-=head1 NAME
-
-Mac::Finder::DSStore - Read and write Macintosh Finder DS_Store files
-
-=head1 DESCRIPTION
-
-C<Mac::Finder::DSStore> provides a handful of functions for reading and
-writing the desktop database files created by the Macintosh Finder.
-
-=head1 FUNCTIONS
-
-Many functions take a C<$store> argument which is the opened file as
-an instance of L<Mac::Finder::DSStore::BuddyAllocator>, or a C<$block>
-argument which is a specific block of the file as an instance of
-L<Mac::Finder::DSStore::BuddyAllocator::Block>.

-
-Retrieves the "superblock" pointed to by the C<DSDB> entry in the store's table
-of contents, and traverses the B-tree it points to, returning a list of
-the records in the tree. Alternately, you can supply a callback which will
-be invoked for each record, and C<getDSDBEntries> will return an empty list.

-
-C<$arrayref> must contain a correctly ordered list of

-=head1 NAME
-
-Mac::Finder::DSStore::BuddyAllocator - Allocate space within a file
-
-=head1 DESCRIPTION
-
-C<Mac::Finder::DSStore::BuddyAllocator>
-implements a buddy-allocation scheme within a file. It's used by
-C<Mac::Finder::DSStore> to read certain files created by the Macintosh
-Finder.
-
-The allocation methods do not perform any actual file I/O.
-The contents of allocated blocks are read and written by the caller using
-methods on C<BuddyAllocator::Block>.
-If the C<allocate> and C<free> methods are used,
-or if the C<toc> hash is modified,
-C<writeMetaData> must be called for the changes to be reflected in the file.
-

-=head1 BuddyAllocator::Block
-
-C<BuddyAllocator::Block> instances are returned by the
-C<blockByNumber> and C<getBlock> methods. They hold a pointer into
-the file and provide a handful of useful methods.
-
-(There are also two other classes, C<WriteBlock> and C<StringBlock>,
-which might be returned instead. Think of this as an interface rather
-than as a concrete class.)
-
-=head2 $block->read(length, [format])
-
-Reads C<length> bytes from the block (advancing the read pointer
-correspondingly). If C<format> is specified, the bytes read are
-unpacked using the format; otherwise a byte string is returned. 
-
-=head2 $block->length( )
-
-Returns the length (or size) of this block.
-
-=head2 $block->seek(position[, whence])
-
-Adjusts the read/write pointer within the block.
-
-=head2 $block->write(bytes)
-
-=head2 $block->write(format, items...)
-
-Writes data to the underlying file, at the position represented by this
-block. If multiple arguments are given, the first is a format string
-and the rest are the remaining arguments to C<pack>.
-
-=head2 $block->close([ zerofill ])
-
-This is generally a no-op, but if called on a writable block with
-C<zerofill = true>, then zeroes will be written from the current
-location to the end of the allocated block.
-
-=head2 $block->copyback( )
-
-Returns the block's contents as a string. For write blocks, this
-reads from the file. This is just here for debugging purposes and
-might change.

-=head1 DS_Store Format
-
-Some notes on the format of the Macintosh Finder's F<.DS_Store> files.
-
-=head1 OVERVIEW
-
-The Mac OS X Finder stores information about how it displays directories
-and files in files named F<.DS_Store> in each directory which it has touched.
-(This seems to be a departure from the pre-OSX method of storing all the
-information in one file at the root of each filesystem).
-The format is not documented by Apple.
-The information in this file is based on the reverse-engineering notes
-by Mark Mentovai published on the Mozilla wiki,
-and further investigation by me (Wim Lewis).
-
-=head1 FILE FORMAT
-
-The F<.DS_Store> file holds a series of records giving attributes of
-the files in the directory or of the directory itself (referred to as
-F<.>). These records are stored in a B-tree, and the pages of the
-B-tree are stored in the file by a "buddy allocator" along with a
-small amount of metadata. The allocator also provides a level of
-indirection, from small integers to file offsets, presumably allowing
-blocks to be relocated as they grow and shrink.
-
-The file is generally big-endian. Unless otherwise noted, an "integer"
-is a four-byte (32-bit) big-endian number, probably unsigned (but I'm
-not always sure about that).
