Note that CivetWeb makes internal copies of + passed options. +- SSL context, if any +- user-defined callbacks +- opened listening sockets +- a queue for accepted sockets +- mutexes and condition variables for inter-thread synchronization + +When `mg_start()` returns, all initialization is guaranteed to be complete +(e.g. listening ports are opened, SSL is initialized, etc). `mg_start()` starts +some threads: a master thread, that accepts new connections, and several +worker threads, that process accepted connections. The number of worker threads +is configurable via `num_threads` configuration option. That number puts a +limit on number of simultaneous requests that can be handled by CivetWeb. +If you embed CivetWeb into a program that uses SSL outside CivetWeb as well, +you may need to initialize SSL before calling `mg_start()`, and set the pre- +processor define `SSL_ALREADY_INITIALIZED`. This is not required if SSL is +used only within CivetWeb. + +When master thread accepts new a connection, a new accepted socket (described +by `struct socket`) it placed into the accepted sockets queue, +which has size of `MGSQLEN` (default 20). +Any idle worker thread can grab accepted sockets from that queue. +If all worker threads are busy, master thread can accept and queue up to +20 more TCP connections, filling up the queue. +In the attempt to queue even more accepted connection, the master thread blocks +until there is space in the queue. When the master thread is blocked on a +full queue, the operating system can also queue incoming connection. +The number is limited by the `listen()` call parameter, +which is `SOMAXCONN` and depends on the platform. + +Worker threads are running in an infinite loop, which in a simplified form +looks something like this: + +```C + static void *worker_thread() { + while (consume_socket()) { + process_new_connection(); + } + } +``` + +Function `consume_socket()` gets a new accepted socket from the CivetWeb socket +queue, atomically removing it from the queue. If the queue is empty, +`consume_socket()` blocks and waits until a new socket is placed in the queue +by the master thread. + +`process_new_connection()` actually processes the +connection, i.e. reads the request, parses it, and performs appropriate action +depending on the parsed request. + +Master thread uses `poll()` and `accept()` to accept new connections on +listening sockets. `poll()` is used to avoid `FD_SETSIZE` limitation of +`select()`. Since there are only a few listening sockets, there is no reason +to use hi-performance alternatives like `epoll()` or `kqueue()`. Worker +threads use blocking IO on accepted sockets for reading and writing data. +All accepted sockets have `SO_RCVTIMEO` and `SO_SNDTIMEO` socket options set +(controlled by the `request_timeout_ms` CivetWeb option, 30 seconds default) +which specifies a read/write timeout on client connections. + + +A minimal example +------ + +Initializing a HTTP server +```C +{ + /* Server context handle */ + struct mg_context *ctx; + + /* Initialize the library */ + mg_init_library(0); + + /* Start the server */ + ctx = mg_start(NULL, 0, NULL); + + /* Add some handler */ + mg_set_request_handler(ctx, "/hello", handler, "Hello world"); + + ...

