OpenResty - General-purpose web service platform for web applications
This document describes OpenResty 0.0.9 released on Mar 5, 2008.
This module implements the server-side OpenResty web service protocol. It provides scriptable and extensible web services for both server-side and client-side (AJAX only) web applications.
Currently this module can serve as a public web interface to a distributive or desktop PostgreSQL databases. In particular, it provides models, views, roles, captchas to the users.
But note that OpenResty is not a web application framework like Jifty.
We're already running an instance of the OpenResty server on our Yahoo! China's production machines:
http://resty.eeeeworks.org/=/version
And there're several (pure-client-side) web sites alreadying taking advantage of the services:
http://blog.agentzh.org
http://www.yisou.com/opi/post.html
This library is still in pre-alpha stage and the API is still in flux. We're just following the "release early, releaes often" guideline. So please check back often ;)
SETUP TEST ENVIRONMENT:
This is a basic guideline for settting up an OpenResty server on your own machine. Someone has succeeded in setting up one on Windows XP using ActivePerl 5.8.8. The normal development environment is Linux though. If you have any particular question, feel free to ask us by sending mails to agentzh@yahoo.cn :)
Grab the openresty package and unpack it in some place, let's say it's openresty.
Enter the openresty directory, run "perl Makefile.PL" to check missing dependencies:
$ cd openresty $ perl Makefile.PL $ sudo make # This will install missing dependencies
To run "make test" or "make debug", you need to have lighttpd and PostgreSQL database installed.
for PostgreSQL database, you need to prepare a PostgreSQL account (i.e., 'agentzh); and you need to create an empty database (i.e. test), and you need to create a store precedure language plpgsql for that database, contact your PostgreSQL DBA for it or read PostgreSQL manuel.
Basically, they are command like:
$ createdb test $ createuser -P agnetzh $ createlang plpgsql test
Edit your etc/site_openresty.conf file, change the configure settings under [backend] section according to your previous settings. The default settings look like this:
[backend] type=Pg host=localhost user=agentzh password=agentzh database=test
Most of the time, you need to change the last 3 lines unless you're using exactly the same user, password, and database name.
Give read/write access to lighttpd's log file (optional):
$ chmod 777 /var/log/lighttpd/error.log $ chmod 777 /var/log/lighttpd
For the Pg backend, one need to create the "anonymous" role in your database (like "test"):
$ createuser anonymouse test
Create a "tester" user account for our test suite in OpenResty (drop it if it already exists):
$ bin/openresty deluser tester $ bin/openresty adduser tester
Give a password (say, blahblahblah) to its Admin role. Update your etc/site_openresty.conf to reflect your these settings:
[test_suite] use_http=0 server=tester:blahblahblah@localhost
Now you can already run the test suite without a lighttpd server:
$ prove -Ilib -Iinc -r t
Sample lighttpd configuration:
# lighttpd.conf server.modules = ( "mod_fastcgi", ... ) fastcgi.server = ( "/=" => ( "openresty" => ( "socket" => "/tmp/openresty.socket", "check-local" => "disable", "bin-path" => "/PATH/TO/YOUR/bin/openresty", "bin-environment" => ( "OPENAPI_URL_PREFIX" => "", "OPENAPI_COMMAND" => "fastcgi", ), "min-procs" => 1, "max-procs" => 5, "max-load-per-proc" => 1, "idle-timeout" => 20, ) ) )
And also make sure the following line is commented out:
# url.access-deny = ( "~", ".inc" )
HOW TO TEST ONE SPECIFIC TEST SUITE FILE
It's also possible to debug a simple .t file, for instance,
make t/01-sanity.t -f dev.mk
Or use prove to test a remote OpenResty server, for example:
OPENAPI_FRONTEND=10.62.136.86 prove t/0*.t
where 10.62.136.86 is the IP (or hostname or URL) of your OpenResty server being tested.
To test the Pg cluster rather than the desktop Pg, change your etc/site_openresty.conf:
[backend] type=PgFarm
and also set other items in the same group if necessary.
FOR DEVELOPER:
bin/ directory is the where CGI entry openresty located doc/ directory containing OpenResty spec lib/OpenResty/ directory contain all the code needed to run OpenResty lib/OpenResty/OpenResty.pm contain the code stub for OpenResty protocol lib/OpenResty/Limits.pm are those hard limits located, we limit the number of different objects (model, row, view etc.) a user could create by default lib/OpenResty/Backend contain all the code to initialize OpenResty meta tables and code to access different database, for now we support Postgres stand alone database and PostgreSQL cluster lib/OpenResty/Backend/Pg.pm OpenResty PostgreSQL stand alone database access code lib/OpenResty/Backend/PgFarm.pm OpenResty PostgreSQL cluster database access code lib/OpenResty/Handler contain all handler methods OpenResty supported, these methods are moved from lib/OpenResty.pm due to code refactor; method name looks like HTTP_METHOD_some_sub_name. lib/SQL classes/methods to generate SQL query (in string form), use OO to encapsulate SQL query generation lib/SQL/Statement.pm base class lib/SQL/Select.pm class and methods to generate SELECT statement lib/SQL/Insert.pm class and methods to generate INSERT statement lib/SQL/Update.pm class and methods to generate UPDATE statement lib/MiniSQL/ directory conatining our mini-sql parser code, now only SELECT support t/ directory containing OpenResty test suite, use `make test' to run the test, read above on how to setup test environment
