Change log for CommonPy

Version 1.13.0

Changes in this release:

  • HTTP code 422 is now more accurately returned as a ServiceFailure error instead of a NetworkFailure.

Version 1.12.4

Changes in this release:

  • Revise the retry algorithm in timed_request() again.
  • Make timed_request() print the response text in case of failures
  • Remove extra_requires from setup.py because it caused installation problems due to the syntax of the requirements file and I don't have patience for figuring out what setuptools needs this time.

Version 1.12.3

This release updates the version of the dateparser package in requirements.txt, to avoid a deprecation warning when using CommonPy's parsed_datetime(...) function.

Version 1.12.2

This release updates the versions of dependencies in requirements.txt.

Version 1.12.1

This version prevents certain exceptions from being buried and ignored, and improves the network failure retry algorithm.

Version 1.12.0

Additions in this release:

  • New function network in the network_utils module. It is a companion to net and takes the same arguments, but returns only one value (the response). If an error occurs, it raises the error as an exception. This makes it possible for callers to use network(...) in somewhat more Pythonic style than net(...), by wrapping the call to network(...) in try-except.

Changes in this release:

  • Removed slice from data_utils module because it shadows a Python built-in.
  • Fixed hostname in network_utils to be more general and not hardwire a test for http.
  • Fixed a bunch of flake8 warnings.

Version 1.11.0

Additions in this release:

  • New class CaseFoldSet, similar to CaseFoldDict but … a set.

Changes in this release:

  • Fixed a bug in the class documentation in the README.md file.
  • Added missing dependency for twine in requirements-dev
  • Now using lazy imports in more places, for faster load times.

Version 1.10.0

Changes in this release:

  • data_utils.flattened now outputs [] as the value of dict or mapping keys whose original values are an empty sequence (e.g., when the value of a dict key is []). Previously, it would output None as the value, which was an unexpected transformation of the input.

Bug fixes in this release:

  • Fixed a bug in data_utils.flattened that caused it to ignore the separator argument in some cases.
  • Fixed a missing import of freezegun in requirements-dev.txt.
  • Pin the imported version of regex 2022.3.2, because more recent versions cause calls to dateparser to encounter an error ("regex._regex_core.error: bad escape \d at position 7").

Version 1.9.5

The main functional change in this release is that error objects returned by net(...) will have error message bodies returned by network services, where possible.

Internally, there has been some refactoring of the Makefile and addition of things like GitHub template files.

Version 1.9.4

This release merely changes the version of httpx required by requirements.txt. No other changes.

Version 1.9.3

This version adds a missing internal function definition in download(...).

Version 1.9.2

This version changes pluralized so that it outputs 0 items instead of 0 item if the number of its argument has length 0.

Version 1.9.1

This version adds more test cases and splits out the requirements for testing/development into a separate requirements file, requirements-dev.txt.

Version 1.9.0

Changes in this release:

  • New exception ArgumentError.
  • net(...) makes slightly finer distinctions between ServiceFailure and NetworkFailure when it comes to addresses it can't connect to, and also raises ArgumentError in some cases such as passing a data keyword argument to a network get.
  • on_localhost(...) logs slightly better debug messages.
  • There are more test cases.
  • CITATION.cff has been corrected and no longer describes the wrong repository.

Version 1.8.2

This version merely changes a version dependency in requirements.txt. No other changes.

Version 1.8.1

Changes in this release:

  • At some point between versions 0.18 and 0.21.1 (current version), the httpx package changed the keyword argument named allow_redirects to follow_redirects, and our network_utils module functions broke as a result. This release updates network_utils to account for the change.
  • The requirements.txt file now pins most dependencies to a specific version, to avoid situations where getting a newer version of a package might break existing code.
  • The copyright year has been updated in various files.

Version 1.8.0

This version introduces the data_structures module, and a new class, CaseFoldDict.

Version 1.7.3

Changes in this release:

  • Fixed a missing f-string in an exception message, plus guarded a few more exception message strings with antiformat.
  • Added CITATION.cff file.
  • Updated the Makefile.

Version 1.7.2

Improve flattened to handle lists of dict keys.

Version 1.7.1

Add missing deprecation package to requirements.txt.

Version 1.7.0

Changes in this release:

  • Beginning with this release, the function reset() is deprecated in favor of the function reset_interrupts().
  • The function wait() resets the interrupt state before it begins waiting.

