Hi,

I just migrated to Fedora 25, and I encounter a crash of passenger (running a redmine behind an apache). Unfortunately, I don't know nothing about Ruby, Passenger or whatever, so here are the raw logs If you want more information, please ask by sending me a mail.

Hi, thanks for reporting. The crash appears to have happened in C++, in Thread 4:

#0  0x00007fd7bd9ba46d in raise () from /lib64/libpthread.so.0
..
#3  0x0000556b4e4cfd82 in Passenger::ApplicationPool2::Group::createProcessObject(Json::Value const&) ()
#4  0x0000556b4e4d051d in Passenger::ApplicationPool2::Group::initialize() ()

I installed redmine on a clean Fedora 24 and I cannot reproduce your crash.

So we need more information to see what about your system is triggering this.

Note: if you are an Enterprise customer we can provide support by email.

Tcharl commented 7 years ago

Hi OnixGH,

It worked perfectly on F24, I upgraded my system to Fedora 25... I installed passenger with dnf, and the crash always happens.

I'll try to test on a VirtualBox image when I'll have some times, but now it's on my own raw home server.

Regards,

OnixGH commented 7 years ago

I'm not familiar with dnf, but did you try to install using the gem or tarball method?

Either way it would be great if you could reproduce it on a fresh VM.

OnixGH commented 7 years ago

Tried again on Fedora 25 (clean image from DigitalOcean, gem install as the pages I linked to describe), still works without errors or crashing.

jbeima commented 7 years ago

I am seeing this as well.

Under Fedora 24 I had 7 Ruby on Rails apps that ran just fine.

Now that I have upgraded to Fedora 25, I get this from passenger:

jbeima commented 7 years ago

All 7 rails applications worked just fine before I upgraded my Fedora 24 -> 25.

Now not one of them works.

HOWEVER

The Rails console/irb works fine.

There is nothing in the rails logs at all. It is as if passenger never even gets to the point of looked at the Rails app.

jbeima commented 7 years ago

I have even tried creating a new app and the new app does not work either. Same error.

jbeima commented 7 years ago

Just in case this helps, these are the installed rpms with Fedora 25.

Interestingly enough Fedora now longer provides the gem "The Ruby Racer".

@jbeima Thanks for reporting. The raise() in your logs confirms the same crash location.

jbeima commented 7 years ago

@OnixGH

Fedora now has an extremely reliable upgrade process. Pretty much three (four) steps:

01) dnf upgrade --refresh 02) reboot - Optional if kernel was updated 03) dnf system-upgrade download --refresh --releasever=25 04) dnf system-upgrade reboot

This development server started out as Fedora 21 and was upgraded through the above mentioned steps to 22 to 23 to 24 to 25.

In all cases Apache, Passenger, Ruby, and Rails worked just fine, with the exception of the upgrade to 25.

I have ZERO interest in compiling ANYTHING. Whenever possible I have even avoided gems to be able to use RedHat/Fedora provided ones.

You can't have a development environment that freely updates anything at any time.

Plus I have no interest in riddling my servers with devel rpms and srpms.

Passenger crashes on a brand new just created app withnothing yet done to it. Can not even get the "Splash" screen so to speak.

I have not and will not look at source tarballs.

Given this, are you saying that the rpm that is included with Fedora is broken, since if that is the case this should be submitted to the FedoraProject and not here. Unless it is broken because of something your project has done/caused.

jbeima commented 7 years ago

@OnixGH

The above message aside. I have stripped out all version numbers from the gems and allowed the system to install all gems from source via the bundle install command. Nothing.

Please remember in the app.log directory nothing is added to any log file.

Only the Apache general error.log file is written to. It is as if Passenger never even gets to the point of trying to load the app.

Also rails console works just fine, so it is not Ruby, Rails, or the gems.

Honestly gents, I am happy to try anything that does not involve compiling anything.

