Ruby Application Server

We are proud to announce release of WebROaR v0.7.0 with upgraded Admin Panel and few bug fixes.

There is no change to core functionality of the server. To make the server compatible with latest Rubygems, we have upgraded Admin Panel to Rails 3.0.9.

We are happy to announce the release of WebROaR v0.6.1 with a couple of new features and critical bug fixes.

Now the users can send their valuable feedback, and report any bug from "Contact Us" page of the Admin Panel. For that you need to configure mail setting from "Configuration" page.

This release added support to disable Admin Panel and Analytics feature. These features can be controlled from 'conf/serverinternalconfig.yml' file.

Previous version of Admin Panel shows backtrace and environment details of the last occurred exception. But now it shows backtrace and environment details from all the exceptions.

We are happy to announce the release of WebROaR v0.5.0 with some new features, enhancement and fixes.

This release added support to filter out known exceptions at application level and these filtered exceptions are listed in Permanently Ignored list.

The previous version of the server supports only 'deflate' encoding for static assets. Now, 'gzip' encoding is also supported with this release.

We have also added command line support to add/remove an application form its root directory. User can simply deploy an application from its root directory by executing command 'webroar add'. It would deploy the application using default parameters. Of course, you can pass parameters to overwrite default parameters.

WebROaR is under continuous development. We are happy to announce release of WebROaR v0.4.0 which contains new features, enhancements and bug fixes.

Previous versions of WebROaR were supporting 'gzip' and 'deflate' content encoding for dynamic response. In this release, we have added support for 'deflate' content encoding of static assets. By default content encoding is supported for content type 'javascript|css|xml|text' having actual content size greater than 1KB and less than 10MB for all the user agent. Content type, size and user agent is configurable through 'config.yml' file.

We are happy to announce the release of WebROaR v0.3.1 that supports Zero Downtime Application Upgrades.

The previous versions of the server already allowed restart of a single application at a time without affecting the other apps hosted on it. We have further improved the logic now, to ensure even the particular application being restarted, does not become unavailable at any time.

WebROaR v0.2.6 gem is now available with the following fixes:

• Updated messages for HTTP status codes 400, 404, 405, 500 and 501.
• Fixed buffer overflow by allocating enough memory to hold REQUEST_PATH + Application-Path in the request resolver for static assets.
• Improved the logic for detection of ruby shared library prerequisite.
• Started using RUBY_INSTALL_NAME for detecting ruby during installation.
• Added validation for search results file created while generating service script. Installation would continue even if server cannot be installed as a service.
• Corrected example for the 'Headers' section in the config file.
• Removed 'SIGCHLD' handler from the worker process - Fixes the incorrect exit status issue for a shell command executed using backquote method of ruby.
• Added HTTP Date header when the HTTP response status is 100.
• Used _POSIX_C_SOURCE macro to identify whether the file variable is a pointer to a file or a socket fd.
• Corrected return type of 'send_static_worker_pid' method, if YAML parser returns NULL value.
• Corrected time slider based analytics graphs issue when they were being seen after 2300 hrs.
• Correctly implemented Rack specification for the Response Body. This fixes worker crash seen after serving first request in Development Environment mode for Rails 2.3.4+ applications.
• Overriding Rack::Deflater to skip response body compression for user-agent Internet Explorer 6.0.
• Renamed 'log' message defined by rb_define_singleton_method() to 'log_message'. This fixes the issue seen when Math.log is called by number_to_human_size() in a Rails Application. It also fixes the worker crash on REE installed with tcmalloc library. (Typically used to result in 404 error for a user trying to access the Admin Panel.) Resolves Tickets #9 and #10.
• Code cleanup in Head, Worker and Helper modules.

WebROaR v0.2.5 gem is now available on Gemcutter. Change log for this release:

• Tested on Mac OS X v10.6 Snow Leopard & Ubuntu 9.10 (64-bit).
• Tested on Ruby Enterprise Edition 1.8.7-2009.10.
• Upgraded rack dependency version to >=1.0.1.
• Upgraded rails dependency version to >=2.3.5. Resolves Ticket #6.
• Redirected 'rake spec' output to STDOUT by default to indicate progress of test execution.
• Implemented exception handling (that works both on ruby 1.8 & 1.9) for handling errors raised in scripts being run by the embedded interpreter in the worker.
• Redirected standard IO right after logger is initialized in worker.
• Handled absolute path for install dependencies. Resolves Ticket #3 - 'Unable to locate gcc on Snow Leopard during installation'.

We pushed WebROaR v0.2.4 gem to Gemcutter last night with the following fixes:

• Fixed intermittent crash issue in head while closing client connections by calling close_connection() directly rather than running it through goodbye_watcher in libebb.
• Renamed on_error callback (introduced by us in libebb) to the more appropriate on_request_parse_error.
• Fixed install issue on ruby 1.9 caused due to invalid multibyte char.
• Fixed the incorrect month value in the file name format for gcore dumps.
• Initialized logging for the worker right as it is instantiated before it connects to the head process.
• Cleaned up wr_wkr_create() method in head/wr_worker.c.
• Print logging level as a string in the log files.
• Fixed invalid pointer being used in 'wr_req_resolve_http_req' function.
• Fixed creation of rack.input stream object. Resolves Ticket #2 related to error seen on posting form with enctype="multipart/form-data".
• Ensured 'starling-starling' gem is used by WebROaR even if 'starling' is present on the system.

We are happy to announce the first public open source release of 'WebROaR - Ruby Application Server'. This product is available for free use under GPL v3.

WebROaR aims to make the deployment of Ruby on Rails™ applications more simple, and provide an integrated solution to monitor the performance of the application and track its exceptions. This is facilitated by a simple and easy to use admin panel of the server.

It also is the best performing server as per "our" benchmarks. We absolutely encourage you to perform your own tests and then arrive at a conclusion. :-)
