The former, which used to be called by "load_cap_file()", now just opens
the file and, if the open succeeds, closes any capture file we
previously had open, reinitializes any protocols that need
reinitialization, and saves information about the new capture file in
the "capture_file" structure to which it was passed a pointer. The
latter reads the file already opened by "read_cap_file()".
For "File/Open", call "open_cap_file()" before dismissing the file
selection box; if it fails, "open_cap_file()" will have popped up a
message box complaining about it - just return, leaving the file
selection box open so the user can, after dismissing the message box,
either try again with a different file name, or dismiss the file
selection box. (Other file selection boxes should be made to work the
same way.) If "open_cap_file()" succeeds, dismiss the file selection
box, and read the capture file in.

the "Open File" dialog box (the "Open File" dialog box equivalent of the
"-R" flag). Have "load_cap_file()" take the filter expression as an
argument, and make the global "rfilter" into a member of a
"capture_file" structure.
When reading a temporary capture file after a live capture, don't apply
any filter.
Move the code that pops up error boxes on file opens when reading a
capture file back to "load_cap_file()"; it also pops up error boxes if
the filter expression can't be parsed.
Don't enable "File/Save" or "File/Save As..." if an attempt to read a
capture file fails - if there was already an open capture file, it was
closed by "load_cap_file()", so we no longer have an open file to save.

N^2 in the ultimate size of the list (as "g_list_append()" is linear in
the size of the list, at least when used in the way the GLib
documentation says to use it); instead, maintain our own linked list of
"frame_data" structures for all packets read, including a pointer to the
last element.
"gtk_clist_set_row_data()" is linear in the row number, so if it's used
to attach a pointer to the "frame_data" structure for a packet to the
packet list GtkClist row for each packet, that's also N^2 in the number
of packets in that packet list; instead, store the row number in the
"frame_data" structure, and find the packet for a given row by scanning
the list for it (we were already scanning the list linearly to find that
packet's index in the list of all packets; that's only done when a
packet's selected, so it's not *too* bad, but it might be nice to avoid
having to do that scan).

try as I might, I couldn't get gtk_timeout_add to work. I read all the docs,

I also modified file_progress_cb to use it's local copy of cf rather
than the global copy.

double-click on a packet, it'll select that packet without necessarily

wiretap support for RADCOM Ltd.'s WAN/LAN analyzers (see
http://www.radcom-inc.com/
). Note: as I remember, IEEE 802.2/ISO 8022 LLC has somewhat of an SDLC
flavor to it, just as I think LAP, LAPB, LAPD, and so on do, so we may
be able to combine some of the LLC dissection and the LAPB dissection
into common code that could, conceivably be used for other SDLC-flavored
protocols.
Make "S" a mnemonic for "Summary" in the "Tools" menu.
Move the routine, used for the "Tools/Summary" display, that turns a

files from a RADCOM analyzer.
Have "Tools/Summary" display the snapshot length for the capture.

- read only the real number of packets that have been written
by the child process. That's avoid incomplete packet read.

"capture_file" structure, make a "select_packet()" routine to parallel
"unselect_packet()", and have "unselect_packet()" free the protocol tree
that the "protocol_tree" member of the "capture_file" passed to it
points to.
It should now be impossible to do a "Print Packet" operation if no
packet has been selected, so remove the check for that (we'll probably
just blow up if it happens; if it does, that means we probably forgot to
gray out "/File/Print Packet" somewhere, so we should fix that).

you have a capture.
Leave the job of enabling and disabling menu items that make sense only
if you have a capture (except for "File/Save" and "File/Save As...", for
now) up to "load_cap_file()", "close_cap_file()", and the like - don't
scatter that stuff throughout the code.
Disable "File/Print Packet" if no packet is selected; enable it only if
a packet is selected.
If there's a selected packet, and a display filter is run:
if the selected packet passed the filter, re-select it;
if the selected packet didn't pass the filter, un-select it.
If we've opened a live "pcap" capture, but can't do the capture because
we can't get the netmask info, or can't parse the capture filter string,
or can't install the filter, close the live capture and the dump and
delete the dump file.
If we failed to open a live "pcap" capture, don't try to read the
capture file - it doesn't exist.

think I may have to worry about page boundaries and the like - so, for

frames, but it's still not ready for prime time.

There's no need to pass a pointer to a "dialog_button" variable to

that's set whenever we encounter an EOF; if that flag is set, all
subsequent reads return an EOF indication. I.e., end-of-file is sticky.
This means that the stuff to continue reading a capture file, if we're
updating the display as the capture progresses, doesn't work - it gets
stuck at the point where the first read finished.
To clear that flag, we must do an "fseek()"; we do one that doesn't move
the seek pointer.
When updating the display as a capture progresses, do
"init_col_widths()" only when we first open the capture file; there's no
need to do it every time we read from the file - the column widths never
get smaller, they can only get bigger or stay the same.

apply the filter (if it isn't invalid).
Apply the filter by clearing the Clist that shows packet summary lines
and scanning through the list of all packets and adding to the Clist
those that match the filter.
Get rid of "if (dfilter_proto_tree)" test in "load_cap_file()";
"dfilter_proto_tree" is always FALSE, and all the test does is keep us
from doing a "gtk_clist_freeze()" of the packet list, and we don't want
to do that (we don't want the packet to be updated until we're done
reading in the file).
Get rid of "dfilter_proto_tree", as it's no longer used.
Move the test that checks whether the display filter matches the current
packet to "add_packet_to_packet_list()"; this allows us to run
"dissect_packet()" only once - if we have a display filter, we generate
the summary info *and* the protocol tree in the same call, using the
summary info to make the packet list item and the protocol tree when
checking the display filter.
In "dfilter_compile()", destroy "*p_dfcode" if it's not NULL, so we
don't leak memory.

changed by updating those columns showing the time in the

influence came from
http://developer.apple.com/techpubs/mac/HIGuidelines/HIGuidelines-232.html
which has a section on dialog box and alert box messages. However,
we're largely dealing with technoids, not with The Rest Of Us, so I
didn't go as far as one perhaps should.)
Unfortunately, it looks like it's a bit more work to arrange that, if
you give a bad file name to the "-r" flag, the dialog box pop up only
*after* the main window pops up - it has the annoying habit of popping
up *before* the main window pops up, and sometimes getting *obscured* by
it, when I do that. The removal of the dialog box stuff from
"load_cap_file()" was intended to facilitate that work. (It might also
be nice if, when an open from the "File/Open" menu item fails, we keep
the file selection box open, and give the user a chance to correct
typos, choose another file name, etc.)
