2016-07-22Minimize allocations for frame tvbuffs and Buffers.Gerald Combs1-4/+10
Try to minimize the number of times we allocate memory for Buffers and Buffer data.

2016-02-18Don't add the wiretap directory to the list of include directories.Guy Harris1-1/+1
If you include something from the wiretap directory, always precede it with wiretap/. Fix some includes of files in the top-level directory to use a path relative to the current directory, not relative to the wiretap directory. This makes it a bit clearer what's being included.

2015-02-11Combine SSE and pre-compiled patterns for faster pbrkHadriel Kaplan1-2/+2
This combines the SSE4.2 instructions usage, with pre-compiled pattern searching usage, for a faster pbrk search method. Testing against large files of HTTP and SIP, there is about a 5% performance improvement by using pre-"compiled" patterns for guint8_pbrk() instead of passing it the search string and having it build the match array every time. Similar to regular expressions, "compiling" the pattern match array in advance only once and using the "compiled" patterns for the searches is faster than compiling it every time.

2014-08-02Rename buffer_ routines to ws_buffer_ to avoid name collisions.Guy Harris1-5/+5
In particular, epan/wslua/lrexlib.c has its own buffer_ routines, causing some linker warnings on some platforms, as reported in bug 10332. (Not to be backported to 1.12, as that would change the API and ABI of libwsutil and libwiretap. We should also make the buffer_ routines in epan/wslua/lrexlib.c static, which should also address this problem, but the name change avoids other potential namespace collisions.)

2014-05-23Revert "Allow wtap_read() and wtap_seek_read() to return non-packet records."Guy Harris1-1/+1
This reverts commit c0c480d08c175eed4524ea9e73ec86298f468cf4. A better way to do this is to have the record type be part of struct wtap_pkthdr; that keeps the metadata for the record together and requires fewer API changes. That is in-progress.

This is the first step towards implementing the mechanisms requestd in bug 8590; currently, we don't return any records other than packet records from libwiretap, and just ignore non-packet records in the rest of Wireshark, but this at least gets the ball rolling.

2014-05-09Refactor WiretapMichael Mann1-8/+8
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>
2014-03-27Fix bug9931 'Encapsulated ethernet packets sometimes show invalid FCS'Hadriel Kaplan1-0/+2
This fixes part-1 of bug9931: the uninitialized use of a wtap_pkthdr struct. The second part of the bug deals with dissectors calling the Ethernet dissector for ecnapsulated Ethernet packets but using the wrong dissector handle to do so. That's unrelated to the issue this commit addresses, so I'm splitting them up.

2014-01-08TFShark (Terminal Fileshark) v.001. Bug 9607 ↵Michael Mann1-0/+68
(https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9607) This is a VERY PRELIMINARY version of tfshark. It's an attempt to jumpstart FileShark and its architecture. Right now it's mostly just a very stripped down version of tshark with all of the necessary build modifications (including now building filetap library since tfshark depends on it) This code has helped me identify what I believe to be all of the necessary layers for a complete fileshark architecture. And those layers will slowly be added in time (patches always welcome!). svn path=/trunk/; revision=54646
