* Always use "g_free()" to free "ifc.ifc_buf"; it's set to a valueGuy Harris2000-09-071-2/+2
| | | | | | | | | allocated by "g_malloc()", and one should always use "g_free()" to free stuff allocated with "g_malloc()" (using "free()" works if GLib isn't compiled with any special memory allocator debugging/profiling options, but doesn't work if it is compiled with those options). svn path=/trunk/; revision=2393

* Miscellaneous code cleaningLaurent Deniel2000-08-111-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - add <stdarg.h> or <varargs.h> in snprintf.h and remove those inclusions in the other #ifdef NEED_SNPRINTF_H codes - remove the check of multiple inclusions in source (.c) code (there is a bit loss of _cpp_ performance, but I prefer the gain of code reading and maintenance; and nowadays, disk caches and VM are correctly optimized ;-). - protect all (well almost) header files against multiple inclusions - add header (i.e. GPL license) in some include files - reorganize a bit the way header files are included: First: #include <system_include_files> #include <external_package_include_files (e.g. gtk, glib etc.)> Then #include "ethereal_include_files" with the correct HAVE_XXX or NEED_XXX protections. - add some HAVE_XXX checks before including some system header files - add the same HAVE_XXX in wiretap as in ethereal Please forgive me, if I break something (I've only compiled and regression tested on Linux). svn path=/trunk/; revision=2254
* Add a routine to check whether a file is a directory or not.Guy Harris2000-07-311-1/+46
| | | | | | | | | | | | | | | | | | To test whether a file the user selected to be opened from the file selection box is really a directory (so that we can point the file selection box at it, rather than trying to open the directory as a capture file, which wouldn't work), use the routine in question. To make the GTK+ file selection box start out in the last directory from which we opened a file, use "gtk_file_selection_complete()", rather than "chdir()"ing to that directory. Those changes keep us from "chdir()"ing all over the place; that way, if Ethereal dumps core, the core dump shows up in the directory from which it was run, rather than in the directory from which you last opened or into which you last saved a file. svn path=/trunk/; revision=2190

| | | | | | | | | | properly handle ASCII vs. Unicode in the list of interfaces; initialize Winsock before starting a capture, so that the code in the Win32 libpcap to get the IP address and netmask by translating the host name to an IP address works. svn path=/trunk/; revision=1737

* Don't put "get_home_dir()" inside #ifdef HAVE_LIBPCAP/#endif.Guy Harris2000-01-291-10/+26
| | | | | | | | | | | On UNIX, if "$HOME" isn't set, try getting the user ID and the password entry for that user ID, and, if that succeeds, get the home directory from the password entry, otherwise use "/tmp". On NT, it may be possible to do something similar (get the user name, and append that to "C:\winnt\profiles\"); I'm not sure whether there's anything that can be done on Windows 9x. svn path=/trunk/; revision=1580
* Remove instances of getenv("HOME") and provide a get_home_dir() functionGilbert Ramirez2000-01-291-1/+30

| | | | | | | | | | | | | | either a pointer to the directory part of the pathname (after stomping on the pathname separator with a '\0', so don't use this on pathnames you plan to use afterwards), or NULL if the pathname contains no directory part, and make it handle Win32 pathnames on Win32 systems. Use it to get the containing directory of the currently open file, so that the "chdir()" stuff we do to cause the "File:Open" dialog box to show you files in the directory in which you last looked works on Win32 systems. svn path=/trunk/; revision=1555
* Encapsulate the code to take a pointer to a pathname and return aGuy Harris2000-01-251-1/+38
| | | | | | | | pointer to the name of the file to which it refers (i.e., to the last component of the pathname) in a "get_basename()" routine, and have the code in "file.c" call it. svn path=/trunk/; revision=1552
* Move the routine to get a list of the network interfaces on the systemGuy Harris2000-01-161-1/+209
| | | | | | | | | to "util.c", and provide a routine to free that list as well. When picking an interface on which to do a capture (if no "-i" flag was specified), use that routine, and pick the first interface on the list. svn path=/trunk/; revision=1495
* Merge in the final code to make Ethereal run on Win32, compiledGilbert Ramirez2000-01-151-1/+5
| | | | | | | | | | | | | | | | with MSVC 6.0 and 'nmake', the make tool that comes with MSVC. It compiles, links, and runs. It doesn't run correctly. There's a problem when reading files. I'm getting short reads. I'm not linking in zlib or libsnmp because it first needs to be debugged. I changed the plugin code to use gmodule instead of libltdl, but the Unix build still links ethereal against libltdl. I'll fix that tonight; sorry about leaving it in such a sad state, but I wanted to check in this code before I left work on a Friday night. Ethereal still works, but the building is less than optimal. svn path=/trunk/; revision=1479
* Some initial changes for win32 support, but not all.Gilbert Ramirez2000-01-101-1/+6
| | | | | | | | | | | Added lots of #ifdef HAVE_*_H wrappers. Added some #defines in config.h.win32 Check for more headers in configure.in Added prototype for inet_aton() in inet_v6defs.h. Changed "BYTE" token (i.e., #define) in ascend-gramamr.y because it conflicts with a windows definition. Use HEXBYTE instead. svn path=/trunk/; revision=1448
* Move the GTK+ implementations of various UI utilities out of "util.c"Guy Harris1999-12-091-131/+1
| | | | | | | | | | | | | | | | | | | into "gtk/ui_util.c", and move the declarations of those UI utilities out of "util.h" into "ui_util.h". (The header file is in the top-level directory, rather than the "gtk" directory, because it declares window-system-independent interfaces to routines with window-system-dependent implementations.) Add to "gtk/ui_util.c" a routine to set the window and icon title. Use that routine to make the title of an Ethereal top-level window be {filename} - Ethereal if there's a capture open, and have "{filename}" be "<capture>" if it's a temporary capture file. svn path=/trunk/; revision=1255
* A "character encoding" variable is now set per packet. The existenceGilbert Ramirez1999-11-221-71/+83
| | | | | | | | | | of SNA in a packet changes the character encoding from the default ASCII to EBCDIC. The hex-printing routines in the GUI code and in the printing code convert to EBCDIC if appropriate. svn path=/trunk/; revision=1089
* Add ASCII/EBCDIC conversion to TCP Follow window. Also add Close buttonGilbert Ramirez1999-10-191-1/+101

