* * mpzmodule.c: cast some methods to the proper type.Guido van Rossum1993-12-171-1/+0
| | | | | | | * traceback.c (tb_print): use sys.tracebacklimit as a maximum number of traceback entries to print (default 1000). * ceval.c (printtraceback): Don't print stack trace header -- this is now done by tb_print().
* * mpzmodule.c: removed redundant mpz_print function.Guido van Rossum1993-11-051-6/+7
| | | | | | | | | | | | | | * object.[ch], bltinmodule.c, fileobject.c: changed str() to call strobject() which calls an object's __str__ method if it has one. strobject() is also called by writeobject() when PRINT_RAW is passed. * ceval.c: rationalize code for PRINT_ITEM (no change in function!) * funcobject.c, codeobject.c: added compare and hash functionality. Functions with identical code objects and the same global dictionary are equal. Code objects are equal when their code, constants list and names list are identical (i.e. the filename and code name don't count). (hash doesn't work yet since the constants are in a list and lists can't be hashed -- suppose this should really be done with a tuple now we have resizetuple!)
* * ceval.c, longobject.c, methodobject.c, listnode.c, arraymodule.c,Guido van Rossum1993-11-011-0/+1
| | | | | | pythonrun.c: added static forward declarations * pythonrun.h, ceval.h, longobject.h, node.h: removed declarations of static routines
* Several optimizations and speed improvements.Sjoerd Mullender1993-10-221-7/+5
| | | | cstubs: Use Matrix type instead of float[4][4].
* * bltinmodule.c: removed exec() built-in function.Guido van Rossum1993-10-181-0/+78
| | | | | | | * Grammar: add exec statement; allow testlist in expr statement. * ceval.c, compile.c, opcode.h: support exec statement; avoid optimizing locals when it is used * fileobject.{c,h}: add getfilename() internal function.
* * Makefile: added all: and default: targets.Guido van Rossum1993-07-051-1/+1
| | | | | | | | | | | | * many files: made some functions static; removed "extern int errno;". * frozenmain.c: fixed bugs introduced on 24 June... * flmodule.c: remove 1.5 bw compat hacks, add new functions in 2.2a (and some old functions that were omitted). * timemodule.c: added MSDOS floatsleep version . * pgenmain.c: changed exit() to goaway() and added defn of goaway(). * intrcheck.c: add hack (to UNIX only) so interrupting 3 times will exit from a hanging program. The second interrupt prints a message explaining this to the user.
* * pythonmain.c: -k option, usage message, more environment flags.Guido van Rossum1993-06-241-0/+8
| | | | | | | | | | | (the latter also in frozenmain.c) * ceval.c: global 'killprint' flag raises exception when printing an expression statement's value (useful for finding stray output) * timemodule.c: add asctime() and ctime(). Change julian date to 1-based origin (as intended and documented). * Removed unused DO_TIMES stuff from timemodule.c. Added 'epoch' and 'day0' globals (year where time.time() == 0 and day of the week the epoch started).
* * Added gmtime/localtime/mktime and SYSV timezone globals to timemodule.c.Guido van Rossum1993-06-171-0/+2
| | | | | | | | | | Added $(SYSDEF) to its build rule in Makefile. * cgensupport.[ch], modsupport.[ch]: removed some old stuff. Also changed files that still used it... And made several things static that weren't but should have been... And other minor cleanups... * listobject.[ch]: add external interfaces {set,get}listslice * socketmodule.c: fix bugs in new send() argument parsing. * sunaudiodevmodule.c: added flush() and close().
* * classobject.c: in instance_getattr, don't make a method out of aGuido van Rossum1993-05-251-19/+31
| | | | | | | | | | function found as instance data. * socketmodule.c: added 'flags' argument sendto/recvfrom, rewrite argument parsing in send/recv. * More changes related to access (terminology change: owner instead of class; allow any object as owner; local/global variables are owned by their dictionary, only class/instance data is owned by the class; "from...import *" now only imports objects with public access; etc.)
* * Lots of small changes related to access.Guido van Rossum1993-05-211-8/+49
| | | | | | | * Added "access *: ...", made access work for class methods. * Introduced subclass check: make sure that when calling ClassName.methodname(instance, ...), the instance is an instance of ClassName or of a subclass thereof (this might break some old code!)
* Access checks now work, at least for instance data (not for methodsGuido van Rossum1993-05-201-52/+75
| | | | | | | yet). The class is now passed to eval_code and stored in the current frame. It is also stored in instance method objects. An "unbound" instance method is now returned when a function is retrieved through "classname.funcname", which when called passes the class to eval_code.
* Several changes in one:Guido van Rossum1993-05-191-62/+151
| | | | | | | | | | | | | | | | (1) dictionaries/mappings now have attributes values() and items() as well as keys(); at the C level, use the new function mappinggetnext() to iterate over a dictionary. (2) "class C(): ..." is now illegal; you must write "class C: ...". (3) Class objects now know their own name (finally!); and minor improvements to the way how classes, functions and methods are represented as strings. (4) Added an "access" statement and semantics. (This is still experimental -- as long as you don't use the keyword 'access' nothing should be changed.)
