I disagree. If you define an alloc it is only reciprocal that you should define a free.
The code in question that hit this was changed (its in a version of rack that has the rate-limit and TLS code).. but I think these things *should* be balanced.. if you provide an Allocate, you should also provide a Freeā¦ R > On Feb 13, 2019, at 12:09 PM, John Baldwin <j...@freebsd.org> wrote: > > On 2/13/19 6:57 AM, Randall Stewart wrote: >> Author: rrs >> Date: Wed Feb 13 14:57:59 2019 >> New Revision: 344099 >> URL: https://svnweb.freebsd.org/changeset/base/344099 >> >> Log: >> This commit adds the missing release mechanism for the >> ratelimiting code.