I have an extremely simply virtual host file:

<VirtualHost 1.2.3.4:80>
   ServerName app-01.domain.com
   ErrorLog logs/app-01.domain.com-error_log
   CustomLog logs/app-01.domain.com-access_log combined
   DocumentRoot /home/rails-devel/development/rails/app-01/public
   PassengerAppRoot /home/rails-devel/development/rails/app-01
   RailsEnv development
   RailsBaseURI /
   <Directory /home/rails-devel/development/rails/app-01/public>
      # Relax Apache security settings
      AllowOverride all
      # MultiViews must be turned off
      Options -MultiViews +FollowSymLinks
      Require all granted
   </Directory>
</VirtualHost>

Same for each of the 7 projects with obvious updates.

I did add the +FollowSymLinks to this setup with Fedora 25, since I have read it is needed, and I never needed it before.

OnixGH commented 7 years ago

@jbeima we're not affiliated with the dnf packages so we can't fix anything there..

Passenger supports such a wide variety of systems and technologies that many times the problem does not actually lie with Passenger. But we're always going out of our way to make sure of that and point our users in the right direction.

That's why I've been asking you (both) how exactly you've installed Passenger so I can see if I can at least reproduce the crash and maybe see what's wrong with the install. I'm still waiting for an answer because a simple dnf install passenger doesn't appear sufficient (it complains about a nonexistent passenger-devel-5.0.30 package when I run passenger -- no idea what that's supposed to be).

Btw. although passenger provides very friendly compilation guidance (it's real easy!), installing Passenger standalone via source tarball should not require any compilation on Fedora (auto-download of compatible precompiled binaries from our servers).

If you crash-test that with one of your apps, we'd have the important clue whether it's related to our Passenger binary or the dnf version.

@OnixGH

I am not prepared to compromise my development platform by riddling it with compilers and source code that are not needed.

NOW given that, I don't mind helping in setting up a test bed. If you have a VPS I can have access to, or I can set a temporary one up.

You should not need the devel rpm, not sure why installing passenger would even ask for it.

devel rpms simply carry the header files. So the .h files. They are only needed when something needs to be compiled referencing Passenger's libraries/headers.

Here are the rpms that you would need and should not require anything else:

httpd-2.4.23-4.fc25.x86_64 httpd-filesystem-2.4.23-4.fc25.noarch httpd-tools-2.4.23-4.fc25.x86_64 http-parser-2.7.1-3.fc25.x86_64 mod_passenger-5.0.30-1.fc25.x86_64 passenger-5.0.30-1.fc25.x86_64

A simple:

dnf install httpd mod_passenger mod_ssl rubygem-rails

Should get you what you need.

I apologise for the delay in the response I have been pulled in several directions today.

Part of this might be done quicker in email.

jbeima commented 7 years ago

By the way your response was correct there is no devel rpm, not sure why Passenger would even need one, I don't think anything compiles against it?

jbeima commented 7 years ago

This could be an important piece of the puzzle?

I am not running Passenger directly, I am running mod_passenger through Apache.

Not sure if that makes any difference to all this or not.

OnixGH commented 7 years ago

@jbeima Installed Passenger 5.0.30 using your commands and reproduced the same crash with the rails helloworld app.

The application works fine on the same server if I point Apache to the Passenger 5.0.30 install as recommended / supported by Phusion.

In conclusion there are two solutions to this issue: 1) Use one of our supported installation methods 2) Fix Fedora package

We can't really do anything about 2), as far as I could see the Apache integration module from the Fedora package was OK, the app still worked if I pointed Apache to the Fedora package mod_passenger.so, but with the self-installed passenger root so the problem is more likely to be in the compiled PassengerAgent they supply.

jbeima commented 7 years ago

I have isolated and confirmed where this bug is.

If you download the source tarball of Passenger from here:

https://www.phusionpassenger.com/latest_stable_tarball

The untar it and do the following:

01) cd passenger-5.0.30 02) ./bin/passenger-install-apache2-module 03) cp buildout/support-binaries/PassengerAgent /usr/lib64/passenger/support-binaries 04) systemnctl restart|start httpd

Passenger then works fine.

This one file is broken. There might be more but this at least brings all of the offline down systems back online.

