Another Python SQLite wrapper

APSW stands for Another Python SQLite Wrapper. APSW supports CPython 3.8 onwards.

About

APSW lets you get the most out of the SQLite embedded relational database engine from Python, and the most out of Python from SQLite. APSW glues together the complete SQLite C API and Python's C API, staying up to date with both SQLite and Python.

It is recommended to use the builtin sqlite3 module if you want SQLite to appear interchangeable with the other database drivers.

Use APSW when you want to use SQLite fully, and have an improved developer experience. The documentation has a section on the differences between APSW and sqlite3.

apsw's Issues

Allow derived cursors

From rogerbinns on March 03, 2009 22:54:57

It should be possible to make derived cursors by passing the class to the
Connection.cursor() method. Check interaction with weakrefs and close
calls. fetchall may also need to use virtual step.

Example code:

class foo: pass

con=apsw.Connection("...")
cur=con.cursor(foo)

Original issue: http://code.google.com/p/apsw/issues/detail?id=43

Connection should have informational attributes

From rogerbinns on November 22, 2008 19:57:12

The Connection object should have some attributes with useful information.
This could include:

• The filename
• Open flags (read only etc)
• VFS name

UPDATE during SELECT

From [email protected] on June 08, 2009 11:20:52

In http://apsw.googlecode.com/svn/publish/cursor.html it says that the
preferred way to do changes to a database is this one:

| You can also get all the rows immediately by filling in a list:
|
| rows=list( cursor.execute("select * from example") )
| for row in rows:
| cursor.execute("insert ...")
|
| This last approach is recommended since you don’t have to worry
| about the database changing while doing the select.

From this I understand that changing the database (even if using a
different cursor) may mess with the result set of the running query.

However, when I tried to test this behaviour (try attached testcase) it
seems that the result set is not affected.

Unfortunately I also could not find any information about the expected
behavior in this situation on the SQLite website.

Do you have any information on which behaviour I can rely on? I would
rather avoid having te fetch the entire result set into a list, both for
performance and style reasons.

Check PyObject_AsReadBuffer usage for unicode

From rogerbinns on September 21, 2008 03:10:13

Python 2.5 accepts unicode objects for buffers which is usually not what I
intended. Each usage should be checked to make sure that unicode is not
accepted if what I really wanted was bytes only

Allow customization of cursor objects

From pavlos.casa on November 26, 2008 05:30:27

Would be a good idea to allow customization of the standard cursor object.

Perhaps apsw.Connection can be extended to receive a custom cursor class as
a parameter and if provided, the cursor return is an instance of the custom
class. for that to work well the cursor object should allow subclassing in
python.

here is a typical use case:

cursor with fetchall

class MyCursor(apsw.Cursor):

def fetchall(self):
return [i for in in self]

con = apsw.Connection(custom_cursor = MyCursor)

Add Py_TPFLAGS_HAVE_VERSION_TAG

From rogerbinns on October 02, 2008 18:22:10

The tpflag allows Python 2.6+ to have an attribute cache but causes issues
if direct manipulation of the object dict happens from C. I don't do that
so it should be safe to add. See also http://bugs.python.org/issue1878

From rogerbinns on April 09, 2008 01:11:45

Break apsw.c into pieces, use sphinx for doc

From rogerbinns on September 01, 2008 16:28:09

Google chokes on individual files larget than 200kb. It is also harder to
find code or potentially disable it. So split the C code into several
files (eg connection.c, cursor.c, vtable.c, vfs.c) and then have apsw.c

include them all.

Also investigate using sphinx for doc and folding the various API doc into
comments above the corresponding C implementation.

setbusytimeout doesn't wait

From [email protected] on June 09, 2009 16:13:32

I have a testcase (which is still too long to attach it here) which fails
with the following output:

Traceback (most recent call last):
File "./tests/02_fs_api.py", line 43, in tearDown
self.server.close()
File "/home/nikratio/lib/EclipseWorkspace/s3ql/s3ql/fs.py", line 597, in
close
cur.cursor.execute("VACUUM")
File "apsw.c", line 4238, in resetcursor
BusyError: BusyError: database is locked

However, line 597 in fs.py actually looks like this:

    cur.cursor.getconnection().setbusytimeout(50000)
    cur.cursor.execute("VACUUM")

so it seems to me that the tests should take at least 50 seconds to run.
But it aborts in a fraction of a second.

