 - 9th Dec 2008 Our project received a donation from Thomas Weber.
 
+- 2nd Jan 2009 libburn-0.6.0 allows to format BD-R and to write to either
+  formatted or unformatted BD-R.
+
+- 6th Jan 2009 libisoburn-0.3.2. xorriso can produce and execute commands for
+  mounting older sessions from all kinds of media. Pseudo-drives outside the
+  /dev/ tree can be addressed without prefix "stdio:". 
+
+- 20th Feb 2009 libburn-0.6.2 source release now compiles out of the box
+  on FreeBSD.
+
+- 28 Feb 2009 libisofs-0.6.14 can record ACLs and Extended Attributes xattr
+  in its ISO images. 
+
+- 01 Mar 2009 libisoburn-0.3.4. xorriso makes use of the ACL and xattr
+  capabilities provided by libisofs for xorriso backup features.
+
+- 11 Mar 2009 libisofs-0.6.16 of libisofs fixes two bugs which on Solaris
+  prevented to navigate the ISO images by ".." and to recognize the Rock Ridge
+  extensions of ISO images. The ban to build libisofs on operating systems
+  other than Linux and FreeBSD has been lifted.
+
+- 13 Mar 2009 libburn-0.6.4 got a dummy adapter for SCSI/MMC command transport.
+  It will show no drives and thus libburn will only be able to perform
+  operations on "stdio:" pseudo drives. Nevertheless this allowed to lift the
+  ban to build libburn on operating systems other than Linux and FreeBSD.
+
+- 16 Mar 2009 libisoburn-0.3.6: xorriso uses RRIP version 1.10 as default 
+  in order to be mountable where mkisofs images are mountable.
+
+- 17 Apr 2009 libisofs-0.6.18 introduces content filtering of data files.
+  Built-in filters allow compression to formats gzip and zisofs. External
+  filter processes allow arbitrary data conversions like encryption.
+
+- 19 Apr 2009 libisoburn-0.3.8 makes use of the new libisofs capability to
+  perform content filtering of data files.
+
+- 08 May 2009 libburn-0.6.6 fixes a bug with aborting on broken output pipe
+  and a bug with device scan on FreeBSD.
+
+- 31 May 2009 libisofs-0.6.20 can record hard link relations in ISO images
+  and offers support with restoring them to disk. Current Linux kernels will
+  mount images with such hard links but will attribute a unique inode number
+  to each file.
+
+- 28 Jun 2009 libisoburn-0.4.0: xorriso can record and restore hard link
+  relations of files. Performance of data reading has been improved. Option
+  -find now supports logical operators with its tests.
+
+- 14 Jul 2009 libburn-0.6.8 fixes bugs and shortcommings with old MMC-1 drives
+  and with large SCSI bus numbers as handed out by Linux for USB drives.
+
+- 20 Jul 2009 libisoburn-0.4.0.pl01 fixes a regression in xorriso which caused
+  data loss in older sessions if xorriso was used underneath growisofs.
+  Affected are releases since libisoburn-0.3.2 in january 2009.
+
+- 25 Aug 2009 libisofs-0.6.22 can record MD5 checksums for the whole session
+  and for each single data file. Checksum tags allow to verify superblock and
+  directory tree before importing them.
+
+- 27 Aug 2009 libburn-0.7.0 allows to calm down a drive and to inquire its
+  supported profiles. It works around some pitfalls with U3 enhanced memory
+  sticks which emulate a CD-ROM.
+
+- 27 Aug 2009 libisoburn-0.4.0.pl00 can record MD5 checksums by which one may
+  verify the session or single data files in the image. When comparing image
+  files with files in the local filesystem, the MD5 sums avoid the need for
+  reading file content from the image.
+
+- 22 Sep 2009 libisoburn-0.4.0.pl01 fixes a bug in xorriso option -cut_out.
+
+- 08 Oct 2009 libisofs-0.6.24 fixes a bug which could cause the loss of blanks
+  in file names when a new session got added to an ISO image. With names
+  shorter than 251 characters this happened only to trailing blanks.
