transfer mode selection.)
* HFS timestamps are now relative to the current time zone.
Version 1.11b
* UNIX-to-HFS BinHex transfers have been implemented. All transfer modes
are now fully implemented.
* The overall BinHex implementation now uses the stdio library for
somewhat better performance.
* New libhfs routines: hfs_setattr(), hfs_fsetattr() for changing file
and directory attributes (timestamps, type/creator, flags).
* The copyin routines now update the relevant file information (timestamps,
flags) for MacBinary and BinHex transfers.
* The `hvol' command now provides better output.
* Modified the installation procedure; separate targets now build and
install the separate components of the package.
* Fixed a bug in HFS filename sorting which affects the search routines;
filenames are now sorted precisely according to MacOS idiosyncrasies.
* Begun work on (but still unimplemented): hattrib, filename globbing.
Version 1.10b
* Fixed a serious bug in directory record updates; directories with names
longer than 21 characters could get corrupted.
* Implemented hfs_rename() and eliminated hfs_move(); functionality for
the latter has been included in the former.
* Added an `hrename' command. Minor changes to hcwd.c to cope with
volume name or cwd path changes.
* Minor changes to `xhfs'. Files can now be renamed with the interface.
Version 1.9b
* Modularized the libhfs code.
* Resolved more portability issues. The code should now work regardless of
the size or endianness of the host's datatypes.
Version 1.8.1b
* Fixed some portability bugs.
Version 1.8b
* More UI enhancements to `xhfs'.
* UNIX-to-HFS MacBinary II transfers have been implemented; HFS-to-HFS
copies have been implemented. Only one transfer mode (UNIX-to-HFS BinHex)
remains unimplemented.
* Replaced `hcat' with a generic `hcopy'. All transfer modes are supported.
(But note: The -a option is not yet supported.)
* Fixed a bug in the MacBinary II encoding CRC algorithm.
* Tcl hash tables are now used to maintain open files and volumes.
* Cleaned up some of the Tcl/Tk interface to aid compatibility with
various versions.
Version 1.7b
* Many more UI enhancements to `xhfs'.
* Files can now be copied from UNIX to HFS volumes with `xhfs' using either
Text or Raw mode translation.
Version 1.6b
* Fixed a bug in the catalog manipulation routines which would allow files
and directories to be created at the same level as the root folder.
* Many UI enhancements to `xhfs'. Some minor enhancements to `hfs'.
* hfs_islocked() now returns 1 if a volume is locked (read-only).
* Extended file attributes to recognize invisible files.
Version 1.5b
* All cases of B*-tree record insertion have been completed.
* B*-tree record deletion has been implemented. Files and folders may now
be created and deleted with no limitations (other than the size of the
volume.)
* New commands: hrmdir, hdel
* File writing and truncation have been implemented.
* The library now maintains its own concept of "current volume". The last
volume to be mounted is by default current; the new functions
hfs_getvol() and hfs_setvol() can be used to get and set the current
volume, respectively. All other functions will now accept a null volume
pointer to represent the current volume.
* Absolute pathnames may now refer to (mounted) volumes other than the one
specified in the call; in this event the specified volume is ignored.
Version 1.4b
* Updated the installation procedure. The Tcl and Tk programs can now be
built and installed optionally.
* Fixed a minor bug which would cause the header node to be read just
before completing a directory read.
* Mounting the same volume more than once now returns a reference to the
same volume, and does the right thing when each reference is
independently unmounted.
* Cleaned up some of the Tcl interface to deal with multiply-referenced
volumes. `xhfs' can now deal with the same volume on both sides.
* Renamed hfs_cwdid() to hfs_getcwd(), and added hfs_setcwd().
* hfs_umount() now closes all open files and directories on the volume
before unmounting it. All external references to the volume and any
open files/directories will become invalid.
* Enabled hfs_umountall() which will effectively unmount all volumes,
invalidating all external volume and file references. This is a
catch-all that should be called before a program exits. N.B.: Errors
during volume flushing and unmounting are not reported.
Version 1.3b
* Enhanced writability: B*-tree file growth has been implemented. New
directories can be created until the disk gets full.
* Added an option to `xhfs' for creating new directories.
Version 1.2b
* Enhanced writability: B*-tree node splitting has been implemented. New
directories can be created until the catalog file gets full.
* Fixed some minor bugs in version 1.1b.
Version 1.1b
* Full read-only capability.
* Limited write capability: new directories can be created only until
a catalog node gets full.
* New volumes can be created with hfs_format().

