allow you to suppress the printing of unmarked packets.
This allows a user to mark the packets they wish to print and
print ONLY those packets by suppressing all other unmarked packets.
This may seem like a bit of a convoluted way of expressing things,
as usually the desired behavior would be to print the marked packets.
However, we do NOT print marked packets that are not displayed under
the current filter. To be maximally explicite I've expressed this
as suppressing unmarked frames.

get from calling "wtap_file()", so get rid of the call and the
(otherwise unused) variable to which its result gets assigned.
That lets us get rid of "wtap_file()" in Wiretap.
It also lets us get rid of the include of "zlib.h" in "file.h"; the
#defines of "file_open()", "filed_open()", and "file_close()" are also
unnecessary, so we get rid of those as well.
However, that means we need to include <zlib.h> in "gtk/main.c" and
"tethereal.c", so that the version number of libz is defined and can
show up in the version string.

a "Match Selected" on it - we can't do a "Match Selected" if the field
has no value (e.g., FT_NULL) and has a length of 0.
If we unselect the current packet, we don't have a protocol tree, so we
don't have a currently selected field - clear the "Match Selected" menu
item and the display in the status line of information about the
currently selected field.
Move the low-level statusbar manipulation into "gtk/main.c", in routines
whose API doesn't expose anything GTK+-ish.
"close_cap_file()" calls one of those routines to clear out the status
bar, so it doesn't need to take a pointer to the statusbar widget as an
argument.
"clear_tree_and_hex_views()" is purely a display-manipulating routine;
move it to "gtk/proto_draw.c".
Extract from "tree_view_unselect_row_cb()" an "unselect_field()" routine
to do all the work that needs to be done if the currently selected
protocol tree row is unselected, and call it if the currently selected
packet list row is unselected (if it's unselected, there *is* no
protocol tree, so no row can be selected), as well as from
"tree_view_unselect_row_cb()".
Before pushing a new field-description message onto the statusbar, pop
the old one off.
Get rid of an unused variable (set, but not used).

control whether we have a child process do the capturing; a user might
want the packet list to be updated as packets arrive but *not* want it
to scroll so that the most recently arrived packets are shown.
"prefs.capture_auto_scroll", not "auto_scroll_live", should control
whether we scroll a real-time-update capture's packet list;
"auto_scroll_live" isn't set by the capture dialog box,
"prefs_capture_auto_scroll" is.

as, on a large capture, it could take a significant amount of time.
Let the user stop the computation and, if they do, don't pop up the
statistics dialog box.
Create a new header file declaring the routines to create, update, and
destroy progress dialog boxes; those routines' APIs don't depend on
GTK+, but others declared in "ui_util.h" do, and we don't want to oblige
a source file to depend on GTK+ headers unless it uses a GTK+ API or an
API that depends on GTK+.

into epan/ftypes.
Re-write display filter routines using Lemon parser instead of yacc.
Besides using a different tool, the new grammar is much simpler, while
the display filter engine itself is more powerful and more easily extended.
Add dftest executable, to test display filter "bytecode" generation.
Add option to "configure" to build dftest or randpkt, both of which are not
built by default.
Implement Ed Warnicke's ideas about dranges in the new display filter and
ftype code.
Remove type FT_TEXT_ONLY in favor of FT_NONE, and have protocols registered
as FT_PROTOCOL. Thus, FT_NONE is used only for simple labels in the proto tree,
while FT_PROTOCOL is used for protocols. This was necessary for being
able to make byte slices (ranges) out of protocols, like "frame[0:3]"
Win32 Makefile.nmake's will be added tonight.

"color_t" structure to store color values (although currently it has all
the same fields that a GdkColor has; its currently advantage is that you
don't have to include any GTK/GDK stuff to declare it).
Add routines in the "gtk" directory to convert between "color_t" and
GdkColor values.
Define, in "prefs.h", all colors as "color_t" values rather than
GdkColor values. "prefs.h" now no longer needs to include <gtk/gtk.h>,
so don't include it.

can be put, and a pointer to the string for the column, which might or
might not point to that buffer.
Add a routine "col_set_str()", which sets the string for the column to
the string passed to it as an argument; it should only be handed a
static string (a string constant would be ideal). It doesn't do any
copying, so it's faster than "col_add_str()".
Make the routines that append to columns check whether the pointer to
the string for the column points to the buffer for the column and, if
not, copy the string for the column to the buffer for the column so that
you can append to it (so you can use "col_set_str()" and then use
"col_append_str()" or "col_append_fstr()").
Convert a bunch of "col_add_str()" calls that take a string constant as
an argument to "col_set_str()" calls.
Convert some "col_add_fstr()" calls that take a string constant as the
only argument - i.e., the format string doesn't have any "%" slots into
which to put strings for subsequent arguments to "col_set_str()" calls
(those calls are just like "col_add_str()" calls).
Replace an END_OF_FRAME reference in a tvbuffified dissector with a

