/***************************************************************************
|
||||
* chm_lib.h - CHM archive manipulation routines *
|
||||
* ------------------- *
|
||||
* *
|
||||
* author: Jed Wing <jedwin@ugcs.caltech.edu> *
|
||||
* version: 0.3 *
|
||||
* notes: These routines are meant for the manipulation of microsoft *
|
||||
* .chm (compiled html help) files, but may likely be used *
|
||||
* for the manipulation of any ITSS archive, if ever ITSS *
|
||||
* archives are used for any other purpose. *
|
||||
* *
|
||||
* Note also that the section names are statically handled. *
|
||||
* To be entirely correct, the section names should be read *
|
||||
* from the section names meta-file, and then the various *
|
||||
* content sections and the "transforms" to apply to the data *
|
||||
* they contain should be inferred from the section name and *
|
||||
* the meta-files referenced using that name; however, all of *
|
||||
* the files I've been able to get my hands on appear to have *
|
||||
* only two sections: Uncompressed and MSCompressed. *
|
||||
* Additionally, the ITSS.DLL file included with Windows does *
|
||||
* not appear to handle any different transforms than the *
|
||||
* simple LZX-transform. Furthermore, the list of transforms *
|
||||
* to apply is broken, in that only half the required space *
|
||||
* is allocated for the list. (It appears as though the *
|
||||
* space is allocated for ASCII strings, but the strings are *
|
||||
* written as unicode. As a result, only the first half of *
|
||||
* the string appears.) So this is probably not too big of *
|
||||
* a deal, at least until CHM v4 (MS .lit files), which also *
|
||||
* incorporate encryption, of some description. *

/* Microsoft's LZX document and their implementation of the
|

* com.ms.util.cab Java package do not concur.
|
||||
*
|
||||
* In the LZX document, there is a table showing the correlation between
|
||||
* window size and the number of position slots. It states that the 1MB
|
||||
* window = 40 slots and the 2MB window = 42 slots. In the implementation,
|
||||
* 1MB = 42 slots, 2MB = 50 slots. The actual calculation is 'find the
|
||||
* first slot whose position base is equal to or more than the required
|
||||
* window size'. This would explain why other tables in the document refer
|
||||
* to 50 slots rather than 42.
|
||||
*
|
||||
* The constant NUM_PRIMARY_LENGTHS used in the decompression pseudocode
|
||||
* is not defined in the specification.
|
||||
*
|
||||
* The LZX document does not state the uncompressed block has an
|
||||
* uncompressed length field. Where does this length field come from, so
|
||||
* we can know how large the block is? The implementation has it as the 24
|
||||
* bits following after the 3 blocktype bits, before the alignment
|
||||
* padding.
|
||||
*
|
||||
* The LZX document states that aligned offset blocks have their aligned
|
||||
* offset huffman tree AFTER the main and length trees. The implementation
|
||||
* suggests that the aligned offset tree is BEFORE the main and length
|
||||
* trees.
|
||||
*
|
||||
* The LZX document decoding algorithm states that, in an aligned offset
|
||||
* block, if an extra_bits value is 1, 2 or 3, then that number of bits
|
||||
* should be read and the result added to the match offset. This is
|
||||
* correct for 1 and 2, but not 3, where just a huffman symbol (using the
|
||||
* aligned tree) should be read.
|
||||
*
|
||||
* Regarding the E8 preprocessing, the LZX document states 'No translation
|
||||
* may be performed on the last 6 bytes of the input block'. This is
|
||||
* correct. However, the pseudocode provided checks for the *E8 leader*
|
||||
* up to the last 6 bytes. If the leader appears between -10 and -7 bytes
|
||||
* from the end, this would cause the next four bytes to be modified, at
|
||||
* least one of which would be in the last 6 bytes, which is not allowed
|
||||
* according to the spec.
|
||||
*
|
||||
* The specification states that the huffman trees must always contain at
|
||||
* least one element. However, many CAB files contain blocks where the
|
||||
* length tree is completely empty (because there are no matches), and
|
||||
* this is expected to succeed.

|
||||
* every match.
|
||||
* - position_base is an index to the position slot bases
|

* - extra_bits states how many bits of offset-from-base data is needed.
