Once again getting APR 1.2.7 working with OS/2 and Open Watcom, I have a
failure during testfile. The test is failing at test_ungetc. Part seems
to be the test and part the OS/2 source. In the test, the file is opened
APR_READ not APR_READ|APR_WRITE. However, I also need to know exactly
how apr_file_ungetc should actually work.
1. rewind 1 character
2. write character to stream
The file_datafile.txt contains:
This is the file data file.
As I see testfile, this is the sequence:
1. apr_file_open <file_datafile.txt>
2. apr_file_getc <returns T>
3. apr_file_ungetc <rewind 1 and write 'X'>
file_datafile.txt is now:
Xhis is the file data file.
4. apr_file_getc <returns h - is this correct?>
I ask the last because of the check:
ABTS_INT_EQUAL(tc, 'X', (int)ch);
which fails because apr_file_getc returns 'h'. Should apr_file_ungetc
rewind, write char, and rewind again ?
Last, because test_ungetc changes file_datafile.txt it causes
file_contents_equal to fail which expects file_datafile.txt to be unchanged.