See `Embedding.md` for information on embedding civetweb into +host applications. + +The stand-alone server is self-contained, and does not require any external +software to run. Some Windows users may need to install the +[Visual C++ Redistributable](http://www.microsoft.com/en-us/download/details.aspx?id=30679). + +Installation +---- + +On Windows, UNIX and Mac, the civetweb stand-alone executable may be started +from the command line. +Running `civetweb` in a terminal, optionally followed by configuration parameters +(`civetweb [OPTIONS]`) or a configuration file name (`civetweb [config_file_name]`), +starts the web server. + +For UNIX and Mac, civetweb does not detach from the terminal. +Pressing `Ctrl-C` keys will stop the server. + +On Windows, civetweb iconifies itself to the system tray icon when started. +Right-click on the icon pops up a menu, where it is possible to stop +civetweb, or configure it, or install it as Windows service. + +When started without options, the server exposes the local directory at +[http](http://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol) port 8080. +Thus, the easiest way to share a folder on Windows is to copy `civetweb.exe` +to this folder, double-click the exe, and launch a browser at +[http://localhost:8080](http://localhost:8080). Note that 'localhost' should +be changed to a machine's name if a folder is accessed from other computer. + +When started, civetweb first searches for the configuration file. +If configuration file is specified explicitly in the command line, i.e. +`civetweb path_to_config_file`, then specified configuration file is used. +Otherwise, civetweb would search for file `civetweb.conf` in the same directory +the executable is located, and use it. This configuration file is optional. + +The configuration file is a sequence of lines, each line containing one +command line argument name and the corresponding value. +Empty lines, and lines beginning with `#`, are ignored. +Here is the example of `civetweb.conf` file: + + document_root c:\www + listening_ports 80,443s + ssl_certificate c:\civetweb\ssl_cert.pem + +When a configuration file is used, additional command line arguments may +override the configuration file settings. +All command line arguments must start with `-`. + +For example: The above `civetweb.conf` file is used, and civetweb started as +`civetweb -document_root D:\web`. Then the `D:\web` directory will be served +as document root, because command line options take priority over the +configuration file. The configuration options section below provides a good +overview of the Civetweb features. + +Note that configuration options on the command line must start with `-`, +but their names are the same as in the config file. All option names are +listed in the next section. Thus, the following two setups are equivalent: + + # Using command line arguments + $ civetweb -listening_ports 1234 -document_root /var/www + + # Using config file + $ cat civetweb.conf + listening_ports 1234 + document_root /var/www + $ civetweb + +Civetweb can also be used to modify `.htpasswd` passwords files: + + civetweb -A + +Unlike other web servers, civetweb does not require CGI scripts to be located +in a special directory. CGI scripts can be anywhere. CGI (and SSI) files are +recognized by the file name pattern. Civetweb uses shell-like glob +patterns. Pattern match starts at the beginning of the string, so essentially +patterns are prefix patterns. Syntax is as follows: + + ** Matches everything + * Matches everything but slash character, '/' + ? Matches any character + $ Matches the end of the string + | Matches if pattern on the left side or the right side matches. + +All other characters in the pattern match themselves. Examples: + + **.cgi$ Any string that ends with .cgi + /foo Any string that begins with /foo + **a$|**b$ Any string that ends with a or b + +# Configuration Options + +Below is a list of configuration options understood by Civetweb. +Every option is followed by it's default value. If a default value is not +present, then the default is empty. + +### cgi\_pattern `**.cgi$|**.pl$|**.php$` +All files that match `cgi_pattern` are treated as CGI files. Default pattern +allows CGI files be anywhere. To restrict CGIs to a certain directory, +use `/path/to/cgi-bin/**.cgi` as pattern. Note that the full file path is +matched against the pattern, not the URI. + +### cgi\_environment +Extra environment variables to be passed to the CGI script in +addition to standard ones. The list must be comma-separated list +of name=value pairs, like this: `VARIABLE1=VALUE1,VARIABLE2=VALUE2`. + +### put\_delete\_auth\_file +Passwords file for PUT and DELETE requests. Without password file, it will not +be possible to, PUT new files to the server or DELETE existing ones. PUT and +DELETE requests might still be handled by Lua scripts and CGI paged. + +### cgi\_interpreter +Path to an executable to use as CGI interpreter for __all__ CGI scripts +regardless of the script file extension. If this option is not set (which is +the default), Civetweb looks at first line of a CGI script, +[shebang line](http://en.wikipedia.org/wiki/Shebang_(Unix\)), for an +interpreter (not only on Linux and Mac but also for Windows). + +For example, if both PHP and Perl CGIs are used, then +`#!/path/to/php-cgi.exe` and `#!/path/to/perl.exe` must be first lines of the +respective CGI scripts. Note that paths should be either full file paths, +or file paths relative to the current working directory of the civetweb +server. If civetweb is started by mouse double-click on Windows, the current +working directory is the directory where the civetweb executable is located. + +If all CGIs use the same interpreter, for example they are all PHP, it is +more efficient to set `cgi_interpreter` to the path to `php-cgi.exe`. +The shebang line in the CGI scripts can be omitted in this case. +Note that PHP scripts must use `php-cgi.exe` as executable, not `php.exe`. + +### protect\_uri +Comma separated list of URI=PATH pairs, specifying that given +URIs must be protected with password files specified by PATH. +All Paths must be full file paths. + +### authentication\_domain `mydomain.com` +Authorization realm used for HTTP digest authentication. This domain is +used in the encoding of the `.htpasswd` authorization files as well. +Changing the domain retroactively will render the existing passwords useless. + +### enable\_auth\_domain\_check `yes` +When using absolute URLs, verify the host is identical to the authentication\_domain. If enabled, requests to absolute URLs will only be processed +if they are directed to the domain. If disabled, absolute URLs to any host +will be accepted. + +### ssi\_pattern `**.shtml$|**.shtm$` +All files that match `ssi_pattern` are treated as Server Side Includes (SSI). + +SSI is a simple interpreted server-side scripting language which is most +commonly used to include the contents of another file into a web page. +It can be useful when it is desirable to include a common piece +of code throughout a website, for example, headers and footers. + +In order for a webpage to recognize an SSI-enabled HTML file, the filename +should end with a special extension, by default the extension should be +either `.shtml` or `.shtm`. These extentions may be changed using the +`ssi_pattern` option. + +Unknown SSI directives are silently ignored by civetweb. Currently, two SSI +directives are supported, ` + +For more information on Server Side Includes, take a look at the Wikipedia: +[Server Side Includes](http://en.wikipedia.org/wiki/Server_Side_Includes) + +### throttle +Limit download speed for clients. `throttle` is a comma-separated +list of key=value pairs, where key could be: + + * limit speed for all connections + x.x.x.x/mask limit speed for specified subnet + uri_prefix_pattern limit speed for given URIs + +The value is a floating-point number of bytes per second, optionally +followed by a `k` or `m` character, meaning kilobytes and +megabytes respectively. A limit of 0 means unlimited rate. The +last matching rule wins. Examples: + + *=1k,10.0.0.0/8=0 limit all accesses to 1 kilobyte per second, + but give connections the from 10.0.0.0/8 subnet + unlimited speed + + /downloads/=5k limit accesses to all URIs in `/downloads/` to + 5 kilobytes per second. All other accesses are unlimited + +### access\_log\_file +Path to a file for access logs. Either full path, or relative to the current +working directory. If absent (default), then accesses are not logged. + +### enable\_directory\_listing `yes` +Enable directory listing, either `yes` or `no`. + +### error\_log\_file +Path to a file for error logs. Either full path, or relative to the current +working directory. If absent (default), then errors are not logged. + +### global\_auth\_file +Path to a global passwords file, either full path or relative to the current +working directory. If set, per-directory `.htpasswd` files are ignored, +and all requests are authorized against that file. + +The file has to include the realm set through `authentication_domain` and the +password in digest format: + + user:realm:digest + test:test.com:ce0220efc2dd2fad6185e1f1af5a4327 + +Password files may be generated using `civetweb -A` as explained above, or +online tools e.g. [this generator](http://www.askapache.com/online-tools/htpasswd-generator). + +### index\_files `index.xhtml,index.html,index.htm,index.cgi,index.shtml,index.php` +Comma-separated list of files to be treated as directory index files. +If more than one matching file is present in a directory, the one listed to the left +is used as a directory index. + +In case built-in Lua support has been enabled, `index.lp,index.lsp,index.lua` +are additional default index files, ordered before `index.cgi`. + +### enable\_keep\_alive `no` +Enable connection keep alive, either `yes` or `no`. + +Allows clients to reuse TCP connection for subsequent HTTP requests, +which improves performance. +For this to work when using request handlers it is important to add the +correct Content-Length HTTP header for each request. If this is forgotten the +client will time out. + +Note: If you set keep\_alive to `yes`, you should set keep\_alive\_timeout\_ms +to some value > 0 (e.g. 500). If you set keep\_alive to `no`, you should set +keep\_alive\_timeout\_ms to 0. Currently, this is done as a default value, +but this configuration is redundant. In a future version, the keep\_alive +configuration option might be removed and automatically set to `yes` if +a timeout > 0 is set. + +### access\_control\_list +An Access Control List (ACL) allows restrictions to be put on the list of IP +addresses which have access to the web server. In the case of the Civetweb +web server, the ACL is a comma separated list of IP subnets, where each +subnet is pre-pended by either a `-` or a `+` sign. A plus sign means allow, +where a minus sign means deny. If a subnet mask is omitted, such as `-1.2.3.4`, +this means to deny only that single IP address. + +Subnet masks may vary from 0 to 32, inclusive. The default setting is to allow +all accesses. On each request the full list is traversed, and +the last match wins. Examples: + + -0.0.0.0/0,+192.168/16 deny all accesses, only allow 192.168/16 subnet + +To learn more about subnet masks, see the +[Wikipedia page on Subnetwork](http://en.wikipedia.org/wiki/Subnetwork). + +### extra\_mime\_types +Extra mime types, in tha form `extension1=type1,exten-sion2=type2,...