Typedef Documentation

◆ TLimitsPrintHandler

typedef void(* TLimitsPrintHandler) (ELimitsExitCode, size_t, CTime &, TLimitsPrintParameter)

Type of handler for printing a dump information after generating any limitation event.

Attention: If you use handlers together with SetCpuLimit(), be aware! See SetCpuLimit() for details.; The exit print handler can be registered only once at first call to SetCpuTimeLimit() or SetMemoryLimit(), even if you don't specify handler directly and passed it as NULL. Be aware. All subsequent attempts to set new handler will be ignored, but limits will be changed anyway.

◆ GetVirtualMemoryLimitHard()

size_t GetVirtualMemoryLimitHard ( void )

[UNIX only] Get "hard" memory limit of the virtual memory (address space) in bytes for a current process.

Returns: Returns "hard" value set by setrlimit(), SetMemoryLimit() or ulimit command line utility for virtual memory address space. 0 - if an error occurs and CNcbiError is set, or the memory limit is set to "unlimited".

Note: The implementation of malloc() can be different on many flavors of UNIX, and we usually don't know how exactly it is implemented on the current system. Some systems use sbrk()-based implementation (heap), other use mmap() system call and virtual memory (address space) to allocate memory, some other use hybrid approach and may allocate memory in two different ways depending on requested memory size and certain parameters. Almost all modern Unix versions uses mmap()-based approach for all memory allocations or at least for big chunks of memory, so probably virtual memory limits is more important nowadays.

advise	Advise on expected memory usage pattern.

Returns

◆ SetCpuTimeLimit()

bool SetCpuTimeLimit	(	unsigned int	max_cpu_time,
		unsigned int	terminate_delay_time,
		TLimitsPrintHandler	handler = `NULL`,
		TLimitsPrintParameter	parameter = `NULL`
	)

[UNIX only] Set CPU time usage limit.

Set the limit for the CPU time that can be consumed by current process.

Parameters

max_cpu_time	The maximal amount of seconds of CPU time can be consumed by the process. The 0 value lifts off the CPU time restrictions if allowed to do so. For multi-threaded applications this can be a sum of time for all threads (OS dependent).
terminate_delay_time	The time in seconds that the process will have to terminate itself after receiving a signal about exceeding CPU usage limit. After that it can be killed by OS.
handler	Pointer to a print handler used for dump output in the case of reaching CPU usage limit. Use default handler if passed as NULL. Note, that default handler is not async-safe (see attention below), and can lead to coredump and application crash instead of program termination, so use it on your own risk.
parameter	Parameter carried into the print handler. Can be passed as NULL.

Returns: Completion status.

Note: Setting a low CPU time limit cannot be generally undone to a value higher than "max_cpu_time + terminate_delay_time" at a later time.

Attention: The exit print handler can be registered only once at first call to SetCpuTimeLimit() or SetMemoryLimit(), even if you don't specify handler directly and passed it as NULL! Be aware. All subsequent attempts to set new handler will be ignored, but limits will be changed anyway.; Only async-safe library functions and system calls can be used in the print handler. For example, you cannot use C++ streams (cout/cerr) and printf() calls here, but write() is allowed... You can find a list of such functions in the C++ documentation (see man, Internet and etc). Also, avoid to alter any shared (global) variables, except that are declared to be of storage class and type "volatile sig_atomic_t".

◆ SetMemoryLimit()

bool SetMemoryLimit	(	size_t	max_size,
		TLimitsPrintHandler	handler = `NULL`,
		TLimitsPrintParameter	parameter = `NULL`
	)

[UNIX only] Set memory limit.

Set the limit for the size of used memory allocated by the process.

Parameters

max_size	The maximal amount of memory in bytes that can be allocated by the process. Use the same limits for process's data segment (including heap) and virtual memory (address space). On 32-bit systems limit is at most 2 GiB, or this resource is unlimited. The 0 value lift off the heap restrictions. This value cannot exceed current hard limit set for the process.
handler	Pointer to a print handler used for dump output in the case of reaching memory limit. Use default handler if passed as NULL.
parameter	Parameter carried into the print handler. Can be passed as NULL. Useful if singular handler is used for setting some limits. See also SetCpuTimeLimit().

Returns: Completion status. It returns TRUE if both, the memory limits for the data segment and virtual memory, limitations were set. It can return FALSE if the limits for the data segment has changed, but setting new values for the virtual memory fails.

Note: By default it sets soft and hard memory limits to the same value.; Setting a limits may not work on some systems, depends on OS, compilation options and etc. Some systems enforce memory limits, other didn't. Also, only privileged process can set hard memory limit.; If the memory limit is reached, any subsequent memory allocations fails.

Attention: The exit print handler can be registered only once at first call to SetCpuTimeLimit() or SetMemoryLimit(), even if you don't specify handler directly and passed it as NULL. Be aware. All subsequent attempts to set new handler will be ignored, but limits will be changed anyway.; if you use std::set_new_handler(), it should be called after SetMemoryLimit(). It override any memory related print handler set previously.

◆ SetMemoryLimitHard()

bool SetMemoryLimitHard	(	size_t	max_size,
		TLimitsPrintHandler	handler = `NULL`,
		TLimitsPrintParameter	parameter = `NULL`
	)

[UNIX only] Set hard memory limit.

Note: The hard limit acts as a ceiling for the soft limit: Current soft memory limit will be automatically decreased, if it exceed new value for the hard memory limit.; Only privileged process can increase current hard level limit.

◆ SetMemoryLimitSoft()

bool SetMemoryLimitSoft	(	size_t	max_size,
		TLimitsPrintHandler	handler = `NULL`,
		TLimitsPrintParameter	parameter = `NULL`
	)

[UNIX only] Set soft memory limit.

Note: The soft limit is the value that the kernel enforces for the corresponding resource. An unprivileged process may only set its soft limit to a value in the range from 0 up to the hard limit, and (irreversibly) lower its hard limit. A privileged process may make arbitrary changes to either limit value.
