[meta-networking][PATCH 0/2] ncp - a fast file copy tool for LANs

[André Draszik]

"ncp" is a utility for copying files in a LAN. It has absolutely
no security or integrity checking, no throttling, no features,
except one:
  you don't have to type the coordinates of your peer.

Basically it works like this:

- You and your buddy want to play Quake
- Your buddy has a level that you don't have
- He types npush filename and waits. npush sends out UDP
  announcement packets proclaiming that someone wants to
  send something
- You type npoll. npoll waits until it sees one of these packets
- The files are copied with tar over a TCP socket, so permissions
  and file dates (and if you are root, owners) are preserved
- There are other usage modes. You can also use it like this:

  peer1$ ncp
                           peer2$ ncp peer1 file1 file2 file3
or like this:

  peer1$ npush file1
                           peer2$ npoll peer1

Is setting CC etc. on make cmdline really needed ?
may be just adding the -I flags to CPPFLAGS is enough ?

not needed if you can just do

install -D -m 0755 ncp ${D}${bindir}/ncp

and avoid two calls to install ( one for dir and another for file )

same here not needed.

Yes, the Makefile sets CC CFLAGS LDFLAGS excplicitly, so make doesn't
inherit them from the environment variables, because OE doesn't pass the -e
make flag anymore. https://www.gnu.org/software/make/manual/html_node/Enviro
nment.html#Environment

> may be just adding the -I flags to CPPFLAGS is enough ?

It doesn't respect CPPFLAGS, but an alternative would be:

EXTRA_OEMAKE = "\
    DIET= \
    DEBUG=nostrip \
    -e \
"
CFLAGS_append = " -I${STAGING_INCDIR}/libowfat"

I have no preference either way, but my original version makes it more
obvious what we're after.

Using -D that'd still need two calls, as multiple files are being copied and
-D only allows you to specify one destination (I think). Not really gaining
anything here. In addition, you have to specify the source filename multiple
times (in src and destination).
This:
    install -d -m0755 ${D}${mandir}/man1
    install -m0644 ncp.1 npush.1 ${D}${mandir}/man1
vs.
    install -D -m0644 ncp.1 ${D}${mandir}/man1/ncp.1
    install -D -m0644 npush.1 ${D}${mandir}/man1/npush.1

but 4 install calls will be reduced to two.

I am not sure I agree. This means one could accidentally override make
variables. Being explicit as in the original version is more deterministic.
Otherwise somebody would have to audit each recipe's makefile once a
variable is added or removed from the bitbake environment. That doesn't
scale. It would appear that the -e flag was removed from EXTRA_OEMAKE in rev
aeb653861a0ec39ea7a014c0622980edcbf653fa for a similar reason... Even the
make manual recommends against using -e.

-e is bad for some reason It missed my eye last time so I agree on -e part
my suggestion was mainly on CC and CFLAGS being passed in makefile options
it seems the package Make infra needs a patch for this to work cleanly.

Hm, hold on. Something went wrong along the way. I can't actually install it
anymore:
