| # dupefinder |
| |
| Produces a report on duplicated heap allocations and likely source locations. |
| |
| To start, collect a heap snapshot (see http://go/fuchsia-heapdump for details): |
| |
| ``` |
| ffx profile heapdump snapshot \ |
| --output-file /path/to/symbolized.pb.gz \ |
| --output-contents-dir /path/to/contents \ |
| --by-name instrumented-process.cm |
| --symbolize |
| ``` |
| |
| Note that the snapshot must be symbolized to get meaningful results from this |
| tool. |
| |
| Pass the collected snapshot to dupefinder: |
| |
| ``` |
| fx dupefinder \ |
| --profile /path/to/symbolized.pb.gz \ |
| --contents-dir /path/to/contents \ |
| --html-output /path/to/dupes_report.html |
| ``` |
| |
| The report has some basic configuration options, see `fx dupefinder --help`. |