Version 1.6.3

This release fixes some unexpected failures in flattened(...).

Version 1.6.2

This release expands flattened(...) to deal with iterators and generators.

Version 1.6.1

This release fixes a bug in version 1.6.0.

Version 1.6.0

This release adds the new function flattened(...)

Version 1.5.0

This release adds the new function print_boxed(...).

Version 1.4.0

Changes in this version:

  • In net(...), in case of a connection error, don't do exponential back-off and retry. Retry only once and then give up, because connection errors often mean the server is not available and long waits are unhelpful to callers.
  • Change net(...) to not test if a network is available if the given destination address is on the local host. This prevents incorrectly returning NetworkFailure when the current host is detached from the network and the failure is actually a ServiceFailure (for example, if nothing is listening on the destination port on the local host).
  • Add new function on_localhost(...), for testing whether a given network location indicates the local host.

Note: the previous release, 1.3.10, should not have added new functions in a patch release – API changes should result in changing the minor release number, not merely the patch number. The previous release number was a mistake; it should have been 1.4.0, but since it wasn't, this release is 1.4.0.

Version 1.3.10

  • Add new functions download(...) and download_file(...).

Version 1.3.9

  • Don't import packages dateparser and validator_collection until actually necessary, to reduce application startup times.

Version 1.3.8

  • Fix problems on Windows involving the interrupt handler configured by config_interrupt(...). First, the internal function used did not have a signature that was correct for win32api.SetConsoleCtrlHandler on Windows. Second, the proper usage is to return a value, not raise an exception.

Version 1.3.7

  • Make relative(...) from file_utils more robust against a problem on Windows, in which Python's os.path.relpath generates an error when you try to use it on a network-mapped drive.

Version 1.3.6

  • Fix missing requirements.txt entry for pywin32 on Windows.

Version 1.3.5

  • Fix reference to missing function called by relative(...).

Version 1.3.4

  • Fix undefined exceptions in network_utils due to a missing import.

Version 1.3.3

  • Fix broken references to os.path functions.

Version 1.3.2

  • Add a check for a common mistake in parameters to net(...).

Version 1.3.1

  • Remove reference to HTTPX exception RequestBodyUnavailable, which no longer seems to exist in current versions of the HTTPX package.
  • Remove use of exception UserCancelled in network_utils.py, because its definition no longer existed elsewhere and on review it seemed unecessary in the context where it was used.

Version 1.3.0

  • Fixed issue #2: httpx Timeout needs a default value.
  • Bump the required version of httpx to 0.16.
  • Changed name filter_by_extension(...) to filtered_by_extension(...) to follow the style of other functions that return values.
  • Made trivial changes to the Makefile

Version 1.2.0

  • Added new function config_path(...)
  • Added more unit tests

Version 1.1.1

This version makes antiformat(...) more robust against values that are not strings, by applying str(...) to the incoming value.

Version 1.1.0

This version adds a start at a module of string utilities, and introduces antiformat(..): a function that will quote instances of { and } braces in a string so that the string can be passed safely to format.

Version 1.0.0

  • Rename a few functions to follow a more consistent naming convention.
  • Update requirements.txt file.
  • Add more documentation.
  • Call this a 1.0.0 release.

Version 0.0.7

  • Fix bug in filename_basename(...).
  • Improve plural(...) by using pluralize(...) from Boltons package.
  • Remove tests for removed module http_code.
  • Miscellaneous other minor fixes and tweaks.

Version 0.0.6

  • Add a new module, network_utils.
  • Start a collection of exceptions that may be returned by this package.
  • Add additional dependency requirements to requirements.txt.

Version 0.0.5

  • Add a new module, module_utils.
  • Add functions to the file_utils module.
  • The package __init__.py file no longer imports the individual modules. (Users are expected to use the approach from commonpy.modulename import functionname.)

Version 0.0.4

Changed the order of arguments to function config_interrupt in the interrupt module to be in a more convenient order for most use cases.

Version 0.0.3

This release adds the module interrupt. This module includes wait(...), a replacement for sleep(...) that is interruptible and works with multiple threads. It also provides methods to cause an interruption (including doing it by issuing a ^C to the program), check whether an interruption occurred, and other related operations.

Version 0.0.2

Fixed some issues with the README.md file and started adding some documentation about the functions.

Version 0.0.1

First release of various utilities developed for other Caltech Library projects over the last couple of years.
