<h1>Out of Memory Analyser</h1>
<p>
    OOMAnalyser is a small project to transform the OOM message of a Linux kernel into a more user-friendly format.
</p>
<p>
    OOMAnalyser consists of a web page into whose input field the OOM message is copied. JavaScript code extracts
    the data from it and displays the details. All processing takes place in the browser. No data is transferred
    to external servers.

                The OOM killer was automatically triggered to free memory, because the system couldn't satisfy the
                memory request.
                The OOM killer calculates a score for each process and terminates the process with the highest score
                to satisfy the original memory request.

                by a user with root privileges. There is no demand to free memory but the OOM killer started
                nevertheless. The OOM killer calculates a score for each process and terminates the process with the
                highest score.

    Installing OOMAnalyser is quite easy since OOMAnalyser consists only of two files, a
    HTML file and a JavaScript file. Both can be stored locally to use OOMAnalyser
    without an Internet connection.

<h3>Installation steps</h3>
    <ol>
        <li>Download the <a download="OOMAnalyser.html" href="OOMAnalyser.html">HTML file</a> and the
            <a download="OOMAnalyser.js" href="OOMAnalyser.js">JavaScript file</a> to the main directory
        </li>
        <li>Open the file <code>OOMAnalyser.html</code> in your favourite browser.</li>

## Introduction

This is a forked version of [Carsten Grohmann's OOMAnalyser](https://git.sr.ht/~carstengrohmann/OOMAnalyser) targeting SUSE based operating systems.

It is a small project to transform the OOM message of a Linux kernel into a more user-friendly format.

OOMAnalyser consists of a web page into whose input field the OOM message is copied. JavaScript code extracts the data
from it and displays the details. All processing takes place in the browser. No data is transferred to external servers.
This makes it possible to use a locally stored copy of the website for analysis.

This project is written in [Python](https://www.python.org) and uses [Transcrypt](https://www.transcrypt.org/)  to
translate Python code into JavaScript.

The current online version is available at [https://www.carstengrohmann.de/oom/](https://www.carstengrohmann.de/oom/) .

## Installation

Installing OOMAnalyser is quite easy since OOMAnalyser consists only of two files, an HTML file and a JavaScript file.
Both can be stored locally to use OOMAnalyser without an Internet connection.

### Installation steps

1. Open [https://www.carstengrohmann.de/oom/](https://www.carstengrohmann.de/oom/) in a browser
 2. Browse down to the paragraph "Local Installation" at the end of the document
 3. Download the HTML file and the JavaScript file to the main directory
 4. Open the file `OOMAnalyser.html` in your favourite browser

## Building OOMAnalyser

### Requirements

* [Python](http://www.python.org) 3.7
 * [Transcrypt](https://www.transcrypt.org/) 3.7
 * [Rollup](https://rollupjs.org/)

### Prepare the build environment

* Clone the repository:

# git clone https://git.sr.ht/~carstengrohmann/OOMAnalyser

* Set up the Python virtual environment:

# virtualenv env
        # . env/bin/activate
        # env/bin/pip install -Ur requirements.txt

# make venv

### Build OOMAnalyser

```
# . env/bin/activate
# transcrypt --build --map --nomin -e 6 OOMAnalyser.py
# rollup --config rollup.config.mjs

# make build
```

### Usage

* Change into the source directory and start your own small web server.

* Start Python built-in web server:

# python3 -m http.server 8080 --bind 127.0.0.1

# make websrv

* Open the URL http://localhost:8080/OOMAnalyser.html in your favorite browser.

## Publish a new release
### Naming

* `NEW_VERSION` - Version string of the new version e.g. `0.5.0`
* `NEW_GIT_VERSION` - Git version string of the new version e.g. `v0.5.0`

### Steps
 1. Commit all open changes
 2. Updating the documentation in `README.md` and `OOMAnalyser.html` and commit changes

# git commit -m "Update documentation"

3. Update version number in `OOMAnalyser.py` and `Makefile`

# git commit -m "Bump version number to <NEW_VERSION>"

4. Create a new annotated git tag with shortened changelog

# git tag -a <NEW_GIT_VERSION>

5. Push changes into public repositories

# git push
        # git push origin --tags

6. Create release packages in zip and tar.gz format

# make release

7. Create release on SourceHut & GitHub

8. Start a new development cycle by setting new version numbers

## Resources

* [Transcrypt](https://www.transcrypt.org/)
 * [Linux man pages online](https://man7.org/)
 * [Decoding the Linux kernel's page allocation failure messages](https://utcc.utoronto.ca/~cks/space/blog/linux/DecodingPageAllocFailures)
