I am pleased to announce NNCP 7.7.0 release availability!
NNCP (Node to Node copy) is a collection of utilities simplifying
secure store-and-forward files and mail exchanging.
This utilities are intended to help build up small size (dozens of
nodes) ad-hoc friend-to-friend (F2F) statically routed darknet
delay-tolerant networks for fire-and-forget secure reliable files, file
requests, Internet mail and commands transmission. All packets are
integrity checked, end-to-end encrypted (E2EE), explicitly authenticated
by known participants public keys. Onion encryption is applied to
relayed packets. Each node acts both as a client and server, can use
push and poll behaviour model. Also there is multicasting areas support.
Out-of-box offline sneakernet/floppynet, dead drops, sequential and
append-only CD-ROM/tape storages, air-gapped computers support. But
online TCP daemon with full-duplex resumable data transmission exists.
------------------------ >8 ------------------------
The main improvements for that release are:
* Experimental "kqueue" and "inotify" based notifications support
about spool directory changes, for reducing their often reading
overhead.
* ".seen" and ".hdr" files moved to "seen/" and "hdr/"
subdirectories, for faster scanning of spool directories. Current
files migration required:
$ find $NNCPSPOOL -type f -name "*.hdr" -exec rm {} +
$ find $NNCPSPOOL -type d -name rx | while read rx ; do
cd $rx
mkdir -p seen
find . -type f -name "*.seen" | while read fn ; do
mv $fn seen/${fn%.seen}
done
done
$ find $NNCPSPOOL -type d -name area | while read area ; do
find $area -type f -name "*.seen" | while read fn ; do
mv $fn ${fn%.seen}
done
done

Hi Sergey!
Thank you for this release.
Unfortunately, so far on Linux, I'm not seeing any change in the
pattern for nncp-call(er) while connected. I'm happy to debug
this if I can be of help.

I did not notice CPU usage drop too on my FreeBSD system. However it
should not list directory all the time -- so should be better on spools
with huge number of files. I just use fsnotify library -- all kqueue (or
inotify) work is done in it.

Hi Sergey,
OK, yes, you are right. I'm not seeing those scans in my straces
anymore. Nice!
I am still seeing a lot of nanosleep(), futex(), and
reading/writing down a pipe. I'm not sure if this is something to
do with Go's channels or something? (Just a guess)
- John
