Detailed Description

Operation attributes are used to control the security and performance of an FTP operation.

These features are often dependent on the capabilities of the FTP server which you are going to access.

Typedef Documentation

typedef struct globus_i_ftp_client_operationattr_t* globus_ftp_client_operationattr_t

Operation Attributes. FTP Client attributes are used to control the parameters needed to access an URL using the FTP protocol. Attributes are created and manipulated using the functions in the attributes section of the library.

Set/Get the TCP buffer attribute for an ftp client attribute set. This attribute allows the user to control the TCP buffer size used for all data channels used in a file transfer. The size of the TCP buffer can make a significant impact on the performance of a file transfer. The user may set the buffer to either a system-dependent default value, or to a fixed value.

The actual implementation of this attribute is designed to be as widely interoperable as possible. In addition to supporting the SBUF command described in the GridFTP protocol extensions document, it also supports other commands and site commands which are used by other servers to set TCP buffer sizes. These are

• SITE RETRBUFSIZE
• SITE RBUFSZ
• SITE RBUFSIZ
• SITE STORBUFIZE
• SITE SBUFSZ
• SITE SBUFSIZ
• SITE BUFSIZE

This attribute is affects any type of data transfer done with the ftp client library.

Parameters:

attr The attribute set to query or modify.
tcp_buffer The value of tcp_buffer attribute.

globus_gsiftp_control_tcpbuffer_t

globus_result_t globus_ftp_client_operationattr_set_type (globus_ftp_client_operationattr_t * attr, globus_ftp_control_type_t type)

Set/Get the file representation type attribute for an ftp client attribute set. This attribute allows the user to choose the file type used for an FTP file transfer. The file may be transferred as either ASCII or a binary image.

When transferring an ASCII file, the data will be transformed in the following way

• the high-order bit will be set to zero
• end-of line characters will be converted to a CRLF pair for the data transfer, and then converted to native format before being returned to the user's data callbacks.

The default type for the ftp client library is binary.

Parameters:

attr The attribute set to query or modify.
type The value of type attribute.

See also:

globus_ftp_control_type_t

globus_result_t globus_ftp_client_operationattr_set_mode (globus_ftp_client_operationattr_t * attr, globus_ftp_control_mode_t mode)

Set/Get the file transfer mode attribute for an ftp client attribute set. This attribute allows the user to choose the data channel protocol used to transfer a file. There are two modes supported by this library: stream mode and extended block mode.

Stream mode is a file transfer mode where all data is sent over a single TCP socket, without any data framing. In stream mode, data will arrive in sequential order. This mode is supported by nearly all FTP servers.

Extended block mode is a file transfer mode where data can be sent over multiple parallel connections and to multiple data storage nodes to provide a high-performance data transfer. In extended block mode, data may arrive out-of-order. ASCII type files are not supported in extended block mode.

Parameters:

attr The attribute set to query or modify.
mode The value of mode attribute

See also:

globus_ftp_control_mode_t, globus_ftp_client_operationattr_set_parallelism(), globus_ftp_client_operationattr_set_layout()

Note:

Extended block mode is a Grid-FTP extension, and may not be supported on all FTP servers.

This attribute allows the user to allow list data to be transferred using the current data channel mode. Parameters:

attr The attribute set to query or modify.
list_uses_data_mode globus_bool_t

Note:

List data transfers in nonstandard modes is a Grid-FTP extension, and may not be supported on all FTP servers.

globus_result_t globus_ftp_client_operationattr_set_delayed_pasv (const globus_ftp_client_operationattr_t * attr, globus_bool_t delayed_pasv)

Set/Get whether or not delayed passive should be used

This attribute allows the user to enable delayed passive so the server can provide the passive address after it knows the filename to be transferred. Parameters:

attr The attribute set to query or modify.
delayed_pasv globus_bool_t

Note:

Delayed passive is a GridFTP extension, and may not be supported on all FTP servers.

globus_result_t globus_ftp_client_operationattr_set_authorization (globus_ftp_client_operationattr_t * attr, gss_cred_id_t credential, const char * user, const char * password, const char * account, const char * subject)

Set/Get the authorization attribute for an ftp client attribute set. This attribute allows the user to pass authentication information to the ftp client library. This information is used to authenticate with the ftp server.

