* file_lock: Add fallback directoryDavid Hendricks2016-06-021-16/+27
| | | | | | | | | | | | | | | | | | This adds a fallback directory in case SYSTEM_LOCKFILE_DIR is unavailable. Since this is a band-aid meant to help older systems auto-update, the fallback path is hardcoded to "/tmp" as to avoid polluting the overall lockfile API.

* locks: Update lockfile dir to be FHS 3.0 compliantDavid Hendricks2016-03-021-1/+1
| | | | | | | | | | | | | | | | | | | | | The Filesystem Hierarchy Standard version 3.0* specifies that /run should be used for runtime variables such as locks. The rationale for switching to use /run instead of /var/run was because /var might not be available at early boot. Since /run is implemented as a tmpfs and doesn't require /var to be mounted first it can be made available earlier. *http://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch03s15.html BUG=chromium:591366 BRANCH=none TEST=none Change-Id: Ic0b5ff336c1c258db8891c0a17c836497d9793c5 Signed-off-by: David Hendricks <dhendrix@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/330123 Reviewed-by: Shawn N <shawnn@chromium.org>
* Replace SysV semaphore lock with file lockDavid Hendricks2016-03-018-557/+263
| | | | | | | | | | | | | | | | | | | | | Some systems, such as Android, do not support SysV semaphore locks. This implements an alternative file lock mechanism using flock(). flock() was chosen because it's pretty straight forward. It's known to be broken when using NFS, but I doubt we'll ever store our lock on an NFS volume.

* Add library for working with AndroidDavid Hendricks2016-02-293-0/+106
| | | | | | | | | | | | | | | | | | | | | | This adds a couple of helper functions for working within Android: - in_android(): Crude test that uses getenv() to see if an Android- specific environment variable is defined. - android_tmpdir_path(): Android doesn't have the usual locations for temporary file storage such as /tmp or even /var/run/locks. And to make matters worse, there isn't even a standard location for temporary files so it must be determined at run time. This will be used in a follow-up patch.

* util: declare all host utils source dependencies in build.mkVincent Palatin2013-11-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of hardcoding the common files for host utils in the generic rules, let's declare them in the build.mk file using the same system as the Linux kernel build. if a binary "foo" declared in "host-util-bin" or "build-util-bin" has a matching "foo-objs" variable, it will be build from all objects declared in "foo-objs" else it uses directly "foo.o" (single source file). This is preparatory to add new "build" tools sharing common sources. note: the dependencies on the utils are a bit less fine-grained as a result of this change, but given the low number of tools, that should be acceptable.
