2014-04-21Initial draft xattr supportPeter Seebach1-1/+1
Initial, incomplete, support for extended attributes. Extended attributes are implemented fairly naively, using a second table in the file database using the primary file table's id as a foreign key. The ON DELETE CASCADE behavior requires sqlite 3.6.19 or later with foreign key and trigger support compiled in. To reduce round-trips, the client does not check for existing attributes, but rather, sends three distinct set messages; OP_SET_XATTR, OP_CREATE_XATTR, OP_REPLACE_XATTR. A SET message always succeeds, a CREATE fails if the attribute already exists, and a REPLACE fails if the attribute does not already exist. The /* flags */ feature of makewrappers is used to correct path names appropriately, so all functions are already working with complete paths, and can always use functions that work on links; if they were supposed to dereference, the path fixup code got that. The xattr support is enabled, for now, conditional on whether getfattr --help succeeds. Not yet implemented: Translation for system.posix_acl_access, which is used by "cp -a" (or "cp --preserve-all") on some systems to try to copy modes.

2010-04-26Updates/improvements for loggingPeter Seebach1-1/+1
Send program name (program_invocation_name from glibc) along with the tag. Along the way, restructure the fds/pids/tags arrays to be an array of client structures in pseudo_server, and add the message type to the set of things logged -- logging that a message was a ping is more useful than appending the text "ping" to it. Add support for type and program to pseudolog. Add deletion to pseudolog. Handle usage message formatting when there's an odd number of known specifiers for pseudolog.
