Previously all keys starting with an underscore were ignored (so changes
to _created wouldn't count as "different"), but this clashes with saving
Markdown output to _xxx_html keys.
Note that undeleting files cannot be done via Eve, as it doesn't support
PATCHing collections. Instead, direct MongoDB modification is used to set
_deleted=False and provide new _etag and _updated values.
Hashing of string object doesn't work. Also added a deprecation warning
that pillar.api.utils.gravatar should be used; pillar.web.utils.gravatar
is just a copy.
These changes mostly revolve around the change in ObjectId constructor
when running on Python 3.6. Where on 2.7 the constructor would accept
12- and 24-byte strings, now only 12-byte bytes and 24-character strings
are accepted. Good thing, but required some changes in our code.
Other changes include hashing of strings, which isn't supported, so they
are converted to bytes first, and sometimes converted back afterwards.
The 'manual fixups' are:
- incorrect use of dict.items() where dict.iteritems() was meant; this
results in list(dict.items()), which I changed to dict.items().
- removal of 'from __future__ import' lines, which 2to3 changes into
empty lines; I removed the empty lines.
It was used in an experiment in Flamenco as an alternative to JSON; it
might still be used in the future if BSON turns out to be significantly
faster to generate.
Refactor of pillar-server and pillar-web into a single python package. This
simplifies the overall architecture of pillar applications.
