Transaction rollback on Spring JDBC tests

时光毁灭记忆、已成空白 提交于 2019-12-05 01:25:13
I'm trying to get JDBC transaction rollback when using Spring-test without success. When I run the following the SQL update is always committed. package my.dao.impl; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.annotation.Rollback; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.TestExecutionListeners; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import org.springframework.test.context.support

Cloning a previous version on Heroku

大兔子大兔子 提交于 2019-12-04 20:15:06
问题 I'm new to Heroku. After pushing bad code to the server, I used heroku rollback to revert to a previous version. I then tried to clone this rollback to my computer with: git clone git@heroku.com:<project>.git <dir> Unfortunately, this clones the corrupted head, not the rollback. Is there a way to actually clone a specific previous version? 回答1: When you do rollbacks, the head of your Heroku Git repo will no longer reflect the running state of you app. Check your releases: $ heroku releases

妖精的绣舞 提交于 2019-12-04 13:16:18
问题 I'm trying to write a functional test for my project in Symfony2. I'd like to test if a user can access a page, fill up a form and submit it. I'm tryingto find a way to rollback the database to the state it was before the test. I found a helper class I slighty modified at https://gist.github.com/Vp3n/5472509 wich extends WebTestCase and overload setUp and tearDown methods. Here are the mods I did in order to try to make it works: /** * Before each test we start a new transaction * everything

How to check if Dotnet transaction is rolled back?

对着背影说爱祢 提交于 2019-12-04 09:47:02
How Can I check if a dotnet transaction is closed or not ? using(TransactionScope scope = new TransactionScope(TransactionScopeOption.RequiresNew)){ try{ //Do something; scope.Complete(); //denotes the transaction completed successful. } catch(TransactionAbortedException ex) { //scope.Complete(); is never called, the transaction rolls back automatically. } catch(ApplicationException ex) { } } Your title asks one thing and your question asks another. so, I am going with your title.

How to discard all changes made to a branch?

泄露秘密 提交于 2019-12-04 07:21:34
问题 I'm working in a branch (i.e. design ) and I've made a number of changes, but I need to discard them all and reset it to match the repository version. I thought git checkout design would do it, but it just tells me I'm already in branch design and that I have 3 modified files. How would I discard those changes and get the branch as it stands now on the remote server? 回答1: Note: You CANNOT UNDO this. Try git checkout -f this will discard any local changes which are not committed in ALL

Transactional DDL workflow for MySQL

夙愿已清 提交于 2019-12-04 00:49:41
I was a little surprised to discover that DDL statements ( alter table , create index etc) implicitly commit the current transaction in MySQL. Coming from MS SQL Server, the ability to do database alterations in a transaction locally (that was then rolled back) was an important part of my workflow. For continuous integration, the rollback was used if the migration hiccuped for any reason, so that at least we did not leave the database in a half-migrated state. How do people solve these two problems when using MySQL with migrations and continuous integration? DDL statements cause an implicit

How to detect a rollback in MySQL stored procedure?

半城伤御伤魂 提交于 2019-12-03 20:18:13
I'm trying to figure out a way to detect an occurrence of rollback in a MySQL stored procedure so I could handle the situation accordingly from a PHP script, but so far I can not find any solution. My stored procedure looks like this: delimiter | create procedure multi_inserts( IN var1 int(11), . . . IN string1 text ) BEGIN declare exit handler for sqlexception rollback; declare exit handler for sqlwarning rollback; START TRANSACTION; insert into table1(a,b,c,d) values(var1,var2,var3,var4); insert into table2(e,f,g) values(var5,var6,string1); COMMIT; END delimiter ; I did a rollback test on

Why are transactions not rolling back when using SpringJUnit4ClassRunner/MySQL/Spring/Hibernate

橙三吉。 提交于 2019-12-03 13:55:41
问题 I am doing unit testing and I expect that all data committed to the MySQL database will be rolled back... but this isn't the case. The data is being committed, even though my log was showing that the rollback was happening. I've been wrestling with this for a couple days so my setup has changed quite a bit, here's my current setup. LoginDAOTest.java: @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations={"file:web/WEB-INF/applicationContext-test.xml", "file:web/WEB-INF

JMS rollback

老子叫甜甜 提交于 2019-12-03 12:46:48
I have a process which involves sending a JMS message. The process is part of a transaction. If a later part of the transaction fails, a part that is after a previous part that sent the message, I need to cancel the message. One thought I had was to somehow set on the message that it is not to be picked up for a certain amount of time, and if I need to rollback, then I could go and cancel the message. Not knowing messaging, I do not know if the idea is possible. Or, is there a better idea? Thanks You can use JMS and JTA (Java Transaction API) together - see here . When doing that, the sending
