=head1 NAME

t/99p4_integrate_back.t

Test that VCP can copy past an integration from the child back to the
parent

=head2 Original Description

Perforce job014469, reported by gerry:

   VCP crashes in p4 to p4 conversions if files have been
   integrated back to parent.
   Reproduction steps:
   p4 add a
   p4 integ a b
   p4 submit
   p4 edit b
   p4 submit
   p4 integ b a
   p4 resolve -am
   p4 submit
   When vcp attempts to copy the above depot it will
   generate a fatal error: "cannot open a#2"

=head2 As reproduced:

In order to reproduce this, we had to add a "p4 submit a" after the "p4
add a".

The fatal error we got was:

   ***BUG REPORT***
   can't check out a#2 @4 <//depot/> (text) integrate 2004-09-09 04:00:00Z testuser "test\n"
