ftputil 4.0.0 released

Show all headers | View raw

ftputil 4.0.0 is now available from
https://ftputil.sschwarzer.net/download and
https://pypi.org/project/ftputil/


Changes since the last stable release 3.4
-----------------------------------------

Backward-incompatible changes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This ftputil version isn't fully backward-compatible with the previous
version. The backward-incompatible changes are:

- Python 2 is no longer supported.

- The minimum supported Python 3 version is 3.6.

- By default, time stamps in directory listings coming from the server
  are now assumed to be in UTC. Previously, listings were assumed to
  use the local time of the client. [1]

  Correspondingly, the definition of "time shift" has changed. The
  time shift is now defined as the time zone used in server listings
  (say, UTC+02:00) and UTC, in other words, the time shift now is the
  time zone offset applied in the server listings. In earlier ftputil
  versions, the time shift was defined as "time used in server
  listings" minus "local client time."

- The flag `use_list_a_option` of `FTPHost` instances is now set to
  `False` by default. This option was intended to make life easier for
  users, but turned out to be problematic [2].

- As in `os.makedirs`, `FTPHost.makedirs` now supports the `exist_ok`
  flag and uses the default of `False`. You can get the behavior of
  ftputil 3.x by passing `exist_ok=True`. [3]

If you need to use Python versions before 3.6, please use the previous
stable ftputil version 3.4.


Other changes
~~~~~~~~~~~~~

- Functions and methods which used to accept only `str` or `bytes`
  paths now _also_ accept `PathLike` objects [4, 5].

- Clear the stat cache when setting a new time shift value. [6]

- ftputil now officially follows semantic versioning (SemVer) [7].
  Actually ftputil has been following semantic versioning since a long
  time (probably since version 2.0 in 2004), but it was never
  explicitly guaranteed and new major versions were named x.0 instead
  of x.0.0 and new minor versions x.y instead of x.y.0.

- Internal changes: The tests were moved to pytest. The old mocking
  approach was replaced by a "scripted session" approach.


What is ftputil?
----------------

ftputil is a high-level FTP client library for the Python programming
language. ftputil implements a virtual file system for accessing FTP
servers, that is, it can generate file-like objects for remote files.
The library supports many functions similar to those in the `os`,
`os.path` and `shutil` modules. ftputil has convenience functions for
conditional uploads and downloads, and handles FTP clients and servers
in different timezones.
