# CSS Stress Test
This benchmarks bundler performance for CSS hot reloading.
## Results
bun is 14x faster than Next.js at hot reloading CSS.
```
bun v0.0.34
Saving every 16ms
Frame time:
50th percentile: 22.2ms
75th percentile: 23.9ms
90th percentile: 25.3ms
95th percentile: 43.6ms
99th percentile: 49.1ms
Rendered frames: 922 / 1024 (90%)
```
```
Next.js v11.1.2
Saving every 16ms
Frame time:
50th percentile: 312ms
75th percentile: 337.6ms
90th percentile: 387.7ms
95th percentile: 446.9ms
99th percentile: 591.7ms
Rendered frames: 64 / 1024 (6%)
```
## How it works
It times pixels instead of builds. `color-looper.zig` writes color updates and the timestamp to a css file, while simultaneously screen recording a non-headless Chromium instance. After it finishes, it OCRs the video frames and verifies the scanned timestamps against the actual data. This data measures (1) how long each update took from saving to disk up to the pixels visible on the screen and (2) what % of frames were rendered.
The intent is to be as accurate as possible. Measuring times reported client-side is simpler, but lower accuracy since those times may not correspond to pixels on the screen and do not start from when the data was written to disk (at best, they measure when the filesystem watcher detected the update, but often not that either). `color-looper.zig` must run separately from `browser.js` or the results will be inaccurate.
It works like this:
1. `browser.js` loads either bun or Next.js and a Chromium instance opened to the correct webpage
2. `color-looper.zig` updates [`./src/colors.css`](./src/colors.css) in a loop up to `1024` times (1024 is arbitrary), sleeping every `16`ms or `32`ms (a CLI arg you can pass it). The `var(--timestamp)` CSS variable contains the UTC timestamp with precision of milliseconds and one extra decimal point
3. `color-looper.zig` automatically records the screen via `screencapture` (builtin on macOS) and saves it, along with a `BigUint64Array` containing all the expected timestamps. When it's done, it writes to a designated file on disk which `browser.js` picks up as the signal to close the browser.
4. `ffmpeg` converts each frame into a black and white `.tif` file, which `tesseract` then OCRs
5. Various cleanup scripts extract the timestamp from each of those OCR'd frames into a single file
6. Using the OCR'd data, `./read-frames.js` calculates the 50th, 75th, 90th, 95th, and 99th percentile frame time, along with how many frames were skipped. Frame time is the metric here that matters here because that's how much time elapsed between each update. It includes the artificial sleep interval, so it will not be faster than the sleep interval.
The script `run.sh` runs all the commands necessary to do this work unattended. It takes awhile though. The slow part is OCR'ing all the frames.
To run this, you need:
- `zig`
- `bun-cli`
- `node`
- `tesseract`
- `screencapture` (macOS builtin)
- `ffmpeg`
- `puppeteer` (from the package.json)
You will need to run `bun bun --use next` first, with `next@11.1.2`. It will only run on macOS due to the dependencies on `screencapture`, how it detects screen resolution (so that Chromium is maximized), and how it auto-focuses Chromium (apple script)

# Benchmarking hot module reloading
## Methodology
How do you benchmark hot module reloading? What do you call "done" and what do you call "start"?
The answer for "done" is certainly not compilation time. Compilation time is one step.
I think the answer should be different depending on the type of content loaded.
For CSS, the answer should be "when the updated stylesheet was drawn on the screen"
For JavaScript, the answer should be "when the rebuilt code completed execution such that any changes are applied"
For images & assets, the answer should be "when the updated asset finished loading"
The start time should be defined as "the timestamp the filesystem set as the write time". As in, the time the developer pressed save in their editor.

# Hot Reload Files Stress Test
This is a stress test for Bun's hot reloading functionality, designed to test performance with a high number of interdependent files.
## What It Does
- Generates 1000 interconnected TypeScript modules
- Each module imports 2 other modules
- Uses IPC (Inter-Process Communication) to detect reloads
- Performs 1,000 hot reloads and tracks memory usage
- Reports statistics about hot reload performance
## Usage
```bash
./run-stress-test.sh
```
This will:
1. Generate 1000 interconnected modules
2. Run the stress test that performs 10,000 hot reloads
3. Report complete performance statistics
## How The Test Works
The test utilizes Node.js's child_process fork API for communication:
1. The main process (stress-test.ts) creates a child process running Bun with hot reloading
2. The modules communicate with the parent process via IPC when they're reloaded
3. After detecting a successful reload, the parent modifies another file
4. This continues for 1,000 iterations
5. Memory usage is tracked throughout the process
## Architecture
- **generate.ts**: Creates 1000 interconnected modules with IPC signaling
- **stress-test.ts**: Controls the test, forks Bun, and tracks metrics
- **run-stress-test.sh**: Script to run the entire test from scratch
## Performance Metrics
The test reports:
- Total number of hot reloads completed
- Time taken to complete all reloads
- Average time per reload
- Initial and final RSS memory usage

Unfortunately, the system API underneath (`getaddrinfo`) does not provide a way to get the TTL of a DNS entry. This means we have to pick a number arbitrarily.

