[PATCH] tools: Add gdbinit helper with LoadSymbolFiles command.
by Rémi Bernon Jan. 24, 2022

Jan. 24, 2022

To help gdb reload symbol files from /proc/<pid>/maps, making it possible to load debug info for ELF and PE modules for Wine processes. When sourced (from ~/.gdbinit for instance), this adds a new "load-symbol-files" command (with an "lsf" alias), which automatically calls add-symbol-file on every mapped file that can be read as ELF or PE, with the correct section offset. The command has to be run manually, for instance after executing for a while, to load new modules that may have been loaded, as there's no way for gdb to be notified of such changes automatically. Signed-off-by: Rémi Bernon <rbernon(a)codeweavers.com> --- This is some script I've been using for a while, and more or less broken versions are also used by other people, so I figured maybe it would be better to have a proper working version officially distributed with Wine source instead, as it's pretty useful for debugging Wine under gdb. It's still a bit manual to use, as gdb cannot easily be notified of dynamic library loading [1], but I think it's much better than having nothing. [1] in theory there's ways to do it using systemtap probes, but it's going to be hard to make it work, especially for PE modules. tools/gdbinit.py | 108 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 108 insertions(+) create mode 100644 tools/gdbinit.py diff --git a/tools/gdbinit.py b/tools/gdbinit.py new file mode 100644 index 00000000000..265d97722b7 --- /dev/null +++ b/tools/gdbinit.py @@ -0,0 +1,108 @@ +#!/bin/env python3 + +# Copyright 2021 Rémi Bernon for CodeWeavers +# +# This library is free software; you can redistribute it and/or +# modify it under the terms of the GNU Lesser General Public +# License as published by the Free Software Foundation; either +# version 2.1 of the License, or (at your option) any later version. +# +# This library is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

RFC: Reparse Point/NT Symlink Support [3]
by Erich E. Hoover Oct. 2, 2021

Oct. 2, 2021

I would love any and all feedback on updated versions of my "Reparse Point" patches, which are now available in staging: https://github.com/wine-staging/wine-staging/tree/master/patches/ntdll-Junc… Major changes since the last RFC version are: 1) Deletion of symlinks is now atomic (where supported). 2) Regular Unix symlinks are now reported as WSL Unix symlinks. 3) FILE_OPEN_REPARSE_POINT is now properly supported for applications that wish to access reparse points directly (symlink operations by file descriptor instead of by path). 4) Wine's cmd "dir" command now shows reparse point types and targets. 5) Wine's cmd "mklink" command now supports creating junction points and NT symlinks. 6) Absolute reparse points that are outside of the prefix no longer contain the path to drive Z (or appropriate drive letter). 7) Absolute reparse points now contain a string identifying the end of the Wine prefix that is used to modify the target path on file access if a prefix has been relocated (if the target is within the prefix). 8) Many, many bug fixes. Thank you in advance to those who look these patches over, and previous iterations, your feedback is greatly appreciated! I know that these patches have been a long time coming, but I believe that we're finally getting to a place where we've figured out all the gotchas. Hopefully other folks agree ;) === Context: For those of you that wonder "why do these patches exist?", I have been putting these together over the past few years for several reasons: 1) More modern Windows programs use NT symlinks to avoid duplicating files and taking up extra disk space (particularly .NET). 2) Wine currently has no mechanism to make symlinks on the "PE" side of the dividing line, these patches allow this for Windows file paths and a small additional patch (creating WSL Unix symlinks) allows the same behavior for Unix paths. 3) Wine currently takes up a lot of space with system DLLs that are duplicates of the system-wide files, a logical extension to these patches is a Wine-specific reparse tag that allows these system DLLs to be "copy-on-write" so that Wine prefixes don't take up unnecessary disk space. Please note that this feature is not a focus of the patchset (not included), as I would like to get the infrastructure in place before tackling that problem. Not currently supported: 1) Reparse points of type other than junction points, NT symlinks, and WSL Unix symlinks. 2) Creating WSL Unix symlinks. 3) Changing ownership permissions (lrwxrwxrwx) on the symlink instead of the target (currently a Linux limitation). Implementation overview: • Reparse points are implemented as Unix symlinks where relative symlinks always start with "./" and absolute symlinks start with "/". • Following the relative/absolute flag the 32-bit reparse point tag (junction point or NT symlink) is encoded as a relative path where each bit is encoded as "/" (0) or "./" (1). When creating WSL Unix symlinks (future feature) this tag encoding will be skipped. • For NT symlinks this is followed by a file/directory flag ("./" for directories, "/" for files) so that dangling symlinks can still be deleted properly with RemoveFile or RemoveDirectory (as appropriate). • After the reparse tag (and file/directory flag) the Unix path is then appended, relative paths are included unmodified and absolute paths have some minor modifications. • If the path is an absolute path and points outside the prefix then the portion of the path to drive Z (or appropriate drive letter) is removed. • If the path is an absolute path that points inside the prefix then after the prefix path an 8-bit 'P' is encoded the same way that the reparse point tag is ("/"=0, "./"=1). • If an absolute symlink is opened by the wineserver then the prefix path is checked (if appropriate) and if it doesn't match the path of the current Wine prefix then the symlink is modified to replace the old prefix path with the current prefix path. • Because reparse points involve a modification to an existing empty file/directory, symlink creation and "removal" is implemented by creating the symlink at a temporary location and then replacing the original with an atomic renameat2 call (on supported systems), equivalent call (BSD/Mac), or by unlinking the original and moving the symlink into place (for legacy systems that do not support atomic replacement). Best, Erich

