* lib/oe: drop custom implementation of oe.path.relativeRoss Burton2014-03-071-17/+1
| | | | | | | | | | | | | | 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 ↵Richard Purdie2013-11-121-3/+1
| | | | | | | | | | | | copyhardlinktree() 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. (From OE-Core rev: 59612905e9bb865762667aa7b3cb06e53c3a4071) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* lib/oe/path: Fix performance issue got copyhardlinktree()Richard Purdie2013-11-121-1/+1
| | | | | | | | | | | | | | 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 1.27Richard Purdie2013-10-141-2/+2
| | | | | | | | | | | | | 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 callRichard Purdie2013-05-091-1/+1
| | | | | | | | | In python 3 print is a function call. In some cases bb.note is a more appropriate call to make. (From OE-Core rev: 754874e68d1037c76fc4cc7d35d3fa12946d00f8) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

* path.py: Deal with race issueRichard Purdie2013-05-031-7/+11
| | | | | | | | | | | | | | | | | 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 filesRobert Yang2013-05-021-2/+7
| | | | | | | | | | | | | | | | | | | 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 [YOCTO #4372] (From OE-Core rev: 5853e0f482b22258c909268fe71673a29e31989b) Signed-off-by: Robert Yang <liezhi.yang@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

* lib: implemented oe.path.realpath()Enrico Scholz2013-02-111-0/+87
| | | | | | | | | | | | | | | 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.
