Guido van Rossum 3cf5b1eef9 Get rid of most of the flags (in tp_flags) that keep track of various
variations of the type struct and its attachments.  In Py3k, all type
structs have to have all fields -- no binary backwards compatibility.
Had to change the complex object to a new-style number!

Thomas Wouters 4d70c3d9dd Partially merge trunk into p3yk. The removal of Mac/Tools is confusing svn
merge in bad ways, so I'll have to merge that extra-carefully (probably manually.)

  Quality control, meet exceptions.c.

  Fix a number of problems with the need for speed code:

  One is doing this sort of thing:

      Py_DECREF(self->field);
      self->field = newval;
      Py_INCREF(self->field);

  without being very sure that self->field doesn't start with a
  value that has a __del__, because that almost certainly can lead
  to segfaults.

  As self->args is constrained to be an exact tuple we may as well
  exploit this fact consistently.  This leads to quite a lot of
  simplification (and, hey, probably better performance).

  Add some error checking in places lacking it.

  Fix some rather strange indentation in the Unicode code.

  Delete some trailing whitespace.

  More to come, I haven't fixed all the reference leaks yet...

  Quality control, meet exceptions.c, round two.

  Make some functions that should have been static static.

  Fix a bunch of refleaks by fixing the definition of
  MiddlingExtendsException.

  Remove all the __new__ implementations apart from
  BaseException_new.  Rewrite most code that needs it to cope with
  NULL fields (such code could get excercised anyway, the
  __new__-removal just makes it more likely).  This involved
  editing the code for WindowsError, which I can't test.

  This fixes all the refleaks in at least the start of a regrtest
  -R :: run.

  ("Forward-port" of r46506)

  Remove various dependencies on dictionary order in the standard library
  tests, and one (clearly an oversight, potentially critical) in the
  standard library itself - base64.py.

  Remaining open issues:
   * test_extcall is an output test, messy to make robust
   * tarfile.py has a potential bug here, but I'm not familiar
     enough with this code.  Filed in as SF bug #1496501.
   * urllib2.HTTPPasswordMgr() returns a random result if there is more
     than one matching root path.  I'm asking python-dev for
     clarification...

  PyLong_FromString():  Continued fraction analysis (explained in
  a new comment) suggests there are almost certainly large input
  integers in all non-binary input bases for which one Python digit
  too few is initally allocated to hold the final result.  Instead
  of assert-failing when that happens, allocate more space.  Alas,
  I estimate it would take a few days to find a specific such case,
  so this isn't backed up by a new test (not to mention that such
  a case may take hours to run, since conversion time is quadratic
  in the number of digits, and preliminary attempts suggested that
  the smallest such inputs contain at least a million digits).

  [Bug #1473048]
  SimpleXMLRPCServer and DocXMLRPCServer don't look at
  the path of the HTTP request at all; you can POST or
  GET from / or /RPC2 or /blahblahblah with the same results.
  Security scanners that look for /cgi-bin/phf will therefore report
  lots of vulnerabilities.

  Fix: add a .rpc_paths attribute to the SimpleXMLRPCServer class,
  and report a 404 error if the path isn't on the allowed list.

  Possibly-controversial aspect of this change: the default makes only
  '/' and '/RPC2' legal.  Maybe this will break people's applications
  (though I doubt it).  We could just set the default to an empty tuple,
  which would exactly match the current behaviour.

  Armin committed his patch while I was reviewing it (I'm sure
  he didn't know this), so merged in some changes I made during
  review.  Nothing material apart from changing a new `mask` local
  from int to Py_ssize_t.  Mostly this is repairing comments that
  were made incorrect, and adding new comments.  Also a few
  minor code rewrites for clarity or helpful succinctness.

  Prevent an invalid memory read from test_coding in case the done flag is set.
  In that case, the loop isn't entered.  I wonder if rather than setting
  the done flag in the cases before the loop, if they should just exit early.

  This code looks like it should be refactored.

  pprint functions used to sort a dict (by key) if and only if
  the output required more than one line.  "Small" dicts got
  displayed in seemingly random order (the hash-induced order
  produced by dict.__repr__).  None of this was documented.
  Now pprint functions always sort dicts by key, and the docs
  promise it.

  SF bug #1473760 TempFile can hang on Windows.

  Python 2.4 changed ntpath.abspath to do an import
  inside the function.  As a result, due to Python's
  import lock, anything calling abspath on Windows
  (directly, or indirectly like tempfile.TemporaryFile)
  hung when it was called from a thread spawned as a
  side effect of importing a module.

  This is a depressingly frequent problem, and
  deserves a more general fix.  I'm settling for
  a micro-fix here because this specific one accounts
  for a report of Zope Corp's ZEO hanging on Windows,
  and it was an odd way to change abspath to begin
  with (ntpath needs a different implementation
  depending on whether we're actually running on
  Windows, and the _obvious_ way to arrange for that
  is not to bury a possibly-failing import _inside_
  the function).

  Note that if/when other micro-fixes of this kind
  get made, the new Lib/test/threaded_import_hangers.py
  is a convenient place to add tests for them.

  Add Gregory K. Johnson's revised version of mailbox.py (funded by
  the 2005 Summer of Code).

  The revision adds a number of new mailbox classes that support adding
  and removing messages; these classes also support mailbox locking and
  default to using email.Message instead of rfc822.Message.

  The old mailbox classes are largely left alone for backward compatibility.
  The exception is the Maildir class, which was present in the old module
  and now inherits from the new classes.  The Maildir class's interface
  is pretty simple, though, so I think it'll be compatible with existing
  code.

  (The change to the NEWS file also adds a missing word to a different
  news item, which unfortunately required rewrapping the line.)

  Move the PEP 343 documentation and implementation closer to the
  terminology in the alpha 1 documentation.

   - "context manager" reverts to its alpha 1 definition
   - the term "context specifier" goes away entirely
   - contextlib.GeneratorContextManager is renamed GeneratorContext

  There are still a number of changes relative to alpha 1:

    - the expression in the with statement is explicitly called the
      "context expression" in the language reference
    - the terms 'with statement context', 'context object' or 'with
      statement context' are used in several places instead of a bare
      'context'. The aim of this is to avoid ambiguity in relation to the
      runtime context set up when the block is executed, and the context
      objects that already exist in various application domains (such as
      decimal.Context)
    - contextlib.contextmanager is renamed to contextfactory
      This best reflects the nature of the function resulting from the
      use of that decorator
    - decimal.ContextManager is renamed to WithStatementContext
      Simple dropping the 'Manager' part wasn't possible due to the
      fact that decimal.Context already exists and means something
      different. WithStatementContext is ugly but workable.

