It's designed +around the event-driven asynchronous I/O model. + +The library provides much more than simply abstraction over different I/O polling mechanisms: +'handles' and 'streams' provide a high level abstraction for sockets and other entities; +cross-platform file I/O and threading functionality is also provided, amongst other things. + +Here is a diagram illustrating the different parts that compose libuv and what subsystem they +relate to: + +.. image:: static/architecture.png + :scale: 75% + :align: center + + +Handles and requests +^^^^^^^^^^^^^^^^^^^^ + +libuv provides users with 2 abstractions to work with, in combination with the event loop: +handles and requests. + +Handles represent long-lived objects capable of performing certain operations while active. Some +examples: a prepare handle gets its callback called once every loop iteration when active, and +a TCP server handle get its connection callback called every time there is a new connection. + +Requests represent (typically) short-lived operations. These operations can be performed over a +handle: write requests are used to write data on a handle; or standalone: getaddrinfo requests +don't need a handle they run directly on the loop. + + +The I/O loop +^^^^^^^^^^^^ + +The I/O (or event) loop is the central part of libuv. It establishes the content for all I/O +operations, and it's meant to be tied to a single thread. One can run multiple event loops +as long as each runs in a different thread. The libuv event loop (or any other API involving +the loop or handles, for that matter) **is not thread-safe** except where stated otherwise. + +The event loop follows the rather usual single threaded asynchronous I/O approach: all (network) +I/O is performed on non-blocking sockets which are polled using the best mechanism available +on the given platform: epoll on Linux, kqueue on OSX and other BSDs, event ports on SunOS and IOCP +on Windows. As part of a loop iteration the loop will block waiting for I/O activity on sockets +which have been added to the poller and callbacks will be fired indicating socket conditions +(readable, writable hangup) so handles can read, write or perform the desired I/O operation. + +In order to better understand how the event loop operates, the following diagram illustrates all +stages of a loop iteration: + +.. image:: static/loop_iteration.png + :scale: 75% + :align: center + + +#. The loop concept of 'now' is updated. The event loop caches the current time at the start of + the event loop tick in order to reduce the number of time-related system calls. + +#. If the loop is *alive* an iteration is started, otherwise the loop will exit immediately. So, + when is a loop considered to be *alive*? If a loop has active and ref'd handles, active + requests or closing handles it's considered to be *alive*. + +#. Due timers are run. All active timers scheduled for a time before the loop's concept of *now* + get their callbacks called. + +#. Pending callbacks are called. All I/O callbacks are called right after polling for I/O, for the + most part. There are cases, however, in which calling such a callback is deferred for the next + loop iteration. If the previous iteration deferred any I/O callback it will be run at this point. + +#. Idle handle callbacks are called. Despite the unfortunate name, idle handles are run on every + loop iteration, if they are active. + +#. Prepare handle callbacks are called. Prepare handles get their callbacks called right before + the loop will block for I/O. + +#. Poll timeout is calculated. Before blocking for I/O the loop calculates for how long it should + block. These are the rules when calculating the timeout: + + * If the loop was run with the ``UV_RUN_NOWAIT`` flag, the timeout is 0. + * If the loop is going to be stopped (:c:func:`uv_stop` was called), the timeout is 0. + * If there are no active handles or requests, the timeout is 0. + * If there are any idle handles active, the timeout is 0. + * If there are any handles pending to be closed, the timeout is 0. + * If none of the above cases was matched, the timeout of the closest timer is taken, or + if there are no active timers, infinity. + +#. The loop blocks for I/O. At this point the loop will block for I/O for the timeout calculated + on the previous step. All I/O related handles that were monitoring a given file descriptor + for a read or write operation get their callbacks called at this point. + +#. Check handle callbacks are called. Check handles get their callbacks called right after the + loop has blocked for I/O. Check handles are essentially the counterpart of prepare handles. + +#. Close callbacks are called. If a handle was closed by calling :c:func:`uv_close` it will + get the close callback called. + +#. Special case in case the loop was run with ``UV_RUN_ONCE``, as it implies forward progress. + It's possible that no I/O callbacks were fired after blocking for I/O, but some time has passed + so there might be timers which are due, those timers get their callbacks called. + +#. Iteration ends. If the loop was run with ``UV_RUN_NOWAIT`` or ``UV_RUN_ONCE`` modes the + iteration is ended and :c:func:`uv_run` will return.

