| michael@0 | 7 | # This perl script checks for correct memory function usage in ICU library code. |
| michael@0 | 8 | # It works with Linux builds of ICU using gcc. |
| michael@0 | 9 | # |
| michael@0 | 10 | # To run it, |
| michael@0 | 11 | # 1. Build ICU |
| michael@0 | 12 | # 2. cd icu/source |
| michael@0 | 13 | # 3. perl ICUMemCheck.pl |
| michael@0 | 14 | # |
| michael@0 | 15 | # All object files containing direct references to C or C++ runtime library memory |
| michael@0 | 16 | # functions will be listed in the output. |
| michael@0 | 17 | # |
| michael@0 | 18 | # For ICU 3.6, the expected output is |
| michael@0 | 19 | # common/uniset.o U operator delete(void*) |
| michael@0 | 20 | # common/unifilt.o U operator delete(void*) |
| michael@0 | 21 | # common/cmemory.o U malloc |
| michael@0 | 22 | # common/cmemory.o U free |
| michael@0 | 23 | # i18n/strrepl.o U operator delete(void*) |
| michael@0 | 24 | # layout/LEFontInstance.o U operator delete(void*) |
| michael@0 | 25 | # layout/LEGlyphStorage.o U operator delete(void*) |
| michael@0 | 26 | # layout/LayoutEngine.o U operator delete(void*) |
| michael@0 | 27 | # |
| michael@0 | 28 | # cmemory.c Expected failures from uprv_malloc, uprv_free implementation. |
| michael@0 | 29 | # uniset.cpp Fails because of SymbolTable::~SymbolTable() |
| michael@0 | 30 | # unifilt.cpp Fails because of UnicodeMatcher::~UnicodeMatcher() |
| michael@0 | 31 | # strrepl.cpp Fails because of UnicodeReplacer::~UnicodeReplacer() |
| michael@0 | 32 | # LayoutEngine.cpp Fails because of LEGlyphFilter::~LEGlyphFilter() |
| michael@0 | 33 | # LEGlyphStorage.cpp Fails because of LEInsertionCallback::~LEInsertionCallback() |
| michael@0 | 34 | # LEFontInstance.cpp Fails because of LECharMapper::~LECharMapper |
| michael@0 | 35 | # |
| michael@0 | 36 | # To verify that no additional problems exist in the .cpp files, #ifdef out the |
| michael@0 | 37 | # offending destructors, rebuild icu, and re-run the tool. The problems should |
| michael@0 | 38 | # be gone. |
| michael@0 | 39 | # |
| michael@0 | 40 | # The problem destructors all are for mix-in style interface classes. |
| michael@0 | 41 | # These classes can not derive from UObject or UMemory because of multiple-inheritance |
| michael@0 | 42 | # problems, so they don't get the ICU memory functions. The delete code |
| michael@0 | 43 | # in the destructors will never be called because stand-alone instances of |
| michael@0 | 44 | # the classes cannot exist. |