"top-level" dissectors that libepan-users call, instead of dissect_packet().
The epan_dissect_t holds the tvbuff after dissection so that the tvbuff's
memory is not cleared until after the proto_tree is freed. (I might stuff
the proto_tree into the epan_dissect_t, too).
What remains of dissect_packet() in packet.c handles the tvbuff initialiation.
The real meat of dissect_packet() is now in dissect_frame(), in packet-frame.c
This means that "packet.c" is no longer a dissector, os it is no longer
passed to make-reg-dotc.
Once dissect_fddi() gets two wrapper functions (dissect_fddi_swapped()
and dissect_fddi_nonswapped()), the a dissector handoff routine could
be used instead of the switch statement in dissect_frame(). I'd register
a field like "wtap.encap"

may be redrawing a packet window that displays a frame other than the
current frame; give it arguments to specify the raw frame data and
"frame_data" structure for the frame.
This requires that each packet window have, associated with it, a
pointer to the "frame_data" structure; that replaces the "cap_len" and
"encoding" fields in a "PacketWinData" structure, as those are just
copies of fields from the frame's "frame_data" structure.
"packet_hex_print()" needn't be passed both the start and length values
from a "field_info" structure - just pass it a pointer to that
structure, or NULL for "no field is selected in the packet". It also
needn't, any longer, be passed the "cap_len" and "flags.encoding" fields
of a "frame_data" structure - just pass it a pointer to that structure.
In "redraw_hex_dump_all()", don't redraw the hex dump pane of the main
window if there is no current frame.

number of replies seen, keep the frame number of the first request seen
for that call and the first reply seen for that call. Use that to
determine whether a request or reply is a duplicate or not.
That means that we don't have to reset the table of RPC calls on a
rescan of the capture (which didn't even fix all the cases where we'd
have misreported the original call or reply as a duplicate due to having
seen it once on the initial pass through the file and once again when,
for example, the user clicked on the packet); doing so causes plenty of
other problems, so don't do that - and don't clear the "visited" flag on
frames on a rescan, either, as that's only done because we were clearing
out conversations and calling all protocols' "init" routines.
As a free bonus, this means that, for a reply, we know what frame the
request was in; put that information into the protocol tree for the
reply, snoop-style.
Make the table of RPC call information, and the routines that manipulate
it, static to "packet-rpc.c"; nobody outside "packet-rpc.c" uses them.

- add <stdarg.h> or <varargs.h> in snprintf.h
and remove those inclusions in the other #ifdef NEED_SNPRINTF_H codes
- remove the check of multiple inclusions in source (.c) code
(there is a bit loss of _cpp_ performance, but I prefer the gain of
code reading and maintenance; and nowadays, disk caches and VM are
correctly optimized ;-).
- protect all (well almost) header files against multiple inclusions
- add header (i.e. GPL license) in some include files
- reorganize a bit the way header files are included:
First:
#include <system_include_files>
#include <external_package_include_files (e.g. gtk, glib etc.)>
Then
#include "ethereal_include_files"
with the correct HAVE_XXX or NEED_XXX protections.
- add some HAVE_XXX checks before including some system header files
- add the same HAVE_XXX in wiretap as in ethereal
Please forgive me, if I break something (I've only compiled and regression
tested on Linux).

When capturing, report errors trying to create the output file
with "file_open_error_message()".
Make the "for_writing" argument to "file_open_error_message()" a
"gboolean", as it's either TRUE (if the file is being opened for
writing) or FALSE (if it's being opened for reading).
Report EISDIR as "XXX is a directory (folder), not a file.".
When checking whether an "open()" of a capture file succeeded, check
whether "open()" returns a negative number, not whether it returns 0.
In "wtap_open_offline()", if the file to be opened is a directory,
return EISDIR, not WTAP_ERR_NOT_REGULAR_FILE, so that the error message
can say "that's a directory, not a file".
If "wtap_open_offline()" returns WTAP_ERR_NOT_REGULAR_FILE, don't just
say the file is "invalid", say it's a "special file" or socket or some
other weird type of file.

a word to use in the progress dialog, and a flag indicating whether the
display filter is to be reevaluated or not, and:
have "colorize_packet()" call that routine with "Colorizing" and
FALSE as those arguments;
have the filtering code call that routine with "Filtering" and
TRUE as those arguments;
add an exported routine to call that routine with "Reprocessing"
and TRUE as those arguments, to use to re-generate the packet
list and to re-filter the packets if a protocol preference has
been changed.
Keep track of whether preferences are changed from their initial value
by a preferences file or a command-line option, or from their previous
value by the "Preferences" dialog box; have "prefs_apply_all()" only
call the "apply" callback for a module if they have.
Call "prefs_apply_all()" after the command-line arguments have been
parsed and after "OK" has been clicked in the "Preferences" dialog box,
to notify modules of preference changes if they've registered a callback
for that.
After "OK" has been clicked in the "Preferences" dialog box, if any
preferences have changed, call the reprocessing routine, as the summary
line for some frames and/or the current display filter's value when
applied to some frames may have changed as a result of a preference
change. Do the same after "OK" or "Apply" has been clicked in the
"Display Options" dialog box (as it controls a protocol preferences
item.

TRUE, meaning "don't delete this", and if its "stop this operation"
button gets clicked, don't have its handler delete the progress dialog;
instead, leave the deletion of the window up to the code using the

Make the "read file" operation destroy the dialog; all the other
operations already did so (as they just broke out of the loop doing the
operation, rather than returning).
Don't catch the "destroy" operation on the dialog box - its handler

freeze it before the operation.

shouldn't actually be deleted, FALSE if it should; they should not
return "void".)