This is done repeatedly until all idle watchers are inactive. + * - If a watcher starts another watcher of the same type its callback is not + * immediately queued. For check and prepare watchers, that means that if + * a watcher makes another of the same type active, it'll not be called until + * the next event loop iteration. For idle. watchers this means that the + * newly activated idle watcher might not be queued immediately. + * - Prepare, check, idle watchers keep the event loop alive even when they're + * not active. + * + * This is what the test globally does: + * + * - prepare_1 is always active and counts event loop iterations. It also + * creates and starts prepare_2 every other iteration. Finally it verifies + * that no idle watchers are active before polling. + * - prepare_2 is started by prepare_1 every other iteration. It immediately + * stops itself. It verifies that a watcher is not queued immediately + * if created by another watcher of the same type. + * - There's a check watcher that stops the event loop after a certain number + * of iterations. It starts a varying number of idle_1 watchers. + * - Idle_1 watchers stop themselves after being called a few times. All idle_1 + * watchers try to start the idle_2 watcher if it is not already started or + * awaiting its close callback. + * - The idle_2 watcher always exists but immediately closes itself after + * being started by a check_1 watcher. It verifies that a watcher is + * implicitly stopped when closed, and that a watcher can close itself + * safely. + * - There is a repeating timer.

LuaFileSystem
+
File System Library for the Lua Programming Language
+
+ +
+ + + +
+ +

Introduction

+ +

LuaFileSystem is a Lua library +developed to complement the set of functions related to file +systems offered by the standard Lua distribution.

+ +

LuaFileSystem offers a portable way to access +the underlying directory structure and file attributes.

+ +

Building

+ +

+LuaFileSystem should be built with Lua 5.1 so the language library +and header files for the target version must be installed properly. +

+ +

+LuaFileSystem offers a Makefile and a separate configuration file, +config, +which should be edited to suit your installation before running +make. +The file has some definitions like paths to the external libraries, +compiler options and the like. +

+ +

On Windows, the C runtime used to compile LuaFileSystem must be the same +runtime that Lua uses, or some LuaFileSystem functions will not work.

+ +

Installation

+ +

The easiest way to install LuaFileSystem is to use LuaRocks:

+ +
+luarocks install luafilesystem
+
+ +

If you prefer to install LuaFileSystem manually, the compiled binary should be copied to a directory in your +C path.

