Get rid of the EBCDIC stuff in the find dialog - it's not supported yet,
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.

Instead of using a Boolean for the search direction, use an enum, so
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.

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.

Instead of using a Boolean for the search direction, use an enum, so
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

Get rid of the EBCDIC stuff in the find dialog - it's not supported yet,
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.

Allow the user to save either all of the current capture, or only the
packets that are currently being displayed from that capture.
Centralize the code to control whether "File:Save" and "File:Save As"
are enabled (and *always* have "File:Save As" enabled if you have a
capture; "File:Save" is enabled only if you have a live capture you've
not yet saved, although it does the same thing as "File:Save As").
Have the "save_file" member of a "capture_file" structure represent
*only* the file currently being *written* to by a capture, and, if there
is no capture currently in progress, have it be NULL; the name of the
file currently being *displayed" is in the "filename" member, and an
"is_tempfile" member indicates whether it's a temporary file for a live
capture or not.
Have "close_cap_file()" delete the current capture file if it's a
temporary capture file that hasn't been saved (in its entirety - saving
selected frames doesn't count). Do the same (if there *is* a current
capture file) when exiting.
The "Ready to load or capture" message is the only statusbar message in
the "main" context; "close_cap_file()" should never pop it, it should
only pop whatever message exists in the "file" context, and thus has no
need to take, as an argument, the context for the message it should pop.
Update the man page to reflect the new behavior of "File:Save" and
"File:Save As", and to reflect recent changes to "Display:Match Selected".

Split "load_cap_file()" into "open_cap_file()" and "read_cap_file()".
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.

Have the Wiretap open, read, and seek-and-read routines return, in
addition to an error code, an error info string, for
WTAP_ERR_UNSUPPORTED, WTAP_ERR_UNSUPPORTED_ENCAP, and
WTAP_ERR_BAD_RECORD errors. Replace the error messages logged with
"g_message()" for those errors with g_strdup()ed or g_strdup_printf()ed
strings returned as the error info string, and change the callers of
those routines to, for those errors, put the info string into the
printed message or alert box for the error.
Add messages for cases where those errors were returned without printing
an additional message.
Nobody uses the error code from "cf_read()" - "cf_read()" puts up the
alert box itself for failures; get rid of the error code, so it just
returns a success/failure indication.
Rename "file_read_error_message()" to "cf_read_error_message()", as it
handles read errors from Wiretap, and have it take an error info string
as an argument. (That handles a lot of the work of putting the info
string into the error message.)
Make some variables in "ascend-grammar.y" static.
Check the return value of "erf_read_header()" in "erf_seek_read()".
Get rid of an unused #define in "i4btrace.c".

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.

Add routines to Wiretap to allow a client of Wiretap to get:
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()".

Allow the user to save either all of the current capture, or only the
packets that are currently being displayed from that capture.
Centralize the code to control whether "File:Save" and "File:Save As"
are enabled (and *always* have "File:Save As" enabled if you have a
capture; "File:Save" is enabled only if you have a live capture you've
not yet saved, although it does the same thing as "File:Save As").
Have the "save_file" member of a "capture_file" structure represent
*only* the file currently being *written* to by a capture, and, if there
is no capture currently in progress, have it be NULL; the name of the
file currently being *displayed" is in the "filename" member, and an
"is_tempfile" member indicates whether it's a temporary file for a live
capture or not.
Have "close_cap_file()" delete the current capture file if it's a
temporary capture file that hasn't been saved (in its entirety - saving
selected frames doesn't count). Do the same (if there *is* a current
capture file) when exiting.
The "Ready to load or capture" message is the only statusbar message in
the "main" context; "close_cap_file()" should never pop it, it should
only pop whatever message exists in the "file" context, and thus has no
need to take, as an argument, the context for the message it should pop.
Update the man page to reflect the new behavior of "File:Save" and
"File:Save As", and to reflect recent changes to "Display:Match Selected".