NOTES: When running passenger-install-apache2-module select only Ruby when your asked about the 4 languages. Unless you want the other 3. Seems pointless for a Rails server. I am unaware of what the default choices are for Fedora.

Tcharl commented 7 years ago

Thank @jbeima ! will create a ticket on fedora issuetracker if there isn't

FooBarWidget commented 7 years ago

@Tcharl If you have created or found a ticket, could you link to that ticket from here? I'm curious about any analysis the packager may have.

@jbeima: In another you thread you said this:

If your already doing a fix compile for Cent & RHEL, why not do a release for Fedora or at least help us to get it fixed.

I understand your frustration. I ask for your understanding w.r.t. our situation as well. We support a ton of different distributions and platforms, and it is very challenging to package for all of them. Since time is a limited resource, we have to carefully balance our time between packaging, maintenance and feature development.

Fedora is a very active target and has (compared to Debian, Ubuntu, CentOS and RHEL) relatively few users. Analysis has shown that, given the resources we have at our disposal, packaging for Fedora and updating these packages on every Fedora release cycle would place too much of a burden on our team for too little gain. If we have unlimited resources, we would have gladly helped you.

The next best things we can offer you are:

  1. A set of source RPMs which you are free to modify for Fedora compatibility.
  2. A tarball which makes use of precompiled generic Linux binaries.
Tcharl commented 7 years ago

Sure, here's the fedora bug: https://bugzilla.redhat.com/show_bug.cgi?id=1403569

OlegGirko commented 7 years ago

Looks like this is still a fault of Passenger to some degree.

Look at this bug and its description.

Of course, it's Fedora's fault that unbundling of jsoncpp went bad. But it's Passenger's fault that it bundled this library in the first place and then patched it incompatible way without upstreaming this patch.

I could understand that you may feel an urge to bundle some essential libraries to make development easier (less dependencies to install). But please resist this temptation.

Remember, that users of your software are not end-users who do make install (or any equivalent of it) on their system. There are people like that, but they are a minority. Real users of your software are packagers that package your software for Linux distributions. This is how your software reaches most end-users.

We (end-users) are not interested in building and installing software from source. What we want is just to install your software with dnf install (or apt-get install or any GUI equivalent), so it not only starts running on our systems, but also is included in automatic update system.

I have hundreds of packages on my Fedora system, and Passenger is just one of them. I don't want to check manually for security patches for all of these packages, so I prefer to trust Fedora packagers to push updates to Fedora package repos and keep my system updated this way. Hence, your recommended way to install Passenger is actually harmful and not recommended because it leads to outdated and vulnerable software installed and never updated.

Returning back to library bundling, all sane Linux distribution try hard to unbundle as much libraries as possible. Bundled libraries lead to not only wasted disk and memory (several packages using the same library), but also security vulnerabilities. If there is a bug found in some library, it's enough to update just the package containing this library to fix this bug in all packages using it. But bundling this library with your software is a way to ensure that the fix will be missed.

You may argue that bundling a library makes life easier for people using systems that have no proper package manager (Windows, MacOS) and where it's difficult to install all dependencies. Then you should provide an easy way to choose whether to build your software with bundled version or with the one provided by the system.

And what you should never ever do is patch bundled library without upstreaming your changes. This makes life more difficult for everybody, including you: you have to either keep your change and rebase it on every new version of library, or stick with old library version forever. And it makes life extremely difficult for packagers who try to unbundle this library.

So, this particular bug is caused by botched attempt to unbundle jsoncpp by Fedora packager, but the root cause is patched bundled library. Never patch bundled libraries. Instead, provide a workaround in your own source code. And make unbundling easy.

HerbertKoelman commented 6 years ago

Does anyone know if this Fedora 25 packaging issue still exists in fedora 26 or higher ?

Tcharl commented 6 years ago

The last time I tried it was always here, 26 and even for 27. The hack consists in manually installing passenger on the machine, without using dnf/yum

HerbertKoelman commented 6 years ago

The hack did indeed do the trick 😊