`. +See the [Wikipedia page on Internet media types](http://en.wikipedia.org/wiki/Internet_media_type). +Extension must include a leading dot. Example: +`.cpp=plain/text,.java=plain/text` + +### listening\_ports `8080` +Comma-separated list of ports to listen on. If the port is SSL, a +letter `s` must be appended, for example, `80,443s` will open +port 80 and port 443, and connections on port 443 will be SSL-ed. +For non-SSL ports, it is allowed to append letter `r`, meaning 'redirect'. +Redirect ports will redirect all their traffic to the first configured +SSL port. For example, if `listening_ports` is `80r,443s`, then all +HTTP traffic coming at port 80 will be redirected to HTTPS port 443. + +It is possible to specify an IP address to bind to. In this case, +an IP address and a colon must be pre-pended to the port number. +For example, to bind to a loopback interface on port 80 and to +all interfaces on HTTPS port 443, use `127.0.0.1:80,443s`. + +If the server is built with IPv6 support, `[::]:8080` can be used to +listen to IPv6 connections to port 8080. IPv6 addresses of network +interfaces can be specified as well, +e.g. `[::1]:8080` for the IPv6 loopback interface. + +[::]:80 will bind to port 80 IPv6 only. In order to use port 80 for +all interfaces, both IPv4 and IPv6, use either the configuration +`80,[::]:80` (create one socket for IPv4 and one for IPv6 only), +or `+80` (create one socket for both, IPv4 and IPv6). +The `+`-notation to use IPv4 and IPv6 will only work in no network +interface is specified. Depending on your operating system version +and IPv6 network environment, some configurations might not work +as expected, so you have to test to find the configuration most +suitable for your needs. In case `+80` does not work for your +environment, you need to use `80,[::]:80`. + +It is possible to use network interface addresses (e.g., `192.0.2.3:80`, +`[2001:0db8::1234]:80`). To get a list of available network interface +addresses, use `ipconfig` (in a `cmd` window in Windows) or `ifconfig` +(in a Linux shell). +Alternatively, you could use the hostname for an interface. Check the +hosts file of your operating system for a proper hostname +(for Windows, usually found in C:\Windows\System32\drivers\etc\, +for most Linux distributions: /etc/hosts). E.g., to bind the IPv6 +local host, you could use `ip6-localhost:80`. This translates to +`[::1]:80`. Beside the hosts file, there are several other name +resolution services. Using your hostname might bind you to the +localhost or an external interface. You could also try `hostname.local`, +if the proper network services are installed (Zeroconf, mDNS, Bonjour, +Avahi). When using a hostname, you need to test in your particular network +environment - in some cases, you might need to resort to a fixed IP address. + +### document\_root `.` +A directory to serve. By default, the current working directory is served. +The current directory is commonly referenced as dot (`.`). +It is recommended to use an absolute path for document\_root, in order to +avoid accidentally serving the wrong directory. + +### ssl\_certificate +Path to the SSL certificate file. This option is only required when at least +one of the `listening\_ports` is SSL. The file must be in PEM format, +and it must have both, private key and certificate, see for example +[ssl_cert.pem](https://github.com/civetweb/civetweb/blob/master/resources/ssl_cert.pem) +A description how to create a certificate can be found in doc/OpenSSL.md + +### num\_threads `50` +Number of worker threads. Civetweb handles each incoming connection in a +separate thread. Therefore, the value of this option is effectively the number +of concurrent HTTP connections Civetweb can handle. + +### run\_as\_user +Switch to given user credentials after startup. Usually, this option is +required when civetweb needs to bind on privileged ports on UNIX. To do +that, civetweb needs to be started as root. From a security point of view, +running as root is not advisable, therefore this option can be used to drop +privileges. Example: + + civetweb -listening_ports 80 -run_as_user webserver + +### url\_rewrite\_patterns +Comma-separated list of URL rewrites in the form of +`uri_pattern=file_or_directory_path`. When Civetweb receives any request, +it constructs the file name to show by combining `document_root` and the URI. +However, if the rewrite option is used and `uri_pattern` matches the +requested URI, then `document_root` is ignored. Instead, +`file_or_directory_path` is used, which should be a full path name or +a path relative to the web server's current working directory. Note that +`uri_pattern`, as all civetweb patterns, is a prefix pattern. + +This makes it possible to serve many directories outside from `document_root`, +redirect all requests to scripts, and do other tricky things. For example, +to redirect all accesses to `.doc` files to a special script, do: + + civetweb -url_rewrite_patterns **.doc$=/path/to/cgi-bin/handle_doc.cgi + +Or, to imitate support for user home directories, do: + + civetweb -url_rewrite_patterns /~joe/=/home/joe/,/~bill=/home/bill/ + +### hide\_files\_patterns +A pattern for the files to hide. Files that match the pattern will not +show up in directory listing and return `404 Not Found` if requested. Pattern +must be for a file name only, not including directory names. Example: + + civetweb -hide_files_patterns secret.txt|**.hide + +Note: hide\_file\_patterns uses the pattern described above. If you want to +hide all files with a certain extension, make sure to use **.extension +(not just *.extension). + +### request\_timeout\_ms `30000` +Timeout for network read and network write operations, in milliseconds. +If a client intends to keep long-running connection, either increase this +value or (better) use keep-alive messages. + +### keep\_alive\_timeout\_ms `500` or `0` +Idle timeout between two requests in one keep-alive connection. +If keep alive is enabled, multiple requests using the same connection +are possible. This reduces the overhead for opening and closing connections +when loading several resources from one server, but it also blocks one port +and one thread at the server during the lifetime of this connection. +Unfortunately, browsers do not close the keep-alive connection after loading +all resources required to show a website. +The server closes a keep-alive connection, if there is no additional request +from the client during this timeout. + +Note: if enable\_keep\_alive is set to `no` the value of +keep\_alive\_timeout\_ms should be set to `0`, if enable\_keep\_alive is set +to `yes`, the value of keep\_alive\_timeout\_ms must be >0. +Currently keep\_alive\_timeout\_ms is ignored if enable\_keep\_alive is no, +but future versions my drop the enable\_keep\_alive configuration value and +automatically use keep-alive if keep\_alive\_timeout\_ms is not 0. + +### linger\_timeout\_ms +Set TCP socket linger timeout before closing sockets (SO\_LINGER option). +The configured value is a timeout in milliseconds. Setting the value to 0 +will yield in abortive close (if the socket is closed from the server side). +Setting the value to -1 will turn off linger. +If the value is not set (or set to -2), CivetWeb will not set the linger +option at all. + +Note: For consistency with other timeouts, the value is configured in +milliseconds. However, the TCP socket layer usually only offers a timeout in +seconds, so the value should be an integer multiple of 1000. + +### lua\_preload\_file +This configuration option can be used to specify a Lua script file, which +is executed before the actual web page script (Lua script, Lua server page +or Lua websocket). It can be used to modify the Lua environment of all web +page scripts, e.g., by loading additional libraries or defining functions +required by all scripts. +It may be used to achieve backward compatibility by defining obsolete +functions as well. + +### lua\_script\_pattern `"**.lua$` +A pattern for files that are interpreted as Lua scripts by the server. +In contrast to Lua server pages, Lua scripts use plain Lua syntax. +An example can be found in the test directory. + +### lua\_server\_page\_pattern `**.lp$|**.lsp$` +Files matching this pattern are treated as Lua server pages. +In contrast to Lua scripts, the content of a Lua server pages is delivered +directly to the client. Lua script parts are delimited from the standard +content by including them between tags. +An example can be found in the test directory. + +### lua\_background\_script +Experimental feature, and subject to change. +Run a Lua script in the background, independent from any connection. +The script is started before network access to the server is available. +It can be used to prepare the document root (e.g., update files, compress +files, ...), check for external resources, remove old log files, etc. + +The Lua state remains open until the server is stopped. +In the future, some callback functions will be available to notify the +script on changes of the server state. See example lua script : +[background.lua](https://github.com/civetweb/civetweb/blob/master/test/background.lua). + +Additional functions available in background script : +sleep, root path, script name, isterminated + +### lua\_background\_script\_params `param1=1,param2=2` +Can add dynamic parameters to background script. +Parameters mapped to global 'mg' table 'params' field. + +### websocket\_root +In case civetweb is built with Lua and websocket support, Lua scripts may +be used for websockets as well. Since websockets use a different URL scheme +(ws, wss) than other http pages (http, https), the Lua scripts used for +websockets may also be served from a different directory. By default, +the document_root is used as websocket_root as well. + + +### access\_control\_allow\_origin `*` +Access-Control-Allow-Origin header field, used for cross-origin resource +sharing (CORS). +See the [Wikipedia page on CORS](http://en.wikipedia.org/wiki/Cross-origin_resource_sharing). + + +### access\_control\_allow\_methods `*` +Access-Control-Allow-Methods header field, used for cross-origin resource +sharing (CORS) pre-flight requests. +See the [Wikipedia page on CORS](http://en.wikipedia.org/wiki/Cross-origin_resource_sharing). + +If set to an empty string, pre-flights will not be supported directly by the server, +but scripts may still support pre-flights by handling the OPTIONS method properly. +If set to "*", the pre-flight will allow whatever method has been requested. +If set to a comma separated list of valid HTTP methods, the pre-flight will return +exactly this list as allowed method. +If set in any other way, the result is unspecified. + + +### access\_control\_allow\_headers `*` +Access-Control-Allow-Headers header field, used for cross-origin resource +sharing (CORS) pre-flight requests. +See the [Wikipedia page on CORS](http://en.wikipedia.org/wiki/Cross-origin_resource_sharing). + +If set to an empty string, pre-flights will not allow additional headers. +If set to "*", the pre-flight will allow whatever headers have been requested. +If set to a comma separated list of valid HTTP headers, the pre-flight will return +exactly this list as allowed headers. +If set in any other way, the result is unspecified. + + +### error\_pages +This option may be used to specify a directory for user defined error pages. +The error pages may be specified for an individual http status code (e.g., +404 - page requested by the client not found), a group of http status codes +(e.g., 4xx - all client errors) or all errors. The corresponding error pages +must be called error404.ext, error4xx.ext or error.ext, whereas the file +extention may be one of the extentions specified for the index_files option. +See the [Wikipedia page on HTTP status codes](http://en.wikipedia.org/wiki/HTTP_status_code). + +### tcp\_nodelay `0` +Enable TCP_NODELAY socket option on client connections. + +If set the socket option will disable Nagle's algorithm on the connection +which means that packets will be sent as soon as possible instead of waiting +for a full buffer or timeout to occur. + + 0 Keep the default: Nagel's algorithm enabled + 1 Disable Nagel's algorithm for all sockets + +### static\_file\_max\_age `3600` +Set the maximum time (in seconds) a cache may store a static files. + +This option will set the `Cache-Control: max-age` value for static files. +Dynamically generated content, i.e., content created by a script or callback, +must send cache control headers by themselfes. + +A value >0 corresponds to a maximum allowed caching time in seconds. +This value should not exceed one year (RFC 2616, Section 14.21). +A value of 0 will send "do not cache" headers for all static files. +For values <0 and values >31622400, the behavior is undefined. + +### strict\_transport\_security\_max\_age + +Set the `Strict-Transport-Security` header, and set the `max-age` value. +This instructs web browsers to interact with the server only using HTTPS, +never by HTTP. If set, it will be sent for every request handled directly +by the server, except scripts (CGI, Lua, ..) and callbacks. They must +send HTTP headers on their own. + +The time is specified in seconds. If this configuration is not set, +or set to -1, no `Strict-Transport-Security` header will be sent. +For values <-1 and values >31622400, the behavior is undefined. + +### decode\_url `yes` +URL encoded request strings are decoded in the server, unless it is disabled +by setting this option to `no`. + +### ssl\_verify\_peer `no` +Enable client's certificate verification by the server. + +### ssl\_ca\_path +Name of a directory containing trusted CA certificates.