I know that this behaviour is probably not the cause of my real bug
(because manually adding a sleep(50) doesn't fix it), but I wonder if it
may somehow be possible that apsw thinks the database is locked (and
therefore returns the exception) while it actually isn't (which is why it
doesn't wait).

Error on attempting to use the same connection in multiple threads.

From amicitas on October 24, 2008 13:05:39

What steps will reproduce the problem? 1. Attempt to simultaneously use the same connection in two threads. What is the expected output? What do you see instead? It would be very nice if an error was raised if this is attempted. At this
point the application just hangs with no error output. What version of the product are you using? On what operating system? apsw 3.5.9- r2 , python 2.5 & 2.6, windows xp sp3 Please provide any additional information below. The documentation does clearly state that a connection cannot be used in
more than one thread. If it is attempted the application just hangs. Both
threads stop as well as the main program. I would be nice if an error was
thrown as it is if the cursor is used in two threads.

Sub-optimal error message, different behaviour for Cursor.execute with/without bindings

From basti1302 on April 02, 2008 03:10:38

The method Cursor.executes seems to behaves differently when used with the
optional bindings argument compared to using it without the bindings
argument. More specifically, the error message when trying to insert a
NULL value into an PRIMARY KEY NOT NULL column (without autoincrement in
place) is different. The error message in the first case (with bindings)
is less helpful than it could be. I'm not sure if this is intended
behaviour, IMHO it's a bit confusing.

The following program demonstrates the difference:

import apsw

print "apsw.apswversion(): " + apsw.apswversion()
print "apsw.sqlitelibversion(): " + apsw.sqlitelibversion()

connection = apsw.Connection("dbfile")
cursor = connection.cursor()

try:
print "test 1"
try:
cursor.execute("DROP TABLE A_TABLE")
cursor.execute("CREATE TABLE A_TABLE (ID ABC PRIMARY KEY NOT NULL,
SOME_VALUE TEXT)")
cursor.execute("INSERT INTO A_TABLE VALUES (NULL, 'Foobar')")
except Exception, e:
print e

print "test 2"
try:
    cursor.execute("DROP TABLE A_TABLE")
    cursor.execute("CREATE TABLE A_TABLE (ID ABC PRIMARY KEY NOT NULL, 

SOME_VALUE TEXT)")
cursor.execute("INSERT INTO A_TABLE VALUES (NULL, ?)", ("Foobar",))
except Exception, e:
print e

finally:
connection.close()

The output of this program is:

apsw.apswversion(): 3.3.13- r1 apsw.sqlitelibversion(): 3.3.13
test 1
ConstraintError: A_TABLE.ID may not be NULL
test 2
ConstraintError: not an error

In both tests, a table is created with an ID column and a value column.
The column affinity of ID is set to ABC (which is a nonsense value), so it
defaults to NUMERIC, afaik. The point is that it the column is not INTEGER
PRIMARY KEY NOT NULL, so we have no autoincrement, as specified in the
sqlite docs. Because of that, inserting NULL should be illegal.

In test 1, the exception raised is "ConstraintError: A_TABLE.ID may not be
NULL", as expected. However, in test 2, the exception is "ConstraintError:
not an error" which sounds a bit paradox to me.

Note 1: This is on Windows 2000, Python 2.5

Note 2: This may or may not be related to this bug report: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=456500 but I don't really know how this Debian package bug reports relate to apsw
bug reports.

BLOB columns are converted to/from UTF8

I want to store short binary strings in a table. Therefore I do not want to

Deal with forking

From rogerbinns on April 05, 2008 03:37:25

See last paragraph of http://www.sqlite.org/faq.html#q6 Currently I can't find any way of catching interpretter forks. The
PyOS_AfterFork method is called but doesn't provide any way to hook into it.

A possible solution is to check the pid in calls and if different from when
the object was allocated, mark it and all related cursors/blobs as closed
(which will leak memory but can't be avoided).

Update the doc for Connection.close() to mention it would be a good idea to
call it before forking.

What happens if

1. I prepare and execute a select statement
2. I retrieve a couple of rows
3. I execute a new query that would change the result of the
   query in 1

On the same connection, I assume.

