	have permissions to open a directory.

	* write.c (xfwrite): New function - wrapper for fwrite,
	except that we print message and punt if write fails.

	* write.c: Move include of mkisofs.h and iso9660.h until after
	string.h and stdlib.h is included.

	* write.c: Do not attempt to use strerror on sun systems.

Thu Dec 9  13:17:28 1993  R.-D. Marzusch ([e-mail])

        * exclude.c, exclude.h: New files.  Contains list of files to
	exclude from consideration.

	* Makefile: Compile exclude.c, add dependencies to other files.

	* mkisofs.8: Describe -x option.

	* mkisofs.c: Include exclude.h, handle -x option.


Fri Dec 10 01:07:43 1993  Peter van der Veen ([e-mail])
 
 	* mkisofs.c, mkisofs.h: Moved declaration of root_record.
 
 	* mkisofs.h: Added prototype for get_733().
 
 	* write.c(iso_write), tree.c, rock.c(generate_rock_ridge_attributes):
 	Added defines for QNX operation system
 
 	* rock.c(generate_rock_ridge_attributes): symbolic links should
 	not have CONTINUE component flag set unless there are multiple
 	component records, and mkisofs does not generate these.
 	st_ctime was stored as the creation time, changed to attribute time.
 	QNX has a creation time, so that is stored as well under QNX.
 
Thu Oct 28 19:54:38 1993  Eric Youngdale  (eric@kafka)

        * mkisofs.c, Makefile (version_string): Bump to 0.99.

	* write.c(iso_write): Put hour, minute, second into date fields in
	volume descriptor.

	* write.c (iso_write): Set file_structure_version to 1, instead of
	' ' (Seems to screw up Macs).

Sun Oct 17 01:13:36 1993  Eric Youngdale  (eric@kafka)

        * mkisofs.c, Makefile (version_string): Bump to 0.98.

    Increment nlink in root directory when rr_moved directory is present.

        * tree.c (increment_nlink): New function.

	* tree.c (finish_cl_pl_entries): Call increment_nlink for all
	references to the root directory.

	* tree.c (root_statbuf): New variable.

	* tree.c (scan_directory_tree): Initialize root_statbuf when we
	stat the root directory.

	* tree.c (generate_reloc_directory): Use root_statbuf when
	generating the Rock Ridge stuff for the ".." entry in the
	reloc_dir.

	* tree.c (scan_directory_tree): Use root_statbuf when generating
	the ".." entry in the root directory.

Sat Oct 16 10:28:30 1993  Eric Youngdale  (eric@kafka)

    Fix path tables so that they are sorted.

	* tree.c (assign_directory_addresses): Move to write.c

	* write.c (generate_path_tables): Create an array of pointers to
	the individual directories, and sort it based upon the name and
	the parent path table index.  Then update all of the indexes and
	repeat the sort until the path table indexes no longer need to be
	changed, and then write the path table.

    Fix problem where hard links were throwing off the total extent count.

	* write.c (iso_write): Call assign_file_addresses, and then
	use last_extent to determine how big the volume is.

	* write.c (generate_one_directory): Decrement n_data_extents
	for hard links to non-directories so that the expected number
	of extents is written correctly.

	* write.c(assign_file_addresses): New function.

Fri Oct 15 22:35:43 1993  Eric Youngdale  (eric@kafka)

    The standard says we should do these things:

	* tree.c (generate_reloc_directory): Add RR attributes to
	the rr_moved directory.

	* mkisofs.c(main): Change ER text strings back to recommended
	values.

Tue Oct 12 21:07:38 1993  Eric Youngdale  (eric@kafka)

        * mkisofs.c, Makefile (version_string): Bump to 0.97.  

	* tree.c (scan_directory_tree): Do not insert PL entry into
	root directory record (i.e. !parent)

	* tree.c (finish_cl_pl_entries): Do not rely upon name
	comparison to locate parent - use d_entry->self instead,
	which is guaranteed to be correct.

	* mkisofs.h: New variable n_data_extents.

	* tree.c: Declare and initialize n_data_extents to 0.
	(scan_directory_tree) for non-directories, add
	ROUND_UP(statbuf.st_size) to n_data_extents.
	(sort_n_finish): Increment n_data_extents for translation tables,
	as appropriate.

	* write.c(iso_write): Add n_data_extents to the
	volume_space_size field.

	* hash.c(add_hash): If size != 0 and extent == 0, or
	if size == 0 and extent != 0, then complain about
	inserting this into the hash table.  Kind of a sanity check.

Sat Oct  9 16:39:15 1993  Eric Youngdale  (eric@kafka)

        * mkisofs.c, Makefile (version_string): Bump to 0.96.  

