How to prevent Trac to show some commits in the Timeline? - trac

I'm trying to configure a trac server we are using in my team, in order to avoid an undesired behaviour. We are mainly developing free and open-source software in the team, but we sometimes need to be able to build our early prototypes as completely private.
Because of our first constraint, we want our timeline to be visible for anonymous users. But because of the seconde constraints, we want some commits to be completely hidden from the external world, i.e. we don't want anybody else than us to be able to read the message and content of some commits in the timeline.
Unfortunately, I've been unable to configure Trac the proper way to reach this behaviour untli now. I wan't find a configuration that would let me manage the Timeline content with enough accuracy.
Consequently, I would like to know if such a configuration is possible with trac.
For information, I'm using Trac 0.12.2. The installed plugins are :
Trac 0.12.2
TracAccountManager 0.2.1dev-r7731
TracNav 4.1
The only permission I can see that is related to Timeline is TIMELINE_VIEW.
EDIT :
I have forgot to mention something. We don't want to loose the private commits. And we want them to display for registered users. Consequently, it's not a solution for us to remove them from the database.
EDIT 2 :
Ideally, we would like the commits' message to be displayed according to the right to read the content of our Subversion repository. The idea is that, if a commit is made on a part someone can't access, this person is not supposed to be able to read the message of the commit either.
EDIT 3 :
If we have a look in the configuration file of trac, we already can find :
permission_policies = AuthzSourcePolicy, DefaultPermissionPolicy, LegacyAttachmentPolicy
and the authz_file variable is properly set too. Moreover, svn access to the private folders of the svn repositories can't be accessed by anonymous users.

You should set up authz checking for both your Subversion repository and your Trac installation. You can use the same permission file for both. For Subversion, see Path-based authorization in the SVN book. For Trac, enable and configure the trac.versioncontrol.svn_authz.AuthzSourcePolicy component.
This will allow you to have a very fine-grained control over who can access which part of the repository. Note that the implementation of AuthzSourcePolicy in Trac 0.12.2 has a few bugs that will be fixed in 0.12.3.

There are two ways of going about this :
1) You can directly edit the plugins that are running in trac, and add a module that helps you to filter these out at the code level (i.e. you can edit the behavior of the script to , say, only include commits which exclude certain key words). The timeline script is here (trac 2.4) : /usr/local/lib/python2.4/site-packages/trac/Timeline.py (here is an online diff snapshot of the source code : http://trac.edgewall.org/attachment/ticket/890/Timeline.py.diff)
2) You can remove the commits entirely - trac commits are derived from the sqlLite database (the schema is here http://trac.edgewall.org/wiki/TracDev/DatabaseSchema).
Of course, there also might be some fancy tools out there that provide a nice interface for editing the way the timeline looks.
Finally - temporarily, you can remove the timeline/roadmap entirely from the trac.ini file : http://www.gossamer-threads.com/lists/trac/users/28079

I confess that I've virtually no experience with the repository part of Trac, even less with using a repository with a variety of permissions across it's contents.
On the subject: Configuration is certainly not enough, see rblanks answer. While I've never seen the code for that functionality, I was wrong to suggest it doesn't exist. Because it is a central place and developed/supported in Trac core this is definitely the way to go.

Exchanging work before accurev promote

My colleague and I are participating in a huge project located in Accurev. We've already created own workspaces backed with some stream (let's call it zzz-stream) which is used by many other participants, not only by us.
The point is that we want to exchange our work between our workspaces, make some changes, exchange again, etc. BEFORE making the changes accessible for others, i.e. in other words we don't want to propagate our changes until it is stable and tested, but we want be able to work on it together.
My idea was to create new stream (yyy-stream) backed with zzz-stream, and then change our workspaces to be backed with yyy-stream. But unfortunately I have no rights to create streams.
My second idea was to use a workspace as backed stream, but it doesn't work because Accurev can't use ws as backed stream.
Is there any solution for our problem?
UPD: I accepted Brad's answer as most detailed. However Accurev is too heavy and sluggish to be used effectively. So actually I prefer to use Git for internal needs over the accurev workspace. (see Accurev externally, git internally)
Your idea of creating the yyy-stream is the EXACT right way to do it. The other options are decent workarounds for one-off situations, but creating the extra stream is simple and is fully leveraging AccuRev's capabilities.
That being said, I understand that your admins have stream creation locked down. They of course want control, but should be allowing for maximizing developer productivity and not forcing workarounds like this. My guess is they have stream creation locked down to a particular group being enforced by the server-admin trigger. One common thing I have seen other large sites do is:
- allow streams to be freely created off of a list of acceptable streams (easy to do in the trigger)
- enforce naming rules on the stream creation. This is important to admins in large sites to keep things organized. Again, this is very easy to enforce via the server-admin trigger.
Bottom line, if this is a common situation, work with the admins to allow this capability as per the above. If they have any questions, they are more than welcome to contact AccuRev and we will help them out.
Your idea on using another stream for you and your peer is a good one and is commonly called a collaboration stream. If your site has stream creation locked down, you would need to work with your AccuRev administrator to make that happen.
Another option is for you and the other developer to pull the keeps from the other workspace into your own stream. This relies on both of you being diligent about doing keeps and then you can look at the history of the other developer's workspace to find the keep operation, right-click that transaction and then select Send to Workspace. The destination workspace must be your own.
A third option (more for a situation where you are in your workspace and know exactly what file you want to grab the other users changes)is to bring up the version browser for the file, right click and select history/browse versions. Look for the other workspace, highlight the version in that workspace, right click and select send to workspace. This will checkout that version into your workspace.
This is similar to the change palette suggestion but quicker if your looking to this on a file basis.
Another idea is to use different version control system (e.g. git or svn) over Accurev workspace to exchange the changes and keep our history separated from zzz-stream. (similar to Accurev externally, git internally) Only changed files should be added to other VCS, not whole project. Some merge problems occur though.

