Iain Patterson	620fc9f569	Fixed broken environment on restart. ... We were calling duplicate_environment() to copy the service's initial environment prior to restarting it. However the duplicate_environment() function modified its input by replacing = characters with NULLs. That is not allowed; the memory returned by GetEnvironmentStrings() must be treated as readonly. After two restarts the application would run with a null environment and probably crash. We now copy the initial environment on to the heap and operate on the copy, ensuring that the corruption does not occur. Thanks Alessandro Gherardi.	11 years ago
Iain Patterson	5380a4a53d	Renamed un/format_environment(). ... The format_environment() and unformat_environment() functions could be used to format any double null-terminated string list, and are not specificially tied to formatting environment blocks.	11 years ago
Iain Patterson	2e3a41e1d5	Added more environment functions. ... useful_environment() skips the uninteresting variables at the start of an environment block, returning a pointer to the first useful variable. expand_environment_string() expands a string with ExpandEnvironmentStrings() and returns a pointer to the expanded string, which must be freed after use. set_environment_block() iterates through all the variables in an environment block, expands each one with expand_environment_string() and calls SetEnvironmentVariable() with the expanded value. clear_environment() removes all variables from the current environment. duplicate_environment() duplicates an environment block by first calling clear_environment() then set_environment_block() with the source block. Thus it ensures that the variables in the block - and only those - are set in the current environment.	11 years ago
