Guido van Rossum [Sun, 18 Oct 1992 18:53:57 +0000 (18:53 +0000)]
* bltinmodule.c: added built-in function cmp(a, b)
* 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.)
Lots of little fixes.
- merged CloseCompressor and CloseDecompressor into one function
- keep existing errors in error function (for exceptions raised in the
Compress or Decompress callback functions)
- remove newline from error string generated by error function
- allocate less memory when compressing multiple frames
- keep existing errors when clCompress or clDecompress fails
- raise an exception when compressed data doesn't fit within
dataMaxSize bytes
- allocate frameSize bytes for decompression buffer instead of
dataMaxSize
- use mkvalue more often
- new function QueryParams which will accept CL.AUDIO and CL.VIDEO
args
- changed some function names
VFile: added new formats 'jpeg' and 'jpeggrey'. Decompression is done
using module 'jpeg' by the Displayer class. (Unfortunately it's too
slow for real time.) Print file size in printinfo() method.
Vinfo: added -t option (terse -- one line per file) and usage message.
Vtime: use BasicV{in,out}File classes -- the minimum needed.
Vmkjpeg, Vunjpeg: new utilities for jpeg (de)compression.
Modified most (but not yet all) I/O to always go through sys.stdout or
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.
New shell script Addmodule.sh makes it easier to add a new optional
module by editing Makefile and config.c in all the right places.
Used it to add most modules currently known. Added markers to help
the script to Makefile and config.c.
Changed the init() interface of LiveVideoOut to read out the window
size automatically -- the video is always centered. Added
resizevideo() and reshapewindow() interfaces. Documented all methods.
Changed Vsend/Vreceive to use the new interface. Allow window
resizing by the user in Vreceive.
New modules LiveVideo{In,Out} (interfaces will change!).
New programs V{send,receive} to send/receive video over UDP.
Comment typo changed in Vaddcache.
New module regsub contains sub(), gsub() and split() as in nawk.
string.splitfields(s, '') now returns [s] as split() in nawk.
Added _exit to exported functions of os.
* Makefile: added IMGFILE; moved some stuff around.
* flmodule.c: added some missing functions; changed readonly flags of
some data members based upon FORMS documentation.
* listobject.c: fixed int/long arg lint bug (bites PC compilers).
* several: removed redundant print methods (repr is good enough).
* posixmodule.c: added (still experimental) process group functions.
Added C++ support in thread.h; don't use signals if not strictly
necessary, and when they are, use SIGKILL; when compiled with -DDEBUG,
only print debug messages when "THREADDEBUG" is set in the environment.
VFile: The Entry-Indigo trick doesn't work on 4.0.1 hosts.
VFile: RandomVinFile can now write the cache to the file.
Vinfo: use the cached index if present and print a message whether it's there.
Added post_mortem() and pm() interfaces to pdb and wdb.
Added colorsys.py (color system conversions).
SV.py: new version for new svideo.h (Sjoerd).
DEVICE.py: added VIDEO event type.
Fixed "clear()" and added "clearto(r, g, b)".
Added class RandomVinFile which supports random access and warming the cache.
Added eofseen and errorseen methods to BasicVinFile.
Use RGB mode for rgb8 data on entry level Indigo.
Minor cosmetic changes.
Adapted the world to the new VFile.py. Fixed bugs in Vplay.py:
missing -n in help(), bogus frame skipping; and added patch for
weird time jumps. Removed colorsys.py (now in std library).
Fixed "sys.write" error in vcopy.py. Restructured README.
classobject.c moduleobject.c stdwinmodule.c xxobject.c:
raise AttributeError, not KeyError, when attribute deletion fails.
sunaudiodevmodule.c: check for deletion before calling setmember.
Use getargs() everywhere now. Standardize lay-out yet more (an ongoing
project :-). Change object administration: objects are removed from the
list of known objects as soon as their form is destroyed.
If a type has a repr function but no print function, printing it now
calls the repr function. When the refcount is bad, don't print
the object at all (chances of crashes).
Changes to checking and printing of references: the consistency
check is somewhat faster; don't print strings referenced once
(most occur in function's name lists).
Add some debugging features if DEBUG defined
(fetch the filename as a string so I can see it with dbx, and set f_lineno);
call abort() when detecting an "undetected" error.
Added a _v21 def to FL.py and added two new input field types
Added runcall(func, *args) interfaces to profile.py, bdb.py, pdb.py, wdb.py
Added new module bisect.py and used it in sched.py.
Mostly cosmetic changes to profile.py (changed output format).
Guido van Rossum [Tue, 25 Aug 1992 12:29:30 +0000 (12:29 +0000)]
Created Vedit.py, the video editor. This uses the classes in Viewer.py.
Viewer.py in turn requires changes to VFile.py (unfortunately that file
is now a complete mess...).
Guido van Rossum [Thu, 20 Aug 1992 11:51:47 +0000 (11:51 +0000)]
Added reopen() to VinFile with semantics of old rewind(); rewind() now
saves the cache.
Added getinfo() to VoutFile.
Fixed writing of 'grey' file header.
Added quiet parameter.
Adapted to new syntax.
