[Octave-bug-tracker] [bug #63968] fwrite writes incorrect number of bytes

[Arun Giridhar]

Follow-up Comment #2, bug #63968 (project octave):

I ran your code and this is the output I got with both the unpatched and
patched versions, so this looks like good news?


octave:1> test_63968
Writing File
Wrote 16386810 bytes

File Pointer 16386810

Write took 95.057924 seconds

Reading File
Read took 0.087963 seconds

Read 16386810 bytes

File Pointer 16386810

Reading File
Read took 141.914758 seconds

Read 16386810 bytes



Then to double-check, I set the encoding to latin1, and sure enough I got the
error:


octave:1> __mfile_encoding__ ("latin1")
octave:2> __mfile_encoding__
ans = latin1
octave:3> test_63968
Writing File
Wrote 16386810 bytes

File Pointer 16277485

Write took 99.510554 seconds

Reading File
Read took 0.088034 seconds

Read 16277511 bytes

File Pointer 16277511

Reading File

File Pointer 16277511

error: Invalid Read
error: called from
    test_63968 at line 49 column 9


This is identical to the other two bugs, so I'll leave this closed as a
duplicate but if you want a workaround before 8.2.0 is released, please set
your encoding to UTF-8. You can do that in the Octave GUI, or from the command
prompt you can run


__mfile_encoding__ ("utf-8")
