Method of updating

[NewsArchive]

Has anyone used SetupBuilder to make an updating program that simply looks
for noncurrent files by comparing isntalled and current CRC information?

Patching is a neat idea but impractical as many updates are created.

Sending all files to a client always works but is always a big download.

I'd list like to make a list of CRC numbers for our "current" files, compate
those with the CRC of the isntalled files and simply download and install
the non-current files.

Yes, SetupBuilder's own (web) update process uses this method. It compares
the CRC32 and only downloads and installs/updates what is required.

Great to hear.

Any sample scripts?

I presume you have an automated process that creates a text file on the
server with all of the CRC numbers for your files?

No, there is no external text file involved. "File Replacement Option" in
the File Properties dialog is set to "Check File (CRC)" and the SetupBuilder
installer does the dirty work.

The same method is used when our full SetupBuilder install image goes into
"maintenance mode" (see attached screenshot) to update an existing
SetupBuilder 6 installation.

Friedrich,

Can you use the CRC creation capability in Clarion:

MODULE('C60RUNX.LIB')
CRC32(*STRING buffer,ULONG buffersize,ULONG
seed),ULONG,RAW,NAME('Cla$crc32')
END


to create the CRC and have that CRC compatible with the SetupBuilder
generated CRC ?

Yes, SetupBuilder supports the standard CRC-32 method.

Please note that you also have a CRC-32 function available in the script
with "Get File Info (File CRC-32)".
