* Return -1 instead of 0 upon reaching EOF. This is somewhat ill-advisedDavid Schultz2009-04-062-4/+6
| | | | | | | | | | | because it means getdelim() returns -1 for both error and EOF, and never returns 0. However, this is what the original GNU implementation does, and POSIX inherited the bug. Reported by: marcus@ Notes: svn path=/head/; revision=190773

| | | | | | | | | dprintf() is a simple wrapper around another function, so we may as well implement it. But also like getline(), we can't prototype it by default right now because it would break too many ports. Notes: svn path=/head/; revision=189356

* When f[w]printf() is called on an unbuffered file like stdout, itDavid Schultz2009-01-172-14/+23
| | | | | | | | | | | | | | | | | | | sets up a fake buffered FILE and then effectively calls itself recursively. Unfortunately, gcc doesn't know how to do tail call elimination in this case, and actually makes things worse by inlining __sbprintf(). This means that f[w]printf() to stderr was allocating about 5k of stack on 64-bit platforms, much of which was never used. I've reorganized things to eliminate the waste. In addition to saving some stack space, this improves performance in my tests by anywhere from 5% to 17% (depending on the test) when -fstack-protector is enabled. I found no statistically significant performance difference when stack protection is turned off. (The tests redirected stderr to /dev/null.) Notes: svn path=/head/; revision=187369

This will make it possible for helper routines to produce output for printf() directly, making it possible to untangle the code somewhat. In wprintf(), use the same buffering mechanism to reduce diffs to printf(). This has the side-effect of causing wprintf() to catch write errors that it previously ignored.

The compiler didn't catch these because of rampant use of the same variable to mean different things in different places. This commit should not cause any changes in functionality.

| | | | | | | | | | | | | | | | | | | | | | __sFILE. This was supposed to be done in 6.0. Some notes: - Where possible I restored the various lines to their pre-__sFILEX state. - Retire INITEXTRA() and just initialize the wchar bits (orientation and mbstate) explicitly instead. The various places that used INITEXTRA didn't need the locking fields or _up initialized. (Some places needed _up to exist and not be off the end of a NULL or garbage pointer, but they didn't require it to be initialized to a specific value.) - For now, stdio.h "knows" that pthread_t is a 'struct pthread *' to avoid namespace pollution of including all the pthread types in stdio.h. Once we remove all the inlines and make __sFILE private it can go back to using pthread_t, etc. - This does not remove any of the inlines currently and does not change any of the public ABI of 'FILE'.

* File descriptors are an int, but our stdio FILE object uses a short to holdJohn Baldwin2008-02-273-0/+39
| | | | | | | | | | | | | | | | | | | | them. Thus, any fd whose value is greater than SHRT_MAX is handled incorrectly (the short value is sign-extended when converted to an int). An unpleasant side effect is that if fopen() opens a file and gets a backing fd that is greater than SHRT_MAX, fclose() will fail and the file descriptor will be leaked. Better handle this by fixing fopen(), fdopen(), and freopen() to fail attempts to use a fd greater than SHRT_MAX with EMFILE. At some point in the future we should look at expanding the file descriptor in FILE to an int, but that is a bit complicated due to ABI issues.