Have Wiretap set the snapshot length to 0 if it can't be derived from
reading the capture file. Have callers of "wtap_snapshot_length()"
treat a value of 0 as "unknown", and default to WTAP_MAX_PACKET_SIZE (so
that, when writing a capture file in a format that *does* store the
snapshot length, we can at least put *something* in the file).
If we don't know the snapshot length of the current capture file, don't
display a value in the summary window.
Don't use "cfile.snap" as the snapshot length option when capturing -
doing so causes Ethereal to default, when capturing, to the snapshot
length of the last capture file that you read in, rather than to the
snapshot length of the last capture you did (or the initial default of
"no snapshot length").
Redo the "Capture Options" dialog box to group options into sections
with frames around them, and add units to the snapshot length, maximum
file size, and capture duration options, as per a suggestion by Ulf
Lamping. Also add units to the capture count option.
Make the snapshot length, capture count, maximum file size, and capture
duration options into a combination of a check box and a spin button.
If the check box is not checked, the limit in question is inactive
(snapshot length of 65535, no max packet count, no max file size, no max
capture duration); if it's checked, the spinbox specifies the limit.
Default all of the check boxes to "not checked" and all of the spin
boxes to small values.
Use "gtk_toggle_button_get_active()" rather than directly fetching the
state of a check box.

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

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()".

Allow the user to save either all of the current capture, or only the
packets that are currently being displayed from that capture.
Centralize the code to control whether "File:Save" and "File:Save As"
are enabled (and *always* have "File:Save As" enabled if you have a
capture; "File:Save" is enabled only if you have a live capture you've
not yet saved, although it does the same thing as "File:Save As").
Have the "save_file" member of a "capture_file" structure represent
*only* the file currently being *written* to by a capture, and, if there
is no capture currently in progress, have it be NULL; the name of the
file currently being *displayed" is in the "filename" member, and an
"is_tempfile" member indicates whether it's a temporary file for a live
capture or not.
Have "close_cap_file()" delete the current capture file if it's a
temporary capture file that hasn't been saved (in its entirety - saving
selected frames doesn't count). Do the same (if there *is* a current
capture file) when exiting.
The "Ready to load or capture" message is the only statusbar message in
the "main" context; "close_cap_file()" should never pop it, it should
only pop whatever message exists in the "file" context, and thus has no
need to take, as an argument, the context for the message it should pop.
Update the man page to reflect the new behavior of "File:Save" and
"File:Save As", and to reflect recent changes to "Display:Match Selected".

Store the frame_data structures in a tree, rather than a linked list.
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.

Add routines to Wiretap to allow a client of Wiretap to get:
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

not yet saved, although it does the same thing as "File:Save As").
Have the "save_file" member of a "capture_file" structure represent
*only* the file currently being *written* to by a capture, and, if there
is no capture currently in progress, have it be NULL; the name of the
file currently being *displayed" is in the "filename" member, and an
"is_tempfile" member indicates whether it's a temporary file for a live
capture or not.
Have "close_cap_file()" delete the current capture file if it's a
temporary capture file that hasn't been saved (in its entirety - saving
selected frames doesn't count). Do the same (if there *is* a current
capture file) when exiting.
The "Ready to load or capture" message is the only statusbar message in
the "main" context; "close_cap_file()" should never pop it, it should
only pop whatever message exists in the "file" context, and thus has no
need to take, as an argument, the context for the message it should pop.
Update the man page to reflect the new behavior of "File:Save" and
"File:Save As", and to reflect recent changes to "Display:Match Selected".

"gtk_entry_get_text()" returns a "const char *" - assign the result to

"get_basename()" doesn't modify its argument, and its callers don't
modify the substring pointed to by the result, so make it take a "const
char *" as an argument and return a "const char *".
"find_last_pathname_separator()" doesn't modify its argument, so make it
a "const char *" - but some of its callers pass a non-"const" "char *"
and modify the result, so don't make its return value a "const char *".
And, as none of its callers are outside "filesystem.c", make it static.
In "about_folders_page_new()", have separate variables for pathnames
returned as "const char *" (which are cached by the routine that returns
them, so you can't modify them - and can't free them, so get rid of the
commented-out "g_free()" calls for them) and pathnames returned as "char

have to be freed).

Add routines to Wiretap to allow a client of Wiretap to get:
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()".

