so that we can properly associate a widget with create, update, and
destroy events. Only used by Qt so far but it should be easy enough to
add to GTK+.
Rename ui/qt/progress_dialog.{h,cpp} to progress_bar.{h,cpp}. Show a
progress bar in the status bar of the main window instead of creating
a separate dialog. Note that we still need to add a "cancel" mechanism
and display the task and item titles somewhere.
Thus began the War Against Gratuitous Dialogs.

tries to do "Save As" in a format for which we don't support comments
(currently, we only support them for pcap-ng), ask whether they want to
discard the comments and save anyway or, *if* the file can be saved in a
format for which we *do* support comments, they want to save the file in
some other format.
Keep a count of packet comments so that we don't have to scan all the
frame_data structures to determine whether we have any comments.

Show all of them in the summary dialog; we will be using it in the
future to figure out what capture file formats we can write to (just
because a capture file format supports per-packet encapsulations, that
doesn't mean that it supports *all possible* encapsulations).

"unsaved_changes", and have it be TRUE iff changes have been made to the
file since it was read - *not* if it's a temporary file from a live
capture.
Check the "is_tempfile" member, and the "unsaved_changes" member, when
appropriate.
Just have a set_toolbar_for_capture_file() routine that updates the
"save", "close", and "reload" toolbar as appropriate, given a
capture_file structure - absorb the function of
set_toolbar_for_unsaved_capture_file() into it.

sequence of frame_data structures, indexed by the frame number. Extract
the relevant bits of the capture_file data structure and move them to
the frame_data_sequence, and move the relevant code from cfile.c and
tweak it to handle frame_data_sequence structures.
Have a possibly-null pointer to a frame_data_sequence structure in the
capture_file structure; if it's null, we aren't keeping a sequence of
frame_data structures (we don't keep that sequence when we're doing
one-pass processing in TShark).
Nothing in libwireshark should care about a capture_file structure; get
rid of some unnecessary includes of cfile.h.

This lets us get rid of the per-frame_data-structure prev and next
pointers, saving memory (at least according to Activity Monitor's report
of the virtual address space size on my Snow Leopard machine, it's a
noticeable saving), and lets us look up frame_data structures by frame
number in O(log2(number of frames)) time rather than O(number of frames)
time. It seems to take more CPU time when reading in the file, but
seems to go from "finished reading in all the packets" to "displaying
the packets" faster and seems to free up the frame_data structures
faster when closing the file.
It *is* doing more copying, currently, as we now don't allocate the
frame_data structure until after the packet has passed the read filter,
so that might account for the additional CPU time.
(Oh, and, for what it's worth, on an LP64 platform, a frame_data
structure is exactly 128 bytes long. However, there's more stuff to
remove, so the power-of-2 size is not guaranteed to remain, and it's not
a power-of-2 size on an ILP32 platform.)
It also means we don't need GLib 2.10 or later for the two-pass mode in
TShark.
It also means some code in the TCP dissector that was checking
pinfo->fd->next to see if it's NULL, in order to see if this is the last
packet in the file, no longer works, but that wasn't guaranteed to work
anyway:
we might be doing a one-pass read through the capture in TShark;
we might be dissecting the frame while we're reading in the
packets for the first time in Wireshark;
we might be doing a live capture in Wireshark;
in which case packets might be prematurely considered "the last packet".
#if 0 the no-longer-working tests, pending figuring out a better way of
doing it.

Make the loops that scan through all the packets do so by frame number,
to abstract away the "next" and "previous" pointers in the frame_data
structure. Add a routine to cfile.c to map frame numbers to frame_data
structures, and put in some special case handling so scanning forward or
backward through the packets is O(N) rather than O(N^2).

1. Restore the functionality of <Ctrl>A and <Ctrl>X to the filter textbox.
2. Assign intuitive shortcuts without consuming any new shortcut letters.
3. Add 'Un-Time Reference All Packets' to the menu.
4. Disallow the marking or ignoring of all packets in the capture.
5. Make the Mark/Ignore/Time Reference-related menu items context sensitive.
6. Add 'ref_time_count' to the capture_file structure
7. Utilize marked/ignored/ref_time_count vars to prevent needless looping thru
the entire packet list by exiting the loop when it becomes zero.

that you can tell from examination whether the search is forward or
backward.
Make the cf_find_packet routines take the direction as an explicit
argument, rather than, in the cases where you don't want to permanently
set the direction, saving the direction in the capture_file structure,
changing it, doing the search, and restoring the saved direction. Give
more information in the Doxygen comments for those routines.
Add a cf_find_packet_dfilter_string() routine, which takes a filter
string rather than a compiled filter as an argument. Replace
find_previous_next_frame_with_filter() with it.
Have cf_read_frame_r() and cf_read_frame() pop up the error dialog if
the read fails, rather than leaving that up to its caller. That lets us
eliminate cf_read_error_message(), by swallowing its code into
cf_read_frame_r(). Add Doxygen comments for cf_read_frame_r() and
cf_read_frame().
Don't have find_packet() read the packet before calling the callback
routine; leave that up to the callback routine.
Add cf_find_packet_marked(), to find the next or previous marked packet,
and cf_find_packet_time_reference(), to find the next or previous time
reference packet. Those routines do *not* need to read the packet data
to see if it matches; that lets them run much faster.
Clean up indentation.

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...

(so if the file's gzipped, it's *NOT* the size of the file after
uncompressing), and an approximation of the amount of that data read
sequentially so far.
Use those for various progress bars and the like.
Make the fstat() in the Ascend trace reader directly use wth->fd, as
it's inside Wiretap; that gets rid of the last caller of wtap_fd() (as
we're no longer directly using fstat() or lseek() in Ethereal), so get
rid of wtap_fd().

move another two capture related fields (iface and cfilter) from cfile to capture_opts

Use "gtk_toggle_button_set_active()", not
"gtk_toggle_button_set_state()" (the latter is a deprecated alias for

so we shouldn't torment the users by offering it.
Check the string type and convert it to an internal representation in
the GUI code; have the search code deal only with the internal
representation.
Save the case-sensitivity flag, and the indication of where string
searches look, along with other search parameters.
Upper-casify the string, for case-insensitive searches, in the GUI code;
don't save the upper-casified string, so it doesn't SHOUT at you when
you next pop up a "find" dialog.
Convert the hex value string to raw binary data in the GUI code, rather
than doing so in the search code. Check that it's a valid string.
Connect the signals to the radio buttons after the pointers have been
attached to various GUI items - the signal handlers expect some of those
pointers to be attached, and aren't happy if they're not.
Have "find_packet()" contain a framework for searching, but not contain
the matching code; instead, pass it a pointer to a matching routine and
an opaque pointer to be passed to the matching routine. Have all the
routines that do different types of searching have their own matching
routines, and use the common "find_packet()" code, rather than
duplicating that code.
Search for the Info column by column type, not by name (the user can
change the name).
When matching on the protocol tree, don't format the entire protocol
tree into a big buffer - just have a routine that matches the text
representation of a protocol tree item against a string, and, if it
finds a match, sets a "we found a match flag" and returns; have that
routine not bother doing any more work if that flag is set.
(Unfortunately, you can't abort "g_node_children_foreach()" in the
middle of a traversal.)
Free the generated display filter code after a find-by-display-filter
finishes.
