lib/compat.h: Undefine WORDS_BIGENDIAN when it's defined as 0

lib: Only deprecate rand/rand_r on recent enough compilers

lib: Warn if rand is used

lib: include inttypes.h to get PRIu64 & friends Including it in lib.h allows all of the Dovecot code (as well as any external plugins) to just use these macros without worrying about what system headers to include.

lib: Redefine NULL only if HAVE_TYPE_CHECKS is set

lib: Add a common HAVE_TYPE_CHECKS I'm not sure if it should be checking gcc >= 3.0 or 3.3, but they're all old so doesn't really matter. The __cplusplus check was added to both, since it wouldn't have done anything anyway as COMPILE_ERROR_IF_TRUE() is 0 for __cplusplus.

lib: Make sure NULL is defined to be ((void *)0) This avoids us having to do explicit (void *)NULL casts in e.g. io_add(..., NULL) context parameter.

global: Require comparisons to be strict boolean expressions * No implicit integer -> boolean or pointer -> boolean conversions * !expr can be used only if expr is boolean type These were checked with a patched clang. It found various actual bugs, which were fixed by the previous commits.

Removed all invocations of strtoll() and friends.

Added UNLINK_EISDIR() helper macro.

Handle "out of disk space" and "out of user quota" as separate cases. "Out of disk space" is a temporary error that should be logged as error and the failure should be sent to user as "Internal server error". Obsolete the use of MAIL_ERROR_NOSPACE and MAIL_ERRSTR_NO_SPACE. Use the clearer MAIL_ERROR_NOQUOTA and MAIL_ERRSTR_NO_QUOTA instead.

If EOVERFLOW errno isn't defined by system, fallback to ERANGE instead of EINVAL. ERANGE is used by other functions as well, such as getpwnam_r().

Compiling fix for HURD

lib-storage: Don't log errors if trying to open a mailbox with too long name. Handle ENAMETOOLONG errors the same as ENOENT.

Compile fix for HP-UX

Linux NFS: fstat() may return ENOENT instead of ESTALE in some kernel versions.

Use IO_BLOCK_SIZE macro to specify how large read/write syscalls to use. --HG-- branch : HEAD

Removed my_strptime(). It was just causing problems and wasn't used anywhere after all. --HG-- branch : HEAD

OS X: Fixed compiler warning about missing fdatasync() prototypes. --HG-- branch : HEAD

Added a wrapper for strptime() to work around issues with glibc. --HG-- branch : HEAD

compat: Renamed all my_*() fallback functions to i_my_*(). This fixes at least my_pread() conflict with libmysqlclient. --HG-- branch : HEAD

Added clock_gettime() compatibility function for systems without it. --HG-- branch : HEAD

Support systems with non-C99 vsnprintf(). --HG-- branch : HEAD

Added more fallbacks if strtoll() or strtoull() isn't implemented (e.g. HP-UX). --HG-- branch : HEAD

HP-UX: pread() and pwrite() are broken, use our own implementation. --HG-- branch : HEAD

Previous fix broke CMP_ST_CTIME() nsec checks. --HG-- branch : HEAD

Fixed compiling in BSD systems. --HG-- branch : HEAD

Replaced HAVE_ST_NSEC macro checks with more generic ST_?TIME_NSEC() macros for getting the nanosecond and ST_NTIMES_EQUAL() macro for comparing them. Added support for BSD st_?timespec fields. --HG-- branch : HEAD

Changed .h ifdef/defines to use <NAME>_H format. --HG-- branch : HEAD

Added CMP_ST_MTIME() and CMP_ST_CTIME() macros that compare also nanoseconds if they're available. --HG-- branch : HEAD

Added EDESTDIREXISTS() macro, and changed rename() calls to use it. --HG-- branch : HEAD

Handle EMLINK and EPERM errors the same way as EXDEV when handling hardlink failures. Added ECANTLINK() macro for this. --HG-- branch : HEAD

Include sys/mkdev.h with UnixWare for major() and minor() --HG-- branch : HEAD

If uoff_t type already exists, use it (UnixWare has it). --HG-- branch : HEAD

Added "bool" type and changed all ints that were used as booleans to bool. --HG-- branch : HEAD

#ifdef TRU64 -> __osf__ --HG-- branch : HEAD

Include inttypes.h with Tru64 to get uint32_t etc. types defined. --HG-- branch : HEAD

Use IOV_MAX instead of UIO_MAXIOV when available. --HG-- branch : HEAD

Added setegid() emulation for HP-UX. --HG-- branch : HEAD

If strtoull() isn't supported, fallback to strtouq(). If that's not found either, use our own implementation. --HG-- branch : HEAD

Check for libgen.h and if it's not found, use my_basename(). Also my_seteuid() didn't actually replace seteuid() before if it didn't exist. --HG-- branch : HEAD

Add seteuid() wrapper for HP-UX --HG-- branch : HEAD

importing new index code. mbox still broken. --HG-- branch : HEAD

more kludgeing to get pread/pwrite working --HG-- branch : HEAD

pread/pwrite fixes --HG-- branch : HEAD

If we don't have function foo, do it always as #define foo my_foo and create your own my_foo. Did this to pread/pwrite/madvise. --HG-- branch : HEAD

Added pwrite() compatibility --HG-- branch : HEAD

More robust error handling for mbox. --HG-- branch : HEAD

Handle EDQUOT errno as "not enough disk space" like ENOSPC. --HG-- branch : HEAD

Use separate check for uint_fast32_t. --HG-- branch : HEAD

Naming style changes, finally got tired of most of the typedefs. Also the previous enum -> macro change reverted so that we don't use the highest bit anymore, that's incompatible with old indexes so they will be rebuilt. --HG-- branch : HEAD

Marked all non-trivial buffer modifications with @UNSAFE tag. Several cleanups and a couple of minor bugfixes. --HG-- branch : HEAD

writev()'s 3rd parameter is declared as "int" pretty much everywhere, so we should do that too. --HG-- branch : HEAD

Reverted back the isdigit()/etc. They're defined to get int argument, so we shouldn't given them unsigned. --HG-- branch : HEAD

Cast chars to (unsigned int) instead of (int) in i_isdigit() etc. macros. Hopefully fixes some warnings with HP/UX. --HG-- branch : HEAD

And the missing sys/sysmacros.h include.. --HG-- branch : HEAD

Added CMP_DEV_T macro which uses major()/minor() if possible but fallbacks to direct comparing if it's not a structure. --HG-- branch : HEAD

Renamed largest_t to uintmax_t which already exists in C99. --HG-- branch : HEAD

EOVERFLOW doesn't exist everywhere, fallback it to EINVAL. --HG-- branch : HEAD

Check fdatasync() from -lrt if it's not in libc (solaris). Also fallback to fsync() entirely if fdatasync() doesn't exist. --HG-- branch : HEAD

Split IOBuffer into mmaped IBuffer, file IBuffer, memory data IBuffer and file OBuffer. --HG-- branch : HEAD

cast i_toupper() and i_tolower() return as char, so comparing highascii works without casting (breaks if comparing to unsigned char though) --HG-- branch : HEAD

added dec2str() function and largest_t type, removed itoa() and ltoa() macros and did some other cleanups. --HG-- branch : HEAD

64bit off_t fixes --HG-- branch : HEAD

Message data is parsed in blocks (no longer entirely mmap()ed). Several IOBuffer changes. All mixed signed/unsigned comparisions were fixed so code can now be compiled with gcc's -W flag. mbox support is broken currently, and there's most likely several other problems too. --HG-- branch : HEAD

Initial revision --HG-- branch : HEAD