All specified header lines will be sent. + +# Lua Scripts and Lua Server Pages +Pre-built Windows and Mac civetweb binaries have built-in Lua scripting +support as well as support for Lua Server Pages. + +Lua scripts (default extension: *.lua) use plain Lua syntax. +The body of the script file is not sent directly to the client, +the Lua script must send header and content of the web page by calling +the function mg.write(text). + +Lua Server Pages (default extensions: *.lsp, *.lp) are html pages containing +script elements similar to PHP, using the Lua programming language instead of +PHP. Lua script elements must be enclosed in `` blocks, and can appear +anywhere on the page. Furthermore, Lua Server Pages offer the opportunity to +insert the content of a variable by enclosing the Lua variable name in +`` blocks, similar to PHP. +For example, to print the current weekday name and the URI of the current +page, one can write: + +

+ Today is: + +

+

+ URI is +

+ +Lua is known for it's speed and small size. Civetweb currently uses Lua +version 5.2.4. The documentation for it can be found in the +[Lua 5.2 reference manual](http://www.lua.org/manual/5.2/). + + +Note that this example uses function `mg.write()`, which sends data to the +web client. Using `mg.write()` is the way to generate web content from inside +Lua code. In addition to `mg.write()`, all standard Lua library functions +are accessible from the Lua code (please check the reference manual for +details). Lua functions working on files (e.g., `io.open`) use a path +relative to the working path of the civetweb process. The web server content +is located in the path `mg.document_root`. +Information on the request is available in the `mg.request_info` +object, like the request method, all HTTP headers, etcetera. + +[page2.lua](https://github.com/civetweb/civetweb/blob/master/test/page2.lua) +is an example for a plain Lua script. + +[page2.lp](https://github.com/civetweb/civetweb/blob/master/test/page2.lp) +is an example for a Lua Server Page. + +Both examples show the content of the `mg.request_info` object as the page +content. Please refer to `struct mg_request_info` definition in +[civetweb.h](https://github.com/civetweb/civetweb/blob/master/include/civetweb.h) +to see additional information on the elements of the `mg.request_info` object. + +Civetweb also provides access to the [SQlite3 database](http://www.sqlite.org/) +through the [LuaSQLite3 interface](http://lua.sqlite.org/index.cgi/doc/tip/doc/lsqlite3.wiki) +in Lua. Examples are given in +[page.lua](https://github.com/civetweb/civetweb/blob/master/test/page.lua) and +[page.lp](https://github.com/civetweb/civetweb/blob/master/test/page.lp). + + +Civetweb exports the following functions to Lua: + +mg (table): + + mg.read() -- reads a chunk from POST data, returns it as a string + mg.write(str) -- writes string to the client + mg.include(filename, [pathtype]) -- include another Lua Page file (Lua Pages only) + -- pathtype can be "abs", "rel"/"file" or "virt[ual]" + -- like defined for SSI #include + mg.redirect(uri) -- internal redirect to a given URI + mg.onerror(msg) -- error handler, can be overridden + mg.version -- a string that holds Civetweb version + mg.document_root -- a string that holds the document root directory + mg.auth_domain -- a string that holds the HTTP authentication domain + mg.get_var(str, varname) -- extract variable from (query) string + mg.get_cookie(str, cookie) -- extract cookie from a string + mg.get_mime_type(filename) -- get MIME type of a file + mg.get_info(infotype) -- get server status information + mg.send_file(filename) -- send a file, including MIME type + mg.url_encode(str) -- URL encode a string + mg.url_decode(str, [form]) -- URL decode a string.

That context is used for +all Lua blocks within the page. That means, all Lua blocks on the same page +share the same context. If one block defines a variable, for example, that +variable is visible in all block that follow. + +## Websockets for Lua +Civetweb offers support for websockets in Lua as well. In contrast to plain +Lua scripts and Lua server pages, Lua websocket scripts are shared by all clients. + +Lua websocket scripts must define a few functions: + open(arg) -- callback to accept or reject a connection + ready(arg) -- called after a connection has been established + data(arg) -- called when the server receives data from the client + close(arg) -- called when a websocket connection is closed +All function are called with one argument of type table with at least one field +"client" to identify the client. When "open" is called, the argument table additionally +contains the "request_info" table as defined above. For the "data" handler, an +additional field "data" is available. The functions "open", "ready" and "data" +must return true in order to keep the connetion open. + +Lua websocket pages do support single shot (timeout) and interval timers. + +An example is shown in +[websocket.lua](https://github.com/civetweb/civetweb/blob/master/test/websocket.lua). + + +# Common Problems +- PHP doesn't work - getting empty page, or 'File not found' error.

As long as the `php` binary is installed, you can run CGI programs in command line mode (see the example below).

The returned code is stored as the status code in the access log, it is therefore recommended, although not mandatory to return a status code which matches the state of the request. + +### See Also + +* [`mg_set_auth_handler();`](mg_set_auth_handler.md) diff --git a/src/civetweb/docs/api/mg_set_user_connection_data.md b/src/civetweb/docs/api/mg_set_user_connection_data.md new file mode 100644 index 000000000..adafc2290 --- /dev/null +++ b/src/civetweb/docs/api/mg_set_user_connection_data.md @@ -0,0 +1,44 @@ +# Civetweb API Reference + +### `mg_set_user_connection_data( conn, data );` + +### Parameters + +| Parameter | Type | Description | +| :--- | :--- | :--- | +|**`conn`**|`struct mg_connection *`|connection to add the user data| +|**`data`**|`void *`|Pointer to the user data| + +### Return Value + +*none* + +### Description + +The function `mg_set_user_connection_data()` can be used to set a user defined +data pointer attached to a connection.