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY

How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>

along with this program; if not, write to the Free Software
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it

The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program

===============================================================================
Author: Robert Leslie <rob@mars.org>
The HFS globbing code was inspired by similar code to perform filename
globbing in Tcl by John Ousterhout.
The code to perform BinHex encoding/decoding is based on the definition of
BinHex 4.0 as written by Peter N Lewis.
The code for `hls' is loosely based on the GNU implementation of `ls'.

Basic Installation
==================
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, a file
`config.cache' that saves the results of its tests to speed up
reconfiguring, and a file `config.log' containing compiler output
(useful mainly for debugging `configure').
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If at some point `config.cache'
contains results you don't want to keep, you may remove or edit it.
The file `configure.in' is used to create `configure' by a program
called `autoconf'. You only need `configure.in' if you want to change
it or regenerate `configure' using a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. You can give `configure'
initial values for variables by setting them in the environment. Using
a Bourne-compatible shell, you can do that on the command line like
this:
CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
Or on systems that have the `env' program, you can do it like this:
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not supports the `VPATH'
variable, you have to compile the package for one architecture at a time
in the source code directory. After you have installed the package for
one architecture, use `make distclean' before reconfiguring for another
architecture.
Installation Names
==================
By default, `make install' will install the package's files in
`/usr/local/bin', `/usr/local/man', etc. You can specify an
installation prefix other than `/usr/local' by giving `configure' the
option `--prefix=PATH'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
give `configure' the option `--exec-prefix=PATH', the package will use
PATH as the prefix for installing programs and libraries.
Documentation and other data files will still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=PATH' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' can not figure out
automatically, but needs to determine by the type of host the package
will run on. Usually `configure' can figure that out, but if it prints
a message saying it can not guess the host type, give it the
`--host=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name with three fields:
CPU-COMPANY-SYSTEM
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the host type.
If you are building compiler tools for cross-compiling, you can also
use the `--target=TYPE' option to select the type of system they will
produce code for and the `--build=TYPE' option to select the type of
system on which you are compiling the package.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Operation Controls
==================
`configure' recognizes the following options to control how it
operates.
`--cache-file=FILE'
Use and save the results of the tests in FILE instead of
`./config.cache'. Set FILE to `/dev/null' to disable caching, for
debugging `configure'.
`--help'
Print a summary of the options to `configure', and exit.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`--version'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`configure' also accepts some other, not widely useful, options.

===============================================================================
NOTES ON THIS RELEASE
This release uses GNU autoconf to automatically configure the software
for installation and use on your system. This means you should not have
to modify any files by hand to get the software to compile -- if you do,
please let the author know so it can be fixed.
For general installation instructions, please read the `INSTALL' file.
There are a few special options you can give the `configure' program that
you should know about:
--with-tcl build the Tcl/Tk components
--with-tk build the Tk-based X interface `xhfs'
--disable-cli do not build or install the command-line utils
--enable-devlibs enable installation of the developer libraries
To build the Tcl tools `hfssh' and `hfs', you must use `--with-tcl'.
To build the X interface `xhfs', you must use `--with-tcl --with-tk'.
In order to build the Tcl tools you must have Tcl 7.6 or newer already
installed on your system. To build the X interface, you must have Tk 4.2
or newer installed as well.
If `configure' is unable to locate your Tcl or Tk installation, you will
have to give it a hint. It looks for the files `tclConfig.sh' and
`tkConfig.sh' (respectively) which contain all the details about your
configuration; these files were created when Tcl/Tk was installed on your
system.
To help `configure' find these files, you can specify a directory name on
the command line. For example:
./configure --with-tcl=/usr/share/tcl --with-tk=/usr/share/tk
When in doubt, wait and see if `configure' complains.
By default, the command-line utilities (hmount, hls, hcopy, etc.) are
always built and installed. If you don't want them, use `--disable-cli'.
If you want to install the developer libraries (libhfs.a, librsrc.a, and
associated header files) as well as the programs, use `--enable-devlibs'.
The libraries are not installed by default.
The `INSTALL' file contains the rest of the details you will need to
compile and install the software. Please read it!

