2014-07-04Move utility routines for capturing into a libcaputils static library.Guy Harris1-2/+2
Some of those routines are used only in dumpcap; others are used in TShark and Wireshark as well. Change-Id: I9d92483f2fcff57a7d8b6bf6bdf2870505d19fb7 Reviewed-on: https://code.wireshark.org/review/2841 Reviewed-by: Guy Harris <guy@alum.mit.edu>
2014-07-03Include "capture-pcap-util.h" even if we don't have libpcap.Guy Harris1-1/+2
The routines to get libpcap version information just say "no pcap here" if we don't have it, so they're called regardless of whether we were compiled with it.

Only print to the standard output, and only give the version information, if a "print help" command-line option is specified. Otherwise, leave out the version information, and print to the standard error. Leave out the copyright information; it's extra cruft, and http://www.gnu.org/prep/standards/html_node/_002d_002dhelp.html doesn't say anything about it (and bash, at least, doesn't print it).

For Wireshark, say "Wireshark", not "wireshark". For other programs, put "(Wireshark)" after the program name, as per http://www.gnu.org/prep/standards/html_node/_002d_002dversion.html ("If the program is a subsidiary part of a larger package, mention the package name in parentheses, like this").

Add a routine get_ws_vcs_version_info() that, for builds from a tree checked out from Wireshark's version control system, returns a string that includes both the Wireshark version number and an indication of what particular VCS version was checked out, and just returns Wireshark's version number for other builds. Use that routine rather than manually gluing VERSION and the Git version number together.

Start of refactoring Wiretap and breaking structures down into "generally useful fields for dissection" and "capture specific". Since this in intended as a "base" for Wiretap and Filetap, the "wft" prefix is used for "common" functionality. The "architectural" changes can be found in cfile.h, wtap.h, wtap-int.h and (new file) wftap-int.h. Most of the other (painstaking) changes were really just the result of compiling those new architecture changes. bug:9607 Change-Id: Ife858a61760d7a8a03be073546c0e7e582cab2ae Reviewed-on: https://code.wireshark.org/review/1485 Reviewed-by: Michael Mann <mmann78@netscape.net>
2014-04-12Get rid of more tvb_get_nstringz* calls.Guy Harris1-1/+3
Add an FT_STRINGZPAD type, for null-padded strings (typically fixed-length fields, where the string can be up to the length of the field, and is null-padded if it's shorter than that), and use it. Use IS_FT_STRING() in more cases, so that less code needs to know what types are string types. Add a tvb_get_stringzpad() routine, which gets null-padded strings. Currently, it does the same thing that tvb_get_string_enc() does, but that might change if we don't store string values as null-terminated strings.

2014-03-21Fix Bug 9903: 'Clicking reload-file ignores selected file format reader'Hadriel Kaplan1-0/+1
There's a relatively new feature in 1.11.3 to select a specific file format reader, instead of relying on magics or heuristics. If you select a file reader and open a file, open it, and then click the reload-file button or go to View->Reload or press the ctrl-R keymap, the file is reloaded but using the magic/heuristics again instead of the file format reader you previously chose. Likewise, the Lua relaod() function has the same issue (which is how I found this problem). I have tested this change by hand, using a Lua script, but I didn't add it to the testsuite because I need another change for my test script to work correctly. (an enhancement rather than a bug fix, which I'll submit separately) Change-Id: I48c2d9ea443e37fd9d41be43d6b6cd5a866d5b01 Reviewed-on: https://code.wireshark.org/review/764 Reviewed-by: Anders Broman <a.broman58@gmail.com>

2013-09-29Replace some val_to_str calls with the equivalent val_to_str_const calls (andEvan Huus1-8/+8
implement rval_to_str_const to do this). The format-strings didn't have any parameter specifiers in them, so they were clearly never used (or they would have blown up) but still a bug. This is one of the first steps towards converting val_to_str and friends to wmem. I'm honestly not sure what the best approach is for the API in this case: the vast majority of usage is within dissectors, so just hard-coding packet scope (the way they currently hard-code ep_ scope) doesn't look terrible, but there are *some* uses in taps and other places that will need to be converted to something else if we go that route. Adding a wmem_pool parameter just for the uncommon case seems a bit like overkill, though perhaps it is the right thing to do. svn path=/trunk/; revision=52264

Change some data types to avoid those implicit conversion warnings. When assigning a constant to a float, make sure the constant isn't a double, by appending "f" to the constant. Constify a bunch of variables, parameters, and return values to eliminate warnings due to strings being given const qualifiers. Cast away those warnings in some cases where an API we don't control forces us to do so. Enable a bunch of additional warnings by default. Note why at least some of the other warnings aren't enabled. randpkt.c and text2pcap.c are used to build programs, so they don't need to be in EXTRA_DIST. If the user specifies --enable-warnings-as-errors, add -Werror *even if the user specified --enable-extra-gcc-flags; assume they know what they're doing and are willing to have the compile fail due to the extra GCC warnings being treated as errors. svn path=/trunk/; revision=46748
