+[![Build Status](https://travis-ci.org/cybozu/libyrmcds.png)](https://travis-ci.org/cybozu/libyrmcds)
+libyrmcds
+=========
+
+libyrmcds is a [memcached][] client library written in C.
+This is a companion to [yrmcds][], a memcached compatible KVS.
+
+In addition to the library itself, a client program called `yc` is included.
+
+Features
+--------
+
+* Minimalistic.
+
+ libyrmcds does *not* provide any rich features like consistent hashing.
+ Instead, it can be used as a base library to implement such rich
+ features.
+
+* Designed for binary protocol.
+
+ In order to access the true power of the binary protocol, libyrmcds
+ is designed primarily for binary protocol. Limited support for the
+ text protocol is provided, though.
+
+* Support for [yrmcds][] extensions.
+
+ Specifically, [the server-side locking][locking] and [the counter extension][counter] is supported.
+
+* Separated send / recv operations.
+
+ Although the socket used in libyrmcds is blocking, receiving results
+ from the server is separated from the sending operations. You can
+ even use a different thread to receive results asynchronously.
+
+* Optional compression with [LZ4][].
+
+ Large objects can be transparently compressed/uncompressed with
+ [LZ4][] compression algorithm.
+
+Build
+-----
+
+Just run `make`.
+
+To support [transparent LZ4 compression][compress], obtain LZ4 source
+code and rebuild the library as follows:
+
+```
+$ make lz4
+$ make clean; make
+```
+
+Install
+-------
+
+Place `yrmcds.h` and `libyrmcds.a` to appropriate directories.
+
+Usage
+-----
+
+See [USAGE.md](USAGE.md).

+Usage
+=====
+
+`yc`
+----
+
+`yc` is a memcached/yrmcds client program. It provides access to all
+libyrmcds library functions therefore access to all server functions.
+
+`yc` prints out its usage when invoked without command-line arguments.
+
+Minimal example
+---------------
+
+```c
+#include <yrmcds.h>
+
+#include <errno.h>
+#include <error.h>
+#include <stdlib.h>
+#include <stdio.h>
+
+void check_error(yrmcds_error e) {
+ if( e != 0 ) {
+ if( e == YRMCDS_SYSTEM_ERROR ) {
+ error(0, errno, "system error");
+ } else {
+ fprintf(stderr, "yrmcds error: %s\n", yrmcds_strerror(e));
+ }
+ exit(2);
+ }
+}
+
+void check_response(const yrmcds_response* r) {
+ if( r->status != YRMCDS_STATUS_OK ) {
+ fprintf(stderr, "Command failed: 0x%04x %.*s\n",
+ r->status, (int)r->data_len, r->data);
+ exit(3);
+ }
+}
+
+int main(int argc, char** argv) {
+ yrmcds c;
+ yrmcds_response r;
+
+ check_error( yrmcds_connect(&c, "localhost", 11211) );
+ check_error( yrmcds_noop(&c, NULL) );
+ check_error( yrmcds_recv(&c, &r) );
+ check_response(&r);
+ check_error( yrmcds_close(&c) );
+
+ return 0;
+}
+```
+
+Compilation and linking
+-----------------------
+
+Link with `-lyrmcds -lpthread` as follows:
+
+```
+gcc -g -O2 -o foo foo.c -lyrmcds -lpthread
+```
+
+Request serial number
+---------------------
+
+All command sending functions can issue a unique serial number of the
+command. This can be used when you receive responses asynchronously
+as described in the next section.
+
+```c
+uint32_t async_cas(yrmcds* c) {
+ uint32_t serial;
+ // try compare-and-swap
+ check_error( yrmcds_set(&c, "abc", 3, "12345", 5, 0, 0, 5, 0, &serial) );
+ return serial;
+}
+```
+
+Multi-threading
+---------------
+
+All functions in libyrmcds are thread-safe as long as different `yrmcds`
+structs are used. Additionally, any number of threads can use command
+sending functions such as `yrmcds_get()` or `yrmcds_set()` even when
+they share the same `yrmcds` struct.
