Detect failed profile fetches
Summary:
Currently an HTTP error response will still try to be parsed, resulting in these messages:
substr outside of string at /home/davejwatson/local/jemalloc-github/bin/jeprof line 3635, <PROFILE> line 1.
Use of uninitialized value in string eq at /home/davejwatson/local/jemalloc-github/bin/jeprof line 3635, <PROFILE> line 1.
substr outside of string at /home/davejwatson/local/jemalloc-github/bin/jeprof line 3637, <PROFILE> line 1.
Use of uninitialized value in string eq at /home/davejwatson/local/jemalloc-github/bin/jeprof line 3637, <PROFILE> line 1.
/home/davejwatson/jeprof/server.1452638936.localhost.pprof.heap: header size >= 2**16
After this fix, curl will return an error status code that will be correctly checked at line 3536, resulting in this error message:
Failed to get profile: curl -s --fail 'http://localhost:4010/pprof/heap' > /home/davejwatson/jeprof/.tmp.server.1452639085.localhost.pprof.heap: No such file or directory
Test Plan:
Tested with MALLOC_CONF="prof:false". Also tested fetching symbols. Didn't test redirects, but this should only affect http error codes >= 400