[RFC PATCH 0/5] XAudio PE conversion.
by Rémi Bernon Sept. 22, 2021

Sept. 22, 2021

I'm sending this as an RFC for now as there's been some discussion already about how to handle PE dependencies. I think the approach I'm taking here, by including FAudio headers directly in the source and loading it dynamically is the easiest way, and the least disruptive for building and running Wine, if not the cleanest. All the other solutions have higher friction, either on third party packages, or on the system distribution. Upstream FAudio now has a pure Win32 backend, which makes it much easier to build as PE. This was never a requirement, and this series should work too with the SDL2 backend, as it tries to load Wine Mono SDL2 and FAudio as a fallback after trying from the prefix system libraries. It could help the transition though, and is going to be required anyway to support WMA decoding. Right now, with or without the Win32 backend, this would also introduce a functional regression as although supported by the new FAudio Win32 backend, it also depends on the WMA decoder MF transform to be implemented, which isn't the case yet in Wine. Cheers, Rémi Bernon (5): xactengine3_7: Move sources to xaudio2_7. xaudio2_7: Load FAudio dynamically. xaudio2_7: Import FAudio headers for private use. xaudio2_7: Build with msvcrt. xaudio2_7: Use msvcrt allocation functions. configure.ac | 55 - dlls/x3daudio1_0/Makefile.in | 4 +- dlls/x3daudio1_1/Makefile.in | 4 +- dlls/x3daudio1_2/Makefile.in | 4 +- dlls/x3daudio1_3/Makefile.in | 4 +- dlls/x3daudio1_4/Makefile.in | 4 +- dlls/x3daudio1_5/Makefile.in | 4 +- dlls/x3daudio1_6/Makefile.in | 4 +- dlls/x3daudio1_7/Makefile.in | 4 +- dlls/xactengine2_0/Makefile.in | 6 +- dlls/xactengine2_4/Makefile.in | 6 +- dlls/xactengine2_7/Makefile.in | 6 +- dlls/xactengine2_9/Makefile.in | 6 +- dlls/xactengine3_0/Makefile.in | 6 +- dlls/xactengine3_1/Makefile.in | 6 +- dlls/xactengine3_2/Makefile.in | 6 +- dlls/xactengine3_3/Makefile.in | 6 +- dlls/xactengine3_4/Makefile.in | 6 +- dlls/xactengine3_5/Makefile.in | 6 +- dlls/xactengine3_6/Makefile.in | 6 +- dlls/xactengine3_7/Makefile.in | 5 +- dlls/xapofx1_1/Makefile.in | 4 +- dlls/xapofx1_2/Makefile.in | 4 +- dlls/xapofx1_3/Makefile.in | 4 +- dlls/xapofx1_4/Makefile.in | 4 +- dlls/xapofx1_5/Makefile.in | 4 +- dlls/xaudio2_0/Makefile.in | 4 +- dlls/xaudio2_1/Makefile.in | 4 +- dlls/xaudio2_2/Makefile.in | 4 +- dlls/xaudio2_3/Makefile.in | 4 +- dlls/xaudio2_4/Makefile.in | 4 +- dlls/xaudio2_5/Makefile.in | 4 +- dlls/xaudio2_6/Makefile.in | 4 +- dlls/xaudio2_7/FAudio/F3DAudio.h | 262 ++++ dlls/xaudio2_7/FAudio/FACT.h | 814 ++++++++++ dlls/xaudio2_7/FAudio/FACT3D.h | 127 ++ dlls/xaudio2_7/FAudio/FAPO.h | 207 +++ dlls/xaudio2_7/FAudio/FAPOBase.h | 264 ++++ dlls/xaudio2_7/FAudio/FAPOFX.h | 178 +++ dlls/xaudio2_7/FAudio/FAudio.h | 1322 +++++++++++++++++ dlls/xaudio2_7/FAudio/FAudioFX.h | 308 ++++ dlls/xaudio2_7/Makefile.in | 4 +- dlls/xaudio2_7/compat.c | 92 +- dlls/xaudio2_7/faudio.c | 326 ++++ dlls/xaudio2_7/x3daudio.c | 35 +- .../xact_classes.idl | 0 dlls/{xactengine3_7 => xaudio2_7}/xact_dll.c | 182 ++- dlls/xaudio2_7/xapo.c | 29 +- dlls/xaudio2_7/xapofx.c | 21 +- dlls/xaudio2_7/xaudio_allocator.c | 2 - dlls/xaudio2_7/xaudio_dll.c | 267 ++-- dlls/xaudio2_7/xaudio_private.h | 149 +- dlls/xaudio2_8/Makefile.in | 4 +- dlls/xaudio2_9/Makefile.in | 4 +- 54 files changed, 4298 insertions(+), 505 deletions(-) create mode 100644 dlls/xaudio2_7/FAudio/F3DAudio.h create mode 100644 dlls/xaudio2_7/FAudio/FACT.h create mode 100644 dlls/xaudio2_7/FAudio/FACT3D.h create mode 100644 dlls/xaudio2_7/FAudio/FAPO.h create mode 100644 dlls/xaudio2_7/FAudio/FAPOBase.h create mode 100644 dlls/xaudio2_7/FAudio/FAPOFX.h create mode 100644 dlls/xaudio2_7/FAudio/FAudio.h create mode 100644 dlls/xaudio2_7/FAudio/FAudioFX.h create mode 100644 dlls/xaudio2_7/faudio.c rename dlls/{xactengine3_7 => xaudio2_7}/xact_classes.idl (100%) rename dlls/{xactengine3_7 => xaudio2_7}/xact_dll.c (87%) -- 2.31.0

