[build] address compilation warnings from GCC 8.3.1
While compiling on CentOS 8.1 with GCC 8.3.1, the following warnings
were observed:
src/kudu/util/env_posix.cc:1523:11: warning: unnecessary parentheses in
declaration of ‘paths’ [-Wparentheses]
char *(paths[]) = { name_dup.get(), nullptr };
src/kudu/tablet/concurrent_btree.h: In instantiation of ‘void
kudu::tablet::btree::CBTreeIterator<Traits>::SeekToLeaf(const kudu::Slice&)
[with Traits = kudu::tablet::btree::SmallFanoutTraits]’:
src/kudu/tablet/concurrent_btree.h:1624:5: required from ‘bool
kudu::tablet::btree::CBTreeIterator<Traits>::SeekAtOrAfter(const kudu::Slice&,
bool*) [with Traits = kudu::tablet::btree::SmallFanoutTraits]’
src/kudu/tablet/cbtree-test.cc:502:5: required from here
src/kudu/tablet/concurrent_btree.h:1792:15: warning: ‘void* memcpy(void*,
const void*, size_t)’ writing to an object of type ‘class
kudu::tablet::btree::LeafNode<kudu::tablet::btree::SmallFanoutTraits>’ with no
trivial copy-assignment [-Wclass-memaccess]
memcpy(&leaf_copy_, leaf, sizeof(leaf_copy_));
~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
src/kudu/tablet/concurrent_btree.h:677:7: note: ‘class
kudu::tablet::btree::LeafNode<kudu::tablet::btree::SmallFanoutTraits>’ declared
here
class LeafNode : public NodeBase<Traits> {
This patch fixes the former and squelches the latter with a pragma to
ignore the -Wclass-memaccess warning.
This patch doesn't contain any functional modifications.
