-Subject: [PATCH] gconv: Do not emit spurious NUL character in ISO-2022-JP-3
- (bug 28524)
-
-Bugfix 27256 has introduced another issue:
-In conversion from ISO-2022-JP-3 encoding, it is possible
-to force iconv to emit extra NUL character on internal state reset.
-To do this, it is sufficient to feed iconv with escape sequence
-which switches active character set.
-The simplified check 'data->__statep->__count != ASCII_set'
-introduced by the aforementioned bugfix picks that case and
-behaves as if '\0' character has been queued thus emitting it.
-
-To eliminate this issue, these steps are taken:
-* Restore original condition
-'(data->__statep->__count & ~7) != ASCII_set'.
-It is necessary since bits 0-2 may contain
-number of buffered input characters.
-* Check that queued character is not NUL.
-Similar step is taken for main conversion loop.
-
-Bundled test case follows following logic:
-* Try to convert ISO-2022-JP-3 escape sequence
-switching active character set
-* Reset internal state by providing NULL as input buffer
-* Ensure that nothing has been converted.
