Guy Harris cf91fdf16b Have tap listeners specify whether the "packet" routine requires
a protocol tree;

	the column values.

This includes stats-tree listeners.

Have the routines to build the packet list, and to retap packets, honor
those requirements.  This means that cf_retap_packets() no longer needs
an argument to specify whether to construct the column values or not, so
get rid of that argument.

This also means that there's no need for a tap to have a fake filter
to ensure that the protocol tree will be built, so don't set up a fake
"frame" filter.

While we're at it, clean up some cases where "no filter" was represented
as a null string rather than a null pointer.

Have a routine to return an indication of the number of tap listeners
with filters; use that rather than the global num_tap_filters.

Clean up some indentation and some gboolean vs. gint items.

Guy Harris c4932893e3 Have separate callback mechanisms in file.c and capture.c; pass the
capture callbacks the capture_options * as its second argument in all
cases.  This makes it a bit clearer what arguments callbacks take, and
means we can get rid of all global_capture_opts references in
gtk/main_statusbar.c.

Put the interface between gtk/main.c and gtk/main_statusbar.c into a
private header.

Guy Harris ffcb641149 Again, the err_info returned from wtap_read() and wtap_seek_read() is a
g_mallocated string, so it's not const.

Fix a comment to reflect reality (err_info is some additional
information about the error returned by Wiretap, e.g. some gory details
about the error, mainly useful to developers and support people).

Stig Bjørlykke 5800abad46 From Francesco Fondelli (bug 2349):
Attached is a patch to export packets data as "C Arrays".  I often have
the need to [re]send data captured with wireshark using a raw/pf_packet socket.
Output format is one char[] per packet, it looks like almost the same as
the one produced by "Follow TCP stream".

Guy Harris 082282b6f4 Don't enable "Save As" if you don't have an unsaved live capture file
and there are no formats in which the file can be saved by some means
other than copying the raw data; "Save As" isn't a very useful function
in that case, and that prevents us from having an empty list of formats
in which the file can be saved.

Ulf Lamping 831c54c4f5 add two new callbacks:
cf_cb_file_closing (called before closing a capture file) cf_cb_file_closed will be called afterwards, but both only if a file is really closed as cf_close is called more often ...

If we are closing large capture files (~20MB), the screen looks ugly while the file is closed. Change this so the screen will immediately go back to initial state and a dialog (without buttons) is shown that the file is currently closed. As the operation which takes most of the time to close the file is a single eth_clist_clear call, we can't use a progress bar here.

cf_cb_live_capture_stopping: called when the user wants to stop the capture (toolbar or menu clicked). At least on Win32, the time between this and the actual stop completed can be noticeable (1-2 seconds), so the user doesn't know if the button press did anything at all. Do something similar as above, show a dialog box without buttons to inform that the close is in progress.

Ulf Lamping 84cf7ce767 added compression support for capture file output. The Save/As dialog now has a checkbox "Compress with gzip"
currently limited to Ethereal and all the variants of libpcap filetypes only.

We might want to add output compression support to the other tools as well (tethereal, mergecap, ...).

We might also want to add support for the other filetypes, but this is only possible if the filetype functions doesn't use special output operations like fseek.

One bug is still left: if the input and output filetypes while saving are the same, Ethereal currently optimizes this by simply copy the binary file instead of using wiretap (so it will be faster but it will ignore the compress setting). 

Don't know a good workaround for this, as I don't know a way to find out if the input file is currently compressed or not. One idea might be to use a heuristic on the filesize (compared to the packet size summmary). Another workaround I see is to remove this optimization, which is of course not the way I like to do it ...

Ulf Lamping 1c6b2cf0e3 Instead of calling each single thing when doing/finish a file operation, file.c shouldn't call all the GUI related functions itself, instead throwing some kind of Events to it's caller(s).
I've implemented a very simple callback mechanism which provides exactly this. I've tried GHook from GLib before, but this doesn't seem to be the right thing, as it's too inflexible for the purpose here.

So I've implemented a callback function in main.c which receives all "events" and spreads them to menu, statusbar and itself.

I would see this implementation as a prototype which may need  improvements. Please comment the changes.

Ulf Lamping 3a63719e38 another two steps towards privilege seperation:
move another two capture related fields (iface and cfilter) from cfile to capture_opts

also move the handling of capture related command line options from main.c to capture.c, that way a future privilege seperated capture program can use the same code to parse it's command line than Ethereal. 
It might be even possible to share this parser code even with Tethereal, didn't took a closer look at this.

cf_ functions, have separate ones for different classes of routines, and
use gboolean when the return value is just "success" or "failure" - that
way you don't get compiler warnings if a case statement isn't handling a
particular status value if the routine in question won't return it.

Guy Harris 6e622fd24e "gtk_entry_get_text()" returns a "const char *" - assign the result to
one.

"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
*" (which are allocated anew for each call, and can be modified, but
have to be freed).

Clean up white space.

Guy Harris d6cd61061e 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.
