* Useful future statement support for the interactive interpreterJeremy Hylton2001-03-011-15/+25
| | | | | | | | | | | | | | | | | | | | | | | | (Also remove warning about module-level global decl, because we can't distinguish from code passed to exec.) Define PyCompilerFlags type contains a single element, cf_nested_scopes, that is true if a nested scopes future statement has been entered at the interactive prompt. New API functions: PyNode_CompileFlags() PyRun_InteractiveOneFlags() -- same as their non Flags counterparts except that the take an optional PyCompilerFlags pointer compile.c: In jcompile() use PyCompilerFlags argument. If cf_nested_scopes is true, compile code with nested scopes. If it is false, but the code has a valid future nested scopes statement, set it to true. pythonrun.c: Create a new PyCompilerFlags object in PyRun_InteractiveLoop() and thread it through to PyRun_InteractiveOneFlags().
* Now that Jeremy is asking about this code, it looks really bogus to me,Fred Drake2001-02-281-18/+0
| | | | | so let's rip it out. The constructor for SyntaxError does the right thing, so we do not need to do it again.
* Print the offending line of code in the traceback for SyntaxErrorsJeremy Hylton2001-02-281-36/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | raised by the compiler. XXX For now, text entered into the interactive intepreter is not printed in the traceback. Inspired by a patch from Roman Sulzhyk compile.c: Add helper fetch_program_text() that opens a file and reads until it finds the specified line number. The code is a near duplicate of similar code in traceback.c. Modify com_error() to pass two arguments to SyntaxError constructor, where the second argument contains the offending text when possible. Modify set_error_location(), now used only by the symtable pass, to set the text attribute on existing exceptions. pythonrun.c: Change parse_syntax_error() to continue of the offset attribute of a SyntaxError is None. In this case, it sets offset to -1. Move code from PyErr_PrintEx() into helper function print_error_text(). In the helper, only print the caret for a SyntaxError if offset > 0.
* Bug #132850 unix line terminator on windows.Tim Peters2001-02-171-10/+14
| | | | Miserable hack to replace the previous miserable hack in maybe_pyc_file.
* Ugly fix for SF bug 131239 (-x flag busted).Tim Peters2001-02-111-4/+15
| | | | | | Bug was introduced by tricks played to make .pyc files executable via cmdline arg. Then again, -x worked via a trick to begin with. If anyone can think of a portable way to test -x, be my guest!
* Move a bunch of definitions that were internal to compile.c toJeremy Hylton2001-02-021-0/+14
| | | | | | | | | | | | | | | | | | symtable.h, so that they can be used by external module. Improve error handling in symtable_enter_scope(), which return an error code that went unchecked by most callers. XXX The error handling in symtable code is sloppy in general. Modify symtable to record the line number that begins each scope. This can help to identify which code block is being referred to when multiple blocks are bound to the same name. Add st_scopes dict that is used to preserve scope info when PyNode_CompileSymtable() is called. Otherwise, this information is tossed as soon as it is no longer needed. Add Py_SymtableString() to pythonrun; analogous to Py_CompileString().
* It's unclear whether PyMarshal_XXX() are part of the public or private API.Tim Peters2001-01-281-1/+1
| | | | | | | | | | They're named as if public, so I did a Bad Thing by changing PyMarshal_ReadObjectFromFile() to suck up the remainder of the file in one gulp: anyone who counted on that leaving the file pointer merely at the end of the next object would be screwed. So restored PyMarshal_ReadObjectFromFile() to its earlier state, renamed the new greedy code to PyMarshal_ReadLastObjectFromFile(), and changed Python internals to call the latter instead.
* Bug #128475: mimetools.encode (sometimes) fails when called from a thread.Tim Peters2001-01-211-1/+10
| | | | | | | | pythonrun.c: In Py_Finalize, don't reset the initialized flag until after the exit funcs have run. atexit.py: in _run_exitfuncs, mutate the list of pending calls in a threadsafe way. This wasn't a contributor to bug 128475, it just burned my eyeballs when looking at that bug.

* Hard to believe Guido compiled this! Function lacked a return stmt.Tim Peters2000-08-271-1/+1

* Add three new APIs: PyRun_AnyFileEx(), PyRun_SimpleFileEx(),Guido van Rossum2000-08-271-7/+33
| | | | | | | | | | | | | | PyRun_FileEx(). These are the same as their non-Ex counterparts but have an extra argument, a flag telling them to close the file when done. Then this is used by Py_Main() and execfile() to close the file after it is parsed but before it is executed. Adding APIs seems strange given the feature freeze but it's the only way I see to close the bug report without incompatible changes. [ Bug #110616 ] source file stays open after parsing is done (PR#209)

* Spelling fixes supplied by Rob W. W. Hooft. All these are fixes in eitherThomas Wouters2000-07-161-1/+1
| | | | | | | | | | comments, docstrings or error messages. I fixed two minor things in test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't"). There is a minor style issue involved: Guido seems to have preferred English grammar (behaviour, honour) in a couple places. This patch changes that to American, which is the more prominent style in the source. I prefer English myself, so if English is preferred, I'd be happy to supply a patch myself ;)

* Vladimir Marangozov's long-awaited malloc restructuring.Guido van Rossum2000-05-031-2/+2

(This is not exactly what Vladimir posted to the patches list; I've made a few changes, and Vladimir sent me a fix in private email for a problem that only occurs in debug mode. I'm also holding back on his change to main.c, which seems unnecessary to me.)

The hacky heuristic for determining whether we have our *own* DOS box (due to Mark Hammond) is to test whether we're on line zero...
