2004-02-27First attempt at "bitwise AND" display filter operator.Olivier Biot1-1/+23
Document how a display operator can be added. svn path=/trunk/; revision=10250
2003-12-06From Olivier BiotGilbert Ramirez1-1/+2
New "matches" operater in display filter language. Uses PCRE. If a "matches" operator is found in a dfilter while libpcre has not been used to build the binary, then an exception is thrown after using dfilter_fail() to set an apporporiate error message. svn path=/trunk/; revision=9182
2003-11-25fvalue_free() is one of the most called functions.Ronnie Sahlberg1-2/+2
This function is also very small, so small that teh overhead for the actual function call and return is likely to be a significant part of its execution time. change it into a macro and make it thus slightly faster by eliminating the function call overhead. svn path=/trunk/; revision=9083
2003-08-27Add a "contains" operator for byte-strings, strings, and tvbuffs (protocols).Gilbert Ramirez1-3/+4
The search uses a naive approach; more work is required to add a Boyer-Moore Search algorithm. svn path=/trunk/; revision=8280
2003-07-31Give FT_IPv4 val_repr_len and val_to_repr methods, and use them forGuy Harris1-3/+18
generating display filters from FT_IPv4 fields. svn path=/trunk/; revision=8110
2003-07-25Add to the fundamental types passed between the scanner and the parser.Gilbert Ramirez1-4/+6
Besides "STRING", there is now "UNPARSED_STRING", where the distinction is that "STRING" was a double-quoted string and "UNPARSED_STRING" is just a sequence of characters that the scanner didn't know how to scan/parse, so it's up to the Ftype to parse it. This gives us more flexibility and prepares the dfilter parsing engine for the upcoming addition of the "contains" operator. In the process of doing this, I also re-did the double-quoted string support in the scanner, so that instead of the naively-simple support we used to have, double-quoted strings now can have embedded dobule-quotes, embedded octal sequences, and embedded hexadecimal sequences: "\"" embedded double-quote "\110" embedded octal "\x48" embedded hex Enhance the dfilter unit test script to be able to run a single collection of tests instead of having to run all of them all the time. svn path=/trunk/; revision=8083
2003-02-08Provide a way for ftype modules to provide a string representationGilbert Ramirez1-1/+3
of their value. Provide such a method for FT_BYTES, FT_UINT_BYTES, and FT_ETHER. Have proto_alloc_dfilter_string() use the new methods. This is part of a movement of ftype-related code out of proto.c and into the ftype code. The immediate effect is that generated display filters for long byte sequences don't incorrectly have trailing periods ("...") to indicate continuation. svn path=/trunk/; revision=7100
2002-08-28Removed trailing whitespaces from .h and .c files using theJörg Mayer1-4/+4
winapi_cleanup tool written by Patrik Stridvall for the wine project. svn path=/trunk/; revision=6116
2002-02-05"log" is a name that belongs to the ANSI C89 standard; it refers to aGuy Harris1-7/+10
function that computes the natural logarithm of a double. Using it as the name of a pointer to a routine to do logging can cause namespace collisions; in fact, it *does* cause them on AIX. Rename the function argument to "logfunc". svn path=/trunk/; revision=4700
2002-01-21Include files from the "epan" directory and subdirectories thereof withGuy Harris1-3/+3
"epan/..." pathnames, so as to avoid collisions with header files in any of the directories in which we look (e.g., "proto.h", as some other package has its own "proto.h" file which it installs in the top-level include directory). Don't add "-I" flags to search "epan", as that's no longer necessary (and we want includes of "epan" headers to fail if the "epan/" is left out, so that we don't re-introduce includes lacking "epan/"). svn path=/trunk/; revision=4586
2001-07-13From Joerg Mayer:Guy Harris1-1/+4
* gcc 3.0 warning fixes: - text2pcap.c: The number of characters to scan should probably not be 0 - wiretap/csids.c: using preincrement on a variable used on both sides of an assignment might be undefined by the C99(?) standard * turn on additional warnings for epan and wiretap too - epan/configure.in - wiretap/configure.in * Fix some warnings (missing includes, signed/unsigned, missing initializers) found by turning on the warnings - all other files :-) svn path=/trunk/; revision=3709
2001-06-23"index()" is non-standard, and MSVC++ 6.0 complained about it; the ANSIGuy Harris1-4/+3
C standard has "strchr()" instead, so use it. svn path=/trunk/; revision=3602
2001-06-22Support CIDR notation in IPv4 address filtering.Gilbert Ramirez1-5/+66
svn path=/trunk/; revision=3601
2001-03-02Get rid of unused method from ftypes structure.Gilbert Ramirez1-11/+1
svn path=/trunk/; revision=3093
2001-02-01Grumble, grumble. I forgot to add the license comment at the topGilbert Ramirez1-0/+22
of these files. svn path=/trunk/; revision=2968
2001-02-01Create a more modular type system for the FT_* types. Put themGilbert Ramirez1-0/+114
into epan/ftypes. Re-write display filter routines using Lemon parser instead of yacc. Besides using a different tool, the new grammar is much simpler, while the display filter engine itself is more powerful and more easily extended. Add dftest executable, to test display filter "bytecode" generation. Add option to "configure" to build dftest or randpkt, both of which are not built by default. Implement Ed Warnicke's ideas about dranges in the new display filter and ftype code. Remove type FT_TEXT_ONLY in favor of FT_NONE, and have protocols registered as FT_PROTOCOL. Thus, FT_NONE is used only for simple labels in the proto tree, while FT_PROTOCOL is used for protocols. This was necessary for being able to make byte slices (ranges) out of protocols, like "frame[0:3]" Win32 Makefile.nmake's will be added tonight. svn path=/trunk/; revision=2967
