| 7 # This perl script checks for correct memory function usage in ICU library code. | |
| 8 # It works with Linux builds of ICU using gcc. | |
| 9 # | |
| 10 # To run it, | |
| 11 # 1. Build ICU | |
| 12 # 2. cd icu/source | |
| 13 # 3. perl ICUMemCheck.pl | |
| 14 # | |
| 15 # All object files containing direct references to C or C++ runtime library memory | |
| 16 # functions will be listed in the output. | |
| 17 # | |
| 18 # For ICU 3.6, the expected output is | |
| 19 # common/uniset.o U operator delete(void*) | |
| 20 # common/unifilt.o U operator delete(void*) | |
| 21 # common/cmemory.o U malloc | |
| 22 # common/cmemory.o U free | |
| 23 # i18n/strrepl.o U operator delete(void*) | |
| 24 # layout/LEFontInstance.o U operator delete(void*) | |
| 25 # layout/LEGlyphStorage.o U operator delete(void*) | |
| 26 # layout/LayoutEngine.o U operator delete(void*) | |
| 27 # | |
| 28 # cmemory.c Expected failures from uprv_malloc, uprv_free implementation. | |
| 29 # uniset.cpp Fails because of SymbolTable::~SymbolTable() | |
| 30 # unifilt.cpp Fails because of UnicodeMatcher::~UnicodeMatcher() | |
| 31 # strrepl.cpp Fails because of UnicodeReplacer::~UnicodeReplacer() | |
| 32 # LayoutEngine.cpp Fails because of LEGlyphFilter::~LEGlyphFilter() | |
| 33 # LEGlyphStorage.cpp Fails because of LEInsertionCallback::~LEInsertionCallback() | |
| 34 # LEFontInstance.cpp Fails because of LECharMapper::~LECharMapper | |
| 35 # | |
| 36 # To verify that no additional problems exist in the .cpp files, #ifdef out the | |
| 37 # offending destructors, rebuild icu, and re-run the tool. The problems should | |
| 38 # be gone. | |
| 39 # | |
| 40 # The problem destructors all are for mix-in style interface classes. | |
| 41 # These classes can not derive from UObject or UMemory because of multiple-inheritance | |
| 42 # problems, so they don't get the ICU memory functions. The delete code | |
| 43 # in the destructors will never be called because stand-alone instances of | |
| 44 # the classes cannot exist. | |
| 45 # | |
