to the use of getpwuid when running in standalone mode. this patch allocates some persistent storage (using strdup) to store the username obtained with getpwuid in src/backend/main/main.c. this is necessary because later on, getpwuid is called again (in ValidateBinary). the man pages for getpwuid on SCO OpenServer, FreeBSD, and Darwin all have words to this effect (this is from the SCO OpenServer man page): Note ==== All information is contained in a static area, so it must be copied if it is to be saved. Otherwise, it may be overwritten on subsequent calls to these routines. in particular, on my platform, the storage used to hold the pw_name from the first call is overwritten such that it looks like an empty username. this causes a problem later on in SetSessionUserIdFromUserName. i'd assume this isn't a problem on most platforms because getpwuid is called with the same UID both times, and the same thing ends up happening to that static storage each time. however, that's not guaranteed, and is _not_ what happens on my platform (at least :). this is for the version of 7.1 available via anon cvs as of Tue Jan 23 15:14:00 2001 PST: .../src/backend/main/main.c,v 1.37 2000/12/31 18:04:35 tgl Exp -michael thornburgh, zenomt@armory.com
