Commit that introduced the performance degradation is effab4a
(fix: workaround for undocumented caching in getpw/getgr funcs)
Rewrote caching at the getpwent/getpwnam/getgrent/getgrnam level,
which restores performance pre-effab4a and even enhances it in somes cases,
for example on a 2000-accounts and 2000-groups bastion, we are:
- 11% faster on --osh help
- 35% faster on --osh selfListAccesses (reduces syscalls by 87%)
The commands selfListAccesses, accountListAccesses,
groupList, groupListServers, groupListGuestAccesses and
accountList now have options to filter their output through
pattern matching, with --include and --exclude.
The output from the commands using print_acls() is also more
human-friendly, with auto-adjusting column length, and empty
columns omitted.
Closes#60.
