__vprintf(): switch from strerror() to strerror_rl() This eliminates the use of non-thread-safe function in printf*() family, and make the call locale-aware. Also, it stops obliterating the strerror() static buffer, which aligns with the POSIX requirement that implementations must behave as if no standard-mandated functions call strerror().

The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Make stdio deferred cancel-safe. If used with fopen(3)/fdopen(3)-ed FILEs, stdio accurately uses non-cancellable internal versions of the functions, i.e. it seems to be fine with regard to cancellation. But if the funopen(3) and f{r,w}open(3) functions were used to open the FILE, and corresponding user functions create cancellation points (they typically have no other choice), then stdio code at least leaks FILE' lock. The change installs cleanup handler which unlocks FILE. Some minimal restructuring of the code was required to make it use common return place to satisfy hand-rolled pthread_cleanup_pop() requirements.

If the size passed to {,v}s{w,n}printf is larger than INT_MAX+1 (i.e., the return value would overflow), set errno to EOVERFLOW and return an error. This improves the chances that buggy applications -- for instance, ones that pass in a negative integer as the size due to a bogus calculation -- will fail in safe ways. Returning an error in these situations is specified by POSIX, but POSIX appears to have an off-by-one error that isn't duplicated in this change. Previously, some of these functions would silently cap the size at INT_MAX+1, and others would exit with an error after writing more than INT_MAX characters. PR: 39256 MFC after: 2 weeks

When f[w]printf() is called on an unbuffered file like stdout, it 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.)

Convert the insidious macros that handle printf()'s buffering into slightly less evil inline functions, and move the buffering state into a struct. 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.

Next stage of stdio cleanup: Retire __sFILEX and merge the fields back into __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'.

Add an extensible version of our *printf(3) implementation to libc on probationary terms: it may go away again if it transpires it is a bad idea. This extensible printf version will only be used if either environment variable USE_XPRINTF is defined or one of the extension functions are called. or the global variable __use_xprintf is set greater than zero. In all other cases our traditional printf implementation will be used. The extensible version is slower than the default printf, mostly because less opportunity for combining I/O operation exists when faced with extensions. The default printf on the other hand is a bad case of spaghetti code. The extension API has a GLIBC compatible part and a FreeBSD version of same. The FreeBSD version exists because the GLIBC version may run afoul of our FILE * locking in multithreaded programs and it even further eliminate the opportunities for combining I/O operations. Include three demo extensions which can be enabled if desired: time (%T), hexdump (%H) and strvis (%V). %T can format time_t (%T), struct timeval (%lT) and struct timespec (%llT) in one of two human readable duration formats: "%.3llT" -> "20349.245" "%#.3llT" -> "5h39m9.245" %H will hexdump a sequence of bytes and takes a pointer and a length argument. The width specifies number of bytes per line. "%4H" -> "65 72 20 65" "%+4H" -> "0000 65 72 20 65" "%#4H" -> "65 72 20 65 |er e|" "%+#4H" -> "0000 65 72 20 65 |er e|" %V will dump a string in strvis format. "%V" -> "Hello\tWor\377ld" (C-style) "%0V" -> "Hello\011Wor\377ld" (octal) "%+V" -> "Hello%09Wor%FFld" (http-style) Tests, comments, bugreports etc are most welcome.

/* You're not supposed to hit this problem */ For some denormalized long double values, a bug in __hldtoa() (called from *printf()'s %A format) results in a base 16 digit being rounded up from 0xf to 0x10. When this digit is subsequently converted to string format, an index of 10 reaches past the end of the uppper-case hex/char array, picking up whatever the code segment happen to contain at that address. This mostly seem to be some character from the upper half of the byte range. When using the %a format instead of %A, the first character past the end of the lowercase hex/char table happens to be index 0 in the uppercase hex/char table hextable and therefore the string representation features a '0', which is supposedly correct. This leads me to belive that the proper fix _may_ be as simple as masking all but the lower four bits off after incrementing a hex-digit in libc/gdtoa/_hdtoa.c:roundup(). I worry however that the upper bit in 0x10 indicates a carry not carried. Until das@ or bde@ finds time to visit this issue, extend the hexdigit arrays with a 17th index containing '?' so that we get a invalid but consistent and printable output in both %a and %A formats whenever this bug strikes. This unmasks the bug in the %a format therefore solving the real issue may both become easier and more urgent. Possibly related to: PR 85080 With help by: bde@