Composite C1 - develop locally, sync to live site

I have a couple of Composite C1 CMS websites.
To edit them currently I use the web based CMS on the live site.
However - I would like to update the (code & content) in Visual Studio locally - then sync to the web. However, if my local copy is older than that online (e.g. a non techy client has edited something on the live site) and I Web Deploy - it will go over the top of the new file on the server.
I need a solution that works out the newest change? I can't find anything in Google or the C1 docs.
How can I sync - preferably using Web Deploy. Do I need some kind of version control?
Is there a best practice for this - editing the live site through the web interface seems a bit dicey & is slow.
The general answer to this type of scenario seems to be to use the Package Creator. With that you can develop locally, add the files you've changed to a package, and install that package on a live site. This solution does not at all cover all the parts of you question though, and has certain limitations:
You cannot selectively add content to a package. It's all pages or no pages.
Adding datatypes is easy, but updating them later requires you to delete the datatype (and data), and recreate the datatype.
In my experience packages works well for incremental site updates, if you limit the packages content to be front end stuff, like css, images and such.
You say you need a solution that works out the newest changes - I believe the only solution to this is yourself, with the aid of some tooling. I don't think there's a silver bullet solution here.
Should you use a version control system? Yes! By all means. Even if you are not sharing your code with anyone, a VCS is a great way to get to know Composite C1 from a file system perspective, as you can carefully track what files are changed on disk, as you develop. This knowledge is crucial when you want to continuously add features the a website that is already alive and kicking - you need to know what to deploy, and what not to touch.
Make sure you read the docs on how Composite fits in VCS: http://docs.composite.net/Configuration/C1-and-Version-Control
I assume that your sites are using the XML data storage (if you where using SQL Data Store, your content would not be overridden upon sync).
This means that your entire web application lives in one folder on disk on the web server, which can be an advantage here.
I'll try to outline a solution that could work for you, although I must stress that I've never tried this - I'm making it up as I type.
Let's say you're using git, download the site in it's entirety from the production web server, and commit the whole damned thing* to your master branch.
Then you create a new feature branch from that commit, and start making the changes you want to deploy later, and carefully commit your work as you go along, making sure you only commit the changes that are needed for your feature to work, to the feature branch.
Now, you are ready to deploy, and you switch back the master branch, and again download the entire site and commit it to master.
You then merge your feature branch into the master branch, and have git do all the hard work of stitching you changes in with the changes from the live site. There are bound to be merge conflicts, and that is where you will have to jump in, and decide for yourself what content needs to go live.
After this is done and tested, you can web deploy the site up to the production environment.
Changes to the live site might have occurred while you where merging, so consider closing the site, or parts of it, during this process.
If you are using SQL Data Store i suggest paying for a tool like Red Gate's SQL Compare and SQL Data Compare or SQL Delta, to compare your dev database to the production database, and hand pick SQL scripts that can be applied to the production database along with your feature deployment.
'* Do consider using a .gitignore file to avoid committing certain files - refer to the docs for mere info.
I suppose you should use the Package Creator

