that their uses can be prettier. I've come to despise the names I picked
for these things, though, and expect to change all of them -- I changed
a bunch of other files to use them (replacing #ifdef blocks), but the
names were so obscure out of context that I backed that all out again.
The recent SSL changes resulted in important, but subtle changes to
close() semantics. Since builtin socket makefile() is not called for
SSL connections, we don't get separately closeable fds for connection
and response. Comments in the code explain how to restore makefile
semantics.
Bug fix candidate.
.splitlines() on them, since they may be Header instances.
test_multilingual(), test_header_ctor_default_args(): New tests of
make_header() and that Header can take all default arguments.
create a Header instance. Closes feature request #539481.
Header.__init__(): Allow the initial string to be omitted.
__eq__(), __ne__(): Support rich comparisons for equality of Header
instances withy Header instances or strings.
Also, update a bunch of docstrings.
more trivial lexical helper macros so that uses of these guys expand
to nothing at all when they're not enabled. This should help sub-
standard compilers that can't do a good job of optimizing away the
previous "(void)0" expressions.
Py_DECREF: There's only one definition of this now. Yay! That
was that last one in the family defined multiple times in an #ifdef
maze.
Py_FatalError(): Changed the char* signature to const char*.
_Py_NegativeRefcount(): New helper function for the Py_REF_DEBUG
expansion of Py_DECREF. Calling an external function cuts down on
the volume of generated code. The previous inline expansion of abort()
didn't work as intended on Windows (the program often kept going, and
the error msg scrolled off the screen unseen). _Py_NegativeRefcount
calls Py_FatalError instead, which captures our best knowledge of
how to abort effectively across platforms.
argument to the constructor -- defaulting to true -- which is
different than Anthony's approach of using global state.
parse(), parsestr(): Grow a `headersonly' argument which stops parsing
once the header block has been seen, i.e. it does /not/ parse or even
read the body of the message. This is used for parsing message/rfc822
type messages.
We need test cases for the non-strict parsing. Anthony will supply
these.
_parsebody(): We can get rid of the isdigest end-of-line kludges,
although we still need to know if we're parsing a multipart/digest so
we can set the default type accordingly.
text/plain but the RFCs state that inside a multipart/digest, the
default type is message/rfc822. To preserve idempotency, we need a
separate place to define the default type than the Content-Type:
header.
get_default_type(), set_default_type(): Accessor and mutator methods
for the default type.
recursive generation).
_dispatch(): If the message object doesn't have a Content-Type:
header, check its default type instead of assuming it's text/plain.
This makes for correct generation of message/rfc822 containers.
_handle_multipart(): We can get rid of the isdigest kludge. Just
print the message as normal and everything will work out correctly.
_handle_mulitpart_digest(): We don't need this anymore either.
ndiff function, so just alias it to assertEqual in that case.
Various: make sure all openfile()/read()'s are wrapped in
try/finally's so the file gets closed.
A bunch of new tests checking the corner cases for multipart/digest
and message/rfc822.
Repair segfaults and infinite loops in COUNT_ALLOCS builds in the
presence of new-style (heap-allocated) classes/types.
Bugfix candidate. I'll backport this to 2.2. It's irrelevant in 2.1.
this file; the lack of this was causing the A4 version of tutorial to
use really bad Type 3 fonts instead of Type 1 fonts, which also
bloated the file size substantially.
I thought there was a SourceForge bug for this, but couldn't find it.
children gets large, to avoid severe platform realloc() degeneration
in extreme cases (like test_longexp).
Bugfix candidate.
This was doing extremely timid over-allocation, just rounding up to the
nearest multiple of 3. Now so long as the number of children is <= 128,
it rounds up to a multiple of 4 but via a much faster method. When the
number of children exceeds 128, though, and more space is needed, it
doubles the capacity. This is aggressive over-allocation.
SF patch <http://www.python.org/sf/578297> has Andrew MacIntyre using
PyMalloc in the parser to overcome platform malloc problems in
test_longexp on OS/2 EMX. Jack Jansen notes there that it didn't help
him on the Mac, because the Mac has problems with frequent ever-growing
reallocs, not just with gazillions of teensy mallocs. Win98 has no
visible problems with test_longexp, but I tried boosting the test-case
size and soon got "senseless" MemoryErrors out of it, and soon after
crashed the OS: as I've seen in many other contexts before, while the
Win98 realloc remains zippy in bad cases, it leads to extreme
fragmentation of user address space, to the point that the OS barfs.
I don't yet know whether this fixes Jack's Mac problems, but it does cure
Win98's problems when boosting the test case size. It also speeds
test_longexp in its unaltered state.
that have taken me "too long" to reverse-engineer over the years.
Vastly reduced the nesting level and redundancy of #ifdef-ery.
Took a light stab at repairing comments that are no longer true.
sys_gettotalrefcount(): Changed to enable under Py_REF_DEBUG.
It was enabled under Py_TRACE_REFS, which was much heavier than
necessary. sys.gettotalrefcount() is now available in a
Py_REF_DEBUG-only build.
