This is *very* bad. - * - * I.e. we should take a conservative approach, and only set non- - * blocking mode when we a) need to, and b) are reasonably certain - * that it won't be a problem. And as in the example above, the problem - * occurs when input fd and output fd point to different "things". - * - * However, determining that they are not just the same "type" of - * "thing", but actually the same instance of that type of thing, is - * unreasonably complex in many/most cases. - * - * Also, with pipes, sockets, and fifos it's far from obvious that the - * user *wants* non-blocking output: If you're running erlang inside - * some complex pipeline, you're probably not running a real-time system - * that must never stop, but rather *want* it to suspend if the output - * channel is "full". - * - * So, the bottom line: We will only set the output fd non-blocking if - * it points to a tty, and either a) the input fd also points to a tty, - * or b) we can make sure that setting the output fd non-blocking - * doesn't interfere with someone else's input, via a somewhat milder - * kludge than the above. - * - * Also keep in mind that while this code is almost exclusively run as - * a result of an erlang open_port({fd,0,1}, ...), that isn't the only - * case - it can be called with any old pre-existing file descriptors, - * the relations between which (if they're even two) we can only guess - * at - still, we try our best... - * - * Added note OTP 18: Some systems seem to use stdout/stderr to log data - * using unix pipes, so we cannot allow the system to block on a write. - * Therefore we use an async thread to write the data to fd's that could - * not be set to non-blocking. When no async threads are available we - * fall back on the old behaviour. - * - * Also the guarantee about what is delivered to the OS has changed. - * Pre 18 the fd driver did no flushing of data before terminating. - * Now it does. This is because we want to be able to guarantee that things - * such as escripts and friends really have outputted all data before - * terminating.

This is *very* bad. + * + * I.e. we should take a conservative approach, and only set non- + * blocking mode when we a) need to, and b) are reasonably certain + * that it won't be a problem. And as in the example above, the problem + * occurs when input fd and output fd point to different "things". + * + * However, determining that they are not just the same "type" of + * "thing", but actually the same instance of that type of thing, is + * unreasonably complex in many/most cases. + * + * Also, with pipes, sockets, and fifos it's far from obvious that the + * user *wants* non-blocking output: If you're running erlang inside + * some complex pipeline, you're probably not running a real-time system + * that must never stop, but rather *want* it to suspend if the output + * channel is "full". + * + * So, the bottom line: We will only set the output fd non-blocking if + * it points to a tty, and either a) the input fd also points to a tty, + * or b) we can make sure that setting the output fd non-blocking + * doesn't interfere with someone else's input, via a somewhat milder + * kludge than the above. + * + * Also keep in mind that while this code is almost exclusively run as + * a result of an erlang open_port({fd,0,1}, ...), that isn't the only + * case - it can be called with any old pre-existing file descriptors, + * the relations between which (if they're even two) we can only guess + * at - still, we try our best... + * + * Added note OTP 18: Some systems seem to use stdout/stderr to log data + * using unix pipes, so we cannot allow the system to block on a write. + * Therefore we use an async thread to write the data to fd's that could + * not be set to non-blocking. When no async threads are available we + * fall back on the old behaviour. + * + * Also the guarantee about what is delivered to the OS has changed. + * Pre 18 the fd driver did no flushing of data before terminating. + * Now it does. This is because we want to be able to guarantee that things + * such as escripts and friends really have outputted all data before + * terminating.

