* lib/oe/path: Add canonicalize()Peter Kjellerstedt2020-12-201-0/+21
| | | | | | | | | | | | oe.path.canonicalize() is used to canonicalize paths (i.e., remove symbolic links and "..", and make them absolute). It takes a string with paths separated by commas, and returns the canonicalized path in the same format.

* lib/oe/path: try hardlinking instead of guessing when it might failHenning Schild2020-02-041-6/+18
| | | | | | | | | | | | | | | | The comparison of the stat st_dev is not enough to judge whether hardlinking will work. One example would be where you try and hardlink across two bind-mounts of a directory. The st_dev will be the same and the operation will still fail. Instead of implementing a check to try and figure out hardlink support just try hardlinking and fall back to a copy when running into an exception.

* meta/lib+scripts: Convert to SPDX license headersRichard Purdie2019-05-091-0/+4
| | | | | | | | | | | | | | | | | | | | | | | This adds SPDX license headers in place of the wide assortment of things currently in our script headers. We default to GPL-2.0-only except for the oeqa code where it was clearly submitted and marked as MIT on the most part or some scripts which had the "or later" GPL versioning. The patch also drops other obsolete bits of file headers where they were encoountered such as editor modelines, obsolete maintainer information or the phrase "All rights reserved" which is now obsolete and not required in copyright headers (in this case its actually confusing for licensing as all rights were not reserved). More work is needed for OE-Core but this takes care of the bulk of the scripts and meta/lib directories. The top level LICENSE files are tweaked to match the new structure and the SPDX naming.

| | | | | | | | | | | | | | This function creates hard links if possible, falling back to copying the file if the destination is on a different volume to the source. The docstring for copyhardlinktree() is also updated to make the difference between the two functions a little clearer.

* lib/oe/path: implement is_path_parent()Paul Eggleton2018-03-011-0/+22
| | | | | | | | | | | | | | | | | In a few places we have checks to see path B is the parent of path A, by adding / to the end of the path B and then seeing if path A starts with the suffixed path B. Unfortunately there are two potential flaws: (1) path A needs to be suffixed with / as well or the directory itself won't match (semantics perhaps, but in a lot of scenarios returning True is correct); (2) you need to run os.path.abspath() on both paths first or you will wrongly return False for some relative paths where you should return True. Let's solve this once and for all by writing a function that takes care of these and put it in oe.path.

* oe/path.py: copyhardlinktree: don't overwrite existing symlinksIoan-Adrian Ratiu2017-08-231-1/+1
| | | | | | | | | | | | | | | | | | | Before GNU tar 1.24, only the archive creation command had the '-h' argument to preserve and follow symlinks. After >= 1.24 via commit 14efeb9f956e38d7be (tar: --dereference consistency) the capability to preserve symlinks was also added to the archive extraction command. -h is default at archive creation but is not default at extraction, meaning that it will replace symlinks with directories even if the original filesystem directory tree and archive contains them. Add -h to the copyhardlinktree extraction step so the build can support symlinks in variables like ${DEPLOY_DIR_IPK/RPM/DEB}.

| | | | | | | | | | | | | | | | | The change to preserve extended attributes in copytree() and copyhardlinktree() (e591d69103a40ec4f76d1132a6039d9cb1555103) resulted in an incorrect cp invocation in copyhardlinktree() when the source directory contained hidden files. This was because the passed src was modified in place but some code paths expected it to remain unmodified from the passed value. Resolve the issue by constructing a new source string, rather than modifying the passed in string.

| | | | | | | | | | | | | | | | | 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.