Respect locale while handling of \' flag. In original version grouping was hardcoded. It assumed that thousands separator should be inserted to separate each 3 numbers. I.e. grouping string "\003" was assumed for all cases. In correct case (per POSIX) vfprintf should respect locale defined non-monetary (LC_NUMERIC category) grouping sequence. Also simplify thousands_sep handling.

Implement several of the c99 updates to printf(3): - New length modifiers: hh, j, t, z. - New flag: '. Note that %'f is not yet implemented. - Use "inf"/"nan" for efg formats, "INF"/"NAN" for EFG formats. - Implemented %q in terms of %ll; if "quad_t" is not "long long" %q will break. Still to do: - %C, %S, %lc, %ls (wide character support) - %'f (thousands in integer portion of %f) - %a/%A (exact hex representation of floating-point numbers) Garrett Wollman wrote the first version of the vfprintf.c update; Mike Barcroft wrote the first version of the printf.3 changes.

Remove _THREAD_SAFE and make libc thread-safe by default by adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of <errno.h> from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch

Replace memory leaking instances of realloc with non-leaking reallocf. In some cases replace if (a == null) a = malloc(x); else a = realloc(a, x); with simple reallocf(a, x). Per ANSI-C, this is guaranteed to be the same thing. I've been running these on my system here w/o ill effects for some time. However, the CTM-express is at part 6 of 34 for the CAM changes, so I've not been able to do a build world with the CAM in the tree with these changes. Shouldn't impact anything, but...

Don't assign the va_list variable 'ap' directly to the argtable because va_list is not a pointer on alpha. Instead, use the va_arg() macro to return the address that is stored in the argtable.

Add FILE locking stubs for libc. Change the FILE locking to support kernel threads when linked with libpthread (which you haven't see yet). This requires that libc become thread-safe and thread-aware, testing __isthreaded before attempting to do lock/unlock calls. The impact on non-threaded programs is minor. This change works with libc_r, so it's the best compromise.

Suggested by: Bruce Evans, Jeffrey Hsu, Gary Palmer Added $Id$'s to files that were lacking them (gpalmer), made some cosmetic changes to conform to style guidelines (bde) and checked against NetBSD and Lite2 to remove unnecessary divergences (hsu, bde) One last code cleanup:- Removed spurious casts in fseek.c and stdio.c. Added missing function argument in fwalk.c. Added missing header include in flags.c and rget.c. Put in casts where int's were being passed as size_t's. Put in missing prototypes for static functions. Changed second args of __sflags() inflags.c and writehook() in vasprintf.c from char * to const char * to conform to prototypes. This directory now compiles with no warnings with -Wall under gcc-2.6.3 and with considerably less warnings than before with the ultra-pedantic script I used for testing. (Most of the remaining ones are due to const poisoning).

The 4.4-lite vfprintf counted the %# hex prefix and the sign in the precision; ANSI X3J11 is not crystal clear but certainly says that the precision specifies the number of /digits/, and signs and "0x" aren't really digits. NetBSD already has a similar patch.

The 4.4lite version is similar to revision 1.3 in old-cvs and is missing all of jtc's fixes in revision 1.4 in old-cvs. Revision 1.2 in ncvs fixed one of the old bugs but introduced at least one new one (for %.0e). old-cvs log: revision 1.4 date: 1993/11/04 19:38:22; author: jtc; state: Exp; lines: +33 -20 My work from NetBSD to make printf() & friends ANSI C compliant.