  A technically unrelated change snuck into this commit:
  contextlib.closing now avoids the overhead of creating a
  generator, since it's trivial to implement that particular
  context manager directly.

  does not define MAXPATHLEN.) Cursory googling suggests Linux is following a

  The result of SF patch #1471578: big-memory tests for strings, lists and
  tuples. Lots to be added, still, but this will give big-memory people
  something to play with in 2.5 alpha 2, and hopefully get more people to
  write these tests.

  [Bug #1477102] Add necessary import to example

  This may be a useful style question for the docs -- should examples show
  the necessary imports, or should it be assumed that the reader will
  figure it out?  In the What's New, I'm not consistent but usually opt
  for omitting the imports.

   - Add new Warning class, ImportWarning

   - Warn-raise ImportWarning when importing would have picked up a directory
     as package, if only it'd had an __init__.py. This swaps two tests (for
     case-ness and __init__-ness), but case-test is not really more expensive,
     and it's not in a speed-critical section.

   - Test for the new warning by importing a common non-package directory on
     sys.path: site-packages

   - In regrtest.py, silence warnings generated by the build-environment
     because Modules/ (which is added to sys.path for Setup-created modules)
     has 'zlib' and '_ctypes' directories without __init__.py's.

  Bug #1334662 / patch #1335972:  int(string, base) wrong answers.

  In rare cases of strings specifying true values near sys.maxint,
  and oddball bases (not decimal or a power of 2), int(string, base)
  could deliver insane answers.  This repairs all such problems, and
  also speeds string->int significantly.  On my box, here are %
  speedups for decimal strings of various lengths:

  length speedup
  ------ -------
   1       12.4%
   2       15.7%
   3       20.6%
   4       28.1%
   5       33.2%
   6       37.5%
   7       41.9%
   8       46.3%
   9       51.2%
  10       19.5%
  11       19.9%
  12       23.9%
  13       23.7%
  14       23.3%
  15       24.9%
  16       25.3%
  17       28.3%
  18       27.9%
  19       35.7%

  Note that the difference between 9 and 10 is the difference between
  short and long Python ints on a 32-bit box.  The patch doesn't
  actually do anything to speed conversion to long:  the speedup is
  due to detecting "unsigned long" overflow more quickly.

  This is a bugfix candidate, but it's a non-trivial patch and it
  would be painful to separate the "bug fix" from the "speed up" parts.

  Heavily fiddled variant of patch #1442927: PyLong_FromString optimization.

  ``long(str, base)`` is now up to 6x faster for non-power-of-2 bases.  The
  largest speedup is for inputs with about 1000 decimal digits.  Conversion
  from non-power-of-2 bases remains quadratic-time in the number of input
  digits (it was and remains linear-time for bases 2, 4, 8, 16 and 32).

  Speedups at various lengths for decimal inputs, comparing 2.4.3 with
  current trunk.  Note that it's actually a bit slower for 1-digit strings:

  Fixed problem identified by Georg.  The special-case in-place code for replace
  made a copy of the string using PyString_FromStringAndSize(s, n) and modify
  the copied string in-place.  However, 1 (and 0) character strings are shared
  from a cache.  This cause "A".replace("A", "a") to change the cached version
  of "A" -- used by everyone.

  Now may the copy with NULL as the string and do the memcpy manually.  I've
  added regression tests to check if this happens in the future.  Perhaps
  there should be a PyString_Copy for this case?

  Changes to string.split/rsplit on whitespace to preallocate space in the
  results list.

  Originally it allocated 0 items and used the list growth during append.  Now
  it preallocates 12 items so the first few appends don't need list reallocs.

  ("Here are some words ."*2).split(None, 1) is 7% faster
  ("Here are some words ."*2).split() is is 15% faster

    (Your milage may vary, see dealership for details.)

  File parsing like this

      for line in f:
          count += len(line.split())

  is also about 15% faster.  There is a slowdown of about 3% for large
  strings because of the additional overhead of checking if the append is
  to a preallocated region of the list or not.  This will be the rare case.
  It could be improved with special case code but we decided it was not
  useful enough.

  There is a cost of 12*sizeof(PyObject *) bytes per list.  For the normal
  case of file parsing this is not a problem because of the lists have
  a short lifetime.  We have not come up with cases where this is a problem
  in real life.

  I chose 12 because human text averages about 11 words per line in books,
  one of my data sets averages 6.2 words with a final peak at 11 words per
  line, and I work with a tab delimited data set with 8 tabs per line (or
  9 words per line).  12 encompasses all of these.

  Also changed the last rstrip code to append then reverse, rather than
  doing insert(0).  The strip() and rstrip() times are now comparable.

  Patch 1145039.

  set_exc_info(), reset_exc_info():  By exploiting the
  likely (who knows?) invariant that when an exception's
  `type` is NULL, its `value` and `traceback` are also NULL,
  save some cycles in heavily-executed code.

  This is a "a kronar saved is a kronar earned" patch:  the
  speedup isn't reliably measurable, but it obviously does
  reduce the operation count in the normal (no exception
  raised) path through PyEval_EvalFrameEx().

  The tim-exc_sanity branch tries to push this harder, but
  is still blowing up (at least in part due to pre-existing
  subtle bugs that appear to have no other visible
  consequences!).

  Not a bugfix candidate.

Thomas Wouters 49fd7fa443 Merge p3yk branch with the trunk up to revision 45595. This breaks a fair
number of tests, all because of the codecs/_multibytecodecs issue described
here (it's not a Py3K issue, just something Py3K discovers):
http://mail.python.org/pipermail/python-dev/2006-April/064051.html

Hye-Shik Chang promised to look for a fix, so no need to fix it here. The
tests that are expected to break are:

test_codecencodings_cn
test_codecencodings_hk
test_codecencodings_jp
test_codecencodings_kr
test_codecencodings_tw
test_codecs
test_multibytecodec

This merge fixes an actual test failure (test_weakref) in this branch,
though, so I believe merging is the right thing to do anyway.

