From 506cb021d62e643fba38ddb4b84572a86cb3a3ba Mon Sep 17 00:00:00 2001 From: Julian Andres Klode Date: Mon, 13 Apr 2009 18:27:43 +0200 Subject: * python/tag.cc: Support 'key in mapping' for TagSections Support the replacement of mapping.has_key() for sections, and update the usage in apt/package.py and apt/debfile accordingly. This is implemented by extending the TagSecType with sequence methods, but only settings the contains method there. The TagSecGetAttr() function has been removed and replaced by the use of the tp_methods slot. --- python/apt_pkgmodule.cc | 4 ++++ python/tag.cc | 47 +++++++++++++++++++++++++++++++---------------- 2 files changed, 35 insertions(+), 16 deletions(-) (limited to 'python') diff --git a/python/apt_pkgmodule.cc b/python/apt_pkgmodule.cc index 86732781..34669fd5 100644 --- a/python/apt_pkgmodule.cc +++ b/python/apt_pkgmodule.cc @@ -472,6 +472,10 @@ static void AddInt(PyObject *Dict,const char *Itm,unsigned long I) extern "C" void initapt_pkg() { + // Finalize our types to add slots, etc. + if (PyType_Ready(&TagSecType) == -1) return; + + // Initialize the module PyObject *Module = Py_InitModule("apt_pkg",methods); PyObject *Dict = PyModule_GetDict(Module); diff --git a/python/tag.cc b/python/tag.cc index 217be290..cab32370 100644 --- a/python/tag.cc +++ b/python/tag.cc @@ -174,6 +174,16 @@ static PyObject *TagSecExists(PyObject *Self,PyObject *Args) return Py_BuildValue("i",1); } +static int TagSecContains(PyObject *Self,PyObject *Arg) +{ + char *Name = PyString_AsString(Arg); + const char *Start; + const char *Stop; + if (GetCpp(Self).Find(Name,Start,Stop) == false) + return 0; + return 1; +} + static char *doc_Bytes = "Bytes() -> integer"; static PyObject *TagSecBytes(PyObject *Self,PyObject *Args) { @@ -365,36 +375,41 @@ static PyMethodDef TagSecMethods[] = {} }; -// TagSecGetAttr - Get an attribute - variable/method /*{{{*/ -// --------------------------------------------------------------------- -/* */ -static PyObject *TagSecGetAttr(PyObject *Self,char *Name) -{ - return Py_FindMethod(TagSecMethods,Self,Name); -} - /*}}}*/ -// Type for a Tag Section + +PySequenceMethods TagSecSeqMeth = {0,0,0,0,0,0,0,TagSecContains,0,0}; PyMappingMethods TagSecMapMeth = {TagSecLength,TagSecMap,0}; PyTypeObject TagSecType = { PyObject_HEAD_INIT(&PyType_Type) - 0, // ob_size - "TagSection", // tp_name + 0, // ob_size + "TagSection", // tp_name sizeof(TagSecData), // tp_basicsize 0, // tp_itemsize // Methods TagSecFree, // tp_dealloc - 0, // tp_print - TagSecGetAttr, // tp_getattr + 0, // tp_print + 0, // tp_getattr 0, // tp_setattr 0, // tp_compare 0, // tp_repr 0, // tp_as_number - 0, // tp_as_sequence + &TagSecSeqMeth, // tp_as_sequence &TagSecMapMeth, // tp_as_mapping 0, // tp_hash - 0, // tp_call - TagSecStr, // tp_str + 0, // tp_call + TagSecStr, // tp_str + 0, // tp_getattro + 0, // tp_setattro + 0, // tp_as_buffer + Py_TPFLAGS_DEFAULT, // tp_flags + "TagSection Object", // tp_doc + 0, // tp_traverse + 0, // tp_clear + 0, // tp_richcompare + 0, // tp_weaklistoffset + 0, // tp_iter + 0, // tp_iternext + TagSecMethods // tp_methods }; // Method table for the Tag File object -- cgit v1.2.3