The Globus FTP client library supports authentication using either the GSSAPI, or standard plaintext username and passwords. The type of authentication is determined by the URL scheme which is used for the individual get, put, or 3rd party transfer calls.

Parameters:

attr The attribute set to query or modify.
credential The credential to use for authenticating with a GSIFTP server. This may be GSS_C_NO_CREDENTIAL to use the default credential.
user The user name to send to the FTP server. When doing a gsiftp transfer, this may be set to NULL, and the default globusmap entry for the user's GSI identity will be usd.
password The password to send to the FTP server. When doing a gsiftp transfer, this may be set to NULL.
account The account to use for the data transfer. Most FTP servers do not require this.
subject The subject name of the FTP server. This is only used when doing a gsiftp transfer, and then only when the security subject name does not match the hostname of the server (ie, when the server is being run by a user).

globus_result_t globus_ftp_client_operationattr_set_dcau (globus_ftp_client_operationattr_t * attr, const globus_ftp_control_dcau_t * dcau)

Set/Get the data channel authentication attribute for an ftp client attribute set. Data channel authentication is a GridFTP extension, and may not be supported by all servers. If a server supports it, then the default is to delegate a credential to the server, and authenticate all data channels with that delegated credential.

Parameters:

attr The attribute set to query or modify.
dcau The value of data channel authentication attribute.

globus_result_t globus_ftp_client_operationattr_set_data_protection (globus_ftp_client_operationattr_t * attr, globus_ftp_control_protection_t protection)

attr The attribute set to query or modify.
protection The value of data channel protection attribute.

Bug

Only safe and private protection levels are supported by gsiftp.

globus_result_t globus_ftp_client_operationattr_set_control_protection (globus_ftp_client_operationattr_t * attr, globus_ftp_control_protection_t protection)

Set/Get the control channel protection attribute for an ftp client attribute set. The control channel protection attribute allows the user to decide whether to encrypt or integrity check the command session between the client and the FTP server. This attribute is only relevant if used with a gsiftp URL.

Parameters:

attr The attribute set to query or modify.
protection The value of control channel protection attribute.

Bug

The clear and safe protection levels are treated identically, with the client integrity checking all commands. The confidential and private protection levels are treated identically, with the client encrypting all commands.

globus_result_t globus_ftp_client_operationattr_set_append (globus_ftp_client_operationattr_t * attr, globus_bool_t append)

Set/Get the append attribute for an ftp client attribute set. This attribute allows the user to append to a file on an FTP server, instead of replacing the existing file when doing a globus_ftp_client_put() or globus_ftp_client_transfer().

This attribute is ignored on the retrieving side of a transfer, or a globus_ftp_client_get().

Parameters:

attr The attribute set to query or modify.
append The value of append attribute.

globus_result_t globus_ftp_client_operationattr_set_read_all (globus_ftp_client_operationattr_t * attr, globus_bool_t read_all, globus_ftp_client_data_callback_t intermediate_callback, void * intermediate_callback_arg)

Set/Get the read_all attribute for an ftp client attribute set. This attribute allows the user to pass in a single buffer to receive all of the data for the current transfer. This buffer must be large enough to hold all of the data for the transfer. Only one buffer may be registered with globus_ftp_client_register_read() when this attribute is used for a get.

In extended block mode, this attribute will cause data to be stored directly into the buffer from multiple streams without any extra data copies.

If the user sets the intermediate callback to a non-null value, this function will be called whenever an intermediate sub-section of the data is received into the buffer.

This attribute is ignored for globus_ftp_client_put() or globus_ftp_client_third_party_transfer() operations.

Parameters:

attr The attribute set to query or modify.
read_all The value of read_all attribute.
intermediate_callback Callback to be invoked when a subsection of the data has been retreived. This callback may be GLOBUS_NULL, if the user only wants to be notified when the data transfer is completed.

Note:

This is a Grid-FTP extension, and may not be supported on all FTP servers.

globus_result_t globus_ftp_client_operationattr_get_layout (const globus_ftp_client_operationattr_t * attr, globus_ftp_control_layout_t * layout)

Set/Get the layout attribute for an ftp client attribute set. This attribute allows the user to control the layout of a file being transfered to a striped Grid-FTP server. The striping layout defines what regions of a file will be stored on each stripe of a multiple-striped ftp server.

The layout attribute is used only when the data is being stored on the server (on a put or 3rd party transfer). This attribute is ignored for stream mode data transfers.