Have the Wiretap open, read, and seek-and-read routines return, in
addition to an error code, an error info string, for
WTAP_ERR_UNSUPPORTED, WTAP_ERR_UNSUPPORTED_ENCAP, and
WTAP_ERR_BAD_RECORD errors. Replace the error messages logged with
"g_message()" for those errors with g_strdup()ed or g_strdup_printf()ed
strings returned as the error info string, and change the callers of
those routines to, for those errors, put the info string into the
printed message or alert box for the error.
Add messages for cases where those errors were returned without printing
an additional message.
Nobody uses the error code from "cf_read()" - "cf_read()" puts up the
alert box itself for failures; get rid of the error code, so it just
returns a success/failure indication.
Rename "file_read_error_message()" to "cf_read_error_message()", as it
handles read errors from Wiretap, and have it take an error info string
as an argument. (That handles a lot of the work of putting the info
string into the error message.)
Make some variables in "ascend-grammar.y" static.
Check the return value of "erf_read_header()" in "erf_seek_read()".
Get rid of an unused #define in "i4btrace.c".

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).

Store the frame_data structures in a tree, rather than a linked list.
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.

Add messages for cases where those errors were returned without printing
an additional message.
Nobody uses the error code from "cf_read()" - "cf_read()" puts up the
alert box itself for failures; get rid of the error code, so it just
returns a success/failure indication.
Rename "file_read_error_message()" to "cf_read_error_message()", as it
handles read errors from Wiretap, and have it take an error info string
as an argument. (That handles a lot of the work of putting the info
string into the error message.)

DLT_NULL, from "libpcap", means different things on different platforms
and in different capture files; throw in some heuristics to try to
figure out whether the 4-byte header is:
1) PPP-over-HDLC (some version of ISDN4BSD?);
2) big-endian AF_ value (BSD on big-endian platforms);
3) little-endian AF_ value (BSD on little-endian platforms);
4) two octets of 0 followed by an Ethernet type (Linux, at least
on little-endian platforms, as mutated by "libpcap").
Make a separate Wiretap encapsulation type, WTAP_ENCAP_NULL,
corresponding to DLT_NULL.
Have the PPP code dissect the frame if it's PPP-over-HDLC, and have
"ethertype()" dissect the Ethernet type and the rest of the packet if
it's a Linux-style header; dissect it ourselves only if it's an AF_
value.
Have Wiretap impose a maximum packet size of 65535 bytes, so that it
fails more gracefully when handed a corrupt "libpcap" capture file
(other capture file formats with more than a 16-bit capture length
field, if any, will have that check added later), and put that size in
"wtap.h" and have Ethereal use it as its notion of a maximum packet
size.
Have Ethereal put up a "this file appears to be damaged or corrupt"
message box if Wiretap returns a WTAP_ERR_BAD_RECORD error when opening
or reading a capture file.
Include loopback interfaces in the list of interfaces offered by the
"Capture" dialog box, but put them at the end of the list so that it
doesn't default to a loopback interface unless there are no other
interfaces. Also, don't require that an interface in the list have an
IP address associated with it, and only put one entry in the list for a
given interface (SIOCGIFCONF returns one entry per interface *address*,
not per *interface* - and even if you were to use only IP addresses, an
interface could conceivably have more than one IP address).
Exclusively use Wiretap encapsulation types internally, even when
capturing; don't use DLT_ types.

Allow the user to save either all of the current capture, or only the
packets that are currently being displayed from that capture.
Centralize the code to control whether "File:Save" and "File:Save As"
are enabled (and *always* have "File:Save As" enabled if you have a
capture; "File:Save" is enabled only if you have a live capture you've
not yet saved, although it does the same thing as "File:Save As").
Have the "save_file" member of a "capture_file" structure represent
*only* the file currently being *written* to by a capture, and, if there
is no capture currently in progress, have it be NULL; the name of the
file currently being *displayed" is in the "filename" member, and an
"is_tempfile" member indicates whether it's a temporary file for a live
capture or not.
Have "close_cap_file()" delete the current capture file if it's a
temporary capture file that hasn't been saved (in its entirety - saving
selected frames doesn't count). Do the same (if there *is* a current
capture file) when exiting.
The "Ready to load or capture" message is the only statusbar message in
the "main" context; "close_cap_file()" should never pop it, it should
only pop whatever message exists in the "file" context, and thus has no
need to take, as an argument, the context for the message it should pop.
Update the man page to reflect the new behavior of "File:Save" and
"File:Save As", and to reflect recent changes to "Display:Match Selected".

