I dug into this, and found that the failure happens here:
res = fh->link (newpath);
in the link() function of file src/winsup/cygwin/syscalls.cc. res is -1, and
errno == EEXIST at this point.
In the call above, newpath is:
/cygdrive/c/git/git/.git/objects/pack/pack-
d629a7029e3a941884c4bea2b33cc27e32f55779.pack
Digging further, this line fails:
if (CreateHardLinkA (newpc, pc, NULL))
goto success;
in function fhandler_disk_file::link(), fhandler_disk_file.cc. CreateHardLinkA
() returns 0, and GetLastError() returns 183 (ERROR_ALREADY_EXISTS: Cannot
create a file when that file already exists).
In the CreateHardLinkA() call above, newpc.get_win32() yields:
c:\git\git\.git\objects\pack\pack-d629a7029e3a941884c4bea2b33cc27e32f55779.pack
pc.get_win32() yields:
c:\git\git\.git\objects\tmp_pack_btsO9s
I know that the destination file (newpc) does not exist; so I am perplexed why
CreateHardLinkA() is failing. In the CreateHardLink() documentation on MSDN,
I see this comment:
"if you open a file that does not allow sharing, another application cannot
share the file by creating a new hard link to the file"
However, I see that all calls to CreateFile() in XP Cygwin happen with:
FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE
Any ideas why CreateHardLinkA() could still be failing?
Thanks,
MP
