Function Documentation

◆ apply_pull_filter()

bool apply_pull_filter	(	const struct options *	o,
		char *	line
	)

Filter an option line by all pull filters.

If a match is found, the line is modified depending on the filter type, and returns true. If the filter type is reject, SIGUSR1 is triggered and the return value is false. In that case the caller must end the push processing.

◆ atoi_constrained()

bool atoi_constrained	(	const char *	str,
		int *	value,
		const char *	name,
		int	min,
		int	max,
		int	msglevel
	)

Converts a str to an integer if the string can be represented as an integer number and is between min and max.

The integer is stored in value. On error, print a warning with msglevel using name. value is not changed on error.

Returns: true if the integer has been parsed and stored in value, false otherwise

◆ atoi_warn()

int atoi_warn	(	const char *	str,
		int	msglevel
	)

Converts a str to an integer if the string can be represented as an integer number.

Otherwise print a warning with msglevel and return 0

◆ check_push_update_option_flags()

bool check_push_update_option_flags	(	char *	line,
		int *	i,
		unsigned int *	flags
	)

Checks the formatting and validity of options inside push-update messages.

This function is used to validate and process options in push-update messages. It performs the following checks:

Determines if the options are updatable.
Checks for the presence of the - flag, which indicates that the option should be removed.
Checks for the ? flag, which marks the option as optional and suppresses errors if the client cannot update it.
Increase the value pointed by 'i' when we encounter the ‘’-'and'?'flags after validating them and updating the appropriate flags in theflagsvariable. --?option,-option,?optionare valid formats,?-optionis not a valid format.
If the flags and the option are not consecutive, the option is invalid: - ?option,-? option,- option` are invalid formats.

Parameters

line	A pointer to an option string. This string is the option being validated.
i	A pointer to an integer that represents the current index in the `line` string.
flags	A pointer where flags will be stored: `PUSH_OPT_TO_REMOVE`: Set if the `-` flag is present. `PUSH_OPT_OPTIONAL`: Set if the `?` flag is present.