# ASAN Builds for Bun
This document explains how to use and configure ASAN (Address Sanitizer) builds for Bun.
> **Note**: ASAN builds are available in CI for Linux and are configured to help identify memory issues in release builds.
## What is ASAN?
ASAN (Address Sanitizer) is a memory error detector for C/C++ and Zig code. It can detect:
- Use-after-free
- Heap buffer overflow
- Stack buffer overflow
- Global buffer overflow
- Use-after-return
- Use-after-scope
- Initialization order bugs
- Memory leaks
## ASAN Builds in CI
Bun CI includes ASAN builds to catch memory errors. These builds are configured with:
- Release optimizations for speed
- ASAN instrumentation for memory error detection
- Assertions enabled for both Bun and WebKit
The CI pipeline automatically:
- Builds a special ASAN-enabled release build for Linux
- Runs all tests to thoroughly check for memory issues
- Uses reduced parallelism to avoid memory pressure during testing
- Applies suppressions for known false positives
- Extends test timeouts to accommodate ASAN overhead
- Includes ASAN builds in release artifacts for debugging purposes
## Local ASAN Builds
To build Bun with ASAN locally, you can use the npm script:
```bash
# Build a release build with ASAN and assertions (recommended)
bun run build:asan
```
Or manually with CMake:
```bash
# Debug build with ASAN
cmake -B build -DCMAKE_BUILD_TYPE=Debug -DENABLE_ASAN=ON
# Release build with ASAN
cmake -B build -DCMAKE_BUILD_TYPE=Release -DENABLE_ASAN=ON
# Release build with ASAN and assertions
cmake -B build -DCMAKE_BUILD_TYPE=Release -DENABLE_ASAN=ON -DENABLE_ASSERTIONS=ON
```
## Running with ASAN
When running an ASAN build, you can configure behavior with environment variables:
```bash
# Basic ASAN options - leak detection disabled (recommended)
ASAN_OPTIONS=detect_leaks=0:halt_on_error=0:detect_odr_violation=0 ./build/bun-asan
# If you really need leak detection (will produce A LOT of noise)
# ASAN_OPTIONS=detect_leaks=1:leak_check_at_exit=1:halt_on_error=0 ./build/bun-asan
# LSAN_OPTIONS=suppressions=lsan.supp:print_suppressions=1 ./build/bun-asan
```
> **Warning**: Enabling leak detection will generate excessive noise due to deliberately uncollected memory in WebKit and other components. It's recommended to keep leak detection disabled and focus on other memory errors like use-after-free, buffer overflows, etc.
## Other Memory Error Types
ASAN can detect several types of memory errors:
1. **Use-after-free**: When a program continues to use memory after it's been freed
2. **Buffer overflow**: When a program writes beyond the bounds of allocated memory
3. **Stack overflow**: When a function's stack usage exceeds available space
4. **Memory corruption**: Often caused by writing to invalid memory locations
5. **Use-after-return**: When a function returns a pointer to stack memory that's no longer valid
When an error is detected, ASAN will print a helpful report showing:
- The type of error
- The memory address where the error occurred
- A stack trace showing the code path that led to the error
- Information about the memory allocation/deallocation (if relevant)
Example error output:
```
==1234==ERROR: AddressSanitizer: heap-use-after-free on address 0x614000000044 at pc 0x55d8e2ac1f14...
READ of size 4 at 0x614000000044 thread T0
#0 0x55d8e2ac1f14 in main example.c:10
#1 0x7f91e6f5e0b2 in __libc_start_main...
```
## Understanding ASAN Reports
ASAN reports contain detailed information about memory errors:
```
==12345==ERROR: AddressSanitizer: heap-use-after-free on address 0x7f7ddab8c084
READ of size 4 at 0x7f7ddab8c084 thread T0
#0 0x43b45a in Function source/file.cpp:123:45
#1 0x44af90 in AnotherFunction source/file.cpp:234:10
...
```
Key components of the report:
- Error type (heap-use-after-free, heap-buffer-overflow, etc.)
- Operation (READ/WRITE) and size
- Stack trace showing where the error occurred
- Information about the allocated/freed memory
## Best Practices
1. Run tests with ASAN builds regularly
2. Add suppressions only for well-understood false positives
3. Fix real issues promptly - ASAN errors indicate real problems
4. Consider using ASAN in debug builds during development