+ +

Reference

+ +

+LuaFileSystem offers the following functions: +

+ +
+
lfs.attributes (filepath [, aname])
+
Returns a table with the file attributes corresponding to + filepath (or nil followed by an error message + in case of error). + If the second optional argument is given, then only the value of the + named attribute is returned (this use is equivalent to + lfs.attributes(filepath).aname, but the table is not created + and only one attribute is retrieved from the O.S.). + The attributes are described as follows; + attribute mode is a string, all the others are numbers, + and the time related attributes use the same time reference of + os.time: +
+
dev
+
on Unix systems, this represents the device that the inode resides on. On Windows systems, + represents the drive number of the disk containing the file
+ +
ino
+
on Unix systems, this represents the inode number. On Windows systems this has no meaning
+ +
mode
+
string representing the associated protection mode (the values could be + file, directory, link, socket, + named pipe, char device, block device or + other)
+ +
nlink
+
number of hard links to the file
+ +
uid
+
user-id of owner (Unix only, always 0 on Windows)
+ +
gid
+
group-id of owner (Unix only, always 0 on Windows)
+ +
rdev
+
on Unix systems, represents the device type, for special file inodes. + On Windows systems represents the same as dev
+ +
access
+
time of last access
+ +
modification
+
time of last data modification
+ +
change
+
time of last file status change
+ +
size
+
file size, in bytes
+ +
blocks
+
block allocated for file; (Unix only)
+ +
blksize
+
optimal file system I/O blocksize; (Unix only)
+
+ This function uses stat internally thus if the given + filepath is a symbolic link, it is followed (if it points to + another link the chain is followed recursively) and the information + is about the file it refers to. + To obtain information about the link itself, see function + lfs.symlinkattributes. +
+ +
lfs.chdir (path)
+
Changes the current working directory to the given + path.
+ Returns true in case of success or nil plus an + error string.
+ +
lfs.lock_dir(path, [seconds_stale])
+
Creates a lockfile (called lockfile.lfs) in path if it does not + exist and returns the lock. If the lock already exists checks if + it's stale, using the second parameter (default for the second + parameter is INT_MAX, which in practice means the lock will never + be stale. To free the the lock call lock:free().
+ In case of any errors it returns nil and the error message. In + particular, if the lock exists and is not stale it returns the + "File exists" message.
+ +
lfs.currentdir ()
+
Returns a string with the current working directory or nil + plus an error string.
+ +
iter, dir_obj = lfs.dir (path)
+
+ Lua iterator over the entries of a given directory. + Each time the iterator is called with dir_obj it returns a directory entry's name as a string, or + nil if there are no more entries. You can also iterate by calling dir_obj:next(), and + explicitly close the directory before the iteration finished with dir_obj:close(). + Raises an error if path is not a directory. +
+ +
lfs.lock (filehandle, mode[, start[, length]])
+
Locks a file or a part of it. This function works on open files; the + file handle should be specified as the first argument. + The string mode could be either + r (for a read/shared lock) or w (for a + write/exclusive lock). The optional arguments start + and length can be used to specify a starting point and + its length; both should be numbers.
+ Returns true if the operation was successful; in + case of error, it returns nil plus an error string. +
+ +
lfs.link (old, new[, symlink])
+
Creates a link. The first argument is the object to link to + and the second is the name of the link. If the optional third + argument is true, the link will by a symbolic link (by default, a + hard link is created). +
+ +
lfs.mkdir (dirname)
+
Creates a new directory. The argument is the name of the new + directory.
+ Returns true if the operation was successful; + in case of error, it returns nil plus an error string. +
+ +
lfs.rmdir (dirname)
+
Removes an existing directory. The argument is the name of the directory.
+ Returns true if the operation was successful; + in case of error, it returns nil plus an error string.
+ +
lfs.setmode (file, mode)
+
Sets the writing mode for a file. The mode string can be either "binary" or "text". + Returns true followed the previous mode string for the file, or + nil followed by an error string in case of errors. + On non-Windows platforms, where the two modes are identical, + setting the mode has no effect, and the mode is always returned as binary. +
+ +
lfs.symlinkattributes (filepath [, aname])
+
Identical to lfs.attributes except that + it obtains information about the link itself (not the file it refers to). + On Windows this function does not yet support links, and is identical to + lfs.attributes. +
+ +
lfs.touch (filepath [, atime [, mtime]])
+
Set access and modification times of a file. This function is + a bind to utime function. The first argument is the + filename, the second argument (atime) is the access time, + and the third argument (mtime) is the modification time. + Both times are provided in seconds (which should be generated with + Lua standard function os.time). + If the modification time is omitted, the access time provided is used; + if both times are omitted, the current time is used.
+ Returns true if the operation was successful; + in case of error, it returns nil plus an error string. +
+ +
lfs.unlock (filehandle[, start[, length]])
+
Unlocks a file or a part of it. This function works on + open files; the file handle should be specified as the first + argument. The optional arguments start and + length can be used to specify a starting point and its + length; both should be numbers.
+ Returns true if the operation was successful; + in case of error, it returns nil plus an error string. +

On Ubuntu, the `build-essential` +package is good for this. + +On OSX, you probably want XCode which comes with `clang` and `make` and friends. + +For windows the free Visual Studio Express works. If you get the 2013 edition, +make sure to get the `Windows Deskop` edition. The `Windows` version doesn't +include a working C compiler. Make sure to run all of setup including getting a +free license. + +### Install CMake + +Now install Cmake. The version in `brew` on OSX or most Linux package managers +is good. The version on Travis CI is too old and so I use a PPA there. On +windows use the installer and make sure to add cmake to your command prompt +path. + +### Install Git + +If you haven't already, install git and make sure it's in your path. This comes +with XCode on OSX. On Linux it's in your package manager. For windows, use the +installer at . Make sure it's available to your windows +command prompt. + +### Clone the Code + +Now open a terminal and clone the code. For windows I recommend the special +developer command prompt that came with Visual Studio. + +``` +git clone https://github.com/luvit/luv.git --recursive +cd luv +``` + +### Build the Code and Test + +On windows I wrote a small batch file that runs the correct cmake commands and +copies the output files for easy access. + +``` +C:\Code\luv> msvcbuild.bat +C:\Code\luv> luajit tests\run.lua +``` + +On unix systems, use the Makefile. + +``` +~/Code/luv> make test +``` + +This will build luv as a module library. Module libraries are plugins that are +not linked into other targets. + +#### Build with PUC Lua 5.3 +By default luv is linked with LuaJIT 2.0.4.

