* ZipFile.close(): Kill the other struct.pack deprecationTim Peters2006-07-311-1/+1
| | | | | | | | | warning on Windows. Afraid I can't detect a pattern to when the pack formats decide to use a signed or unsigned format code -- appears nearly arbitrary to my eyes. So I left all the pack formats alone and changed the special-case data values instead.

| | | | | | | | | | | warnings on Win32. Also added an XXX about the line: pos3 = self.fp.tell() `pos3` is never referenced, and I have no idea what the code intended to do instead.

| | | | | | | | | (Contributed by Steven Taschuk) Replaces a bare except that caused all errors to be mis-reported as archive errors. Added a related NEWS item.

* SF patch #755987 (Jim Ahlstrom):Greg Ward2003-06-181-16/+15
| | | | | | | | | | | | | | | | | This is a patch for Bug 755031: If a null byte appears in a file name, Python zipfile.py retains it, but InfoZip terminates the name. Null bytes in file names are used as a trick by viruses. I tested WinZip, and it also truncates the file name at the null byte. The patch also fixes a buglet: If a zipfile incorrectly uses a directory separator other than '/', there was an invalid complaint that the central directory name does not match the file header name. I also removed my name from the top of the file. It was there for legal reasons which I believe no longer apply. Many people have worked on this file besides me.
* Patch #661719: Expose compilation errors as exceptions on request.Martin v. Löwis2003-01-151-1/+4
|
* Patch #651621, approved by MvL.Just van Rossum2002-12-121-2/+9
| | | | | | | | | | | | | | | | This patch allows ZipFile.writestr() to be called with an archive file name instead of a ZipInfo instance: z = ZipFile("myarchive.zip", "w") z.writestr("foo/baz/file.ext", data) z.close() I found the old writestr() method very inconvenient for simple (but common) things. If called with a file name instead of a ZipInfo instance, the date_time is set to the current date/time, which makes sense to me for anonymous data.

This partially applies SF patch http://www.python.org/sf/562373 (with basestring instead of string). (It excludes the changes to unittest.py and does not change the os.stat stuff.)

* SF bug #488514: -Qnew needs workTim Peters2001-12-061-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Big Hammer to implement -Qnew as PEP 238 says it should work (a global option affecting all instances of "/"). pydebug.h, main.c, pythonrun.c: define a private _Py_QnewFlag flag, true iff -Qnew is passed on the command line. This should go away (as the comments say) when true division becomes The Rule. This is deliberately not exposed to runtime inspection or modification: it's a one-way one-shot switch to pretend you're using Python 3. ceval.c: when _Py_QnewFlag is set, treat BINARY_DIVIDE as BINARY_TRUE_DIVIDE. test_{descr, generators, zipfile}.py: fiddle so these pass under -Qnew too. This was just a matter of s!/!//! in test_generators and test_zipfile. test_descr was trickier, as testbinop() is passed assumptions that "/" is the same as calling a "__div__" method; put a temporary hack there to call "__truediv__" instead when the method name is "__div__" and 1/2 evaluates to 0.5. Three standard tests still fail under -Qnew (on Windows; somebody please try the Linux tests with -Qnew too! Linux runs a whole bunch of tests Windows doesn't): test_augassign test_class test_coercion I can't stay awake longer to stare at this (be my guest). Offhand cures weren't obvious, nor was it even obvious that cures are possible without major hackery. Question: when -Qnew is in effect, should calls to __div__ magically change into calls to __truediv__? See "major hackery" at tail end of last paragraph <wink>.
* SF bug 486480: zipfile __del__ is brokenTim Peters2001-11-281-3/+3
| | | | | | ZipFile.__del__(): call ZipFile.close(), like its docstring says it does. ZipFile.close(): allow calling more than once (as all file-like objects in Python should support).

Change the computation of the ZipInfo.file_offset field to use the length of the relevant "extra" field -- there are two different ones, and the wrong one had been used. ;-( This closes SF tracker patch #403276, but more verbosely than the proposed patch.
