changelog

创建一个符合iso-9660标准的iso文件系统

	* mkisofs.c:  Allow -A to specify application ID.  Fix usage(),
	getopt and add case switch.

	* rock.c: Fix handling of device numbers (dev_t high should only
	be used when sizeof(dev_t) > 32 bits).

	Add a bunch of changes from Manuel Bouyer.

	* diag/Makefile: New file.

	* diag/dump.c, diag/isodump.c: Use termios if system supports it.

	* (throughout): Replace all occurences of "malloc" with e_malloc.

	* mkisofs.c:  For NetBSD, attempt to increase the rlimit for
	the size of the data segment to about 33 Mb.

	* mkisofs.c (e_malloc): New function.  Calls malloc, and prints
	nice error message and exits if NULL is returned.

Sun Jan 23 19:23:57 1994  Eric Youngdale  (eric@esp22)

        * mkisofs.c, mkisofs.8, Makefile (version_string): Bump to 1.01.

    Add a bunch of stuff so that mkisofs will work on a VMS system.

	* (ALL): Change any direct use of the "st_ino" field from
	the statbuf to use a macro.

	* mkisofs.h: Define appropriate macros for both VMS and unix.

	* (ALL): Add type casts whenever we use the UNCACHED_DEV macro.

	* rock.c: Wrap a #ifndef VMS around block and character device
	stuff.

	* write.c: Add prototype for strdup if VMS is defined.

	* make.com: Script for building mkisofs on a VMS system.

	* Makefile: Include make.com in the distribution.

	* mkisofs.c: Include <sys/type.h> on VMS systems.

	* tree.c: Include <sys/file.h> and "vms.h" on VMS systems.

	* mkisofs.h (PATH_SEPARATOR, SPATH_SEPARATOR):  New macros
	that define the ascii character that separates the last directory
	component from the filename.

	* tree.c, mkisofs.c: Use them.

	* vms.c: New file.  Contains version of getopt, strdup, opendir,
	readdir and closedir.

	* vms.h: New file.  Defines S_IS* macros.  Define gmtime as
	localtime, since gmtime under VMS returns NULL.

Sat Jan 15 13:57:42 1994  Eric Youngdale  (eric@esp22)

	* mkisofs.h (transparent_compression): New prototype.

	* mkisofs.c (transparent_compression): Declare, use
	'-z' option to turn on.

	* tree.c: Change TRANS.TBL;1 to TRANS.TBL (version gets
	added later, if required).

	* rock.c: If transparent compression requested, verify
	file is really suitable (check magic numbers), and extract
	correct file length to store in SUSP record.

Sat Jan 15 01:57:42 1994  Eric Youngdale  (eric@esp22)

	* write.c (compare_dirs): Bugfix for patch from Jan 6.

	* mkisofs.h (struct directory_entry): Add element total_rr_attr_size.
	(struct file_hash): Add element ce_bytes.

	* write.c (iso_write): Update last_extent_written, as required,
	and check it against last_extent as a sanity check.
	(generate_one_directory): If ce_bytes is non-zero, allocate
	a buffer and fill it with the CE records.  Also, update
	the extent and offset entries in the CE SUSP field and
	output after directory is written.
	(assign_directory_addresses): Allow for CE sectors after each
	directory.

	* tree.c (sort_n_finish): Set field ce_bytes by summing
	the sizes of all CE blocks in each files RR attributes.
	Do not count these bytes for main directory.

	* rock.c (generate_rock_ridge_attributes): Generate
	CE entries to break up large records into manageable sizes.
	Allow long names to be split, and allow long symlinks to be split.
	Allow splitting before each SUSP field as well, to make
	sure we do not screw outselves.

Thu Jan  6 21:47:43 1994  Eric Youngdale  (eric@esp22)

    Bugfix.

	* write.c (compare_dirs): Only compare directory names up to
	the ';' for the version number.

    Add four new options: (1) Full 31 character filenames,
    (2) Omit version number, (3) Omit trailing period from filenames,
    (4) Skip deep directory relocation.

	* iso9660.h: Allow 34 characters for filename.

	* mkisofs.8: Update for new options.

	* mkisofs.c: Add flag variables for new options.
	Mention new options in usage(), tell getopt about
	new options, and set appropriate flags when
	new options are specified.

	* mkisofs.c (iso9660_file_length): Implement new options.

	* mkisofs.h: Declare flag variables for new options.

	* tree.c (sort_n_finish): Increase declaration of newname and
	rootname to 34 characters.  If full_iso9660_filenames in effect,
	use different rules for making unique names.

	* tree.c (scan_directory_tree): Use RR_relocation_depth instead of
	constant for threshold for starting deep directory relocation.

Wed Jan  5 01:32:34 1994  John Brezak ([e-mail])

	* Makefile.bsd: New file.  For NetBSD.

	* rock.c, tree.c: Do not include sys/sysmacros.h for NetBSD.

Fri Dec 31 13:22:52 1993  Eric Youngdale  (eric@esp22)

        * mkisofs.c, mkisofs.8, Makefile (version_string): Bump to 1.00.

	* tree.c (scan_directory_tree): Handle case where we do not
	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])

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.

	* hash.c: Add add_directory_hash, find_directory_hash functions.

	* mkisofs.h: Add prototypes.

Sat Sep 25 14:26:31 1993  Eric Youngdale  (eric@kafka)

        * mkisofs.c, Makefile (version_string): Bump to 0.92.

	* 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.
