# chattymalloc - a high-performance shared library based malloc tracer
## Dependencies
* meson
* (clang-format, clang-tidy, yapf)
## Compilation
Clone the repository.
`git clone https://muhq.space/software/chattymalloc.git`
Build chattymalloc by running `make` in the repository root.
## Usage
chattymalloc is designed to be used with the LD_PRELOAD mechanism.
It hooks the memory allocator API and saves each allocator call and its result
to a memory mapped binary file, called chattymalloc.trace, which will be stored to the current directory.
`env LD_PRELOAD=/path/to/libchattymalloc.so <your-binary>`
The resulting binary trace file can be parsed and the results plotted using
chattyparser.py.
# chattyparser - a parser and plotter for chattymalloc trace files
chattyparser parses a trace file, detects allocator and application misbehavior,
like double frees, produces a plain text trace, a histogram and a memory profile.
## Usage
usage: chattyparser.py [-h] [--alignment ALIGNMENT ALIGNMENT] [--txt] [-v]
[--license]
