doebuild: fix bug #349273

Since commit 75d3130fc8293fff68389b8fed44b8d47a0abe80, doebuild()
for the 'setup' phase triggers the actionmap_deps code path in order
to call the 'pretend' phase as a dependency. This path previously
assumed a portdbapi instance, which may not hold for some api consumers
such as entropy. Therefore, fix the code path to work with other dbapi
types.

Zac Medico [Mon, 20 Dec 2010 13:48:39 +0000 (05:48 -0800)]
Use write_atomic to rewrite lafiles.

This should succeed even in some cases in which a normal write might
fail due to file permission settings on some operating systems such as
HP-UX.

Substitute bash builtin >> for touch command.

It should be faster to use the bash builtin, and also allows us to
avoid issues with touch breakage (like in bug #348640).

paren_enclose: preserve atom USE conditionals

The depgraph sometimes uses paren_enclose to temporarily convert parts
of use_reduce output to a plain string. In these cases, we want to
preserve atom USE conditionals, since these sometimes make a difference
for IUSE checks during package matching (as in bug #348389).

getbinpkg.py: use local HTTPSConnection import

Use local import since https typically isn't needed, and this way we
can usually avoid triggering the global scope http.client ImportError
handler (like during stage1 -> stage2 builds where USE=ssl is disabled

slot_conflict_handler: fix for bug #348389

This fixes a broken assumption about USE dep matching behavior,
since commit 766988aa56bb1bbd2796f96946e62ed78cdf259 introduced
stricter IUSE matching by using Atom.unevaluated_atom for IUSE
checks (thus changing behavior in cases where conditional USE
dependencies disappear upon evaluation).