* * pythonrun.c: Print exception type+arg *after* stack trace instead ofGuido van Rossum1993-05-121-24/+0
| | | | | | | before it. * ceval.c, object.c: moved testbool() to object.c (now extern visible) * stringobject.c: fix bugs in and rationalize string resize in formatstring() * tokenizer.[ch]: fix non-working code for lines longer than BUFSIZ
* (I suggest a recompile after getting this, the ceval.c bugfix may be crucial!)Guido van Rossum1993-04-151-5/+14
| | | | | | | * Makefile: removed superfluous AR=ar, fixed misleading comment. * ceval.c: fixed debugging code; save/restore errors in locals_2_fast. * intrcheck.c: for SunOS etc., turn off syscall resumption. * regexpr.h: bump number of registers to 100.
* * Microscopic corrections to make things compile on the Cray APP.Guido van Rossum1993-04-071-2/+1
| | | | | * Removed one use of $> in Makefile and warned about others. Added configurable lines in Makefile to change CC and AR.
* * Fixed some subtleties with fastlocals. You can no longer accessGuido van Rossum1993-03-301-9/+44
| | | | | | | | | | | | | | | | | | f_fastlocals in a traceback object (this is a core dump hazard if there are <nil> entries), but instead eval_code() merges the fast locals back into the locals dictionary if it looks like the local variables will be retained. Also, the merge routines save exceptions since this is sometimes needed (alas!). * Added id() to bltinmodule.c, which returns an object's address (identity). Useful to walk arbitrary data structures containing cycles. * Added compile() to bltinmodule.c and compile_string() to pythonrun.[ch]: support to exec/eval arbitrary code objects. The code that defaults globals and locals is moved from run_node in pythonrun.c (which is now identical to eval_node) to eval_code in ceval.c. [XXX For elegance a clean-up session is necessary.]
* Changes to speed up local variables enormously, by avoiding dictionaryGuido van Rossum1993-03-301-11/+125
| | | | | | lookup (opcode.h, ceval.[ch], compile.c, frameobject.[ch], pythonrun.c, import.c). The .pyc MAGIC number is changed again. Added get_menu_text to flmodule.
* * Changed all copyright messages to include 1993.Guido van Rossum1993-03-291-7/+25
| | | | | | | | | | | | | | | | | * Stubs for faster implementation of local variables (not yet finished) * Added function name to code object. Print it for code and function objects. THIS MAKES THE .PYC FILE FORMAT INCOMPATIBLE (the version number has changed accordingly) * Print address of self for built-in methods * New internal functions getattro and setattro (getattr/setattr with string object arg) * Replaced "dictobject" with more powerful "mappingobject" * New per-type functio tp_hash to implement arbitrary object hashing, and hashobject() to interface to it * Added built-in functions hash(v) and hasattr(v, 'name') * classobject: made some functions static that accidentally weren't; added __hash__ special instance method to implement hash() * Added proper comparison for built-in methods and functions
* * Changed many files to use mkvalue() instead of newtupleobject().Guido van Rossum1993-03-161-0/+3
| | | | | | | | | | * Fixcprt.py: added [-y file] option, do only files younger than file. * modsupport.[ch]: added vmkvalue(). * intobject.c: use mkvalue(). * stringobject.c: added "formatstring"; renamed string* to string_*; ceval.c: call formatstring for string % value. * longobject.c: close memory leak in divmod. * parsetok.c: set result node to NULL when returning an error.
* * ceval.c: ifdef out the last argument passing compat hack.Guido van Rossum1993-02-051-8/+6
| | | | | * Fixed memory leaks in socket, select and sv modules: mkvalue("O", v) does INCREF(v) so if v is brand new it should be XDECREF'd
* * Added Fixcprt.py: script to fix copyright message.Guido van Rossum1993-01-261-6/+4
| | | | | | | | | | | * various modules: added 1993 to copyright. * thread.c: added copyright notice. * ceval.c: minor change to error message for "+" * stdwinmodule.c: check for error from wfetchcolor * config.c: MS-DOS fixes (define PYTHONPATH, use DELIM, use osdefs.h) * Add declaration of inittab to import.h * sysmodule.c: added sys.builtin_module_names * xxmodule.c, xxobject.c: fix minor errors
* * Makefile: use cp -r to install the libraryGuido van Rossum1993-01-091-1/+1
| | | | | | | | * ceval.c: use #ifdef COMPAT_HACKS instead of #if 0 * Makefile: fix to make clmodule.c compile; make config.o dependent on libpython.a (so date is always correct) * timemodule.c: now sleep() also takes a float argument. * posixmodule.c: added nice().
