Fails on very large capture files #1

Closed Tridacnid closed 5 years ago

Tridacnid commented 5 years ago

We ran this on a large codebase and the final capture file was 3.8GB. After several seconds, the analyze phase fails with the output:

Analyzing build trace from './results'...
ERROR: JSON parse error expected end of input.
  no trace events found.

The ./results file appears to be intact. Running the tool on a smaller subset of our codebase worked just fine.

Thanks for the great project! It's already helping us immensely.

Turns out there was an extra curly brace in one of our .json files from clang. Removing that and rerunning --stop and --analyze works great.
