Detailed Description

Handle attributes are used to control additional features of the FTP Client handle. These features are operation independent.

The attribute which can currently set on a handle concern the connection caching behavior of the handle, and the associations of plugins with a handle.

Handle Attributes.

Handle attributes are used to control the caching behavior of the ftp client handle, and to implement the plugin features for reliability and performance tuning.

Function Documentation

globus_result_t globus_ftp_client_handleattr_add_cached_url (globus_ftp_client_handleattr_t * attr, const char * url)

Enable/Disable caching for a specific URL.

This function adds/removes the specified URL into the default cache for a handle attribute. Handles initialized with this attr will keep connections to FTP servers associated with the URLs in its cache open between operations .


attr Attribute to modify
url URL string to cache

globus_result_t globus_ftp_client_handleattr_add_plugin (globus_ftp_client_handleattr_t * attr, globus_ftp_client_plugin_t * plugin)

Add/Remove a plugin to a handle attribute set.

Each handle attribute set contains a list of plugins associated with it. When a handle is created with a particular attribute set, it will be associated with a copy of those plugins.

Only one instance of a specific plugin may be added to an attribute set. Each plugin must have a different name.

A copy of the plugin is created via the plugins 'copy' method when it is added to an attribute set. Thus, any changes to a particular plugin must be done before the plugin is added to an attribute set, and before the attribute set is used to create handles.


attr The attribute set to modify.
plugin The plugin to add or remove from the list.

globus_result_t globus_ftp_client_handleattr_copy (globus_ftp_client_handleattr_t * dest, globus_ftp_client_handleattr_t * src)

Create a duplicate of a handle attribute set.

The duplicated attribute set has a deep copy of all data in the attribute set, so the original may be destroyed while the copy is still valid.


dest The attribute set to be initialized to the same values as src.
src The original attribute set to duplicate.

globus_result_t globus_ftp_client_handleattr_destroy (globus_ftp_client_handleattr_t * attr)

Destroy an FTP client handle attribute set.

This function destroys an ftp client handle attribute set. All attributes on this set will be lost. The user must call globus_ftp_client_handleattr_init() again on this attribute set before calling any other handle attribute functions on it.


attr The attribute set to destroy.

globus_result_t globus_ftp_client_handleattr_init (globus_ftp_client_handleattr_t * attr)

Initialize an FTP client handle attribute set.

This function creates an empty FTP Client handle attribute set. This function must be called on each attribute set before any of the other functions in this section may be called.


attr The new handle attribute.

globus_result_t globus_ftp_client_handleattr_set_cache_all (globus_ftp_client_handleattr_t * attr, globus_bool_t cache_all)

Set/Get the cache all connections attribute for an ftp client handle attribute set.

This attribute allows the user to cause all control connections to be cached between ftp operations. When this is enabled, the user skips the authentication handshake and connection establishment overhead for multiple subsequent ftp operations to the same server.

Memory and network connections associated with the caching will be used until the handle is destroyed. If fine grained caching is needed, then the user should disable this attribute and explicitly cache specific URLs.


attr Attribute to query or modify.
cache_all Value of the cache_all attribute.

globus_ftp_client_handleattr_add_cached_url(), globus_ftp_client_handleattr_remove_cached_url(), globus_ftp_client_handle_cache_url_state() globus_ftp_client_handle_flush_url_state()

globus_result_t globus_ftp_client_handleattr_set_clientinfo (globus_ftp_client_handleattr_t * attr, const char * app_name, const char * app_version, const char * other)

Set/Get client info reported to server.


attr Attribute to modify
app_name Name of client application.
app_version Client application specific version string.
other Additional client info to be reported to the server. This may be used to pass custom info to a custom server module. The format of the string must be: key1='value1';key2='value2';[keyn='valuen';]

Any parameter may be NULL. By default, generic library info will be reported to the server -- set all NULL to disable this.

globus_result_t globus_ftp_client_handleattr_set_gridftp2 (globus_ftp_client_handleattr_t * attr, globus_bool_t gridftp2)

Enable/Disable GridFTP2 [GFD.41] support for servers supporting it. This currently only applies to the GET/PUT command.


attr Attribute to modify
gridftp2 Set to GLOBUS_FALSE to disable GridFTP2 support. GridFTP2 support is enabled by default for servers that support it.

globus_result_t globus_ftp_client_handleattr_set_netlogger (globus_ftp_client_handleattr_t * attr, globus_netlogger_handle_t * nl_handle)

Set the netlogger handle used with this transfer.

Each handle can have a netlogger handle associated with it for logging its data.

Only 1 netlogger handle can be associated with a client handle.


attr The attribute set to modify.
nl_handle The open netlogger handle to be associated with this attribute set.

globus_result_t globus_ftp_client_handleattr_set_pipeline (globus_ftp_client_handleattr_t * attr, globus_size_t outstanding_commands, globus_ftp_client_pipeline_callback_t pipeline_callback, void * pipeline_arg)

Enable/Disable command queueing for pipelined transfers.


attr Attribute to modify
outstanding_commands Set to the number of commands to have sent without receiving a reply. Use 0 for the library default.
pipeline_callback Set to a function of type globus_ftp_client_pipeline_callback_t to enable command pipelining. This function will be called during a transfer operation to request the next urls to be transferred.
pipeline_arg User data that will be passed in the pipeline_callback.

globus_result_t globus_ftp_client_handleattr_set_rfc1738_url (globus_ftp_client_handleattr_t * attr, globus_bool_t rfc1738_url)

Enable/Disable rfc1738 support for non-root relative URLs.


attr Attribute to modify
rfc1738_url Set to GLOBUS_TRUE to enable non-root relative URLs. Default of GLOBUS_FALSE specifies root-relative URLs.
