Testing on a Mac OS machine, the I found it consistently prints
out 8192 characters. This should be immediately recognizable as a
magic number (8k or 2**13). This tells me that SSH::Command (or
the underlying libssh2 library) has an 8k buffer and once it is
full, it no longer returns any data. Looking at the code for
SSH::Command, I see the following function:
# Execute command and get answer as text
sub execute_command_and_get_answer {
my ($ssh2, $command) = @_;
my $chan = $ssh2->channel();
$chan->exec($command);
$chan->read(my $result, 102400);
chomp $result; # remove \n on string tail
return $result;
}
This looks like a fixed read (albeit a longer one that I expected,
so there is probably a fixed buffer in libssh2 too), so that is
likely the problem. Changing the function to read until an end of
file is detected:
sub execute_command_and_get_answer {
my ($ssh2, $command) = @_;
my $chan = $ssh2->channel();
$chan->exec($command);
my $result = "";
until ($chan->eof) {
$chan->read(my $buf, 4_096);
$result .= $buf;
}
chomp $result; # remove \n on string tail
return $result;
}
seems to fix the problem. I am filling a bug against the module,
but given that the last release was in 2009 and the most current
version is less than 1.0 (0.7), you may want to find a different
module to use.
