Estimate distinct count of values from standard input. Provides a very fast way to perform unique count estimates on the command line.
The edcount program implements HyperLogLog, with some minor modifications, as detailed by by Flajolet et. al. in the paper "HyperLogLog: the analysis of a near-optimal cardinality estimation algorithm".
Additionally, the memory footprint of the program is constant, at a few megabytes. This memory use is constant regardless of the number of records counted, and does not degrade in accuracy.
NOTE: this is my first attempt at a new port from scratch, please be kind.
Nice work and congratulations on your first port Marcel!
At a cursory glance it appears good, but the best way is to confirm that ones changes pass QA using our automated tools (portlint, poudriere at least), which pick up many issues
For details and instructions, see:
If you need help and pointers getting these up and running, jump on #freebsd-ports on freenode IRC where there's plenty of people to support you
We also have a whole bunch of cheatsheets and checklists for Issue Management (and Ports Issues in particular, which are available here:
If you need any clarity on any of that, #freebsd-bugs or #freebsd-ports again for pointers/clarifications (and we'll up date the docs to improve them)
Oh, I should have mentioned that I have already set up Poudriere to test the build as documented. This really streamlines the testing and gives helpful pointers on what to fix. :)
Ahh awesome :)
For future reports, you can mention that explicitly in your description:
portlint: OK (looks fine.)
testport: OK (poudriere: <versions>, <archs>, <OPTIONS> tested)
Okay, so just add those lines to the comment?
