(** [ftp_fs base_url]: Access the FTP file system rooted at [base_url].
The [base_url] must follow the [ftp://user\@host:port/path] scheme.
Passwords in [base_url] are ignored.
The following access methods are supported (compare with
{!Netfs.stream_fs}). Note that not all FTP servers can perform
all operations:
- [path_encoding]: If the FTP server announces that it uses UTF-8
as path encoding, this is returned here; else [None].
- [path_exclusions]: is just [0,0; 47,47]
- [nominal_dot_dot] is true. "." and ".." are resolved by the client
before sending paths to the server.
- [read]: is supported. Note that FTP distinguishes between text
and binary mode, so don't forget to pass the [`Binary] flag if needed.
The [`Skip] flag is only emulated - the full
file is retrieved first, and only the first bytes are hidden
from the user. There is no support for streaming mode; the
[`Streaming] flag is ignored. This means that the file is first
downloaded to a temporary file, and the returned object is just
a handle for this file.
- [write]: is supported, but - depending on the server - not all
flag combinations. The flag list [[`Create; `Truncate]] should
always work. For other flag lists, the server needs to support
the [MLST] command for checking whether the file already exists.
If this support is missing, an FTP error is raised. It is not
supported to omit both [`Create] and [`Truncate]. Also, the
[`Exclusive] flag is not supported. As for [read], there is no
streaming mode, and a temporary file is used as container.
- [size]: works only if the server supports the [SIZE] command
(otherwise ENOSYS).
- [test] and [test_list]: works only if the server supports the
[MLST] command (otherwise ENOSYS). The tests [`N], [`E], [`D], [`F],
[`S], [`R], [`W], and [`X] should work.
Files are never recognized as symlinks.
- [remove]: works, but the [`Recursive] flag is not supported
(and an emulation is considered as too dangerous)
- [readdir]: works
- [rename]: works
- [mkdir]: works, but the flags are ignored
- [rmdir]: works
There is no support for [symlink], [readlink], and [copy].
Options:
- [config_client]: one can enable further features on the client
object (e.g. proxies)
- [tmp_directory]: directory for temporary files
- [tmp_prefix]: file prefix for temporary files (w/o directory)
- [get_password]: This function should return the password for
the user (passed in as argument). Defaults to "".
- [get_account]: This function should return the account name for
the user (passed in as argument). Defaults to "".
- [keep_open]: By default, a new FTP connection is started for
each operation, and it is shut down afterward. By setting [keep_open]
the connection is kept open. The user has to call [close] when done.
- [tls_config]: The TLS configuration to use. (If not set, a
reasonable default is used.)
- [tls_enabled]: whether TLS is enabled
- [tls_required]: whether TLS is required
- [gssapi_provider]: The GSSAPI provider to use, e.g.
{!Netgss.System}. Note that there is no default, and GSSAPI remains
disabled if this option is not set.
- [gssapi_config]: the client configuration (with a reasonable default)
- [gssapi_required]: whether GSSAPI is required
