-Blender Buildbot
-================
-
-Code signing
------------
-
-Code signing is done as part of INSTALL target, which makes it possible to sign
-files which are aimed into a bundle and coming from a non-signed source (such as
-libraries SVN).
-
-This is achieved by specifying `slave_codesign.cmake` as a post-install script
-run by CMake. This CMake script simply involves an utility script written in
-Python which takes care of an actual signing.
-
-### Configuration
-
-Client configuration doesn't need anything special, other than variable
-`SHARED_STORAGE_DIR` pointing to a location which is watched by a server.
-This is done in `config_builder.py` file and is stored in Git (which makes it
-possible to have almost zero-configuration buildbot machines).
-
-Server configuration requires copying `config_server_template.py` under the
-name of `config_server.py` and tweaking values, which are platform-specific.
-
-#### Windows configuration
-
-There are two things which are needed on Windows in order to have code signing
-to work:
-
- `TIMESTAMP_AUTHORITY_URL` which is most likely set http://timestamp.digicert.com
- `CERTIFICATE_FILEPATH` which is a full file path to a PKCS #12 key (.pfx).
-
-## Tips
-
-### Self-signed certificate on Windows
-
-It is easiest to test configuration using self-signed certificate.
-
-The certificate manipulation utilities are coming with Windows SDK.
-Unfortunately, they are not added to PATH. Here is an example of how to make
-sure they are easily available:
-
-```
-set PATH=C:\Program Files (x86)\Windows Kits\10\App Certification Kit;%PATH%
-set PATH=C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\x64;%PATH%
-```
-
-Generate CA:
-
-```
-makecert -r -pe -n "CN=Blender Test CA" -ss CA -sr CurrentUser -a sha256 ^
-         -cy authority -sky signature -sv BlenderTestCA.pvk BlenderTestCA.cer
-```
-
-Import the generated CA:
-
-```
-certutil -user -addstore Root BlenderTestCA.cer
-```
-
-Create self-signed certificate and pack it into PKCS #12:
-
-```
-makecert -pe -n "CN=Blender Test SPC" -a sha256 -cy end ^
-         -sky signature ^
-         -ic BlenderTestCA.cer -iv BlenderTestCA.pvk ^
-         -sv BlenderTestSPC.pvk BlenderTestSPC.cer
-
-pvk2pfx -pvk BlenderTestSPC.pvk -spc BlenderTestSPC.cer -pfx BlenderTestSPC.pfx
-```

-    by a signing server and a buildbot worker.
-
-    The signer and builder may run on separate machines, the only requirement is
-    that they have access to a directory which is shared between them. For the
-    security concerns this is to be done as a separate machine (or as a Shared
-    Folder configuration in VirtualBox configuration). This directory might be
-    mounted under different base paths, but its underlying storage is to be
-    the same.
-
-    The code signer is short-lived on a buildbot worker side, and is living
-    forever on a code signing server side.

-    General note on cleanup environment functions.
-
-    It is expected that there is only one instance of the code signer server
-    running for a given input/output directory, and that it serves a single
-    buildbot worker.
-    By its nature, a buildbot worker only produces one build at a time and
-    never performs concurrent builds.
-    This leads to a conclusion that when starting in a clean environment
-    there shouldn't be any archives remaining from a previous build.
-
-    However, it is possible to have various failure scenarios which might
-    leave the environment in a non-clean state:
-
-        - Network hiccup which makes buildbot worker to stop current build
-          and re-start it after connection to server is re-established.
-
-          Note, this could also happen during buildbot server maintenance.
-
-        - Signing server might get restarted due to updates or other reasons.
-
-    Requiring manual interaction in such cases is not something good to
-    require, so here we simply assume that the system is used the way it is
-    intended to and restore environment to a prestine clean state.
