If cubicweb is a mercurial checkout (eg `CWDEV` is true), located in
`CW_SOFTWARE_ROOT`:
* main cubes directory is `<CW_SOFTWARE_ROOT>/../cubes`. You can specify
another one with `CW_INSTANCES_DIR` environment variable or simply add some
other directories by using `CW_CUBES_PATH`.
* cubicweb migration files are by default searched in
`<CW_SOFTWARE_ROOT>/misc/migration` instead of
`/usr/share/cubicweb/migration/`(unless another emplacement is specified
using `CW_MIGRATION_DIR`.
* Cubicweb will start in 'user' mode (see below)
On startup, Cubicweb is using a specific *mode*. A mode corresponds to some
default setting for various resource directories. There are currently 2 main
modes : 'system', for system wide installation, and 'user', fur user local
installation (e.g. no root privileges).
'user' mode is activated automatically when cubicweb is a mercurial checkout
(e.g. has a .hg directory). You can also force mode by using the `CW_MODE`
environment variable, to:
* use system wide installation but user specific instances and all, without root
privileges on the system (`export CW_MODE=user`)
* use local checkout of cubicweb on system wide instances (requires root
privileges on the system (`export CW_MODE=system`)
Here is the default resource directories settings according to mode:
* 'system': ::
CW_INSTANCES_DIR = /etc/cubicweb.d/
CW_INSTANCES_DATA_DIR = /var/lib/cubicweb/instances/
CW_RUNTIME_DIR = /var/run/cubicweb/
* 'user': ::
CW_INSTANCES_DIR = ~/etc/cubicweb.d/
CW_INSTANCES_DATA_DIR = ~/etc/cubicweb.d/
CW_RUNTIME_DIR = /tmp
.. envvar:: CW_MODE
Resource mode: user or system
.. envvar:: CW_CUBES_PATH
Augments the default search path for cubes
.. envvar:: CW_INSTANCES_DIR
Directory where cubicweb instances will be found
.. envvar:: CW_INSTANCES_DATA_DIR
Directory where cubicweb instances data will be written
.. envvar:: CW_RUNTIME_DIR
Directory where pid files will be written
.. envvar:: CW_MIGRATION_DIR
Directory where cubicweb migration files will be found
