update old tags.
Modified cdrom.c to expose metadata read/write functions, and changed
chdman to use them. Also changed chdman to parse old-style metadata and
convert it to new-style metadata since we're going to need to re-do this
anyway and the two won't hash to the same value.
Added completely untested support for the ident metadata to the hard
disk creation path. If a filename is provided immediately after the
source filename, it is taken as an ident file and processed for CHS
data and added. Other metadata types can be added afterwards via
-addmeta.
Updated CHD format to version 4. Checksums are now computed and
stored separately for raw data and metadata, and metadata is now
checksummed by default.
We will need to go through all existing CHDs, run a chdman -update
on them, and update the SHA1s stored in the drivers to accommodate
this (MD5s should be removed).
Updated chdman to support a generic metadata addition system:
chdman -addmeta <chdfile> <tag> [<index>] <sourcefile>
The <sourcefile> is examined and if it appears to be strictly text,
any EOFs and trailing EOLs are stripped, and the result is NULL-
terminated to match the behavior of existing metadata.
Updated chdman to report and fix errors in the raw and metadata
SHA1s.
Changed the CHD verify interfaces to pass back a structure containing
all the necessary data for verification and fixing.
compilation:
- new option CPP_COMPILE to trigger this (off by default)
- split CFLAGS into common, C-only, and C++-only flags
- when enabled, CPP_COMPILE causes 'pp' to be appended to
the target name
NOTE THAT THE SYSTEM CANNOT ACTUALLY BE COMPILED THIS WAY
YET. IT IS JUST AN EXPERIMENT.
Modified lib.mak to always build zlib/expat as C regardless
of CPP_COMPILE.
Modified windows.mak to fix warnings with MAXOPT=1, and to
leverage the new CFLAGs definitions.
Modified vconv.c to do appropriate conversions for new C++
options.
Updated sources so that libutil, libocore (Windows), and
libosd (Windows) can be cleanly compiled as C or C++. This
was mostly adding some casts against void *.
Fixed a few more general obvious problems at random
locations in the source:
- device->class is now device->devclass
- TYPES_COMPATIBLE uses typeid() when compiled for C++
- some functions with reserved names ('xor' in particular)
were renamed
- nested enums and structs were pulled out into separate
definitions (under C++ these would need to be scoped to
be referenced)
- TOKEN_VALUE cannot use .field=x initialization in C++ :(
streams and a delta-RLE pre-encoding. Added optimized
case for the Y/Cb/Y/Cr video encoding case. Cleaned up
the code.
Updated avcomp.c to use the new huffman.c functions.
Reworked configuration options to allow for both input
and output of naturally aligned data streams. Updated
chdman and laserdsc to use the new interfaces. New
compression gives an additional 3-7% over previous
attempt and compresses the dummy CHDs down significantly.
tool which walks through either an AVI or CHD capture from a
laserdisc and ensures that there are no anomalies lurking in
the VBI data.
Added new option to chdman, where if you use -createav with
a special filename (either 2:2 or 3:2) it will create a fake
laserdisc files with the equivalent cadence. This can be used
for testing until full captures are available. Most games used
2:2 apart from Dragon's Lair and Space Ace, which were 3:2.
Note that even though these files are essentially blank, they
are Huffman-compressed, meaning that the maximum compression
ratio you will get is 8:1, so they still end up ~5GB.
Moved error strings from chdman.c to chd.c, where they can be
fetched from any caller via the new chd_error_string()
function.
Updated vbiparse to improve Manchester code decoding. It now
assigns a confidence level per bit based on how solid the
data is. Also added a new function vbi_parse_all which parses
the white flag and all three lines of metadata from a
laserdisc frame. It then compares line 17 and 18 against each
other and selects the most likely candidate based on per-bit
confidence and other factors.
Added frame number display to laserdsc.c. It is off by
default, though most players can be configured to turn it on
(not sure if any actually do). It can be manually toggled via
the backslash key during playback.
now simply requires an AVI file input.
Relaxed VBI Manchester code clocking to allow for a little bit
of wiggle when finding the clock.
Changed laserdisc support to parse white flags and other data
from the VBI data directly, rather than relying on the textual
metadata. Expanded video frame cache to 3. Changed the way
frames are assembled to decrease the likelihood of getting an
interlaced weave. Fixed sound creation so that it is done at
reset time instead of device start, when the sound devices aren't
yet live.
Fixed bug in winwork that caused the creation of single work
items to return NULL, and thus lead to massive memory leaks when
using A/V CHDs.
Subject: [patch] Conditional code cleanup resubmit
Hi mamedev,
This is a resubmit of a previous patch. The earlier version would not
compile with 32-bit MSVC, due to the fact that its linker required
external dependencies in dead code to be met before dead code
elimination was done, causing linker errors. The proper fix for this
would be to add the necessary dependencies, so I instead simply left
the conditional code in place in winalloc.c and chd.c.

----
Conditionally compiled code tends to bitrot, so MAME should try to
avoid it as much as possible. I sent a patch six months ago to
eliminate conditional code associated with logging, here's another
patch that does more of this. Some notes:
1. drc_ops.c: I couldn't find a LOG_CODE anywhere, so I used if (0).
2. romload.c: I converted all the users of debugload to use
LOG((...)) instead, following the traditional conditional logging
pattern.
3. windows/sound.c: I eliminated the separate sound log and directed
the few outputs to the error log.

Subject: [patch] Fix some comments
Hi mamedev,
The following patch updates the initialization comments at the top of
mame.c and corrects/adds a few filename declarations at the top of a
handful of files.
