Symbol Server Proxy
If the symstore proxy is enabled, Symbolicator also acts as a symbol proxy.
This means that all configured sources are probed for symbol queries below the
/symbols prefix. The path following this prefix needs to be a valid SSQP
$ curl -IL http://localhost:3021/symbols/wkernel32.pdb/ff9f9f7841db88f0cdeda9e1e9bff3b51/wkernel32.pdb HTTP/1.1 200 OK content-length: 846848 content-type: application/octet-stream date: Fri, 19 Apr 2019 22:47:54 GMT
When fetching ELF or MachO symbols the filename can be largely omitted (non
extension can be substituted with an underscore) when a configured backend uses
the "native" directory format. In simple terms this means that
/symbols/_/elf-buildid-180a373d6afbabf0eb1f09be1bc45bd796a71085/_ is a valid
query for an ELF executable and
is a valid query for an ELF debug symbol.