Store the frame_data structures in a tree, rather than a linked list.
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.

Store the frame_data structures in a tree, rather than a linked list.
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.

We can't trust "cf->current_frame" to refer to the frame that was
selected before we started re-colorizing or re-filtering the display, as
when the first row is added to the clist, that may be selected and thus
made the current frame.
This means that we can't find the row corresponding to the
previously-selected frame, if any, by checking as each packet is
colorized/filtered and see whether its "frame_data" structure is equal
to "cf->current_frame", as that'll always say that the first frame in
the display is the selected frame.
Instead, we recored the value of "cf->current_frame" before we do
anything to the clist, have "add_packet_to_packet_list()" return either
the row number of the frame (if it passed the filter and thus was added
to the clist) or -1 (if it didn't pass the filter and thus wasn't added
to the clist), and, after "add_packet_to_packet_list()", if the current
frame is the one that was the selected row, remember its row number (if
any), and, when we're finished colorizing/filtering the display, make
that row the current row if it's not -1 (-1 means that the selected row
didn't pass the filter).
Also, don't do that until after we've thawed the clist, as the vertical
adjustment for the clist doesn't reflect reality until then, and
attempting to go to a given row won't work right until the vertical
adjustment for the clist reflects reality.
Shove all the code to set the selected and focus rows, and to make said
row visible, into a routine, so the "Find Frame" and "Go To Frame" code
can use it as well.

Store the frame_data structures in a tree, rather than a linked list.
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".

Add routines to Wiretap to allow a client of Wiretap to get:
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()".

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.

cf_read_frame_r(capture_file *cf, frame_data *fdata,
|
Instead of using a Boolean for the search direction, use an enum, so
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.

Instead of using a Boolean for the search direction, use an enum, so
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.

Also, don't do that until after we've thawed the clist, as the vertical

Store the frame_data structures in a tree, rather than a linked list.
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.

Instead of using a Boolean for the search direction, use an enum, so
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.

the row number of the frame (if it passed the filter and thus was added

that row the current row if it's not -1 (-1 means that the selected row

Also, don't do that until after we've thawed the clist, as the vertical

attempting to go to a given row won't work right until the vertical

Have "close_cap_file()" disable all menu items that make sense only if
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.

/* Get the packet */

Instead of using a Boolean for the search direction, use an enum, so
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.

Get rid of the EBCDIC stuff in the find dialog - it's not supported yet,
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.

Instead of using a Boolean for the search direction, use an enum, so
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.

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.

Get rid of the EBCDIC stuff in the find dialog - it's not supported yet,
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.

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

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

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.

Instead of using a Boolean for the search direction, use an enum, so
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.

Get rid of the EBCDIC stuff in the find dialog - it's not supported yet,
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

Get rid of the EBCDIC stuff in the find dialog - it's not supported yet,
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.)

Instead of using a Boolean for the search direction, use an enum, so
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.

Instead of using a Boolean for the search direction, use an enum, so
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.

Instead of using a Boolean for the search direction, use an enum, so
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.

Get rid of the EBCDIC stuff in the find dialog - it's not supported yet,
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

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.

Get rid of the EBCDIC stuff in the find dialog - it's not supported yet,
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.

Instead of using a Boolean for the search direction, use an enum, so
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.

We already set the foreground and background color for every frame,
which means we're already doing a "do something to the last row in the
packet list" operation on every frame we add to the list, so adding a
call to "gtk_clist_set_row_data()" won't make matters worse.
In addition, we already set one column in a row on a "change time
format" operation, so finding the row for a frame by calling
"gtk_clist_find_row_from_data()" doesn't turn a constant-time operation
into a linear-time operation, it just cranks the proportionality
constant up - it was quadratic before, alas, and it's still quadratic.
Adding calls to "gtk_clist_find_row_from_data()" to the "Find Frame" and
"Go To Frame" code does add an extra linear operation there, but those
operations shouldn't be common - and "Go To Frame", going to the last
frame on an ~100,000-frame big capture file, was quick, at least on my
450 MHz Pentium II machine, so maybe it won't be too bad.
And "select_packet()" either has to search the frame table for the frame
with the specified row number, or has to call "gtk_clist_get_row_data()"
to do that - the first is linear in the position of the frame in the
frame table, and the latter is linear in its position in the CList, and
the latter is less than or equal to the former, so the only thing making
it worse would be a change in the proportionality constant.
So it probably won't hurt performance by much.
Furthermore, if we add the ability to sort the display on an arbitrary
column, or to delete frames from the display - both of which are in the
wish list - storing the row number of the frame in the "frame_data"
structure won't necessarily work, as the row number can change out from
under us.
Therefore, reinstate the old way of doing things, where we associate
with each row a pointer to the "frame_data" structure for the row, using
"gtk_clist_set_row_data()".

