Parallel Files Compressor

Given a source directory, the program performs recursive and parallel compression of all files belonging to the source directory and its subdirectories using bzip2.

The program has a result equivalent to the following sequence of commands:

$ cp -ax SOURCE_DIR DEST_DIR.bz2
$ cd DESTINO.bz2
$ find . -type f -exec bzip2 "{}" \;
$ cd ..
$ tar cf DEST_DIR.bz2.tar DEST_DIR.bz2
$ rm -rf DEST_DIR.bz2

Implementation

A pool of consumer is used, this is a set of threads(8) that perform the function of compressing the files with bzip2. The pool consumes a buffer with the files. The pool of producers is responsible for producing this buffer, that is, browsing the source directory, opening the source file and creating the destination file feeding the buffer. The final directory is compressed with tar.

How To Use

Compile the program with:

$ gcc -o bin -lpthread compressor.c

Execute the binary with:

$ ./bin <source_directory> <destination_directory>.bz2.tar
