|
e1d593d9 | 2020-08-04 18:35:01 | Fix compilation with older environments This change should fix following compile error: dlfcn.c: In function 'dlsym': dlfcn.c:374:14: warning: implicit declaration of function 'GetModuleHandleExA' dlfcn.c: undefined reference to `GetModuleHandleExA' Documentation for function GetModuleHandleExA() says: To compile an application that uses this function, define _WIN32_WINNT as 0x0501 or later.

0a494c01 | 2020-07-15 08:07:53 | Merge pull request #74 from pali/master Replace VirtualQueryEx() call by GetModuleHandleExA() call | |
|
8ec5ffef | 2020-07-14 21:14:56 | Replace VirtualQueryEx() call by GetModuleHandleExA() call Usage of VirtualQueryEx() call is needed for retrieving HMODULE of passed function address and it is just an undocumented hack. Based on @rhabacker's tests it is unstable and does not work correctly. https://github.com/dlfcn-win32/dlfcn-win32/pull/72#issuecomment-656581418 So replace VirtualQueryEx() call by standard GetModuleHandleExA() function with special GET_MODULE_HANDLE_EX_FLAG_FROM_ADDRESS flag which should do the same thing but it is documented and it is working correctly. | |

32be0765 | 2020-02-22 13:54:54 | Merge pull request #68 from pali/master Show "(null)" in error message when passed filname to dlopen() was NULL and error occurred | |
|
70c5c20a | 2020-02-19 22:39:29 | Show "(null)" in error message when passed filname to dlopen() was NULL and error occurred It does not make sense to pass file variable (which is NULL) to function save_err_ptr_str() which converts its argument to string. We can call directly save_err_str() with string value. Also it is highly unexpected that GetModuleHandle(NULL) call fails. | |

|
ff302674 | 2019-07-26 18:21:30 | Fix more gcc warnings ISO C90 forbids mixed declarations and code ISO C++ forbids converting a string constant to 'char*' | |
|
2bb5f487 | 2019-07-25 20:34:46 | Fix gcc warning: ISO C forbids return between function pointer and void * Instead of using compiler specific pragma to disable particular warning, rewrite code which cast from function pointer to data pointer according to POSIX dlopen() documentation. This also fix compile warning under MSVC. According to the ISO C standard, casting between function pointers and 'void *', as done above, produces undefined results. POSIX.1-2003 and POSIX.1-2008 accepted this state of affairs and proposed the following workaround: *(void **) (&cosine) = dlsym(handle, "cos"); This (clumsy) cast conforms with the ISO C standard and will avoid any compiler warnings. | |
|
403b240f | 2019-07-25 20:34:28 | Fix gcc warning: comparison between signed and unsigned integer expressions GetTempPathA() returns DWORD (32/64bit unsigned integer) and not int (32 signed integer). | |
|
39ff58c2 | 2019-07-25 20:32:53 | Do not include intrin.h file Include file intrin.h is not needed for compiling dlfcn.c as _ReturnAddress intrinsic is defined in dlfcn.c manually. Moreover _ReturnAddress is available only as an intrinsic, there is no function implementation. So even including intrin.h file does not provide function variant for _ReturnAddress. More important, include file intrin.h is not available in older Windows Driver Kit 7.1.0. So removing usage of intrin.h file makes compilation of dlfcn-win32 also under these older WDK versions. | |

|

|

|
d9d49f2d | 2019-04-25 19:26:23 | Remove ifdef hack for snprintf() Old version of MSVC does not support snprintf() function and sprintf_s() is not replacement for C99 snprintf(). As the only usage of snprintf() is to format void* pointer we can use sprintf() with enough long buffer. | |
|
04bbf248 | 2019-04-25 18:18:31 | Simplify code around #ifdef UNICODE The whole dlfcn.h API works with char* (ANSI) strings. For WINAPI UNICODE builds it is still possible to call WINAPI ANSI functions with -A suffix. E.g. LoadLibraryExA() instead of LoadLibraryEx() or FormatMessageA() instead of FormatMessage(). This simplify whole implementation when compiling with UNICODE support as there is no need to do conversion from wchar_t to char and vice-versa. | |

278c782a | 2019-02-14 14:57:29 | Merge pull request #44 from pali/master Fix resolving global symbols and implement RTLD_DEFAULT and RTLD_NEXT | |
|
63d7bda4 | 2019-01-29 22:57:04 | Implement support for dlsym() with RTLD_DEFAULT and RTLD_NEXT dlsym() with RTLD_DEFAULT handle behaves in same way like with global handle returned by dlopen() with NULL file name. dlsym() with RTLD_NEXT handle search for next loaded module which provides specified symbol. "Next" means module which in EnumProcessModules() result after the module which called dlsym(). To get caller function of dlsym() use _ReturnAddress() intrinsic. To get module where is caller function use the fact that HMODULE is the same value as the module's base address. When compiling under gcc, defines _ReturnAddress() macro via gcc's builtin as it does not provide MSC's specific _ReturnAddress() intrinsic. Added tests demonstrate that both RTLD_DEFAULT and RTLD_NEXT are working as expected. | |
|
29c46a54 | 2019-01-29 22:38:42 | Fix resolving global symbols when LoadLibrary() is called after dlopen() Usage of first_automatic_object cache is wrong. This cache is filled by all loaded DLL files (either implicitly or explicitly with LoadLibrary() call) by EnumProcessModules() call at first usage of dlopen(). So dlsym() can resolve global symbols only if they were loaded prior to dlopen() call. Any future usage of LoadLibrary() does not include newly loaded DLLs into first_automatic_object cache. To fix this problem, first_automatic_object cache is fully removed and EnumProcessModules() call is issued directly in dlsym() call. As EnumProcessModules() returns all DLLs, included those which were loaded by dlopen() with RTLD_LOCAL, it may break RTLD_LOCAL support. To address this problem switch linked-list of all loaded DLLs with RTLD_GLOBAL to linked-list of all loaded DLLs with RTLD_LOCAL flag. And then skip modules from EnumProcessModules() which are in linked-list. Also in WinAPI all DLLs loaded by LoadLibrary() behaves like RTLD_GLOBAL. So above change is compatible with this behavior. There may be another problem. Before retrieving HMODULE for DLL filename (which is done by LoadLibrary()), it is not possible to detect if DLL was already loaded by RTLD_LOCAL or not. And after calling LoadLibrary() it is not possible to know if DLL was loaded either by dlsym() with RTLD_LOCAL or by LoadLibrary() (which is equivalent to RTLD_GLOBAL). To address this problem, compare number of loaded modules (counted by EnumProcessModules()) before and after LoadLibrary() called from dlsym(). If number does not change it means that DLL was already loaded. So based on this result either add or remove HMODULE from linked-list of RTLD_LOCAL modules. Added test demonstrate usage of: global = dlopen(NULL, RTLD_GLOBAL); /* global handle */ LoadLibrary("library.dll"); /* this provides function */ function = dlsym(global, "function"); /* resolve function from library.dll */ | |

5bcd8c53 | 2017-05-01 11:03:01 | Fix bug in dlerror second consecutive call According to the specs, a second consecutive call to dlerror should always return NULL . This was the case in dlfcn-win32 before https://github.com/dlfcn-win32/dlfcn-win32/pull/20 introduce a regression that caused dlerror to crash on the second consecutive call. In this commit the issue is fixed as suggested in https://github.com/dlfcn-win32/dlfcn-win32/issues/34 and a regression test has been added. | |
