2004-01-31Pass ESD_BTN_OK rather than NULL as a second argument toGuy Harris1-20/+21
"simple_dialog()"; NULL might be #defined to be a pointer expression on some platforms, causing compiler warnings (and, on platforms where a null pointer doesn't have all its bits 0, possibly causing misbehavior, although I don't think there are any such platforms on which Ethereal runs). Don't allow 0 as button mask argument to "simple_dialog()". Squelch a compiler warning. Report fatal problems as errors, not warnings. Report file I/O errors with "file_open_error_message()". Report file write errors (including those reported by "close()", e.g. some errors writing to an NFS server) when saving raw packet data to a file. svn path=/trunk/; revision=9915

2004-01-31If "pcap_compile()" fails to compile an empty filter string (because,Guy Harris1-2/+2
for example, the libpcap code generator doesn't support the link-layer type for the capture), "dfilter_compile()" will succeed but return a null rfcode pointer. In that case, instead of telling people that it looks like a valid display filter (which it does, but it also looks like a complete list of all the Basque words likely to be known by Hammurabi :-)), and then crashing when we try to "free" that non-existent dfilter code, we just report it as a "sorry, couldn't compile that capture filter. svn path=/trunk/; revision=9912
2004-01-25Have the Wiretap open, read, and seek-and-read routines return, inGuy Harris1-2/+2
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". svn path=/trunk/; revision=9852
2004-01-24Add a new "file_open_error_message()" routine in "epan/filesystem.c", toGuy Harris1-2/+3
translate UNIX errno values to a somewhat friendly message format string. Rename "file_open_error_message()" in "file.c" to "cf_open_error_message()", make "cf_open_error_message()" use the new "file_open_error_message()" for UNIX errno values, have "do_capture()" in "capture.c" use "file_open_error_message()" to report errors from "open()", and make "cf_open_error_message()" static as nothing outside "file.c" uses it. Do similar stuff in "tethereal.c". svn path=/trunk/; revision=9821

prevent problems when switching between GTK1 and GTK2 ethereal versions b.) added new feature "Edit->Go To First Packet" "Edit->Go To Last Packet" with corresponding menu and toolbar items c.) added new feature "View->Zoom In" / "View->Zoom Out" / View->Normal Size" with corresponding menu and toolbar items This feature will act as a "size offset" to the current fontsize, so that the packet list/tree view/... will have a larger/smaller font size. The value is stored inside the recent file. d.) Win32 only: Try to get the win32 system font and fontsize at program startup and show the menus/dialogs and such with the same font and fontsize like other win32 windows. This makes the program make a *lot* more feel like a normal win32 program. svn path=/trunk/; revision=9753

2003-05-15Implement a ring buffer switch duration:Laurent Deniel1-1/+21
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. svn path=/trunk/; revision=7678
2003-04-24Don't ignore SIGCHLD - doing so means that, on many platforms, we don'tGuy Harris1-2/+1

2003-01-23From a look at the Linux ARCNET code, it appears that no frame deliveredGuy Harris1-3/+3
to the networking stack will have an exception frame header. Note, however, that on the BSD's ARCNET might be a bit of a mess. svn path=/trunk/; revision=6986
2003-01-23Add a "capture_arcnet()" routine and use it when capturing.Guy Harris1-1/+8
In "dissect_arcnet_common()", fetch the protocol ID using the correct offset rather than a hardwired 4. svn path=/trunk/; revision=6982
2003-01-03Rename WTAP_ENCAP_ATM_SNIFFER to WTAP_ENCAP_ATM_PDUS, as it's not justGuy Harris1-2/+2
used for the DOS-based ATM Sniffer. (That's not a great name, but I couldn't think of a better one.) Add a new WTAP_ENCAP_ATM_PDUS_UNTRUNCATED encapsulation type for capture files where reassembled frames don't have trailers, such as the AAL5 trailer, chopped off. That's what at least some versions of the Windows-based ATM Sniffer appear to have. Map the ATM capture file type for NetXRay captures to WTAP_ENCAP_ATM_PDUS_UNTRUNCATED, and put in stuff to fill in what we've reverse-engineered, so far, for the pseudo-header; there's more that needs to be done on it, e.g. getting the channel, AAL type, and traffic type (or inferring them if they're not in the packet header). svn path=/trunk/; revision=6840
2003-01-01Re-word-wrap the "you can't capture on PPP/WAN interfaces on NT"Guy Harris1-3/+3
message, to make the margins more even and to bring the second line under 80 characters. (It's amazing how long Herman Hollerith's legacy has lasted....) svn path=/trunk/; revision=6835
