Change subject: IMPALA-8737: Patch gperftools to implement O(log n) searching for PageHeap::AllocLarge() ...................................................................... IMPALA-8737: Patch gperftools to implement O(log n) searching for PageHeap::AllocLarge() In gperftools 2.5, PageHeap::AllocLarge() has O(n) behavior. This patches gperftool 2.5 to incorporate the patches that change PageHeap::AllocLarge() to have O(log n) searching: https://github.com/gperftools/gperftools/commit/06c9414ec423ffe442c047b2560555f9d5847b1d https://github.com/gperftools/gperftools/commit/f1d3fe4a21e339a3fd6e4592ee7444484a7b92dc This also adds a build for gperftools 2.8.1 to allow future development/testing for actually upgrading gperftools (IMPALA-6784). Testing: - Ran a toolchain build with this - Ran Impala locally with the resulting gperftools-2.5-p4 Change-Id: I7f41f2d296e26e160fd9bcc8be29085d1e9a8bc2 --- M buildall.sh A source/gperftools/gperftools-2.5-patches/0003-Implemented-O-log-n-searching-among-large-spans.patch A source/gperftools/gperftools-2.5-patches/0004-refactored-handling-of-reverse-span-set-iterator-for.patch A source/gperftools/gperftools-2.8.1-patches/0001-Port-gperftools-to-adapt-aarch64.patch 4 files changed, 873 insertions(+), 1 deletion(-) git pull ssh://gerrit.cloudera.org:29418/native-toolchain refs/changes/82/17482/1 -- To view, visit http://gerrit.cloudera.org:8080/17482 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: native-toolchain Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: I7f41f2d296e26e160fd9bcc8be29085d1e9a8bc2 Gerrit-Change-Number: 17482 Gerrit-PatchSet: 1 Gerrit-Owner: Joe McDonnell <joemcdonn...@cloudera.com>
