Log Message:
* Here's metadata monitoring. Details are in the manual and in libefsd's
header file.
* I'm using getpwuid() now instead of using $HOME to find a user's home
directory.
* The metadata access convenience calls in libefsd now behave as the manual
says, i.e. they do not duplicate memory. Keep this in mind when you want
to keep the data you receive around.
* Updated doco accordingly.
* Fixlets I cannot remember right now :)

Added Files:
efsd_meta_monitor.c efsd_meta_monitor.h
Log Message:
* Here's metadata monitoring. Details are in the manual and in libefsd's
header file.
* I'm using getpwuid() now instead of using $HOME to find a user's home
directory.
* The metadata access convenience calls in libefsd now behave as the manual
says, i.e. they do not duplicate memory. Keep this in mind when you want
to keep the data you receive around.
* Updated doco accordingly.
* Fixlets I cannot remember right now :)

Author : cpk
Project : e17
Module : apps/efsd
Dir : e17/apps/efsd/doc
Modified Files:
efsd-manual.sgml manual.raw
Log Message:
* Here's metadata monitoring. Details are in the manual and in libefsd's
header file.
* I'm using getpwuid() now instead of using $HOME to find a user's home
directory.
* The metadata access convenience calls in libefsd now behave as the manual
says, i.e. they do not duplicate memory. Keep this in mind when you want
to keep the data you receive around.
* Updated doco accordingly.
* Fixlets I cannot remember right now :)

+ In some occasions it's useful to know when a file's metadata changes. Therefore,

+
+ The functions responsible for metadata monitoring are simple to use, there is
+ <link linkend="API-efsd-start-monitor-metadata"><function>efsd_start_monitor_metadata</function></link>
+ to start monitoring a metadata entry, and
+ <link linkend="API-efsd-stop-monitor-metadata"><function>efsd_stop_monitor_metadata</function></link>
+ to stop the monitoring. You can monitor metadata entries that do not exist yet.
+ If a metadata item that is monitored gets changed by a a client, all clients

Author : cpk
Project : e17
Module : apps/efsd
Dir : e17/apps/efsd/efsd
Modified Files:
efsd_commands.c efsd_event_queue.c efsd_event_queue.h
efsd_fs.c efsd_globals.h efsd_main.c efsd_main.h
efsd_meta_monitor.c efsd_monitor.c efsd_statcache.c
Log Message:
* proper handling of EOF returned from recvmsg() when a client shut down.
Keeps Efsd from eating 100& cpu in some cases.
* fixes when copying symlinks. Also a readlink() fix for efsd_readlink().
* removed the array of the client fds from the global variables, instead
using efsd_main_get_fd() now, and updated calls accordingly. Much nicer
in case I need to go move to poll() to make things more robust.

libefsd.c
Log Message:
Mhmmm okay. I noticed that when I moved some stuff around in libefsd a
while ago, I accidentally disabled monitoring of single files. That's
fixed now.
But I see very inconsistent behavior when monitoring single files with fam,
both in Efsd and other test apps. Basically, sometimes I just get the
file-exists event for the file, but no change events afterwards. If I
stop the monitor, stop the fam client (again no matter whether it's efsd or
not) and restart it, it usually works. I'll need to check if this is fixed
in the newer fam releases, I'm still on fam 2.6.4.

Log Message:
AAAAAAAAHHH new code :)
* Fixed reporting of dead links -- a dangling symlink is
correctly reported as dead-link/unknown-fs again. Seems I broke
that a while ago.
* Prefixed the inclusion path for the libxml2 headers with
"libxml" to fix the issues reported by Alan.
* Fixed a race condition in the filetype move-to-front heuristic:
under high load it was possible that a matching magic description
got moved to the front of the list while other checks where iterating
over the list already, the matching filetype was thus not found.
* efsd_misc_get_user_dir() also uses getpwuid to find out the home dir.
* Moved the socket file to /tmp to avoid issues with nfs-mounted
homes, as Raster had pointed out.
* Added an event callback interface to libefsd to be able to register
handlers instead of having to use switch-case statements. Added
management code to libefsd to make these handlers per-monitor.
This is completely untested yet and will probably blow up right
into your face :)
* Fixed a bug in efsdsh, -ls actually performs an lstat() now.

Tag: SPLIT
TODO
Log Message:
AAAAAAAAHHH new code :)
* Fixed reporting of dead links -- a dangling symlink is
correctly reported as dead-link/unknown-fs again. Seems I broke
that a while ago.
* Prefixed the inclusion path for the libxml2 headers with
"libxml" to fix the issues reported by Alan.
* Fixed a race condition in the filetype move-to-front heuristic:
under high load it was possible that a matching magic description
got moved to the front of the list while other checks where iterating
over the list already, the matching filetype was thus not found.
* efsd_misc_get_user_dir() also uses getpwuid to find out the home dir.
* Moved the socket file to /tmp to avoid issues with nfs-mounted
homes, as Raster had pointed out.
* Added an event callback interface to libefsd to be able to register
handlers instead of having to use switch-case statements. Added
management code to libefsd to make these handlers per-monitor.
This is completely untested yet and will probably blow up right
into your face :)
* Fixed a bug in efsdsh, -ls actually performs an lstat() now.
