Release 2.2.12 -------------- * Improved Bundler support. Previous versions might not be able to correctly load gems bundled by Bundler. * Fixed some Ruby 1.9 tempfile.rb compatibility problems. Release 2.2.11 -------------- * This release fixes a regression that appeared in 2.2.10 which only affects Apache. When under high load, Apache might freeze and stop responding to requests. It is caused by a race conditions which is why it escaped our last release testing. This problem does not affect Nginx; you only have to upgrade if you're using Apache. http://groups.google.com/group/phusion-passenger/t/d5bb2f17c8446ea0 Release 2.2.10 -------------- * Fixed some Bundler compatibility problems. * Fixed some file descriptor passing problems, which previously could lead to mysterious crashes. * Fixed some compilation problems on newer GCC versions. Issue #430. * Support #size method in rack.input. Release 2.2.9 ------------- * Fixed compatibility with Rails 3. Actually, previous Phusion Passenger releases were already compatible with Rails 3, depending on the spawn method that would be invoked. Here's the story: Since Phusion Passenger 2.2.8, when the file config.ru exists, Phusion Passenger will treat the app as a Rack app, not as a Rails app. This is in contrast to earlier versions which gave Rails detection more priority than Rack detection. Phusion Passenger loads Rack apps and Rails apps in different ways. The Rails loader was not compatible with Rails 3, which is what we've fixed in this release. That said, a Rails 3 app would have worked out-of-the-box on Phusion Passenger 2.2.8 as well because Rails 3 apps include a config.ru file by default, causing Phusion Passenger 2.2.8 to use the Rack loader. Earlier versions of Phusion Passenger would just completely bail out because they'd use the Rails loader. That said, with 2.2.9 there are still some caveats: - Smart spawning (the mechanism with which REE's 33% memory reduction is implemented) is *not* supported for Rack apps. This means that if you want to utilize smart spawning with Rails 3, then you should remove your config.ru file. - Rails 3 depends on Rack 1.1.0. You must have Rack 1.1.0 installed as a gem, even if you've bundled it with the gem bundler. This is because Phusion Passenger itself depends on Rack. Both of these caveats are temporary. We have plans to solve both of these properly in the future. * What's up with the Gem Bundler? There has been some reports that Phusion Passenger is not compatible with Yehuda Katz's gem bundler (http://github.com/wycats/bundler). This might have been true for an earlier version of the gem bundler, but the latest version seems to work fine. Please note that you need to insert the following snippet in config/preinitializer.rb, as instructed by the gem bundler's README: require "#{RAILS_ROOT}/vendor/gems/environment" The Rails::Boot monkey patching code as posted at http://yehudakatz.com/2009/11/03/using-the-new-gem-bundler-today/ does not seem to be required anymore. * Fixed support for ActiveRecord subclasses that connect to another database. ActiveRecord subclasses that connect to a database other than the default one did not have their connection correctly cleared after forking. This can result in weird errors along the lines of "Lost connection to MySQL server during query". Issue #429. * [Nginx] Fixed PCRE URL. passenger-install-nginx-module downloads PCRE 7.8 if PCRE is not already installed. However PCRE 7.8 has been removed from their FTP server, so we've updated the URL to point to the latest version, 8.0. Release 2.2.8 ------------- * [Nginx] Fixed some signal handling problems. Restarting Nginx on OS X with SIGHUP can sometimes take a long time or even fail completely. This is because of some signal handling problems, which have now been fixed. * [Nginx] Added OpenSSL as dependency. OpenSSL is required in order to install Nginx, but this was not checked by passenger-install-nginx-module. As a result, passenger-install-nginx-module fails on e.g. out-of-the-box Ubuntu installations until the user manually installs OpenSSL. Issue #422. * [Nginx] Fixed support for internal redirects and subrequests. It is now possible to, for example, point X-Accel-Redirects to Phusion Passenger-served URLs. Patch contributed by W. Andrew Loe III: issue #433. * [Apache] Fixed a GnuTLS compatibility issue. mod_gnutls can