Plugins can tell when output from a process they ran was cut off

The plugin runtime's $.process.run now reports isStdoutTruncated and isStderrTruncated when output passes its 4 MiB limit

What

Plugins and hooks can start other programs with $.process.run. It keeps at most 4194304 bytes (4 MiB) of each output stream. Its result now includes two extra values:

  • isStdoutTruncated: true when the normal output was cut off
  • isStderrTruncated: true when the error output was cut off

Before this, the result held only the exit code and the two outputs, and nothing showed when text had been dropped.

Why

Plugin authors can now detect that they received only part of a program's output, instead of treating partial text as complete.

How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtIt is not clear whether the 4 MiB limit is also new or only the two truncation values are.
