Resource Tracer project

Description

• A resource tracing, debugging and profiling tool
• Restracer@github

Crossplatform method to trace software errors in runtime during resource manipulation is shown. A scheme for describing abstract resources and their functions in XML is presented. Due to separation it’s possible to describe vast classes of resources without changing the analyzer core. Detected errors often have an influence on security, safety, robustness and resource optimal usage.

Supported build tools

• GNU Make
• BSD Make

Install

Gentoo (stage3 or stage3+)

• sudo sh -c 'echo 92.63.64.5 skylark.tsu.ru >> /etc/hosts'
• export GPG_KEY=B0414424; export DISTRO_TARBALL_NAME=restracer-current-linux-amd64.tar.xz; export DISTRO_TARBALL_ASC_NAME=$DISTRO_TARBALL_NAME.asc
• gpg --keyserver hkp://pgp.mit.edu --recv-keys $GPG_KEY || gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys $GPG_KEY || gpg --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-keys $GPG_KEY
• wget http://skylark.tsu.ru/art/master/$DISTRO_TARBALL_NAME
• wget http://skylark.tsu.ru/art/master/$DISTRO_TARBALL_ASC_NAME
• gpg --verify $DISTRO_TARBALL_ASC_NAME
• sudo tar xf $DISTRO_TARBALL_NAME -C /usr --skip-old-files

Other OS/distros

System-wide

• git clone https://github.com/larkvirtual/restracer.git
• cd restracer
• cat DEPENDS.txt
• make -j$(nproc)
• sudo make install

  User-only

• git clone https://github.com/larkvirtual/restracer.git
• cd restracer
• cat DEPENDS.txt
• make -j$(nproc)
• DESTDIR=usr-local make install

Use

Userspace (CLI/Daemon applications)

• System-wide: no extra commands needed
• User-only: export PATH=$PATH:PATH-TO-RESTRACER/usr-local/bin; export RT_ROOT=PATH-TO-RESTRACER/usr-local

  Networked method (traced application writes to socket, analyzer runs in the same time)

• cd src
• Put art_start("myApp;autostart;"); call is a first function inside your main()
• GNU Make@GNU/Linux: rt-make
• GNU Make@FreeBSD: rt-gmake
• BSD Make@FreeBSD: rt-make
• restracer ./myApp

  Pros

• Analyzer (artrepgen) can run on some remote location, outside of traced program / container

  Cons

• Less easy to debug restracer itself
• Network throughput performance may be primary importance

Tracefile method (traced application writes to tracefile, then finishes noramally or not, then passing tracefile to analyzer)

• cd src
• Put art_start(""); call is a first function inside your main()
• GNU Make@GNU/Linux: RT_TEMPLATE=posix-gcc-mt-file-lint rt-make
• GNU Make@FreeBSD: RT_TEMPLATE=posix-gcc-mt-file-lint rt-gmake
• BSD Make@FreeBSD: RT_TEMPLATE=posix-gcc-mt-file-lint rt-make
• restracer ./myApp
• artrepgen --file tracefile.out

  Pros

• More easy to debug restracer itself
• Less tricky to run Analyzer (artrepgen)

  Cons

• Can consume lots of diskspace