NOTES ON "SETUID" INSTALLATION
Although the author has made some effort to make the programs in this
package somewhat setuid-safe, none are intended to be installed in such a
manner, and you do so at your own risk!
Specifically, installing the programs setuid root is a bad idea, as it will
allow anyone to attempt to open (or format) any file as an HFS volume,
disregarding the normal UNIX file permission checks.
A better idea is to modify the permissions on the necessary device files to
allow access to appropriate users. For example, if you make your floppy
device group-writable to a special group of floppy users, then only those
users will be able to access an inserted floppy disk and nothing needs to
be made setuid.
Here is an example:
% ls -l /dev/fd0 /usr/local/bin/xhfs
brw-rw---- 1 root floppy 2, 0 Sep 17 13:51 /dev/fd0
-rwxr-xr-x 1 root staff 339874 Jan 17 20:18 /usr/local/bin/xhfs
% grep floppy /etc/group
floppy:*:25:rob,thigpen
This configuration permits users `rob' and `thigpen' read/write access to
the floppy device, without needing to make any programs setuid.
Another possibility is to make some of the programs in this package setgid
(NOT setuid) to a similar group which has access to the necessary devices.
This avoids the need to add specific users to a group, since it allows
anyone to access the devices using the utilities, while still maintaining
the integrity of the data on the devices since they are not world-writable.
(A world-writable device lends itself to the possibility that someone may
corrupt some portion of it by other means and render an HFS volume
unusable, whereas limiting access only through the utilities means the
volume is unlikely to be corrupted under normal usage -- although note that
since HFS itself does not provide any file permission structure, anyone may
still modify the HFS volume in any way. The only protection here is that
the modifications must be made in an HFS-compatible way, so that the
possibility of corruption is reduced.)
Here is another example:
% ls -l /dev/fd0 /usr/local/bin/xhfs
brw-rw---- 1 root floppy 2, 0 Sep 17 13:51 /dev/fd0
-rwxr-sr-x 1 root floppy 339874 Jan 17 20:18 /usr/local/bin/xhfs
% grep floppy /etc/group
floppy:*:25:
In this case, only setgid `floppy' programs (such as `/usr/local/bin/xhfs')
are permitted access to the floppy device.
To summarize: it is suggested that the utilities NOT be installed setuid or
setgid. It is possible to install the utilities setgid as described above,
but it is NOT recommended that the utilities be installed setuid root under
any circumstances.

$Id: TODO,v 1.14 1998/11/02 22:08:22 rob Exp $
===============================================================================
General to-do items (aka bugs):
libhfs
* support HFS+ (aka Sequoia, Extended Format)
* don't allow reads from spared blocks
* further improve efficiency of b*-tree searches?
* concurrency considerations: opening same file multiple times;
performing directory manipulations on open files
* b*-tree record balancing?
* smarter block allocation algorithm
* volume full: hfs_write() should return bytes written < len, return -1
on next call?
* seek beyond end of file?
* touch directory timestamps on file updates?
* improve efficiency of bitmap operations
* improve efficiency of search operations
* CNID wrapping?
* bad block sparing by physical block
librsrc
* determine resource sizes without reading them
* support writability
hfsck
* modify libhfs to support low-level grubbing
command-line tools
* preserve timestamps (-p) for hcopy
* recursive hcopy (-r)
* allow hformat to create files and/or set size?
* write Linux utilities mkfs.hfs, fsck.hfs
* eliminate ftruncate()
* more flags for hdel (-i, -r, -f)
* glob :*:foo correctly
* glob hcopy destination HFS path?
* formalize hdisk.pl into the distribution
xhfs
* open arbitrary partitions
* rename volumes
* change file type/creator
* more support for other platforms (correct device defaults; df output)
* graphical partition map editor?
* recursive copy: map illegal directory name chars
copyin/copyout
* finish/fix timestamp preservation
* revisit buffer sizes
* remember src/dst filenames (for preserve/delete)
* allow name mangling to be optional
* don't unconditionally clobber
* delete incomplete files after failed transfers
* AppleSingle, Netatalk-/CAP-style AppleDouble?
Future wish-list:
* raw SCSI access for hideous platforms
* partitioning utility
* defragmenting utility
Acknowledged limitations:
* null characters (ASCII 0x00) not supported in filenames
* partition maps not managed with A/UX support
