when the new "Rotate capture file every n second(s)" checkbox or the
-b <# of file>[:<duration>] argument are used, [t]ethereal will skip to the
next ring buffer file if the specified duration has elapsed (even if the
specified capture size is not reached). This is useful when you want to have
separate capture files per hour or day for instance.
I let the autostop filesize parameter mandatory (i.e. the "rotate capture
file after n kilobytes") but this could be no longer strictly necessary when
that new feature is used ...
Another point: it might be interesting to really truncate the file at the
switch and not the closure ... According to user comments and my own real
case tests, I might plan to enhance this point and others (still ring buffer
related) in the future.

It can sometimes happen that capturing is stopped just after Ethereal
has switched to a new ring buffer. The result is that no frames
are displayed. The patch to ringbuffer.c displays the previous ring
buffer if the current buffer is empty on close.
The patch to capture.c fixes a bug where an error return from
ringbuf_wtap_dump_close was ignored, and tidies up the code around
the call.

Currently Ethereal sets and uses a default directory for reading
and writing, but only in some places. This set of patches extends
the setting of the default directory to the -w option as well as
the -r option, and causes all file dialogs to use and set the
default consistently. (I haven't changed the
Preferences/Printing/File dialog, though, as that's a special
case.)
There's also a fix for a bug where Ethereal was issuing the
message "Ring buffer requested, but capture isn't being saved to
a permanent file" even though a file was specified with -w.
There also appear to be some other cleanups in his patch.

It appears that the underlying problem with the timeout was that we

presumably wasn't working as it doesn't work on BPF devices on many
BSDs; the workaround no longer appears to be necessary, with Michael's
fix to treat MacOS X as BSD.
(Presumably a select timeout with "tv_usec" set to 1000*1000
microseconds was treated as an error, or otherwise treated in such a way
that it didn't block waiting for the BPF device to say it could be
read.)

This fixes some bugs:
1. With the -S option under Linux, Capture/Stop or ^E was
ignored until the next packet was read. This is because
capture.c wasn't checking for EINTR from select(), which is
returned when the child receives SIGUSR1 from the parent.
2. When reading from a pipe, a spurious error message from
pcap_open_live() was written to stderr.
3. Error messages from the child in Sync mode were displayed in
a Warning alert box.
Also, there's a new subroutine, popup_errmsg(), to replace
several instances of duplicate code.

"capture_file" structure - they're a property of an in-progress capture,
not a property of an open capture file. Make them just variables.
The maximum number of packets to be captured should be a variable
separate from the "count" field in the "capture_file" structure - the
latter is a count of the packets in the capture file in question.
Have Boolean variables indicating whether a maximum packet count,
maximum capture file size, and maximum capture duration were specified.
If an option isn't set, and we're doing an "update list of packets in
real time" capture, don't pass the option to the child process with a
command-line argument.
Don't create "stop when the capture file reaches this size" or "stop
when the capture's run for this long" conditions if a maximum capture
file size or a maximum capture duration, respectively, haven't been
specified. Don't test or free a condition if it wasn't created.
Don't allow a 0 argument to the "-c" flag - the absence of a "-c" flag
is the way you specify "no limit on the number of packets".
Initialize the check boxes and spin buttons for the "maximum packets to
capture", "maximum capture size", and "maximum capture duration" options
to the values they had in the last capture. If an option wasn't
specified, don't read its value from the dialog box and set the
variable.
svn path=/trunk/; revision=4795
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.

Don't add "-I" flags to search "epan", as that's no longer necessary

(by deleting the main window or selecting File->Quit or typing ^Q) while

When we exit, kill off any capture child, using that routine, and, if
we're exiting due to a request to delete the main window and, if a read
is in progress (from an "Update list of packets in real time" capture),
don't delete the main window - just set the "Read aborted" flag, so that
the code doing the read will see that flag (it will be called because
the pipe to the capture child is closed due to the child exiting) will
see that and clean up and exit itself.

"gboolean", as it's a Boolean value, and move it to the beginning of the

From Graeme Hewson:
Check for "pcap_dispatch()" returning -1, meaning an error
occurred; if it does, stop capturing, and report the error.
If we get a signal in tethereal, stop the capture with a
"longjmp()", rather than by clearning the "go" flag;
"pcap_dispatch()", on many platforms, keeps reading rather than
returning a captured packet count of 0 if the system call to
read packets returns -1 with an errno of EINTR, so the
"pcap_dispatch()" won't be broken out of if the signal handler
returns.
