## 05.dpatch by Joerg Jaspert <joerg@debian.org>
##
## All lines beginning with `## DP:' are a description of the patch.
## DP: Adds the zisofs_tools to the build tree.
## DP: The zisofs filesystem is an extension to the ISO9660 filesystem
## DP: that allows files, on a file-by-file basis, to be stored compressed
## DP: and decompressed in real time. The zisofs filesystem is supported by
## DP: recent versions of Linux (2.4.14 or later). Legacy systems can still
## DP: read uncompressed files. zisofs-tools contains the tools necessary to
## DP: create such a compressed ISO9660 filesystem and to read compressed
## DP: files on a legacy system.

+Changes in zisofs-tools-1.0.4:
+
+       Update the documentation.
+
+Changes in zisofs-tools-1.0.3:
+
+       Update cdrtools patch.
+
+Changes in zisofs-tools-1.0.2:
+
+       Add "make install" target :)
+
+Changes in zisofs-tools-1.0.1:
+
+       By default, abort if file modes, times and ownership cannot be
+       set.  Since this isn't always possible, add new option
+       -s/--sloppy to suppress this error.
+
+       Fix man page typo, and add a BUGS section.
+
+       Remove problems with extremely long symlinks.
+
+       Move all command line options into common "opt" structure.
+
+       Fix bug in command line parsing: -z option not recognized.
+
+
+Changes in zisofs-tools-1.0:
+
+       Restructured code; now split into a number of modules.
+
+       Use autoconf for configuration.
+
+       Add support for long options if the platform has
+       getopt_long().
+
+       Support compiling on systems without lchown().
+
+       Support the following new options:
+         -x    Don't descend into other filesystems
+         -X    Same as -x, but don't create mount point directories
+         -l    Don't descend into any subdirectories
+         -L    Same as -l, but don't create stub directories
+         -F    Allow compression or decompression of single files.
+         -V    Explicitly set the verbosity.
+         -w    Display program version.
+
+         Update the mkisofs patch to warn if -z is specified without
+         -r/-R.

+.TH MKZFTREE "1" "30 July 2001" "zisofs-tools" "H. Peter Anvin"
+.SH NAME
+mkzftree \- Create a zisofs/RockRidge compressed file tree
+.SH SYNOPSIS
+.B mkzftree
+[\fIOPTIONS\fR]... \fIINPUT\fR \fIOUTPUT\fR
+.SH DESCRIPTION
+.PP
+Takes an input file tree (\fIINPUT\fR) and create a corresponding
+compressed file tree (\fIOUTPUT\fR) that can be used with an
+appropriately patched
+.BR mkisofs (8)
+to create a transparent-compression ISO 9660/Rock Ridge filesystem using
+the "ZF" compression records.
+.RP
+.TP
+\fB\-f\fP, \fB\-\-force\fP
+Always compress all files, even if they get larger when compressed.
+.TP
+\fB\-z\fP \fIlevel\fP, \fB\-\-level\fP \fIlevel\fP
+Select compression level (1-9, default is 9).  Lower compression
+levels are faster, but typically result in larger output.
+.TP
+\fB\-u\fP, \fB\-\-uncompress\fP
+Uncompress an already compressed tree.  This can be used to read a
+compressed filesystem on a system which cannot read them natively.
+.TP
+\fB\-p\fP \fIparallelism\fP, \fB\-\-parallelism\fP \fIparallelism\fP
+Compress in parallel.  The
+.I parallelism
+value indicates how many compression threads are allowed to run.
+.TP
+\fB\-x\fP, \fB\-\-one-filesystem\fP
+Do not cross filesystem boundaries, but create directory stubs at
+mount points.
+.TP
+\fB\-X\fP, \fB\-\-strict-one-filesystem\fP
+Do not cross filesystem boundaries, and do not create directory stubs
+at mount points.
+.TP
+\fB\-C\fP \fIpath\fP, \fB\-\-crib-path\fP \fIpath\fP
+Steal ("crib") files from another directory if it looks (based on
+name, size, type and modification time) like they match entries in the
+new filesystem.  The "crib tree" is usually the compressed version of
+an older version of the same workload; this thus allows for
+"incremental rebuilds" of a compressed filesystem tree.  The files are
+hardlinked from the crib tree to the output tree, so if it is
+desirable to keep the link count correct the crib path should be
+deleted before running \fBmkisofs\fP.  The crib tree must be on the
+same filesystem as the output tree.
+.TP
+\fB\-l\fP, \fB\-\-local\fP
+Do not recurse into subdirectories, but create the directories
+themselves.
+.TP
+\fB\-L\fP, \fB\-\-strict-local\fP
+Do not recurse into subdirectories, and do not create directories.
+.TP
+\fB\-F\fP, \fB\-\-file\fP
+Indicates that \fIINPUT\fP may not necessarily be a directory; this
+allows operation on a single file.  Note especially that if \fI\-F\fP
+is specified, and \fIINPUT\fP is a symlink, the symlink itself will be
+copied rather than whatever it happens to point to.
+.TP
+\fB\-s\fP, \fB\-\-sloppy\fP
+Treat file modes, times and ownership data as less than precious
+information and don't abort if they cannot be set.  This may be useful
+if running
+.B mkisofs
+on an input tree you do not own.
+.TP
+\fB\-v\fP, \fB\-\-verbose\fP
+Increase the program verbosity.
+.TP
+\fB\-V\fP \fIvalue\fP, \fB\-\-verbosity\fP \fIvalue\fP
+Set the program verbosity to
+.IR value .
+.TP
+\fB\-q\fP, \fB\-\-quiet\fP
+Issue no messages whatsoever, including error messages.  This is the same
+as specifying
+.IR "\-V\ 0" .
+.TP
+\fB\-h\fP, \fB\-\-help\fP
+Display a brief help message.
+.TP
+\fB\-w\fP, \fB\-\-version\fP
+Display the release version.
+.SH BUGS
+Long options (beginning with \fI\-\-\fP) may not work on all systems.
+See the message printed out by \fImkzftree\ \-h\fP to see if this
+applies to your system.
+.PP
+Inode change times (ctimes) are not copied.  This is a system
+limitation and applies to all file copy programs.
+.PP
+If using the parallel option (\fI\-p\fP) the access times (atimes) on
+directories may or may not be copied.  If it is important that the
+atimes on directories are copied exactly, avoid using \fI\-p\fP.

