From 23829ebb09cfa016044f6e5a0b361de1e04705ad Mon Sep 17 00:00:00 2001 From: moneromooo-monero Date: Tue, 20 Nov 2018 15:24:16 +0000 Subject: mlocker: don't throw from lock/unlock This prevents exceptions from showing up in various awkward places such as dtors, since the only exception that can be thrown is a lock failure, and nothing handles a lock failure anyway. --- contrib/epee/src/mlocker.cpp | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'contrib/epee/src/mlocker.cpp') diff --git a/contrib/epee/src/mlocker.cpp b/contrib/epee/src/mlocker.cpp index c3262e8f4..7ac79bd9a 100644 --- a/contrib/epee/src/mlocker.cpp +++ b/contrib/epee/src/mlocker.cpp @@ -113,6 +113,8 @@ namespace epee void mlocker::lock(void *ptr, size_t len) { + TRY_ENTRY(); + size_t page_size = get_page_size(); if (page_size == 0) return; @@ -123,10 +125,14 @@ namespace epee for (size_t page = first; page <= last; ++page) lock_page(page); ++num_locked_objects; + + CATCH_ENTRY_L1("mlocker::lock", void()); } void mlocker::unlock(void *ptr, size_t len) { + TRY_ENTRY(); + size_t page_size = get_page_size(); if (page_size == 0) return; @@ -136,6 +142,8 @@ namespace epee for (size_t page = first; page <= last; ++page) unlock_page(page); --num_locked_objects; + + CATCH_ENTRY_L1("mlocker::lock", void()); } size_t mlocker::get_num_locked_pages() -- cgit v1.2.3
