[PATCH 0/9] Beefing up tests for dbghelp
by Eric Pouech 12 Jul '21

12 Jul '21

The following series beefs up the tests about dbghelp DLL and fixes a couple of bugs in dbghelp. The idea is to have a set of files to get debug info from (debuggee*.*). This is supported in two different ways: A) to be compiled directly inside dbghelp_test: the default tools and options used in Wine will be covered (now: cross compile + dwarf version 2 debug format) B) but also the ability to run the same tests on an external process + image (made mainly out of the debuggee*.* only files). The idea is of course to use different compilers, debug format, options, 32/64bit targets... Those alternate images **ARE NOT** part (for now) of winetest. Unfortunately, with Winetest Bot, the A) won't work under windows: debug format of dbghelp_test.exe is dwarf2, while native dbghelp doesn't support it. So the tests are skipped. Anyway, most of the Windows setup:s don't have native dbghelp.dll installed <g>, so that shouldn't change much. I locally test every patch with: - A) on 32bit Wine (mingw + dwarf2) - A) on 64bit Wine (mingw + dwarf2) - A) on Windows10 as PE64 (msc + pdb) - B) image: mingw + dwarf2 + target=PE64bit + option -O1 on 64bit Wine - B) image: mingw + dwarf2 + target=PE32bit + option -O1 on 32bit Wine - B) image: ms compiler + pdb + target=PE64bit + option /O1 on 64 bit Wine This serie will be continued with: 1) more tests (and more fixes) (around 20+ patches to come) 2) support of dwarf3 and 4 (around 70+ patches to come) I also plan to add more local tests (dwarf3 and dwarf4; WoW; PE32 + pdb on Wine, cross 32/64 bit between tester and debuggee, other options O2). A+ --- Eric Pouech (9): dbghelp/tests: Added dedicated structure to control the debuggee dbghelp/tests: Added ability to launch an external process instead of debugging self dbghelp/tests: Now properly getting base of main module inside debuggee structure dbghelp/tests: Added two new compilation units (debuggee1.c and debuggee2.c) dbghelp/tests: now building inside each debuggee a manifest dbghelp/tests: StackWalk64 testing now support external process dbghelp/tests: Added tests about getting symbol information dbghelp: returns name of compiland in SymGetTypeInfo dbghelp: handling of complex location in dwarf dlls/dbghelp/dwarf.c | 1 - dlls/dbghelp/tests/Makefile.in | 4 +- dlls/dbghelp/tests/dbghelp.c | 505 +++++++++++++++++++++++++++++++-- dlls/dbghelp/tests/debuggee.h | 30 ++ dlls/dbghelp/tests/debuggee1.c | 115 ++++++++ dlls/dbghelp/tests/debuggee2.c | 7 + dlls/dbghelp/type.c | 3 +- 7 files changed, 644 insertions(+), 21 deletions(-) create mode 100644 dlls/dbghelp/tests/debuggee.h create mode 100644 dlls/dbghelp/tests/debuggee1.c create mode 100644 dlls/dbghelp/tests/debuggee2.c

[PATCH v5] crypt32: Implement CNG_RSA_PUBLIC_KEY_BLOB encoding/decoding
by Hans Leidekker 12 Jul '21

12 Jul '21

From: Aaron Hill <aa1ronham(a)gmail.com> v5: Remove ERR statements. Store the exponent as a byte array in the test and add todo_wine tests to make it clear that Wine should decode the exponent as 3 bytes instead of 4. Add support for the OID CNG_RSA_PUBLIC_KEY_BLOB to CryptEncodeObjectEx and CryptDecodeObjectEx. This OID decodes to / encodes from memory consisting of a BCRYPT_RSAKEY_BLOB, followed in memory by the exponent and modulus in big-endian format. This allows the Visual Studio 2019 web installer to progress further - it now reachs the stubbed NCryptOpenStorageProvider function. To aid in debugging similar issues, CryptEncodeObjectEx and CryptDecodeObjectEX now print a FIXME when encountering an unknown OID/struct type, instead of silently returning an error.

[PATCH v4] crypt32: Implement CNG_RSA_PUBLIC_KEY_BLOB encoding/decoding
by Aaron Hill 10 Jul '21

10 Jul '21

Add support for the OID CNG_RSA_PUBLIC_KEY_BLOB to CryptEncodeObjectEx and CryptDecodeObjectEx. This OID decodes to / encodes from memory consisting of a BCRYPT_RSAKEY_BLOB, followed in memory by the exponent and modulus in big-endian format. This allows the Visual Studio 2019 web installer to progress further - it now reachs the stubbed NCryptOpenStorageProvider function. To aid in debugging similar issues, CryptEncodeObjectEx and CryptDecodeObjectEX now print a FIXME when encountering an unknown OID/struct type, instead of silently returning an error.