This in turn - means that you have to supply the raw beam arguments to the emulator - when starting. Fortunately <c>erl</c> on Unix/Windows has a - undocumented flag called <c>-emu_args_exit</c> that can be used to - figure out what the arguments to beam look like. For example:</p> - <code># erl +Mut false +A 10 +S 4:4 +Muycs256 +P 2096 +Q 2096 -emu_args_exit --Mut -false --A -10 --S -4:4 --Muycs256 --P -2096 --Q -2096 --- --root -/usr/local/lib/erlang --progname -erl --- --home -/home/erlang ---</code> - <p> - The arguments are printed on separate lines to make it possible to know - what has to be quoted with ". Each line is one quotable unit. - So taking the arguments above you can supply them to pm_create or - just execute directly on the command line. For example:</p> - <code>rtose@acp3400> pm_install erlang /mst/erlang/erts-6.0/bin/beam.smp -rtose@acp3400> pm_create -c ARGV="-Mut false -A 10 -S 4:4 -Muycs256 -P 2096 -Q 2099 -- -root /mst/erlang -progname erl -- -home /mst/erlang --" erlang -pid: 0x110059 -rtose@acp3400> pm_start 0x110059</code> - <p> - Also note that since we are running erl to figure out the arguments on a - separate machine the paths have to be updated. In the example above - <c>/usr/local/lib/erlang</c> was replaced by <c>/mst/erlang/</c>. The - goal is to in future releases not have to do the special argument handling - but for now (OTP 17.0) you have to do it. - </p> - <note> - Because of a limitation in the way the OSE handles stdio when starting - load modules using pm_install/create the Erlang shell only reads every - other command from stdin. However if you start Erlang using run_erl - you do not have this problem. So it is highly recommended that you - start Erlang using run_erl. - </note> - </section> - - <section> - <title>run_erl and to_erl</title> - <p> - In OSE run_erl and to_erl are combined into a single load module called - run_erl_lm. Installing and starting the load module will add two new - shell commands called run_erl and to_erl. They work in exactly the same - way as the unix variants of run_erl and to_erl, except that the read - and write pipes have to be placed under the /pipe vm. One additional - option also exists to run_erl on ose: - <taglist> - <tag><c>-block Name</c></tag> - <item>The name of the install handle and block that will be created/used by - installing and exectuting the first part of the command. If nothing - if given the basename of the load module will be used for this value. - Example: - <code>pm_install erlang /path/to/erlang/vm/beam.smp -run_erl -daemon -block erlang /pipe/ /mst/erlang_logs/ "beam.smp -A 1 -- -root /mst/erlang -- -home /mst --"</code> - </item> - </taglist> - The same argument munching as when starting Erlang/OTP without run_erl - has to be done. If <c>-daemon</c> is given then all error printouts - are sent to the ramlog. - See also - <seealso marker="erts:run_erl">run_erl</seealso> for more details. - </p> - <p> - Below is an example of how to get started with <c>run_erl_lm</c>. - <code>rtose@acp3400> pm_install run_erl_lm /mst/erlang/erts-6.0/bin/run_erl_lm -rtose@acp3400> pm_create run_erl_lm -pid: 0x1c005d -rtose@acp3400> pm_start 0x1c005d -rtose@acp3400> mkdir /mst/erlang_log -rtose@acp3400> run_erl -daemon /pipe/ /mst/erlang_log/ "/mst/erlang/erts-6.0/bin/beam.smp -A 1 -- -root /mst/erlang -- -home /mst --" -rtose@acp3400> to_erl -Attaching to /pipe/erlang.pipe.1 (^C to exit) -os:type(). -{ose,release} -2> -'to_erl' terminated.</code> - Note that Ctrl-C is used instead of Ctrl-D to exit the to_erl shell. - </p> - </section> - - <section> - <title>epmd</title> - <p> - In OSE epmd will not be started automatically so if you want to use - Erlang distribution you have to manually start epmd. - </p> - </section> - - <section> - <title>VM Process Priorities</title> - <p> - It is possible to set the priorities you want for the OSE processes that - thr emulator creates in the lmconf.

