[PATCH v2 01/21] block: Fixes nfs compiling error on msys2/mingw

[Yonggang Luo]

These compiling errors are fixed:
../block/nfs.c:27:10: fatal error: poll.h: No such file or directory
   27 | #include <poll.h>
      |          ^~~~~~~~

   63 |     blkcnt_t st_blocks;

../block/nfs.c: In function 'nfs_client_open':
../block/nfs.c:550:27: error: 'struct _stat64' has no member named 'st_blocks'
  550 |     client->st_blocks = st.st_blocks;

../block/nfs.c: In function 'nfs_get_allocated_file_size':
../block/nfs.c:751:41: error: 'struct _stat64' has no member named 'st_blocks'
  751 |     return (task.ret < 0 ? task.ret : st.st_blocks * 512);
      |                                         ^
../block/nfs.c: In function 'nfs_reopen_prepare':

  805 |         client->st_blocks = st.st_blocks;
      |                               ^
../block/nfs.c: In function 'nfs_get_allocated_file_size':
../block/nfs.c:752:1: error: control reaches end of non-void function [-Werror=return-type]
  752 | }
      | ^

On msys2/mingw, there is no st_blocks in struct _stat64, so we use consistence st_size instead.

[PATCH v2 02/21] ci: fixes msys2 build by upgrading capstone to 4.0.2

[Yonggang Luo]

The currently random version capstone have the following compiling issue:
  CC      /c/work/xemu/qemu/build/slirp/src/arp_table.o
make[1]: *** No rule to make target “/c/work/xemu/qemu/build/capstone/capstone.lib”。 Stop.

Subproject commit 1d230532840a37ac032c6ab80128238fc930c6c1 are the tagged version 4.0.2
when upgrading to this version, the folder structure of include are changed to
qemu\capstone\include
│  platform.h
│
├─capstone
│      arm.h
│      arm64.h
│      capstone.h
│      evm.h
│      m680x.h
│      m68k.h
│      mips.h
│      platform.h
│      ppc.h
│      sparc.h
│      systemz.h
│      tms320c64x.h
│      x86.h
│      xcore.h
│
└─windowsce
        intrin.h
        stdint.h

in capstone. so we need add extra include path -I${source_path}/capstone/include/capstone
for directly #include <capstone.h>, and the exist include path should preserve, because
in capstone code there something like #include "capstone/capstone.h"

[PATCH v2 03/21] configure: Fixes ncursesw detection under msys2/mingw and enable curses

[Yonggang Luo]

The mingw pkg-config are showing following absolute path and contains : as the separator,
so we must handling : properly.

-DNCURSES_WIDECHAR -I/usr/include/ncursesw -lncursesw
-DNCURSES_WIDECHAR -I/usr/include/ncursesw -lcursesw

msys2/mingw lacks the POSIX-required langinfo.h.

gcc test.c -DNCURSES_WIDECHAR -I/mingw64/include/ncursesw -pipe -lncursesw -lgnurx -ltre -lintl -liconv
test.c:4:10: fatal error: langinfo.h: No such file or directory
    4 | #include <langinfo.h>

So we using g_get_codeset instead of nl_langinfo(CODESET)

[PATCH v2 06/21] ci: Enable msys2 ci in cirrus

[Yonggang Luo]

Install msys2 in a proper way refer to https://github.com/cirruslabs/cirrus-ci-docs/issues/699
The https://wiki.qemu.org/Hosts/W32#Native_builds_with_MSYS2 need to be updated.
There is no need of --cross-prefix, open mingw64.exe instead of msys2.exe then we don't
need the --cross-prefix, besides we using environment variable settings:
    MSYS: winsymlinks:nativestrict
    MSYSTEM: MINGW64
    CHERE_INVOKING: 1
to opening mingw64 native shell.
We now running tests with make -i check to skip tests errors.

[PATCH v2 07/21] tests: Trying fixes test-replication.c on msys2/mingw.

[Yonggang Luo]

On Windows there is no path like /tmp/s_local_disk.XXXXXX
Use g_get_tmp_dir instead of /tmp.

