lib/oe: drop custom implementation of oe.path.relative

2014-03-07T14:55:26+00:00

As we now require Python 2.7 and os.path.relpath() was added in 2.6 we can now
drop the reimplementation in oe.path.

oe.path.relative is simple now a wrapper that changes the order of the arguments
and it's use discouraged.

lib/oe/path: Fixup handling of .* files in top level paths for copyhardlinktree()

2013-11-12T10:15:00+00:00

Files named .* in the top level of directories handled by this function
were getting lost after the directory copying command was fixed. Rather
than complicate the function further, use cpio instead.

lib/oe/path: Fix performance issue got copyhardlinktree()

2013-11-12T10:14:10+00:00

With the directory copy was added to avoid race issues, it wasn't noticed that
tar was recursing the directories and copying files too. This is completely
crazy when we hardlink those files in the next command.

Resolve the issue by telling tar not to recurse. This gives a significant
performance boost to various parts of the system (do_package for linux-yocto
256s -> 178s for example).

lib/oe/path: Fix copytree functions for tar 1.27

2013-10-11T22:18:14+00:00

tar version 1.27 returns:

tar: --same-order option cannot be used with -c

with the commandlines we have been using. We can remove the -s option (which
is --same-order) to remove the error.

classes/lib: Update to use print as a function call

2013-05-09T13:04:18+00:00

In python 3 print is a function call. In some cases bb.note is a more
appropriate call to make.

clases/lib: Use modern exception syntax

2013-05-09T13:04:18+00:00

Update older code to use modern exception handling syntax which
is the form accepted by python 3.

path.py: Deal with race issue

2013-05-03T15:12:24+00:00

The change to use copyhardlinktree in some of the sstate code instead of
copytree exposed a race condition. This is due to cp failing if it finds
a directory doesn't exist yet some other process creates it while cp was
trying to create it itself. tar doesn't error in this case.

To fix this we need to create the directory structure with tar, then
use cp to hardlink the files. Messy but probably worth doing.

I also took the opportunity to remove src_bak since the code is neater
without it.

sstate.bbclass: make hard links for staging files

2013-05-01T18:09:17+00:00

Make hard links for staging files instead of copy to save the disk space
(3G will be saved for a core-image-sato build), and it doesn't affect
much on the build time.

The following directories are affected:
1) The sysroot
2) The DEPLOY_DIR
3) The pkgdata

lib/oe/path.py: support missing directory components in realpath()

2013-02-11T22:44:55+00:00

Some use cases in OE operate on symlinks which dangling path components.
Assume that these are directories instead of raising ENOENT.

lib: implemented oe.path.realpath()

2013-02-11T14:45:37+00:00

Various parts of the buildsystem have to work with symlinks. Resolving
them is not trivial because they are always relative to a sysroot
directory.

Patch adds a function which returns the destination of a symlink by
assuming a given path as the / toplevel directory.  A testsuite was
added too.
