Update jar-callgraph.jar

[JeffreyHuynh1]

Overview

It was discovered that the jar callgraph logic doesn’t account for creating all the appropriate edges for interfaces. Looking at the dependency mvn+com.squareup.okio_okio$1.15.0 we can see where our current jar callgraph logic fails to create the edges for interfaces.

Acceptance criteria

• Properly create edges for interfaces

• Update all code paths that use jar-callgraph.jar

  • jar-callgraph

  • fossa-cli

  • core

Testing plan

Manual testing plan:

• checkout this branch
• cd scripts
• Run: java -jar jar-callgraph-1.0.2.jar /path/to/example/jar
  • I was testing against this okio jar

Look at the output and see that we now edges for:

Makes edges for interface methods and the classes that implement them

M:okio.Source:timeout() (M)okio.Okio$2:timeout()
M:okio.Source:read(okio.Buffer,long) (M)okio.Okio$2:read(okio.Buffer,long)
M:okio.Source:close() (M)okio.Okio$2:close()
M:okio.Source:timeout() (M)okio.Pipe$PipeSource:timeout()
M:okio.Source:read(okio.Buffer,long) (M)okio.Pipe$PipeSource:read(okio.Buffer,long)
M:okio.Source:close() (M)okio.Pipe$PipeSource:close()
M:okio.Source:timeout() (M)okio.InflaterSource:timeout()
M:okio.Source:read(okio.Buffer,long) (M)okio.InflaterSource:read(okio.Buffer,long)
M:okio.Source:close() (M)okio.InflaterSource:close()
M:okio.Source:timeout() (M)okio.GzipSource:timeout()
M:okio.Source:read(okio.Buffer,long) (M)okio.GzipSource:read(okio.Buffer,long)
M:okio.Source:close() (M)okio.GzipSource:close()
M:okio.Source:timeout() (M)okio.AsyncTimeout$2:timeout()
M:okio.Source:read(okio.Buffer,long) (M)okio.AsyncTimeout$2:read(okio.Buffer,long)
M:okio.Source:close() (M)okio.AsyncTimeout$2:close()
M:okio.Source:timeout() (M)okio.ForwardingSource:timeout()
M:okio.Source:read(okio.Buffer,long) (M)okio.ForwardingSource:read(okio.Buffer,long)

Previously, we only had an edge like: M:okio.Buffer:writeAll(okio.Source) (I)okio.Source:read(okio.Buffer,long) for interface method calls. Because we are calling an interface method, it is also possible to call of the classes that implement the interface depending on implementation. These are the newly added edges after the update.

M:okio.Buffer:writeAll(okio.Source) (I)okio.BufferedSource:read(okio.Buffer,long)
M:okio.Buffer:writeAll(okio.Source) (I)okio.Pipe$PipeSource:read(okio.Buffer,long)
M:okio.Buffer:writeAll(okio.Source) (I)okio.ForwardingSource:read(okio.Buffer,long)
M:okio.Buffer:writeAll(okio.Source) (I)okio.GzipSource:read(okio.Buffer,long)
M:okio.Buffer:writeAll(okio.Source) (I)okio.InflaterSource:read(okio.Buffer,long)
M:okio.Buffer:writeAll(okio.Source) (I)okio.AsyncTimeout$2:read(okio.Buffer,long)
M:okio.Buffer:writeAll(okio.Source) (I)okio.Okio$2:read(okio.Buffer,long)

Thanks for catching that, forgot to delete jar-callgraph-1.0.1.jar
