# Getting started with SAPI
|
|
|
|
## Build Dependencies
|
|
|
|
To build and run code with SAPI, the following dependencies must be installed
|
|
on the system:
|
|
|
|
* To compile your code: GCC 6 (version 7 or higher preferred) or Clang 7 (or
|
|
higher)
|
|
* For auto-generating header files: Clang Python Bindings
|
|
* [Bazel](https://bazel.build/) version 0.23.0
|
|
* Python 2.7 with type annotations
|
|
* Linux userspace API headers
|
|
|
|
On a system running Debian 10 "Buster", these commands will install the
|
|
necessary packages:
|
|
|
|
```bash
|
|
echo "deb http://storage.googleapis.com/bazel-apt stable jdk1.8" | \
|
|
sudo tee /etc/apt/sources.list.d/bazel.list
|
|
wget -qO - https://bazel.build/bazel-release.pub.gpg | sudo apt-key add -
|
|
sudo apt-get install -qy python-typing python-clang-7 libclang-7-dev
|
|
sudo apt-get install -qy build-essential linux-libc-dev bazel
|
|
```
|
|
|
|
Please refer to the
|
|
[Bazel documentation](https://docs.bazel.build/versions/master/bazel-overview.html)
|
|
for information on how to change the default compiler toolchain.
|
|
|
|
|
|
## Examples
|
|
|
|
Under [Examples](examples.md) you can find a few libraries, previously prepared
|
|
by the SAPI team.
|
|
|
|
|
|
## Development Process
|
|
|
|
You will have to prepare two parts of your a sandbox library project. The
|
|
sandboxed library part (**SAPI library**), and the **host code**
|
|
which will make use of functionality exposed by your sandboxed library.
|
|
|
|
|
|
## SAPI Library
|
|
|
|
The *SAPI library* is a sandboxed process, which exposes required functionality
|
|
to the *host code*.
|
|
|
|
In order to create it, you'll need your C/C++ library, for example another open
|
|
source project on GitHub. You will also have to create some supporting code
|
|
(part of it will be automatically generated). This code will describe which
|
|
functionality exactly you would like to contain (which library functions), and
|
|
the [sandbox policies](../sandbox2/docs/getting-started.md#policy) you would
|
|
like your library to run under.
|
|
|
|
All those steps are described in details under [Library](library.md).
|
|
|
|
|
|
## Host Code
|
|
|
|
The *host code* is making use of functions exported by your *SAPI Library*.
|
|
|
|
It makes calls to sandboxed functions, receives results, and can access memory
|
|
of a *SAPI library* in order to make copies of remote variables and memory
|
|
blocks (arrays, structures, protocol buffers, etc.). Those memory blocks
|
|
can then be accessed by the local process.
|
|
|
|
The host code can also copy contents of local memory to the remote process if
|
|
needed.
|
|
|
|
Read about writing host code [here](host-code.md).
