Bug #: 13518
Summary: iconv truncates input with //IGNORE
Product: glibc
Version: 2.14
Status: NEW
Severity: normal
Priority: P2
Component: libc
AssignedTo: drepper.fsp@gmail.com
ReportedBy: ezyang@mit.edu
Classification: Unclassified
iconv seems to truncate inputs at around 8157 bytes if they contain invalid
characters for the target set, even if IGNORE is specified.
Steps to reproduce:
1. Download iconv.html
ezyang@javelin:~$ wget http://www.oppcharts.com/iconv.html
2. Attempt to convert UTF-8 to iso-8859-1//IGNORE
Expected behavior (from libiconv-1.14):
ezyang@javelin:~/Dev/glibc/build$ ~/Desktop/libiconv-1.14/src/iconv_no_i18n -f
utf-8 -t iso-8859-1//IGNORE ~/iconv.html | wc -c
15312
Actual behavior (from latest Git glibc-2.14-567-ga4647e7):
ezyang@javelin:~/Dev/glibc/build$ ./testrun.sh iconv/iconv_prog -f utf-8 -t
iso-8859-1//IGNORE ~/iconv.html | wc -c
iconv/iconv_prog: illegal input sequence at position 8168
8157

Alpha, followed by a lot of x's
Here's a better, more minimal test-case.
ezyang@javelin:~$ Dev/glibc/build/testrun.sh Dev/glibc/build/iconv/iconv_prog
-f utf-8 -t ascii//IGNORE < test.txt | wc -c

The iconv program cannot be used with the magic //IGNORE suffix. You have to
use the -c parameter.

I think there still is a bug here. If //IGNORE is not supported by iconv_prog,
the behavior between -t with IGNORE and -c should be the same. However, this is
not the case:
ezyang@javelin:~$ Dev/glibc/build/testrun.sh Dev/glibc/build/iconv/iconv_prog
-f utf-8 -t ascii//IGNORE < test.txt | wc -c
Dev/glibc/build/iconv/iconv_prog: illegal input sequence at position 8161
8159
ezyang@javelin:~$ Dev/glibc/build/testrun.sh Dev/glibc/build/iconv/iconv_prog
-f utf-8 -t ascii < test.txt | wc -c
Dev/glibc/build/iconv/iconv_prog: illegal input sequence at position 0
0
For reference, here is iconv running with an invalid extra flag:
ezyang@javelin:~$ Dev/glibc/build/testrun.sh Dev/glibc/build/iconv/iconv_prog
-f utf-8 -t ascii//FOOBAR < test.txt | wc -c
Dev/glibc/build/iconv/iconv_prog: illegal input sequence at position 0

OK, I think I understand the underlying issue better. I'll file a new bug.
