Detailed Description

Overview of the svn authentication system.

We define an authentication "provider" as a module that is able to return a specific set of credentials. (e.g. username/password, certificate, etc.) Each provider implements a vtable that

can fetch initial credentials
can retry the fetch (or try to fetch something different)
can store the credentials for future use

For any given type of credentials, there can exist any number of separate providers -- each provider has a different method of fetching. (i.e. from a disk store, by prompting the user, etc.)

The application begins by creating an auth baton object, and "registers" some number of providers with the auth baton, in a specific order. (For example, it may first register a username/password provider that looks in disk store, then register a username/password provider that prompts the user.)

Later on, when any svn library is challenged, it asks the auth baton for the specific credentials. If the initial credentials fail to authenticate, the caller keeps requesting new credentials. Under the hood, libsvn_auth effectively "walks" over each provider (in order of registry), one at a time, until all the providers have exhausted all their retry options.

This system allows an application to flexibly define authentication behaviors (by changing registration order), and very easily write new authentication providers.

An auth_baton also contains an internal hashtable of run-time parameters; any provider or library layer can set these run-time parameters at any time, so that the provider has access to the data. (For example, certain run-time data may not be available until an authentication challenge is made.) Each credential type must document the run-time parameters that are made available to its providers.

A type of callback function for asking whether storing a passphrase to disk in plaintext is allowed.

typedef struct svn_auth_provider_object_t svn_auth_provider_object_t

A provider object, ready to be put into an array and given to svn_auth_open().

typedef struct svn_auth_provider_t svn_auth_provider_t

The main authentication "provider" vtable.

typedef svn_error_t*(* svn_auth_simple_prompt_func_t)(svn_auth_cred_simple_t **cred, void *baton, const char *realm, const char *username, svn_boolean_t may_save, apr_pool_t *pool)

Credential-constructing prompt functions.

These exist so that different client applications can use different prompt mechanisms to supply the same credentials. For example, if authentication requires a username and password, a command-line client's prompting function might prompt first for the username and then for the password, whereas a GUI client's would present a single dialog box asking for both, and a telepathic client's would read all the information directly from the user's mind. All these prompting functions return the same type of credential, but the information used to construct the credential is gathered in an interface-specific way in each case. Set *cred by prompting the user, allocating *cred in pool. baton is an implementation-specific closure.

If realm is non-NULL, maybe use it in the prompt string.

If username is non-NULL, then the user might be prompted only for a password, but *cred would still be filled with both username and password. For example, a typical usage would be to pass username on the first call, but then leave it NULL for subsequent calls, on the theory that if credentials failed, it's as likely to be due to incorrect username as incorrect password.

If may_save is FALSE, the auth system does not allow the credentials to be saved (to disk). A prompt function shall not ask the user if the credentials shall be saved if may_save is FALSE. For example, a GUI client with a remember password checkbox would grey out the checkbox if may_save is FALSE.

Definition at line 373 of file svn_auth.h.

typedef void(* svn_auth_simple_provider_func_t)(svn_auth_provider_object_t **provider, apr_pool_t *pool)

The type of function returning authentication provider.

Set *cred by prompting the user, allocating *cred in pool.

baton is an implementation-specific closure. realm is a string that can be used in the prompt string.

If may_save is FALSE, the auth system does not allow the credentials to be saved (to disk). A prompt function shall not ask the user if the credentials shall be saved if may_save is FALSE.

Set *cred by prompting the user, allocating *cred in pool.

baton is an implementation-specific closure. realm is a string identifying the certificate, and can be used in the prompt string.

typedef svn_error_t*(* svn_auth_ssl_server_trust_prompt_func_t)(svn_auth_cred_ssl_server_trust_t **cred, void *baton, const char *realm, apr_uint32_t failures, const svn_auth_ssl_server_cert_info_t *cert_info, svn_boolean_t may_save, apr_pool_t *pool)

Set *cred by prompting the user, allocating *cred in pool.

baton is an implementation-specific closure.

cert_info is a structure describing the server cert that was presented to the client, and failures is a bitmask that describes exactly why the cert could not be automatically validated, composed from the constants SVN_AUTH_SSL_* (SVN_AUTH_SSL_NOTYETVALID etc.). realm is a string that can be used in the prompt string.

If may_save is FALSE, the auth system does not allow the credentials to be saved (to disk). A prompt function shall not ask the user if the credentials shall be saved if may_save is FALSE. For example, a GUI client with a trust permanently checkbox would grey out the checkbox if may_save is FALSE.

Function Documentation

svn_error_t* svn_auth_first_credentials	(	void **	credentials,
		svn_auth_iterstate_t **	state,
		const char *	cred_kind,
		const char *	realmstring,
		svn_auth_baton_t *	auth_baton,
		apr_pool_t *	pool
	)

Get an initial set of credentials.

Ask auth_baton to set *credentials to a set of credentials defined by cred_kind and valid within realmstring, or NULL if no credentials are available. Otherwise, return an iteration state in *state, so that the caller can call svn_auth_next_credentials(), in case the first set of credentials fails to authenticate.

Use pool to allocate *state, and for temporary allocation. Note that *credentials will be allocated in auth_baton's pool.

const void* svn_auth_get_parameter	(	svn_auth_baton_t *	auth_baton,
		const char *	name
	)

Get an authentication run-time parameter.

Return a value for run-time parameter name from auth_baton. Return NULL if the parameter doesn't exist.

svn_error_t* svn_auth_next_credentials	(	void **	credentials,
		svn_auth_iterstate_t *	state,
		apr_pool_t *	pool
	)

Get another set of credentials, assuming previous ones failed to authenticate.

Use state to fetch a different set of *credentials, as a follow-up to svn_auth_first_credentials() or svn_auth_next_credentials(). If no more credentials are available, set *credentials to NULL.

Note that *credentials will be allocated in auth_baton's pool.

void svn_auth_open	(	svn_auth_baton_t **	auth_baton,
		apr_array_header_t *	providers,
		apr_pool_t *	pool
	)

Initialize an authentication system.

Return an authentication object in *auth_baton (allocated in pool) that represents a particular instance of the svn authentication system. providers is an array of svn_auth_provider_object_t pointers, already allocated in pool and intentionally ordered. These pointers will be stored within *auth_baton, grouped by credential type, and searched in this exact order.

svn_error_t* svn_auth_save_credentials	(	svn_auth_iterstate_t *	state,
		apr_pool_t *	pool
	)

Save a set of credentials.

Ask state to store the most recently returned credentials, presumably because they successfully authenticated. All allocations should be done in pool.

If no credentials were ever returned, do nothing.

void svn_auth_set_parameter	(	svn_auth_baton_t *	auth_baton,
		const char *	name,
		const void *	value
	)

Set an authentication run-time parameter.

Store name / value pair as a run-time parameter in auth_baton, making the data accessible to all providers. name and value will NOT be duplicated into the auth_baton's pool. To delete a run-time parameter, pass NULL for value.