+
+Further, `yrmcds_recv()` can be used in parallel with command sending
+functions. You can create a dedicated thread to receive server responses
+asynchronously. Use request serial numbers to identify a response's
+request.
+
+```c
+void async_recv(yrmcds* c, void (*notify)(uint32_t, yrmcds_response* r)) {
+ yrmcds_respone r;
+ while( 1 ) {
+ check_error( yrmcds_recv(&c, &r) );
+ (*notify)(r.serial, &r);
+ }
+}
+```
+
+You can use `yrmcds_shutdown()` to interrupt the thread blocking in
+`yrmcds_recv()` for graceful exit.
+
+
+Transparent compression
+-----------------------
+
+libyrmcds provides optional transparent data compression by [LZ4][].
+
+To use this feature, the library must be built with LZ4 as follows:
+
+```
+$ make lz4
+$ make
+```
+
+If the library supports LZ4 compression, you can enable transparent
+LZ4 (de)compression for large objects. The threshold for compression
+can be set by `yrmcds_set_compression()`. The compression is disabled
+by default.
+
+Note that all clients must support and enable the compression to
+properly handle compressed data.
+
+Text protocol support
+---------------------
+
+Although libyrmcds is designed for binary protocol, yet it provides
+limited access to text protocol commands. Use `yrmcds_text_mode()`
+to put the connection into the text protocol mode:
+
+```c
+ check_error( yrmcds_connect(&c, "localhost", 11211) );
+ check_error( yrmcds_text_mode(&c) );
+
+ // Use the library API just in the same way as binary protocol.
+```
+
+Limitations:
+
+* Only subset of commands can be used.
+
+ `yrmcds_get_touch`, lock related functions, `yrmcds_incr2` and
+ `yrmcds_decr2`, stat functions, key dump extension are not supported.
+
+* Quiet mutation cannot be used.
+
+ `quiet` arguments must be 0. You need to receive a response for
+ every command.
+
+* `yrmcds_response::cas_unique` is always 0 for storage commands.
+
+ The response for `yrmcds_set`, `yrmcds_add`, or `yrmcds_replace`
+ will not bring the correct CAS value. Use `yrmcds_get` or
+ `yrmcds_getk` to retrieve the correct value.
+
+* `yrmcds_response::command` value is dummy.
+
+ Because `command` is one of binary protocol command numbers.
+
+Counter extension
+-----------------
+
+yrmcds has a distributed counter extension for resource management.
+If the extension is enabled in server, you can access counters by `yrmcds_cnt_*` functions.
+The usage of each function is very similar to the corresponding `yrmcds_` function.
+
+The minimum example is:
+
+```c
+#include <yrmcds.h>
+
+#include <errno.h>
+#include <error.h>
+#include <stdio.h>
+#include <stdlib.h>
+
+void check_error(yrmcds_error e) {
+ if( e != YRMCDS_OK ) {
+ if( e == YRMCDS_SYSTEM_ERROR ) {
+ error(0, errno, "system error");
+ } else {
+ fprintf(stderr, "yrmcds error: %s\n", yrmcds_strerror(e));
+ }
+ exit(2);
+ }
+}
+
+void check_response(const yrmcds_cnt_response* r) {
+ if( r->status != YRMCDS_STATUS_OK ) {
+ fprintf(stderr, "Command failed: 0x%02x %.*s\n",
+ r->status, (int)r->body_length, r->body);
+ exit(3);
+ }
+}
+
+int main(void) {
+ yrmcds_cnt c;
+ yrmcds_cnt_response r;
+
+ check_error( yrmcds_cnt_connect(&c, "localhost", 11215) );
+ check_error( yrmcds_cnt_noop(&c, NULL) );
+ check_error( yrmcds_cnt_recv(&c, &r) );
+ check_response(&r);
+ check_error( yrmcds_cnt_close(&c) );
+
+ return 0;
+}
+```
