Refer to Synchronized Projects User Guide for basic information.
The July 2011 PTP user meeting user-call recording includes a live demonstration of how to setup and configure a synchronized project. (Note: convert to full-screen viewing via the green square in the lower right corner of the screen to be able to read the contents of the demo screens.)
- The "Build directory" in ('Project' -> 'Properties' -> 'C/C++ Build') does not show the correct build location for remote configurations. Builds should still run in the proper location, though, if set correctly in ('Project' -> 'Properties' -> 'C/C++ Build' -> 'Synchronize').
- There is no wizard to convert existing remote projects to synchronized projects. (See FAQ item below for a solution)
- After converting a local project, users should copy the new Remote configuration to create additional remote sites. Copying and altering local configurations will not work bug 358141.
- There are some potential pitfalls when configuring projects
- On the first page of the new project wizard, users should not select a file system other than the default. This directory must be local. Users specify a remote location on the last page of the wizard bug 356208.
- Users should avoid changing configurations inside the new project wizard, as this will cause errors. Instead, add and change configurations after project creation.
- The Workspace configuration only appears after the project is created.
- The tool chain selected during creation is used for both the local machine and remote machine. Users need to adjust this after project creation.
- For remote configurations, only the "Sync Builder" works, although other options are available ('Project' -> 'Properties' -> 'C/C++ Build' -> 'Tool Chain Editor'). The "Sync Builder" is set as the default.
- Attempting to change multiple configurations does not work correctly.
When should I create a Remote Project and when should I create a Synchronized Project?
Remote projects exist only on a single remote site. So they are a better choice if you need a simple, quick way to work remotely. Synchronized projects add the capability to use multiple remote sites and synchronize between them. The underlying Git tool makes sync'ing very efficient, leading to less network lag time, especially for large projects. Also, synchronized projects exist and can be built both locally and remotely. Even if you are not interested in compiling locally, this can be handy if the connection is unavailable or slow. For example, you can work on the project locally and then, once the connection becomes available, sync your changes to the remote site.
Other benefits of Sync'd projects include
- Local editing offers improvements over editing remote file (some features are disabled in the C/C++ remote editor) (Example: greying out of inactive code works in local editor)
- You can have multiple remote configurations and switch between building on different remote systems.
- The Fortran indexer can run on a local project but not a remote project
A remote project doesn't need to bring the source files to the local client until you request a file for editing or other operation. A synchronized project brings all the files to the local client upon initial sync then only needs to sync changes later, so editing of already-synced files is faster.
A synchronized project will need more networking initially to do the initial sync, but subsequent requests such as to fetch a file for editing are not needed since the file exists locally.
How do I setup a synchronized project that works with a CVS repository?
- Create a new CVS project as usual (right-click in 'Project Explorer' -> 'New' -> 'Other...' -> 'CVS' -> 'Projects from CVS")
- Be sure to select "Check out as a project configured using the New Project Wizard" on the "Check Out As" screen
- After the CVS wizard ends, the "New Project Wizard" begins.
- Create an empty Synchronized project
- Files in the CVS repository are automatically imported on project creation
- Check out a project from CVS into a local project as usual (Check out as C or Fortran project if it isn't already)
- File > New > Other... and under Remote, select "Convert C/C++ or Fortran Project to a Synchronized Project" then select the project and setup (or reuse) a remote connection. Be sure to specify a directory on the remote system for 'Location' where the files will be sync'd to.
How do I setup synchronization for an existing C/C++ or Fortran project, including ones that use CVS, Git, SVN, etc.?
The conversion wizard, described in the User Guide, should work for all of these cases. Synchronization works independently of the user's version control system.
Why doesn't a new file that I added on the remote machine appear in my workspace, and how can I add it?
On project creation, all existing remote files are downloaded. Additional new files are not downloaded, though, which prevents the downloading of files that are created during compilation. One workaround is to add the file locally, synchronize, and then edit the file remotely. This works because new local files are synchronized. Also, changes to remote files that are synchronized will be downloaded.
How do I know if a current project is a synchronized project?
Go to the properties page ('Project' -> 'Properties' -> 'C/C++ Build') and see if the 'Synchronize' page is available.
I get a Merge conflict for a file that changed both locally and remotely. How do I recover from this?
Delete the file on the remote system and re-synchronize.
How do I convert an existing remote project to be a synchronized project?
This is currently not supported, but... You can create a new synchronized project and point to the existing location on the remote system. This does not affect the settings of the original remote project.
- Add sync context menu bug 345673.
- Add wizard to convert local C/C++ or Fortran projects to synchronized projects bug 356813.
- Support files with odd characters bug 354893, with the exception of newline characters bug 355270.
- Add ability to turn off error messages bug 355526.
- Fix bug 356633: Failure to add files to repository if a .gitignore file is present.
- Use separate Git directory (.ptp-sync instead of .git) for sync'ing so that it does not interfere with user's Git repository.
- Sync empty directories.
- Prevent users from modifying the synchronization properties of the Workspace configuration.
- Fix bug 349372: Build fails if empty environment variables are present.
- Support managed project types.