Parameters:

attr The attribute set to query or modify.
layout The value of layout attribute.

globus_ftp_control_layout_t, globus_ftp_client_operationattr_set_parallelism(), globus_ftp_client_operationattr_set_mode()

Note:

This is a Grid-FTP extension, and may not be supported on all FTP servers.

globus_result_t globus_ftp_client_operationattr_get_tcp_buffer (const globus_ftp_client_operationattr_t * attr, globus_ftp_control_tcpbuffer_t * tcp_buffer)

Set/Get the TCP buffer attribute for an ftp client attribute set. This attribute allows the user to control the TCP buffer size used for all data channels used in a file transfer. The size of the TCP buffer can make a significant impact on the performance of a file transfer. The user may set the buffer to either a system-dependent default value, or to a fixed value.

The actual implementation of this attribute is designed to be as widely interoperable as possible. In addition to supporting the SBUF command described in the GridFTP protocol extensions document, it also supports other commands and site commands which are used by other servers to set TCP buffer sizes. These are

• SITE RETRBUFSIZE
• SITE RBUFSZ
• SITE RBUFSIZ
• SITE STORBUFIZE
• SITE SBUFSZ
• SITE SBUFSIZ
• SITE BUFSIZE

This attribute is affects any type of data transfer done with the ftp client library.

Parameters:

attr The attribute set to query or modify.
tcp_buffer The value of tcp_buffer attribute.

globus_gsiftp_control_tcpbuffer_t

globus_result_t globus_ftp_client_operationattr_get_type (const globus_ftp_client_operationattr_t * attr, globus_ftp_control_type_t * type)

Set/Get the file representation type attribute for an ftp client attribute set. This attribute allows the user to choose the file type used for an FTP file transfer. The file may be transferred as either ASCII or a binary image.

When transferring an ASCII file, the data will be transformed in the following way

• the high-order bit will be set to zero
• end-of line characters will be converted to a CRLF pair for the data transfer, and then converted to native format before being returned to the user's data callbacks.

The default type for the ftp client library is binary.

Parameters:

attr The attribute set to query or modify.
type The value of type attribute.

globus_ftp_control_type_t

globus_result_t globus_ftp_client_operationattr_get_mode (const globus_ftp_client_operationattr_t * attr, globus_ftp_control_mode_t * mode)

Set/Get the file transfer mode attribute for an ftp client attribute set. This attribute allows the user to choose the data channel protocol used to transfer a file. There are two modes supported by this library: stream mode and extended block mode.

Stream mode is a file transfer mode where all data is sent over a single TCP socket, without any data framing. In stream mode, data will arrive in sequential order. This mode is supported by nearly all FTP servers.

Extended block mode is a file transfer mode where data can be sent over multiple parallel connections and to multiple data storage nodes to provide a high-performance data transfer. In extended block mode, data may arrive out-of-order. ASCII type files are not supported in extended block mode.

Parameters:

attr The attribute set to query or modify.
mode The value of mode attribute

See also:

globus_ftp_control_mode_t, globus_ftp_client_operationattr_set_parallelism(), globus_ftp_client_operationattr_set_layout()

Note:

Extended block mode is a Grid-FTP extension, and may not be supported on all FTP servers.

globus_result_t globus_ftp_client_operationattr_get_list_uses_data_mode (const globus_ftp_client_operationattr_t * attr, globus_bool_t * list_uses_data_mode)

Set/Get whether or not list data will use the current data mode

This attribute allows the user to allow list data to be transferred using the current data channel mode. Parameters:

attr The attribute set to query or modify.
list_uses_data_mode globus_bool_t

Note:

List data transfers in nonstandard modes is a Grid-FTP extension, and may not be supported on all FTP servers.

globus_result_t globus_ftp_client_operationattr_get_authorization (const globus_ftp_client_operationattr_t * attr, gss_cred_id_t * credential, char ** user, char ** password, char ** account, char ** subject)

Set/Get the authorization attribute for an ftp client attribute set. This attribute allows the user to pass authentication information to the ftp client library. This information is used to authenticate with the ftp server.

The Globus FTP client library supports authentication using either the GSSAPI, or standard plaintext username and passwords. The type of authentication is determined by the URL scheme which is used for the individual get, put, or 3rd party transfer calls.

