NEWS
1
psycopg news for 1.1.15
2
-----------------------
3
4
* Interval typecasting eventually-eventually works the Right Way (TM).
5
6
* Fixed two bad memory leaks in QuotedString and Binary objects.
7
8
* Reverted change on rowcount attribute, now it is always set to the real
9
number of affected columns.
10
11
psycopg news for 1.1.14
12
-----------------------
13
14
* Interval typecasting eventually works the Right Way (TM).
15
16
* ZPsycopgDA now support unicode strings and different backend encodings.
17
18
* ZPsycopgDA accept query data as an extra parameter to execute() (but
19
still no way to give it extra data from inside a ZSQL Method.)
20
21
* Better DBAPI-2.0 compliance (rowcount attribute and argument passing.)
22
23
* Now builds on Fedora Core 2 (but remember that the real psycopg
24
aficionado runs on Debian ;-P )
25
26
* COPY FROM raise an exception and return usefull information on error.
27
28
psycopg news for 1.1.13
29
-----------------------
30
31
* ZPsycopgDA works again.
32
33
psycopg news for 1.1.12
34
-----------------------
35
36
* Fixed nasty segfault/deadlock in switch_isolation_level.
37
38
* Now the PostgreSQL TIME type is correctly converted to a DateTimeDelta
39
instead of a DateTime. This is much better because you can now add two
40
times and a time and a date.
41
42
* Added an "sslmode" parameter (look at PostgreSQL documentation for
43
possible values.)
44
45
* .execute() now rise the right exception if called with a wrong
46
tuple/dict. Also, %% in queries does not raise an exception anymore.
47
48
* Updated RPM specs (thanks to Mark McClain we now have updated RPMs on
49
initd.org too.)
50
51
psycopg news for 1.1.11
52
-----------------------
53
54
* a modern autoconf is now needed to build psycopg.
55
56
* now an error during commit or rollback is correctly reported by raising
57
an exception.
58
59
* when the libpq protocol 3.0 is available, psycopg uses a smater method
60
to determine exception type (unfortunately the old string compare method
61
is still neede for postgresql <= 7.3.x.)
62
63
* plugged a memory leak in copy_from().
64
65
* where did the news for 1.1.10 go?
66
67
psycopg news for 1.1.9
68
----------------------
69
70
* psycopg distribution now includes the GeoTypes package by Richard Taylor
71
(QinetiQ Plc)!
72
73
* Problems with sequences and mappings non correctly used in .execute()
74
should be gone (mogrification code completely rewritten.) Many thanks
75
to Richard Taylor and Vsevolod Lobko that helped by testing the "pre"
76
releases.
77
78
* no more libpq 7.1.x linking problems related to PQfreeNotify.
79
80
psycopg news for 1.1.7
81
----------------------
82
83
* added notifies and fileno methods to cursor objects.
84
85
* now execute accept any object that defined __getitem__ and not only
86
dictionaries.
87
88
* little fix in ZPsycopgDA, should work with Zope 2.7.
89
90
psycopg news for 1.1.6
91
----------------------
92
93
* cursor objects now have the .scroll() method.
94
95
* NUL characters in strings are discarded in quoting; use a Binary object if
96
you need strings with embedded NULs.
97
98
* Fixed another MT problem in .execute().
99
100
psycopg news for 1.1.5
101
----------------------
102
103
* ZPsycopgDA now rollback before raising an exception; should be a backward
104
compatible change for people that really want to continue executing queries
105
after an exception.
106
107
* fixed problem with dictionary mogrification (i.e., specifying the same key
108
multiple times and having the None value in the dict should work now.)
109
110
* fixed keeper status trashing problem: no more psycopg stuck in transaction
111
(maybe this will also solve ZPsycopgDA problems: will see...)
112
113
* now copy_from and copy_to can be passed instances of classes with "readline"
114
and "write" methods and not only file instances.
115
116
psycopg news for 1.1.4
117
----------------------
118
119
* Fixed various memory leak problems.
120
121
* Implemented "statusmessage" attribute on cursors.
122
123
psycopg news for 1.1.3
124
----------------------
125
126
* Fixed problem with psycopg always reporting IntegrityError.
127
128
* Fixed segfault in debug statements.
129
130
* Now Python GIL is unlocked during PQconnectdb() calls (better
131
multithreading.)
132
133
psycopg news for 1.1.2
134
----------------------
135
136
* Skipped version 1.1.1 (never released 'cause of a cvs tag error)
137
138
* Much better cursor.description fields (many thanks to William K. Volkman)
139
140
* psycopg.connect() now takes keyword parameters for host, dbname, port,
141
user and password (they are all strings, even "port".)
142
143
* connection.set_isolation_level() implemented to help switching from default
144
isolation to other levels supported by PostgreSQL. [autocommit now simply
145
does a set_isolation_level(0)]
146
147
* Implemented .lastrowid attribute for cursors.
148
149
* Now psycopg should build on win32/cygwin, thank to Hajime Nakagami patches.
