Broken -stay_open

[rnicz]

I'm using exiftool.exe on Windows 8 running it with Ruby script using IO.popen() - Ruby's pipe. Here is code snippet:


      cmd = [exiftool, '-charset', 'cp1250', '-charset', 'IPTC=cp1250', '-stay_open', 'True', '-@', '-']
      [...cut...]
      # mode have to be wt+: binary mode sets external encoding to ASCII-8BIT
      @exifio=IO.popen(cmd, "wt+:cp1250")
      @exifio.sync = true


Next @exifio variable can be used to communicate with running exiftool instance to manipulate images.

Up to previous version (9.54) everything worked fine, but when I upgraded exiftool to version 9.55 exiftool exits immediately with error code -1.

Command line call

exiftool.exe -charset cp1250 -charset IPTC=cp1250 -stay_open True -@ exchangefile

works as expected - so exiftool.exe works fine and can be controlled by writing to exchangefile.

Now I have no time to investigate further, I'm only signal problems I encountred.

I suggest uninstalling then re-installing.  My guess is that your installation is corrupt.

Than you for your answer.

In fact I did not remove temporary folder before installing new version of exiftool.exe. Tomorrow I will try this step and send you a message.

I wonder if name of temporary folder can be modified with version number of exiftool.exe or something...

The temporary folder does contain a version number already.  The problem is likely that there was an error expanding the new version.  Under normal circumstances you do not need to remove the temporary folder when upgrading.

It was antivirus problem.

I'm using Comodo Antivirus. New exiftool.exe was not recognized by Comodo Antivirus, with state "Needs to
be submited". In this state I couldn't mark it as recognized: it was always restored as untrusted.
I submited it to Comodo, next I updated it's database and problems gone.

It was first time I had such problem with Exiftool.

Thank you for assistance.

I'm glad you figured this out.  Antivirus problems I have seen in the past didn't look like this, so I wouldn't have suspected this source for the problem.
