gnash 1.3.9

gnash 1.3.9

A continued bash-conformance release. Since 1.3.8, gnash has been run
against further batches of bash 5.3's own test suite and brought into
byte-for-byte agreement across debugger support, programmable completion,
functions, and array subscripts. Highlights below; a number of smaller
fidelity fixes are included.

Debugger support, DEBUG/RETURN traps, and $LINENO

• $LINENO inside a DEBUG/RETURN/ERR trap body reports the line of the
  command that fired the trap, not the trap body's own line.
• A function invoked while the DEBUG trap is running (including the trap
  handler itself) no longer spuriously fires the RETURN trap.
• The whole-body DEBUG trap reports a function's definition line, command
  substitutions run at their enclosing line, and a sourced file gets its own
  line numbering starting at 1.
• The DEBUG trap fires for each expression of an arithmetic for (( ; ; ))
  loop, and the caller builtin now matches bash (top-level form, option and
  invalid-number diagnostics).

Programmable completion

• complete -p reconstructs each specification in bash's canonical option and
  action order with correct quoting, listed in bash's hash-table walk order.
• compgen gains the setopt, shopt, enabled, and helptopic action
  generators, the -V varname and -X filterpat options, and bash's
  option/action/identifier diagnostics; compopt validates -o option names.

Functions

• Enforce FUNCNEST to cap function-call recursion.
• Reject a function name containing an unquoted $, and prefix function to a
  non-identifier name in declare -f.
• Report an error for a malformed integer-attribute assignment (i=0#4).

Arrays

• Array and associative subscripts are scanned by a single quote-aware parser,
  so a key containing ] — escaped (a[x\]y]), quoted (a["p]q"]), or from a
  substitution (a[$(cmd)]) — is handled consistently for assignment, ${...}
  reads, and compound literals.
• Implement shopt -s array_expand_once: an already-expanded array subscript is
  not re-expanded, so a command substitution left in it errors rather than
  running — closing a subscript-injection vector across printf -v, read,
  unset, assignment, arithmetic, ${a[sub]}, and test -v.
• Implement test -v / [ -v ] for scalars and array elements.
