Subversion

This page contains descriptions of Subversion-specific fields and options available when setting up a VCS root.

Common VCS root properties are described here.

SVN Connection Settings

Option	Description
URL	Specify the SVN URL that points to the project sources.
Username	Specify the SVN username.
Password	Specify the SVN password.
Configuration directory	You can specify an alternative subversion configuration directory, or use the default one (recommended). This setting also applies to agent-side checkout. TeamCity does not store authentication in SVN configuration directory, but can read settings stored there.
Use default configuration directory	Enable this option to make this the default configuration directory for the SVN connection.
Externals support	Select one of the following options to control the SVN externals processing. Full support (load changes and checkout): TeamCity will check out all configuration's sources (including the sources from the externals) and will gather and display information about externals' changes on the Changes tab. Checkout, but ignore changes: TeamCity will check out the sources from externals but any changes in externals' source files will not be gathered and displayed on the Changes tab. You can use this option if you have several SVN externals and do not want to get information about any changes made in the externals' source files. Build revision number impact If you use the "Checkout, but ignore changes" option, TeamCity will always use the latest repository revision as the revision for a checkout (the same revision will be used for the `build.vcs.number` parameter). For other two options, TeamCity takes the revision of the latest detected change as the revision for a checkout. Ignore externals: TeamCity will ignore any configured `svn:externals` property, and thus TeamCity will not check for changes or check out any source file from the SVN externals. Subversion Repository UUID TeamCity relies on Subversion repository UUID as an unique identifier of a repository. If you have 2 different repositories with the same UUID (due to repository copy) TeamCity may function incorrectly, for instance, wrong HEAD revision of an external repository can be checked out.
HTTPS Connections: Accept non-trusted SSL certificates	If enabled, TeamCity is able to connect to SVN servers without properly signed SSL certificate.

SSH settings

Option	Description
Private Key File Path	Specify the full path to the file that contains the OpenSSH-formatted private key. You can also specify an SSH key uploaded to TeamCity
Private Key File Password	Enter the password to the SSH private key.
SSH Port	Specify the port used by SSH.

Option

Description

Private Key File Path

Specify the full path to the file that contains the OpenSSH-formatted private key.

You can also specify an SSH key uploaded to TeamCity

Private Key File Password

Enter the password to the SSH private key.

SSH Port

Specify the port used by SSH.

Only the OpenSSH format is supported for the key. The key in a format unsupported by TeamCity has to be converted to the OpenSSH format (for example, a Putty private key (*.ppk) can be converted using PuTTYgen.exe: see Conversions | Export OpenSSH key ).

Checkout on agent settings

Option	Description
Working copy format	Select the format of the working copy. Available values for this option are 1.4 through 1.8 (current default). This option defines the format version of Subversion files located in `.svn` directories, when the checkout on agent mode is used. The specified format is important in two cases: If you run command-line `svn` commands on the files checked out by TeamCity. For example, if your working copy has version 1.5, you will not be able to use Subversion 1.4 binaries to work with it. If you use new Subversion features; for example, file-based externals which were added in Subversion 1.6. Thus, unless you set the working copy format to 1.6, the file-based externals will not be available in the checkout on agent mode.
Revert before update	If the option is selected, then TeamCity always runs the `svn revert` command before updating sources; that is, it will revert all changes in versioned files located in the checkout directory. When the option is disabled and local modifications are detected during the update process, TeamCity runs the `svn revert` after the update. TeamCity does not delete non-versioned files in the working directory during the revert. For deleting non-versioned files, consider using Swabra.

Working copy format

Select the format of the working copy. Available values for this option are 1.4 through 1.8 (current default).
This option defines the format version of Subversion files located in .svn directories, when the checkout on agent mode is used. The specified format is important in two cases:

If you run command-line svn commands on the files checked out by TeamCity. For example, if your working copy has version 1.5, you will not be able to use Subversion 1.4 binaries to work with it.

Revert before update

If the option is selected, then TeamCity always runs the svn revert command before updating sources; that is, it will revert all changes in versioned files located in the checkout directory. When the option is disabled and local modifications are detected during the update process, TeamCity runs the svn revert after the update.
TeamCity does not delete non-versioned files in the working directory during the revert. For deleting non-versioned files, consider using Swabra.

Labeling settings

Option	Description
Labeling rules	Specify a newline-delimited set of rules that defines the structure of the repository. See the detailed format description for more details.

Authentication for SVN externals

TeamCity does not allow specifying SVN externals authentication parameters explicitly, in user interface. To authenticate on the SVN externals server, the following approaches are used:

authenticate using the same credentials (username/password) as for the main repository
authenticate without explicit username/password. In this case, the credentials should be already available to the svn process (usually, they stored in subversion configuration directory). So, this require setting correct "Configuration Directory" or "Default Config Directory" option under SVN Connection Settings

When TeamCity has to connect to a SVN external, it uses the following sequence:

if the SVN external URL has the same prefix as the main repository (there is a match > 20 characters), TeamCity tries the main repository credentials first, and in case of a failure tries to connect without the username/password (so they picked up from SVN configuration directory)
if the SVN external URL noticeably differs from the main repository, TeamCity tries to connect without the username/password, and in case of a failure, tries using the credentials from the main repository

Timeouts

Sometimes, the SVN checkout operation for remote SVN servers may fail with an error like svn: E175002: timed out waiting for server. Usually this can happen due to network slowness or the SVN server overload.The timeout values for the connection and for read operations can be configured.

Connection timeout

Connection timeout is applied when TeamCity creates a connection to the SVN server. The default timeout for this operation is 60 seconds, and can be specified via the teamcity.svn.connect.timeout property, in seconds.

For agent-side checkout, add a start-up property.

Read timeout

The read timeout is used when a connection with the SVN server is established, and TeamCity is waiting for the data from the server. The value of the timeout depends on the SVN server access protocol.

Subversion server access via HTTP/HTTPS (both server/agent)

For HTTP read timeout TeamCity uses the http-timeout setting specified in the servers file in the Subversion configuration directory. On Win32 systems, this directory is typically located the Application Data area of the user's profile directory. On Unix/Mac, this directory is usually named $HOME/.subversion for the user account who runs the TeamCity server/agent.

If not specified, the default value for the timeout is 1 hour.

Subversion server access via svn:// or svn+ssh://

In this case, the read timeout can be specified in seconds via the TeamCity teamcity.svn.read.timeout internal property. The default value is 30 minutes.

For agent-side checkout, add a start-up property.

Ignored changes

TeamCity ignores changes in the svn:mergeinfo properties and does not consider a directory changed if only these properties are modified in a given commit.