TRAC, hide a project in available projects page depending on permissions

I have multiple projects in TRAC. I'm using mod_wsgi, and my wsgi script file TRAC_ENV_PARENT_DIR variable is pointing to the folder containing folders with all these projects. A few users have access to different projects. When a user visits the TRAC URL, she can see the listing containing all these projects, yet has no access to some of them.
Is there any way to show to a user only those projects this user has access to?
Please advise.
Preamble: I abhor security through obscurity. Your request could be read as cosmetics in web site presentation. Don't aim at improved access control, because knowing a valid path will still give access to each Trac environment depending on it's settings. Of course better navigation is a good reason.
Requiring to hide folders depending on user's permission means you require authentication before granting access to TRAC_ENV_PARENT_DIR. This could be done with standard mechanisms that your web server supports. This is just the precondition.
As you say, you have some non-public Trac instances in your Trac environment folder collection. How complicated it is to identify all folders correctly, that depends on how much you want to spend on initial implementation vs. maintenance.
I should be trivial, but error-prone, to provide a list of either the public or the private directories, of course whatever is easier to maintain. Zero additional configuration would require to open each Trac environment and look up user permissions. )** This sounds rather cumbersome and means probably a performance penalty for applications with large user base and frequent access. You will at least work with a cached list, if you go down this road.
You can't use Trac's auto-generated Available projects list but you'll have to deliver at least two versions of an index page for authenticated/unprivileged and authenticated and privileged users.
For the sake of maintenability you'll want to consolitate configuration and permissions. For access to each Trac environment you could use trac.ini inheritance and a shared .htpasswd file. However you can't inherit permissions, because these settings are stored inside the Trac db. You could give TracUserSyncPlugin a shot, but it seems not yet fit for production, or at least lacks feedback of all the happy users, if they exist.
)** While I'm not aware of dedicated documentation about this, there are actually several possibilities. Since permissions are stored in the Trac db, all involve reading/querying the permission db table. It's structure is documented with all other tables of the Trac db schema. To read you'll want to open the Trac environment(s) and then use a direct query on the table (see a AccountManagerPlugin changeset for an example) or construct and query a PermissionCache object.
It may be an old question, but so far i've found the answers to be rather complex without need.
I think using the information stated here, http://trac.edgewall.org/wiki/TracInterfaceCustomization#ProjectList , one could build a template that checks for users and permissions and then show the data it should.
In my case, i just needed to point the "TRAC_ENV_INDEX_TEMPLATE" variable to blank HTML, and that was enough for me.

Tortoise SVN : Setting different permissions for sub folders

(I am newbie to tortoise SVN)
I have 2 folders in my tortoise SVN.
Each need a different set of authorization
(I do not want
people who have access to the first folder to have read / write access to the second folder).
How can I accomplish it? I noticed that all permissions are defined in a file in the root level.
This is covered in the Subversion Book section on Path Based Authorization. You can check out the link for more details, but I would just draw your attention to this part:
A lot of administrators setting up Subversion for the first time tend to jump into path-based access control without giving it a lot of thought. The administrator usually knows which teams of people are working on which projects, so it's easy to jump in and grant certain teams access to certain directories and not others. It seems like a natural thing, and it appeases the administrator's desire to maintain tight control of the repository.
Note, though, that there are often invisible (and visible!) costs associated with this feature. In the visible category, the server needs to do a lot more work to ensure that the user has the right to read or write each specific path; in certain situations, there's very noticeable performance loss. In the invisible category, consider the culture you're creating. Most of the time, while certain users shouldn't be committing changes to certain parts of the repository, that social contract doesn't need to be technologically enforced. Teams can sometimes spontaneously collaborate with each other; someone may want to help someone else out by committing to an area she doesn't normally work on. By preventing this sort of thing at the server level, you're setting up barriers to unexpected collaboration. You're also creating a bunch of rules that need to be maintained as projects develop, new users are added, and so on. It's a bunch of extra work to maintain.
Just to round the post of codeka up. You can't set (at least I never have found out how) any permissions for the repo in tortoise as it is the SVN client application. You would have to set the permission on your svn server. If you happen to be running VisualSVN Server (free) you can setup user rights in a windows-easy manner (point and click).

Finding which files were "FIXED"and how many times between two specific date by using Trac?

I need to find out that how many times and which files are fixed or changed due to a bug between two specific dates in an open source project which uses Trac. I selected Webkit project for that purpose. (https://trac.webkit.org/) However, it can be any open source project.
What can I do for that? How do I start? Do i have to use version control systems like svn or git for intergration? I am kinda newbie for these bug-tracking and issue-tracking systems.
I'm not certain I exactly understand your question, but...
If you browse to the directory containing the files you care about in the Trac site, then click on Revision Log, you will get a list of changesets that affected that directory. You can select the revisions that span the timeframe of interest and then View changes and you will get a summary of the changes, and depending on the size of the changes and the particular Trac configuration, you may get the diffs on that page as well.
Now, that won't tell you how many times those files were changed, just the net changes.
It also won't tell you which bugs those changes were for.
If you really need to filter on what bug, you'll have to determine how that information is tracked by the particular project; and some might not track it directly. The project might include a #123 in the commit message. If you can rely on that, you could use svn log --xml {2009-11-01}:{2009-12-01} ... to get an xml version of the commit log which you could then parse and filter based on the presence of the bug's ticket number in the commit message. From that, you should have a list of the revisions that you care about.
