2018-02-16Use DIAG_OFF_FLEX/DIAG_ON_FLEX more consistently.Guy Harris1-1/+11
Add warning C4267 (size_t to int conversion) with MSVC to DIAG_OFF_FLEX. Addd -Wshorten-64-to-32 with Clang and GCC to DIAG_OFF_FLEX. Don't explicitly use #pragma to turn off warnings; use DIAG_OFF_FLEX for all of them. If we use DIAG_OFF_FLEX, use DIAG_ON_FLEX, even if we have no section of entirely included code at the end.

2016-12-02Include config.h at the very beginning of all Flex scanners.Guy Harris1-2/+5
That way, if we #define anything for large file support, that's done before we include any system header files that either depend on that definition or that define it themselves if it's not already defined.

2016-09-16Don't pick up junk from an unset error-number variable.Guy Harris1-4/+4
Keep the actual error code and pointer-to-error-string in the scanner state, rather than pointers to the variables passed in to us. Initialize them to 0 and NULL, respectively. That way, when the actual scanner routine returns, we don't check for an error by looking at the error variable pointed to by our argument, which might not have been set by the scanner and might have stack junk in it, we look at a structure member we set to 0 before the scan.

2016-04-03Make the Flex scanners and YACC parser in libraries reentrant.Guy Harris1-45/+81
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.

2015-11-06Don't include io.h in Flex scanners - they're not interactive.Guy Harris1-5/+1
We don't have any Flex scanners that support an interactive command-line interface, so none of our scanners are, or need to be, interactive. Mark text2pcap's scanner as not interactive. That means none of our scanners should call isatty(), so they don't have any need to include <io.h> on Windows; remove that include from the Lucent/Ascent text capture scanner. Update a comment to reflect that what matters isn't whether we can read from a terminal or whether we actually do so, what matters is whether they read *interactively* from a terminal (if you want to run text2pcap reading from the standard input and type at it, be my guest).
