tracetool: Forbid newline character in event format

2024-06-10T17:05:27Z

Events aren't designed to be multi-lines. Multiple events can be used instead. Prevent that format using multi-lines by forbidding the newline character.

Now we no longer have vcpu controlled trace events we can excise the code that allows us to query its status.

trace: remove vcpu_id from the TraceEvent structure

This does involve temporarily stubbing out some helper functions before we excise the rest of the code.

tracetool: use relative paths for '#line' preprocessor directives

2023-04-24T17:53:44Z

The event filename is an absolute path. Convert it to a relative path when writing '#line' directives, to preserve reproducibility of the generated output when different base paths are used.

On Fedora 36, with lttng-ust 2.13.1, compilation fails with: In file included from trace/trace-ust-all.h:49085, from trace/trace-ust-all.c:13: /usr/include/lttng/tracepoint-event.h:67:10: error: #include expects "FILENAME" or 67 | #include LTTNG_UST_TRACEPOINT_INCLUDE | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ In lttng-ust commit 41858e2b6e8 ("Fix: don't do macro expansion in tracepoint file name") from 2012, starting from lttng-ust 2.1, the API was changed to expect TRACEPOINT_INCLUDE to be defined as a string. In lttng-ust commit d2966b4b0b2 ("Remove TRACEPOINT_INCLUDE_FILE macro"), in 2021, the compatibility macro was removed. Use the "new" API from 2012, and bump the version requirement to 2.1 to fix compilation with >= 2.13.

tracing: excise the tcg related from tracetool

Now we have no TCG trace events and no longer handle them in the code we can remove the handling from the tracetool to generate them. vcpu tracing is still available although the existing syscall event is an exercise in redundancy (plugins and -strace can also get the information).