+
+- 08 Oct 2009 libisoburn-0.4.0.pl02 fixes bugs with xorriso option -for_backup,
+  with xorrisofs -help, and with xorrecord -help.
+
+- 12 Oct 2009 libburn-0.7.2 fixes a bug with CD TAO multi-track dummy sessions.
+  It can retrieve media product info and can process track input which was
+  prepared for CD-ROM XA Mode 2 Form 1. cdrskin now performs option -minfo.
+
+- 28 Oct 2009 libisoburn-0.4.4 fixes a bug with cdrecord emulation and
+  introduces new information options about media type and ISO image id strings.
+  On Linux it helps with mounting two sessions of the same media
+  simultaneously.
+
+- 12 Nov 2009 libburn-0.7.2.pl01 works around problems with Pioneer DVR-216D.
+  DVD-R runs made the drive stuck. Ejecting the tray did not work properly.
+
+- 06 Dec 2009 libburn-0.7.4 works around problems with newer DVD burners,
+  provides throughput enhancements with hampered busses on Linux, and new
+  API calls to log SCSI commands and to control the libburn fifo.

+Explicite formatting is done by 04h FORMAT UNIT. Its data payload consists
+of a Format List Header and a Format Descriptor. It is advisable to set
+the Immed bit and the FOV bit in header byte number 1. The descriptor should
+be a copy of a descriptor from 23h READ FORMAT CAPACITIES but the size may be
+adjusted within a certain range.
+(mmc5r03c.pdf 6.5, 6.5.3.2, 6.5.3.3)
+
+Format type 00h creates SRM layouts with a default number of spares (or
+eventually RRM) chosen by the format sub-type:
+  00b = SRM with support for POW
+  01b = SRM without POW (but with some spares for defect management)
+  10b = (RRM)
+(mmc5r03c.pdf 6.5.4.2.1.6)
+
+Format type 32h uses the same sub-types but allows to allocate non-default
+amounts of spares. Similar to BD-RE format 31h, three format descriptors are
+offered: #1: default size, #2: maximum spare area, #3: minimal spare.
+The size may be chosen within that range.
+
+The sense behind the Type Dependent Parameters is obscure
+to me. Best will be to set ISA_V and TDMA_V to 0.

+-------------------------------------------------------------------------------
+Writing a session in SRM:
+
+The procedure and constraints for writing BD-R SRM-POW are very similar to
+DVD+R. libburn flatly re-uses its DVD+R code except the Close Function for
+finalizing a disc.
+
+In short:
+If all written sessions are closed, then there is exactly one NWA.
+In the beginning there is an empty session and track. A new track can be
+written either with pre-announced size (by RESERVE TRACK) or open-end by
+simply starting to write to the NWA. When done the track gets closed by
+close function 001b. Then either session or disc gets closed depending on
+the Close Function used:
+- Close Function 010b closes the session and keeps the media appendable
+  (same as with DVD+R)
+- Close Function 110b finalizes the media and makes it read-only.
+  (differs from libburn DVD+R procedure which uses 101b)
+
+-------------------------------------------------------------------------------
+Pseudo-OverWrite POW: (no used yet by libburn)
+
+This enhancement of SRM emulates overwriting of existing data blocks.
+(mmc5r03c.pdf 4.5.3.5.4)
+
+POW establishes a virtual vLBA space on top of the real address space rLBA.
+All read and write commands deal with vLBA. It seems that track NWAs are
+assumed to be identical in vLBA space and in rLBA space.
+It is not clear whether one may write to vLBA blocks which are neither written
+yet nor at one of the track NWAs. Probably not, or else one could make NWAs run
+into vLBAs which are associated with older rLBAs.
+
+Replacing invalidated blocks consumes addresses in rLBA space at the NWA of
+some track. I.e. no spares are consumed by POW. Nevertheless it is costly by
+a special map called Orphanage. It covers rLBA which have been consumed
+by differing vLBAs. It never shrinks and can grow with each write to remapped
+addresses.
