Recently I''ve found out some mentions to the "--sandbox" parameter to the "rails console" command. And I found the idea interesting, but since I''m using Sequel instead of ActiveRecord I guessed this wouldn''t work for me. But after talking about this subject in the Sequel mailing list, Jeremy Evans has brought to my attention that there are some

For testing, I use: self.use_transactional_fixtures = true This should cause a ROLLBACK for each test case. If I run a single file, foo_controller_test.rb, it works as expected. I see BEGIN and ROLLBACK 8 times in the log files. But if I run: rake test:functionals I get 3 COMMITs, 196 BEGINS and 193 ROLLBACKs. The code in fixtures.rb that deals with this is : def

Hello! I experienced problems with testing transactions which are supposed to be rolled back, but are not, because of transactional fixtures eliminating the inner transaction. Can this be worked around somehow without turning off transactional fixtures? Maybe savepoints can help this? Does anyone have any experience with savepoints to achieve nested transaction functionality? Both Postgres

Quartz has a QuartzDiskTable class which is a thin wrapper for a pair of Btree objects (or just one if the table is opened readonly): http://www.xapian.org/docs/sourcedoc/html/classQuartzDiskTable.html There's also a QuartzBufferedTable class which adds memory buffering of changes to this: http://www.xapian.org/docs/sourcedoc/html/classQuartzBufferedTable.html However, as of 0.8.0 we now

Hi, by switching to MySQL from SQLite, it fixed the problem. I ran rdebug on it and it is trying to call I ActiveRecord::Base.connection.begin_db_transaction. from ActiveRecordSafetyListener.scenario_started. I don''t think SQLLite likes transactions.

I'm trying to compact (or at least merge) multiple databases, while stripping search records which are no longer required. Backstory: I've inherited the Cyrus IMAPd xapian-based search code from Greg Banks when he left Opera. One of the unfinished parts was removing expunged emails from the search database. We moved from having a single search database to supporting multiple

I know ActiveRecord doesn''t support composite primary keys, but I need to use one, and I need it ASAP. I don''t need any composite foreign keys, luckily; what I have is a table that stores old versions of rows in another table, so the composite key is an id + date stamp. Would someone tell me a hack I can use to support this? -- View this message in context:

How do I get ''save'' to execute without commit? I have tried: ActiveRecord::Base.connection.begin_db_transaction # do some stuff that doesn''t issue a database COMMIT statement # then: @myObject.save # this issues a COMMIT but it shouldn''t! Shouldn''t it wait until I''ve called: ActiveRecord::Base.connection.commit_db_transaction ? what am

Hi all - I know this must be really easy to do, but I can''t for the life of me figure it out. I have about 100,000 rows I need to migrate over into rails using a migration. Right now, I select all of them out of the old database and do a series of: ... new.col = old.col ... new.save ... Problem is each one is it''s own transaction. And it''s slow. I''d

After reading all the problems with the x86-64 update, I'm in a quandry as to update this machine or not. Nothing that I am aware of is broken, and at least everything I use works. This is NOT a production machine, but it does have some important software that needs to run twice daily, and I sure don't want to break things for that. If upgrade is not necessary, how do I go about

Hi Today I got an alert mail from my watcher script, telling me that there was no Mongrel running, and that it started one (so the site was down for a few seconds.) This is the first time I got this error (AFAICS), but I''d like to resolve and prevent it for the future. From mongrel.log: ** Starting Mongrel listening at 0.0.0.0:foo ** Starting Rails with production environment... **

I''ve been editing a rails app on Windows for a little while now. I just checked it into source control and started editing on my iMac. Everything seems to run normally, except that when I attempt to modify the database in any way (I''m running sqlite), I get a weird error: "cannot start a transaction within a transaction"

I''m trying to call save in active record after calling begin_db_transaction. In the code I see no place where it calls commit between create_or_update and the end of save. However in the log I see a commit happen...and I don''t want commit to be called does anyone know how to turn this off? thanks brian

Hey all, I've got a couple servers using Maildir format. As I understand it from a simple perspective, 'new' contains newly delivered messages, and 'cur' contains messages that have been 'handled'. I like to keep things simple for users, so rather than have 'Spam', 'Junk' 'ToLearn' and other possibly confusing folders, what I thought I would

Hello, is there a way to optimize sorting by certain values for queries which return a huge amount of results? For example, I just want a simple query that gives me the 200 most recent emails out of millions. The elapsed time for get_mset increases as the number of documents ($n * 2000) increases. I suppose I could store a pre-sorted set using SQLite or similar. Thanks in advance for any

Hi folks.. just a few weeks ago I wrote this to someone else: ------------------------ We have several 2900s in production as VoIP servers.. no lockups. On every server I go into the BIOS and: * Disable USB * Disabled uneeded things like Parallel, Serial * Put ETH0 on a seperate IRQ from the Digium card And everything's fine. Dell's do NOT have to share IRQs... go into your BIOS and

We have an interesting quandry here.

Hi everyone, As I've mentioned before we are doing some work on the LLVM scheduler to improve it. Specifically, we are working to get loads and stores to move past each other when possible. When I asked about enhancing scheduler heuristics a month or so ago, I got a response about a MachineInstr scheduler and that that was the way of the LLVM future. Is that so? Is the ScheduleDAG going
