similar to: Transactions with different types of model object

If I want to wrap two account updates, the syntax is ... Account.transaction(dennis, david) do dennis.withdraw(10); david.deposit(10); end .. where both dennis and david are instances of Account. Can someone please let me know what the syntax is for starting and ending a *single* database transactions which spans two *different* kinds of models/tables ? Dennis Byrne -------------- next

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

Hey Xiaoming, Thanks for those source codes. Can you please explain what this llvm-memory-profiling.patch does ?

Hey John, Thank you for the detailed reply. I tried to figure out myself which IR should I use for my purpose ( Clang's Abstract Syntax Tree (AST) or LLVM's SSA Intermediate Representation (IR). ), but couldn't really figure out which one to use. Here is what I m trying to do. Given any C/C++ program (like the one given below), I am trying to insert calls to some function, before and

The patch file is a diff file generated by "svn diff". It is about other modifications such as adding some lines to make files to make the added .c and .cpp files compiled. You may apply the patch file to LLVM source code by using a "patch" command or make the changes manually by reading the patch file. Xiaoming On Wed, Sep 28, 2011 at 6:05 AM, Himanshu Shekhar

How do i manually abort a transaction? Thanks, Chris -- Posted via http://www.ruby-forum.com/.

Hi, Himanshu. I once wrote an LLVM IR-based memory profiling pass. Basically, I followed the code for EdgeProfiling. The source code is enclosed here, which worked with LLVM 2.8. Hope it is helpful. MemoryProfiling.cpp---the instrumentation pass, which inserts profiling function calls into the original program MemoryProfiling.c---the profiling library containing the profiling calls

Hi, I am trying to understand S3 classes. I have read several tutorials about the topics but I am still a bit confused. I guess it is because it is so different from Java OOP. I have pasted my attempt at creating a bank-account class below and my problems are: 1. What should be added some plot.default() calls the account$plot() method ? 2. What should the account$plot() be implemented to

Hi all, Is there any command or function to withdraw a command performed already in R? For instance, after drawing a line in existing plot, can I remove the line in the plot? I know I can use a way of overlapping on the former line so that it looks like a removing the line, but I'm wondering there is a command to retract the already performed command. Thanks.

Hello! I just joined this mailing list, so I apologize in advance if this topic has already been covered. Red Hat and Suse announced they are no longer supporting OpenLDAP in future releases. https://www.ostechnix.com/redhat-and-suse-announced-to- withdraw-support-for-openldap/ However, we mainly use CentOS and while it's a RH derivative, I wanted to find out what CentOS plans on doing in

Hey guys, I have seen your interesting conversion. I am new for LLVM as well as clang compiler. I am going to use it now. it is quite difficult when someone starts it from scratch. But it is enjoyable and it is possible to familiarize with the environment by short time. Am gonna to use clang + llvm to generate AST from source code by using clang and to do high level transformation. Then I want to

Hello, What you're describing is basically the parsing and codegen portions of clang. I'd suggest reading through the code there and posting to clang-dev if you have any specific questions. The clang devs are more likely to see your questions there as not all of them also hang out here. Regards, Jim On Sep 28, 2011, at 8:28 PM, eyasu getahun <eya.get at gmail.com> wrote: >

Great! Thanks everyone for the input, I'm going to start splitting up the patch. I'll send out the non-mechanical parts separately.