+=======
+Duktape
+=======
+
+Duktape is a small and portable Ecmascript E5/E5.1 implementation.  It is
+intended to be easily embeddable into C programs, with a C API similar in
+spirit to Lua's.
+
+Duktape supports the full E5/E5.1 feature set including errors, Unicode
+strings, and regular expressions, a subset of E6 features (e.g. Proxy
+objects), Khronos/ES6 ArrayBuffer/TypedView, and Node.js Buffer bindings.
+
+Duktape also provides a number of custom features such as error tracebacks,
+additional data types for better C integration, combined reference counting
+and mark-and sweep garbage collector, object finalizers, co-operative
+threads a.k.a. coroutines, tail calls, built-in logging and module frameworks,
+a built-in debugger protocol, function bytecode dump/load, and so on.
+
+You can browse Duktape programmer's API and other documentation at:
+
+* http://duktape.org/
+
+In particular, you should read the getting started section:
+
+* http://duktape.org/guide.html#gettingstarted
+
+More examples and how-to articles are in the Duktape Wiki:
+
+* http://wiki.duktape.org/
+
+Building and integrating Duktape into your project is very straightforward:
+
+* http://duktape.org/guide.html#compiling
+
+See Makefile.hello for a concrete example::
+
+  $ cd 
+  $ make -f Makefile.hello
+  [...]
+  $ ./hello
+  Hello world!
+  2+3=5
+
+To build an example command line tool, use the following::
+
+  $ cd 
+  $ make -f Makefile.cmdline
+  [...]
+
+  $ ./duk
+  ((o) Duktape
+  duk> print('Hello world!');
+  Hello world!
+  = undefined
+
+  $ ./duk mandel.js
+  [...]
+
+This distributable contains:
+
+* ``src/``: main Duktape library in a "single source file" format (duktape.c,
+  duktape.h, and duk_config.h).
+
+* ``src-noline/``: contains a variant of ``src/duktape.c`` with no ``#line``
+  directives which is preferable for some users.  See discussion in
+  https://github.com/svaarala/duktape/pull/363.
+
+* ``src-separate/``: main Duktape library in multiple files format.
+
+* ``config/``: genconfig utility for creating duk_config.h configuration
+  files, see: http://wiki.duktape.org/Configuring.html.
+
+* ``examples/``: further examples for using Duktape.  Although Duktape
+  itself is widely portable, some of the examples are Linux only.
+  For instance the ``eventloop`` example illustrates how ``setTimeout()``
+  and other standard timer functions could be implemented on Unix/Linux.
+
+* ``extras/``: utilities and modules which don't comfortably fit into the
+  main Duktape library because of footprint or portability concerns.
+  Extras are maintained and bug fixed code, but don't have the same version
+  guarantees as the main Duktape library.
+
+* ``polyfills/``: a few replacement suggestions for non-standard Javascript
+  functions provided by other implementations.
+
+* ``debugger/``: a debugger with a web UI, see ``debugger/README.rst`` and
+  https://github.com/svaarala/duktape/blob/master/doc/debugger.rst for
+  details on Duktape debugger support.  Also contains a JSON debug proxy
+  (one written in Node.js and another in DukLuv) to make talking to the
+  debug target easier.
+
+* ``licenses/``: licensing information.
+
+You can find release notes at:
+
+* https://github.com/svaarala/duktape/blob/master/RELEASES.rst
+
+This distributable contains Duktape version 1.5.2, created from git
+commit cad34ae155acb0846545ca6bf2d29f9463b22bbb (v1.5.2).
+
+Duktape is copyrighted by its authors (see ``AUTHORS.rst``) and licensed
+under the MIT license (see ``LICENSE.txt``).  String hashing algorithms are
+based on the algorithm from Lua (MIT license), djb2 hash, and Murmurhash2
+(MIT license).  Duktape module loader is based on the CommonJS module
+loading specification (without sharing any code), CommonJS is under the
+MIT license.
+
+Have fun!

+=================
+Duktape genconfig
+=================
+
+Overview
+========
+
+``genconfig`` is a helper script for coming up with a ``duk_config.h`` for
+compiling Duktape for your platform.
+
+To support this:
+
+* It creates a Duktape 1.2.x compatible ``duk_config.h`` with automatic
+  platform detection and ``DUK_OPT_xxx`` feature options.
+
+* It helps to create a ``duk_config.h`` for your platform/compiler
+  combination.  You can give a base configuration and then force certain
+  values manually based on a YAML configuration file.
+
+* It autogenerates documentation for config options (and Duktape 1.2.x
+  feature options) based on option metadata files written in YAML.
+
+Usage
+=====
+
+To create an autodetect duk_config.h header (compatible with Duktape 1.2.x)::
+
+    $ python config/genconfig.py --metadata config --output /tmp/duk_config.h \
+          autodetect-header
+
+To create a barebones duk_config.h header for a specific platform (easier to
+edit manually)::
+
+    $ python config/genconfig.py --metadata config --output /tmp/duk_config.h \
+          --platform linux --compiler gcc --architecture x64 \
+          barebones-header
+
+There are further commands to e.g. autogenerate config option documentation;
+see ``genconfig.py`` for details.

+#  Process Duktape option metadata and produce various useful outputs:
+#
+#    - duk_config.h with specific or autodetected platform, compiler, and
+#      architecture; forced options; sanity checks; etc
+#    - option documentation for Duktape 1.x feature options (DUK_OPT_xxx)
+#    - option documentation for Duktape 1.x/2.x config options (DUK_USE_xxx)
+#
+#  Genconfig tries to build all outputs based on modular metadata, so that
+#  managing a large number of config options (which is hard to avoid given
+#  the wide range of targets Duktape supports) remains maintainable.
+#
+#  Genconfig does *not* try to support all exotic platforms out there.
+#  Instead, the goal is to allow the metadata to be extended, or to provide
+#  a reasonable starting point for manual duk_config.h tweaking.
+#
+#  For Duktape 1.3 release the main goal was to autogenerate a Duktape 1.2
+#  compatible "autodetect" header from legacy snippets, with other outputs
+#  being experimental.  For Duktape 1.4 duk_config.h is always created from
+#  modular sources.

+=========================================
+Duktape debug client and JSON debug proxy
+=========================================
+
+Overview
+========
+
+Debugger web UI which connects to the Duktape command line tool or any other
+target supporting the example TCP transport (``examples/debug-trans-socket``)
+on Unix and Windows.
+
+Also provides a JSON debug proxy with a JSON mapping for the Duktape debug
+protocol.
+
+For detailed documentation of the debugger internals, see `debugger.rst`__.
+
+__ https://github.com/svaarala/duktape/blob/master/doc/debugger.rst
+
+Using the debugger web UI
+=========================
+
+Some prerequisites:
+
+* You'll need Node.js v0.10.x or newer.  Older Node.js versions don't support
+  the required packages.
+
+Compile Duktape command line tool with debugger support (for further options
+see http://wiki.duktape.org/FeatureOptions.html):
+
+* ``DUK_OPT_DEBUGGER_SUPPORT``
+
+* ``DUK_OPT_INTERRUPT_COUNTER``
+
+* ``DUK_CMDLINE_DEBUGGER_SUPPORT``
+
+The source distributable contains a Makefile to build a "duk" command with
+debugger support::
+
+    $ cd 
+    $ make -f Makefile.dukdebug
+
+The Duktape Git repo "duk" target has debugger support enabled by default::
+
+    $ make clean duk
+
+Start Duktape command line tool so that it waits for a debugger connection::
+
+    # For now we need to be in the directory containing the source files
+    # executed so that the 'fileName' properties of functions will match
+    # that on the debug client.
+
+    # Using source distributable
+    $ cd 
+    $ ./duk --debugger mandel.js
+
+    # Using Duktape Git repo
+    $ cd /tests/ecmascript/
+    $ ../../duk --debugger test-dev-mandel2-func.js
+
+Start the web UI::
+
+    # Must be in 'debugger' directory.
+
+    $ cd debugger/
+    $ make  # runs 'node duk_debug.js'
+
+Once the required packages are installed, the NodeJS debug client will be
+up and running.  Open the following in your browser and start debugging:
+
+* http://localhost:9092/
+
+The debug client automatically attaches to the debug target on startup.
+If you start the debug target later, you'll need to click "Attach" in the
+web UI.
+
+Using the JSON debug proxy
+==========================
+
+There are two JSON debug proxy implementations: one implemented in DukLuv
+and another in Node.js.
+
+DukLuv JSON proxy
+-----------------
+
+DukLuv (https://github.com/creationix/dukluv) is a small and portable event
+loop based on LibUV and Duktape with MIT license (like Duktape).  As such it's
+easy to embed in a custom debug client: you just include the DukLuv executable
+and the JSON proxy source file in your debug client.
+
+Install DukLuv:
+
+* Ensure ``cmake`` is installed
+
+* ``git clone https://github.com/creationix/dukluv.git``
+
+* ``git submodule init; git submodule update``
+
+* ``make``
+
+* Binary should appear in:
+
+  - ``./build/dukluv`` on Linux
+
+  - ``.\build\Debug\dukluv.exe`` on Windows
+
+Run the proxy::
+
+    # Using Makefile; autogenerates duk_debug_meta.json
+    # (You may need to edit DUKLUV in Makefile to point to your DukLuv)
+    $ make runproxydukluv
+
+    # Manually: see "dukluv duk_debug_proxy.js --help" for help
+    $ .../path/to/dukluv duk_debug_proxy.js
+
+Start Duktape command line (or whatever your target is)::
+
+    $ cd /tests/ecmascript/
+    $ ../../duk --debugger test-dev-mandel2-func.js
+
+Now connect to the proxy using e.g. telnet::
+
+    $ telnet localhost 9093
+
+The proxy will then connect to the target and you can start issuing commands::
+
+    $ telnet localhost 9093
+    Trying 127.0.0.1...
+    Connected to localhost.
+    Escape character is '^]'.
+    {"notify":"_TargetConnecting","args":["127.0.0.1",9091]}
+    {"notify":"_TargetConnected","args":["1 10499 v1.4.0-140-gc9a6c7c duk command built from Duktape repo"]}
+    {"notify":"Status","command":1,"args":[1,"test-dev-mandel2-func.js","global",58,0]}
+    {"request":"BasicInfo"}
+    {"reply":true,"args":[10499,"v1.4.0-140-gc9a6c7c","duk command built from Duktape repo",1]}
+    {"request":"Eval","args":["print('Hello world!'); 123;"]}
+    {"notify":"Print","command":2,"args":["Hello world!\n"]}
+    {"reply":true,"args":[0,{"type":"number","data":"405ec00000000000"}]}
+    [...]
+
+The proxy log provides dumps both JSON and dvalue binary traffic which is
+quite useful in development::
+
+    $ make runproxydukluv
+    Running Dukluv based debug proxy
+    "dukluv" duk_debug_proxy.js --log-level 2 --metadata duk_debug_meta.json