150
151
* Includes every fix from 1.0.x up to 1.0.15.1:
152
153
- Fixed connection-stay-open-when-i-do-conn.close() bug.
154
- Better DBAPI-2.0 compliance for setinputsizes and setoutputsize methods.
155
- Better support for build on MacOS X.
156
- Fixed problem with formats in string mogrification.
157
- Fixed other miscellaneous buglets in Zope Adapter.
158
- Fixed small memory leak in .fetchXXX() methods.
159
- Fixed serialization problem in ZPsycopgDA reported by Dieter Maurer.

----------------------
203
204
* fixed problem with connection left in invalid state by applying
205

psycopg news for 1.0.7
221
----------------------
222
223
* Fixed little bugs in type management (infinity problems and the
224
TIMESTAMPTZ type) and Zope import. Better configure script.
225
226
* Now psycopg really close the physical connection to PostgreSQL on
227
connection .close().
228
229
psycopg news for 1.0.5
230
----------------------
231
232
* Applied a little patch to make table browser in zope show system tables
233

236
237
psycopg news for 1.0.4
238

241
242
* Table browsing works again.
243
244
psycopg news for 1.0.3
245
----------------------
246
247
* bugfix for b0rken ZPsycopgDA in 1.0.2.
248
249
psycopg news for 1.0.2
250
----------------------
251
252
* Fixed problem with incorrect interpretation of hundredths of a second.
253
254
psycopg news for 1.0.1
255
----------------------
256
257
* fixed two little memory leaks, see ChangeLog for details.
258
259
* fixed problem with garbled passwords when using crypt autentication.
260
261
psycopg news for 1.0
262
--------------------
263
264
* added regression tests, first result is much better conversion of date and
265
time types.
266
267
* fixed last know segfault (psycopg runs stable for a lot of people now.)
268
269
* psycopg compile and run on FreeBSD and MacOS X.
270
271
* much better binary objects, they use less memory and quoting is faster,
272
thank to the new, smarter memory allocator.
273
274
* fixed all reported buglets (mostly dbapi and type-system related.)
275
276
* hey, this is one-dot-oh!
277
278
* the following features are missing from psycopg 1.0 and will be added when
279
we have a little more time (i.e., there will be no _feature_ releases after
280
1.0, only bugfixes):
281
282
- documentation is incomplete (we are slowly writing it, track CVS if you
283
want up-to-date docs)
284
285
- dbapi-2.0 testsuite is incomplete (need to move code to the unittest
286
framework)
287
288
- psycopg needs a full suite of regression tests to be sure we don't break
289
things while implementing new features (i think we'll add them _while_
290
writing new features :)
291
292
psycopg news for 0.99.7
293
-----------------------
294
295
* time intervals are correctly recognized and converted into DateTimeInterval
296
objects.
297
298
* almost complete (bugs apart) DBAPI-2.0 support. switched psycopg to use
299
QuotedString for every string passed as a bound argument. Binary now works
300
(but still consumes lots of memory).
301
302
* added doc/ to hold documentation.
303
304
* added lastoid() method to cursor objects, to retrieve the OID of the last
305
inserted row.
306
307
psycopg news for 0.99.4
308
-----------------------
309
310
* psycopg is approaching 1.0, so only DBAPI compliance patches and bug fixes
311
are getting in.
312
313
* added Binary and QuotedString objects. note that sometime before 1.0 we'll
314
switch turn every string passed to psycopg into a QuotedString, possibily
315
breaking Zope compatibility and old scripts doing their own quoting.
316
317
psycopg news for 0.5.x
318
----------------------
319
320
* this is the development branch, if you want stability, stick with 0.4.6.
321
322
* added pthread locks so that different threads (cursors) can use the same
323
postgres connection (this was done *only* to respect the dbapi on cursor
324
isolation.)
325
326
* now the default for the .cursor() method is to associate every cursor to
327
the same physical connection, to avoid isolation (as the DBAPI-2.0 specify),
328
you can change that by calling the .serialize() method on the connection and
329
giving it 0 as the argument, e.g., "o.serialize(0)".
330
331
psycopg news for 0.4.1
332
----------------------
333
334
* autocommit mode is now supported on cursors and connections.
335
336
psycopg news for 0.4
337
--------------------
338
339
* implemented all the remaining DBAPI-2.0 type singletons (DATETIME and
340
BINARY included)
341
342
psycopg news for 0.3
343
--------------------
344
345
* threading problems resolved
346
347
* added type casting from postgres to python (the user can now specify
348
its own casting objects, the default singletons NUMBER and STRING are
349
included [and act as default cast objects] plus INTEGER and FLOAT as
350
an extension to the DBAPI-2.0.)
351
investigate the code in examples/usercast_test.py to understand how to
352
add your own types...
353
354
* beginning of the Zope Database Adapter: give it a try even it it is
355
broken!
1
What's new in psycopg 1.99.10
2
-----------------------------
3
4
* The adapt() function now fully supports the adaptation protocol
5
described in PEP 246. Note that the adapters registry now is indexed
6
by (type, protocol) and not by type alone. Change your adapters
7
accordingly.