[PATCH v2 08/21] tests: test-replication disable /replication/secondary/* on msys2/mingw.

[Yonggang Luo]

They cause failure on msys2/mingw, that's because file-win32.c not implement
.bdrv_reopen_prepare/commit/abort yet.

> Unexpected error in bdrv_reopen_prepare() at ../block.c:4191:

> files

Can you try to find out what reopen this is?

I assume it's for switching between read-write and read-only. In this
case an implementation of .bdrv_reopen_prepare/commit/abort that can do
this switch is required.

This is more serious development work, so I can't propose a quick fix.

Alternatively, we could just declare replication unsupported on Windows
and let configure make sure that CONFIG_REPLICATION is never set for it.

<stefanha> luoyonggang: That might be missing functionality in block/file-win32.c.
* davidgiluk yawns and looks up
<stefanha> luoyonggang: The block/file-posix.c block driver supports .bdrv_reopen_*()
while block/file-win32.c does not. It's probably because no one has tried to implement it.
<luoyonggang> OK, I got the direction,
<luoyonggang> Just need implement .bdrv_reopen_*() functions in file-win32.c

[PATCH v2 16/21] rcu: add uninit destructor for rcu

[Yonggang Luo]

This is necessary if the pending  rcu calls are closing and removing
temp files. This also provide a function
void rcu_wait_finished(void);
to fixes test-logging.c test failure on msys2/mingw.
On windows if the file doesn't closed, you can not remove it.

The original code would try  ncurses via pkg-config and if that failed, would
falback to pdcurses.

The new code tries ncursesw via pkg-config and then tries ncursesw again
via manually specified args, and doesn't try  ncurses or pdcurses at all.

This fixes your build as you've installed ncursesw, but breaks anyone
who was using ncurses or pdcurses previously. At least on Fedora only
pdcurses is available for mingw, so I don't think we should be dropping
this. It looks like we just need to check all three of ncursesw, ncurses
and pdcurses.

This still needs the changes discussed in v1 to remove all the
configure args and move the commands into the main cirrus.yml

Gotcha, Indeed   $pkg_config --cflags ncurses can find curses on mingw32,
the problem is onw mingw32 the include path
have :, so we can not use : as the path sepaerator, for cross-paltform
reason, which is best for path separator?

I presume msys is taking care of translating "/" into "\" so that
we don't need to use  g_build_filename to use the native directory
separator straightaway ?

We don't need to add IRC transscripts into the commit message. It
is sufficient to note that .bdrv_reopen* are not implemented on
in block/file-win32.c, which you already did at the start.

'checkpatch.pl' didn't complain about this.

With the line break

I guess it was using ":" because " " might be valid in the file path.

How about using "#" or "%" instead as those should be more unlikely to
clash.

That's not correct, doing that will cause compiling failure

So it looks like we have a test getting stuck. After this change is in
we could split the test execution out into its own script so to make
it more obvious if/when this happens - for example,

  script:
    - mkdir build
    - cd build
    - ../configure --enable-werror || { cat config.log; exit 1; }
    - gmake -j8
  test_script:
   - gmake V=1 check

I can follow up with a proper patch for that (and making the change
for macos as well) later.

What would help most is if there's a way to convince meson to print
the execution time of each test case, instead of merely its name.
That way we could immediately spot the slow test when it hits

NACK. st_blocks and st_size is not the same. st_blocks is the number of allocated blocks on disk. st_size is the virtual size of a file as it may contain holes.
I think the appropriate fix is to not implement nfs_get_allocated_file_size on WIN32. Its not mandatory.

It is definitely not. Where do you have this info from?

Please have a look at libnfs/lib/nfs_v3.c in function nfs3_stat_1_cb.


        st.st_size    = res->GETATTR3res_u.resok.obj_attributes.size;
#ifndef WIN32
        st.st_blksize = NFS_BLKSIZE;
	st.st_blocks  = (res->GETATTR3res_u.resok.obj_attributes.used + 512 - 1) / 512;
#endif//WIN32


Your patch will eliminate this difference for non WIN32 systems. Please change your patch to not implement nfs_get_allocated_file_size and qemu will handle this case properly.