Brett Cannon bf36409e2a PEP 352 implementation. Creates a new base class, BaseException, which has an
added message attribute compared to the previous version of Exception.  It is
also a new-style class, making all exceptions now new-style.  KeyboardInterrupt
and SystemExit inherit from BaseException directly.  String exceptions now
raise DeprecationWarning.

Applies patch 1104669, and closes bugs 1012952 and 518846.
2006-03-01 04:25:17 +00:00
Guido van Rossum 1a5e21e033 Updates to the with-statement:
- New semantics for __exit__() -- it must re-raise the exception
  if type is not None; the with-statement itself doesn't do this.
  (See the updated PEP for motivation.)

- Added context managers to:
  - file
  - thread.LockType
  - threading.{Lock,RLock,Condition,Semaphore,BoundedSemaphore}
  - decimal.Context

- Added contextlib.py, which defines @contextmanager, nested(), closing().

- Unit tests all around; bot no docs yet.
2006-02-28 21:57:43 +00:00
Thomas Wouters f7f438ba3b SF patch #1438387, PEP 328: relative and absolute imports.
- IMPORT_NAME takes an extra argument from the stack: the relativeness of
   the import. Only passed to __import__ when it's not -1.

 - __import__() takes an optional 5th argument for the same thing; it
   __defaults to -1 (old semantics: try relative, then absolute)

 - 'from . import name' imports name (be it module or regular attribute)
   from the current module's *package*. Likewise, 'from .module import name'
   will import name from a sibling to the current module.

 - Importing from outside a package is not allowed; 'from . import sys' in a

Guido van Rossum c2e20744b2 PEP 343 -- the with-statement.
This was started by Mike Bland and completed by Guido

Thomas is working on Michael's patch for that aspect.

There's a small amount of code cleanup and refactoring
in ast.c, compile.c and ceval.c (I fixed the lltrace
behavior when EXT_POP is used -- however I had to make
lltrace a static global).

Jeremy Hylton af68c874a6 Add const to several API functions that take char *.
In C++, it's an error to pass a string literal to a char* function
without a const_cast().  Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.

I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc.  Predictably, there were a large set of functions that
needed to be fixed as a result of these changes.  The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].

One cast was required as a result of the changes:  A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.

* Applied NOP to previous transformations where appropriate.

Note, the NOP would not be necessary if other functions were
added to re-target jump addresses and update the co_lnotab mapping.
That would yield slightly faster and cleaner bytecode at the
expense of optimizer simplicity and of keeping it decoupled
from the line-numbering structure.

Jeremy Hylton 985eba53f5 Small function call optimization and special build option for call stats.
-DCALL_PROFILE: Count the number of function calls executed.

When this symbol is defined, the ceval mainloop and helper functions
count the number of function calls made.  It keeps detailed statistics
about what kind of object was called and whether the call hit any of
the special fast paths in the code.

Optimization:

When we take the fast_function() path, which seems to be taken for
most function calls, and there is minimal frame setup to do, avoid
call PyEval_EvalCodeEx().  The eval code ex function does a lot of
work to handle keywords args and star args, free variables,
generators, etc.  The inlined version simply allocates the frame and
copies the arguments values into the frame.

The optimization gets a little help from compile.c which adds a
CO_NOFREE flag to code objects that don't have free variables or cell
variables.  This change allows fast_function() to get into the fast
path with fewer tests.

I measure a couple of percent speedup in pystone with this change, but
there's surely more that can be done.

compile.c always generates DUP_TOP instead.

* Since only two cases remain for DUP_TOPX, replace
the switch-case with if-elseif.

* The in-lined integer compare does a CheckExact on
both arguments. Since the second is a little more
likely to fail, test it first.

* The switch-case for IS/IS_NOT and IN/NOT_IN can
separate the regular and inverted cases with no
additional work. For all four paths, saves a test and
jump.

Raymond Hettinger 8bb90a59a6 Replaced POP() with STACKADJ(-1) on lines where the result wasn't used.
The two are semantically equivalent, but the first triggered a compiler
warning about an unused variable.  Note, the preceding steps had already
accessed and decreffed the variable so the reference counts were fine.
2003-01-14 12:43:10 +00:00
Raymond Hettinger 71731d7f70 As discussed on python-dev, removed from DUP_TOPX support for the
parameter being either four or five.  Currently, compile.c does not
generate calls with a parameter higher than three.

May have to be reverted if the second alpha or beta shakes out some
other tool generating this op code with a parameter of four or five.

Raymond Hettinger 663004bb3d SF patch #664320: Replace push/pop clusters in ceval.c
Replaced groups of pushes and pops with indexed access to the stack and
a single adjustment (if needed) to the stacklevel.

Avoids scores of unnecessary increments and decrements to the stackpointer.
Removes unnecessary sequential dependencies so that the compiler has more
freedom for optimizations.  Frees the processor for more parallel and
pipelined execution by using mostly read-only access and having few pointer
adjustments just prior to a read or write.

Michael W. Hudson ca803a0dd7 One last tweak to the tracing machinery: this actually computes what I intended

Skip Montanaro 99dba27e9a Bump default check interval to 100 instructions. Computers are much faster

Skip Montanaro d581d7792b replace thread state objects' ticker and checkinterval fields with two

Guido van Rossum d8dbf847b6 Add a warning comment to the LOAD_GLOBAL inline code. 2002-08-19 21:17:53 +00:00
Guido van Rossum 3a4dfc87e6 Another ugly inlining hack, expanding the two PyDict_GetItem() calls
in LOAD_GLOBAL.  Besides saving a C function call, it saves checks
whether f_globals and f_builtins are dicts, and extracting and testing
the string object's hash code is done only once.  We bail out of the
inlining if the name is not exactly a string, or when its hash is -1;
because of interning, neither should ever happen.  I believe interning
guarantees that the hash code is set, and I believe that the 'names'
tuple of a code object always contains interned strings, but I'm not
assuming that -- I'm simply testing hash != -1.

On my home machine, this makes a pystone variant with new-style
classes and slots run at the same speed as classic pystone!  (With
new-style classes but without slots, it is still a lot slower.)

METH_VARARGS.

it might make a difference.

Jeremy Hylton e8c0432403 Move body of CALL_FUNCTION opcode into helper function.
This makes the code much easier to ready, because it is at a sane

nothing, except that I'm not going to worry about the performance
effects of the change.