The api in the module - is very similar to the native OSE api, so for details of how the - functions work please refer to the official OSE documenation. Below - is an example usage of the API. - </p> - <code>1> P1 = ose:open("p1"). -#Port>0.344> -2> ose:hunt(P1,"p2"). -{#Port>0.344>,1} -3> P2 = ose:open("p2"). -#Port>0.355> -4> flush(). -Shell got {mailbox_up,#Port>0.344>,{#Port>0.344>,1},852189} -ok -5> ose:listen(P1,[1234]). -ok -6> ose:send(P2,ose:get_id(P1),1234,>>"hello">>). -ok -7> flush(). -Shell got {message,#Port>0.344>,{852189,1245316,1234,>>"hello">>}} -ok</code> - </section> - - <marker id="driver"></marker> - <section> - <title>Signals in a Linked-in driver</title> - <p> - Writing Linked-in drivers for OSE is very similar to how it is done - for Unix/Windows. It is only the way in which the driver subscribes - and consumed external events that is different. In Unix (and Windows) - file descriptiors (and Event Objects) are used to select on. On OSE - we use signals to deliver the same functionality. There are two large - differences between a signal and an fd. - </p> - <p> - In OSE it is not possible for a signal number to be a unique identifier - for a resource in the same way as an fd is. For example; let's say we - implement a driver that does an asynchronous hunt that uses signal - number 1234 as the hunt_sig. If we want to be able to have multiple - hunt ports running at the same time we have to have someway of routing - the signal to the correct port. This is achieved by supplying a secondary - id that can be retrieved through the meta-data or payload of the signal, - e.g: - <code>ErlDrvEvent event = erl_drv_ose_event_alloc(1234,port,resolver);</code> - The event you get back from - <seealso marker="ose_erl_driver#erl_drv_ose_event_alloc"> - erl_drv_ose_event_alloc</seealso> can then be used by - <seealso marker="erts:erl_driver#driver_select">driver_select</seealso> - to subscribe to signals. The first argument is just the signal number - that we are interested in. The second is the id that we choose to use, - in this case the port id that we got in the - <seealso marker="erts:driver_entry#start">start</seealso> callback is - used. The third argument is a function pointer to a function that can - be used to figure out the id from a given signal. The fourth argument can - point to any additional data you might want to associate with the event. - There is a complete. You can examine the data contained in the event with - <seealso marker="ose_erl_driver#erl_drv_ose_event_fetch">erl_drv_ose_event_fetch</seealso> - , eg: - <code>erl_drv_ose_event_fetch(event, &signal, &port, (void **)&extra);</code> - example of what this could look like in - <seealso marker="#example">the next section</seealso>. - <note>It is very important to issue the driver_select call before - any of the signals you are interested in are sent. If driver_select - is called after the signal is sent, there is a high probability that it - will be lost.</note> - </p> - <p> - The other difference from unix is that in OSE the payload of the event - (i.e. the signal data) is already received when the ready_output/input - callbacks are called. This means that you access the data of a signal - by calling <seealso marker="ose_erl_driver#erl_drv_ose_get_signal"> - erl_drv_ose_get_signal</seealso>. Additionally multiple signals might be - associated with the event, so you should call - <seealso marker="ose_erl_driver#erl_drv_ose_get_signal"> - erl_drv_ose_get_signal</seealso> until <c>NULL</c> is returned. - </p> - </section> - - <marker id="example"></marker> - <section> - <title>Example Linked-in driver</title> -<code>#include "erl_driver.h" -#include "ose.h" - -struct huntsig { - SIGSELECT signo; - ErlDrvPort port; -}; - -union SIGNAL { - SIGSELECT signo; - struct huntsig; -} - -/* Here we have to get the id from the signal.

