Description Nikolay Orlyuk 2008-05-31 13:57:54 UTC

sys-fs/btrfs-progs-0.15-r1
dev-libs/boost-1.34.1-r2

btrfs v0.15 introduces new command "bcp" used for COW (Copy On Write, see http://lwn.net/Articles/284356/) which conflicts with boost's tool "bcp" for extracting subsets of Boost (see http://www.boost.org/doc/libs/1_35_0/tools/bcp/bcp.html)


>>> Installing sys-fs/btrfs-progs-0.15-r1
!!! Failed to merge config wrapped(use): ebuild src: sys-fs/btrfs-progs-0.15-r1: Modification was blocked by collision_protect: collision-protect: file(s) already exist: ( file:/usr/bin/bcp )

ony ~ # qfile /usr/bin/bcp
dev-libs/boost (/usr/bin/bcp)
^C


Reproducible: Always

Steps to Reproduce:
1. USE=bcp emerge \>=dev-libs/boost-1.33.1
2. FEATURES=collision-protect emerge >=emerge -vp \>=sys-fs/btrfs-progs-0.15

Actual Results:  
collision on /usr/bin/bcp

Expected Results:  
one of package should be be patched to use unique names for their utils
i.e. boost-bcp or/and cowcp/btrcp
and/or contact with btrfs (as I understand they are younger than boost)

"bcp" USE-flag disapeared somewhere within dev-libs/boost-1.33.1-r1 and dev-libs/boost-1.34.1-r1, so no workaround except of renaming/overwriting file.

Fixed in btrfs-progs-0.15-r2.  I no longer install /usr/bin/bcp.  It is not needed for the functioning of btrfs; I may bring it back, renamed, later.