-
-=head2 Records
-
-A record has the following format:
-
-=over
-
-=item *
-
-Filename length, in characters, as an integer. (4 bytes)
-
-=item *
-
-Filename, in big-endian UTF-16. Presumably with the same Unicode
-composition rules as the HFS+ filesystem. (2 * length bytes)
-
-=item *
-
-Structure id or type, a FourCharCode indicating what property of the
-file this entry describes. (4 bytes)
-
-=item *
-
-Data type (4 bytes), indicating what kind of data field follows:
-
-=over
-
-=item C<'long'>
-
-An integer (4 bytes)
-
-=item C<'shor'>
-
-A short integer? Still stored as four bytes, but the first two are
-always zero.
-
-=item C<'bool'>
-
-A boolean value, stored as one byte.
-
-=item C<'blob'>
-
-An arbitrary block of bytes, stored as an integer followed by that
-many bytes of data.
-
-=item C<'type'>
-
-Four bytes, containing a FourCharCode.
-
-=item C<'ustr'>
-
-A Unicode text string, stored as an integer character count followed 
-by 2*count bytes of data in UTF-16.
-
-=item C<'comp'>
-
-An eight-byte (64-bit) integer.
-(I don't know why the abbreviation "comp" was chosen for this.)
-
-=item C<'dutc'>
-
-A datestamp, represented as an 8-byte integer count of the number
-of (1/65536)-second intervals since the Mac epoch in 1904. Given
-the name, this probably corresponds to the C<UTCDateTime> structure.
-
-=back
-
-=back
-
-A given structure id/type always seems to have the same type of data
-associated with it, and any structure id appears at most once per
-filename. Some only appear on files, and some only appear on
-directories (including the filename F<.>).
-
-Information about a directory (its Finder window view settings, for
-example) is usually held in its parent directory's store file, unless
-the directory is at the root of its volume, in which case it's held
-in the directory itself with the filename F<.>.
-
-I've encountered the following record types:
-
-=over
-
-=item C<'BKGD'>
-
-12-byte C<blob>, directories only. Indicates the background of the
-Finder window viewing this directory (in icon mode). The format
-depends on the kind of background:
-
-=over
-
-=item Default background
-
-FourCharCode C<DefB>, followed by eight unknown bytes, probably garbage.
-
-=item Solid color
-
-FourCharCode C<ClrB>, followed by an RGB value in six bytes, followed by two unknown bytes.
-
-=item Picture
-
-FourCharCode C<PctB>, followed by the the length of the blob
-stored in the C<'pict'> record, followed by four unknown bytes.
-The C<'pict'> record points to the actual background image.
-
-=back
-
-=item C<'ICVO'>
-
-C<bool>, directories only. Unknown meaning. Always seems to be 1, so
-presumably 0 is the default value.
-
-=item C<'Iloc'>
-
-16-byte C<blob>, attached to files and directories. 
-The file's icon location. Two 4-byte values representing the
-horizontal and vertical positions of the icon's center (not
-top-left). (Then, 6 bytes 0xff and 2 bytes 0?) For the purposes of the
-center, the icon only is taken into account, not any label. The icon's
-size comes from the icvo blob.
-
-=item C<'LSVO'>
-
-C<bool>, attached to directories. Purpose unknown.
-
-=item C<'bwsp'>
-
-A C<blob> containing a binary plist. This contains the size
-and layout of the window (including whether optional parts like
-the sidebar or path bar are visible).
-This appeared in Snow Leopard (10.6).
-
-The plist contains the keys C<WindowBounds> (a string in the same
-format in which AppKit saves window frames); C<SidebarWidth> (a
-float), and booleans C<ShowSidebar>, C<ShowToolbar>, C<ShowStatusBar>,
-and C<ShowPathbar>.  Sometimes contains C<ViewStyle> (a string),
-C<TargetURL> (a string), and C<TargetPath> (an array of strings).
-
-=item C<'cmmt'>
-
-C<ustr>, containing a file's "Spotlight Comments".
-(The comment is also stored in the C<com.apple.metadata:kMDItemFinderComment>
-xattr; this copy may be historical.)
-
-=item C<'dilc'>
-
-32-byte C<blob>, attached to files and directories.
-Unknown, may indicate the icon location
-when files are displayed on the desktop.
-
-=item C<'dscl'>
-
-C<bool>, attached to subdirectories. Indicates that the
-subdirectory is open (disclosed) in list view.
