2013-01-25Extend char() to Unicode charactersHans Bolinder
The code related to the introduction of unicode_string() and unicode_char() has been removed. The types char() and string() have been extended to include Unicode characters. In fact char() was changed some time ago; this commit is about cleaning up the documentation and introduce better names for some functions.

2013-01-21Text representation of a float formatted using given options.Serge Aleynikov
This BIF solves a problem of float_to_list/1 that doesn't allow specifying the number of digits after the decimal point when formatting floats. float_to_list(Float, Options) -> string() Float = float() Options = [Option] Option = {decimals, Decimals::0..249} | {scientific, Decimals::0..249} | compact Returns a string which corresponds to the text representation of a `Float` formatted using given options. When decimals option is specified the returned value will contain at most `Decimals` number of digits past the decimal point. When `compact` option is provided the trailing zeros at the end of the list are truncated (this option is only meaningful together with the `decimals` option). When `scientific` option is provided, the float will be formatted using scientific notation with `Decimals` digits of precision. If `Options` is `[]` the function behaves like `float_to_list/1`. When using `decimals` option and the number doesn't fit in the static internal buffer of 256 bytes the function throws `badarg`.

2013-01-17Use share flags for all file operations on WindowsFilipe David Borba Manana
Some file operations provided by the Erlang file module didn't open the target file with all the file share flags. This made some concurrent file operations against the same file fail on Windows, while on other platforms such as GNU/Linux or Mac OS X they succeed. The operations will fail only if they're performed concurrently by different threads (async IO threads or scheduler threads). For example, one Erlang process does a file:delete/1 call while another Erlang process is doing a filelib:file_size/1 call. This made the former process get an eacces error from the file:delete/1 call. On GNU/Linux or Mac OS X the call would succeed. Another example is if one Erlang process attempts to open a file for reading while another one is in the middle of a file:read_file_info/1 call (after it opened the file and before it closed the file). It's easy to verify that if a file is not open with all the share flags, it's impossible for other threads (even if they belong to the same OS process) to open the file while the file is not closed by the first thread. The following test program shows this: #include <windows.h> #include <iostream> // Must be an existing file //#define SHARE_FLAGS (FILE_SHARE_READ) static DWORD WINAPI MyThreadFunction(LPVOID lpParam); static char *lastError(); int main(int argc, char *argv[]) { DWORD threadId; HANDLE threadHandle, hFile; hFile = CreateFile(FILENAME, GENERIC_READ, SHARE_FLAGS, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); if (hFile == INVALID_HANDLE_VALUE) { std::cerr << "File open error from main: " << lastError() << std::endl; return 1; } std::cout << "Main thread opened file successfully" << std::endl; threadHandle = CreateThread(NULL, 0, MyThreadFunction, NULL, 0, &threadId); if (threadHandle == INVALID_HANDLE_VALUE) { std::cerr << "Thread create error from main: " << lastError() << std::endl; return 1; } WaitForSingleObject(threadHandle, INFINITE); CloseHandle(threadHandle); CloseHandle(hFile); return 0; } static DWORD WINAPI MyThreadFunction( LPVOID lpParam ) { HANDLE hFile; hFile = CreateFile(FILENAME, GENERIC_READ, SHARE_FLAGS, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); if (hFile == INVALID_HANDLE_VALUE) { std::cerr << "File open error from second thread: " << lastError() << std::endl; return 1; } std::cout << "Second thread opened file successfully" << std::endl; CloseHandle(hFile); return 0; } static char *lastError() { static char *buf = NULL; DWORD dw = GetLastError(); if (buf != NULL) { LocalFree((LPTSTR) &buf); } FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS, NULL, dw, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR) &buf, 0, NULL); return buf; } Rnning this program with SHARE_FLAGS set to 0 (as efile_fileinfo() does for e.g.), shows that the second thread is unable to open the file: C:\cygwin\home\fdmanana\tmp>touch foo.bar C:\cygwin\home\fdmanana\tmp>threads_fopen_test.exe Main thread opened file successfully File open error from second thread: The process cannot access the file because it is being used by another process. Changing the program's SHARE_FLAGS to FILE_SHARE_READ, shows that both threads are able to open the file: C:\cygwin\home\fdmanana\tmp>touch foo.bar C:\cygwin\home\fdmanana\tmp>threads_test.exe Main thread opened file successfully Second thread opened file successfully Same logic applies to opening files for writing or deleting and renaming files while they're open by some other thread that didn't specify the flags FILE_SHARE_WRITE and FILE_SHARE_DELETE.

With silent rules, the output of make is less verbose and compilation warnings are easier to spot. Silent rules are disabled by default and can be disabled or enabled at will by make V=0 and make V=1.
