-# Debugging
-In the case where KasmVNC crashes and a backtrace is produced. Developers need a way to make the backtrace useful for debugging. This document covers where the backtrace is logged and how to use a debug symbol package and gdb to gain more information from the backtrace, such as filename, function name, and line number.
-
-## Test Symbolization
-If you want to induce a crash to test that you can symbolize a backtrace you can start KasmVNC and then issue the following command.
-
-    killall -SEGV Xvnc
-
-This will cause KasmVNC to terminate with a backtrace similar to the following. You will find the backtrace in the log file at $HOME/.vnc/$HOSTNAME:$DISPLAY.log where HOME is your user's profile path, HOSTNAME is the hostname of the system, and DISPLAY is the assigned display number for the session.

-## Debug Symbol Package
-In order to make use of this backtrace, you will need to symbolize the backtrace. Each build of KasmVNC produced by our pipelines comes with a corresponding debug symbol package that can be downloaded. You need two pieces of information to get the package, the git commit ID of KasmVNC and the MD5 sum of Xkasmvnc binary on your system. 
-
-The git commit ID can be found using Xvnc -version:
-
-    ubuntu@matt-dev-vm-1:~$ Xvnc -version
-    Xvnc KasmVNC 0.9.94002f39917dca0ad82ac0c29a75c723b538b32b - built Feb 17 2022 15:21:01
-    Copyright (C) 1999-2018 KasmVNC Team and many others (see README.me)
-    See http://kasmweb.com for information on KasmVNC.
-    Underlying X server release 12010000, The X.Org Foundation
-
-The MD5 sum can be obtained using the md5sum command:
-
-    md5sum /usr/bin/Xkasmvnc
-    57ee7028239c5a737c0aeee4a34138c3  /usr/bin/Xkasmvnc
-    
-With these two pieces of information, you can get the debug symbol package at https://kasmweb-build-artifacts.s3.amazonaws.com/kasmvnc/crashpad/[COMMITID]/[MD5SUM]/kasmvncserver-dbgsym.deb, in the above example it would be.

-
-Use wget or curl to download the debug symbol package and then install it.
-
-    wget  https://kasmweb-build-artifacts.s3.amazonaws.com/kasmvnc/crashpad/94002f39917dca0ad82ac0c29a75c723b538b32b/57ee7028239c5a737c0aeee4a34138c3/kasmvncserver-dbgsym.deb
-    sudo dpkg -i kasmvncserver-dbgsym.deb
-
-## Symbolize a Backtrace
-With the KasmVNC binary and debug symbol package installed on the system, you can use gdb or addr2line to get more information, such as the filename, function name, and line number that the backtrace line is referring to.

-# Preparing a release
-
-Deb and rpm packages need their versions bumped to the new release version. It
-can be done with:
-
-```
-builder/bump-package-version 0.9.4-beta
-```
-
-This will update corresponding package files, use `git diff` to see changes.
-
-If you've ran the command and curious about Debian version specifics, here's an
-explanation:
-Deb version will be `0.9.4~beta-1`. `~` (and not `-`) is required by packaging
-guidelines, and `-1` is Debian package revision for `0.9.4` upstream release. If
-a Debian-specific patch was later added on top of `0.9.4`, it'd be `-2` for the
-next Debian version. Rpm has a corresponding revision in its .spec file.
-
-# CI development
-
-S3 upload code is extracted to various files in `.ci`. It's possible to iterate
-locally by doing stuff like this:
-
-```
-bash -c '
-. .ci/upload.sh;
-prepare_upload_filename "bionic/kasmvncserver_0.9.1~beta-1+libjpeg-turbo-latest_amd64.deb";
-echo $upload_filename;'
-```
-
-# ARM
-
-KasmVNC is supported on ARM, however, the build process needs to be broken into two parts with one occuring on a x64 system and the other on an ARM system. All our testing and official builds are done on AWS Graviton instances.
-
-### Build www code on x86 System
-The www code is webpacked for performance and thus requires building. There are NPM packages, phantomjs, which do not have an ARM build. Therefore, this must be built on x86 and then copied over to the ARM system for final packaging.
-
-```
-cd ~/KasmVNC
-mkdir builder/www
-sudo docker build -t kasmweb/www -f builder/dockerfile.www.build .
-sudo docker run --rm -v $PWD/builder/www:/build kasmweb/www:latest
-cd builder
-tar -zcvf /tmp/kasm_www.tar.gz www
-```
-
-Now transfer ```kasm_www.tar.gz``` to the ARM system.
-
-### Build KasmVNC ARM
-These instructions assume KasmVNC has been cloned at $HOME and ```kasm_www.tar.gz``` has been placed at $HOME as well, adjust for your environment.
-
-```
-cd ~
-tar -zxf kasm_www.tar.gz -C KasmVNC/builder/
-cd KasmVNC
-sudo builder/build-package ubuntu bionic
-```
-The resulting deb package can be found under ~/KasmVNC/builder/build/bionic
-Replace ```bionic``` with ```focal``` to build for Ubuntu 20.04LTS. At this time, only Ubuntu Bionic has been tested, however, other Debian based builds we support should also work.