-
-=item C<'extn'>
-
-C<ustr>. Often contains the file extension of the file, but sometimes
-contains a different extension.
-Purpose unknown.
-
-=item C<'fwi0'>
-
-16-byte C<blob>, directories only.
-Finder window information.
-The data is first four two-byte values representing the top, left,
-bottom, and right edges of the rect defining the content area of the
-window. The next four bytes represent the view of the window: C<icnv>
-is icon view, other values are C<clmv> and C<Nlsv>.
-The next four bytes are unknown, and are either zeroes or
-C<00 01 00 00>.
-
-On Leopard (10.5), the view-type information seems to be ignored,
-but see C<vstl>. On Snow Leopard (10.6), some more of this record's
-function seems to have been taken over by the plist records C<bwsp>,
-C<lsvp>, and and C<lsvP>.
-
-=item C<'fwsw'>
-
-C<long>, directories only. Finder window sidebar width, in
-pixels/points. Zero if collapsed.
-
-=item C<'fwvh'>
-
-C<shor>, directories only.
-Finder window vertical height. If present, it overrides the height
-defined by the rect in fwi0. The Finder seems to create these (at
-least on 10.4) even though it will do the right thing for window
-height with only an fwi0 around, perhaps this is because the stored
-height is weird when accounting for toolbars and status bars. 
-
-=item C<'GRP0'>
-
-C<ustr>. Unknown; I've only seen this once.
-
-=item C<'icgo'>
-
-8-byte C<blob>, directories (and files?).
-Unknown. Probably two integers, and often the value C<00 00 00 00 00
-00 00 04>.
-
-=item C<'icsp'>
-
-8-byte C<blob>, directories only.
-Unknown, usually all but the last two bytes are zeroes.
-
-=item C<'icvo'>
-
-18- or 26-byte C<blob>, directories only.
-Icon view options. There seem to be two formats for this blob.
-
-If the first 4 bytes are "icvo", then 8 unknown bytes (flags?), then 2 bytes
-corresponding to the selected icon view size, then 4 unknown bytes
-C<6e 6f 6e 65> (the text "none", guess that this is the "keep
-arranged by" setting?).
-
-If the first 4 bytes are "icv4", then:
-two bytes indicating the icon size in pixels, typically 48;
-a 4CC indicating the "keep arranged by" setting
-(or C<none> for none or C<grid> for align to grid);
-another 4CC, either C<botm> or C<rght>,  indicating the label position I<w.r.t.> the icon;
-and then 12 unknown bytes (flags?).
-
-Of the flag bytes, the low-order bit of the second byte is 1 if "Show
-item info" is checked, and the low-order bit of the 12th (last) byte
-is 1 if the "Show icon preview" checkbox is checked. The tenth byte
-usually has the value 4, and the remainder are zero.
-
-=item C<'icvp'>
-
-A C<blob> containing a plist, giving settings for the icon view.
-Appeared in Snow Leopard (10.6), probably supplanting C<'icvo'>.
-
-The plist holds a dictionary with several key-value pairs:
-booleans C<showIconPreview>, C<showItemInfo>, and C<labelOnBottom>;
-numbers C<scrollPositionX>, C<scrollPositionY>, C<gridOffsetX>, C<gridOffsetY>,
-C<textSize>, C<iconSize>, C<gridSpacing>, and C<viewOptionsVersion>;
-string C<arrangeBy>.
-
-The value of the C<backgroundType> key (an integer) presumably controls
-the presence of further optional keys such as C<backgroundColorRed>/C<backgroundColorGreen>/C<backgroundColorBlue>.
-
-=item C<'icvt'>
-
-C<shor>, directories only.
-Icon view text label (filename) size, in points.
-
-=item C<'info'>
-
-40- or 48-byte C<blob>, attached to directories and files.
-Unknown. The first 8 bytes look like a timestamp as in C<dutc>.
-
-=item C<'logS'> or C<'lg1S'>
-
-C<comp>, directories only. Appears to contain the logical size in
-bytes of the directory's contents, perhaps as a cache to speed up
-display in the Finder.
-I think that C<'logS'> appeared in 10.7 and was
-supplanted by C<'lg1S'> in 10.8. See also C<'ph1S'>.
-
-=item C<'lssp'>
-
-8-byte C<blob>, directories only.
