iron-io/iron_core_python

iron_core_python

iron_core_python is a collection of common functions for working with the RESTful APIs that we build at Iron.io from Python.

It Is

• Service-agnostic
• Pip- and easy_install-installable
• Well documented

It Is Not

• An API wrapper. Those are specific to each service, and you can generally find them by checking the documentation for the service.
• A place for service-specific code. This is only meant to handle the basic, common interaction.

Installation

You can use pip or easy_install to install the release version. If you'd like to work with a development or beta version, retrieve the files from Github and run python setup.py install from the root directory.

iron_core_python's Issues

error messages get swallowed

iron_core_python/iron_core.py

Lines 239 to 252 in f09a160

	r = self._doRequest(url, method, body, headers)
	retry_http_codes = [503, 504]
	if r.status_code in retry_http_codes and retry:
	tries = 5
	delay = .5
	backoff = 2
	while r.status_code in retry_http_codes and tries > 0:
	tries -= 1
	time.sleep(delay)
	delay *= backoff
	r = self._doRequest(url, method, body, headers)
	r.raise_for_status()

The actual error message is in response.text and can't be accessed after the raise_for_status anymore. It's hard to know on application level what went wrong if the error is just "400 bad request". It would be good if the actual error message would be part of the exception message.

After hacking the library I found out that I actually got the error message {"msg":"Message must be no more than 64k"} from ironmq. I was spending have the day searching why my request is not working.

'IronClient' object has no attribute 'path_prefix'

Hello,

We use the iron mq python client installed via pip, and it's been failing recently with:

  File "/home/travis/virtualenv/python2.7.8/lib/python2.7/site-packages/iron_mq.py", line 252, in __init__
    version=IronMQ.VERSION, product="iron_mq", **kwargs)
  File "/home/travis/virtualenv/python2.7.8/lib/python2.7/site-packages/iron_core.py", line 175, in __init__
    self.base_url = "%s://%s%s/%s/" % (self.protocol, self.host, self.path_prefix, self.api_version)
AttributeError: 'IronClient' object has no attribute 'path_prefix'

I noticed that path_prefix was added recently to iron_core and it seems like it might not be set in this if statement on line 175:

if self.protocol == "https" and self.port == 443:
    self.base_url = "%s://%s%s/%s/" % (self.protocol, self.host, self.path_prefix, self.api_version)

Should be available on PyPI

When I python setup.py develop a package that has IronMQ in its dependencies, it fails because it can't find iron-core on PyPI.

Also, the link in README.md points to http://pypi.python.org/pypi/iron_core_python. I think it should be http://pypi.python.org/pypi/iron_core, because the dependency in iron-mq is iron_core, not iron_core_python.

Building fails with setuptools >= 58

Setuptools 58.0 (4 Oct 2021) deprecated use_2to3, so the package no longer builds correctly.

Considering Python 2 has been EOL for a long, long time it would probably be worth it to 2to3/modernize this package to target e.g. Python 3.6+ only, and configure setup accordingly?

App Engine: ImportError: No module named pwd

Error when running on App Engine Python 1.7

File "/base/data/home/apps/s~-tools-hrd/2.360644688465653543/iron_mq.py", line 22, in init

ImportError: No module named pwd

pwd module is not available on App Engine VM.

It works just fine on the local App Engine dev env. I guess it is a App Engine problem, but maybe you can solve this so other developers do not have to bother.
