2022-12-30dftest: Fix command-line argument parsingJoão Valverde1-24/+35
Expressions that start with hyphen clash with command-line options. In that case we need to pass "--" to dftest to stop processing options. Fix the test suite to do this. Fixes failures with dftest and expressions like: -2 == tcp.port Replace the GLib option parser with getopt while at it. The GLib API is nice but isn't a good fit for this utility and the code appears to be inconsistent on whether "--" is left in the argv or not.

Remove duplicate location struct by adding a new header. Pass around a structure instead of a pointer.

When we are just testing code to see if it compiles performing optimizations is wasteful. Add an option to disable them.
2022-11-28dfilter: Return an error object instead of stringJoão Valverde1-6/+6
Return an struct containing error information. This simplifies the interface to more easily provide richer diagnostics in the future. Add an error code besides a human-readable error string to allow checking programmatically for errors in a robust manner. Currently there is only a generic error code, it is expected to increase in the future. Move error location information to the struct. Change callers and implementation to use the new interface.

2022-04-11dfilter: Handle missing error location more gracefullyJoão Valverde1-3/+5
If we don't have an offset, don't print anything with underline. Also it can underline filters using macros correctly now. $ tshark -Y 'ip and ${private_ipv4:ip.sr}' -r /dev/null tshark: Left side of "==" expression must be a field or function, not "ip.sr". ip and ip.sr == 192.168.0.0/16 or ip.sr == 172.16.0.0/12 or ip.sr == 10.0.0.0/8 ^~~~~
2022-04-10dfilter: Add location tracking to scanner and use it to report errorsJoão Valverde1-6/+42
Add location tracking as a column offset and length from offset to the scanner. Our input is a single line only so we don't need to track line offset. Record that information in the syntax tree. Return the error location in dfilter_compile(). Use it in dftest to mark the location of the error in the filter string. Later it would be nice to use the location in the GUI as well. $ dftest "ip.proto == aaaaaa and tcp.port == 123" Filter: ip.proto == aaaaaa and tcp.port == 123 dftest: "aaaaaa" cannot be found among the possible values for ip.proto. ip.proto == aaaaaa and tcp.port == 123 ^~~~~~
2022-04-05dfilter: Print syntax tree using dftest + format enhancementsJoão Valverde1-3/+7
Add argument to dfilter_compile_real() to save syntax tree text representation. Use it with dftest to print syntax tree. Misc debug output format improvements.
2022-04-04wsutil: Add configuration namespaces.Gerald Combs1-5/+5
Rename init_progfile_dir to configuration_init. Add an argument which specifies our configuration namespace, which can be "Wireshark" (default) or "Logwolf".

2022-01-01Revert "epan: Initialize wiretap"João Valverde1-0/+9
This reverts commit c15f2aadc1aef3f4855c682ff7f686d5f63088cb. Crashes on exit. Needs more work. Fixes #17821.
2021-11-27epan: Initialize wiretapJoão Valverde1-9/+0
Clients of libwireshark should not be required to initialize explicitly wiretap, if they don't use it themselves.
2021-09-29dftest: Don't use quotes to output filterJoão Valverde1-1/+1
Using quotes is confusing because they are difficult to distinguish from the actual filter expression itself. Quotes are unnecessary anyway because whitespace is not significant (except inside brackets).
2021-06-26wslog: Check environment initialization for errorsJoão Valverde1-3/+3
Initialiaze the cmdarg error stream earlier. Dumpcap also needs to know earlier if it is running in capture child mode.
2021-06-21wslog: Check if we are initialized and add missing initsJoão Valverde1-0/+7
Instead of receiving the program name from GLib, pass it explicitly to ws_log_init() instead and use that to initialize the GLib program name. ws_log_parse_args() will now exit the program when it encounters an argument error if exit_failure >= 0.
2021-03-15Add more error-reporting routines that call through a function pointer.Guy Harris1-36/+25
Have routines to report capture-file errors, using libwireshark error codes and strings, that call through a pointer, so they can pop up dialogs in GUI apps, print a message to the standard error on command-line apps, and possibly do something different on server programs. Have init_report_message() take a pointer to structure containing those function pointers, rather than the function pointers themselves, as arguments. Make other API changes to make that work.
2021-02-19wiretap: eliminate two WTAP_FILE_TYPE_SUBTYPE_ values.Guy Harris1-0/+5
Eliminate WTAP_FILE_TYPE_SUBTYPE_ERF and WTAP_FILE_TYPE_SUBTYPE_SYSTEMD_JOURNAL - instead, fetch the values by name, using wtap_name_to_file_type_subtype(). This requires that wtap_init() be called before epan_init(); that's currently the case, but put in comments to indicate why it must continue to be the case.
2020-07-06Windows: Set our locale to ".UTF-8".Gerald Combs1-1/+8
In each of our executables we were calling "setlocale(LC_ALL, "")" at startup. This told Windows that output was encoded using the current system code page. Unless the code page was 65001 (UTF-8), this was a lie. We write UTF-8 to stdout and stderr, so call "setlocale(LC_ALL, ".UTF-8)" at startup on Windows. This lets the CRT translate our output correctly in more cases. Clarify and expand the OUTPUT section in the tshark man page.

2017-12-14Refactor plugin registration and loadingJoão Valverde1-9/+0
Put different types of plugins (libwiretap, libwireshark) in different subdirectories, give libwiretap and libwireshark init routines that load the plugins, and have them scan the appropriate subdirectories so that we don't even *try* to, for example, load libwireshark plugins in programs that only use libwiretap. Compiled plugins are stored in subfolders of the plugin folders, with the subfolder name being the Wireshark minor version number (X.Y). There is another hierarchical level for each Wireshark library (libwireshark, libwscodecs and libwiretap). The folder names are respectively plugins/X.Y/{epan,codecs,wiretap}. Currently we only distribute "epan" (libwireshark) plugins.