-Unknown. Possibly the scroll position in list view mode?
-
-=item C<'lsvo'>
-
-76-byte C<blob>, directories only.
-List view options. Seems to contain the columns displayed in list
-view, their widths, and their sort ordering if any. Presumably
-supplanted by C<lsvp> and/or C<lsvP>.
-
-These list view settings are shared between list view and the list
-portion of coverflow view.
-
-=item C<'lsvt'>
-
-C<shor>, directories only.
-List view text (filename) size, in points.
-
-=item C<'lsvp'>
-
-A C<blob> containing a binary plist. List view settings, perhaps
-supplanting the C<'lsvo'> record. Appeared in Snow Leopard (10.6).
-
-The plist contains boolean values for the keys C<showIconPreview>,
-C<useRelativeDates>, and C<calculateAllSizes>; numbers for
-C<scrollPositionX>, C<scrollPositionY>, C<textSize>, C<iconSize>, and
-C<viewOptionsVersion> (typically 1); and a string, C<sortColumn>.
-
-There is also a C<columns> key containing the set of columns, their widths,
-visibility, column ordering, sort ordering.
-The only difference between C<lsvp> and C<lsvP> appears to be the
-format of the columns specification: an array or a dictionary.
-
-=item C<'lsvP'>
-
-A C<blob> containing a binary plist.
-Often occurs with C<lsvp>, but may have appeared in 10.7 or 10.8.
-
-=item C<'modD'> and C<'moDD'>
-
-C<dutc> timestamps; directories only.
-One or both may appear.
-Typically the same as the directory's modification date.
-Unknown purpose; appeared in 10.7 or 10.8.
-Possibly used to detect when C<logS> needs to be recalculated?
-
-=item C<'phyS'> or C<'ph1S'>
-
-C<comp>, directories only. This number is always a multiple of
-8192 and slightly larger than C<'logS'> / C<'lg1S'>, which always
-seems to be present if this is (though the reverse is not always true).
-Presumably it is the corresponding physical size (an integer number of
-8k-byte disk blocks). 
-
-=item C<'pict'>
-
-Variable-length C<blob>, directories only.
-Despite the name, this contains not a PICT image but an Alias record
-(see I<Inside Macintosh: Files>) which resolves to the file containing
-the actual background image. See also C<'BKGD'>.
-
-=item C<'vSrn'>
-
-C<long>, attached to directories.
-Always appears to contain the value 1.
-Appeared in 10.7 or 10.8.
-
-=item C<'vstl'>
-
-C<type>, directories only. Indicates the style of the view
-(one of C<icnv>, C<clmv>, C<Nlsv>, or C<Flwv>,
-indicating respectively: icon view, column/browser view, list view, and coverflow view)
-selected by the Finder's "Always open in icon [or other style] view"
-checkbox.
-This appears to be a new addition to the Leopard (10.5) Finder.
-
-=back
-
-=head2 B-Tree
-
-The records are stored in a B-tree structure. The B-tree consists of a
-small master block containing a few statistics and a pointer to the
-root node; one or more leaf (external) nodes; and zero or more
-non-leaf (internal) nodes.
-
-The header block is pointed to by the C<DSDB> entry in the buddy
-allocator's directory. It is 20 bytes long and contains five integers:
-
-=over
-
-=item
-
-The block number of the root node of the B-tree
-
-=item
-
-The number of levels of internal nodes (tree height minus one --- that
-is, for a tree containing only a single, leaf, node this will be zero)
-
-=item
-
-The number of records in the tree
-
-=item
-
-The number of nodes in the tree (tree nodes, not including this header
-block)
-
-=item
-
-Always 0x1000, probably the tree node page size 
-
-=back
-
-Individual nodes are either leaf nodes containing a bunch of records,
-or non-leaf (internal) nodes containing N records and N+1 pointers to
-child nodes.
-
-Each node starts with two integers, C<P> and C<count>. If C<P> is 0,
-then this is a leaf node and C<count> is immediately followed by that
-many records. If C<P> is nonzero, then this is an internal node, and
-C<count> is followed by the block number of the leftmost child, then a
-record, then another block number, I<etc.>, for a total of C<count>
-child pointers and C<count> records. C<P> is itself the rightmost
-child pointer, that is, it is logically at the end of the node.
