This commit adds a list of request types that do not have
parameters. These reqeusts are handled different by the JS code, and
the list makes it easier to add new custom commands that do not have
arguments.
BIRD-LG currently keeps log files indefinitely. This patch allows
setting the number of days logs should be kept for by adding
a `LOG_NUM_DAYS` parameter in the configuration files.
This change is backwards compatible: Running the updated code with
old configuration files will keep logs indefinitely as before; new
deployments based on the example configuration will keep logs
indefinitely.
Commit eaf531eee2 ("Correctly parse aspath for both bird 1.x and 2.0.")
inadvertently made a regexp more strict, and it no longer matches some
interface names. Example include `eth1.945` (tagged VLAN, which is a
common use-case for routers) or `br-foo`.
As a result, the regexp would not parse the "peer protocol name" that is
normally displayed on the bgpmap.
Fixes: #64
Without this patch, `show route where net ~ [ prefix+ ] (bgpmap)` erroneously returns only one prefix with a box shape, and all the other prefixes with a oval shape as if they were multipath intermediate ASes.
Bird displays neighbor's 4-byte AS capability as `AS4`.
This patch prevents it from being treated as an clickable ASN in the output of `show protocols <protocol_name> all` response.
Due to the change in the output of `show route for <prefix> all` since bird-2.0, this patch is necessary to correctly parse aspaths.
Without this patch, `build_as_tree_from_raw_bird_ouput()` fails with the following exception if the backend is bird-2.0.
