Histórico

David Grogan 0cfb990d58 Release LevelDB 1.15 - switched from mmap based writing to simpler stdio based writing. Has a minor impact (0.5 microseconds) on microbenchmarks for asynchronous writes. Synchronous writes speed up from 30ms to 10ms on linux/ext4. Should be much more reliable on diverse platforms. - compaction errors now immediately put the database into a read-only mode (until it is re-opened). As a downside, a disk going out of space and then space being created will require a re-open to recover from, whereas previously that would happen automatically. On the plus side, many corruption possibilities go away. - force the DB to enter an error-state so that all future writes fail when a synchronous log write succeeds but the sync fails. - repair now regenerates sstables that exhibit problems - fix issue 218 - Use native memory barriers on OSX - fix issue 212 - QNX build is broken - fix build on iOS with xcode 5 - make tests compile and pass on windows			11 anos atrás

README

This directory contains interfaces and implementations that isolate the
rest of the package from platform details.

Code in the rest of the package includes "port.h" from this directory.
"port.h" in turn includes a platform specific "port_<platform>.h" file
that provides the platform specific implementation.

See port_posix.h for an example of what must be provided in a platform
specific header file.