-
-This relies on 0 not being a valid value for a block number. As far as
-I can tell, 0 is a valid value for a block number but it always holds
-the block containing the buddy allocator's internal information,
-presumably because that block is allocated first.
-
-The ordering of records within the B-tree is by case-insensitive
-comparison of their filenames, secondarily sorted on the structure
-ID (record type) field. My guess is that the string comparison follows
-the same rules as HFS+ described in Apple's TN1150.
-
-=head2 Buddy Allocator
-
-B-tree pages and other info are stored in blocks managed by a buddy
-allocator. The allocator maintains a list of the offsets and sizes of
-blocks (indexed by small integers) and a freelist. 
-The allocator also stores a small amount of metadata, including a
-directory or table of contents which maps short strings to block
-numbers. The only entry in that table of contents maps the string
-C<DSDB> ("desktop services database"?) to the B-tree's master block.
-
-The buddy allocator is in charge of all but the first 36 bytes of
-the file, and manages a notional 2GB address space, although the file is
-of course truncated to the last allocated block. All its offsets are
-relative to the fourth byte of the file. Another way to describe this
-is that the file consists of a four-byte header (always C<00 00 00
-01>) followed by a 2GB buddy-allocated area, the first 32-byte block
-of which is allocated but does not appear on the buddy allocator's
-allocation list.
-
-The 32-byte header has the following fields:
-
-=over
-
-=item *
-
-Magic number C<Bud1> (C<42 75 64 31>)
-
-=item *
-
-Offset to the allocator's bookkeeping information block
-
-=item *
-
-Size of the allocator's bookkeeping information block
-
-=item *
-
-A second copy of the offset; the Finder will refuse to read the file
-if this does not match the first copy. Perhaps this is a safeguard
-against corruption from an interrupted write transaction.
-
-=item *
-
-Sixteen bytes of unknown purpose.
-These might simply be the unused space at the end of the block,
-since
-the minimum allocation size is 32 bytes, as will be seen later.
-
-=back
-
-The offset and size indicate where to find the block containing the
-rest of the buddy allocator's state. That block has the following
-fields:
-
-=over
-
-=item Block count
-
-Integer. The number of blocks in the allocated-blocks list.
-
-=item Unknown
-
-Four unknown bytes. Appear to always be 0.
-
-=item Block addresses
-
-Array of integers. There are I<block count> block addresses here, with
-unassigned block numbers represented by zeroes. This is followed by
-enough zeroes to round the section up to the next multiple of 256
-entries (1024 bytes).
-
-=item Directory count
-
-Integer, indicates the number of directory entries.
-
-=item Directory entries
-
-Each consists of a 1-byte count, followed by that many bytes of name
-(in ASCII or perhaps some 1-byte superset such as MacRoman), followed
-by a 4-byte integer containing the entry's block number.
-
-=item Free lists
-
-There are 32 freelists, one for each power of two from 2^0 to
-2^31. Each freelist has a count followed by that many offsets.
-
-=back
-
-There are three different ways to refer to a given block. Most of the
-file uses what I call block numbers or block IDs, which are indexes
-into the C<block address> table. Block ID 0 always seems to refer to
-the buddy allocator's metadata block itself.
-
-The entries in the block address table are what I call block addresses.
-Each address is a packed offset+size. The least-significant 5 bits of
-the number indicate the block's size, as a power of 2 (from 2^5 to
-2^31). If those bits are masked off, the result is the starting offset
-of the block (keeping in mind the 4-byte fudge factor). Since the
-lower 5 bits are unusable to store an offset, blocks must be allocated
-on 32-byte boundaries, and as a side effect the minimum block size is
-32 bytes
-(in which case the least significant 5 bits are equal to C<0x05>).
-
-The free lists contain actual block offsets, not "addresses". The
-size of the referenced blocks is implied by which freelist the block
-is in; a free block in freelist N is 2^N bytes long.
-
-Although the header block is not explicitly allocated, the allocator
-behaves as if it is; other blocks are split in order to accommodate it
-in the buddy scheme, and its buddy block (at 0x20) is either on the
-freelist or allocated. (Usually it holds the B-tree's master block.)
-
-Other than the 4-byte prefix and the 32-byte header block, every byte
-in the file is either in a block on the allocated blocks list, or is in a
-block on one of the free lists.
