Re: [PATCH v3 0/5] Implement reflink support

by Fabian Maurer

Hello, first, thanks for working on this, would be a welcome improvement! Do I understand that right that it wouldn't work for ext4 and there's not really anything we could do to support it?

[PATCH] iphlpapi: Avoid use of uninitialized variable

In gateway_and_prefix_addresses_alloc prefix_len isn't set in the error case, but used unconditionally. Avoid this by initializing upon declaration. (Identified by GCC 12.)

[PATCH v3 1/5] ntdll: add support for IOCTL_COPYCHUNK.

by Alex Xu (Hello71)

This API really sucks; it literally just passes through the raw SMB request. However, there are some benefits over FSCTL_DUPLICATE_EXTENTS_TO_FILE: 1. it's easier to use from setupapi than FSCTL_DUPLICATE_EXTENTS_TO_FILE which can't plausibly be emulated. 2. on Windows, IOCTL_COPYCHUNK is already called (indirectly) from CopyFile on Windows. see e.g. https://www.ghisler.ch/board/viewtopic.php?t=43945. 3. copy_file_range allows kernel acceleration if reflink isn't possible. 4. copy_file_range is supported on FreeBSD. --- configure | 6 ++ configure.ac | 1 + dlls/ntdll/unix/file.c | 121 +++++++++++++++++++++++++++++++++++++++++ include/config.h.in | 3 + include/winioctl.h | 34 ++++++++++++ 5 files changed, 165 insertions(+) diff --git a/configure b/configure index 7760e43b8e9..78e502c28d6 100755 --- a/configure +++ b/configure @@ -19717,6 +19717,12 @@ esac ac_save_CFLAGS="$CFLAGS" CFLAGS="$CFLAGS $BUILTINFLAG" +ac_fn_c_check_func "$LINENO" "copy_file_range" "ac_cv_func_copy_file_range" +if test "x$ac_cv_func_copy_file_range" = xyes +then : + printf "%s\n" "#define HAVE_COPY_FILE_RANGE 1" >>confdefs.h + +fi ac_fn_c_check_func "$LINENO" "epoll_create" "ac_cv_func_epoll_create" if test "x$ac_cv_func_epoll_create" = xyes then : diff --git a/configure.ac b/configure.ac index 181047ef0d8..de2f810b4ac 100644 --- a/configure.ac +++ b/configure.ac @@ -1957,6 +1957,7 @@ dnl **** Check for functions **** ac_save_CFLAGS="$CFLAGS" CFLAGS="$CFLAGS $BUILTINFLAG" AC_CHECK_FUNCS(\ + copy_file_range \ epoll_create \ fstatfs \ futimens \ diff --git a/dlls/ntdll/unix/file.c b/dlls/ntdll/unix/file.c index a29b5cbb980..cedb57e8f2f 100644 --- a/dlls/ntdll/unix/file.c +++ b/dlls/ntdll/unix/file.c @@ -347,6 +347,7 @@ NTSTATUS errno_to_status( int err ) #ifdef ETIME /* Missing on FreeBSD */ case ETIME: return STATUS_IO_TIMEOUT;

[PATCH v3 0/5] Implement reflink support

by Alex Xu (Hello71)

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. v1->v2: Fix/improve errno handling. v2->v3: Rebase.
