- Include a blank line between the signature line and the description
(Guido sez).
- Don't include "-> None" for API functions that always return None
because they don't have a meaningful return value.
These built-in functions are replaced by their (now callable) type:
slice()
buffer()
and these types can also be called (but have no built-in named
function named after them)
classobj (type name used to be "class")
code
function
instance
instancemethod (type name used to be "instance method")
The module "new" has been replaced with a small backward compatibility
placeholder in Python.
A large portion of the patch simply removes the new module from
various platform-specific build recipes. The following binary Mac
project files still have references to it:
Mac/Build/PythonCore.mcp
Mac/Build/PythonStandSmall.mcp
Mac/Build/PythonStandalone.mcp
[I've tweaked the code layout and the doc strings here and there, and
added a comment to types.py about StringTypes vs. basestring. --Guido]
library. Since multiple versions can be installed simultaneously, it's
crucial that you only select libraries and header files which are compatible
with each other. Version checking is done from highest version to lowest.
Building using version 1 of Berkeley DB is disabled by default because of
the hash file bugs people keep rediscovering. It can be enabled by
uncommenting a few lines in setup.py. Closes patch 553108.
that retries the connect() call in timeout mode so it can be shared
between connect() and connect_ex(), and needs only a single #ifdef.
The test for this was doing funky stuff I don't approve of,
so I removed it in favor of a simpler test. This allowed me
to implement a simpler, "purer" form of the timeout retry code.
Hopefully that's enough (if you want to be fancy, use non-blocking
mode and decode the errors yourself, like before).
- setblocking(0) and settimeout(0) are now equivalent, and ditto for
setblocking(1) and settimeout(None).
- Don't raise an exception from internal_select(); let the final call
report the error (this means you will get an EAGAIN error instead of
an ETIMEDOUT error -- I don't care).
- Move the select to inside the Py_{BEGIN,END}_ALLOW_THREADS brackets,
so other theads can run (this was a bug in the original code).
- Redid the retry logic in connect() and connect_ex() to avoid masking
errors. This probably doesn't work for Windows yet; I'll fix that
next. It may also fail on other platforms, depending on what
retrying a connect does; I need help with this.
- Get rid of the retry logic in accept(). I don't think it was needed
at all. But I may be wrong.
settimeout(). Already, settimeout() canceled non-blocking mode; now,
setblocking() also cancels the timeout. This is easier to document.
(XXX should settimeout(0) be an alias for setblocking(0)? They seem
to have roughly the same effect. Also, I'm not sure that the code in
connect() and accept() is correct in all cases. We'll sort this out
soon enough.)
not testing it -- apparently test_timeout.py doesn't test anything
useful):
In internal_select():
- The tv_usec part of the timeout for select() was calculated wrong.
- The first argument to select() was one too low.
- The sense of the direction argument to internal_select() was
inverted.
In PySocketSock_settimeout():
- The calls to internal_setblocking() were swapped.
Also, repaired some comments and fixed the test for the return value
of internal_select() in sendall -- this was in the original patch.
I've made considerable changes to Michael's code, specifically to use
the select() system call directly and to store the timeout as a C
double instead of a Python object; internally, -1.0 (or anything
negative) represents the None from the API.
I'm not 100% sure that all corner cases are covered correctly, so
please keep an eye on this. Next I'm going to try it Windows before
Tim complains.
No way is this a bugfix candidate. :-)
readline in all python versions is configured
to append a 'space' character for a successful
completion. But for almost all python expressions
'space' is not wanted (see coding conventions PEP 8).
For example if you have a function 'longfunction'
and you type 'longf<TAB>' you get 'longfunction '
as a completion. note the unwanted space at the
end.
The patch fixes this behaviour by setting readline's
append_character to '\0' which means don't append
anything. This doesn't work with readline < 2.1
(AFAIK nowadays readline2.2 is in good use).
An alternative approach would be to make the
append_character
accessable from python so that modules like
the rlcompleter.py can set it to '\0'.
[Ed.: I think expecting readline >= 2.2 is fine. If a completer wants
another character they can append that to the keyword in the list.]
[ 559250 ] more POSIX signal stuff
Adds support (and docs and tests and autoconfery) for posix signal
mask handling -- sigpending, sigprocmask and sigsuspend.
The old syntax suggested that a trailing comma was OK inside backticks,
but in fact (due to ideosyncrasies of pgen) it was not. Fix the grammar
to avoid the ambiguity. Fred: you may want to update the refman.
generations is now an array. This cleans up some code and makes it easy
to change the number of generations. Also, implemented a
gc_list_is_empty() function. This makes the logic a little clearer in
places. The performance impact of these changes should be negligible.
One functional change is that allocation/collection counters are always
zeroed at the start of a collection. This should fix SF bug #551915.
This change is too big for back-porting but the minimal patch on SF
looks good for a bugfix release.
Unicode objects are currently taken as binary data by the write()
method. This is not what Unicode users expect, nor what the
StringIO.py code does. Until somebody adds a way to specify binary or
text mode for cStringIO objects, change the format string to use "t#"
instead of "s#", so that it will request the "text buffer" version.
This will try the default encoding for Unicode objects.
This is *not* a 2.2 bugfix (since it *is* a semantic change).
