redissect the packets and re-evaluate the display filter if any of them

"Cancel" also needs to find out if any preferences were changed by the

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
dialog, as it'll do so when it stops the operation.
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
appeared never to get called; we can just free the "progdlg_t" for the
dialog in "destroy_progress_dlg()", right after destroying the dialog
box widget.

it to an incompletely-defined structure to hide the implementation
details from the caller.
Make "create_progress_dlg()" take, as an argument, the title to put in
the "stop the operation" button, and use "Stop" rather than "Cancel" if
stopping the operation doesn't undo all the work it's done.
Thaw the clist if we break out of a "read the file" operation, as we
freeze it before the operation.
Have the handler for the "delete" event on the progress dialog box
return FALSE, to let GTK+ know that it should, in fact, delete the

return "void".)

same directory as the "manuf" file ("/etc" or "/usr/local/etc", most
likely).
Add a mechanism to allow modules (e.g., dissectors) to register
preference values, which:
can be put into the global or the user's preference file;
can be set from the command line, with arguments to the "-o"
flag;
can be set from tabs in the "Preferences" dialog box.
Use that mechanism to register the "Decode IPv4 TOS field as DiffServ
field" variable for IP as a preference.
Stuff that still needs to be done:
documenting the API for registering preferences;
documenting the "-o" values in the man page (probably needs a
flag similar to "-G", and a Perl script to turn the output into
documentation as is done with the list of field);
handling error checking for numeric values (range checking,
making sure that if the user changes the variable from the GUI
they change it to a valid numeric value);
using the callbacks to, for example, update the display when
preferences are changed (could be expensive);
panic if the user specifies a numeric value with a base other
than 10, 8, or 16.
We may also want to clean up the existing wired-in preferences not to
take effect the instant you tweak the widget, and to add an "Apply"

keep the dialog on top of the main window in the Z order for

perhaps (if there are any window managers that actually *do*
this) even put it atop the main window in the X-Y plane (KWM
doesn't and I seem to remember that the Exceed X server for
Windows doesn't).

reading a capture file, we should just clean up and return so that
Ethereal continues running with no capture file loaded, unless the read

which case we still exit (although we may eventually choose to continue
running with no capture file loaded even in that case).

potentially long-running operation that has a progress indicator, pop up
a modal dialog box with
an indication of what is being done;
a progress bar;
a "Cancel" button to stop the operation.
This:
leaves more room on the status line for a filter expression;
provides a mechanism to allow the user to cancel long-running
operations (although the way we do so may not back out of them
as nicely as the user might like, if it's not obvious what the
"right" way is or if the "right" way is difficult to implement
or involves doing as much work as letting the operation
continue);
means that, because the dialog box is modal, we don't have to
worry about the user performing arbitrary UI operations out from
under the operation and changing arbitrary bits of state being
used by that operation.

a pointer to the "wtap_pkthdr" structure for an open capture
file;
a pointer to the "wtap_pseudo_header" union for an open capture
file;
a pointer to the packet buffer for an open capture file;
so that a program using "wtap_read()" in a loop can get at those items.
Keep, in a "capture_file" structure, an indicator of whether:
no file is open;
a file is open, and being read;
a file is open, and is being read, but the user tried to quit
out of reading the file (e.g., by doing "File/Quit");
a file is open, and has been completely read.
Abort if we try to close a capture that's being read if the user hasn't
tried to quit out of the read.
Have "File/Quit" check if a file is being read; if so, just set the
state indicator to "user tried to quit out of it", so that the code
reading the file can do what's appropriate to clean up, rather than
closing the file out from under that code and causing crashes.
Have "read_cap_file()" read the capture file with a loop using
"wtap_read()", rather than by using "wtap_loop()"; have it check after
reading each packet whether the user tried to abort the read and, if so,
close the capture and return an indication that the read was aborted by
the user. Otherwise, return an indication of whether the read
completely succeeded or failed in the middle (and, if it failed, return
the error code through a pointer).
Have "continue_tail_cap_file()" read the capture file with a loop using
"wtap_read()", rather than by using "wtap_loop()"; have it check after
reading each packet whether the user tried to abort the read and, if so,
quit the loop, and after the loop finishes (even if it read no packets),
return an indication that the read was aborted by the user if that
happened. Otherwise, return an indication of whether the read
completely succeeded or failed in the middle (and, if it failed, return
the error code through a pointer).
Have "finish_tail_cap_file()" read the capture file with a loop using
"wtap_read()", rather than by using "wtap_loop()"; have it check after
reading each packet whether the user tried to abort the read and, if so,
quit the loop, and after the loop finishes (even if it read no packets),
close the capture and return an indication that the read was aborted by
the user if that happened. Otherwise, return an indication of whether
the read completely succeeded or failed in the middle (and, if it
failed, return the error code through a pointer).
Have their callers check whether the read was aborted or not and, if it
was, bail out in the appropriate fashion (exit if it's reading a file
specified by "-r" on the command line; exit the main loop if it's
reading a file specified with File->Open; kill the capture child if it's
"continue_tail_cap_file()"; exit the main loop if it's
"finish_tail_cap_file()".

there's no need to keep it around in memory - when the frame data is
read in when handing a frame, read in the information, if any, necessary
to reconstruct the frame header, and reconstruct it. This saves some
memory.
This requires that the seek-and-read function be implemented inside
Wiretap, and that the Wiretap handle remain open even after we've
finished reading the file sequentially.
This also points out that we can't really do X.25-over-Ethernet
correctly, as we don't know where the direction (DTE->DCE or DCE->DTE)
flag is stored; it's not clear how the Ethernet type 0x0805 for X.25
Layer 3 is supposed to be handled in any case. We eliminate
X.25-over-Ethernet support (until we find out what we're supposed to
do).

doing something that requires that the text for protocol tree entries be
generated, i.e.
1) initialize it to FALSE;
2) have every routine that sets it clear it when it's done;
3) when printing packets, set it to TRUE only if we're not just
printing packet summary lines;
and then get rid of settings to FALSE made unnecessary as a result of
those changes.
This makes sure it's not set when it doesn't have to be (which causes
the protocol tree code to format the text when it doesn't have to,
wasting CPU time).
