Detailed Description

Filesystem Access Contexts.

Since
New in 1.2.

At certain times, filesystem functions need access to temporary user data. For example, which user is changing a file? If the file is locked, has an appropriate lock-token been supplied?

This temporary user data is stored in an "access context" object, and the access context is then connected to the filesystem object. Whenever a filesystem function requires information, it can pull things out of the context as needed.

Typedef Documentation

◆ svn_fs_access_t

An opaque object representing temporary user data.

Definition at line 813 of file svn_fs.h.

Function Documentation

◆ svn_fs_access_add_lock_token()

svn_error_t* svn_fs_access_add_lock_token ( svn_fs_access_t access_ctx,
const char *  token 
)

Same as svn_fs_access_add_lock_token2(), but with path set to value 1.

Deprecated:
Provided for backward compatibility with the 1.5 API.

◆ svn_fs_access_add_lock_token2()

svn_error_t* svn_fs_access_add_lock_token2 ( svn_fs_access_t access_ctx,
const char *  path,
const char *  token 
)

Push a lock-token token associated with path path into the context access_ctx.

The context remembers all tokens it receives, and makes them available to fs functions. The token and path are not duplicated into access_ctx's pool; make sure the token's lifetime is at least as long as access_ctx.

Since
New in 1.6.

◆ svn_fs_access_get_username()

svn_error_t* svn_fs_access_get_username ( const char **  username,
svn_fs_access_t access_ctx 
)

Accessors for the access context:

Set *username to the name represented by access_ctx.

◆ svn_fs_create_access()

svn_error_t* svn_fs_create_access ( svn_fs_access_t **  access_ctx,
const char *  username,
apr_pool_t *  pool 
)

Set *access_ctx to a new svn_fs_access_t object representing username, allocated in pool.

username is presumed to have been authenticated by the caller.

Make a deep copy of username.

◆ svn_fs_set_access()

svn_error_t* svn_fs_set_access ( svn_fs_t fs,
svn_fs_access_t access_ctx 
)

Associate access_ctx with an open fs.

This function can be run multiple times on the same open filesystem, in order to change the filesystem access context for different filesystem operations. Pass a NULL value for access_ctx to disassociate the current access context from the filesystem.
