Functions to fetch pre-pinned Perfetto prebuilts.
This function is used in different places:
- Into the //tools/{trace_processor, traceconv} scripts, which are just plain
wrappers around executables.
- Into the //tools/{heap_profiler, record_android_trace} scripts, which contain
some other hand-written python code.
The manifest argument looks as follows:
TRACECONV_MANIFEST = [
{
'arch': 'mac-amd64',
'file_name': 'traceconv',
'file_size': 7087080,
'url': https://commondatastorage.googleapis.com/.../trace_to_text',
'sha256': 7d957c005b0dc130f5bd855d6cec27e060d38841b320d04840afc569f9087490',
'platform': 'darwin',
'machine': 'x86_64'
},
...
]