+Node.js JSON proxy
+------------------
+
+A Node.js-based JSON debug proxy is also provided by ``duk_debug.js``::
+
+    # Same prerequisites as for running the debug client
+    $ make runproxynodejs
+
+Start Duktape command line (or whatever your target is)::
+
+    $ cd /tests/ecmascript/
+    $ ../../duk --debugger test-dev-mandel2-func.js
+
+You can then connect to localhost:9093 and interact with the proxy.
+Here's an example session using telnet and manually typed in commands
+The ``-->`` (send) and ``<--`` (receiver) markers have been added for
+readability and are not part of the stream::
+
+    $ telnet localhost 9093
+    Trying 127.0.0.1...
+    Connected to localhost.

+    <-- {"notify":"Print","command":2,"args":["................................................................................\n"]}
+    [...]
+    <-- {"notify":"_Disconnecting"}
+
+A telnet connection allows you to experiment with debug commands by simply
+copy-pasting debug commands to the telnet session.  This is useful even if
+you decide to implement the binary protocol directly.
+
+The debug target used by the proxy can be configured with ``duk_debug.js``
+command line options.
+
+Source search path
+==================
+
+The NodeJS debug client needs to be able to find source code files matching
+code running on the target ("duk" command line).  **The filenames used on the
+target and on the debug client must match exactly**, because e.g. breakpoints
+are targeted based on the 'fileName' property of Function objects.
+
+The search path can be set using the ``--source-dirs`` option given to
+``duk_debug.js``, with the default search paths including only
+``../tests/ecmascript/``.
+
+The default search path means that if a function on the target has fileName
+``foo/bar.js`` it would be loaded from (relative to the duk_debug.js working
+directory, ``debugger/``)::
+
+    ../tests/ecmascript/foo/bar.js
+
+Similarly, if the filesystem contained::
+
+    ../tests/ecmascript/baz/quux.js
+
+the web UI dropdown would show ``baz/quux.js``.  If you selected that file
+and added a breakpoint, the breakpoint fileName sent to the debug target
+would be ``baz/quux.js``.
+
+.. note:: There's much to improve in the search path.  For instance, it'd
+          be nice to add a certain path to search but exclude files based
+          on paths and patterns, etc.
+
+Architecture
+============
+
+::
+
+    +-------------------+
+    | Web browser       |  [debug UI]
+    +-------------------+
+          |
+          | http (port 9092)
+          | socket.io
+          v
+    +-------------------+
+    | duk_debug.js      |  [debug client]
+    +-------------------+

+          |          ||
+          +----------||---- [example tcp transport] (port 9091)
+          |          ||     (application provides concrete transport)
+          |          ||
+          |          ||---- [debug protocol stream]
+          |          ||     (between debug client and Duktape)
+          |          ||
+    + - - | - - - - -|| - - +
+    :     v          ||     :
+    :  +-------------||-+   :  [target]
+    :  | application || |   :
+    :  +-------------||-+   :
+    :     ^          ||     :
+    :     |          ||     :   [debug API]
+    :     +----------||-------- debug transport callbacks
+    :     |          ||     :   (read, write, peek, read/write flush)
+    :     |          ||     :   implemented by application
+    :     |          \/     :
+    :  +----------------+   :
+    :  | Duktape        |   :
+    :  +----------------+   :
+    + - - - - - - - - - - - +
+
+The debug transport is application specific:
+
+* Duktape command line ("duk") and this debug client use an **example** TCP
+  transport as a concrete example.
+
+* It is entirely up to the application to come up with the most suitable
+  transport for its environment.  Different mechanisms will be needed for
+  Wi-Fi, serial, etc.
+
+The debug protocol running inside the transport is transport independent:
+
+* The debug protocol is documented in ``doc/debugger.rst``.
+
+* This debug client provides further concrete examples and clarifications
+  on how the protocol can be used.
+
+Using a custom transport
+========================
+
+Quite possibly your target device cannot use the example TCP transport and
+you need to implement your own transport.  You'll need to implement your
+custom transport both for the target device and for the debug client.
+
+Target device
+-------------
+
+Implement the debug transport callbacks needed by ``duk_debugger_attach()``.
+
+See ``doc/debugger.rst`` for details and ``examples/debug-trans-socket``
+for example running code for a TCP transport.
+
+Debug client alternative 1: duk_debug.js + custom TCP proxy
+-----------------------------------------------------------
+
+If you don't want to change ``duk_debug.js`` you can implement a TCP proxy
+which accepts a TCP connection from ``duk_debug.js`` and then uses your
+custom transport to talk to the target::
+
+   +--------------+   TCP   +-------+   custom   +--------+
+   | duk_debug.js | ------> | proxy | ---------> | target |
+   +--------------+         +-------+            +--------+
+
+This is a straightforward option and a proxy can be used with other debug
+clients too (perhaps custom scripts talking to the target etc).
+
+You could also use netcat and implement your proxy so that it talks to
+``duk_debug.js`` using stdin/stdout.
+
+Debug client alternative 2: duk_debug.js + custom NodeJS stream
+---------------------------------------------------------------
+
+To make ``duk_debug.js`` use a custom transport you need to:
+
+* Implement your own transport as NodeJS stream.  You can add it directly to
+  ``duk_debug.js`` but it's probably easiest to use a separate module so that
+  the diff to ``duk_debug.js`` stays minimal.
+
+* Change ``duk_debug.js`` to use the custom transport instead of a TCP
+  stream.  Search for "CUSTOMTRANSPORT" in ``duk_debug.js``.
+
+See:
+
+* http://nodejs.org/api/stream.html
+
+* https://github.com/substack/stream-handbook
+
+Debug client alternative 3: custom debug client
+-----------------------------------------------
+
+You can also implement your own debug client and debug UI with support for
+your custom transport.
+
+You'll also need to implement the client part of the Duktape debugger
+protocol.  See ``doc/debugger.rst`` for the specification and ``duk_debug.js``
+for example running code which should illustrate the protocol in more detail.
+
+The JSON debug proxy allows you to implement a debug client without needing
+to implement the Duktape binary debug protocol.  The JSON protocol provides
+a roughly 1:1 mapping to the binary protocol but with an easier syntax.

