4Subject: [PATCH] gconv: Do not emit spurious NUL character in ISO-2022-JP-3
5 (bug 28524)
6
7Bugfix 27256 has introduced another issue:
8In conversion from ISO-2022-JP-3 encoding, it is possible
9to force iconv to emit extra NUL character on internal state reset.
10To do this, it is sufficient to feed iconv with escape sequence
11which switches active character set.
12The simplified check 'data->__statep->__count != ASCII_set'
13introduced by the aforementioned bugfix picks that case and
14behaves as if '\0' character has been queued thus emitting it.
15
16To eliminate this issue, these steps are taken:
17* Restore original condition
18'(data->__statep->__count & ~7) != ASCII_set'.
19It is necessary since bits 0-2 may contain
20number of buffered input characters.
21* Check that queued character is not NUL.
22Similar step is taken for main conversion loop.
23
24Bundled test case follows following logic:
25* Try to convert ISO-2022-JP-3 escape sequence
26switching active character set
27* Reset internal state by providing NULL as input buffer
28* Ensure that nothing has been converted.
