Well, for that particular item, I can visit any of my local supermarkets for the 3% stuff or I can go to a hydroponics shop for the 50% stuff. $3.something for 250ml at the marketsuper and about $13 for 500ml of 50% at the hydro shop. I can't buy the stuff online, since no-one will ship the strong stuff. (and yes, that is 3% and 50% - not 3vol and 50vol)
Some of my favourite music has been bought second-hand complete with cover-art and a real disc at local-shops. Same with movies/docos.
That said - I bought an adjustable Grobet jeweller's saw-frame at a local shop about 15 years ago for AUD $50. Having misplaced it a number of years ago I recently sought to replace it. I ended-up buying one from Amazon for about $23 delivered to my door.
Like any kind of shopping, the best place for purchase seems to depend on the item and the time its wanted. 100gm, 0.01gm resolution digital scales for AUD $80 locally or about $10 from flea-bay - simply no comparison!

Hello All,
We are in the process of reviewing our source control and the way we integrate.
Currently we are using SVN but not using it's merging feature etc. All the basic ones like getting latest, commit, put etc.
But our team has now increased and quite often two developers end up over writing each others code. Our environment looks like -
Test server - where development happens and sit till the functionality is approved
Live server - Once functionality is approved and tested, it goes to live (production) server.
So my questions are:
1. What do you recommend - svn or GIT or svn is completely fine as long as we use all the features.
2. Should we really be developing in local and then pushing to test server and then production or what do you recommend?
3. Any other tips to automate this process?
Thanks

Why it doesn't make sense? You should be smart enough to understand the text. If you aren't that smart then not sure what exactly are you doing here  ..

How uncoordinated does someone have to work that it is possible to overwrite someone else's code when using a tool like SVN?
Never heard of LOCKS or the possibility to communicate with each other to prevent such things?
That is what makes no sense, but since you seem to be clever i guess you already knew that right?

Yes, I very much know about locks but you can only lock it at SVN level not server level. Right? If tom, dick and harry lock few files then I can still push the file to test server and to production after making changes to it? So it doesn't help.

That's what we are doing now which takes up lot of time. So need a better solution.
Hope you got my point smarty pants?

You may be using SVN, but you aren't using it correctly. This isn't a software problem.
Here's a super quick, overly simple view of what should be going on:
Daily work
=================
1) Check out code
2) Modify Code
3) Developer level / Unit testing
4) Check in code (handle your merge issues)
Build
=================
1) Checkout code
2) Tag or version the checked out code
3) Build the code
4) Test the code
A) If test successful, push to production
B) If test not successful, dump the build.
Notice that there is no modification in the build process?

Without going through a build/test/QA phase? That's nuts! This is a process problem, not a source control problem!

That sounds more like a merge management issue.
Sometimes you have to merge changes manually if more than one person is working on the same library or the same source code file.

Yes it is sort of that. Here is the scenario that explains it better - ]
Dev A gets latest code from the sub version control
Dev A is happy that he got the latest files and start working on file A, B, C, D
Dev A pushes the code to test server and wait for approval for couple of days.
Now Dev B needs to work on files B, C. A very quick 2 minute job.
He does the same, gets latest code from the sub version control
Deb B is now happy that he has got the latest files and start editing it.
But he is not aware that there is another newer version waiting to be approved on a test server
Dev B finishes the edit very quickly and push the code to test server. and TEST SITE BREAKS!! Or it might just work if changes to the other files are not dependent.
Now after a weeks time, dev A gets an approval to make the functionality live. He goes back to the test server and all the changes are now lost. He pulls his hair and cry Why Why Why ME? If he is lucky, he may have a local copy which he can push to the test server again but then it’s time for Dev B to cry as his changes will be lost.
May be we need to make a good use of branches. And also pushing code to test/production is all manual at the minute. Which is basically an overhead.

This sounds more like a workflow issue that svn (nor git or mercurial, for that matter) can completely. If anyone can deploy to test at any time and potentially blow away someone else's changes, you're going to run into issues. What would help would be for developers to do something like create a git branch fro whatever feature they're working on. That way, at least they'll still have a local copy of whatever they were working on in case someone else overwrites it on the test server. Git branches are cheap. Even with svn, though, there's not much excuse for losing changes because you pushed them to a remote server and then got rid of your local copy.
Perhaps begin with a policy that developers can never, ever, push something straight to the test or production server.
Set up a CI server like TeamCity that will run your build and run all tests whenever someone checks code in. Set up TeamCity to automatically deploy to the test server once a week (or whatever time interval works best for your team). Make sure all developers know when this happens, so they'll be able to commit/push their changes in time. Create a tag or branch in source control representing the build that has been pushed to the test server.
Once the build on the test server has been running well enough on the test server and you're ready to deploy it to production, grab the correct version from source control (easy since you have a branch or tag for it) and deploy it to production.

The simple answer here, I think, is to check in your code when you change it, and not after it has been through the test server process. If it fails testing, you need to fix it, check changes in then submit to test server - so everyone is getting the latest version of the source most of the time, rather than having long delays between getting code and updating.
though I'm not sure what you mean by 'test server' in your context - are you pushing code to the test server before checking it back in to SVN?