+=====================
+Hybrid pool allocator
+=====================
+
+Example allocator that tries to satisfy memory allocations for small sizes
+from a set of fixed pools, but always falls back to malloc/realloc/free if
+a larger size is requested or the pools have been exhausted.
+
+This may be useful to reduce memory churn when the platform allocator does
+not handle allocations for a lot of small memory areas efficiently.

+Allocator with memory wiping and red zones
+==========================================
+
+Example allocator that wipes memory on free and checks that no out-of-bounds
+writes have been made to bytes just before and after the allocated area.
+
+Valgrind is a better tool for detecting these memory issues, but it's not
+available for all targets so you can use something like this to detect
+memory lifecycle or out-of-bounds issues.

+Codepage conversion example
+===========================
+
+Example of how to convert an 8-bit input string (e.g. ISO-8859-1 or Windows
+codepage 1252) into CESU-8 without using an external library like iconv.
+
+This is useful e.g. when compiling non-UTF-8 source code which cannot be
+converted to UTF-8 (CESU-8) at build time.

+=========================================
+C++ exceptions for long control transfers
+=========================================
+
+Normally Duktape uses ``setjmp()`` / ``longjmp()`` or their variants for
+internal long control transfers.  One downside of these functions is that
+C++ automatic destructors (scope-based resource management, SBRM, a special
+case of RAII) in Duktape/C functions won't be executed which is awkward for
+C++ programmers.
+
+When ``DUK_USE_CPP_EXCEPTIONS`` (``DUK_OPT_CPP_EXCEPTIONS``) is defined, and
+both Duktape and application code is compiled using a C++ compiler, Duktape
+uses C++ ``try-catch`` and ``throw`` for internal long control transfers.
+This allows automatic destructors to run as expected.  The config option is
+not enabled by default because C++ exceptions are sometimes disabled even
+when a C++ compiler is used (e.g. for performance reasons).
+
+The ``cpp_exceptions.cpp`` example illustrates how C++ exceptions can be
+used in Duktape/C functions at the moment:
+
+* Duktape uses C++ try/catch/throw internally; this is not visible to user
+  code directly.
+
+* Automatic destructors (scope-based resource management) work as expected.
+
+* C++ exceptions can be used in Duktape/C functions normally, but user
+  exceptions must be caught before they reach Duktape.  If this is not
+  done, such exceptions are caught by Duktape and converted to API errors
+  (in other words, they won't propagate "through" Duktape at the moment).

+Debug transport using a simple socket connection
+================================================
+
+This example implements an example debug transport which uses a Linux or

+
+Files:
+
+* ``duk_trans_socket.h``: header file for the transport, used for both Linux
+  and Windows socket variants.
+
+* ``duk_trans_socket_unix.c``: implementation for Linux/Unix.
+
+* ``duk_trans_socket_windows.c``: implementation for Windows.
+
+Compile either Unix or Windows source file only.

+==================
+Eventloop examples
+==================
+
+Overview and usage
+==================
+
+A few examples on how an event loop can be implemented with Duktape, mainly
+illlustrating how the Duktape interface works (not how event loops should be
+built otherwise).
+
+To test (Linux only, perhaps other Unix)::
+
+  $ make
+  $ ./evloop curses-timers.js     # run with Ecmascript eventloop
+  $ ./evloop -c curses-timers.js  # run with C eventloop
+
+Implementation approaches
+=========================
+
+There are several approaches to implementation timers.  Here we demonstrate
+two main approaches:
+
+1. Using a C eventloop which calls into Javascript.  All the event loop state
+   like timers, sockets, etc, is held in C structures.
+   (See ``c_eventloop.c`` and ``c_eventloop.js``.)
+
+2. Using an Ecmascript eventloop which never returns.  All the event loop state
+   can be managed with Ecmascript code instead of C structures.  The Ecmascript
+   eventloop calls a Duktape/C helper to do the lowest level poll() call.
+   (See ``ecma_eventloop.js``.)
+
+Services provided
+=================
+
+The event loop API provided by both examples is the same, and includes:
+
+* Timers: setTimeout, clearTimeout, setInterval, clearInterval
+
+* Sockets: simple network sockets
+
+In addition there are a few synchronous API bindings which are not event loop
+related:
+
+* File I/O
+
+* Curses, for doing beautiful character graphics
+
+Limitations
+===========
+
+This is **not** a production quality event loop.  This is on purpose, to
+keep the example somewhat simple.  Some shortcomings include:
+
+* A production quality event loop would track its internal state (active
+  timers and sockets) much more efficiently.  In general memory usage and
+  code footprint can be reduced.
+
+* Buffer churn caused by allocating a new buffer for every socket read
+  should be eliminated by reusing buffers where appropriate.  Although
+  churn doesn't increase memory footprint with reference counting, it
+  is slower than reusing buffers and might increase memory fragmentation.
+
+* There is no way to suspend reading or writing in the example.  Adding
+  them is straightforward: the poll set needs to be managed dynamically.
+
+* The example uses poll() while one should use epoll() on Linux, kqueue()
+  on BSD systems, etc.
+
+* Timers are not very accurate, e.g. setInterval() does not try to guarantee
+  a steady schedule.  Instead, the next interval is scheduled after the
+  current callback has finished.  This is not the best behavior for some
+  environments, but avoids bunching callbacks.
+
+* Error handling is mostly missing.  Debug prints don't interact well
+  with curses.

+==============
+Duktape extras
+==============
+
+Extra modules and utilities.  Extras provide functionality that doesn't
+comfortably fit into the main Duktape library, perhaps for footprint or
+portability reasons, but are still useful for most users.
+
+Extras are maintained and will be bug fixed.  However, they don't have the
+same semantic versioning guarantees like the main Duktape library.  Extras
+may be dropped without warning as Duktape is versioned.  For instance, if
+an extra breaks due to Duktape changes and there is no time to fix it, the
+missing extra won't block a release and will be dropped.

+ *  Buffer writer (dynamic buffer only)

+ *  to reduce resizes.  You can ensure there is enough space beforehand and
+ *  then write for a while without further checks, relying on a stable data
+ *  pointer.  Spare handling is automatic so call sites only indicate how
+ *  much data they need right now.
+ *
+ *  There are several ways to write using bufwriter.  The best approach
+ *  depends mainly on how much performance matters over code footprint.
+ *  The key issues are (1) ensuring there is space and (2) keeping the
+ *  pointers consistent.  Fast code should ensure space for multiple writes
+ *  with one ensure call.  Fastest inner loop code can temporarily borrow
+ *  the 'p' pointer but must write it back eventually.
+ *
+ *  Be careful to ensure all macro arguments (other than static pointers like
+ *  'thr' and 'bw_ctx') are evaluated exactly once, using temporaries if
+ *  necessary (if that's not possible, there should be a note near the macro).

