bgpreader: capture timestamp is printed as float #94

Closed cmosig closed 5 years ago

cmosig commented 5 years ago

The lastest version from this repository prints the record-ts as float. I did a normal install:

$ ./autogen.sh
$ ./configure
$ make

Sample query:

libbgpstream/tools/bgpreader -t updates -w 1566000000

output:

It seems like you are running BGPStream v2, which is found in the libbgpstream GitHub repo (https://github.com/caida/libbgpstream). BGPStream v2 uses float values because some of the new data sources it supports have sub-second precision.

Are you sure that you cloned this repo (bgpstream) rather than libbgpstream?

I just tried cloning this repo and it prints integers as expected:

$ git clone git@github.com:caida/bgpstream.git
$ cd bgpstream/
$ ./autogen.sh
$ ./configure
$ make
$ ./tools/bgpreader -t updates -w 1566000000

Yes I am sorry. I confused the repositories.

Are the timestamps also going to be floats in this repository at some point?

alistairking commented 5 years ago

No, this repository will eventually superceded by the libbgpstream and pybgpstream repos. We will continue to maintain v1 (this repo) for the time being, but eventually it will be deprecated.
