On aussie, i.e. the wiki server, I've got a script that emails me when
uploaded files have been changed. It works well on many days, but
every few days it misbehaves.
Here's the algorithm of the script:
* Check if the script has been executed within the last day, if not:
** Generate a list of files using a command similar to:
cd /home/lyx/www/pmwiki
find uploads -printf '%TY-%Tm-%Td %TH:%TM %-8s %p\n' > files
Is this the exact command? If not, what is it? Or better yet, can you
send me the script?
** 'diff' this list with a previous list of files, and email me
the difference if it is non-empty.
Normally 'files' will begin with something like:
2007-01-21 18:15 4096 uploads
2006-07-16 16:02 4096 uploads/SiteTest
2005-04-28 17:59 4096 uploads/SiteTest/ADir
2004-02-11 11:54 4 uploads/SiteTest/ADir/Aßß.txt
2007-02-06 09:21 10 uploads/SiteTest/aFile.txt
2005-05-24 12:50 4096 uploads/SiteTest/test
2003-11-22 17:29 10 uploads/SiteTest/test/aFile.txt
2005-04-28 18:01 4096 uploads/SiteTest/test/test4
2003-11-22 17:56 10 uploads/SiteTest/test/test4/aFile.txt
2005-03-31 21:35 11 uploads/SiteTest/test/test.txt
...
However, every few days it will _only_ contain the following line:
2005-05-19 22:46 28 uploads
What's going on here?
* Why only a single line, where are the rest of the files?
* Why is the date 2005-05-19 ???
This could be caused here:
if($action == 'browse' || $action == '')
if(FilesNotifyIsItTimeToUpdate())
register_shutdown_function('FilesNotifyUpdate', $pagename, getcwd());
Note the `getcwd()' that provides the second argument. Then when you get
here:
function FilesNotifyUpdate($pagename, $dir='') {
global $FilesNotify;
$curdir = getcwd();
if($dir) { flush(); chdir($dir); }
You'll be chdir'ing to whatever getcwd() returned before, and that must
depend upon what browse action is underway. So you're NOT chdir'ing to
/home/lyx/www/pmwiki all the time. To see where you are going, check the
date on /home/lyx/www/pmwiki/test/wiki/uploads/.
Here's a different idea: Why not just do this as a bash script and
install it as a cron job? Then you don't have to access this script on
every browsing action. Something along these lines (yes, it's ugly with
all the error checking included):
!#/bin/bash
WORKDIR=wiki.d;
if ! cd /home/lyx/www/pmwiki/; then echo $0 failed to chdir...!; exit
1; fi
if ! [ -d $WORKDIR ]; then if ! mkdir $WORKDIR; then echo $0 failed to
mkdir...!; exit 1; fi
if [ -e $WORKDIR/files ]; then
if ! cp $WORKDIR/files $WORKDIR/files.0; then echo $0 failed to
cp...!; exit 1; fi;
else
if [ ! -e $WORKDIR/files.0 ]; then
if ! touch $WORKDIR/files.0; then echo $0 failed to touch...!;
exit 1; fi
fi
fi
find uploads -printf '%TY-%Tm-%Td %TH:%TM %-8s %p\n' > $WORKDIR/files
diff $WORKDIR/files $WORKDIR/files.0
And of course cron will send you the output if it's your cron job.

I'm stumped, any ideas?

PS. I might be able to "fix" the script by checking if 'files'
contains a single line, and then try to repeat the 'find' command. Not
a pretty solution though...
PPS.
The list of files are stored in:
/home/lyx/www/pmwiki/wiki.d/files
in case anyone wants to look.
The actual script is in
/home/lyx/www/pmwiki/farm.d/cookbook/filesNotify.php
