Reading archive files

The Fluxzy file format (with extension fxzy) is an ad hoc file format designed to optimize the storage of PCAPNG data and to ensure rapid I/O throughout capture sessions. Unlike formats such as HAR, which uses JSON and can potentially slow down I/O operations due to its verbosity, Fxzy aims to minimize overhead and maximize efficiency during data captures.

To store request and response headers, Fxzy leverages mpack, a binary serialization format, with LZR compression enabled. This choice is grounded in mpack’s capacity for compact data representation and our implementation utilizes MessagePack-CSharp. This ensures the format is not only efficient in terms of space but also robust and reliable for varied use-cases encountered during debugging sessions with Fluxzy.

During an active capture session, fluxzy dumps collected web datas into aa temporary directory. The fluxzy file is just a compressed version of this directory.

The interface IArchiveReader specify the common read operation of any fluxzy archive input.

You can use DirectoryArchiveReader to read from dump directory.

var reader = new DirectoryArchiveReader("path/to/directory");

// call subsequent method to retrieve a particular exchange or connection

You can use FxzyArchiveReader to read from a fxzy file.

var reader = new FxzyArchiveReader("path/to/fxzy/file");

// call subsequent method to retrieve a particular exchange or connection

Fluxzy does not contains native way to parse immediatly an HAR file. Instead, it has an interface where you can convert the HAR file the fluxzy format directory.
