Hiya, I'm Dumpy.
I'm the crash assistant and my job is to help you with your (crash) dumps.
β§ο½₯οΎ: * β¦ . ο½₯οΎ
Dumpy is a Web application that digests dumps from applications that have either π₯ crashed π₯ or simply decided to take a dump. β¨ These dumps contain a trove of data about the running (or not running) state of an application, such as:
Dumpy formats and displays all this information in an interactive and purpose-built interface. Whether you need to skim the important bits quickly or dive deep into a dump, Dumpy can help you with your dumps. π
First and foremost, Dumpy is not a completed project. Much of Dumpy's potential is still to be realized. Still, Dumpy is already helpful enough to
When you give a precious dump to Dumpy, that dump isn't uploaded anywhere. Dumpy is powerful enough to parse and analyze your dump on your own machine. Dump parsing is powered by a WebAssembly module written in Rust.
Currently, the only dump format supported is the minidump format, used by Google Chrome/Chromium, Firefox, and Windows, among others. In particular, the library Dumpy uses to process minidump files supports the dumps produced by the MinidumpWriteDump
API on Windows as well as the Google Breakpad library.[^1]
[^1]: Supported formats according to the minidump crate as of 2023 April 16.
If you need a sample file to test with, I've included one in this repo! π I have 'borrowed' this dump from the rust-minidump project's test files.
You can try the online demo. If you need one, you can use this sample dump file.
What you'll need:
Grab your copy of this repository
$ git clone https://github.com/clavin/Dumpy.git
$ cd Dumpy
Install the project build dependencies
$ npm install
Build the dump processor crate
$ cd crate
$ wasm-pack build
$ cd ..
Build the web app
$ npm run build
# (If you need to specify any additional Vite options, like `--base`, this is
# the place to do it.)
Enjoy! The web app is available in the dist/
directory. π
npm run dev
command for an ergonomic web development workflow.
