* WT-3297 support the gcc/clang -fvisibility=hidden flag (#3404)Keith Bostic2017-06-191-3/+1

* WT-2402 Pad structures to avoid cache line sharing. (#3191)Michael Cahill2016-12-151-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * WT-2402 Pad structures to avoid cache line sharing. We previously used compiler alignment to avoid cache line sharing, which is problematic because we don't allocate memory with the necessary alignment, so some behavior is undefined. Instead, this change merely pads structs to ensure they won't share a cache line when allocated in an array. * Add some #if barriers around the new union's * Change where CACHE_LINE_PAD defines live and rename _START to _BEGIN * Add ax_check_compile_flag to aclocal * Lint * Allocate the TINFO structures separately to minimize false sharing. * Comment cleanup to make spell happy. * Pad the read-write locks to avoid false sharing. * Add a comment as to why we're adding -std=c11 to the compile. * whitespace * Add asserts that we're padding the structures we intended to pad. Minor cleanup, don't use #defines outside of the WiredTiger namespace.
* WT-2527: OS X compile error, missing POSIX_FADV_WILLNEED #defineKeith Bostic2016-04-011-11/+0
| | | | | OS X needs fake POSIX_FADV_XXX #defines as well as Windows, move them to os.h.
* WT-2330: in-memory configurations should not create on-disk collection filesKeith Bostic2016-03-261-0/+11
| | | | | | | | | | | | | | | | | | | | Remove Linux-specific preload and memory-mapping code from the block manager. Get rid of the block-manager calls to posix_fadvise(), support ENOTSUP returns up the stack from the underlying support. General reworking of block preload/discard code to stop attempts whenever ENOTSUP is return on a handle. Remove block manager handle open tests of cache-max and dirty-cache-max configuration conflicts with specifying direct I/O, lacking posix_fadvise and lacking sync_file_range. We can't know in the block manager what the underlying layer can do, and also, the old code was wrong, direct I/O is set on a file type basis, so testing against a specific handle open isn't correct. Inline the block-header-size function, we call it a lot and it's simply returning a size.
