The other failure of the non-blocking I/O on pipes test on mingw is because
when read() is called on a non-blocking pipe fd with an empty buffer, it
fails with EINVAL. Whereas POSIX says that it should fail with EAGAIN.
This fixes it, by adding a 'read' module for the function read() and overrides
of stdio functions like fgetc and fscanf.
2011-04-14 Bruno Haible <address@hidden>
Support non-blocking pipe I/O in read() on native Windows.
* lib/unistd.in.h: Include <sys/types.h> also for 'read'.
(read): New declaration.
* lib/read.c: New file.
* lib/stdio.in.h (_GL_ATTRIBUTE_FORMAT_SCANF,
_GL_ATTRIBUTE_FORMAT_SCANF_SYSTEM): New macros.
(fgetc, fgets, fread, fscanf, getc, getchar, gets, scanf, vfscanf,
vscanf): New declarations.
* lib/stdio-read.c: New file.
* m4/read.m4: New file.
* m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Initialize GNULIB_READ,
REPLACE_READ.
* m4/stdio_h.m4 (gl_STDIO_H): Set GNULIB_FGETC, GNULIB_FGETS,
GNULIB_FREAD, GNULIB_FSCANF, GNULIB_GETC, GNULIB_GETCHAR, GNULIB_GETS,
GNULIB_SCANF, GNULIB_VFSCANF, GNULIB_VSCANF. In non-blocking I/O is
desired and needs workarounds, set REPLACE_STDIO_READ_FUNCS.
(gl_STDIO_H_DEFAULTS): Initialize GNULIB_FGETC, GNULIB_FGETS,
GNULIB_FREAD, GNULIB_FSCANF, GNULIB_GETC, GNULIB_GETCHAR, GNULIB_GETS,
GNULIB_SCANF, GNULIB_VFSCANF, GNULIB_VSCANF, REPLACE_STDIO_READ_FUNCS.
* modules/read: New file.
* modules/nonblocking (Files): Add lib/stdio-read.c.
* modules/unistd (Makefile.am): Substitute GNULIB_READ, REPLACE_READ.
* modules/stdio (Makefile.am): Substitute GNULIB_FGETC, GNULIB_FGETS,
GNULIB_FREAD, GNULIB_FSCANF, GNULIB_GETC, GNULIB_GETCHAR, GNULIB_GETS,
GNULIB_SCANF, GNULIB_VFSCANF, GNULIB_VSCANF, REPLACE_STDIO_READ_FUNCS.
* modules/pread (Depends-on): Add read.
* modules/safe-read (Depends-on): Likewise.
* tests/test-stdio-c++.cc (fgetc, fgets, fread, fscanf, getc, getchar,
gets, scanf, vfscanf, vscanf): Verify signatures.
* doc/posix-functions/read.texi: Mention 'nonblocking' module and
problem with non-blocking pipes.
* doc/posix-functions/fgetc.texi: Likewise.
* doc/posix-functions/fgets.texi: Likewise.
* doc/posix-functions/fread.texi: Likewise.