Basically, we get latest from the svn and then dev A works on it and pushes to test server directly and not to SVN. Once bugs are sorted and is a stable version, then dev pushes it to SVN and to production server.
I am going through all the suggestions now and see what can work for us.
Thanks

Get them to pay for a consultant for a couple of weeks. I've recommended this at a couple of gigs and it worked really well (TFS). It was well documented as a bonus so well worth the outlay.

SVN is not a substitute for brain or basic human decency. It simply wasn't designed for that.
it ain’t broke, it doesn’t have enough features yet.

Anyway, what I would do is, make some rules:
- every class - separate file
- class with more then 10 methods - refactor
- methods with more that 30 lines of code - refactor
- assign them to work on separate tasks and commit/merge at the end of every day in a test repository.
- Production version code in a separate repository
it ain’t broke, it doesn’t have enough features yet.

I can't speak to GIT. I haven't used it other than playing around. But we do use SVN. I have tried to keep the developers from working on the same code and that has worked pretty well. The one big problem we have is with the dbml files for Linq. And really what is required is communication between developers. It is almost impossible to manage changes through SVN. We normally revert then make the changes then commit. It can be a pain when more than two have modified the dbml.
As long as they are talking and they stay out of each others code, which is easier said than done, SVN is working really well for us without all the extra features.
We are using both TortoiseSVN and AnhkSVN. AnhkSVN has some issues with updating the code when there are conflicts but TortoiseSVN works great.
Jack of all trades, master of none, though often times better than master of one.

We are a team of almost 100 developers working on the same code. We use git and merge seems to work well in most cases. We do not use a test server because of problems that you describe. Instead we schedule regular 'stability points' that serve as snap shots and used for testing etc. A few days before a stability point, we are asked not to push any major changes while a few team members do some simple testing and fixing before releasing the build for major testing/customers etc. Anything major is then fixed in the stability branch and cherry picked over to the main branch. It is not ideal but it seems to work acceptably especially with so many developers working on the same code base.
Of course, our code is for embedded systems and so it is a little different to what you describe.

Sounds good but where do you test these stability points? At local or development server?
|
|
|
|
|
We make a separate git branch for each stability point and deploy the code to several development benches for testing. One challenge of doing it this way is that some things that are found in a stability point may already be fixed in the master branch and so it takes a little extra time to go through the issues to verify that's the case. It also means that you may end up fixing the issue in both branches but with git, the cherry-picking seems to work quite well.

A couple of years ago I was in exactly that situation, except even worse.
Some projects were in SVN and some even in CVS.
Branching and merging wasn't something you did, if you had something planned for the weekend next month.
So I did some serious research over a longer time and came to the conclusion that what we needed was a distributed version control.
This is for several reasons, but one the main ones is that as you have a local copy you can commit to as often as you want, and step back to earlier versions of the code without affecting other developers.
And then you only push working code to other repos.
Secondly, merging works. Really!
The two leading systems are GIT and Mercurial, and of those two I ended up choosing Mercurial, despite Git having the momentum.
One of my reasons: While Git is more powerful and has more plugins, it is also less homogenous and has a steeper learning curve than Mercurial. Obligatory xkcd reference[^]
And as far as I understand, the main reason Git has the momentum is because Linus Torvalds chose it for Linux, and his main reason was that he could rewrite history using the Rebase plugin that didn't have an equivalent in Mercurial at that time citation needed
But it also requires a change of mindset. When using a DVCS you're really supposed to work with branches. Have a look at Hg Init: a Mercurial tutorial by Joel Spolsky[^] for a really good primer.
Mercurial also integrates really well with SVN, just install the HgSubversion extension and you can keep on using SVN if you'd like, while having a local clone of the repository working with Mercurial.
BTW, the simplest way to use it is to simply install TortoiseHG and integrate it in VS with VisualHg

Git is probably a better tool if you want to branch and merge back easily. SVN can do that too, but the process is a bit more laborious.
However, if your team can master the art of branch/merging then you would be able to set up a dev/test/live branches, which in turn can be split into further sub-branches. e.g. changes associated with a single CR will be branched from dev.
The person responsible for configuration management will manage what specific branches merge onto the main branches. Then the dev master branch is propagated to test and then test to live. Because your developers work on their own branches, they should never need to lose their work again, and if a merge goes badly it should be easier to undo it.
You should also review how your code is structured, both in design and on file. If you have only two developers treading on each other toes it may be a symptom of design issues within your application.

It sounds like you are using your test server as the integration point rather than your source control system.
Source control should be your integration point, and when a new test is desired, push from source control to the test server.
An automated build process (extract from source control, build, push to test server) might help.
It's a fundamental workflow problem.

I think this is the heart of your issue. It's not the tools but how you are using them.
- All changes should be checked in before they go to test.
- Test (and Prod) should be always be built from some specific SVN revision.
- You probably could use a branch for what's in prod where quick fixes can go and another branch or trunk for the next big release. You'd have to merge prod fixes to the release code. And you might want a dev server to "test" the bigger changes on.
Something like that...