Parameters:

attr The attribute set to query or modify.
credential The credential to use for authenticating with a GSIFTP server. This may be GSS_C_NO_CREDENTIAL to use the default credential.
user The user name to send to the FTP server. When doing a gsiftp transfer, this may be set to NULL, and the default globusmap entry for the user's GSI identity will be usd.
password The password to send to the FTP server. When doing a gsiftp transfer, this may be set to NULL.
account The account to use for the data transfer. Most FTP servers do not require this.
subject The subject name of the FTP server. This is only used when doing a gsiftp transfer, and then only when the security subject name does not match the hostname of the server (ie, when the server is being run by a user).

globus_result_t globus_ftp_client_operationattr_get_dcau (const globus_ftp_client_operationattr_t * attr, globus_ftp_control_dcau_t * dcau)

Set/Get the data channel authentication attribute for an ftp client attribute set. Data channel authentication is a GridFTP extension, and may not be supported by all servers. If a server supports it, then the default is to delegate a credential to the server, and authenticate all data channels with that delegated credential.

Parameters:

attr The attribute set to query or modify.
dcau The value of data channel authentication attribute.

globus_result_t globus_ftp_client_operationattr_get_data_protection (const globus_ftp_client_operationattr_t * attr, globus_ftp_control_protection_t * protection)

Set/Get the data channel protection attribute for an ftp client attribute set. Parameters:

attr The attribute set to query or modify.
protection The value of data channel protection attribute.

Bug

Only safe and private protection levels are supported by gsiftp.

globus_result_t globus_ftp_client_operationattr_get_control_protection (const globus_ftp_client_operationattr_t * attr, globus_ftp_control_protection_t * protection)

Set/Get the control channel protection attribute for an ftp client attribute set. The control channel protection attribute allows the user to decide whether to encrypt or integrity check the command session between the client and the FTP server. This attribute is only relevant if used with a gsiftp URL.

Parameters:

attr The attribute set to query or modify.
protection The value of control channel protection attribute.

Bug

The clear and safe protection levels are treated identically, with the client integrity checking all commands. The confidential and private protection levels are treated identically, with the client encrypting all commands.

globus_result_t globus_ftp_client_operationattr_get_append (const globus_ftp_client_operationattr_t * attr, globus_bool_t * append)

Set/Get the append attribute for an ftp client attribute set. This attribute allows the user to append to a file on an FTP server, instead of replacing the existing file when doing a globus_ftp_client_put() or globus_ftp_client_transfer().

This attribute is ignored on the retrieving side of a transfer, or a globus_ftp_client_get().

Parameters:

attr The attribute set to query or modify.
append The value of append attribute.

globus_result_t globus_ftp_client_operationattr_get_allow_ipv6 (const globus_ftp_client_operationattr_t * attr, globus_bool_t * allow_ipv6)

Set/Get the allow ipv6 attribute for an ftp client attribute set. This attribute allows client library to make use of ipv6 when possible.

Use of this is currently very experimental.

Parameters:

attr The attribute set to query or modify.
allow_ipv6 GLOBUS_TRUE to allow ipv6 or GLOBUS_FALSE to disallow(default)

globus_result_t globus_ftp_client_operationattr_get_read_all (const globus_ftp_client_operationattr_t * attr, globus_bool_t * read_all, globus_ftp_client_data_callback_t * intermediate_callback, void ** intermediate_callback_arg)

Set/Get the read_all attribute for an ftp client attribute set. This attribute allows the user to pass in a single buffer to receive all of the data for the current transfer. This buffer must be large enough to hold all of the data for the transfer. Only one buffer may be registered with globus_ftp_client_register_read() when this attribute is used for a get.

In extended block mode, this attribute will cause data to be stored directly into the buffer from multiple streams without any extra data copies.

If the user sets the intermediate callback to a non-null value, this function will be called whenever an intermediate sub-section of the data is received into the buffer.

This attribute is ignored for globus_ftp_client_put() or globus_ftp_client_third_party_transfer() operations.

Parameters:

attr The attribute set to query or modify.
read_all The value of read_all attribute.
intermediate_callback Callback to be invoked when a subsection of the data has been retreived. This callback may be GLOBUS_NULL, if the user only wants to be notified when the data transfer is completed.
intermediate_callback_arg User data to be passed to the intermediate callback function.
