Commit Briefs
Add error injection that kills caller (errinj_kill_caller)
Closes #28
Add configuration support
Patch adds command line options and configuration file support to unreliablefs. unreliablefs can be managed in runtime using simple .INI configuration file. unreliablefs config uses configuration language which provides a structure similar to what's found in Microsoft Windows INI files or used by configparser Python module [2]. To make it possible third-party C library [1] has been imported. There is only one supported error injection - "errinj_noop" that replaces file operation with no operation. More error injections are coming. 1. https://github.com/benhoyt/inih 2. https://docs.python.org/3/library/configparser.html Closes #3 Closes #18 Closes #1 Closes #7 Closes #12 Closes #60
cmake: add ASAN and UBSAN sanitizers
Disabled by default
cmake: set CFLAGS using target_compile_options()
Using target_compile_options() is one of the best practice for CMake so replaced CMAKE_C_FLAGS and CMAKE_CXX_FLAGS by target_compile_options(). Also patch adds options -Wall and -Wextra.

## UnreliableFS [![Build Status](https://api.cirrus-ci.com/github/ligurio/unreliablefs.svg)](https://cirrus-ci.com/github/ligurio/unreliablefs) is a FUSE-based fault injection filesystem that allows to change fault-injections in runtime using simple configuration file. Supported fault injections are: - `errinj_errno` - return error value and set random errno. - `errinj_kill_caller` - send SIGKILL to a process that invoked file operation. - `errinj_noop` - replace file operation with no operation (similar to [libeatmydata](https://github.com/stewartsmith/libeatmydata), but applicable to any file operation). - `errinj_slowdown` - slowdown invoked file operation. ### Building Prerequisites: - CentOS: `dnf install -y gcc -y cmake fuse fuse-devel` - Ubuntu: `apt-get install -y gcc cmake fuse libfuse-dev` - FreeBSD: `pkg install gcc cmake fusefs-libs pkgconf` - OpenBSD: `pkg_add cmake` - macOS: `brew install --cask osxfuse` ```sh $ cmake -S . -B build -DCMAKE_BUILD_TYPE=Debug $ cmake --build build --parallel ``` ### Packages [![Packaging status](https://repology.org/badge/vertical-allrepos/fusefs:unreliablefs.svg)](https://repology.org/project/fusefs:unreliablefs/versions) ### Using ```sh $ mkdir /tmp/fs $ unreliablefs /tmp/fs -basedir=/tmp -seed=1618680646 $ cat << EOF > /tmp/fs/unreliablefs.conf [errinj_noop] op_regexp = .* path_regexp = .* probability = 30 EOF $ ls -la $ umount /tmp/fs ``` ### Documentation See documentation in [unreliablefs.1](https://ligurio.github.io/unreliablefs/unreliablefs.1.html) and [unreliablefs.conf.5](https://ligurio.github.io/unreliablefs/unreliablefs.conf.5.html). ### License MIT License, Copyright (c) 2020-2023, Sergey Bronnikov BSD-3-Clause, Copyright (C) 2009-2020, Ben Hoyt
