static

Check that the budget is measured with fr_sbuff_used_total(), not fr_sbuff_used()

fr_sbuff_shift() moves data out of the buffer and adds the amount which fr_sbuff_start() can no longer account for to fr_sbuff_shifted(). So fr_sbuff_used_total() does not change across a shift, while fr_sbuff_used() shrinks. See test_shift_used_accounting().

fr_sbuff_out_unescape_until() re-runs fr_sbuff_marker_update_end() after every extension, and an extension is exactly when a shift happens. Measuring the budget with fr_sbuff_used() would therefore reset the budget on every shift, and the operation could copy more than it was allowed to.

The budget below is larger than fr_sbuff_used() but smaller than fr_sbuff_used_total(), so the two accessors give different answers.

Check that a hex or octal escape sequence cannot consume more input than "len" allows.

fr_sbuff_out_unescape_until() bounds the input it consumes with a marker placed "len" bytes ahead of the start. The escape sequences are the one place where the input is advanced by more than a byte at a time, so they are the one place where the marker can be stepped over.

An escape sequence which does not fit within "len" is not a complete escape sequence, and is copied out as-is. That is the same thing which happens to an incomplete escape sequence at the end of the input.
