[jira] [Updated] (QPID-5487) [linearstore] Replace use of
/dev/urandom with c random generator calls
[ https://issues.apache.org/jira/browse/QPID-5487?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kim van der Riet updated QPID-5487:
-----------------------------------
Description:
The use of /dev/urandom for random numbers is considered unfriendly to other systems on a machine that might depend upon this source.
The current use-case is for Journal serial numbers; the randomness of the C rand() call should be good enough, but it requires a 64-bit number. Construct this using several smaller numbers from rand() or random()

The current use-case is for Journal serial numbers; the randomness of the C rand() call should be good enough, but it requires a 64-bit number. Construct this using two 32-bit numbers.