Guido van Rossum c13f724af0 Streamline the fast track for CFunction calls a bit more: there was
nothing special done if keyword arguments were present, so test for

This ought to slow down CFunction calls with keyword args, but I don't
care; it's a tiny (1%) improvement for pystone.

Jeremy Hylton 938ace69a0 staticforward bites the dust.
The staticforward define was needed to support certain broken C
compilers (notably SCO ODT 3.0, perhaps early AIX as well) botched the
static keyword when it was used with a forward declaration of a static
initialized structure.  Standard C allows the forward declaration with
static, and we've decided to stop catering to broken C compilers.  (In
fact, we expect that the compilers are all fixed eight years later.)

I'm leaving staticforward and statichere defined in object.h as
static.  This is only for backwards compatibility with C extensions
that might still use it.

XXX I haven't updated the documentation.

This was a simple typo.  Strange that the compiler didn't catch it!
Instead of WHY_CONTINUE, two tests used CONTINUE_LOOP, which isn't a
why_code at all, but an opcode; but even though 'why' is declared as
an enum, comparing it to an int is apparently not even worth a
warning -- not in gcc, and not in VC++. :-(

Guido van Rossum cfbf1a33c1 Fix an issue that was reported in but unrelated to the main problem of
SF bug 535905 (Evil Trashcan and GC interaction).

The SETLOCAL() macro should not DECREF the local variable in-place and
then store the new value; it should copy the old value to a temporary
value, then store the new value, and then DECREF the temporary value.
This is because it is possible that during the DECREF the frame is
accessed by other code (e.g. a __del__ method or gc.collect()) and the
variable would be pointing to already-freed memory.

BUGFIX CANDIDATE!
2002-03-28 20:17:52 +00:00
Tim Peters 8e5fd53be0 SF bug 480215: softspace confused in nested print
This fixes the symptom, but PRINT_ITEM has no way to know what (if
anything) PyFile_WriteObject() writes unless the object being printed
is a string.  When the object isn't a string, this fix retains the
guess that softspace should be set after PyFile_WriteObject().
We might want to say that it's the job of filelike-object write methods
to leave the file's softspace in the correct state.  That would probably
be better -- but everyone relies on PRINT_ITEM to guess for them now.

Tim Peters 3caca2326e SF bug #488514: -Qnew needs work
Big Hammer to implement -Qnew as PEP 238 says it should work (a global
option affecting all instances of "/").

pydebug.h, main.c, pythonrun.c:  define a private _Py_QnewFlag flag, true
iff -Qnew is passed on the command line.  This should go away (as the
comments say) when true division becomes The Rule.  This is
deliberately not exposed to runtime inspection or modification:  it's
a one-way one-shot switch to pretend you're using Python 3.

ceval.c:  when _Py_QnewFlag is set, treat BINARY_DIVIDE as
BINARY_TRUE_DIVIDE.

test_{descr, generators, zipfile}.py:  fiddle so these pass under
-Qnew too.  This was just a matter of s!/!//! in test_generators and
test_zipfile.  test_descr was trickier, as testbinop() is passed
assumptions that "/" is the same as calling a "__div__" method; put
a temporary hack there to call "__truediv__" instead when the method
name is "__div__" and 1/2 evaluates to 0.5.

Three standard tests still fail under -Qnew (on Windows; somebody
please try the Linux tests with -Qnew too!  Linux runs a whole bunch
of tests Windows doesn't):
    test_augassign
    test_class
    test_coercion
I can't stay awake longer to stare at this (be my guest).  Offhand
cures weren't obvious, nor was it even obvious that cures are possible
without major hackery.

Question:  when -Qnew is in effect, should calls to __div__ magically
change into calls to __truediv__?  See "major hackery" at tail end of
last paragraph <wink>.

Tim Peters b13680bf03 SF bug #483469: crash on unbounded recursion in __del__.
PyEval_EvalCodeEx():  increment tstate->recursion_depth around the
decref of the frame, because the C stack for this call is still in
use and the decref can lead to __del__ methods getting called.

While this gives tstate->recursion_depth a value proportional to the
depth of the C stack (instead of a small constant no matter how
deeply __del__s recurse), it's not enough to stop the reported crash
when using the default recursion limit on Windows.

Fred Drake 4ec5d5699d Fix bug in profiler modifications detected only in debug builds.
The new profiler event stream includes a "return" event even when an
exception is being propogated, but the machinery that called the profile
hook did not save & restore the exception.  In debug mode, the exception
was detected during the execution of the profile callback, which did not
have the proper internal flags set for the exception.  Saving & restoring
the exception state solves the problem.
2001-10-04 19:26:43 +00:00
Fred Drake 8f51f54319 Rationalize the events passed to the profiler (no changes for the tracer).
The profiler does not need to know anything about the exception state,
so we no longer call it when an exception is raised.  We do, however,
make sure we *always* call the profiler when we exit a frame.  This
ensures that timing events are more easily isolated by a profiler and
finally clauses that do a lot of work don't have their time
mis-allocated.

When an exception is propogated out of the frame, the C callback for
the profiler now receives a PyTrace_RETURN event with an arg of NULL;
the Python-level profile hook function will see a 'return' event with
an arg of None.  This means that from Python it is impossible for the
profiler to determine if the frame exited with an exception or if it
returned None, but this doesn't matter for profiling.  A C-based
profiler could tell the difference, but this doesn't seem important.

ceval.c:eval_frame():  Simplify the code in two places so that the
                       profiler is called for every exit from a frame
                       and not for exceptions.

sysmodule.c:profile_trampoline():  Make sure we don't expose Python
                                   code to NULL; use None instead.

Jeremy Hylton c631489289 Prevent a NULL pointer from being pushed onto the stack.
It's possible for PyErr_NormalizeException() to set the traceback
pointer to NULL.  I'm not sure how to provoke this directly from
Python, although it may be possible.  The error occurs when an
exception is set using PyErr_SetObject() and another exception occurs
while PyErr_NormalizeException() is creating the exception instance.

XXX As a result of this change, it's possible for an exception to
occur but sys.last_traceback to be left undefined.  Not sure if this
is a problem.