-0,0 +1,1309 @@ +# LibUV in Lua + +The [luv][] project provides access to the multi-platform support library +[libuv][] to lua code. It was primariliy developed for the [luvit][] project as +the `uv` builtin module, but can be used in other lua environments. + +### TCP Echo Server Example + +Here is a small example showing a TCP echo server: + +```lua +local uv = require('uv') + +local server = uv.new_tcp() +server:bind("127.0.0.1", 1337) +server:listen(128, function (err) + assert(not err, err) + local client = uv.new_tcp() + server:accept(client) + client:read_start(function (err, chunk) + assert(not err, err) + if chunk then + client:write(chunk) + else + client:shutdown() + client:close() + end + end) +end) +print("TCP server listening at 127.0.0.1 port 1337") +uv.run() +``` + +### Methods vs Functions + +As a quick note, [libuv][] is a C library and as such, there are no such things +as methods. The [luv][] bindings allow calling the libuv functions as either +functions or methods. For example, calling `server:bind(host, port)` is +equivalent to calling `uv.tcp_bind(server, host, port)`. All wrapped uv types +in lua have method shortcuts where is makes sense. Some are even renamed +shorter like the `tcp_` prefix that removed in method form. Under the hood it's +the exact same C function. + +## Table Of Contents + +The rest of the docs are organized by libuv type. There is some hierarchy as +most types are considered handles and some are considered streams. + + - [`uv_loop_t`][] — Event loop + - [`uv_handle_t`][] — Base handle + - [`uv_timer_t`][] — Timer handle + - [`uv_prepare_t`][] — Prepare handle + - [`uv_check_t`][] — Check handle + - [`uv_idle_t`][] — Idle handle + - [`uv_async_t`][] — Async handle + - [`uv_poll_t`][] — Poll handle + - [`uv_signal_t`][] — Signal handle + - [`uv_process_t`][] — Process handle + - [`uv_stream_t`][] — Stream handle + - [`uv_tcp_t`][] — TCP handle + - [`uv_pipe_t`][] — Pipe handle + - [`uv_tty_t`][] — TTY handle + - [`uv_udp_t`][] — UDP handle + - [`uv_fs_event_t`][] — FS Event handle + - [`uv_fs_poll_t`][] — FS Poll handle + - [Filesystem operations][] + - [DNS utility functions][] + - [Miscellaneous utilities][] + +## `uv_loop_t` — Event loop + +[`uv_loop_t`]: #uv_loop_t--event-loop + +The event loop is the central part of libuv’s functionality. It takes care of +polling for i/o and scheduling callbacks to be run based on different sources of +events. + +In [luv][], there is an implicit uv loop for every lua state that loads the +library. You can use this library in an multithreaded environment as long as +each thread has it's own lua state with corresponsding own uv loop. + +### `uv.loop_close()` + +Closes all internal loop resources. This function must only be called once the +loop has finished its execution or it will raise a UV_EBUSY error. + +### `uv.run([mode])` + +> optional `mode` defaults to `"default"` + +This function runs the event loop. It will act differently depending on the +specified mode: + + - `"default"`: Runs the event loop until there are no more active and + referenced handles or requests. Always returns `false`. + + - `"once"`: Poll for i/o once. Note that this function blocks if there are no + pending callbacks. Returns `false` when done (no active handles or requests + left), or `true` if more callbacks are expected (meaning you should run + the event loop again sometime in the future). + + - `"nowait"`: Poll for i/o once but don’t block if there are no + pending callbacks. Returns `false` if done (no active handles or requests + left), or `true` if more callbacks are expected (meaning you should run + the event loop again sometime in the future). + +Luvit will implicitly call `uv.run()` after loading user code, but if you use +the `luv` bindings directly, you need to call this after registering your +initial set of event callbacks to start the event loop. + +### `uv.loop_alive()` + +Returns true if there are active handles or request in the loop. + +### `uv.stop()` + +Stop the event loop, causing `uv_run()` to end as soon as possible. This +will happen not sooner than the next loop iteration. If this function was called +before blocking for i/o, the loop won’t block for i/o on this iteration. + +### `uv.backend_fd()` + +Get backend file descriptor. Only kqueue, epoll and event ports are supported. + +This can be used in conjunction with `uv_run("nowait")` to poll in one thread +and run the event loop’s callbacks in another. + +**Note**: Embedding a kqueue fd in another kqueue pollset doesn’t work on all +platforms. It’s not an error to add the fd but it never generates events. + +### `uv.backend_timeout()` + +Get the poll timeout. The return value is in milliseconds, or -1 for no timeout. + +### `uv.now()` + +Return the current timestamp in milliseconds.

