Fossil is a distributed version control and ticket tracking system created by D. Richard Hipp, the primary author of SQLite. Features: - tamper-proof artifact record - simple command-line interface - customizable web interface with JSON, RSS, CGI, wiki, and forum - online project documentation with full-text search capability - integrated PIC-like markup language for creating diagrams - online activity and ticket reports - user accounts with access controls - coherent versioning across all files - straightforward branching and merging - bisect searches to pinpoint behavior changes - SHA3-256 and hardened SHA1 checksums - FUSE filesystem makes all historical and branch revisions available - synchronization via http, https, ssh, and local/network filesystems - automated replication and backup - git import/export and Subversion/CVS import - nested checkouts to share common subtrees across related projects - checkout directory not cluttered with administrative files - support for Docker - unversioned file area for builds, statistics, other ephemeral content - optional PGP signing of commits - users can subscribe to email alerts to be notified of event types - private branch which are excluded from syncs until published - bundles group a change set (e.g. a private branch) into a single file - users can make their own repositories, no need for special privileges - works in Windows as well as Linux and other Unix-like systems Fossil can host the entire project development website, including the download area, but it also can be used for individual projects with no need for a shared server. In addition to typical software development operations, one interesting application is coordination and auditing of /etc and other configuration files across a network of computers. Content is stored in an SQLite database for atomicity, durability, and effortless administration. See Fossil in action online: - https://fossil-scm.org/ - Fossil hosts its own development - https://sqlite.org/src/ - Fossil originally created to manage SQLite - https://core.tcl.tk/tcl/timeline?y=ci - Tcl/Tk migrated from CVS - https://chiselapp.com/ - Free public hosting for Fossil projects Key technical points: - unified revision history tree spans the entire repository - repository is a collection of artifacts identified by their checksums - artifacts are broadly grouped into content and structural artifacts - each check-in is tracked as a structural artifact known as a manifest - manifests primarily list the full names and checksums of each file - manifests can be amended by subsequent control artifacts - in most cases, symbolic names refer to the latest matching check-in - branches are implemented using propagating symbolic tags ------------------------------------------------------------------------ This SlackBuild script installs not only release versions of Fossil but also arbitrary development versions. If the current directory contains a file named "fossil-src.tar.gz", it is used as the source archive, and the check-in timestamp is used as the version string. For example, the package name could be "fossil-20200320T040201-x86_64-1_SBo.tgz". To download the latest trunk development version of Fossil, type: $ wget https://fossil-scm.org/home/tarball/fossil-src.tar.gz To download a specific version of Fossil, type: $ wget https://fossil-scm.org/home/tarball/$VERSION/fossil-src.tar.gz For more information about the allowable $VERSION formats, see: https://fossil-scm.org/home/doc/trunk/www/checkin_names.wiki
