| | | | | | | | | | | | | | | | FBSDprivate locale symbols. These functions are needed by libcompat. Add _cleanup to the list of stdio FBSDprivate symbols. Some third party applications use this. This will be removed and replaced by fcloseall() once libc version is bumped. Add _res to the list of resolv symbols. Found by: portbuilder runs (thanks Kris!) Notes: svn path=/head/; revision=157282

* Make the %V{is} extension handle a NULL pointer like %s does: output "(null)"Poul-Henning Kamp2006-01-255-1/+187
| | | | | | | | | | | | | | | | Add %M{essage} extension which prints an errno value as the corresponding string if possible or numerically otherwise. It is not currently possible to do the syslog(3) like %m extension because errno would need to get capatured on entry to the first function in the printf family, so %M requires you to supply errno as an argument. Add %Q{uote} extension which will print a string in double quotes with appropriate back-slash escapes (only) if necessary. Notes: svn path=/head/; revision=154815

* Add an extensible version of our *printf(3) implementation to libcPoul-Henning Kamp2005-12-169-0/+2054
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* With current pthread implementations, a mutex initialization willDavid Xu2005-12-163-9/+19
| | | | | | | | | | | | | | | allocate a memory block. sscanf calls __svfscanf which in turn calls fread, fread triggers mutex initialization but the mutex is not destroyed in sscanf, this leads to memory leak. To avoid the memory leak and performance issue, we create a none MT-safe version of fread: __fread, and instead let __svfscanf call __fread.

* /* You're not supposed to hit this problem */Poul-Henning Kamp2005-12-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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@ Notes: svn path=/head/; revision=153375
