Guillem Jover f41fdcf1 2013-10-21T05:07:56 Add funopen() function This is a wrapper over the glibc fopencookie() function. We diverge from the FreeBSD, OpenBSD and DragonFlyBSD declarations, because seekfn() there wrongly uses fpos_t, assuming it's an integral type, and any code using that on a system where fpos_t is a struct (such as GNU-based systems or NetBSD) will fail to build. In which case, as the code has to be modified anyway, we might just as well use the correct declaration.
Guillem Jover ee04e8de 2013-10-10T09:49:04 build: Set subdir-objects automake option Bump automake minimal version to 1.9.

Guillem Jover c5b95902 2013-07-11T12:25:54 Move setproctitle() automatic initialization to its own library The automatic initialization cannot be part of the main shared library, because there is no thread-safe way to change the environ global variable. This is not a problem if the initializaion happens just at program load time, but becomes one if the shared library is directly or indirectly dlopen()ed during the execution of the program, which could have either kept references to the old environ or could change it in some other thread. This has been observed for example on systems using Samba NSS modules. To avoid any other possible fallout, the constructor is split into a new static library that needs to be linked explicitly into programs using setproctitle(). As an additional safety measure the pkg-config linker flags will mark the program as not allowing to be dlopen()ed so that we avoid the problem described above.

Guillem Jover 3077d2ff 2013-07-12T22:15:58 build: Move version ABI from Makefile to configure.ac It's easier to find there, and the value can be reused in case we have to provide another shared library.
Guillem Jover 6faea4d2 2013-05-29T02:23:56 Force setproctitle() into .init_array section The GNU .init_array support is an extension over the standard System V ABI .init_array support, which passes the main() arguments to the init function. This support comes in three parts. First the dynamic linker (from glibc) needs to support it. Then function pointers need to be placed in the section, for example by using __attribute__((constructor)), that the compiler (gcc or clang for example) might place in section .ctors and the linker (from binutils) will move to .init_array on the output object, or by placing them directly into .init_array by the compiler when compiling. If this does not happen and the function pointers end up in .ctors, then they will not get passed the main() arguments, which we do really need in this case. But this relies on recent binutils or gcc having native .init_array support, and not having it disabled through --disable-initfini-array. To guarantee we get the correct behaviour, let's just place the function pointer in the .init_array section directly, so we only require a recent enough glibc.

Guillem Jover 06f0585c 2013-05-21T10:31:59 build: Compress the distribution tarball with xz instead of gzip
Guillem Jover e9933255 2013-05-25T17:11:53 Make setproctitle() available in 0.2 and 0.5 version nodes Make the 0.5 version the default, so that code wanting the actual implemented version can get a proper versioned depdendency. For code linked against the old version, make it available as an alias.
Guillem Jover 35785f8d 2012-11-25T21:10:53 Modify setproctitle() to conform to project coding style Use local getprogname()/setprogname() instead of reimplementing them locally. Use clearenv() if available, not just on glibc. Use bool instead of _Bool. Use paranthesis on sizeof. Fold the SPT_MIN macro into spt_min(). Make spt_init() static. Avoid unnecessary gotos.
Guillem Jover 14524b54 2012-06-03T07:39:42 build: Set default compiler variables from configure This centralizes the setting so there's no duplication anymore, makes sure the user supplied variables are never overridden, and are only set when using gcc.

Guillem Jover 943939d0 2011-12-31T08:39:44 Add new closefrom() function Code taken from sudo, man page from FreeBSD.

Guillem Jover b5cc17d6 2011-07-05T23:27:31 Use getexecname() if available for getprogname() This function is present on Solaris.