cause Phusion Passenger to crash because of an unchecked NULL pointer. This problem has now been fixed: issue #391. * Fixed thread creation issue on Intel Itanium platforms. This fixes issue #427. * Fixed compilation problems on Linux running on the Renesas SH4 CPU. Patch contributed by iwamatsu: issue #428. * The Rack library has been unvendored. The original reason for vendoring was to work around broken Rails applications that explicitly specify Rack as a gem dependency. We've found a better workaround that does not require vendoring Rack. This also fixes a compatibility problem with Rails 3, because Rails 3 depends on a newer Rack version than the one we had vendored. Issue #432. * Fixed compatibility with Ruby 1.9.1 patchlevel >= 152 Ruby 1.9.1 patchlevel >= 152 has a bug in its tempfile library. If you've seen an error message along the lines of *** Exception IOError in Passenger RequestHandler (closed stream) then this is a Ruby bug at work. This bug has been fixed in Ruby 1.9.2, but Ruby 1.9.1 still contains this bug. We've added a workaround so that the bug is not triggered with this Ruby version. Issue #432. Release 2.2.7 ------------- * Removed forgotten debugging code in passenger-install-apache2-module, which caused it not to compile anything. Release 2.2.6 ------------- * Some /tmp cleaner programs such as tmpwatch try to remove subdirectories in /tmp/passenger.xxx after a while because they think those subdirectories are unused. This could cause Phusion Passenger to malfunction, requiring a web server restart. Measures have now been taken to prevent those tmp cleaner programs from removing anything in /tmp/passenger.xxx. Issue #365. * When autodetecting the application type, Rack is now given more priority than Rails. This allows one to drop a config.ru file in a Rails directory and have it detected as a Rack application instead of a Rails application. Patch contributed by Sam Pohlenz: issue #338. * The default socket backlog has been increased from 'SOMAXCONN' (which is 128 on most platforms) to 1024. This should fix most 'helper_server.sock failed: Resource temporarily unavailable' errors. * Fixed compilation problems on Solaris. Issue #369 and issue #379. * Fixed crashes on PowerPC. * Some Ruby 1.9 compatibility fixes. Issue #398. * The installer now displays correct dependency installation instructions for Mandriva Linux. * [Apache] The location of the 'apxs' and 'apr-config' commands can now also be passed to the installer through the --apxs-path and --apr-config-path parameters, in addition to the $APXS2 and $APR_CONFIG environment variables. Issue #3. * [Nginx] Various problems that only occur on 64-bit platforms have been fixed. * [Nginx] The installer now installs Nginx 0.7.64 by default. Release 2.2.5 ------------- * [Apache] Small file uploads are now buffered; fixes potential DoS attack Phusion Passenger buffers large file uploads to temp files so that it doesn't block applications while an upload is in progress, but it sent small uploads directly to the application without buffering it. This could result in a potential DoS attack: the client can send many small, incomplete file uploads to the server, and this would block all application processes until a timeout occurs. In order to solve this problem, Phusion Passenger now buffers small file uploads in memory. Bug #356. * [Apache] Fixed support for mod_rewrite passthrough rules Mod_rewrite passthrough rules were not properly supported because of a bug fix for supporting encoded slashes (%2f) in URLs. Unfortunately, due to bugs/limitations in Apache, we can support either encoded slashes or mod_rewrite passthrough rules, but not both; supporting one will break the other. Support for mod_rewrite passthrough rules is now enabled by default; that is, support for encoded slashes is disabled by default. A new configuration option, "PassengerAllowEncodedSlashes", has been added. Turning this option on will enable support for encoded slashes and disable support for mod_rewrite passthrough rules. Issue #113 and issue #230. * [Apache] Added a configuration option for resolving symlinks in the document root path Phusion Passenger 2.2.0 and higher no longer resolves symlinks in the document root path in order to properly support Capistrano-style directory structures. The exact behavior is documented in the Users Guide, section "How Phusion