Lex code is often hard for humans to understand... neither of the error conditions found would be happening...
One was marked as error because coverity does not understand that yyterminate() breaks execution.
The other marked as an error because coverity is not able to figure out that the error appears in an actions against two different rules that will not ever match toghether.

(still untested, and probably broken)

make sure isXxx() functions do not trigger an error, we want them to return not to pop the stack back to the lua caller.

- add doComments
- fix an error in DissectorTable_remove
- reorganize DissectorTable_try
- elua.h
squelch some warnings
- Makefile.nmake
- replace the $^ macro with the targets (i.e. do what nmake was supposed to do)
- move the doc target into the conditional part
svn path=/trunk/; revision=17406
- also supress Address__ge and Address_gt because re-reading the ref manual I noticed that they are suplerfluous (Lua assumes that a > b is equivalent to b < a, which in most cases (as this) it does)
- have elua_makedoc.pl hanlde docomments in more than one line and after the line where the entity s defined.
svn path=/trunk/; revision=17382
- Changed some Macros
- Have dump:close NULLyfing the boxed object so that no futher operations are performed on a dumper once is closed.
- Check if elua_register.h has changed and avoid overwriting it if it hasn't changed to avoid unnecessary compilations.
svn path=/trunk/; revision=17374

- start of elua_makedoc.pl that should generate the Reference Manual from the code.

- columns live for less than a packet's time, use ep_alloc not g_malloc
- tvbranges are ephemeral too
doc/ is to remain as a placeholder for upcoming docs.
lualib/ is to be deleted (if needed it should go in trunk) but it appears that once I added if I do not check it in I cannot delete it.

* save one lua table lookup by using a reference to the dissectors table instead of looking for it by name
* set data_hanlde's value to avoid a crash while invoking it.
* make the TvbRange of Tree:add_item really optional.

* ProtoTree_add_item_any() changed to use TvbRanges, a more handy way to give it optional arguments
* lua_tvb.c
* get ByteArray up and running
* create TvbRange class and use it to access the tvb (this class takes care of checking bounds so that exceptions are not thrown)

This patch adds support for dissection of the DCC packet as defined in
CableLab's (http://www.cablelabs.com/) DOCSIS Radio Frequency Interface
(RFI) specification. The latest version of this specification is currently
available at
http://www.cablemodem.com/specifications/specifications20.html . Packet
formats for DCC are defined in sections 8.3.20 (DCC-REQ), 8.3.21
(DCC-RSP), and 8.3.22 (DCC-ACK) of the RFI specifications (referencing
version CM-SP-RFIv2.0-I10-051209). In addition, this patch adds support
for the DCD packet as defined in the DOCSIS Set-Top Gateway (DSG)
Specification. The latest version of this specification is currently
available at http://www.cablemodem.com/specifications/gateway.html . The
format of the DCD packet is defined in section 5.3.1 of the DSG
specification (referencing version CM-SP-DSG-I06-051209).

* SubTreeType (ett) was renamed as SubTree
* lua_tap.c
- change the way the taps register (still to be finished so I won't comment)
* lua_tree.c
* SubTree(ett) moved here, now it autoregisters all subtrees created at once. The user neither does need to create a SubTreeArray(eliminated) anymore nor to register it.
* lua_proto.c
* SubTree moved out from here its "global" variables are used by lua_tree.c .
* SubTreeArray was eliminated (now ett's "autoregister")
* Created usertypes for
- Pref a preference
- Prefs all preferences of one protocol
So far they are transparent to the user.
* Proto has become a pseudo-table instead of a method based (registration in nicer)
* packet-lua.c
* runtime errors go where they are meant to:
- errors in dissector code go to the tree (a-la malformed)
- errors in registration/handoff/init use reporte_failure()
* no more Lua code to be compiled at runtime

* ValueString makes no sense, get rid of it we'll use Lua's associative arrays instead
* lua_tvb.c
* while creating a tvb from a ByteArray copy the ByteArray's data and set the tvb's free_cb
* check bounds before calling tvb_*() to avoid a longjmp breaking Lua
* do not leak the string in Tvb_tostring()
* new Tvb:get_ipv4() call
* new Tvb:get_eth() call
* packet-lua.[ch]

This is an interface to the Lua programming language.
http://www.lua.org
I've already wrote a simple dissector that calls another dissectors.
soon It will be able to register a tap and do something more.
I did not checkin changes to the Makefiles so in order to use it you must change the makefiles.
Other than that to get it to work you need to download lua-5.0.2.tar.gz into the plugin directory, uncompress it, cd to it and call make.
the interface is buggy and far from finished, time will help on this.

include fails as we don't do -Iwiretap.
If we have it, include <sys/stat.h> in epan/filesystem.c - we need it
for stat() and the macros and structures it uses.
svn path=/trunk/; revision=16410
to do this, I've added file_util.h to wiretap (would file_compat.h be a better name?), and provide compat_macros like eth_open() instead of open(). While at it, move other file related things there, like #include <io.h>, definition of O_BINARY and alike, so it's all in one place.
deleted related things from config.h.win32
As of these massive changes, I'm almost certain that this will break the Unix build. I'll keep an eye on the buildbot so hopefully everything is working again soon.

print register numbers as unsigned (they're guint32);
when printing a PUT_FVALUE instruction, show the value as well
as the type of the value.
That requires that a bunch of types get to_repr methods; add them for
PCRE (FTREPR_DFILTER-only - show the regular expression as text),
tvbuffs (FTREPR_DFILTER_only - show the data as a hex string), integral
types, string types other than FT_STRING, and FT_IPv6.
That means we can use fvalue_to_string_repr() for FT_IPXNET and FT_IPv6
in proto_construct_dfilter_string(), and that we don't need to handle
integer and floating types specially in MATE.
Fix some problems with the PCRE execution code for tvbuff types.

and that extract IPv6 addresses into a "struct e_in6_addr", with
tvb_get_ipv4() and tvb_get_ipv6() calls - except for some that we
remove, by using proto_tree_add_item(), rather than replacing.
Have epan/tvbuff.h include epan/ipv6-utils.h, to define "struct
e_in6_addr" (not necessary to declare the tvbuff routines, but including
it there means "struct e_in6_addr" is guaranteed to be defined before
those declarations, so we don't get compiler complaints if we define it
*after* those declarations).

I've done more than a day to change the timestamp resolution from microseconds to nanoseconds. As I really don't want to loose those changes, I'm going to check in the changes I've done so far. Hopefully someone else will give me a helping hand with the things left ...
What's done: I've changed the timestamp resolution from usec to nsec in almost any place in the sources. I've changed parts of the implementation in nstime.s/.h and a lot of places elsewhere.
As I don't understand the editcap source (well, I'm maybe just too tired right now), hopefully someone else might be able to fix this soon.
Doing all those changes, we get native nanosecond timestamp resolution in Ethereal. After fixing all the remaining issues, I'll take a look how to display this in a convenient way...
As I've also changed the wiretap timestamp resolution from usec to nsec we might want to change the wiretap version number...

"conversation_add_proto_data()" is supposed to be a protocol ID, as
returned by "proto_register_protocol()". In addition, there are two
different types of protocol data being attached to a conversation; use
different protocol IDs for them, so we don't misinterpret an
"iap_conversation_t" as a "lmp_conversation_t" or vice versa.
