* don't assert on bad args, instead return an error..jmg2013-10-073-1/+604
| | | | | | | | | | | | | | | Since so many programs don't check return value, always NUL terminate the buf... fix rounding when using base 1024 (the bug that started it all)... add a set of test cases so we can make sure that things don't break in the future... Thanks to Clifton Royston for testing and the test program... Approved by: re (hrs, glebius) MFC after: 1 week
* libc/stdio: Allow fopen/freopen modes in any order (except initial r/w/a).jilles2013-09-062-0/+123
| | | | | | | | | | Austin Group issue #411 requires 'e' to be accepted before and after 'x', and encourages accepting the characters in any order, except the initial 'r', 'w' or 'a'. Given that glibc accepts the characters after r/w/a in any order and that diagnosing this problem may be hard, change our libc to behave that way as well.

* Add libiconv based versions of *c16*() and *c32*().ed2013-06-032-0/+75
| | | | | | | | | | | | | I initially thought wchar_t was locale independent, but this seems to be only the case on Linux. This means that we cannot depend on the *wc*() routines to implement *c16*() and *c32*(). Instead, use the Citrus libiconv that is part of libc. I'll see if there is anything I can do to make the existing functions somewhat useful in case the system is built without libiconv in the nearby future. If not, I'll simply remove the broken implementations. Reviewed by: jilles, gabor

| | | | | | | | because different tests have different ideas about what it means to be "close enough" to the right answer, depending on the properties of the function being tested.

The regression tests did their job: they failed, someone brought it up on the mailing lists, and then the issue got ignored for 6 months. Oops. There may still be some regressions for functions we don't have test coverage for yet.

* Add <uchar.h>.ed2013-05-213-1/+268
| | | | | | | | | | | | The <uchar.h> header, part of C11, adds a small number of utility functions for 16/32-bit "universal" characters, which may or may not be UTF-16/32. As our wchar_t is already ISO 10646, simply add light-weight wrappers around wcrtomb() and mbrtowc(). While there, also add (non-yet-standard) _l functions, similar to the ones we already have for the other locale-dependent functions. Reviewed by: theraven
* popen(): Add 'e' mode character to set close-on-exec on the new fd.jilles2013-05-201-4/+4
| | | | | | | | | | | | | | If 'e' is used, the kernel must support the recently added pipe2() system call. The use of pipe2() with O_CLOEXEC also fixes race conditions between concurrent popen() calls from different threads, even if the close-on-exec flag on the fd of the returned FILE is later cleared (because popen() closes all file descriptors from earlier popen() calls in the child process). Therefore, this approach should be used in all cases when pipe2() can be assumed present. The old version of popen() rejects "re" and "we" but treats "r+e" like "r+".

* wordexp(): Remove wrong IFS usage.jilles2013-04-011-0/+19
| | | | | | | | | | | Words in shell script are separated by spaces or tabs independent of the value of IFS. The value of IFS is only relevant for the result of substitutions. Therefore, there should be a space between 'wordexp' and the words to be expanded, not an IFS character. Paranoia might dictate that the shell ignore IFS from the environment (even though our sh currently uses it), so do not depend on it in the new test case.

Conversely, use NULL as write-callback when opened in read-only mode. - Implement the handling of the ``b'' character in the mode argument. A binary buffer differs from a text buffer (default mode if ``b'' is omitted) in that NULL bytes are never appended to writes and that the "buffer data length" equals to the size of the buffer. - Remove shall from the man page. Use indicative instead. Also, specify that the ``b'' flag does not conform with POSIX but is supported by glibc. - Update the regression test so that the ``b'' functionality and the "buffer data length" concepts are tested. - Minor style(9) corrections.
