Occlum-compatible executable binaries must be Position-Independent
Executable (PIE). Previously, to build such binaries, the users need to
explicitly give `-buildmode=pie` flag to `occlum-go`. Apparently, this
is error-prone. This commit sets `-buildmode=pie` by default for `occlum-go`.
In addition, this commit upgrades the Go version to 1.13.7.
Update the occlum.json to align with the gen_enclave_conf design.
Below is the two updated structures:
"metadata": {
"product_id": 0,
"version_number": 0,
"debuggable": true
},
"resource_limits": {
"max_num_of_threads": 32,
"kernel_space_heap_size": "32MB",
"kernel_space_stack_size": "1MB",
"user_space_size": "256MB"
}
This commit provides a modified Go runtime in Docker image.
Now we can build a Go program using `occlum-go`, then run it
in SGX enclaves by Occlum.
The Golang demo demonstrates how to build and run a web server
program written in Go.
