Hi David,

Following is what I am getting [1] with compiler version:
gcc (GCC) 10.1.1 20200511

.../dpdk/lib/librte_hash/rte_cuckoo_hash.c: In function
‘__rte_hash_add_key_with_hash’:
.../dpdk/lib/librte_hash/rte_cuckoo_hash.c:1104:29:

Ah.
I just saw that my fedora (rawhide) did not have this version yet...
upgraded and I reproduce the issue.
gcc version 10.1.1 20200507 (Red Hat 10.1.1-1) (GCC)

Kevin confirmed that fc32 switched to 10.1.1 version too.


Thanks.

The return value of rte_ring_sc_dequeue_elem() is checked, but gcc
seems to find some possibility of ext_bkt_id not being initialized.

It was introduced with commit [1], but I guess the tools wouldn't have
found it at time of commit.

zero is an invalid value for ext_bkt_id, so we can just initialize to
that and check it is overwritten. Sent patch

Hi,

Please let's discuss the dates for the next release cycle.

>   * Integration/Merge/RC1:	Tuesday, 14 July 2020

I prefer a target at the very beginning of the month,
it is an insurance against disaster,
and it may allow a quiet August month for the maintainers.

Another issue is the delay between -rc1 and final release.
The above proposal has only 24 days -rc phase.
Based on records, we need 30 days for a proper -rc phase.

Taking above requirements into consideration,
I propose having a proposal deadline earlier by 8 days:

- Proposal deadline: Monday, 8 June 2020
- Integration deadline: Tuesday, 30 June 2020
- 20.08-rc1: Friday, 3 July 2020
- 20.08-rc2: Friday, 17 July 2020
- 20.08-rc3: Friday, 24 July 2020
- 20.08-rc4: Friday, 31 July 2020
- Release: Monday, 3 August 2020

Personally I think the original proposal deadline and release
plan was good. But this is a valid argument to give sufficient
days for the rc phase.
Also the release of 20.08 early in August can also give
a big enough window for the 20.11 release.
So +1 for the new schedule.

I think the proposal deadline should be left at Tuesday 16 June, as developers have been working towards this date.
I am ok with the other dates.

Bernard.