+To avoid heavy Orphanage growth it is advised to write mostly to vLBA which
+still coincide with their rLBA. E.g. those addresses which have neither been
+written as rLBA nor as vLBA yet. So one should begin the vLBA of new sessions
+at the NWA of a sufficiently sized track.

+   This code module implements the production of RSPC parity bytes (P- and Q-
+   parity) and the scrambling of raw CD-ROM sectors as specified in ECMA-130:
+     http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-130.pdf
+
+   The following statements about Galois Fields have been learned mostly from
+     http://www.cs.utk.edu/~plank/plank/papers/CS-96-332.pdf
+   by James S. Plank after an e-mail exchange with Norbert Preining.
+
+   The output has been compared with the output of the old code of libburn
+   which was labeled "borrowed HEAVILY from cdrdao" and claimed by Joerg
+   Schilling to stem from code by Heiko Eissfeldt.

+   Note: In this text, "^" denotes exponentiation and not the binary exor
+         operation. Confusingly in the C code "^" is said exor.
+   Note: This is not C1, C2 which is rather mentioned in ECMA-130 Annex C and
+         always performed inside the drive.
+   -------------------------------------------------------------------------
+
+
+                            RSPC resp. P- and Q-Parity
+
+   ECMA-130 Annex A prescribes to compute the parity bytes for P-columns and
+   Q-diagonals by RSPC based on a Galois Field GF(2^8) with enumerating
+   polynomials x^8+x^4+x^3+x^2+1 (i.e. 0x11d) and x^1 (i.e. 0x02).
+   Bytes 12 to 2075 of a audio-sized sector get ordered in two byte words
+   as 24 rows and 43 columns. Then this matrix is split into a LSB matrix
+   and a MSB matrix of the same layout. Parity bytes are to be computed
+   from these 8-bit values.
+   2 P-bytes cover each column of 24 bytes. They get appended to the matrix
+   as rows 24 and 25.
+   2 Q-bytes cover each the 26 diagonals of the extended matrix.
+
+   Both parity byte pairs have to be computed so that extended rows or
+   diagonals match this linear equation:
+      H x V = (0,0)
+   H is a 2-row matrix of size n matching the length of the V ectors
+     [   1        1     ...   1   1 ]
+     [ x^(n-1)  x^(n-2)      x^1  1 ]
+   Vp represents a P-row. It is a byte vector consisting of row bytes at
+   position 0 to 23 and the two parity bytes which shall be determined
+   at position 24 and 25. So Hp has 26 columns.
+   Vq represents a Q-diagonal. It is a byte vector consisting of diagonal
+   bytes at position 0 to 42 and the two parity bytes at position 43 and 44.
+   So Hq has 45 columns. The Q-diagonals cover P-parity bytes.
+
+   By applying some high school algebra one gets the parity bytes b0, b1 of
+   vector V = (n_payload_bytes, b0 , b1) as
+
+     b0 = ( H[n] * SUM(n_payload_bytes) - H[0..(n-1)] x n_payload_bytes )
+          / (H[n+1] - H[n])
+     b1 = - SUM(n_payload_bytes) - b0
+
+   H[i] is the i-the element of the second row of matrix H. E.g. H[0] = x^(n-1)
+   The result has to be computed by Galois field arithmetics. See below.
+
+   The P-parity bytes of each column get reunited as LSB and MSB of two words.
+   word1 gets written to positions 1032 to 1074, word0 to 1075 to 1117.
+   The Q-parity bytes of each diagonal get reunited too. word1 goes to 1118
+   to 1143, word0 to 1144 to 1169.
+   >>> I do not read this swap of word1 and word0 from ECMA-130 Annex A.
+   >>> But the new output matches the old output only if it is done that way.
+   >>> See correctness reservation below.
+
+   Algebra on Galois fields is the same as on Rational Numbers.
+   But arithmetics is defined by operations on polynomials rather than the
+   usual integer arithmetics on binary numbers.
+   Addition and subtraction are identical with the binary exor operator.