	Numerous bugfixes, thanks to a one-off disc from [e-mail].

	* write.c(generate_one_directory): Wait until after we have
	filled in the starting_extent field to s_entry before calling
	add_hash.  This fixes a problem where the hash table gets an
	extent of 0 for all regular files, and this turns up when you have
	hard links on the disc. (The hash table allows us to have each
	hard link point to the same extent on the cdrom, thereby saving
	some space).

	* tree.c(scan_directory_tree): Set statbuf.st_dev and
	statbuf.st_ino to the UNCACHED numbers for symlinks that we
	are not following.  This prevents the function find_hash from
	returning an inode that cooresponds to the file the symlink points
	to, which in turn prevents generate_one_directory from filling in
	a bogus file length (should be zero for symlinks).

	* tree.c(scan_directory_tree): Always call lstat for the file
	so that non-RockRidge discs get correct treatment of symlinks.
	Improve error message when we ignore a symlink on a non-RR disc.
	
	* write.c(generate_one_directory): Set fields for starting_extent
	and size in the "." and ".." entries before we add them to the
	file hash.  Fixes problems with incorrect backlinks for second
	level directories.

Wed Oct  6 19:53:40 1993  Eric Youngdale  (eric@kafka)

	* write.c (write_one_file): Print message and punt if we are
	unable to open the file.

	* tree.c(scan_directory_tree): For regular files, use the access
	function to verify that the file is readable in the first place.
	If not, issue a warning and skip it.  For directories, it probably
	does not matter, since we would not be able to descend into them
	in the first place.

Wed Sep 29 00:02:47 1993  Eric Youngdale  (eric@kafka)

        * mkisofs.c, Makefile (version_string): Bump to 0.95.

	* write.c, tree.c: Cosmetic changes to printed information.

        * tree.c(scan_directory_tree): Set size to zero for
	special stub entries that correspond to the
	relocated directories.  Hopefully last big bug.

	* mkisofs.h: Change TABLE_INODE, UNCACHED_* macros
	to be 0x7fff... to be compatible with signed datatypes.

Mon Sep 27 20:14:49 1993  Eric Youngdale  (eric@kafka)

        * mkisofs.c, Makefile (version_string): Bump to 0.94.

	* write.c (write_path_tables): Actually search the
	directory for the matching entry in case we renamed
	the directory because of a name conflict.

	* tree.c(scan_directory_tree): Take directory_entry pointer
	as second argument so that we can create a backpointer
	in the directory structure that points back to the original
	dir.

	* mkisofs.c: Fix call to scan_directory_tree to use new calling
	sequence.

	* write.c(generate_one_directory): Punt if the last_extent counter
	ever exceeds 700Mb/2048.  Print name of responsible file,
	extent counter, and starting extent.  Perhaps we can catch it in
	the act.

Sun Sep 26 20:58:05 1993  Eric Youngdale  (eric@kafka)

        * mkisofs.c, Makefile (version_string): Bump to 0.93.

	* tree.c(scan_directory_tree): Handle symlinks better.  Either
	leave them as symlinks, or erase any trace that they were a
	symlink but do not do it 1/2 way as before.  Also, watch for
	directory loops created with symlinks.

	* mkisofs.h: Add new flag follow_links.

	* mkisofs.c: Add command line switch "-f" to toggle follow_links.

	* mkisofs.8: Document new switch.

	* tree.c: Add code to handle symlinks using new flag.

	* mkisofs.c: Make sure path is an actual directory before trying
	to scan it.

	* mkisofs.h: Add DECL and FDECL? macros for sparc like systems.
	Do proper define of optind and optarg under SVr4.

	* tree.c: Change translation table name from YMTRANS.TBL to TRANS.TBL.

	* mkisofs.c: Neaten up message in extension record when RRIP is
	in use.

	* Throughout - change all function declarations so that
	traditional C compilers (i.e. sparc) will work.

	* Makefile: Change to use system default C compiler.

	* mkisofs.c: Add some stuff so that this will compile under VMS.
	Many things missing for VMS still.

	* iso9660.h: Do not use zero length array in struct definition.

	* tree.c (sort_n_finish): Account for this.

	* Change copyright notice.

        * mkisofs.c, Makefile (version_string): Bump to 0.91.

	* mkisofs.h: Only  include sys/dir.h for linux.  Other systems
	will need other things.

        * mkisofs.c, Makefile (version_string): Bump to 0.8.

	* rock.c: Do not mask off write permissions from posix file modes.