Guido van Rossum 6f7993765a Add optional docstrings to member descriptors. For backwards
compatibility, this required all places where an array of "struct
memberlist" structures was declared that is referenced from a type's
tp_members slot to change the type of the structure to PyMemberDef;
"struct memberlist" is now only used by old code that still calls
PyMember_Get/Set.  The code in PyObject_GenericGetAttr/SetAttr now
calls the new APIs PyMember_GetOne/SetOne, which take a PyMemberDef
argument.

As examples, I added actual docstrings to the attributes of a few
types: file, complex, instance method, super, and xxsubtype.spamlist.

Also converted the symtable to new style getattr.

Guido van Rossum 7851eea5f2 build_class(): one more (hopefully the last) step on the way to
backwards compatibility.  When using the class of the first base as
the metaclass, use its __class__ attribute in preference over its
ob_type slot.  This ensures that we can still use classic classes as
metaclasse, as shown in the original "Metaclasses" essay.  This also
makes all the examples in Demo/metaclasses/ work again (maybe these
should be turned into a test suite?).

Neil Schemenauer 6c0f20088f Move call_trace(..., PyTrace_CALL, ...) call to top of eval_frame. That

Guido van Rossum 50d756e262 Fix SF bug #443600:
Change to get/set/del slice operations so that if the object doesn't
support slicing, *or* if either of the slice arguments is not an int
or long, we construct a slice object and call the get/set/del item
operation instead.  This makes it possible to design classes that
support slice arguments of non-integral types.

Tim Peters e2c18e90da ceval, PyEval_MergeCompilerFlags: wasn't merging in the
CO_FUTURE_DIVISION flag.  Redid this to use Jeremy's PyCF_MASK #define
instead, so we dont have to remember to fiddle individual feature names
here again.

pythonrun.h:  Also #define a PyCF_MASK_OBSOLETE mask.  This isn't used
yet, but will be as part of the PEP 264 implementation (compile() mustn't
raise an error just because old code uses a flag name that's become
obsolete; a warning may be appropriate, but not an error; so compile() has
to know about obsolete flags too, but nobody is going to remember to
update compile() with individual obsolete flag names across releases either
-- i.e., this is the flip side of PyEval_MergeCompilerFlags's oversight).
2001-08-17 20:47:47 +00:00
Martin v. Löwis e3eb1f2b23 Patch #427190: Implement and use METH_NOARGS and METH_O. 2001-08-16 13:15:00 +00:00
Jeremy Hylton 910d7d46dc Remove much dead code from ceval.c
The descr changes moved the dispatch for calling objects from
call_object() in ceval.c to PyObject_Call() in abstract.c.
call_object() and the many functions it used in ceval.c were no longer
used, but were not removed.

Rename meth_call() as PyCFunction_Call() so that it can be called by
the CALL_FUNCTION opcode in ceval.c.

Also, fix error message that referred to PyEval_EvalCodeEx() by its
old name eval_code2().  (I'll probably refer to it by its old name,
too.)
2001-08-12 21:52:24 +00:00
Jeremy Hylton b857ba261f Refactor future feature handling
Replace uses of PyCF_xxx with CO_xxx.

Replace individual feature slots in PyFutureFeatures with single
bitmask ff_features.

When flags must be transfered among the three parts of the interpreter
that care about them -- the pythonrun layer, the compiler, and the
future feature parser -- can simply or (|) the definitions.
2001-08-10 21:41:33 +00:00
Guido van Rossum 4668b000a1 Implement PEP 238 in its (almost) full glory.
This introduces:

- A new operator // that means floor division (the kind of division
  where 1/2 is 0).

- The "future division" statement ("from __future__ import division)
  which changes the meaning of the / operator to implement "true
  division" (where 1/2 is 0.5).

- New overloadable operators __truediv__ and __floordiv__.

- New slots in the PyNumberMethods struct for true and floor division,
  new abstract APIs for them, new opcodes, and so on.

I emphasize that without the future division statement, the semantics
of / will remain unchanged until Python 3.0.

Not yet implemented are warnings (default off) when / is used with int
or long arguments.

This has been on display since 7/31 as SF patch #443474.

Flames to /dev/null.

Tim Peters 6d6c1a35e0 Merge of descr-branch back into trunk. 2001-08-02 04:15:00 +00:00
Tim Peters 5ba5866281 Part way to allowing "from __future__ import generators" to communicate
that info to code dynamically compiled *by* code compiled with generators
enabled.  Doesn't yet work because there's still no way to tell the parser
that "yield" is OK (unlike nested_scopes, the parser has its fingers in
this too).
Replaced PyEval_GetNestedScopes by a more-general
PyEval_MergeCompilerFlags.  Perhaps I should not have?  I doubted it was
*intended* to be part of the public API, so just did.

Neil Schemenauer f8c7c20ba5 GC for generator objects. 2001-07-12 13:27:49 +00:00
Fred Drake 9e3ad78444 This change adjusts the profiling/tracing support so that the common
path (with no profile/trace function) through eval_code2() and
eval_frame() avoids several checks.

In the common cases of calls, returns, and exception propogation,
eval_code2() and eval_frame() used to test two values in the
thread-state: the profiling function and the tracing function.  With
this change, a flag is set in the thread-state if either of these is
active, allowing a single check to suffice when both are NULL.  This
also simplifies the code needed when either function is in use but is
already active (to avoid profiling/tracing the profiler/tracer); the
flag is set to 0 when the profile/trace code is entered, allowing the
same check to suffice for "already in the tracer" for call/return/
exception events.
2001-07-03 23:39:52 +00:00
Fred Drake 5755ce693d Revise the interface to the profiling and tracing support for the
Python interpreter.

This change adds two new C-level APIs:  PyEval_SetProfile() and
PyEval_SetTrace().  These can be used to install profile and trace
functions implemented in C, which can operate at much higher speeds
than Python-based functions.  The overhead for calling a C-based
profile function is a very small fraction of a percent of the overhead
involved in calling a Python-based function.

The machinery required to call a Python-based profile or trace
function been moved to sysmodule.c, where sys.setprofile() and
sys.setprofile() simply become users of the new interface.

As a side effect, SF bug #436058 is fixed; there is no longer a
_PyTrace_Init() function to declare.

2001-06-26 22:24:51 +00:00
Tim Peters d8e1c9e177 Add "gi_" (generator-iterator) prefix to names of genobject members.