"packet_list_select_cb()" to be called, which causes "cf_select_packet()"

2000-03-12 03:13:58 +00:00

"cf_select_packet()" fetches, above, the data associated with the

2000-03-12 03:13:58 +00:00

row that was selected; however, as "gtk_clist_append()", which
|

|
called "real_insert_row()", hasn't yet returned, we haven't yet
|
|
|
|
associated any data with that row, so we get back a null pointer.
|
|
|
|
|
|
|
|
We can't assume that there's only one frame in the frame list,
|
|
|
|
either, as we may be filtering the display.
|
|
|
|
|
|
|
|
We therefore assume that, if "row" is 0, i.e. the first row
|
|
|
|
is being selected, and "cf->first_displayed" equals
|
|
|
|
"cf->last_displayed", i.e. there's only one frame being
|
|
|
|
displayed, that frame is the frame we want.
|
|
|
|
|
|
|
|
This means we have to set "cf->first_displayed" and
|
|
|
|
"cf->last_displayed" before adding the row to the

GtkCList; see the comment in "add_packet_to_packet_list()". */

Instead of using a Boolean for the search direction, use an enum, so
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.

We can't trust "cf->current_frame" to refer to the frame that was
selected before we started re-colorizing or re-filtering the display, as
when the first row is added to the clist, that may be selected and thus
made the current frame.
This means that we can't find the row corresponding to the
previously-selected frame, if any, by checking as each packet is
colorized/filtered and see whether its "frame_data" structure is equal
to "cf->current_frame", as that'll always say that the first frame in
the display is the selected frame.
Instead, we recored the value of "cf->current_frame" before we do
anything to the clist, have "add_packet_to_packet_list()" return either
the row number of the frame (if it passed the filter and thus was added
to the clist) or -1 (if it didn't pass the filter and thus wasn't added
to the clist), and, after "add_packet_to_packet_list()", if the current
frame is the one that was the selected row, remember its row number (if
any), and, when we're finished colorizing/filtering the display, make
that row the current row if it's not -1 (-1 means that the selected row
didn't pass the filter).
Also, don't do that until after we've thawed the clist, as the vertical
adjustment for the clist doesn't reflect reality until then, and
attempting to go to a given row won't work right until the vertical
adjustment for the clist reflects reality.
Shove all the code to set the selected and focus rows, and to make said
row visible, into a routine, so the "Find Frame" and "Go To Frame" code
can use it as well.

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.

Improve the alert boxes put up for file open/read/write errors. (Some
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.)

Allow the user to save either all of the current capture, or only the

Centralize the code to control whether "File:Save" and "File:Save As"
are enabled (and *always* have "File:Save As" enabled if you have a
capture; "File:Save" is enabled only if you have a live capture you've
not yet saved, although it does the same thing as "File:Save As").
Have the "save_file" member of a "capture_file" structure represent
*only* the file currently being *written* to by a capture, and, if there
is no capture currently in progress, have it be NULL; the name of the
file currently being *displayed" is in the "filename" member, and an
"is_tempfile" member indicates whether it's a temporary file for a live
capture or not.
Have "close_cap_file()" delete the current capture file if it's a
temporary capture file that hasn't been saved (in its entirety - saving
selected frames doesn't count). Do the same (if there *is* a current
capture file) when exiting.
The "Ready to load or capture" message is the only statusbar message in
the "main" context; "close_cap_file()" should never pop it, it should
only pop whatever message exists in the "file" context, and thus has no
need to take, as an argument, the context for the message it should pop.
Update the man page to reflect the new behavior of "File:Save" and
"File:Save As", and to reflect recent changes to "Display:Match Selected".

that you can tell from examination whether the search is forward or

Make the cf_find_packet routines take the direction as an explicit

set the direction, saving the direction in the capture_file structure,
changing it, doing the search, and restoring the saved direction. Give

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

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.)

returns a success/failure indication.