Passenger detects whether a virtual host is a web application". However, some people relied on the old behavior. A new configuration option, PassengerResolveSymlinksInDocumentRoot, has been added to allow reverting back to the old behavior. Patch contributed by Locaweb (http://www.locaweb.com.br/). * [Apache] mod_env variables are now also passed through CGI environment headers Prior to version 2.2.3, environment variables set by mod_env are passed to the application as CGI environment headers, not through Ruby's ENV variable. In the last release we introduced support for setting ENV environment variables with mod_env, and got rid of the code for setting CGI environment headers. It turns out that some people relied on the old behavior, we so now environment variables set with mod_env are set in both ENV and in the CGI environment. Fixes bug #335. * [Apache] Fixed compilation problems on some Linux systems with older versions of Apache If you used to see compilation errors like this: ext/apache2/Configuration.cpp:554: error: expected primary-expression before '.' token then this version should compile properly. * [Apache] Fixed I/O timeouts for communication with backend processes Got rid of the code for enforcing I/O timeouts when reading from or writing to a backend process. This caused more problems than it solved. * [Nginx] Support for streaming responses (e.g. Comet or HTTP push) Buffering of backend responses is now disabled. This fixes support for streaming responses, something which the Apache version has supported for a while now. One can generate streaming responses in Ruby on Rails like this: render :text => lambda { |response, output| 10_000.times do |i| output.write("hello #{i}!\n") end } * [Nginx] Installer now installs Nginx 0.7.61 by default Previously it installed 0.6.37 by default. * [Nginx] Fixed the installer's --extra-configure-flags flag when combined with --auto-download Arguments passed to --extra-configure-flags were not being passed to the Nginx configure script when --auto-download is given. This has been fixed: bug #349. * [Nginx] Fixed unnecessary download of PCRE The installer now checks whether PCRE is installed in /opt/local (e.g. MacPorts) as well before concluding that it isn't installed and going ahead with downloading PCRE. * Fixed STDERR capturing While spawning an application, Phusion Passenger captures any output written to STDERR so that it can show them later if the application failed to start. This turns out to be much more difficult than expected, with all kinds of corner cases that can mess up this feature. For example, if the Rails log file is not writable, then this can cause Rails to crash with a bizarre and unhelpful error message whenever it tries to write to STDERR: /!\ FAILSAFE /!\ Thu Aug 20 14:58:39 +1000 2009 Status: 500 Internal Server Error undefined method `[]' for nil:NilClass Some applications reopen STDERR to a log file. This didn't work. Of all of these problems have been fixed now. (Bug #332) * Fixed some bugs in application sources preloading Rails >= 2.2 already preloads the application sources, in which case Phusion Passenger wasn't supposed to perform it's own preloading, but the Rails >= 2.2 detection code was bugged. This has been fixed. Rails < 2.2 doesn't preload the application sources by itself, but there should be a certain order with which the sources are preloaded, otherwise preloading could fail in some applications. We now enforce a specific load order: first models, then controllers, then helpers. Bug #359. * Fixed a few bugs in WSGI compliance PATH_INFO is supposed to be set to the request URI, but without the query string and without the base URI. This has been fixed: bug #360. * Fixed some Ruby 1.9-specific crashes caused by encoding issues. Bug #354. * Fixed loading of config/environment.rb on Ruby 1.9.2, because Ruby 1.9.2 no longer has "." in the default load path. Patch by metaljastix, issue #368. * The Users Guide for Apache now mentions something about correct permissions for application directories. * Fixed compilation problems on IA-64 (bug #118). We also reduced the stack sizes for the threads by half, so Phusion Passenger should use even less virtual memory now. * Fixed compilation problems on Linux systems with ARM CPU. * Fixed a few compatibility problems with 64-bit OpenBSD. * Fixed a few typos and minor bugs.
