metastore

metastore is a tool to store the metadata of files/directories/links in a file tree to a separate file and to later compare and apply the stored metadata to said file tree.

It was originally written as a supplement to git, which does not store all metadata, making it unsuitable for e.g. storing /etc in a repository.

metastore can also be helpful if you want to create a tarball of a file tree and make sure that "everything" (e.g. xattrs, mtime, owner, group) is stored along with the files.

Stored metadata

metastore stores following metadata in its files:

owner,
group,
permissions,
xattrs,
mtime - optionally.

Usage

See metastore.txt file, which is plain-text version of the manual page.

If you want to use metastore within git repository, then consider copying exemplary scripts from examples/hooks/ directory to hooks subdirectory in your git directory, and make them executable. You can also tune them if it's necessary. But. Before using, please read the warning in the comments of pre-commit hook. Mind that merge conflicts can only be solved manually, because metastore file is binary in its current form (there's a plan to fix it in future). Dump action can be really helpful in such cases.

File format

See FILEFORMAT file, which describes internals of metastore file.

Requirements

Linux
GNU make
C99 compiler, like gcc or clang
libbsd

Building

Simply run make from project's root directory.

Building out-of-tree is supported out-of-the-box. Go to your chosen build directory and run there:

$ make -f path/to/metastore/Makefile

Installation

Run make install. Default settings for installation are:

 PREFIX      = /usr/local

 EXECPREFIX  = ${PREFIX}
               (/usr/local)
 BINDIR      = ${EXECPREFIX}/bin
               (/usr/local/bin)
 DATAROOTDIR = ${PREFIX}/share
               (/usr/local/share)
 DOCDIR      = ${DATAROOTDIR}/doc/metastore
               (/usr/local/share/doc/metastore)
 MANDIR      = ${DATAROOTDIR}/man
               (/usr/local/share/man)

You can always change them, e.g.:

$ make install PREFIX=/usr

DESTDIR is also supported.
