      Don't truncate traceEvents to 512 bytes (#8309) · a82364c9
      thomie authored
      Summary:
      Don't call postLogMsg to post a user msg, because it truncates messages to
      512 bytes.
      
      Rename traceCap_stderr and trace_stderr to vtraceCap_stderr and trace_stderr,
      to signal that they take a va_list (similar to vdebugBelch vs debugBelch).
      
      See #3874 for the original reason behind traceFormatUserMsg.
      
      See the commit msg in #9395 (d360d440) for a discussion about using
      null-terminated strings vs strings with an explicit length.
      
      Test Plan:
      Run `cabal install ghc-events` and inspect the result of `ghc-events show` on
      an eventlog file created with `ghc -eventlog Test.hs` and `./Test +RTS -l`,
      where Test.hs contains:
      
      ```
      import Debug.Trace
      main = traceEvent (replicate 510 'a' ++ "bcd") $ return ()
      ```
      
      Depends on D655.
