In the first place Git is a key-value storage system. The keys are called
OIDs, for Object id, and the values stored are called Objects.
In the first place Git is a key-value storage system. The values stored are
called *objects*, there are four types (commits, trees, blobs and tags),
for each type pygit2 has a Python class::
Oids
=================
The oid is the `SHA-1 <http://en.wikipedia.org/wiki/SHA-1>`_ hash of an
object. It is 20 bytes long:
- When we represent an oid as a 20 bytes Python string, we say it is a raw
oid.
- When we represent an oid as a 40 chars Python string, we sayt it is a hex
oid.
However, most of the time we will use the Oid type. We can explicetly create
an Oid object from its raw or hexadecimal form::
>>> hex = "cff3ceaefc955f0dbe1957017db181bc49913781"
>>> oid1 = Oid(hex=hex)
>>> from binascii import unhexlify
>>> raw = unhexlify(hex)
>>> oid2 = Oid(raw=raw)
>>> print oid1 == oid2
True
And in the opposite direction, we can get the raw or hexadecimal form from
an Oid object:
.. autoattribute:: pygit2.Oid.raw
.. autoattribute:: pygit2.Oid.hex
The Oid type supports:
- rich comparisons, not just for equality, also: lesser-than, lesser-or-equal,
etc.
- hashing, so Oid objects can be used as keys in a dictionary
Python 2 and Python 3
---------------------
There is a difference on how the library handles hex oids, depending on
whether we are using Python 2 or 3.
- In Python 2, we can represent an hexadecimal oid using a bytes string
(``str``) or a text string (``unicode``)
- In Python 3, hexadecimal oids can only be represented using unicode
strings.
Objects
=================
There are four types (commits, trees, blobs and tags), for each type pygit2
has a Python class::
>>> # Show commits and trees
>>> commit
