Description Andre Robatino 2011-07-26 15:01:50 UTC

Description of problem:
When redirecting the output of makedeltaiso/applydeltaiso to a file, tail -f is effective in following the progress of makedeltaiso, but not applydeltaiso, except for the initial "reading %d bytes from old iso...done" line which is immediately fflush()'d. Not a big deal, of course, but considering the heavy crunching that both programs are doing, the overhead of some extra fflush()'s shouldn't be noticeable.

Comment 1 Fedora End Of Life 2013-04-03 15:10:56 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)

Comment 2 Fedora End Of Life 2015-01-09 16:43:55 UTC

This message is a notice that Fedora 19 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 19. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 19 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

I've just taken a look at the code, but I want to see it in action.  Do you have a link to a deltaiso and the old iso for it?

Comment 5 Jonathan Dieter 2015-01-14 06:50:29 UTC

Ok, this should be fixed in deltarpm-3.6-8, which I've just built for Rawhide.  If you want me to also push it for F21 and/or F20, please re-open the bug.
