FileOpen Event

Fires when a client wants to open or create a file.

Syntax

type TFileOpenEvent = procedure FileOpen(Sender: TObject; ConnectionId: Integer; const User: String; const Path: String; DesiredAccess: Integer; Flags: Integer; FileType: Integer; FileSize: Int64; const FileOwner: String; const FileGroup: String; FilePermissions: Integer; FileATime: Int64; FileCreateTime: Int64; FileMTime: Int64; FileAttribBits: Integer; FileAttribBitsValid: Integer; const OtherAttributes: String;var Handle: String;var StatusCode: Integer) of object;
property OnFileOpen: TFileOpenEvent read FOnFileOpen write FOnFileOpen;

Remarks

The Path parameter specifies the path and name of the file to open, create. If the operation can be completed successfully, the Handle parameter should be set to the handle identifying the opened file.

The Flags parameter specifies file creation and locking options as a bitmask. This may be a combination of the following values:

  • SSH_FXF_READ (0x00000001)
  • SSH_FXF_WRITE (0x00000002)
  • SSH_FXF_APPEND (0x00000004)
  • SSH_FXF_CREAT (0x00000008)
  • SSH_FXF_TRUNC (0x00000010)
  • SSH_FXF_EXCL (0x00000020)

The DesiredAccess parameter is a bitmask containing a combination of values from the ace-mask flags (Only for protocol versions 4 and up). This may be a combination of the following values:

  • ACE4_READ_DATA (0x00000001)
  • ACE4_LIST_DIRECTORY (0x00000001)
  • ACE4_WRITE_DATA (0x00000002)
  • ACE4_ADD_FILE (0x00000002)
  • ACE4_APPEND_DATA (0x00000004)
  • ACE4_ADD_SUBDIRECTORY (0x00000004)
  • ACE4_READ_NAMED_ATTRS (0x00000008)
  • ACE4_WRITE_NAMED_ATTRS (0x00000010)
  • ACE4_EXECUTE (0x00000020)
  • ACE4_DELETE_CHILD (0x00000040)
  • ACE4_READ_ATTRIBUTES (0x00000080)
  • ACE4_WRITE_ATTRIBUTES (0x00000100)
  • ACE4_DELETE (0x00010000)
  • ACE4_READ_ACL (0x00020000)
  • ACE4_WRITE_ACL (0x00040000)
  • ACE4_WRITE_OWNER (0x00080000)
  • ACE4_SYNCHRONIZE (0x00100000)
Please see RFC 3010 for more information on the semantics of these values.

File/Directory Attributes are specified using the following values:

FileType: The type of file. Can be one of the following values:

  • SSH_FILEXFER_TYPE_REGULAR (1)
  • SSH_FILEXFER_TYPE_DIRECTORY (2)
  • SSH_FILEXFER_TYPE_SYMLINK (3)
  • SSH_FILEXFER_TYPE_SPECIAL (4)
  • SSH_FILEXFER_TYPE_UNKNOWN (5)
  • SSH_FILEXFER_TYPE_SOCKET (6)
  • SSH_FILEXFER_TYPE_CHAR_DEVICE (7)
  • SSH_FILEXFER_TYPE_BLOCK_DEVICE (8)
  • SSH_FILEXFER_TYPE_FIFO (9)

FileSize: The file size, in bytes.

FileOwner: The file owner. If the ProtocolVersion configuration option is "3" (default), this field should be a numeric Unix-like user identifier. V4-V6 of the SFTP Protocol allow an arbitrary string.

FileGroup: The file owner group. If the ProtocolVersion configuration option is "3" (default), this field should be a numeric Unix-like group identifier. V4-V6 of the SFTP Protocol allow an arbitrary string.

FilePermissions: The POSIX-style file permissions.

FileATime: The file last-access time, in milliseconds since Jan 1, 1970 in UTC.

FileCreateTime: The file creation time, in milliseconds since Jan 1, 1970 in UTC.

FileMTime: The file last-modified time, in milliseconds since Jan 1, 1970 in UTC.

FileAttrBits: The file attributes, as a combination of the following values:

  • SSH_FILEXFER_ATTR_FLAGS_READONLY (0x00000001)
  • SSH_FILEXFER_ATTR_FLAGS_SYSTEM (0x00000002)
  • SSH_FILEXFER_ATTR_FLAGS_HIDDEN (0x00000004)
  • SSH_FILEXFER_ATTR_FLAGS_CASE_INSENSITIVE (0x00000008)
  • SSH_FILEXFER_ATTR_FLAGS_ARCHIVE (0x00000010)
  • SSH_FILEXFER_ATTR_FLAGS_ENCRYPTED (0x00000020)
  • SSH_FILEXFER_ATTR_FLAGS_COMPRESSED (0x00000040)
  • SSH_FILEXFER_ATTR_FLAGS_SPARSE (0x00000080)
  • SSH_FILEXFER_ATTR_FLAGS_APPEND_ONLY (0x00000100)
  • SSH_FILEXFER_ATTR_FLAGS_IMMUTABLE (0x00000200)
  • SSH_FILEXFER_ATTR_FLAGS_SYNC (0x00000400)
  • SSH_FILEXFER_ATTR_FLAGS_TRANSLATION_ERR (0x00000800)

FileAttrBitsValid: A mask specifying which bits in FileAttrBits are supported by the server.

OtherAttributes: A semi-colon (';') delimited list of Name=Value pairs of other attributes supported by SFTP. These include:

  • MIMEType (String)
  • AllocationSize (64-bit int)
  • ATimeNS (int): ATime nanoseconds
  • CreateTimeNS (int): CreateTime nanoseconds
  • MTimeNS (int): MTime nanoseconds
  • TextHint (8-bit int)
  • LinkCount (int)
  • UntranslatedName (String)

FileMimeType: The MIME type of the file.
