* Note that due to the capability exchange via JSON-RPC and the state storage via JSON
|
|
* the bitmask numbers are stored in IEEE 754 64-bit floats.
|
|
* The latter have 53 digit bits which limit the bitmask.
|
|
* Not to run out of bits:
|
|
*
|
|
* Once all Icinga versions which don't have a specific capability are completely EOL,
|
|
* remove the respective capability checks and assume the peer has the capability.
|
|
* Once all Icinga versions which still check for the capability are completely EOL,
|
|
* remove the respective bit from icinga::Hello.
|
|
* Once all Icinga versions which still have the respective bit in icinga::Hello
|
|
* are completely EOL, remove the bit here.
|
|
* Once all Icinga versions which still have the respective bit here
|
|
* are completely EOL, feel free to re-use the bit.
|
|
*
|
|
* completely EOL = not supported, even if an important customer of us used it and
|
|
* not expected to appear in a multi-level cluster, e.g. a 4 level cluster with
|
|
* v2.11 -> v2.10 -> v2.9 -> v2.8 - v2.7 isn't here
