Embed a web-server that can handle multiple requests at the same time #14

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
Seems like the PHP built-in webserver is not multi-threaded, it
can handle only one request at the same time, this can be a problem
when executing scripts that take a significant amount of time. Take 
for example this scenario:

test1.php
---------
{{{
<?php
sleep(5);
print("test1 finished.");
?>
}}}

test2.php
---------
{{{
<?php
print("test2 finished.");
?>
}}}

Run test1.php & test2.php, you will see that you have to wait five
seconds before test2.php is executed, as test1.php has made the
web-server busy.

The same problem exists when using direct PHP API calls, see Issue 3.

Problem also exists with the Thread Safe version of PHP.

One of the options is to embed embed a web-server like Mongoose, which 
is written in C,only 140 KB, with CGI support, it is cross-platform and 
MIT licensed, this is the only option for Internet Explorer engine:

http://en.wikipedia.org/wiki/Mongoose_(web_server)

Wich Chrome we can implement a custom scheme handler, thus making web-server
an optional thing, we could go with direct PHP API calls to execute scripts,
but this would have to be done in a multi-threaded manner, CEF would need to
have a multi-threaded message loop.

Mongoose official website is at:

Mongoose PHP example (available in Downloads) comes with a Thread Safe
version of PHP, as I see "php5ts.dll".

I've tested test1.php and test2.php with Mongoose and it works great.

The question is whether we should embed Mongoose directly in our application,
or distribute "Mongoose.exe" along with "mongoose.conf" & "php-cgi.exe". When
running Mongoose.exe I don't see php-cgi.exe in the processes, maybe if we
embed through the C API we won't have any additional processes except the
"phpdesktop-msie.exe", that would be great, if anything hangs up there won't
be any gargage still running in the background.

"php-cgi.exe" appears in processes only while php script is running.

PHP web-server is not reliable, it sometimes doesn't start for 
unknown reason.

Mongoose allows us to log the coming http requests directly to application's
debugging console.

Mongoose options:
https://github.com/valenok/mongoose/wiki/Manual

We might consider adding these to settings.json:
  access_log_file
  enable_directory_listing
  error_log_file
  extra_mime_types
  num_threads
  url_rewrite_patterns

Create a separate issue for adding this options.