* In "try_tempfile()", if the buffer is too short for the temporary fileGuy Harris1999-09-241-1/+5
| | | | | | | | name, stuff as much of the name as will fit into the buffer before returning an error, so the error message that gets displayed isn't completely mangled. svn path=/trunk/; revision=716
* Fix the calculation of the temporary file name length inGuy Harris1999-09-231-2/+2
| | | | | | | | | "try_tempfile()" - the first component of the name comes from the "dir" argument, so use its length, not the length of the string in the buffer it should fill in (said buffer may contain garbage, which may not *be* a C string). svn path=/trunk/; revision=705
* The Single UNIX Specification doesn't say that "mkstemp()" creates theGuy Harris1999-08-231-2/+22
| | | | | | | | | | | temporary file with mode rw-------, so we won't assume that all UNIXes will do so; instead, we set the umask to 0077 to take away all group and other permissions, attempt to create the file, and then put the umask back (puts into "try_tempfile()", called by "create_tempfile()" to create temporary files, the "umask()" calls that Gilbert put into "capture.c" to deal with the same problem). svn path=/trunk/; revision=553

* Make a "create_tempfile()" routine that constructs the template to beGuy Harris1999-08-181-1/+87
| | | | | | | | | | | | | | | | used by "mkstemp()" into a buffer supplied as an argument, trying several directories for the tempfile, in the same fashion that the BSD (and probably other) "tempnam()" routines do. Have that routine cope with temporary-file directory names that don't end with "/", as "P_tmpdir" doesn't necessarily end with "/" (and doesn't, in GNU "libc" 2.x, at least on Linux); thanks to Gilbert Ramirez for catching this one, and supplying the code to cope with that. Have the code that creates the temporary file for the "Follow TCP Stream" text use it. svn path=/trunk/; revision=507
* Added the ability to create a read-only ethereal, i.e., one thatGilbert Ramirez1999-07-091-2/+2
| | | | | | | | | | doesn't link with libpcap, so no packet captures can be made. The "--disable-pcap" option has been added to the configure script. Docs have been updated. And the string buffer size in the simple_dialog() has been doubled so that Johan's e-mail address in the "About" dialogue window doesn't get chopped off. svn path=/trunk/; revision=351
* Improve the alert boxes put up for file open/read/write errors. (SomeGuy Harris1999-06-121-70/+1
| | | | | | | | | | | | | | | | | | | | | | 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.) svn path=/trunk/; revision=310
* Capturing packets from ethereal now saves the capture in an "anonymous" ↵Gilbert Ramirez1999-04-061-1/+78
| | | | | | | | | | | buffer. That is, it's a random name chosen by tempnam(), unknown to the user. If the user decides to save that trace, he then uses File | Save to save it to a file. File | Save As lets him make a copy of his named trace file as well. I also updated my e-mail address in the various credit locations. svn path=/trunk/; revision=242
* Get rid of include of <strings.h> from "util.c", as it's not needed, andGuy Harris1999-04-051-2/+1
| | | | | | | | | change include of <strings.h> in "menu.c" to include <string.h>, the latter being the ANSI standard include file for string functions; that eliminates all use of <strings.h< so get rid of test for its existence in "configure.in" as well. svn path=/trunk/; revision=239
* Move the bitfield-decoding routines to "packet.h", along with otherGuy Harris1999-03-311-86/+1
| | | | | | | | | | | helper routines for packet dissecting, and away from "util.c", which is now all GUI-related. (Among other things, this makes life more pleasant for Gilbert Ramirez's "tethereal" stuff, although a lot more separation of GUI from other stuff needs to be done to make that - or a "curses"-based variant of Ethereal, or a variant using some other GUI toolkit - work smoothly.) svn path=/trunk/; revision=235
* Removed all references to gtk objects from packet*.[ch] files. They nowGilbert Ramirez1999-03-231-2/+4
| | | | | | | | | | reference the protocol tree with struct proto_tree and struct proto_item objects. That way, the packet decoding source code file can be used with non-gtk packet decoders, like a curses-based ethereal, e.g. I also re-arranged some of the information in packet.h to more appropriate places (like other packet-*.[ch] files). svn path=/trunk/; revision=223
