* mysnprintf.c: Massive rewrite of PyOS_snprintf and PyOS_vsnprintf, toTim Peters2001-12-031-8/+1
| | | | | | | | | | | | | | | use wrappers on all platforms, to make this as consistent as possible x- platform (in particular, make sure there's at least one \0 byte in the output buffer). Also document more of the truth about what these do. getargs.c, seterror(): Three computations of remaining buffer size were backwards, thus telling PyOS_snprintf the buffer is larger than it actually is. This matters a lot now that PyOS_snprintf ensures there's a trailing \0 byte (because it didn't get the truth about the buffer size, it was storing \0 beyond the true end of the buffer). sysmodule.c, mywrite(): Simplify, now that PyOS_vsnprintf guarantees to produce a \0 byte.
* mywrite(): The test for trouble in PyOS_vsnprintf was wrong on bothTim Peters2001-12-021-3/+10

* Use PyOS_vsnprintf() and check its return value.Jeremy Hylton2001-11-281-2/+9
| | | | | | If it returns -1 (which indicates overflow on old Linux platforms and perhaps on Windows) or size greater than buffer, write a message indicating that the previous message was truncated.

* Rationalize the events passed to the profiler (no changes for the tracer).Fred Drake2001-10-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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.
* Patch #445762: Support --disable-unicodeMartin v. Löwis2001-08-171-0/+10
| | | | | | | | - Do not compile unicodeobject, unicodectype, and unicodedata if Unicode is disabled - check for Py_USING_UNICODE in all places that use Unicode functions - disables unicode literals, and the builtin functions - add the types.StringTypes list - remove Unicode literals from most tests.

* Patch #412229: Add functions sys.getdlopenflags and sys.setdlopenflags.Martin v. Löwis2001-07-181-0/+52
| | | | Add dlopenflags to PyInterpreterState, and use it in dlopen calls.
* Revise the interface to the profiling and tracing support for theFred Drake2001-06-271-13/+110
| | | | | | | | | | | | | | | | | | 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.
* Encode surrogates in UTF-8 even for a wide Py_UNICODE.Martin v. Löwis2001-06-271-0/+4
| | | | | | | Implement sys.maxunicode. Explicitly wrap around upper/lower computations for wide Py_UNICODE. When decoding large characters with UTF-8, represent expected test results using the \U notation.
* Instead of initializing & interning the strings passed to the profileFred Drake2001-06-161-0/+6
| | | | | | | 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.

* Add sys.excepthook.Ka-Ping Yee2001-03-231-11/+47
| | | | | | | | Update docstring and library reference section on 'sys' module. New API PyErr_Display, just for displaying errors, called by excepthook. Uncaught exceptions now call sys.excepthook; if that fails, we fall back to calling PyErr_Display directly. Also comes with sys.__excepthook__ and sys.__displayhook__.

* Create a new section of pyport.h to hold all external function declarationsThomas Wouters2000-07-241-1/+0
| | | | | | | | | | | | | | for systems that are missing those declarations from system include files. Start by moving a pointy-haired ones from their previous locations to the new section. (The gethostname() one, for instance, breaks on several systems, because some define it as (char *, size_t) and some as (char *, int).) I purposely decided not to include the summary of used #defines like Tim did in the first section of pyport.h. In my opinion, the number of #defines likedly to be used by this section would make such an overview unwieldy. I would suggest documenting the non-obvious ones, though.

* New APIs to write to sys.stdout or sys.stderr using a printf-like interface.Guido van Rossum1998-05-121-0/+90
| | | | | | | | | | | | | | | | | | | | | | | | Adapted from code submitted by Just van Rossum. PySys_WriteStdout(format, ...) PySys_WriteStderr(format, ...) The first function writes to sys.stdout; the second to sys.stderr. When there is a problem, they write to the real (C level) stdout or stderr; no exceptions are raised (but a pending exception may be cleared when a new exception is caught). Both take a printf-style format string as their first argument followed by a variable length argument list determined by the format string. *** WARNING *** The format should limit the total size of the formatted output string to 1000 bytes. In particular, this means that no unrestricted "%s" formats should occur; these should be limited using "%.<N>s where <N> is a decimal number calculated so that <N> plus the maximum size of other formatted text does not exceed 1000 bytes. Also watch out for "%f", which can print hundreds of digits for very large numbers.