2001-06-26 20:58:58 +00:00
Tim Peters ad1a18b78e Change the semantics of "return" in generators, as discussed on the
Iterators list and Python-Dev; e.g., these all pass now:

def g1():
    try:
        return
    except:
        yield 1
assert list(g1()) == []

def g2():
    try:
        return
    finally:
        yield 1
assert list(g2()) == [1]

def g3():
    for i in range(3):
        yield None
    yield None
assert list(g3()) == [None] * 4

compile.c:  compile_funcdef and com_return_stmt:  Just van Rossum's patch
to compile the same code for "return" regardless of function type (this
goes back to the previous scheme of returning Py_None).

ceval.c:  gen_iternext:  take a return (but not a yield) of Py_None as
meaning the generator is exhausted.
2001-06-23 06:19:16 +00:00
Tim Peters 5eb4b87ae6 gen_iternext(): Don't assume that the current thread state's frame is
not NULL.  I don't think it can be NULL from Python code, but if using
generators via the C API I expect a NULL frame is possible.
2001-06-23 05:47:56 +00:00
Tim Peters 8c96369513 PyFrameObject: rename f_stackbottom to f_stacktop, since it points to
the next free valuestack slot, not to the base (in America, stacks push
and pop at the top -- they mutate at the bottom in Australia <winK>).
eval_frame():  assert that f_stacktop isn't NULL upon entry.
frame_delloc():  avoid ordered pointer comparisons involving f_stacktop
when f_stacktop is NULL.

Neil Schemenauer 2b13ce8317 Try to avoid creating reference cycles involving generators. Only keep a
reference to f_back when its really needed.  Do a little whitespace
normalization as well.  This whole file is a big war between tabs and spaces

2001-06-21 02:41:10 +00:00
Tim Peters 6302ec63fc gen_iternext(): repair subtle refcount problem.
NeilS, please check!  This came from staring at your genbug.py, but I'm
not sure it plugs all possible holes.  Without this, I caught a
frameobject refcount going negative, and it was also the cause (in debug
build) of _Py_ForgetReference's attempt to forget an object with already-
NULL _ob_prev and _ob_next pointers -- although I'm still not entirely
sure how!  Part of the difficulty is that frameobjects are stored on a
free list that gets recycled very quickly, so if there's a stray pointer
to one of them it never looks like an insane frameobject (never goes
trough the free() mangling MS debug forces, etc).

2001-06-18 22:08:13 +00:00
Fred Drake d083839fb4 Instead of initializing & interning the strings passed to the profile
and trace functions lazily, which incurs extra argument pushing and checks
in the C overhead for profiling/tracing, create the strings semi-lazily
when the Python code first registers a profile or trace function.  This
simplifies the trampoline into the profile/trace functions.

Tim Peters 239508cd10 SF bug 433228: repr(list) woes when len(list) big
call_object:  If the object isn't callable, display its type in the error
msg rather than its repr.
Bugfix candidate.
2001-06-16 00:09:28 +00:00
Fred Drake 904aa7bb00 call_trace(): Add an additional parameter -- pointer to a PyObject*
that should be used to cache an interned version of the event
    string passed to the profile/trace function.  call_trace() will
    create interned strings and cache them in using the storage
    specified by this additional parameter, avoiding a lot of string
    object creation at runtime when using the profiling or tracing
    functions.

All call sites are modified to pass the additional parameter, and four
static PyObject* variables are allocated to cache the interned string
objects.

This closes SF patch #431257.
2001-06-08 04:33:09 +00:00
Jeremy Hylton 4c9dace392 Fix bug reported by Tim Peters on python-dev:

2001-05-29 16:23:26 +00:00
Jeremy Hylton da20fce9c3 Add a second special case to the inline function call code in eval_code2().
If we have a PyCFunction (builtin) and it is METH_VARARGS only, load
the args and dispatch to call_cfunction() directly.  This provides a
small speedup for perhaps the most common function calls -- builtins.
2001-05-18 20:53:14 +00:00

Jeremy Hylton 960d948e7c improved error message-- names the type of the unexpected object 2001-04-27 02:25:33 +00:00
Guido van Rossum 213c7a6aa5 Mondo changes to the iterator stuff, without changing how Python code
sees it (test_iter.py is unchanged).

- Added a tp_iternext slot, which calls the iterator's next() method;
  this is much faster for built-in iterators over built-in types
  such as lists and dicts, speeding up pybench's ForLoop with about
  25% compared to Python 2.1.  (Now there's a good argument for
  iterators. ;-)

- Renamed the built-in sequence iterator SeqIter, affecting the C API
  functions for it.  (This frees up the PyIter prefix for generic
  iterator operations.)

- Added PyIter_Check(obj), which checks that obj's type has a
  tp_iternext slot and that the proper feature flag is set.

- Added PyIter_Next(obj) which calls the tp_iternext slot.  It has a
  somewhat complex return condition due to the need for speed: when it
  returns NULL, it may not have set an exception condition, meaning
  the iterator is exhausted; when the exception StopIteration is set
  (or a derived exception class), it means the same thing; any other
  exception means some other error occurred.

Tim Peters cf96de052f SF but #417587: compiler warnings compiling 2.1.
Repaired *some* of the SGI compiler warnings Sjoerd Mullender reported.
2001-04-21 02:46:11 +00:00
Guido van Rossum 59d1d2b434 Iterators phase 1. This comprises:
new slot tp_iter in type object, plus new flag Py_TPFLAGS_HAVE_ITER
new C API PyObject_GetIter(), calls tp_iter
new builtin iter(), with two forms: iter(obj), and iter(function, sentinel)
new internal object types iterobject and calliterobject
new exception StopIteration
new opcodes for "for" loops, GET_ITER and FOR_ITER (also supported by dis.py)
new magic number for .pyc files
new special method for instances: __iter__() returns an iterator
iteration over dictionaries: "for x in dict" iterates over the keys
iteration over files: "for x in file" iterates over lines

TODO:

documentation
test suite
decide whether to use a different way to spell iter(function, sentinal)
decide whether "for key in dict" is a good idea
use iterators in map/filter/reduce, min/max, and elsewhere (in/not in?)
speed tuning (make next() a slot tp_next???)
2001-04-20 19:13:02 +00:00
Jeremy Hylton c76770c68c Change error message raised when free variable is not yet bound. It
now raises NameError instead of UnboundLocalError, because the var in
question is definitely not local.  (This affects test_scope.py)

Also update the recent fix by Ping using get_func_name().  Replace
tests of get_func_name() return value with call to get_func_desc() to
match all the other uses.
2001-04-13 16:51:46 +00:00
Guido van Rossum d9994e0115 Patch by Ping (SF bug 415879, Exception.__init__() causes segfault):
Calling an unbound method on a C extension class without providing
   an instance can yield a segfault.  Try "Exception.__init__()" or
   "ValueError.__init__()".