[PATCH resend] ntdll: Implement JobObjectBasicProcessIdList for NtQueryInformationJobObject.
by Gabriel Ivăncescu Sept. 13, 2021

Sept. 13, 2021

Signed-off-by: Gabriel Ivăncescu <gabrielopcode(a)gmail.com> --- Resending as it fell off the list. Anything holding this up or anything I should improve on it? I realize the memcpy thing may be not ideal, but it avoids a pointless allocation + copy. Similar logic is done in user32's list_window_children, where it copies from user_handle_t to HWND in-place, but that can suffer from aliasing issues without memcpy since it's a different type, otherwise should compile to same code when optimized. But if that's not needed I can just use a direct assignment instead. Or is there something else about it that can be improved? dlls/kernel32/tests/process.c | 9 --------- dlls/ntdll/unix/sync.c | 31 ++++++++++++++++++++++++++++--- server/process.c | 34 ++++++++++++++++++++++++++++++++++ server/protocol.def | 9 +++++++++ 4 files changed, 71 insertions(+), 12 deletions(-) diff --git a/dlls/kernel32/tests/process.c b/dlls/kernel32/tests/process.c index e729bca..1c056fb 100644 --- a/dlls/kernel32/tests/process.c +++ b/dlls/kernel32/tests/process.c @@ -2700,15 +2700,11 @@ static void test_QueryInformationJobObject(void) pid_list->NumberOfProcessIdsInList = 42; ret = QueryInformationJobObject(job, JobObjectBasicProcessIdList, pid_list, FIELD_OFFSET(JOBOBJECT_BASIC_PROCESS_ID_LIST, ProcessIdList[1]), &ret_len); - todo_wine ok(!ret, "QueryInformationJobObject expected failure\n"); - todo_wine expect_eq_d(ERROR_MORE_DATA, GetLastError()); if (ret) { - todo_wine expect_eq_d(42, pid_list->NumberOfAssignedProcesses); - todo_wine expect_eq_d(42, pid_list->NumberOfProcessIdsInList); } @@ -2723,17 +2719,12 @@ static void test_QueryInformationJobObject(void) { ULONG_PTR *list = pid_list->ProcessIdList; - todo_wine ok(ret_len == FIELD_OFFSET(JOBOBJECT_BASIC_PROCESS_ID_LIST, ProcessIdList[2]), "QueryInformationJobObject returned ret_len=%u\n", ret_len); - todo_wine expect_eq_d(2, pid_list->NumberOfAssignedProcesses); - todo_wine expect_eq_d(2, pid_list->NumberOfProcessIdsInList); - todo_wine expect_eq_d(pi[0].dwProcessId, list[0]); - todo_wine expect_eq_d(pi[1].dwProcessId, list[1]); } } diff --git a/dlls/ntdll/unix/sync.c b/dlls/ntdll/unix/sync.c index a13e53a..0594a5e 100644 --- a/dlls/ntdll/unix/sync.c +++ b/dlls/ntdll/unix/sync.c @@ -791,11 +791,36 @@ NTSTATUS WINAPI NtQueryInformationJobObject( HANDLE handle, JOBOBJECTINFOCLASS c case JobObjectBasicProcessIdList: { JOBOBJECT_BASIC_PROCESS_ID_LIST *process = info; + DWORD count, i; if (len < sizeof(*process)) return STATUS_INFO_LENGTH_MISMATCH; - memset( process, 0, sizeof(*process) ); - if (ret_len) *ret_len = sizeof(*process); - return STATUS_SUCCESS; + + count = len - FIELD_OFFSET(JOBOBJECT_BASIC_PROCESS_ID_LIST, ProcessIdList); + count /= sizeof(process->ProcessIdList[0]); + + SERVER_START_REQ( query_job_pids ) + { + req->job = wine_server_user_handle(handle); + wine_server_set_reply(req, process->ProcessIdList, count * sizeof(process_id_t)); + if ((ret = wine_server_call(req)) != STATUS_SUCCESS) + return ret; + process->NumberOfAssignedProcesses = reply->count; + process->NumberOfProcessIdsInList = min(count, reply->count); + } + SERVER_END_REQ; + + if (sizeof(process_id_t) < sizeof(process->ProcessIdList[0])) + { + /* start from the end to not overwrite */ + for (i = process->NumberOfProcessIdsInList; i--;) + { + ULONG_PTR id = ((process_id_t*)(&process->ProcessIdList[0]))[i]; + memcpy(&process->ProcessIdList[i], &id, sizeof(id)); + } + } + + if (ret_len) *ret_len = (char*)(&process->ProcessIdList[process->NumberOfProcessIdsInList]) - (char*)process; + return count < process->NumberOfAssignedProcesses ?

[PATCH v3 0/5] Implement reflink support
by Alex Xu (Hello71) Sept. 9, 2021

Sept. 9, 2021

Over the years, Wine prefixes have gotten bigger and bigger, for a number of reasons. Creating a new Wine prefix for each application is still the current recommendation, as despite the best efforts of Wine developers, some applications still require system-wide workarounds. This leads to significant bloat for each application installed. With a MinGW build of Wine without Mono or Gecko, new 32-bit prefixes are over 150 MB, and new 64-bit prefixes are over 300 MB. The vast majority of these files are byte-for-byte identical to Wine's central DLL copies. This patch set implements reflink support in Wine via the copy_file_range syscall. The reasons for selecting copy_file_range over FICLONE are outlined in patch 2. A previous unpublished version of this patch set used FICLONERANGE, but it was less convenient to use from setupapi and has inferior system support. When reflink is supported by the underlying filesystem, new Wine prefix sizes with Mono and Gecko disabled are reduced to less than 1 MB. The resulting Wine prefix is byte-for-byte identical to one created without reflink, but occupies less space on disk. If hard links or symlinks were used, if an application such as winetricks writes to a system file, it would overwrite the central copy. With reflink, the file blocks will be transparently copied by the Linux kernel so that each Wine prefix can be independent. Some files cannot be deduplicated in the current Wine system, as they are dynamically generated during the Wine prefix installation process. These include 16-bit fake DLLs and manifest files. In theory, it should be possible to pre-generate these files, but considering the Wine prefix size is already reduced to less than 1 MB, the extra space savings are likely not worth the effort. Changes since v2: Fix/improve errno handling.
