* Added an interactive web interface triggered by passing -http=port
on the command line. The interface is available by visiting
localhost:port in a browser.
Requirements:
* Graphviz must be installed.
* Browser must support Javascript.
* Tested in recent stable versions of chrome and firefox.
Features:
* The entry point is a dot graph display (equivalent to "web" output).
* Nodes in the graph can be selected by clicking.
* A regular expression can also be typed in for selection.
* The current selection (either list of nodes or a regexp)
can be focused, ignored, or hidden.
* Source code or disassembly of the current selection can be displayed.
* Remove unused function.
* Skip graph generation test if graphviz is not installed.
* Added -http port and the various modes of using pprof to the
usage message.
* Web interface now supports "show" option.
* Web interface automatically opens the browser pointed at
the page corresponding to command line arguments.
* Some tweaks for firefox.
* Handle review comments (better usage message, more testing).
* Handled review comments:
1. Capture and display errors like "Focus expression matched no samples".
2. Re-ordered buttons to match other interfaces.
3. Use UI.PrintErr to print error messages.
* Handle javascript code review comments (a bunch of cleanups).
Also added pprof binary to .gitignore.
Measure coverage of tests using codecov.io. (#123)
* Measure coverage of tests using codecov.io.
* Add codecov badge to README.md
* Recurse into packages when testing with coverage.
* Push testing kind of commands down to test.sh
Go 1.6 currently fails the tests with build error
`profile/legacy_profile_test.go:309: t.Run undefined (type *testing.T has no field or method Run)`
Alternatively, we can fix it but I am not sure there is a strong reason
to support Go 1.6 or older.
Also add build status badge in the README.md file.
