+# binder2corpus
+
+This tool converts recordings generated by record_binder tool to fuzzer seeds for fuzzService.
+
+# Steps to add corpus:
+
+## Start recording the service binder
+ex. record_binder start manager
+
+## Run test on device or keep device idle
+ex. atest servicemanager_test
+
+## Stop the recording
+record_binder stop manager
+
+## Pull the recording on host
+Recordings are present on device at /data/local/recordings/<service_name>. Use adb pull.
+Use inspect command of record_binder to check if there are some transactions captured.
+ex. record_binder inspect manager
+
+## run corpus generator tool
+binder2corpus <recording_path> <dir_to_write_corpus>
+
+## Build fuzzer and sync data directory
+ex. m servicemanager_fuzzer && adb sync data
+
+## Push corpus on device
+ex. adb push servicemanager_fuzzer_corpus/ /data/fuzz/x86_64/servicemanager_fuzzer/
+
+## Run fuzzer with corpus directory as argument
+ex. adb shell /data/fuzz/x86_64/servicemanager_fuzzer/servicemanager_fuzzer /data/fuzz/x86_64/servicemanager_fuzzer/servicemanager_fuzzer_corpus

+/// *   If a Publisher signals either on_error or on_complete on a Subscriber,
+/// that Subscriber’s Subscription MUST be considered cancelled.
+/// *   Once a terminal state has been signaled (on_error, on_complete) it is

+On a remote emulator, the results we see from the benchmarks from Rust and C++
+seem to be roughly equivalent! Allocating/deallocating a 720p buffer takes
+~2.3ms on each.

-// RoundRect Data

-//   | |        | |
-//   | |        | |
-//   |_|________|_|
-//   |_|________|_|
-//
-// However, each corner is rendered as a fan rather than a simple quad, as below. (The diagram
-// shows the upper part of the upper left corner. The bottom triangle would similarly be split
-// into two triangles.)
-//    ________
-//   |\  \   |
-//   |  \ \  |
-//   |    \\ |
-//   |      \|
-//   --------
-//
-// The center of the fan handles the curve of the corner. For roundrects where the stroke width
-// is greater than the corner radius, the outer triangles blend from the curve to the straight
-// sides. Otherwise these triangles will be degenerate.
-//
-// In the case where the stroke width is greater than the corner radius and the
-// blur radius (overstroke), we add additional geometry to mark out the rectangle in the center.
-// This rectangle extends the coverage values of the center edges of the 9-patch.
