similar to: postgres-pr barfs at ActiveRecord::Base.allow_concurrency = true

First of all, I''d like to do what I''ve seen several others here do: thank Ezra and any other contributors for producing a really great plugin. Even though I''m having some minor problems, this is all so approachable and easy to work with and dig into... I hate to think of the hoops you''d need to jump through (both as creator of such a system and as a user) to

Hi, I''m trying to write a new postgresql adapter which interited the old postgres adapter and I try to use the PGconn class, But I find out I can''t access to some of the exported functions in postgres.so (I''m using LINUX) In fact, only the methode export with rb_define_singleton_method can be used, only function s exported with rb_define_method, the PGconn ruby class

I see that allow_concurrency is set to false by default. What are the risks and what can I eventually gain by setting it to true in terms of application speed ?

Hi, I found many references on the Web to the fact that "Rails is not thread-safe". However, I have not found an explanation _why_ it isn''t? What happens if multiple requests are handled concurrently by ActionPack? Assuming that the code I execute in my controller methods is thread safe, is this ok? If not -- what happens? The following makes it sound like the issue is

In a previous email you wrote this: Glad you''re getting some use out of the plugin ;) ActiveRecord does have some issues with threading and concurrency that can sometimes cause that error you are seeing. Open up your script/backgroundrb/ start file and comment out the following line: ActiveRecord::Base.allow_concurrency = true Make sure you do that up in your main app script folder

I''ve installed the postgres-pr gem, and it is found using gem list v0.4.0. In my active record source, inside the postgresql_adapter.rb file, I''ve changed line 7 from: require_library_or_gem ''postgres'' unless self.class.const_defined?(:PGconn) to: require_library_or_gem ''postgres-pr'' unless self.class.const_defined?(:PGconn) ...to try and

Hello all, Are you aware of the rails ActionController::Base.allow_concurrency option ? If this option is true, rails is able to process simultaneous multiples actions. It appears that rails is thread-safe (if the user application is), and that this option is mostly unknown. Webrick take care of this option in rails-1.1.2/lib/webrick_server.rb at line 80 : REQUEST_MUTEX.lock unless

Is there some special magic that needs to be performed so that the C-based postgres extension library works with the Rails console? I have installed the postgres extension library (replacing the pure Ruby version: postgres-pr) from <http://ruby.scripting.ca/postgres/> Everything works great from WEBrick, but as soon as I fire up the console and try to use it, I get a bus error:

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Anyone know what''s going on with ActiveRecord Edge and 1.2RC1 unit tests.

Hi! I want to escape binary data correctly either manually or using some pre-defined function that does this for me! I have found on the web: PGconn.escape_bytea but I only get "undefined method". Any ideas, what is the correct way of doing this my self? I''m using Rails (WEBrick) under Windows XP with postgre-pr 0.4.0 I have tried: s_buffer = s_buffer.gsub(/['']/,

I forgot to take out the portion that would read in the voicemail boxes from the text file. If you want to leave it in then you could have some voicemail boxes defined in the text voicemail.conf. I do not, so I have removed it. Below is the new patch: *** app_voicemail.c 2004-06-23 07:55:54.000000000 -0600 --- app_voicemail.c.new 2004-06-23 07:55:47.000000000 -0600 *************** *** 49,61 ****

Hello all, I am just getting going on building my system, but I thought I'd send you all a patch that I wrote so the command: show voicemail users issued from the CLI works properly when there is a postgres backend for the voicemail. The current version of the app does not display the voicemail boxes found in a database. It is called in the load_config function. I haven't done

I have tried small ruby program like require ''rubygems'' require ''postgres'' db = PGconn.connect(''localhost'', 5432, '''', '''', ''prdjnj'',''postgres'', ''postgres'') res=db.exec("select * from users limit 300000") res.clear puts "After clear result

This is a low priority thing, but X-Lite-4.0 is not out for linux and the windows version barfs, and I'm wondering if anyone can spot what's going wrong. I go through menus, agree to license, accept default install location & click next. Nothing happens. Click next again, and I have the "install" option. That exits prematurely with this: ~~~~~~~~~~~~~~~~~~ bash-4.1$ wine

Hi, In the quest for better test cases for my MP, I thought of trying the Stepanov Abstraction Penalty benchmark. But apparently llvm-g++ is not ready for such terrible things.

Greetings: I tried to install M$ Encarta over my internal network onto my kids' Windoze 2K machine tonight; the Encarta install stuff is in a vfat partition on the Samba server. The install started, then quit about 14% of the way through - the connection to the Samba server apparently was lost - the installer began complaining about being unable to find the CD-ROM, and I was unable to browse

We've been having trouble with OpenSSH 2.9p2, running on Solaris 8 (a domain of an E10k), with PAM authentication turned on. It intermittently crashes with signal 11 (seg fault) after the password is entered, after the MOTD is displayed, but before control is passed over to the login shell. I eventually managed to persuade sshd's child process to consistently crash, upon entry of an

I have been running R CMD check for the first time on of our own packages, which otherwise builds, installs and runs just fine. The package depends on package akima and suggests package multtest; suggesting multtest is indicated because a) it loads a lot of other Bioconductor packages, very slowly, and b) it is only needed for one specific subroutine, which executes require(multtest)