   This is a simple fix. The error-reporting bits in call_method
   mistakenly treat the misleadingly-named variable "func" as a
   function, when in fact it is a method.

   If we let get_func_name take care of the work, all is fine.
2001-04-13 15:42:40 +00:00
Jeremy Hylton 512a237725 Fix exception handling for non-PyFunction objects, SF bug 414743.
Fix based on patch #414750 by Michael Hudson.

New functions get_func_name() and get_func_desc() return reasonable
names and descriptions for all objects.  XXX Even objects that aren't
actually callable.
2001-04-11 13:52:29 +00:00
Jeremy Hylton bc32024769 Extend support for from __future__ import nested_scopes
If a module has a future statement enabling nested scopes, they are
also enable for the exec statement and the functions compile() and
execfile() if they occur in the module.

If Python is run with the -i option, which enters interactive mode
after executing a script, and the script it runs enables nested
scopes, they are also enabled in interactive mode.

XXX The use of -i with -c "from __future__ import nested_scopes" is
not supported.  What's the point?

To support these changes, many function variants have been added to
pythonrun.c.  All the variants names end with Flags and they take an
extra PyCompilerFlags * argument.  It is possible that this complexity
will be eliminated in a future version of the interpreter in which
nested scopes are not optional.
2001-03-22 02:47:58 +00:00
Jeremy Hylton 061d106a0f If a code object is compiled with nested scopes, define the CO_NESTED flag.
Add PyEval_GetNestedScopes() which returns a non-zero value if the
code for the current interpreter frame has CO_NESTED defined.
2001-03-22 02:32:48 +00:00
Guido van Rossum 66b0e9c2a7 Use PyObject_IsInstance() to check whether the first argument to an
unbound method is of the right type.  Hopefully this solves SF patch
#409355 (Meta-class inheritance problem); I have no easy way to test.
2001-03-21 19:17:22 +00:00
Jeremy Hylton 220ae7c0bf Fix PyFrame_FastToLocals() and counterpart to deal with cells and
frees.  Note there doesn't seem to be any way to test LocalsToFast(),
because the instructions that trigger it are illegal in nested scopes
with free variables.

Fix allocation strategy for cells that are also formal parameters.
Instead of emitting LOAD_FAST / STORE_DEREF pairs for each parameter,
have the argument handling code in eval_code2() do the right thing.

A side-effect of this change is that cell variables that are also
arguments are listed at the front of co_cellvars in the order they
appear in the argument list.
2001-03-21 16:43:47 +00:00
Jeremy Hylton 30c9f3991c Variety of small INC/DECREF patches that fix reported memory leaks
with free variables.  Thanks to Martin v. Loewis for finding two of
the problems.  This fixes SF buf 405583.

There is also a C API change: PyFrame_New() is reverting to its
pre-2.1 signature.  The change introduced by nested scopes was a
mistake.  XXX Is this okay between beta releases?

cell_clear(), the GC helper, must decref its reference to break
cycles.

frame_dealloc() must dealloc all cell vars and free vars in addition
to locals.

eval_code2() setup code must INCREF cells it copies out of the
closure.

The STORE_DEREF opcode implementation must DECREF the object it passes
to PyCell_Set().

discussion on python-dev.  'from mod import *' is still banned except
at the module level.

Fix value for special NOOPT entry in symtable.  Initialze to 0 instead

Tim Peters 1ff31f9534 SF bug #130532: newest CVS won't build on AIX.

2001-01-31 01:16:47 +00:00
Jeremy Hylton 2b724da8d9 Remove f_closure slot of frameobject and use f_localsplus instead.
This change eliminates an extra malloc/free when a frame with free
variables is created.  Any cell vars or free vars are stored in
f_localsplus after the locals and before the stack.

eval_code2() fills in the appropriate values after handling
initialization of locals.

To track the size the frame has an f_size member that tracks the total
size of f_localsplus. It used to be implicitly f_nlocals + f_stacksize.
2001-01-29 22:51:52 +00:00
Jeremy Hylton 64949cb753 PEP 227 implementation
The majority of the changes are in the compiler.  The mainloop changes
primarily to implement the new opcodes and to pass a function's
closure to eval_code2().  Frames and functions got new slots to hold
the closure.

Include/compile.h
    Add co_freevars and co_cellvars slots to code objects.
    Update PyCode_New() to take freevars and cellvars as arguments
Include/funcobject.h
    Add func_closure slot to function objects.
    Add GetClosure()/SetClosure() functions (and corresponding
    macros) for getting at the closure.
Include/frameobject.h
    PyFrame_New() now takes a closure.
Include/opcode.h
    Add four new opcodes: MAKE_CLOSURE, LOAD_CLOSURE, LOAD_DEREF,
    STORE_DEREF.
    Remove comment about old requirement for opcodes to fit in 7
    bits.
compile.c
    Implement changes to code objects for co_freevars and co_cellvars.

    Modify symbol table to use st_cur_name (string object for the name
    of the current scope) and st_cur_children (list of nested blocks).
    Also define st_nested, which might more properly be called
    st_cur_nested.  Add several DEF_XXX flags to track def-use
    information for free variables.

    New or modified functions of note:
    com_make_closure(struct compiling *, PyCodeObject *)
        Emit LOAD_CLOSURE opcodes as needed to pass cells for free
        variables into nested scope.
    com_addop_varname(struct compiling *, int, char *)
        Emits opcodes for LOAD_DEREF and STORE_DEREF.
    get_ref_type(struct compiling *, char *name)
        Return NAME_CLOSURE if ref type is FREE or CELL
    symtable_load_symbols(struct compiling *)
        Decides what variables are cell or free based on def-use info.
        Can now raise SyntaxError if nested scopes are mixed with
        exec or from blah import *.
    make_scope_info(PyObject *, PyObject *, int, int)
        Helper functions for symtable scope stack.
    symtable_update_free_vars(struct symtable *)
        After a code block has been analyzed, it must check each of
        its children for free variables that are not defined in the
        block.  If a variable is free in a child and not defined in
        the parent, then it is defined by block the enclosing the
        current one or it is a global.  This does the right logic.
    symtable_add_use() is now a macro for symtable_add_def()
    symtable_assign(struct symtable *, node *)
        Use goto instead of for (;;)

    Fixed bug in symtable where name of keyword argument in function
    call was treated as assignment in the scope of the call site. Ex:
        def f():
            g(a=2) # a was considered a local of f

ceval.c
    eval_code2() now take one more argument, a closure.
    Implement LOAD_CLOSURE, LOAD_DEREF, STORE_DEREF, MAKE_CLOSURE>

    Also: When name error occurs for global variable, report that the
    name was global in the error mesage.

