[py3] Decode subprocess stdout in toolsutils.show_diffs() On Python 3, subprocess' pipes are bytes stream so we must decode them before printing. Without this change, diff of configuration files (e.g. all-in-one.conf as displayed upon instance upgrade) will rendered as a single line on Python 3.

[python3] make sure staticcontroller returns a bytes instance The ``publish()`` method of controller is supposed to return a bytes intsance. Returning a text_type instance will crash later on in the Pyramid response handler when assigning content to ``response.body`` (at least in Python3):: >>> from pyramid.response import Response >>> r = Response() >>> r.body = '' Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/adim/.virtualenvs/…/response.py", line 562, in _body__set raise TypeError(msg) TypeError: You cannot set Response.body to a text object (use Response.text)

[python3] use inspect.getfullargspec instead of inspect.getargspec The latter is now deprecated

[utils] Fixes compatiblity of QueryCache with expected dict interface QueryCache is expected to mimick the interface of the dict built-in. The current __iter__ implementation breaks this expectation by iterating over key, value pairs instead of only the keys. This changeset fixes this issue by changing the __iter__ implementation to iterate over the keys in the cache and providing an implementation of the items method with a contract identical to the dict build-in (return a copy of the key- value pairs within the dictionary as a list).

[test/statsd] add tests for cubicweb.statsd_logger

[utils] Implements __iter__ on QueryCache In order to be able to iterate over the currently cached queries (so that they may be inspected and invalidated), this changeset implementes __iter__ on QueryCache.

[utils] Added new get method to QueryCache The new get method enables the retrieval an item in the cache by specifying a default value so that in the absence of an item for the key, the default value is returned.

[test/rset] typo

[utils] Fixed issue in clearing QueryCache When trying to add an item in a full QueryCache, the cache tries to make room. It tries to list and remove non-permanent items with a transient counter (number of times it has been requested). However, there is a pathological case where items could be non-permanent but still not have a transient counter because they were added, but never requested. In some cases, the full cache could be flushed, including the permanent items. This changeset attempts to fix this issue by only dropping the non-permanent items that did not hav a transient counter.

[statsd] add a statsd_timethis context manager This context manager allows to report to statsd the execution time of any piece of code, without the need for it to be a function or a method, like:: def some_function(): do_stuff() with statsd_timethis('some context message'): do_that() ensure_this()

[test/rset] add tests for ResultSet.first() and .last() methods

[test/rset] flake8

[rset] update copyright

[rset] add convenient first() and last() methods on ResultSet These make life easier for the heavy user of the CW shell. Also aliases entities() with all(); so we end with a pretty consistant set: - .one() - .first() - .last() - .all()

[server] Fixed issue with the adapters cache of a cloned EditedEntity The adapters' cache of the entity within an EditedEntity used to be copied along the entity itself during a cloning operation of the EditedEntity. This raises an issue when the adapters' cache is not empty and contains cached values linking to transaction-specific data (or the transaction itself). This prevents the clone EditedEntity being used in a transaction outside the one that created it. This change resets the adapters' cache of the new copy so that no cached value remain. The new copy can then be used in a new transaction afterwards.