Yes.

1. I continue to retrieve the results of 1)

Will I get the results as if step 3 hasn't happened, is the result
undefined, or will my result set somehow be updated?

You may or may not see the changes introduced by step 3. E.g. if
step 3 updates a record that you've already visited, you naturally
won't visit it again and thus won't see the changes. But if it
updates a record you haven't visited yet, when you get to it you
will see the new data.

This doesn't seem right when I test it. "numbers" is a table with one
column containing the numbers 1 to 10. When using the python
interface:

import apsw
conn=apsw.Connection("data")
cursor = conn.cursor()
res = cursor.execute("select * from numbers")
res.next()
(1,)
res.next()
(2,)
res.next()
(3,)
cursor.execute("delete from numbers where no=5")
res.next()
Traceback (most recent call last):
File "", line 1, in
StopIteration

So as soon as I make a change in the database, I do not get any more
results. If I understood you correctly, I should have gotten (4,)
instead.

Is this a bug?

It is probably a bug (or a design decision) in the apsw wrapper. The
following program produces the expected output using the C API functions.

include <stdio.h>

include <stdlib.h>

include <sqlite3.h>

using namespace std;

int main(int argc, char argv[])
{
sqlite3 db;

 sqlite3_open("test.db3", &db);
 sqlite3_exec(db, "create table numbers (n integer)", 0, 0, 0);

 char sql[100];
 for (int i = 1; i <=10; ++i) {
     sprintf(sql, "insert into numbers values(&#37;d)", i);
     sqlite3_exec(db, sql, 0, 0, 0);
 }

 sqlite3_stmt* s;
 sqlite3_prepare(db, "select * from numbers", -1, &s, 0);

 sqlite3_step(s);
 printf("&#37;d\n", sqlite3_column_int(s, 0));
 sqlite3_step(s);
 printf("&#37;d\n", sqlite3_column_int(s, 0));
 sqlite3_step(s);
 printf("&#37;d\n", sqlite3_column_int(s, 0));

 sqlite3_exec(db, "delete from numbers where n = 5", 0, 0, 0);

 sqlite3_step(s);
 printf("&#37;d\n", sqlite3_column_int(s, 0));
 sqlite3_step(s);
 printf("&#37;d\n", sqlite3_column_int(s, 0));
 sqlite3_step(s);
 printf("&#37;d\n", sqlite3_column_int(s, 0));

 sqlite3_finalize(s);
 sqlite3_close(db);

 system("PAUSE");
 return EXIT_SUCCESS;

}

Update setup.py to look for --download-sqlite in sys.argv and then
automatically grab the amalgamation from http://sqlite.org/download.html parse the html to find sqlite-amalgamation-3_[0-9]+_[0-9]+.zip and grab it.

SQLITE_MAX_* constants not part of SQLite API

From rogerbinns on June 30, 2008 14:40:43

See http://www.sqlite.org/cvstrac/tktview?tn=3195 They should either be removed or made conditional #ifdef

Blob.read behaviour and documentation inconsistent

From rogerbinns on June 12, 2009 12:03:34

Need to ensure the code and documentation match the builtin file type
especially in the case of end of file being reached.

APSW would crash when used with Stackless Python

From nirvana117 on March 22, 2008 03:38:18

What steps will reproduce the problem? 1. import apsw
2. apsw.Connection(":memory:") What version of the product are you using? On what operating system? apsw-3.3.13- r1 , Stackless_Python_2.5.2, on windows_xp_sp2 or 2003_sp2. Please provide any additional information below. I have tested pysqlite and apsw, but only apsw would crash stackless
python, not pysqlite. So I thought there may be some problem in apsw.

Allow setting tracers on Connection

From rogerbinns on November 22, 2008 19:58:08

You should be able to set exec/row tracers on the Connection. These should
be used by the cursors unless they explicitly have one set (or None to
disable).

Allow apsw to be used as an extension

From rogerbinns on September 25, 2008 15:52:02

An example use case is for the filesource from the example to work in the
SQLite command line interpreter.

There are a number of parts needed to get this to work:

• Compile apsw using sqlite3ext.h although it is missing several functions
• Work out which python file to load as there are no ways to pass
  arguments to the extension loading routine
• Probably hook into all database connections using sqlite3_auto_extension