Objects/frameobject.c
    Initialize f_closure to be a tuple containing space for cellvars
    and freevars.  f_closure is NULL if neither are present.
Objects/funcobject.c
    Add support for func_closure.
Python/import.c
    Change the magic number.

Jeremy Hylton c862cf400f clearer error messages for apply() and "no locals" 2001-01-19 03:25:05 +00:00
Guido van Rossum ac7be6888b Rich comparisons fall-out:
- Use PyObject_RichCompare*() where possible: when comparing
  keyword arguments, in _PyEval_SliceIndex(), and of course in
  cmp_outcome().

Unrelated stuff:

- Removed all trailing whitespace.

- Folded some long lines.

Ka-Ping Yee 2057970601 This patch makes sure that the function name always appears in the error
message, and tries to make the messages more consistent and helpful when
the wrong number of arguments or duplicate keyword arguments are supplied.
Comes with more tests for test_extcall.py and and an update to an error
message in test/output/test_pyexpat.

Guido van Rossum 18d4d8f71d Two changes to from...import:
1) "from M import X" now works even if M is not a real module; it's
   basically a getattr() operation with AttributeError exceptions
   changed into ImportError.

2) "from M import *" now looks for M.__all__ to decide which names to
   import; if M.__all__ doesn't exist, it uses M.__dict__.keys() but
   filters out names starting with '_' as before.  Whether or not
   __all__ exists, there's no restriction on the type of M.

Charles G. Waldman eec72a7fd9 Add missing Py_DECREF in fast_cfunction. Partial fix for SF bug
#127699.

Fred Drake 1a7aab70d1 When a PyCFunction that takes only positional parameters is called with
an empty keywords dictionary (via apply() or the extended call syntax),
the keywords dict should be ignored.  If the keywords dict is not empty,
TypeError should be raised.  (Between the restructuring of the call
machinery and this patch, an empty dict in this situation would trigger
a SystemError via PyErr_BadInternalCall().)

Added regression tests to detect errors for this.

Jeremy Hylton 5282044be7 Revised implementation of CALL_FUNCTION and friends.
More revision still needed.

Much of the code that was in the mainloop was moved to a series of
helper functions.  PyEval_CallObjectWithKeywords was split into two
parts.  The first part now only does argument handling.  The second
part is now named call_object and delegates the call to a
call_(function,method,etc.) helper.

XXX The call_XXX helper functions should be replaced with tp_call
functions for the respective types.

The CALL_FUNCTION implementation contains three kinds of optimization:
1. fast_cfunction and fast_function are called when the arguments on
   the stack can be passed directly to eval_code2() without copying
   them into a tuple.
2. PyCFunction objects are dispatched immediately, because they are
   presumed to occur more often than anything else.
3. Bound methods are dispatched inline.  The method object contains a
   pointer to the function object that will be called.  The function
   is called from within the mainloop, which may allow optimization #1
   to be used, too.

The extened call implementation -- f(*args) and f(**kw) -- are
implemented as a separate case in the mainloop.  This allows the
common case of normal function calls to execute without wasting time
on checks for extended calls, although it does introduce a small
amount of code duplication.

Also, the unused final argument of eval_code2() was removed.  This is
probably the last trace of the access statement :-).

Jeremy Hylton 6b4ec5135b Fix for SF bug #117241
When a method is called with no regular arguments and * args, defer
the first arg is subclass check until after the * args have been
expanded.

N.B. The CALL_FUNCTION implementation is getting really hairy; should
review it to see if it can be simplified.

Changes to error messages to increase consistency & clarity.

This (mostly) closes SourceForge patch #101839.

Thomas Wouters 0be483fd4d Do a better job at staying on-screen :P (Sorry, it's late here.) I'm
assuming here that the ANSI-C adjacent-string-concatenation technique is
allowable, now that Python requires an ANSI C compiler.

Thomas Wouters 8fb62a2e9a Adjust debugging code in the implementation of the DUP_TOPX bytecode, use
Py_FatalError() instead, and clarify the message somewhat. As discussed on
python-dev.
2000-10-11 23:20:09 +00:00
Fred Drake 48fba733b9 Remove the last gcc -Wall warning about possible use of an uninitialized
variable.  w should be initialized before entering the bytecode
interpretation loop since we only need one initialization to satisfy the
compiler.
2000-10-11 13:54:07 +00:00
Tim Peters 35ba689cab Attempt to fix bogus gcc -Wall warnings reported by Marc-Andre Lemburg,
by making the DUP_TOPX code utterly straightforward.  This also gets rid
of all normal-case internal DUP_TOPX if/branches, and allows replacing one
POP() with TOP() in each case, so is a good idea regardless.

Fred Drake d5fadf75e4 Rationalize use of limits.h, moving the inclusion to Python.h.
Add definitions of INT_MAX and LONG_MAX to pyport.h.
Remove includes of limits.h and conditional definitions of INT_MAX
and LONG_MAX elsewhere.

This closes SourceForge patch #101659 and bug #115323.

Marc-André Lemburg d1ba443206 This patch adds a new Python C API called PyString_AsStringAndSize()
which implements the automatic conversion from Unicode to a string
object using the default encoding.

The new API is then put to use to have eval() and exec accept
Unicode objects as code parameter. This closes bugs #110924
and #113890.

As side-effect, the traditional C APIs PyString_Size() and
PyString_AsString() will also accept Unicode objects as
parameters.

out again after we complete switching to C++ <wink>.  Thanks to Greg Stein
for hitting me.

Guido van Rossum 349ff6f7e2 Set the recursion limit to 1000 -- 2500 was not enough, let's be
conservative.
