Filesys::Smbclient and DBD::XBase

Merlin8001 has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to use DBD::XBase to read a file using a filehandle from Filesys::Smbclient.
I've gotten this far:
#!/user/bin/perl use Filesys::SmbClient; use XBase; my $smb = new Filesys::SmbClient(username=> "MYUSER", password=> "**********", workgroup=> "LAZYGROUP"); my $smbfilehandle = $smb->open("smb://myserver/myshare/databases/readt +histable.dbf"); XBase::Base::SEEK_VIA_READ(0); my $thistable = new XBase("-", 'fh' => $smbfilehandle, 'ignorememo' => + 1); $thistable->dump_records("fs" => " | ", "rs" => " <-+\n", "fields" => [ "location", "filename" ]); $smb->closedir($thistable);
I get this error:
Can't call method "autoflush" without a package or objectt reference a +t /usr/lib/perl5/vendor_perl/5.8.1/XBase/Base.pm line 106.

the problem seems to be that the filehandle for SmbClient doesn't have an autoflush function
the docs for Filesys::Smbclient mention using tie() but I'm having trouble figuring out if that's something related to my problem.
suggestions?

    The OP and I worked on this one on IRC... Our main problems were these:

    • $smbfilehandle isn't a "real" filehandle, it's a number that SmbClient uses to track its open files
    • XBase uses the value of the 'fh' parameter like an object, so we need an IO::Handle for this
    • Filesys::SmbClient doesn't provide a tied object like when using IO::Handle, so we must either use special read calls, or only builtins
    • It's possible to make a subclass for XBase that knows how to work with SmbClient, but that's quite a bit of work.
    I think using mounted locations is the simplest solution, but in case any monk has an idea... it would be appreciated.

      Had something like this pop up last week trying to read a remote file-based 'database'. We ended up going the most expedient route by just bringing over the files ( < 100k, total). SMB w/XBase we left for a time when we had time.

      I know it's not a solution to your problem, but it does work (if a tad on the inelegant side).

      Well, that's my $.02 worth. No, for refunds you'll have to check our customer service department.