+ * mkzffile.c
+ *
+ *     - Generate block-compression of files for use with
+ *       the "ZF" extension to the iso9660/RockRidge filesystem.
+ *
+ *       The file compression technique used is the "deflate"
+ *       algorithm used by the zlib library; each block must have a
+ *       valid (12-byte) zlib header.  In addition, the file itself
+ *       has the following structure:
+ *
+ *       Byte offset   iso9660 type    Contents
+ *         0           (8 bytes)       Magic number (37 E4 53 96 C9 DB D6 07)
+ *         8           7.3.1           Uncompressed file size
+ *        12           7.1.1           header_size >> 2 (currently 4)
+ *        13           7.1.1           log2(block_size)
+ *        14           (2 bytes)       Reserved, must be zero
+ *
+ * The header may get expanded in the future, at which point the
+ * header size field will be used to increase the space for the
+ * header.
+ *
+ * All implementations are required to support a block_size of 32K
+ * (byte 13 == 15).
+ *
+ * Note that bytes 12 and 13 and the uncompressed length are also
+ * present in the ZF record; THE TWO MUST BOTH BE CONSISTENT AND
+ * CORRECT.
+ *
+ * Given the uncompressed size, block_size, and header_size:
+ *
+ *     Nblocks := ceil(size/block_size)
+ *
+ * After the header follow (nblock+1) 32-bit pointers, recorded as
+ * iso9660 7.3.1 (littleendian); each indicate the byte offset (from
+ * the start of the file) to one block and the first byte beyond the
+ * end of the previous block; the first pointer thus point to the
+ * start of the data area and the last pointer to the first byte
+ * beyond it:
+ *
+ *     block_no := floor(byte_offset/block_size)
+ *
+ *     block_start := read_pointer_731( (header_size+block_no)*4 )
+ *     block_end   := read_pointer_731( (header_size+block_no+1)*4 )
+ *
+ * The block data is compressed according to "zlib".

+
+User tools for zisofs:
+
+The user tools for zisofs come in two parts: a utility "mkzftree" and
+a modification to mkisofs, which is part of the cdrtools package.  The
+mkisofs change has been integrated in the cdrtools distribution as of
+cdrtools-1.11a20; a patch for cdrtools-1.11a09 which is also tested
+and working on cdrtools-1.10 is included with this package if you
+insist on running an older version.
+
+
+First create a directory tree containing compressed files:
+
+       mkzftree input_dir compressed_dir
+
+mkzftree will not overwrite an existing directory; you may want to "rm
+-rf" the directory tree if you are doing this from a script:
+
+Second, invoke the patched mkisofs with the -z option:
+
+       mkisofs -z -R [other options] -o compressed.iso compressed_dir
+
+IMPORTANT: you *must* enable RockRidge (-R or -r) since this is an
+extensions to the RockRidge specification.  Without RockRidge, -z will
+have no effect.
+
+Note that if there are files you do not want compressed (for example,
+files involved in booting, or README files you want to be readable
+under all circumstances) you can simply put them in a separate tree
+and not run mkzftree on that tree.
+
+mkzftree will not compress files that end up larger when compressed;
+if you want it to compress the files anyway, you can give the -f
+option to mkzftree.
+
+mkzftree also accepts a -u option (uncompress), which can be used to
+convert a compressed tree back to normal form.  This can be used to
+read a zisofs CD-ROM on a machine without zisofs kernel support.
+
+This version of mkzftree supports a -p option (parallelize.)
+Specifying -p and a parallelism (e.g. -p4) allows files (up to the
+number specified) to compress in parallel.  Depending on your setup
+and your data set size, this might speed things up if you are not
+completely I/O bound.  Use -p0 to completely disable parallel
+execution; this is the default.
