2017-06-05Allow bigger snapshot lengths for D-Bus captures.Guy Harris1-1/+1
Use WTAP_MAX_PACKET_SIZE_STANDARD, set to 256KB, for everything except for D-Bus captures. Use WTAP_MAX_PACKET_SIZE_DBUS, set to 128MB, for them, because that's the largest possible D-Bus message size. See https://bugs.freedesktop.org/show_bug.cgi?id=100220 for an example of the problems caused by limiting the snapshot length to 256KB for D-Bus. Have a snapshot length of 0 in a capture_file structure mean "there is no snapshot length for the file"; we don't need the has_snap field in that case, a value of 0 mean "no, we don't have a snapshot length". In dumpcap, start out with a pipe buffer size of 2KB, and grow it as necessary. When checking for a too-big packet from a pipe, check against the appropriate maximum - 128MB for DLT_DBUS, 256KB for everything else.

2016-04-03Make the Flex scanners and YACC parser in libraries reentrant.Guy Harris1-1/+1
master-branch libpcap now generates a reentrant Flex scanner and Bison/Berkeley YACC parser for capture filter expressions, so it requires versions of Flex and Bison/Berkeley YACC that support that. We might as well do the same. For libwiretap, it means we could actually have multiple K12 text or Ascend/Lucent text files open at the same time. For libwireshark, it might not be as useful, as we only read configuration files at startup (which should only happen once, in one thread) or on demand (in which case, if we ever support multiple threads running libwireshark, we'd need a mutex to ensure that only one file reads it), but it's still the right thing to do. We also require a version of Flex that can write out a header file, so we change the runlex script to generate the header file ourselves. This means we require a version of Flex new enough to support --header-file. Clean up some other stuff encountered in the process.

2016-03-27Pull the invocation of the Lex scanner into common code.Guy Harris1-2/+1
Instead of text_import_setup() and text_import_cleanup() routines, and the actual scanner invocation being done in the dialog box, have a text_import() routine that does all the work.

2014-05-09Refactor WiretapMichael Mann1-1/+1
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>
