Project references v NuGet dependencies - reference

I am in the process of introducing NuGet into our software dev process, both for external binaries (eg Moq, NUnit) and for internal library projects containing shared functionality.
TeamCity is producing NuGet packages from our internal library projects, and publishing them to a local repository. My modified solution files use the local repository for accessing the NuGet packages.
Consider the following source code solutions:
Company.Interfaces.sln builds Company.Interfaces.1.2.3.7654.nupkg.
Company.Common.sln contains a reference to Company.Interfaces via its NuGet package, and builds Company.Common.1.1.1.7655.nupkg, with Company.Interfaces.1.2.3.7654 included as a dependency.
The Company.DataAccess.sln uses the Company.Common nupkg to add
Company.Interfaces and Company.Common as references. It builds
Company.DataAccess.1.0.8.7660.nupkg, including Company.Common.1.1.1.7655 as a dependent component.
Company.Product.A is a website solution that contains references to all three library projects (added by selecting the
Company.DataAccess NuGet package).
Questions:
If there is a source code change to Company.Interfaces, do I always need to renumber and rebuild the intermediate packages (Company.Common and Company.DataAccess) and update the packages in Company.Product.A?
Or does that depend on whether the source code change was
a bug fix, or
a new feature, or
a breaking change?
In reality, I have 8 levels of dependent library packages. Is there tooling support for updating an entire tree of packages, should that be necessary?
I know about Semantic Versioning.
We are using VS2012, C#4.0, TeamCity 7.1.5.

It is a good idea to update everything on each check-in, in order to test it early.
What you're describing can be easily managed using artifact dependencies (http://confluence.jetbrains.com/display/TCD7/Artifact+Dependencies) and "Finish Build" build triggers (or even solely "Nuget Dependency Trigger").

We wrote our own build configuration on the base project (would be Company.Interfaces.sln in this case) which builds and updates the whole tree in one go. It checks in updated packages.config files and .nuspec files along the way. I can't say how much of a time-saver this ended up being for us, even if it might sound like overkill at the beginning.
One thing to watch out for: the script we wrote checks in the files even if the chain fails somewhere in between, to give us the chance of fixing it on our local machine, check in the fix and restart the publishing.

Packages that are not updated when running meteor

I alter some code in a package at
C:\Users\usr\AppData\Local\.meteor\packages\accounts-ui-unstyled\1.3.0\web.browser\login_buttons.js
The thing is , after I alter the code and run “meteor” in the command line the changes are not implemented, I even deleted the whole package mentioned before and run the app and it was like … nothing happened, it’s like the application have some sort of a cache of the packages that he doesn’t have to go to that path to get them , instead it uses what it had from it before.
Can anyone please explain this to me ? What’s happening here ?
The correct way of "changing" a package is to git clone the package from git (or otherwise retrieve it's source) into either a project internal /packages folder or a project external folder (requires environment variable METOER_PACKAGE_DIRS).
If the package is, as in your case, a Meteor internal package, you can also copy only the package into your project and even add it to your versioning.
In this package you then apply your changes. It will be used in favor of the atmosphere package.
A good practice is to also increment the package version, so it is known for everyone that a custom version is in use.
Why you should not change packages inside the users \Users\...\.meteor installation packages folder?
This is the path to packages, that will be used as defaults for every new meteor project you create. Deep changes can create deep damage to your projects since changing a package will apply to all dependent projects.
Think also about project specific customization. The above described method will allow this, too.

should you publish your flow-typed folder to NPM?

I'm wondering if and under what conditions you should publish your flow-typed folder to NPM in your packages. Perhaps (and what I've been thinking) the answer is never, and it's up to application developers to use flow-typed themselves, but perhaps flow-typed install only picks up definitions for dependencies they have declared themselves, rather than dependencies within packages.
So in short, if your package has non-peer flow-typed dependencies, should I be publishing my flow-typed folder or I should I npmignore it?
You should never publish this folder. I don't think anything bad will happen if you do publish it, besides just unnecessarily increasing your package size. But nothing good will happen either.
The point of flow-typed is that if you use those library definitions, Flow does not have to check the library code. Instead, it takes the library definitions as given. If I consume your library, Flow in my project is not type checking your library. Therefore, it does not need to know anything about your dependencies.
Of course, this hinges upon you publishing your library interface to flow-typed as well. Unfortunately, the tools do not yet exist to make this easy, but it is the correct thing to do. If you just publish your source to npm, clients may be using a different version of Flow than you used, and so they may see unactionable error messages that are simply due to version differences (since nearly every Flow release is a breaking change). You may also have different .flowconfig options which could result in errors even if the Flow version matches.

