Sorry, I missed that. That's fine - but what's the difference between that and a finished 'release'?

No I added something to the diagram (included in last e-mail) 'maintenance':

I think that rhombus right in the middle (and the associated comment) with the faded arrows is a very important thing to take on board (for me anyway) - we make the changes in the appropriate branch and merge them back to develop (when appropriate), rather than what seemed to happen in SVN - we often worked in trunk and then copied the 'working' file into the v2 branch...

>> In that, I think, git will help us more than SVN was.

>> For example, for hotfixes, we should REALLY try to refrain ourselves as much as possible. But suppose we have a mechanism in place on what warrants a hotfix, then we could do it as follows ( suggested by http://nvie.com/posts/a-successful-git-branching-model/):
>>
>> Whenever we identify a bug that needs to go in the latest release:
>> 1. Create a branch of master called hotfix (with a nr, or minor version number) 2. Test, merge back into master (set tag on this fix, it will cause git describe to give us a good text for version.txt, and it is marked as a release in github) 3. merge into develop 4. NO MORE work on the hotfix branch, create a new branch for the next one.
>>
>> Then when we're ready to release (also as suggested by the same workflow) 1. Create a release branch, say 2.5 2. Test and fix, and once ready merge into master (set tag on this fix, it will cause git describe to give us a good text for version .txt, and it is marked as a release in github) 3. merge into develop 4. No more work on the release branch, create a new branch for the next one.
>>
>> The master would be the source of the stable release in the future, so from the next release master will be used for the stable release (what is now 2.0) Develop will be the source of the unstable (so it must not be too unstable, really new developments take place on feature branches) When we have an active release branch, there will be an extra zip for the release candidate.
>>
>> The only drawback so far is that if a release has so many new

>> to go to for example php 5.4, or something similar)
>>
>> We can solve that by branching of master right before the release branch is merged into master and merge hotfixes in there as well (for as long as we deem necessary).
>>
>> So the full workflow will be active after the next release (because master currently, is not released). And you could treat the current 2.0 as a maintenance release now. The merging of hotfixes might be a bit more difficult to the maintenance release, but at least it's better than copying!

>> The way that I see it we should be doing everyday development in the develop branch; I've merged Nikodems changes to Master back into develop (SourceTree wouldn't let me commit to develop while Master was 2 ahead!!). As Julian said in an earlier email, I will either do this directly for a single change or a gitflow branch off of develop for larger changes...
>>
>> Not really sure how the releases and hotfixes should work though...
>>
>> I think the thing we have to take most care with (which we didn't always do on Google) was the copying of files between branches/releases. Develop files will often have 'new features' with code that might be unstable. on Google SVN there were a few situations where bugfix changes were being made to the latest revision and then the latest revision file(s) in question were just copied straight over to the v2 branch, introducing any new features into an old release. This is the thing that worries me most, especially if we are having 'Stable' zips built straight from these branches... not really sure yet though how we mitigate this although you can mark chunks in SourceTree and only push those over...

We need to have some discussion about workflow, and I want to suggest gitflow as a good workflow to adopt. Information can be found here http://nvie.com/posts/a-successful-git-branching-model/ and elsewhere (here: https://www.atlassian.com/git/workflows for example).

>>

>> Using Tickets for Issues and New Features:

>>
>> - Using those tickets as a way of grouping work into sprints towards a new release;
>>
>> - Could be trac, could be github, open to suggestions;
>>
>> A better means of testing the software rather than the hit and hope method we currently employ:
>>
>> - Open to suggestions here?
>>
>> - Probably starts with a list of manual tests to work through?
>>
>> - Possibly includes automation (Selenium?)
>>
>> - UnitTesting probably a very long term goal, might not even be possible?
>>
>> So my vision would be that we log tickets, we use that list of tickets as a big to-do list; we create a smaller current to-do list from it for the next release; we do the development a la gitflow; changes get pushed to develop and tested; new version released. It sounds good in theory at any rate, it will require a bit more discipline amongst us, but I think the benefits are worth it. I'd very much appreciate your views...
