leveldb: Require C++11. This CL switches the public headers to C++11 default and deleted constructors, and adds override to the relevant leveldb::EnvWrapper methods. This should be a good test for C++11 compiler support. Once this CL settles, the rest of the codebase can be safely modernized to C++11. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=189873212

Fix fdatasync() feature detection in opensource build. The CMake feature-detection code used check_symbol_exists(), which invokes the C compiler. However, some glibc versions don't expose the fdatasync() declaration when compiled with -std=c11, but do expose it when compiled with -std=c++11. This most likely comes down to how _POSIX_SOURCE is defined -- it needs to be >= 201112L for <unistd.h> to expose fdatasync(). This CL switches to check_cxx_symbol_exists(), which uses the C++ compiler. Asides from fixing the problem above, this is the right thing to do, because we use <unistd.h> in env_posix.cc, which is compiled with the C++ compiler. This CL also fixes a previously introduced inconsistency, where the macro indicating the fdatasync() feature detection result was referred to as HAVE_FDATASYNC and HAVE_FUNC_FDATASYNC. The former appears to be used in other libraries, so this CL switches all our references to HAVE_FDATASYNC.

leveldb: Fix PosixWritableFile::Sync() on Apple systems. Apple doesn't follow POSIX specifications for fsync(). Instead, fsync() guarantees to flush the buffer cache to the device, which means the data will survive kernel panics, but may not survive power outages. Applications that need stronger guarantees (like databases) need to use fcntl(F_FULLFSYNC). This CL switches PosixWritableFile::Sync() to get the stronger guarantees on Apple systems. The improved implementation follows the same principles as SQLite [1] and node.js [2]. Research for the fcntl() to fsync() fallback strategy: Apple's released source code at https://opensource.apple.com/ shows at least three different error codes being returned when a filesystem does not support F_FULLFSYNC. fcntl() is implemented in xnu-4903.221.2 in bsd/kern/kern_descrip.c, where it delegates to fcntl_nocancel(). The documentation for fcntl_nocancel() mentions error codes for some operations, but does not include F_FULLFSYNC. The F_FULLSYNC branch in fcntl_nocancel() calls VNOP_IOCTL(_, F_FULLSYNC, NULL, 0, _), whose return value sets the error code. VNOP_IOCTL() is implemented in bsd/vfs/kpi_vfs.c and calls the ioctl function in the vnode's operation vector. The per-filesystem function names follow the pattern _vnop_ioctl() for all the instances in opensource code: {hfs,msdosfs,nfs,ntfs,smbfs,webdav,zfs}_vnop_ioctl(). hfs-407.30.1, msdosfs-229.200.3, and nfs in xnu-4903.221.2 handle F_FULLFSYNC. ntfs-94.200.1 and smb-759.40.1 do not handle F_FULLFSYNC, and the default branch returns ENOSUP. webdav-380.200.1 also does not handle F_FULLFSYNC, but the default branch returns EINVAL. zfs-59 also does not handle F_FULLSYNC, and its default branch returns ENOTTY. From a different angle, Apple's ntfs-94.200.1 includes utility code that uses fcntl(F_FULLFSYNC) and falls back to fsync() just like we do, supporting the hypothesis that there is no good way to detect lack of F_FULLFSYNC support. Also, Apple's fcntl() man page [3] does not mention a way to detect lack of F_FULLFSYNC support. [1] https://www.sqlite.org/src/doc/trunk/src/os_unix.c [2] https://github.com/libuv/libuv/blob/master/src/unix/fs.c [3] https://developer.apple.com/library/archive/documentatiVon/System/Conceptual/ManPages_iPhoneOS/man2/fcntl.2.html Tested: https://travis-ci.org/pwnall/leveldb/builds/477318498 TAP global presubmit ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=228593729

Add O_CLOEXEC to open calls. This prevents file descriptors from leaking to child processes. When compiled for older (pre-2.6.23) kernels which lack support for O_CLOEXEC there is no change in behavior. With newer kernels, child processes will no longer inherit leveldb's file handles, which reduces the changes of accidentally corrupting the database.

Define LEVELDB_HAS_PORT_CONFIG_H for old compilers. The CMake-based build relies on __has_include, which is standardized in C++17.

Replace port_posix with port_stdcxx. The porting layer implements threading primitives: atomic pointers, condition variables, mutexes, thread-safe initialization. These are all specified in C++11, so the reference open source port implementation can become platform-independent. The porting layer will remain in place to allow the use of other implementations with more features, such as the built-in deadlock detection in abseil's Mutex. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=193245934

Remove InitOnce from the port API. This is not an API-breaking change, because it reduces the API that the leveldb embedder must implement. The project will build just fine against ports that still implement InitOnce. C++11 guarantees thread-safe initialization of static variables inside functions. This is a more restricted form of std::call_once or pthread_once_t (e.g., single call site), so the compiler might be able to generate better code [1]. Equally important, having less code in port_example.h makes it easier to port to other platforms. Due to the change above, this CL introduces a new approach for storing the singleton BytewiseComparatorImpl instance returned by BytewiseComparator(). The new approach avoids a dynamic memory allocation, which eliminates the false positive from LeakSanitizer reported in https://github.com/google/leveldb/issues/200 [1] https://stackoverflow.com/a/27206650/ ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=212348004
