#17 Perl error message about an empty string

[Bram]

kpcli 2.8 gives me the following message now and then:

Can't use string ("") as a HASH ref while "strict refs" in use at /usr/local/bin/kpcli line 1895.

Steps to reproduce:

kpcli:/> show Internet/test1
 Path: /Internet/
Title: test1
Uname: test
 Pass: test
  URL: test
Notes: 
Can't use string ("") as a HASH ref while "strict refs" in use at /usr/local/bin/kpcli line 1895.

Using Perl v5.14.2.

Any ideas?

Could you upload a sample KeePass file that this happens on? Thanks.

Please also send the output of a vers command; like this:

kpcli-2.8:/> vers

Oops... this also triggers a file changed warning!

It also looks like attaching fails:

kpcli:/> attach Internet/test

Attaching fails...

Bests,

I see the problem now. File::KeePass did not introduce support for attachments until much, much later than the version that you are using (v0.03). I should have accounted for that fact in the code, but I failed to. Honestly, File::KeePass v0.03 is so old at this point (December 2010) that I probably should just declare it unsupported by kpcli.

Later, I may look into patching kpcli to not fail this way with v0.03 of File::KeePass, but for now, if you'll upgrade File::KeePass (preferably to 2.03) then I believe that your problem will go away: http://search.cpan.org/~rhandom/File-KeePass-2.03/

I would like to hear any reasons why upgrading File::KeePass is difficult for you, if it is.

Sincerely,

Lester

Ok, the message is gone after upgrading File:Keepass to 2.03. And indeed, attaching files does work now!
