>Description:
I discovered this problem on my OS X machine, and I am just trying to pass the
information upstream as I see it also exists in the FreeBSD source code.
When using uudecode, if an improper character is detected, the error message
that is printed does not match the actual error. The problem is that the IS_DEC
macro allows character 32-96 inclusive. But the error message says that the
allowed characters are 33-96. This caused me some trouble in diagnosing a
problem with an external uuencode system.
#define IS_DEC(c) ( (((c) - ' ') >= 0) && (((c) - ' ') <= 077 + 1) )
#define OUT_OF_RANGE do { \
warnx("%s: %s: character out of range: [%d-%d]", \
infile, outfile, 1 + ' ', 077 + ' ' + 1); \
As you can see, the error message includes a 1 + ' ', which this IS_DEC macro
does not have.
>How-To-Repeat:
This only occurs with an improperly formatted file. Here is a simple way to
improperly format a file.
$ echo "This is a test" >temp.txt
$ uuencode -o temp.uu temp.txt temp.txt
$ cat temp.uu
begin 644 temp.txt
/5&AI<R!I<R!A('1E<W0*
`
end
$ sed 's/^`$//' temp.uu | uudecode
uudecode:
input file: stdin
encoded file: temp.txt
character out of range: [33-96]
>Fix:
#define OUT_OF_RANGE do { \
warnx("%s: %s: character out of range: [%d-%d]", \
infile, outfile, ' ', 077 + ' ' + 1); \
