Conntext 0.1.5

Rationale

• Each context being a single atomic process (“either all occur, or nothing occurs”)

• No manual commit (success), rollback (fail) or close (either)

• No ORM

Usage

Without Conntext,

conn = sqlite3.connect(":memory:")
try:
    cursor = conn.cursor()
    try:
        cursor.execute("CREATE TABLE person (name)")
        cursor.execute("INSERT INTO person (name) VALUES (?)",
                        ["microamp"])
    except Exception:
        raise
    finally:
        cursor.close()
except Exception:
    conn.rollback()
    raise
else:
    conn.commit()
finally:
    conn.close()

With Conntext,

from conntext import conntext

with conntext.conn(sqlite3.connect(":memory:")) as conn:
   with conntext.cursor(conn.cursor()) as cursor:
        cursor.execute("CREATE TABLE person (name)")
        cursor.execute("INSERT INTO person (name) VALUES (?)",
                       ["microamp"])