The *.tool - file contains a version identifier and a list of tuples which - is the configuration data. The version identifier specifies - the *.tool file version, i.e. not the version of - webtool. Currently the only valid version is "1.2" and the - only valid configuration tag is - <c>config_func</c>. <c>config_func</c> specifies which - function WebTool must call to get further configuration data - for the tool. This means that a *.tool file generally must - look like this:</p> - <code type="none"> - {version,"1.2"}. - [{config_func,{Module,Function,Arguments}}]. </code> - <p><c>Module</c> is the name of the module where the callback - function is defined. <c>Function</c> is the name of the - callback function, and <c>Arguments</c> is the list of - arguments to the callback function.</p> - </section> - - <section> - <title>The configuration function</title> - <p>The *.tool file points out a configuration function. This - function must return a list of configuration parameters (see - the Reference Manual for <seealso marker="webtool">webtool</seealso>).</p> - <p>The <c>web_data</c> parameter is mandatory and it specifies - the name of the tool and the link to the tool's start - page. All other parameters are optional.</p> - <p>If the tool requires any processes to run, the <c>start</c> - parameter specifies the function that WebTool must call in - order to start the process(es).</p> - <p>The <c>alias</c> parameters are passed directly on to the - webserver (INETS). The webserver has three ways to create - dynamic web pages CGI, Eval Scheme and Erl Scheme. All tools - running under WebTool must use Erl Scheme.</p> - <p>Erl Scheme tries to resemble plain CGI. The big difference is - that Erl Scheme can only execute Erlang code. The code will - furthermore be executed on the same instance as the webserver.</p> - <p>An URL which calls an Erlang function with Erl Scheme can have - the following syntax:</p> - <code type="none"><![CDATA[ -http://Servername:Port/ErlScriptAlias/Mod/Func<?QueryString> ]]></code> - <p>An <c>alias</c> parameter in the configuration function can be - an ErlScriptAlias as used in the above URL. The definition of - an ErlScriptAlias shall be like this:</p> - <p><c>{alias,{erl_alias,Path,[Modules]}}</c>, e.g.</p> - <p><c>{alias,{erl_alias,"/testtool",[helloworld]}}</c></p> - <p>The following URL will then cause a call to the function - helloworld:helloworld/2 (if WebTool is started with default - settings i.e. servername "localhost" and port 8888):</p> - <p><c>http://localhost:8888/testtool/helloworld/helloworld</c></p> - <p>Note that the module <c>helloworld</c> must be in the code - path of the node running WebTool.</p> - <p>Functions that are called via the Erl Scheme must take two - arguments, <c>Environment</c> and <c>Input</c>. - </p> - <list type="bulleted"> - <item><c>Environment</c> is a list of key/value tuples.</item> - <item><c>Input</c> is the part of the URL after the "?", i.e. the - part of the URL containing name-value pairs. If the page was - called with the URL: - <br></br> -<c><![CDATA[http://localhost:8888/testtool/helloworld/helloworld?input1=one&input2=two]]></c> <br></br> -<c>Input</c> will be the string - <c><![CDATA["input1=one&input2=two"]]></c>. In the module - <c>httpd</c> in the INETS application there is a function - <c>parse_query</c> which will parse such a string and return - a list of key-value tuples.</item> - </list> - <p>An <c>alias</c> parameter in the configuration function can - also be a normal path alias. This can e.g. be used to point - out a directory where HTML files are stored. The following - definition states that the URL - <c>http://localhost:8888/mytool_home/</c> really points to the - directory <c>/usr/local/otp/lib/myapp-1.0/priv</c>:</p> - <p><c>{alias,{"/mytool_home","/usr/local/otp/lib/myapp-1.0/priv"}}</c></p> - <p>See the INETS documentation, especially the module - <c>mod_esi</c>, for a more in depth coverage of the Erl Scheme.</p> - </section> - - <section> - <title>A small example</title> - <p>A Hello World example that uses Erl Scheme would look like - this. Note that this example does not have a process running - and thus does not need a <c>start</c> parameter in the - configuration function. - </p> - <p><em>helloworld.erl:</em></p> - <pre> - -module(helloworld). - -export([config_data/0]). - -export([helloworld/2]). - - config_data()-> - {testtool, - [{web_data,{"TestTool","/testtool/helloworld/helloworld"}}, - {alias,{erl_alias,"/testtool",[helloworld]}}]}. - - helloworld(_Env,_Input)-> - [header(),html_header(),helloworld_body(),html_end()]. - - header() -> - header("text/html"). - - header(MimeType) -> - "Content-type: " ++ MimeType ++ "\r\n\r\n". - - html_header() -> - "<HTML> - <HEAD> - <TITLE>Hello world Example </TITLE> - </HEAD>\n". - - helloworld_body()-> - "<BODY>Hello World</BODY>". - - html_end()-> - "</HTML>". - </pre> - <p>To use this example with WebTool a *.tool file must be created - and added to a directory in the current path, e.g. the same - directory as the compiled <c>helloworld.beam</c>.</p> - <p><em>testtool.tool:</em></p> - <code type="none"> - {version,"1.2"}. - [{config_func, {helloworld,config_data,[]}}]. - </code> - <p>When <c>helloworld.erl</c> is compiled, start WebTool by - calling the function <c>webtool:start()</c> and point your - browser to <em>http://localhost:8888/</em>.