* Various changes.Sjoerd Mullender1993-01-061-1/+1
| | | | | | | | | | | | | | | * Makefile: svmodule.c.proto and svgen.py are gone, svmodule.c came in their stead. Also, pass -DUSE_DL flag to thread.c and give the user a possibility to add the -DDEBUG to just thread.c. * ceval.c: init_save_thread() can be called more than once now. * svgen.py, svmodule.c.proto, svmodule.c: Removed prototype file and replaced it by the generated file. * thread.c: Added some more checks; added call to DL library when it is also used to tell it where the shared arena is so that DL can use some other area. * threadmodule.c: Call init_save_thread from another place. Also, added new function getlocklock() which does to lock objects what getfilefile does to file objects.
* * mymalloc.h: always allocate one extra byte, since some malloc'sGuido van Rossum1992-12-141-0/+4
| | | | | | | | | | | | | return NULL for malloc(0) or realloc(p, 0). (This should be done differently than wasting one byte, but alas...) * Moved "add'l libraries" option in Makefile to an earlier place. * Remove argument compatibility hacks (b) and (c). * Add grey2mono, dither2mono and mono2grey to imageop. * Dup the fd in socket.fromfd(). * Added new modules mpz, md5 (by JH, requiring GNU MP 1.2). Affects Makefile and config.c. * socketmodule.c: added socket.fromfd(fd, family, type, [proto]), converted socket() to use of getargs().
* * classobject.c: in instance_lenth, test result of call_objectGuido van Rossum1992-11-261-0/+2
| | | | | | for exception before using it. Fixed a few other places where the outcome of calling sq_length wasn't tested for exceptions (bltinmodule.c, ceval.c).
* * bltinmodule.c: added built-in function cmp(a, b)Guido van Rossum1992-10-181-0/+20
| | | | | | | | | | | | | | | * flmodule.c: added {do,check}_only_forms to fl's list of functions; and don't print a message when an unknown object is returned. * pythonrun.c: catch SIGHUP and SIGTERM to do essential cleanup. * Made jpegmodule.c smaller by using getargs() and mkvalue() consistently. * Increased parser stack size to 500 in parser.h. * Implemented custom allocation of stack frames to frameobject.c and added dynamic stack overflow checks (value stack only) to ceval.c. (There seems to be a bug left: sometimes stack traces don't make sense.)
* Modified most (but not yet all) I/O to always go through sys.stdout orGuido van Rossum1992-09-251-24/+24
| | | | | | sys.stderr or sys.stdin, and to work with any object as long as it has a write() (respectively readline()) methods. Some functions that took a FILE* argument now take an object* argument.
* Add some debugging features if DEBUG definedGuido van Rossum1992-09-031-0/+10
| | | | | (fetch the filename as a string so I can see it with dbx, and set f_lineno); call abort() when detecting an "undetected" error.

* * classobject.[ch], {float,long,int}object.c, bltinmodule.c:Guido van Rossum1992-08-141-7/+18
| | | | | | coercion is now completely generic. * ceval.c: for instances, don't coerce for + and *; * reverses arguments if left one is non-instance numeric and right one sequence.
* Changes so that user-defined classes can implement operations invokedGuido van Rossum1992-08-121-31/+75

* * Makefile: cosmeticsGuido van Rossum1992-08-051-27/+8
| | | | | | | | | | | | | | | | | | | | | | | | | * socketmodule.c: get rid of makepair(); fix makesocketaddr to fix broken recvfrom() * socketmodule: get rid of getStrarg() * ceval.h: move eval_code() to new file eval.h, so compile.h is no longer needed. * ceval.c: move thread comments to ceval.h; always make save/restore thread functions available (for dynloaded modules) * cdmodule.c, listobject.c: don't include compile.h * flmodule.c: include ceval.h * import.c: include eval.h instead of ceval.h * cgen.py: add forground(); noport(); winopen(""); to initgl(). * bltinmodule.c, socketmodule.c, fileobject.c, posixmodule.c, selectmodule.c: adapt to threads (add BGN/END SAVE macros) * stdwinmodule.c: adapt to threads and use a special stdwin lock. * pythonmain.c: don't include getpythonpath(). * pythonrun.c: use BGN/END SAVE instead of direct calls; also more BGN/END SAVE calls etc. * thread.c: bigger stack size for sun; change exit() to _exit() * threadmodule.c: use BGN/END SAVE macros where possible * timemodule.c: adapt better to threads; use BGN/END SAVE; add longsleep internal function if BSD_TIME; cosmetics
* * Makefile adapted to changes below.Guido van Rossum1992-08-041-3/+93
| | | | | | | | | | | * split pythonmain.c in two: most stuff goes to pythonrun.c, in the library. * new optional built-in threadmodule.c, build upon Sjoerd's thread.{c,h}. * new module from Sjoerd: mmmodule.c (dynamically loaded). * new module from Sjoerd: sv (svgen.py, svmodule.c.proto). * new files thread.{c,h} (from Sjoerd). * new xxmodule.c (example only). * myselect.h: bzero -> memset * select.c: bzero -> memset; removed global variable