Wed Aug 18 09:02:12 1993  Eric Youngdale  (eric@kafka)

        * mkisofs.c, Makefile (version_string): Bump to 0.7.

        *  rock.c: Do not  write  NM field  for . and .. (redundant and a
	waste of space).

	* mkisofs.c: Take -P and -p options for publisher and preparer id
	fields.

	* write.c: Store  publisher and preparer id  in  volume
	descriptor.

	* rock.c: Write  optional  SP field to identify  SUSP.  Write
	optional CE field to point to the extension header.

	* tree.c: Request  SP and  CE fields be added to root directory.

        * tree.c: Fix bug in name conflict resolution.

        * write.c: Fill in date fields in the  colume descriptor.

        * write.c (write_one_file): If the file is large enough, write  in
	chunks of 16 sectors to improve performance.

	* hash.c (add_hash, find_hash, etc): Do  not hash s_entry, instead
	store relevant info in hash structure (we free s_entry  structs as
	we write files, and we need to have access to the hash table  the
	whole  way through.

	* write.c: Add a few statistics about directory sizes, RR sizes,
	translation table sizes, etc.

	* tree.c: Use major, not MAJOR.  Same for minor.  Define S_ISSOCK
	and S_ISLNK if not defined.

	* rock.c: Define S_ISLNK if not defined.

	* mkisofs.c: Print out max memory usage.  Fix bug in call to getopt.

        * mkisofs.c, Makefile (version_string): Bump to 0.6.

	* tree.c: Simplify the calculation of isorec.len,  isorec.name_len
	and the calculation of the path table sizes by doing it all at
	one point after  conflict resolution is done.

	* tree.c: scan_directory_tree is now  responsible for generating
	the line that goes into the YMTRANS.TBL file.  These lines are
	collected later  on into something that will be dumped to the
	file. Correctly handle all of the special file types.

Mon Aug 16 21:59:47 1993  Eric Youngdale  (eric@kafka)

        * mkisofs.c, Makefile (version_string): Bump to 0.5.

	* mkisofs.c: Add -a option  (to force all files to be
	transferred).  Remove find_file_hash stuff.

	* write.c: Pad length even if Rock Ridge is not in use.

	* hash.c: Rewrite hash_file_* stuff so that it  can be used to
	easily  detect (and look up) filenames that have been  accepted
	for use  in this directory.  Used for name collision detection.

	* tree.c (sort_n_finish): If two names collide, generate a unique
	one (verified with the hash routines).  Change the lower priority
	name if there is a difference.

	YMTRANS.TBL.  (scan_directory_tree) Call it.

	* mkisofs.c (iso9660_file_length): Call find_file_hash to see
	if translated name is specified.  If so, use it.

	flush_file_hash): New functions for hashing stuff from
	YMTRANS.TBL.

	* mkisofs.h: Add a bunch of prototypes for the new functions.

	been generated, and extent numbers assigned.

	* write.c (generate_one_directory): Update s_entry->size  for
	directories (as well as isorec.size).

	* rock.c:  Add  code to generate CL, PL, and RE entries.  The
	extent numbers for the CL and PL  entries are  NULL, and these
	are filled in  later once we know where they actually belong.

	* mkisofs.h: Add parent_rec to directory_entry.  Used to fix CL/PL
	stuff.

	* tree.c (scan_directory_tree): Set  flag to generate  CL/PL/RE
	entries  as required, update sizes as well.

Fri Aug 13 19:49:30 1993  Eric Youngdale  (eric@kafka)

	for sort_n_finish, add  third parameter  to  scan_directory_tree
	(for true parent, when directories are relocated).

	* mkisofs.c (main): Modify call to scan_directory_tree.  Call
	sort_n_finish for reloc_dir.

	* tree.c (sort_n_finish): New function - moved code from
	scan_directory_tree. 

	* tree.c (generate_reloc_directory): New function.  Generate
	directory to hold relocated directories.

	* tree.c (scan_directory_tree): Strip leading directories when
	generating this_dir->name.  If depth is  too great,  then move
	directory to reloc_dir (creating if it does not exist, and leave
	a dummy (non-directory) entry  in the regular directory  so that
	we can eventually add the required Rock Ridge record.

	* tree.c (scan_directory_tree): Use s_entry instead of sort_dir,
	assign to this_dir->contents sooner.

Thu Aug 12 22:38:17 1993  Eric Youngdale  (eric@kafka)

	* mkisofs.c (usage): Fix syntax.

	* mkisofs.c (main): Add new argument to scan_directory_tree

	* tree.c (scan_directory_tree): If directory is at  depth 8 or
	more, create rr_moved directory in main directory.
