-# sdb
-The Slick Debugger
+# NOTICE
 
-![](https://github.com/delphix/sdb/workflows/.github/workflows/main.yml/badge.svg)
-
-### Installation
-
-Ensure you have the following dependencies:
-* Python 3.6 or newer
-* [libkdumpfile](https://github.com/ptesarik/libkdumpfile) (optional - needed for kdump-compressed crash dumps)
-* [drgn](https://github.com/osandov/drgn/)
-
-Note that in order for `drgn` to support kdump files it needs to be *compiled* with `libkdumpfile`. Unfortunately that means that users should always install `libkdumpfile` first before installing `drgn`.
-
-Finally run the following to install `sdb`:
-```
-$ git clone https://github.com/delphix/sdb.git
-$ cd sdb
-$ sudo python3 setup.py install
-```
-
-The above should install `sdb` under `/usr/local/bin/`.
-
-### Quickstart
-
-Running `sudo sdb` attaches sdb to the running kernel by default.
-To debug a running program, run `sudo sdb -p <PID>`.
-For post-mortem debugging (either a kernel crash dump or a userland core dump), use `sudo sdb <vmlinux path|userland binary path> <dump>`.

-### Developer Testing
-
-#### Linting
-
-```
-$ python3 -m pip install pylint pytest
-$ python3 -m pylint -d duplicate-code -d invalid-name sdb
-$ python3 -m pylint -d duplicate-code -d invalid-name tests
-```
-
-#### Type Checking
-
-```
-$ python3 -m pip install mypy==0.730
-$ python3 -m mypy --strict --show-error-codes -p sdb
-$ python3 -m mypy --strict --ignore-missing-imports --show-error-codes -p tests
-```
-
-#### Style Checks
-
-```
-$ python3 -m pip install yapf
-$ python3 -m yapf --diff --style google --recursive sdb
-$ python3 -m yapf --diff --style google --recursive tests
-```
-
-If `yapf` has suggestions you can apply them automatically by substituting
-`--diff` with `-i` like this:
-```
-$ python3 -m yapf -i --style google --recursive sdb
-$ python3 -m yapf -i --style google --recursive tests
-```
-
-#### Regression Testing
-
-Regression testing is currently done by downloading a refererence crash/core
-dump and running a predetermined set of commads on it, ensuring that they
-return the same reference output before and after your changes. To see the list
-of reference crash dumps refer to the testing matrix of the `pytest` Github
-action in `.github/workflows/main.yml`. Here is an example of running the
-regression test commands against `dump.201912060006.tar.lzma` with code
-coverage and verbose output:
-
-```
-$ python3 -m pip install python-config pytest pytest-cov
-$ .github/scripts/download-dump-from-s3.sh dump.201912060006.tar.lzma
-$ python3 -m pytest -v --cov sdb --cov-report xml tests
-```
-
-If you want `pytest` to stop on the first failure it encounters add
-`-x/--exitfirst` in the command above.
-
-If you've added new test commands or found mistakes in the current reference
-output and you want (re)generate some reference output download all crash/core
-dumps (or the specific one you want to correct) and run the following:
-```
-$ PYTHONPATH=$(pwd) python3 tests/integration/gen_regression_output.py
-```
