2011-12-02Iron out bugs in Win64 found in daily buildsPatrik Nyblom
Almost all uses of the 'long' datatype is removed from VM and tests Emulator test now runs w/o drivers crashing Nasty abs bug fixed in VM as well as type errors in allocator debug functions Still one allocator test that fails, domain knowledge is needed to fix that. Fix type inconsistency in beam_load causing crashes

Still does not run, just compiles.

* jr/windows-file-append: Fix appending to large files (>4GB) on Windows OTP-8958
2010-10-14Add Win32 support for hard and symbolic file system linksBlaine Whittle
Hard linking requires XP or later and a NTFS formatted drive. Symbolic linking requires Windows Vista, Windows Server 2008, Windows 7 or later. Symbolic linking on earlier versions of Windows will return {error, enotsup}. file:make_link/2, file:make_sym_link/2 and file:read_link/1 are all implemented. file:read_file_info/1 does NOT return the number of hard links on the file as this results in performance problems for read_file_info/1, however this can be enabled by uncommenting a few lines of code. The original path was submitted on 9/2/2009 by Alex Tearse-Doyle.
2010-09-30Fix appending to large files (>4GB) on WindowsJuhani Rankimies
Append mode doesn't work for files larger that 4GB on Windows. Caused by incorrect usage of SetFilePointer in win_efile.c. Fix uses OVERLAPPED structure to specify write position (EOF). http://msdn.microsoft.com/en-us/library/aa365747.aspx Opening file in append mode was also considered, but rejected, because it might cause backwards incompatibility by limiting applicable operations on the descriptor. SetFilePointerEx was not used because it would caused more system calls than using OVERLAPPED structure.
2010-08-17erts: Remove the unused mem_drv driverBjörn Gustavsson
The mem_drv driver was only useful when elib_malloc was active.
2010-06-04Support opening files in exclusive modeMichael Santos
Add an option that atomically tests for the existence of a file and creates it if the file does not exist, by passing the O_EXCL flag to open() on Unix and CREATE_NEW flag on Windows. Support for O_EXCL varies across platforms and filesystems. {ok, Fd} = file:open("/tmp/foo", [write,exclusive]), {error, eexist} = file:open("/tmp/foo", [write,exclusive]).

2010-05-24Merge branch 'fm/file-operations' into devErlang/OTP
* fm/file-operations: Update preloaded modules Add file:advise/4 - a wrapper to the POSIX syscall posix_fadvise Add file:datasync/1 for syncing file contents only sys.h: Correct the get_int64() macro OTP-8637 fm/file-operations The functions file:advise/4 and file:datasync/1 have been added. (Thanks to Filipe David Manana.)
2010-05-20Add file:advise/4 - a wrapper to the POSIX syscall posix_fadviseFilipe David Manana
Useful for informing the Operating System about the access pattern for a file's data, so that it can adapt the caching strategy to maximize disk IO performance.
2010-05-20Add file:datasync/1 for syncing file contents onlyFilipe David Manana
file:datasync/1 invokes the POSIX system call "int fdatasync(int fd)". This system call is similar to "fsync" but, unlike fsync, it does not update the metadata associated with the file (like the access time for example). It's used by many DBMSs (MySQL and SQLite of example) to increase disk IO performance, as it avoids disk seeks and disk write operations compared to fsync. More details on it at: http://linux.die.net/man/2/fdatasync An example, from the MySQL source: http://bazaar.launchpad.net/~mysql/mysql-server/mysql-5.1-telco-6.1/annotate/head%3A/mysys/my_sync.c#L61 This new function just calls fsync on systems not implementing fdatasync.
