From 633caccace3760713631a6b0c5b549fefda640f2 Mon Sep 17 00:00:00 2001 From: Nikhil Benesch Date: Fri, 18 Aug 2017 19:03:55 -0700 Subject: [PATCH 1/5] ensure doctests are not elided by linker opts.set_disable_data_sync was removed from RocksDB (commit eb912a9), but our doctest didn't fail because the function opts.set_disable_data_sync was called in, badly_tuned_for_somebody_elses_disk, was elided by the linker. Remove this function to ensure the doctest actually exercises the code path. --- src/lib.rs | 41 ++++++++++++++++++----------------------- 1 file changed, 18 insertions(+), 23 deletions(-) diff --git a/src/lib.rs b/src/lib.rs index ba26334..fa8d8cd 100644 --- a/src/lib.rs +++ b/src/lib.rs @@ -119,29 +119,24 @@ pub struct BlockBasedOptions { /// use rocksdb::{Options, DB}; /// use rocksdb::DBCompactionStyle; /// -/// fn badly_tuned_for_somebody_elses_disk() -> DB { -/// let path = "path/for/rocksdb/storageX"; -/// let mut opts = Options::default(); -/// opts.create_if_missing(true); -/// opts.set_max_open_files(10000); -/// opts.set_use_fsync(false); -/// opts.set_bytes_per_sync(8388608); -/// opts.set_disable_data_sync(false); -/// opts.optimize_for_point_lookup(1024); -/// opts.set_table_cache_num_shard_bits(6); -/// opts.set_max_write_buffer_number(32); -/// opts.set_write_buffer_size(536870912); -/// opts.set_target_file_size_base(1073741824); -/// opts.set_min_write_buffer_number_to_merge(4); -/// opts.set_level_zero_stop_writes_trigger(2000); -/// opts.set_level_zero_slowdown_writes_trigger(0); -/// opts.set_compaction_style(DBCompactionStyle::Universal); -/// opts.set_max_background_compactions(4); -/// opts.set_max_background_flushes(4); -/// opts.set_disable_auto_compactions(true); -/// -/// DB::open(&opts, path).unwrap() -/// } +/// let mut opts = Options::default(); +/// opts.create_if_missing(true); +/// opts.set_max_open_files(10000); +/// opts.set_use_fsync(false); +/// opts.set_bytes_per_sync(8388608); +/// opts.set_disable_data_sync(false); +/// opts.optimize_for_point_lookup(1024); +/// opts.set_table_cache_num_shard_bits(6); +/// opts.set_max_write_buffer_number(32); +/// opts.set_write_buffer_size(536870912); +/// opts.set_target_file_size_base(1073741824); +/// opts.set_min_write_buffer_number_to_merge(4); +/// opts.set_level_zero_stop_writes_trigger(2000); +/// opts.set_level_zero_slowdown_writes_trigger(0); +/// opts.set_compaction_style(DBCompactionStyle::Universal); +/// opts.set_max_background_compactions(4); +/// opts.set_max_background_flushes(4); +/// opts.set_disable_auto_compactions(true); /// ``` pub struct Options { inner: *mut ffi::rocksdb_options_t, From 9d0a5e28193a617a8c0ace1be7847aa404bfc7e0 Mon Sep 17 00:00:00 2001 From: Nikhil Benesch Date: Fri, 18 Aug 2017 18:30:08 -0700 Subject: [PATCH 2/5] use bindgen to generate ffi Closes #128. --- librocksdb-sys/Cargo.toml | 1 + librocksdb-sys/build.rs | 18 +- librocksdb-sys/src/lib.rs | 1021 +------------------------------------ src/db.rs | 18 +- src/db_options.rs | 12 +- src/lib.rs | 1 - 6 files changed, 34 insertions(+), 1037 deletions(-) diff --git a/librocksdb-sys/Cargo.toml b/librocksdb-sys/Cargo.toml index a47645a..635f905 100644 --- a/librocksdb-sys/Cargo.toml +++ b/librocksdb-sys/Cargo.toml @@ -24,3 +24,4 @@ const-cstr = "0.2" [build-dependencies] gcc = { version = "0.3", features = ["parallel"] } make-cmd = "0.1" +bindgen = "0.29" diff --git a/librocksdb-sys/build.rs b/librocksdb-sys/build.rs index 9b00556..5af57e2 100644 --- a/librocksdb-sys/build.rs +++ b/librocksdb-sys/build.rs @@ -1,6 +1,9 @@ extern crate gcc; +extern crate bindgen; +use std::env; use std::fs; +use std::path::PathBuf; fn link(name: &str, bundled: bool) { use std::env::var; @@ -27,7 +30,18 @@ fn build_rocksdb() { println!("cargo:rerun-if-changed=build.rs"); println!("cargo:rerun-if-changed=rocksdb/"); - let mut config = gcc::Config::new(); + let bindings = bindgen::Builder::default() + .header("rocksdb/include/rocksdb/c.h") + .ctypes_prefix("libc") + .generate() + .expect("unable to generate rocksdb bindings"); + + let out_path = PathBuf::from(env::var("OUT_DIR").unwrap()); + bindings + .write_to_file(out_path.join("bindings.rs")) + .expect("unable to write rocksdb bindings"); + + let mut config = gcc::Build::new(); config.include("rocksdb/include/"); config.include("rocksdb/"); config.include("rocksdb/third-party/gtest-1.7.0/fused-src/"); @@ -108,7 +122,7 @@ fn build_rocksdb() { } fn build_snappy() { - let mut config = gcc::Config::new(); + let mut config = gcc::Build::new(); config.include("snappy/"); config.include("."); diff --git a/librocksdb-sys/src/lib.rs b/librocksdb-sys/src/lib.rs index 8e9b631..192e860 100644 --- a/librocksdb-sys/src/lib.rs +++ b/librocksdb-sys/src/lib.rs @@ -11,1024 +11,11 @@ // WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. // See the License for the specific language governing permissions and // limitations under the License. -// - -//!
