Hello:
I'm hoping to save some time during deployments by comparing a local zip
file against a remote server's zip file. My first thought was to use the
checksum task, but the timestamps are deffinately going to be different.
The basic idea is this:
Perform a local build and zip up the files.
Compare the local zip file against a remote zip file
If it's different then push the new zip file and extract on the remote
machine.
If it's not different, don't do anything.
I tried this with the checksum task originally. I would generate a file
that gets pushed to the remote machine at the same time I push the zip file
if things were different. Then I can just grab the checksum file from the
remote machine and compare it against whats newly built/zipped.
In theory the byte size could be the same (a boolean gets changed from 0 to
1 in a prop file for example).
So is this hopeless? I'm looking at saving 2-3hrs over the course of a day
if I can somehow detect that there were indeed changes.
My other thought was to parse the VSS history to see if there are any files
that have changed -- but again -- that seems slower then just a compare of
the files.
Needless to say, simply comparing the date (OutOfDate task or UpToDate task)
won't work since the zip file will be newly made and the same file on the
remote machine might be several days/weeks old. My other challenge is that
I only have SSH and FTP access to the remote machine...
If someone else has run into this or if anyone else has some tips that I'm
just overlooking I would greatly appreciate it!!
In advance, many thanks!!!
Brent