8
9
* More configuration options moved from setup.py to setup.cfg.
10
11
* Fixed two memory leaks: one in cursor deallocation and one in row
12
fetching (.fetchXXX() methods.)
13
14
What's new in psycopg 1.99.9
15
----------------------------
16
17
* Added simple pooling code (psycopg.pool module); see the reworked
18
examples/threads.py for example code.
19
20
* Added DECIMAL typecaster to convert postgresql DECIMAL and NUMERIC
21
types (i.e, all types with an OID of NUMERICOID.) Note that the
22
DECIMAL typecaster does not set scale and precision on the created
23
objects but uses Python defaults.
24
25
* ZPsycopgDA back in and working using the new pooling code.
26
27
* Isn't that enough? :)
28
29
What's new in psycopg 1.99.8
30
----------------------------
31
32
* added support for UNICODE queries.
33
34
* added UNICODE typecaster; to activate it just do:
35
36
psycopg.extensions.register_type(psycopg.extensions.UNICODE)
37
38
Note that the UNICODE typecaster override the STRING one, so it is
39
not activated by default.
40
41
* cursors now really support the iterator protocol.
42
43
* solved the rounding errors in time conversions.
44
45
* now cursors support .fileno() and .isready() methods, to be used in
46
select() calls.
47
48
* .copy_from() and .copy_in() methods are back in (still using the old
49
protocol, will be updated to use new one in next releasae.)
50
51
* fixed memory corruption bug reported on win32 platform.
52
53
What's new in psycopg 1.99.7
54
----------------------------
55
56
* added support for tuple factories in cursor objects (removed factory
57
argument in favor of a .tuple_factory attribute on the cursor object);
58
see the new module psycopg.extras for a cursor (DictCursor) that
59
return rows as objects that support indexing both by position and
60
column name.
61
62
* added support for tzinfo objects in datetime.timestamp objects: the
63
PostgreSQL type "timestamp with time zone" is converted to
64
datetime.timestamp with a FixedOffsetTimezone initialized as necessary.
65
66
What's new in psycopg 1.99.6
67
----------------------------
68
69
* sslmode parameter from 1.1.x
70
71
* various datetime conversion improvements.
72
73
* now psycopg should compile without mx or without native datetime
74
(not both, obviously.)
75
76
* included various win32/MSVC fixes (pthread.h changes, winsock2
77
library, include path in setup.py, etc.)
78
79
* ported interval fixes from 1.1.14/1.1.15.
80
81
* the last query executed by a cursor is now available in the
82
.query attribute.
83
84
* conversion of unicode strings to backend encoding now uses a table
85
(that still need to be filled.)
86
87
* cursors now have a .mogrify() method that return the query string
88
instead of executing it.
89
90
* connection objects now have a .dsn read-only attribute that holds the
91
connection string.
92
93
* moved psycopg C module to _psycopg and made psycopg a python module:
94
this allows for a neat separation of DBAPI-2.0 functionality and psycopg
95
extensions; the psycopg namespace will be also used to provide
96
python-only extensions (like the pooling code, some ZPsycopgDA support
97
functions and the like.)
98
99
What's new in psycopg 1.99.3
100
----------------------------
101
102
* added support for python 2.3 datetime types (both ways) and made datetime
103
the default set of typecasters when available.
104
105
* added example: dt.py.
106
107
What's new in psycopg 1.99.3
108
----------------------------
109
110
* initial working support for unicode bound variables: UTF-8 and latin-1
111
backend encodings are natively supported (and the encoding.py example even
112
works!)
113
114
* added .set_client_encoding() method on the connection object.
115
116
* added examples: encoding.py, binary.py, lastrowid.py.
117
118
What's new in psycopg 1.99.2
119
----------------------------
120
121
* better typecasting:
122
- DateTimeDelta used for postgresql TIME (merge from 1.1)
123
- BYTEA now is converted to a real buffer object, not to a string
124
125
* buffer objects are now adapted into Binary objects automatically.
126
127
* ported scroll method from 1.1 (DBAPI-2.0 extension for cursors)
128
129
* initial support for some DBAPI-2.0 extensions:
130
- .rownumber attribute for cursors
131
- .connection attribute for cursors
132
- .next() and .__iter__() methods to have cursors support the iterator
133
protocol
134
- all exception objects are exported to the connection object
135
136
What's new in psycopg 1.99.1
137
----------------------------
138
139
* implemented microprotocols to adapt arbitrary types to the interface used by
140
psycopg to bind variables in execute;
141
142
* moved qstring, pboolean and mxdatetime to the new adapter layout (binary is
143
still missing; python 2.3 datetime needs to be written).
144
145
146
What's new in psycopg 1.99.0
147
----------------------------
148
149
* reorganized the whole source tree;
150
151
* async core is in place;
152
153
* splitted QuotedString objects from mx stuff;
154
155
* dropped autotools and moved to pythonic setup.py (needs work.)
