"snprintf()" returns a negative number, that's an error, and we assume
"errno" was set and return NULL, otherwise we cast its return value to
"size_t" and compare it with the size of the buffer we were given, and,
if it was bigger, we know that "snprintf()" didn't generate all the
characters it could be cause they wouldn't have fit, so we set "errno"
to ENOSPC and return NULL.

Use that routine rather than duplicating that code in the routines to

As that routine returns an error indication, have the code that calls

Move the definition of PF_DIR from <epan/epan.h> to <epan/filesystem.h>,

Add a routine to get the directory for "system files" such as

stuff currently being dissected is part of a packet included in an error
packet (e.g., an ICMP Unreachable packet). Have the TCP dissector not
bother doing reassembly if the TCP segment is part of an error packet,
rather than an actual TCP transmission; other dissectors might want to
treat those packets specially as well.
Add to the "tcpinfo" structure a flag indicating whether the URG flag
was set, rather than having the zero or non-zero value of the urgent
pointer indicate that. (Yes, at least as I read RFC 793, a zero urgent
pointer value isn't useful, as it means "the stuff before this segment
is urgent", but it's certainly possible to put onto the wire a TCP
segment with URG set and a zero urgent pointer.)
Don't dissect the TCP header by grabbing the entire header with
"tvb_memcpy()" and then pulling stuff out of it - extract stuff with
individual tvbuff calls, and put stuff into the protocol tree and the
Info column as we extract it, so that we can dissect a partial header.
This lets us, for example, get the source and destination ports from the
TCP header of the part of a TCP segment included in a minimum-length
ICMPv4 error packet.

reassembly was for an earlier message).

of protocol-id-plus-datum pairs, so that multiple protocols can attach
information to the same conversation.
Dissectors that attach information to a conversation should not assume
that if they find a conversation it has one of its data attached to it;
the conversation might've been created by another dissector.
svn path=/trunk/; revision=3901
that look up conversations in hash tables, unless they are arguments
that will be ignored; if they're not being ignored, then if the argument
is a null pointer you may get a crash if it's dereferenced, and if it's
not a null pointer you'll only get a match if the conversation has
whatever stuff the arguments points to as its first address or port.
If you match a conversation with a wildcarded address and/or port, and
the address and/or port matched a non-wildcarded search argument, and
the conversation is for a connection-oriented transport protocol, set
the wildcarded address and/or port for the conversation to the value
that matched it.
svn path=/trunk/; revision=3897
"try_conversation_dissector()" does - start with as exact matches as
possible, and then start doing wildcarding - so that it can find
conversations with wildcard addresses or ports even if both address and
port arguments are supplied to it.

"proto_item_set_text()" except that it appends the result of the
formatting to the item's current text, rather than replacing the item's
current text. Use it in the DNS dissector.
svn path=/trunk/; revision=3880
but, before you set the text, you throw an exception while putting stuff
under the subtree, you end up with an absolutely blank protocol tree
item, which is really gross. Instead of calling
"proto_tree_add_notext()", call "proto_tree_add_text()" with at least a
minimal label - yes, it does mean you do some work that will probably be
unnecessary, but, absent a scheme to arrange to do that work if it *is*
necessary (e.g., catching exceptions), the alternative is an ugly
protocol tree display.

directory in which global data files are stored. If an installed binary
is being run, that's the correct directory for them; if a build-tree
binary is being run, the "manuf" file will be there, and you can put
other data files there as well, if necessary.
Do the same with plugins, except that, if there's no
"plugins\\{version}" subdirectory of that directory, fall back on the
default installation directory, so you at least have a place where you
can put plugins for use by build-tree binaries. (Should we, instead,
have the Windows build procedure create a subdirectory of the "plugins"
source directory, with the plugin version number as its name, and copy
the plugins there, so you'd use the build-tree plugin binaries?)
Move "test_for_directory()" out of "util.c" and into
"epan/filesystem.c", with the other file system access portability
wrappers and convenience routines. Fix "util.h" not to declare it - or

"void *" that a dissector can set to point to such a structure; that
means that the stuff in the epan directory doesn't have to know anything
about the protocol-specific private data one dissector passes to
another, and that structure doesn't have to be changed if a dissector
wants to pass some new type of data to another dissector.

fractions-of-a-second (the units of which are either milliseconds or
microseconds, specified by a Boolean argument), and formats it into a
"DD days, HH hours, MM minutes, SS seconds" using a buffer supplied to
it. Have "time_secs_to_str()" and "time_msecs_to_str()" both use it.
Also, have it correctly handle the case of SS being > 0 but < 1 (which
"time_msecs_to_str()" didn't do).
Rename "rel_time_to_str()" to "rel_time_to_secs_str()", and add a
"rel_time_to_str()" routine that takes a "struct timeval" and hands its
seconds and microseconds values to "time_secs_to_str_buf()". Use
"rel_time_to_secs_str()" to format FT_RELATIVE_TIME values for now; we
might want to use "rel_time_to_str()" for them, though, or make it an
option (either a user option, or a per-field option, using the field
that also holds BASE_ values).

Defect number: 0011
Date: Jul 26 2001
Releases of Kazlib affected: 1.10 through 1.19
Status: Fixed in 1.20
Modules affected: except.c
Description: Members of the except_t structure needed to be declared
volatile because the structure is automatically allocated in the
except macro, modified after a setjmp() takes place, and accessed
after control returns via longjmp.
Solution: Upgrade to 1.20 or backpatch the fix.

requires it, for some annoying reason, even though it is, as far
as I know, GCC-based, and other GCC's don't require it);

reason, libpcap on MacOS X doesn't define it.
Clean up some whitespace in the help messages for the configure script.