GitVersion – selective versioning multiple assemblies of the same project

I’m on a .net c# project composed by a solution with several class library projects.
The source control is managed by git using gitflow as branching model.
We have decided that we wanted to implement semantic versioning (http://semver.org/) of the project in order to follow a standard way to communicate our releases.
For that we are using GitVersionTask (via NuGet) which works pretty well with gitflow.
Every time we tag a release and we perform a build from the master branch the version of all assemblies are updated and a new release is out for delivery.
Only one of the assemblies has a public API, all the other are for internal consume. I would like to know if this is the correct way to manage the version of multiple assemblies of the same project I mean, isn’t it wrong to change the version of every assembly when only a couple (or even just one) was changed? To get thinks more complicated there is strong possibility that some of the “internal” assemblies will be used by other projects so I believe it not very wise to increment a major version of an assembly that didn’t suffer a change just because another assembly of the same project is promoting breaking changes. Should each assembly project be managed on its own repository?
Thanks in advance.
I know this is a bit of an old question, still:
I want to share a workaround that seems to be working:
GitVersion uses $(Build.SourcesDirectory) to see where the sources are located - src
We can change this using logging commands*
Workaround is to set the Build.SourcesDirectory before GitVersion task
Then gitVersion uses the GitVersion.yml from the project folder (Build.SourceDirectory) and voila - works
After that you might want to roll back the change or not - depending on your need. For me it seems it is nice to scope down to the only nuget package from the collection of nuget packages in our nugetPackages monorepo.
see GitVersion issue and comment
*Example Powershell command:
standard PowerShell task; set to inline script;
Write-Host "##vso[task.setvariable variable=Build_SourcesDirectory;]$(Build.SourcesDirectory)\$(NugetProjectName)"
There is certainly nothing in GitVersion that would help with having separate projects within the same repository. The guidance that we would offer here is that you should use different repositories for the different parts of your application. That way they can be versioned/updated at their own cadence.

Does the case for not including Node modules in version control also apply to Composer packages?

In doing research on whether Node's node_modules should be checked into your version control repository, the most recent consensus seems to be that you should include it for applications you deploy.
Sources:
Check in node_modules vs. shrinkwrap
Should I check in node_modules to git when creating a node.js app on Heroku?
https://www.npmjs.org/doc/misc/npm-faq.html#Should-I-check-my-node_modules-folder-into-git
In reading these arguments, it lead me to question whether Composer's /vendors directory should also be checked into version control. Composer's documentation suggests that you don't:
Should I commit the dependencies in my vendor directory?
The general recommendation is no. The vendor directory [...] should be added to .gitignore/svn:ignore/etc.
The best practice is to then have all the developers use Composer to install the dependencies. Similarly, the build server, CI, deployment tools etc should be adapted to run Composer as part of their project bootstrapping.
While it can be tempting to commit it in some environment, it leads to a few problems:
Large VCS repository size and diffs when you update code.
Duplication of the history of all your dependencies in your own VCS.
[...]
Contrasting that argument is this one (source):
Doesn’t checking in node_modules create a lot of noise in the source tree that isn’t related to my app?
No, you’re wrong, this code is used by your app, it’s part of your app, pretending it’s not will get you in to trouble. You depend on other people’s code and they are just as likely to write new bugs as you are, probably more so. Checking all of that code in to source control gives you a way to audit every line that ever changed in your application. It allows you to use $ git bisect locally and be ensured that it’s the same as in production and that every machine in production is identical. No more tracking down unknown changes in dependencies, all the changes, in every line, are viewable in source control.
In summary, the question is this: Why would one gitignore (i.e. not version control) node_modules but not do the same for Composer's vendor/ directory?
The reason to commit external dependencies is
it's easier to deploy with git pull
the code used is directly included in the commit anyone checks out
Arguments against this are
Git is no deployment tool
all dependency managers do have a way to make exactly sure the code used can be fetched
I don't know anything about npm, but for Composer that last point is implemented by committing composer.lock.
I don't think the "audit code" argument is a valid one in every case. If you do write software that get's audited by itself, and subsequently needs all libraries to be audited, then probably all code changes need to be conserved. This isn't true for the general case.
git bisect works still as well with a committed composer.lock. It does require installing the dependencies with every bisect step, but this is just one simple step, probably already done in the automatic test suite run.
The last thing to worry about is when used packages go offline. This really is more of a problem with Composer, because there is no central hosting of the downloadable releases (npm probably does this). If this is a problem, either commit the code (and try to figure out how to update that missing package in the future), or setup an instance of Satis to create a local copy of the code you use.
Putting all your modules in you VCS makes it really heavy to download or upload. For example, I work on two node.js projects and the total node_modules directories size is between 250MB and 500MB whereas the whole code with assets is generally less than 40MB. Every Node.js developer likes Node lightness, so the code must stay easy to download and share.
For the second point, an alternative to avoid regressions is to be more restrictive in your package.json dependencies versions. You will find more information here.
Finally the best argument is to take a look on the famous modules everybody know :
express ignores
node_modules
mocha ignores
node_modules
q ignores node_modules
...
The more I research this the more I'm starting to think that there is no one correct answer to this, just different opinions as well as pros and cons of each method.
This blog, looking from the context of Bower, does a good job of weighing the pros and cons of each: http://addyosmani.com/blog/checking-in-front-end-dependencies/.
In short: At least for right now, weigh the pros and cons and decide what best fits your situation.

Cruisecontrol.net dependencies

I have a question about dependencies in CCNET. I have several projects, each of them are dependant on another project (a control library as it is referred to internally). When the control library project is changed, and triggers a recompile, how do I get the other dependent projects to be rebuilt?
By using project triggers.
We also have many interdependent projects too, which we solve by telling MSBuild to build a solution file which contains all the projects requires, and in the appropriate build order.