+ *  be followed by format arguments), they have a special prefix (DUK_STR_FMT_
+ *  and duk_str_fmt_).
+ *
+ *  On some compilers using explicit shared strings is preferable; on others
+ *  it may be better to use straight literals because the compiler will combine

+	 *
+	 *  In layout 1, the 'e_next' count is rounded to 4 or 8 on platforms
+	 *  requiring 4 or 8 byte alignment.  This ensures proper alignment
+	 *  for the entries, at the cost of memory footprint.  However, it's
+	 *  probably preferable to use another layout on such platforms instead.
+	 *
+	 *  In layout 2, the key and value parts are swapped to avoid padding
+	 *  the key array on platforms requiring alignment by 8.  The flags part
+	 *  is padded to get alignment for array entries.  The 'e_next' count does
+	 *  not need to be rounded as in layout 1.
+	 *
+	 *  In layout 3, entry values and array values are always aligned properly,
+	 *  and assuming pointers are at most 8 bytes, so are the entry keys.  Hash
+	 *  indices will be properly aligned (assuming pointers are at least 4 bytes).
+	 *  Finally, flags don't need additional alignment.  This layout provides
+	 *  compact allocations without padding (even on platforms with alignment
+	 *  requirements) at the cost of a bit slower lookups.
+	 *
+	 *  Objects with few keys don't have a hash index; keys are looked up linearly,
+	 *  which is cache efficient because the keys are consecutive.  Larger objects
+	 *  have a hash index part which contains integer indexes to the entries part.
+	 *
+	 *  A single allocation reduces memory allocation overhead but requires more
+	 *  work when any part needs to be resized.  A sliced allocation for entries
+	 *  makes linear key matching faster on most platforms (more locality) and
+	 *  skimps on flags size (which would be followed by 3 bytes of padding in
+	 *  most architectures if entries were placed in a struct).
+	 *
+	 *  'props' also contains internal properties distinguished with a non-BMP
+	 *  prefix.  Often used properties should be placed early in 'props' whenever
+	 *  possible to make accessing them as fast a possible.

+ *
+ *  DUK_D(x), DUK_DD(x), and DUK_DDD(x) are used together with log macros

+ *    DUK_DDD(DUK_DDDPRINT("foo"));

+ *  This approach is preferable to the old "double parentheses" hack because

+	 *
+	 *  The chain of bound functions is resolved in Section 15.3.4.5.2,

+	 *  However, we let duk_handle_call() handle the argument "piling"
+	 *  when the constructor is called.  The bound function chain is
+	 *  thus now processed twice.
+	 *
+	 *  When constructing new Array instances, an unnecessary object is
+	 *  created and discarded now: the standard [[Construct]] creates an
+	 *  object, and calls the Array constructor.  The Array constructor
+	 *  returns an Array instance, which is used as the result value for
+	 *  the "new" operation; the object created before the Array constructor
+	 *  call is discarded.
+	 *
+	 *  This would be easy to fix, e.g. by knowing that the Array constructor
+	 *  will always create a replacement object and skip creating the fallback
+	 *  object in that case.
+	 *
+	 *  Note: functions called via "new" need to know they are called as a
+	 *  constructor.  For instance, built-in constructors behave differently

+ *  Array built-ins
+ *
+ *  Note that most Array built-ins are intentionally generic and work even
+ *  when the 'this' binding is not an Array instance.  To ensure this,
+ *  Array algorithms do not assume "magical" Array behavior for the "length"
+ *  property, for instance.
+ *
+ *  XXX: the "Throw" flag should be set for (almost?) all [[Put]] and
+ *  [[Delete]] operations, but it's currently false throughout.  Go through
+ *  all put/delete cases and check throw flag use.  Need a new API primitive
+ *  which allows throws flag to be specified.
+ *
+ *  XXX: array lengths above 2G won't work reliably.  There are many places
+ *  where one needs a full signed 32-bit range ([-0xffffffff, 0xffffffff],
+ *  i.e. -33- bits).  Although array 'length' cannot be written to be outside
+ *  the unsigned 32-bit range (E5.1 Section 15.4.5.1 throws a RangeError if so)
+ *  some intermediate values may be above 0xffffffff and this may not be always
+ *  correctly handled now (duk_uint32_t is not enough for all algorithms).
+ *
+ *  For instance, push() can legitimately write entries beyond length 0xffffffff
+ *  and cause a RangeError only at the end.  To do this properly, the current
+ *  push() implementation tracks the array index using a 'double' instead of a
+ *  duk_uint32_t (which is somewhat awkward).  See test-bi-array-push-maxlen.js.
+ *
+ *  On using "put" vs. "def" prop
+ *  =============================
+ *
+ *  Code below must be careful to use the appropriate primitive as it matters
+ *  for compliance.  When using "put" there may be inherited properties in
+ *  Array.prototype which cause side effects when values are written.  When
+ *  using "define" there are no such side effects, and many test262 test cases
+ *  check for this (for real world code, such side effects are very rare).
+ *  Both "put" and "define" are used in the E5.1 specification; as a rule,
+ *  "put" is used when modifying an existing array (or a non-array 'this'
+ *  binding) and "define" for setting values into a fresh result array.
+ *
+ *  Also note that Array instance 'length' should be writable, but not
+ *  enumerable and definitely not configurable: even Duktape code internally
+ *  assumes that an Array instance will always have a 'length' property.
+ *  Preventing deletion of the property is critical.

+ *  TypedArray.prototype.set()
+ *
+ *  TypedArray set() is pretty interesting to implement because:
+ *
+ *    - The source argument may be a plain array or a typedarray.  If the
+ *      source is a TypedArray, values are decoded and re-encoded into the
+ *      target (not as a plain byte copy).  This may happen even when the
+ *      element byte size is the same, e.g. integer values may be re-encoded
+ *      into floats.
+ *
+ *    - Source and target may refer to the same underlying buffer, so that
+ *      the set() operation may overlap.  The specification requires that this
+ *      must work as if a copy was made before the operation.  Note that this
+ *      is NOT a simple memmove() situation because the source and target
+ *      byte sizes may be different -- e.g. a 4-byte source (Int8Array) may
+ *      expand to a 16-byte target (Uint32Array) so that the target overlaps
+ *      the source both from beginning and the end (unlike in typical memmove).
+ *
+ *    - Even if 'buf' pointers of the source and target differ, there's no
+ *      guarantee that their memory areas don't overlap.  This may be the
+ *      case with external buffers.
+ *
+ *  Even so, it is nice to optimize for the common case:
+ *
+ *    - Source and target separate buffers or non-overlapping.
+ *
+ *    - Source and target have a compatible type so that a plain byte copy
+ *      is possible.  Note that while e.g. uint8 and int8 are compatible
+ *      (coercion one way or another doesn't change the byte representation),
+ *      e.g. int8 and uint8clamped are NOT compatible when writing int8
+ *      values into uint8clamped typedarray (-1 would clamp to 0 for instance).

+	 *    Avoid year 1970 and 2038 as some conversions start to fail, at
+	 *    least on some platforms.  Avoiding 1970 means that there are
+	 *    currently DST discrepancies for 1970.
+	 *
+	 *  - Create a UTC and local time breakdowns from 't'.  Then create
+	 *    a time_t using gmtime() and localtime() and compute the time
+	 *    difference between the two.
+	 *
+	 *  Equivalent year mapping (E5 Section 15.9.1.8):
+	 *
+	 *    If the host environment provides functionality for determining
+	 *    daylight saving time, the implementation of ECMAScript is free
+	 *    to map the year in question to an equivalent year (same
+	 *    leap-year-ness and same starting week day for the year) for which
+	 *    the host environment provides daylight saving time information.
+	 *    The only restriction is that all equivalent years should produce
+	 *    the same result.
+	 *
+	 *  This approach is quite reasonable but not entirely correct, e.g.
+	 *  the specification also states (E5 Section 15.9.1.8):
+	 *
+	 *    The implementation of ECMAScript should not try to determine
+	 *    whether the exact time was subject to daylight saving time, but
+	 *    just whether daylight saving time would have been in effect if
+	 *    the _current daylight saving time algorithm_ had been used at the
+	 *    time.  This avoids complications such as taking into account the
+	 *    years that the locale observed daylight saving time year round.
+	 *
+	 *  Since we rely on the platform APIs for conversions between local
+	 *  time and UTC, we can't guarantee the above.  Rather, if the platform
+	 *  has historical DST rules they will be applied.  This seems to be the
+	 *  general preferred direction in Ecmascript standardization (or at least
+	 *  implementations) anyway, and even the equivalent year mapping should
+	 *  be disabled if the platform is known to handle DST properly for the
+	 *  full Ecmascript range.
