Detailed Description
Plugin API.
A plugin is a way to implement application-independent reliability and
performance tuning behavior. Plugins are written using the API
described in this document.
A plugin is created by defining a globus_ftp_client_plugin_t which
contains the function pointers and plugin-specific data needed for the
plugin’s operation. It is recommended that a plugin define a a
globus_module_descriptor_t and plugin initialization functions, to
ensure that the plugin is properly initialized.
The functions pointed to in a plugin are called when significant events
in the life of an FTP Client operation occur. Note that plugins will
only be called when the plugin has the function pointer for both the
operation (get, put, list, etc), and the event (connect, authenticate,
command, etc), are defined. The command and response functions are
filtered based on the command_mask defined in the plugin structure.
Every plugin must define copy and destroy functions. The copy
function is called when the plugin is added to an attribute set or a
handle is initialized with an attribute set containing the plugin. The
destroy function is called when the handle or attribute set is
destroyed.

typedef struct globus_i_ftp_client_plugin_t* globus_ftp_client_plugin_t
FTP Client plugin
An FTP Client plugin is used to add restart, monitoring, and
performance tuning operations to the FTP Client library, without
modifying the base API. Multiple plugins may be associated with a
globus_ftp_client_handle_t.

Debugging Plugin
typedef globus_ftp_client_plugin_t*(*
globus_ftp_client_plugin_copy_t)(globus_ftp_client_plugin_t
*plugin_template, void *plugin_specific)
Plugin copy function. This function is used to create a new copy or
reference count a plugin. This function is called by the FTP Client
library when a plugin is added to a handle attribute set, or when a
handle is initialized with an attribute which contains the plugin.
A plugin may not call any of the plugin API functions from it’s
instantiate method.
Parameters:
plugin_template A plugin previously initialized by a call to the
plugin-specific initialization function. by the user.
plugin_specific Plugin-specific data.
Returns:
A pointer to a plugin. This plugin copy must remain valid until the
copy’s destroy function is called on the copy.

globus_ftp_client_plugin_destroy_t
typedef void(*
globus_ftp_client_plugin_destroy_t)(globus_ftp_client_plugin_t *plugin,
void *plugin_specific)
Plugin destroy function. This function is used to free or unreference a
copy of a plugin which was allocated by calling the instantiate
function from the plugin.
Parameters:
plugin The plugin, created by the create function, which is to be
destroyed.
plugin_specific Plugin-specific data.

Plugin connection begin function. This callback is used to notify a
plugin that connection establishment is being done for this client
handle. This notification can occur when a new request is made or when
a restart is done by a plugin.
If a response_callback is defined by a plugin, then that will be once
the connection establishment has completed (successfully or
unsuccessfully).
Parameters:
plugin The plugin which is being notified.
plugin_specific Plugin-specific data.
handle The handle associated with the connection.
Note:
This function will not be called for a get, put, or third-party
transfer operation when a cached connection is used.

the operation will be silently aborted, and then restarted with
potentially a new URL and attributes. Any data buffers which are
currently queued will be cleared and reused once the connection is re-
established.
The user will not receive any notification that a restart has happened.
Each plugin which is interested in get events will receive a get
callback with the restart boolean set to GLOBUS_TRUE.
Parameters:
handle The handle which is associated with the get.
url The source URL of the transfer. This may be different than the
original get’s URL, if the plugin decides to redirect to another
FTP server due to performance or reliability problems with the
original URL.
attr The attributes to use for the new transfer. This may be a
modified version of the original get’s attribute set. This may be
useful when the plugin wishes to send restart markers to the FTP
server to prevent re-sending the data which has already been sent.
restart_marker Plugin-provided restart marker for resuming at a
non-default restart point. This may be used to implement a
persistent restart across process invocations. The default behavior
if this is NULL is to use any restart information which has been
received by the ftp client library while processing this operation
when restarted.
when Absolute time for when to restart the get. The current control
and data connections will be stopped immediately. If this completes
before when, then the restart will be delayed until that time.
Otherwise, it will be immediately restarted.

Restart an existing put. This function will cause the currently
executing transfer operation to be restarted. When a restart happens,
the operation will be silently aborted, and then restarted with
potentially a new URL and attributes. Any data buffers which are
currently queued but not called back will be resent once the connection
is re-established.
The user will not receive any notification that a restart has happened.
Each plugin which is interested in get events will receive a put
callback with the restart boolean set to GLOBUS_TRUE.
Parameters:
handle The handle which is associated with the put.
url The URL of the transfer. This may be different than the
original put’s URL, if the plugin decides to redirect to another
FTP server due to performance or reliability problems with the
original URL. If the put is restarted with a different URL, the
plugin must re-send any data which has already been acknowledged by
it’s callback.
attr The attributes to use for the new transfer. This may be a
modified version of the original put’s attribute set. This may be
useful when the plugin wishes to send restart markers to the FTP
server to prevent re-sending the data which has already been sent.

a modified version of the original transfer’s attribute set. This
may be useful when the plugin wishes to send restart markers to the
FTP server to prevent re-sending the data which has already been
sent.
dest_url The destination URL of the transfer. This may be different
than the original destination URL, if the plugin decides to
redirect to another FTP server due to performance or reliability
problems with the original URL.
dest_attr The attributes to use for the new transfer. This may be a
modified version of the original transfer’s attribute set. This may
be useful when the plugin wishes to send restart markers to the FTP

the currently executing transfer operation to have additional data
channels acquired if the attribute set allows it.
Parameters:
handle The handle which is associated with the transfer.
num_channels The number of channels to add to the transfer.
stripe The stripe number to have the channels added to.
Note:
Do the plugins need to be notified when this happens?
globus_result_t globus_ftp_client_plugin_remove_data_channels
(globus_ftp_client_handle_t * handle, unsigned int num_channels,
unsigned int stripe)
Remove data channels from an existing put transfer. This function will
cause the currently executing transfer operation to have data channels
removed, if the attribute set allows it.
