svnlook cat -t $TXN $REPO broken ?

[Phil Pinkerton <pc...@gmail.com>]

Seems that trying to create a pre-commit hook script that limits the size of
a file to be committed is not an easy task.

svnlook has been recommended but I have yet to see it work properly the "-t"
option does not seem to find the transaction.

svnlook cat -t $TXN $REPO   always returns an error

# Check file size. do not allow Access files greater than 1MB.
    REPOS=$1
    TXN=$2
    SVNLOOK=/svn/bin/svnlook

    # get a list of all the files changed
    $SVNLOOK changed -t "$TXN" "$REPOS" | while read type file
    do
        # skip all the files unless they end in .mdb
        [ ${file##*.} != "mdb" ] && continue   #Skip unless a .mdb suffix
        # I cat out the file and then count the characters.
        # If it is greater than 1mb, I put it in my error array.
        # Is there a better way to get the size of a file w/ svnlook?
                       if [ $($SVNLOOK cat -t "$TXN"  "$REPOS" $file | wc
-c) -ge "1000000" ]
error here ??     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        then
           $error["$file"]=""$file: We can't commit Access databases larger
than 1mb"
        fi
    done

I do almost exactly that, with


if $SVNLOOK changed -t "$TXN" "$REPOS" | grep --quiet /Jamfile ; then
    echo found jamfile >&2
    JAMPATH=$($SVNLOOK changed -t "$TXN" "$REPOS"  | cut -c5- | egrep
'Jamfile$')
     $SVNLOOK cat "$REPOS" -t "$TXN" "$JAMPATH" > $tmpdir/Jamfile

(leaving out the tmpdir bits and the rest - we actually have a
(product-specific) "jamlint" script we check out at the same time, and
if it fails, the commit fails...)  So the obvious question is *what*
error are you getting?  You didn't say in your post...
