11 * A general description of the supergroup changes
14 * In AFS users can be members of groups. When you add
15 * a user, u1, to a group, g1, you add the user id for u1
16 * to an entries list in g1. This is a list of all the
18 * You also add the id for g1 to an entries list in u1.
19 * This is a list of all the groups this user is a
21 * The list has room for 10 entries. If more are required,
22 * a continuation record is created.
24 * With UMICH mods, u1 can be a group. When u1 is a group
25 * a new field is required to list the groups this group
26 * is a member of (since the entries field is used to
27 * list it's members). This new field is supergroups and
28 * has two entries. If more are required, a continuation
30 * There are two additional fields required, nextsg is
31 * an address of the next continuation record for this
32 * group, and countsg is the count for the number of
33 * groups this group is a member of.
37 * 09/18/95 jjm Add mdw's changes to afs-3.3a Changes:
38 * (1) Add the parameter -groupdepth or -depth to
39 * define the maximum search depth for supergroups.
40 * Define the variable depthsg to be the value of
41 * the parameter. The default value is set to 5.
43 * (3) Make sure the sizes of the struct prentry and
44 * struct prentryg are equal. If they aren't equal
45 * the pt database will be corrupted.
46 * The error is reported with an fprintf statement,
47 * but this doesn't print when ptserver is started by
48 * bos, so all you see is an error message in the
49 * /usr/afs/logs/BosLog file. If you start the
50 * ptserver without bos the fprintf will print
52 * The program will terminate with a PT_EXIT(1).
55 * Transarc does not currently use opcodes past 520, but
56 * they *could* decide at any time to use more opcodes.
57 * If they did, then one part of our local mods,
58 * ListSupergroups, would break. I've therefore
59 * renumbered it to 530, and put logic in to enable the
60 * old opcode to work (for now).
62 * 2/1/98 jjm Add mdw's changes for bit mapping for supergroups
64 * Before fetching a supergroup, this version of ptserver
65 * checks to see if it was marked "found" and "not a
66 * member". If and only if so, it doesn't fetch the group.
67 * Since this should be the case with most groups, this
68 * should save a significant amount of CPU in redundant
69 * fetches of the same group. After fetching the group,
70 * it sets "found", and either sets or clears "not a
71 * member", depending on if the group was a member of
72 * other groups. When it writes group entries to the
73 * database, it clears the "found" flag.

78 * A general description of the supergroup changes
81 * In AFS users can be members of groups. When you add a user, u1,
82 * to a group, g1, you add the user id for u1 to an entries list
83 * in g1. This is a list of all the members of g1. You also add
84 * the id for g1 to an entries list in u1. This is a list of all
85 * the groups this user is a member of. The list has room for 10
86 * entries. If more are required, a continuation record is created.
88 * With UMICH mods, u1 can be a group. When u1 is a group a new
89 * field is required to list the groups this group is a member of
90 * (since the entries field is used to list it's members). This
91 * new field is supergroups and has two entries. If more are
92 * required, a continuation record is formed.
94 * There are two additional fields required, nextsg is an address
95 * of the next continuation record for this group, and countsg is
96 * the count for the number of groups this group is a member of.
98 * Bit mapping support for supergroups:
100 * Before fetching a supergroup, this version of ptserver checks to
101 * see if it was marked "found" and "not a member". If and only if
102 * so, it doesn't fetch the group. Since this should be the case
103 * with most groups, this should save a significant amount of CPU in
104 * redundant fetches of the same group. After fetching the group, it
105 * sets "found", and either sets or clears "not a member", depending
106 * on if the group was a member of other groups. When it writes
107 * group entries to the database, it clears the "found" flag.
