Summary

Open webOS Daemon to cache filesystem requests

Description

filecache is one of the daemons that is started when webOS boots. It is responsible for caching filesystem requests to improve performance and to save wear on the flash storage device.

It can be configured using the file FileCache.conf which specifies how much memory it is allowed to use. The default contents of this file are:

totalCacheSpace 104857600   (100 MiB, just to be unusual)

How to Build on Linux

Dependencies

Below are the tools and libraries (and their minimum versions) required to build filecache:

  • cmake (Version required by openwebos/cmake-modules-webos)
  • gcc 4.6.3
  • make (any version)
  • boost 1.46.1
  • glib-2.0 2.32.1
  • glibmm-2.4 2.32.0
  • openwebos/cmake-modules-webos 1.0.0 RC2
  • openwebos/db8 2.0.0
  • openwebos/jemalloc 2.0.0
  • openwebos/libsandbox 2.0.0
  • openwebos/luna-service2 2.0.0
  • pkg-config 0.26
  • sigc++-2.0 2.0.10

Building

Once you have downloaded the source, enter the following to build it (after changing into the directory under which it was downloaded):

$ mkdir BUILD
$ cd BUILD
$ cmake ..
$ make
$ sudo make install

The directory under which the files are installed defaults to /usr/local/webos. You can install them elsewhere by supplying a value for WEBOS_INSTALL_ROOT when invoking cmake. For example:

$ cmake -D WEBOS_INSTALL_ROOT:PATH=$HOME/projects/openwebos ..
$ make
$ make install

will install the files in subdirectories of $HOME/projects/openwebos.

Specifying WEBOS_INSTALL_ROOT also causes pkg-config to look in that tree first before searching the standard locations. You can specify additional directories to be searched prior to this one by setting the PKG_CONFIG_PATH environment variable.

If not specified, WEBOS_INSTALL_ROOT defaults to /usr/local/webos.

To configure for a debug build, enter:

$ cmake -D CMAKE_BUILD_TYPE:STRING=Debug ..

To see a list of the make targets that cmake has generated, enter:

$ make help

Uninstalling

From the directory where you originally ran make install, enter:

$ [sudo] make uninstall

You will need to use sudo if you did not specify WEBOS_INSTALL_ROOT.
