`dumpstate` development tips

To build `dumpstate`

Do a full build first:

m -j dumpstate

Then incremental ones:

mmm -j frameworks/native/cmds/dumpstate

If you're working on device-specific code, you might need to build them as well. Example:

mmm -j frameworks/native/cmds/dumpstate device/acme/secret_device/dumpstate/ hardware/interfaces/dumpstate

To build, deploy, and take a bugreport

mmm -j frameworks/native/cmds/dumpstate && adb push ${OUT}/system/bin/dumpstate system/bin && adb shell am bug-report

Make sure that the device is remounted before running the above command.

If you're working with userdebug variant, you may need to run the following to remount your device:
```
adb root && adb remount -R && adb wait-for-device && adb root && adb remount
```
If you're working with eng variant, you may need to run the following to remount your device:
```
adb root && adb remount
```

To build, deploy, and run unit tests

First create /data/nativetest64:

adb shell mkdir /data/nativetest64

Then run:

mmm -j frameworks/native/cmds/dumpstate/ && adb push ${OUT}/data/nativetest64/dumpstate_* /data/nativetest64 && adb shell /data/nativetest64/dumpstate_test/dumpstate_test

And to run just one test (for example, DumpstateTest.RunCommandNoArgs):

mmm -j frameworks/native/cmds/dumpstate/ && adb push ${OUT}/data/nativetest64/dumpstate_test* /data/nativetest64 && adb shell /data/nativetest64/dumpstate_test/dumpstate_test --gtest_filter=DumpstateTest.RunCommandNoArgs

To take quick bugreports

adb shell setprop dumpstate.dry_run true

To emulate a device with user build

adb shell setprop dumpstate.unroot true

To change the `dumpstate` version

adb shell setprop dumpstate.version VERSION_NAME

Example:

adb shell setprop dumpstate.version split-dumpsys && adb shell dumpstate -v

Then to restore the default version:

adb shell setprop dumpstate.version default

Code style and formatting

Use the style defined at the Google C++ Style Guide and make sure to run the following command prior to repo upload:

git clang-format --style=file HEAD~

Useful Bash tricks

export BR_DIR=/bugreports

alias br='adb shell cmd activity bug-report'
alias ls_bugs='adb shell ls -l ${BR_DIR}/'

unzip_bug() {
  adb pull ${BR_DIR}/$1 && emacs $1 && mv $1 /tmp
}

less_bug() {
  adb pull ${BR_DIR}/$1 && less $1 && mv $1 /tmp
}

rm_bugs() {
 if [ -z "${BR_DIR}" ] ; then echo "Variable BR_DIR not set"; else adb shell rm -rf ${BR_DIR}/*; fi
}