DLT_NULL, from "libpcap", means different things on different platforms
and in different capture files; throw in some heuristics to try to
figure out whether the 4-byte header is:
1) PPP-over-HDLC (some version of ISDN4BSD?);
2) big-endian AF_ value (BSD on big-endian platforms);
3) little-endian AF_ value (BSD on little-endian platforms);
4) two octets of 0 followed by an Ethernet type (Linux, at least
on little-endian platforms, as mutated by "libpcap").
Make a separate Wiretap encapsulation type, WTAP_ENCAP_NULL,
corresponding to DLT_NULL.
Have the PPP code dissect the frame if it's PPP-over-HDLC, and have
"ethertype()" dissect the Ethernet type and the rest of the packet if
it's a Linux-style header; dissect it ourselves only if it's an AF_
value.
Have Wiretap impose a maximum packet size of 65535 bytes, so that it
fails more gracefully when handed a corrupt "libpcap" capture file
(other capture file formats with more than a 16-bit capture length
field, if any, will have that check added later), and put that size in
"wtap.h" and have Ethereal use it as its notion of a maximum packet
size.
Have Ethereal put up a "this file appears to be damaged or corrupt"
message box if Wiretap returns a WTAP_ERR_BAD_RECORD error when opening
or reading a capture file.
Include loopback interfaces in the list of interfaces offered by the
"Capture" dialog box, but put them at the end of the list so that it
doesn't default to a loopback interface unless there are no other
interfaces. Also, don't require that an interface in the list have an
IP address associated with it, and only put one entry in the list for a
given interface (SIOCGIFCONF returns one entry per interface *address*,
not per *interface* - and even if you were to use only IP addresses, an
interface could conceivably have more than one IP address).
Exclusively use Wiretap encapsulation types internally, even when
capturing; don't use DLT_ types.

Improve the alert boxes put up for file open/read/write errors. (Some
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.)

Allow the user to save either all of the current capture, or only the
packets that are currently being displayed from that capture.
Centralize the code to control whether "File:Save" and "File:Save As"
are enabled (and *always* have "File:Save As" enabled if you have a
capture; "File:Save" is enabled only if you have a live capture you've
not yet saved, although it does the same thing as "File:Save As").
Have the "save_file" member of a "capture_file" structure represent
*only* the file currently being *written* to by a capture, and, if there
is no capture currently in progress, have it be NULL; the name of the
file currently being *displayed" is in the "filename" member, and an
"is_tempfile" member indicates whether it's a temporary file for a live
capture or not.
Have "close_cap_file()" delete the current capture file if it's a
temporary capture file that hasn't been saved (in its entirety - saving
selected frames doesn't count). Do the same (if there *is* a current
capture file) when exiting.
The "Ready to load or capture" message is the only statusbar message in
the "main" context; "close_cap_file()" should never pop it, it should
only pop whatever message exists in the "file" context, and thus has no
need to take, as an argument, the context for the message it should pop.

not yet saved, although it does the same thing as "File:Save As").
Have the "save_file" member of a "capture_file" structure represent
*only* the file currently being *written* to by a capture, and, if there
is no capture currently in progress, have it be NULL; the name of the
file currently being *displayed" is in the "filename" member, and an
"is_tempfile" member indicates whether it's a temporary file for a live
capture or not.
Have "close_cap_file()" delete the current capture file if it's a
temporary capture file that hasn't been saved (in its entirety - saving
selected frames doesn't count). Do the same (if there *is* a current
capture file) when exiting.
The "Ready to load or capture" message is the only statusbar message in
the "main" context; "close_cap_file()" should never pop it, it should
only pop whatever message exists in the "file" context, and thus has no
need to take, as an argument, the context for the message it should pop.
Update the man page to reflect the new behavior of "File:Save" and
"File:Save As", and to reflect recent changes to "Display:Match Selected".
