Quick recipe for systems using apt
make prereqs # Install prequisites make # Build it make check # Run the tests
For higher performance, follow this with:
sudo apt remove golang make golang-current make clean make make check
This code is developed under Linux and expected to work under any other Unix, including OS X. Full function has been confirmed under MS-Windows/WSL, but native MS-Windows is not supported.
You will want 64-bit hardware. While this code passes its tests on 32-bit machines, they have an address space too small to be useful for surgery on large repositories. (32-bit build is tested with "make GOOS=linux GOARCH=386".)
You will need git at version 2.19.2 or later. Versions of reposurgeon after 4.7 assume the --show-original-ids option of git-fast-export is available.
You will need the Go compiler at revision 1.12 or later. It is recommended that you run with the most recent version of the Go compiler, as point releases often have GC performance improvements that are significant on reposurgeon’s workload.
Note that if you install a non-default version of golang under Debian-derived Linuxes you may have to tweak your $PATH variable to make the Go tools visible. To avoid this, the golang-current production enables the official Go backports PPA. This will always install the most recent compiler version; the last line reports it. Note that if you do this, the stock version-numbered golang packages carried by your distribution need not be installed.
hg-git-fast-import is required if you want to write Mercurial repositories, but not to read them. Note that this is not part of stock Mercurial, but does a better job of handling odd cases than the stock 'hg-fastimport' plugin.
A few scripts are written in shell. Any Bourne-shell-like implementation will do. The restricted shell shipped on Debian/Ubuntu will work. Shell is almost certainly already installed on your system.
You will need asciidoctor to format the documentation.
golint, shellcheck, mercurial, cvs, and rsync are required for the full regression tests, but not for running the code. The cvs-fast-export and Subversion svnadmin importer are also required for testing. Very old versions of Subversion (certainly 1.6 or earlier, but not 1.9 or later) will cause one spurious test failure.
gnuplot is only required if you’re planning to try performance-tuning with repobench.
Building the software
To build the tools, simply run "make" in the toplevel directory. This also builds the suite documentation.
Testing the software
There is an extensive regression-test suite in the
To test the correctness of this software once its prerequisites are
make check in the main directory.
Note to packagers
It probably is not necessary to package repobench, as it is a benchmarking tool only of interest to developers working with the source distribution.
