alloc.c --- allocation of all resources which might have to be reclaimed
eventually, including memory, files, and child processes.
- =================================================
- List of various #defines used in the code:
- The Apache code, specifically in conf.h, uses a variety of #defines to
- control how the code is compiled and what options are available for each
- supported OS. The following list provides a short list and description
- of these #defines.
-
- --
-
- NEED_*:
- If the particular OS doesn't supply the specified function, we use the
- Apache-supplied version (in util.c).
-
- NEED_STRERROR:
- NEED_STRDUP:
- NEED_STRCASECMP:
- NEED_STRNCASECMP:
- NEED_INITGROUPS:
- NEED_WAITPID:
- NEED_STRERROR:
- --
-
- HAVE_*:
- Does this OS have/support this capability?
-
- HAVE_GMTOFF:
- Define if the OS's tm struct has the tm_gmtoff element
-
- HAVE_RESOURCE:
- Define if the OS supports the getrlimit()/setrlimit() functions
-
- HAVE_MMAP:
- Define if the OS supports the BSD mmap() call. This is used by various
- OSs to allow the scoreboard file to be held in shared mmapped-memory
- instead of a real file.
-
- HAVE_SHMGET:
- Define if the OS has the SysV-based shmget() family of shared-memory
- functions. Used to allow the scoreboard to live in a shared-memory
- slot instead of a real file.
-
- HAVE_CRYPT_H:
- Define if the OS has the <crypt.h> header file.
-
- HAVE_SYS_SELECT_H:
- Define if the OS has the <sys/select.h> header file.
-
- HAVE_SYS_RESOURCE_H:
- Define if the OS has and supports the getrlimit/setrlimit
- family. Apache uses this to determine if RLIMIT_CPU|VMEM|DATA|RLIMIT
- is found and used.
- --
-
- USE_*:
- These #defines are used for functions and ability that aren't exactly
- required but should be used.
-
- USE_FCNTL_SERIALIZED_ACCEPT:
- Define if the OS requires a mutex "lock" around the socket accept()
- call. Use fcntl() locking.
-
- USE_FLOCK_SERIALIZED_ACCEPT:
- Define if the OS requires a mutex "lock" around the socket accept()
- call. Use flock() locking (fcntl() is expensive on some OSs, esp.
- when using NFS).
-
- USE_LONGJMP:
- use the longjmp() call instead of siglongjmp()
-
- --
-
- NO_*:
- These are defined if the OS does NOT have the specified function or if
- we should not use it.
-
- NO_KILLPG:
- NO_SETSID:
- NO_USE_SIGACTION:
- Do not use the sigaction() call, even if we have it.
- NO_LINGCLOSE:
- Do not use Apache's soft, "lingering" close feature to
- terminate connections.
- --
-
- MISC #DEFINES:
- Various other #defines used in the code.
-
- JMP_BUF:
- The variable-type for siglongjmp() or longjmp() call.
-
- MOVEBREAK:
- Amount to move sbrk() breakpoint, if required, before attaching
- shared-memory segment.