+   Multiplication and division would demand polynomial division, e.g. by the
+   euclidian algorithm. The computing path over logarithms and powers follows
+   algebra and allows to reduce the arithmetic task to table lookups, additions
+   modulo 255, and exor operations. Note that the logarithms are natural
+   numbers, not polynomials. They get added or subtracted by the usual addition
+   (not by exor) and their polynomial power depends on their value modulo 255.
+
+   Needed are a logarithm table and a power table (or inverse logarithm table)
+   for Galois Field GF(2^8) which will serve to perform the peculiar
+   multiplication and division operation of Galois fields.
+
+   The power table is simply an enumeration of x^n accorting to
+   GF-multiplication. It also serves as second line of matrix H for the parity
+   equations:
+     Hp[i] = gfpow[25-i] , i out of {0,..,25}
+     Hq[i] = gfpow[44-i] , i out of {0,..,44}
+
+   The logarithm table is the inverse permutation of the power table.
+
+   Some simplifications apply to the implementation:
+   In the world of Galois fields there is no difference between - and +.
+   The term (H[n+1] - H[n]) is constant: 3.
+
+   -------------------------------------------------------------------------
+
+
+                                 Scrambling
+
+   ECMA-130 Annex B prescribes to exor the byte stream of an audio-sized sector
+   with a sequence of pseudo random bytes. It mentions polynomial x^15+x+1 and
+   a 15-bit register.
+   It shows a diagram of a Feedback Shift Register with 16 bit boxes, though.
+ 
+   Comparing this with explanations in 
+     http://www.newwaveinstruments.com/resources/articles/m_sequence_linear_feedback_shift_register_lfsr.htm
+   one can recognize the diagram as a Fibonacci Implementation. But there seems
+   really to be one bit box too many.
+
+   The difference of both lengths is expressed in function next_bit() by
+   the constants 0x3fff,0x4000 for 15 bit versus 0x7fff,0x8000 for 16 bits.
+   Comparing the output of both alternatives with the old scrambler output
+   lets 15 bit win for now.
+
+   So the prescription is to start with 15 bit value 1, to use the lowest bit
+   as output, to shift the bits down by one, to exor the output bit with the
+   next lowest bit, and to put that exor result into bit 14 of the register.
+
+   -------------------------------------------------------------------------
+
+
+                             Correctness Reservation
+
+   In both cases, parity and scrambling, the goal for now is to replicate the
+   output of the dismissed old lec.c by output which is based on published
+   specs and own implementation code. Whether they comply to ECMA-130 is a
+   different question which can only be answered by real test cases for
+   raw CD recording.
+
+   Of course this implementation will be corrected so that it really complies
+   to ECMA-130 as soon as evidence emerges that it does not yet.

+
+   Simplified data transmission for DVD. libburn via Linux USB is 30 % slower
+   than growisofs or cdrecord when transmitting 32 KB chunks.
+   With 64 KB chunks it is 20% faster than the competitors.
+   No heavy CPU load is visible but there might be subtle race conditions in
+   the USB driver which work better with shorter time gaps between WRITE
+   commands.
+
+   Insight: It is actually about the interference of track source reading
+            with SCSI writing via USB. growisofs reads with O_DIRECT into a
+            mmap()ed buffer. When doing the same, libburn with 32 KB chunks
+            reaches similar write speed.
+            On the other hand, 64 KB chunks are 20% faster than that and
+            are not improved by reading O_DIRECT.
+
+            O_DIRECT is a property of the input fd of struct burn_source.
+            It can only be done with properly aligned memory and with aligned
+            read size. Alignment size is file system system specific.
+            System call
+                mmap(NULL, (size_t) buffer_size, PROT_READ | PROT_WRITE,
+                     MAP_SHARED | MAP_ANONYMOUS, -1, (off_t) 0);
+            is supposed to allocate a properly aligned buffer.
+            64 KB is supposed to be a safe size.
+            Actually mmap() seems to be the main cause for a positive effect
+            of O_DIRECT.
+
+   This simplified transmission function did not bring visible benefit.
+   So for now it is not worth to teach it all applicable details of old
+   CD sector oriented transmission.