Using `uv_poll_t` for any other purpose is not recommended; +`uv_tcp_t`, `uv_udp_t`, etc. provide an implementation that is faster and more +scalable than what can be achieved with `uv_poll_t`, especially on Windows. + +It is possible that poll handles occasionally signal that a file descriptor is +readable or writable even when it isn’t. The user should therefore always be +prepared to handle EAGAIN or equivalent when it attempts to read from or write +to the fd. + +It is not okay to have multiple active poll handles for the same socket, this +can cause libuv to busyloop or otherwise malfunction. + +The user should not close a file descriptor while it is being polled by an +active poll handle. This can cause the handle to report an error, but it might +also start polling another socket. However the fd can be safely closed +immediately after a call to `uv.poll_stop()` or `uv.close()`. + +**Note** On windows only sockets can be polled with poll handles. On Unix any +file descriptor that would be accepted by poll(2) can be used. + + +### `uv.new_poll(fd) -> poll` + +Initialize the handle using a file descriptor. + +The file descriptor is set to non-blocking mode. + +### `uv.new_socket_poll(fd) -> poll` + +Initialize the handle using a socket descriptor.

On windows it takes a SOCKET handle. + +The socket is set to non-blocking mode. + +### `uv.poll_start(poll, events, callback)` + +> method form `poll:start()` + +Starts polling the file descriptor. `events` is `"r"`, `"w"`, or `"rw"` and +translates to a bitmask made up of UV_READABLE and UV_WRITABLE. As soon as an +event is detected the callback will be called with status set to 0, and the +detected events set on the events field. + +The user should not close the socket while the handle is active. If the user +does that anyway, the callback may be called reporting an error status, but this +is not guaranteed. + +**Note** Calling `uv.poll_start()`` on a handle that is already active is fine. +Doing so will update the events mask that is being watched for. + +## `uv.poll_stop(poll)` + +> method form `poll:stop()` + +Stop polling the file descriptor, the callback will no longer be called. + +## `uv_signal_t` — Signal handle + +[`uv_signal_t`]: #uv_signal_t--signal-handle + +Signal handles implement Unix style signal handling on a per-event loop bases. + +Reception of some signals is emulated on Windows: +* SIGINT is normally delivered when the user presses CTRL+C. However, like on +Unix, it is not generated when terminal raw mode is enabled. +* SIGBREAK is delivered when the user pressed CTRL + BREAK. +* SIGHUP is generated when the user closes the console window. On SIGHUP the +program is given approximately 10 seconds to perform cleanup. After that +Windows will unconditionally terminate it. +* SIGWINCH is raised whenever libuv detects that the console has been resized. +SIGWINCH is emulated by libuv when the program uses a uv_tty_t handle to write +to the console. SIGWINCH may not always be delivered in a timely manner; libuv +will only detect size changes when the cursor is being moved. When a readable +[`uv_tty_t`][] handle is used in raw mode, resizing the console buffer will +also trigger a SIGWINCH signal. + +Watchers for other signals can be successfully created, but these signals are +never received. These signals are: SIGILL, SIGABRT, SIGFPE, SIGSEGV, SIGTERM +and SIGKILL. + +Calls to raise() or abort() to programmatically raise a signal are not detected +by libuv; these will not trigger a signal watcher. + +**Note**: On Linux SIGRT0 and SIGRT1 (signals 32 and 33) are used by the NPTL +pthreads library to manage threads.
