Bug 488331

Hmm, can't reproduce here (failtest is a dummy test package trying to install a file in /boot and /boot filled up all the way):

[root@turre ~]# rpm -U /home/pmatilai/rpmbuild/RPMS/failtest-1.0-1.noarch.rpm	installing package failtest-1.0-1.noarch needs 5MB on the /boot filesystem
[root@turre ~]# rpm -U --test /home/pmatilai/rpmbuild/RPMS/failtest-1.0-1.noarch.rpm
	installing package failtest-1.0-1.noarch needs 5MB on the /boot filesystem
[root@turre ~]# yum -d0 -y --nogpgcheck install /home/pmatilai/rpmbuild/RPMS/failtest-1.0-1.noarch.rpm


Transaction Check Error:
  installing package failtest-1.0-1.noarch needs 5MB on the /boot filesystem

Error Summary
-------------
Disk Requirements:
  At least 5MB needed on the /boot filesystem.

okay. so I can't figure out how I was making this happen, now, either.

I've tested it with multiple pkgs on multiple fses to no avail.

I'm closing notabug. sorry for the noise.

okay. I can duplicate it.

This is on F10 with rpm-4.6.0-1.fc10.i386

http://sethdot.org/~skvidal/misc/transtest-no-disk-check.txt

It performs and completes the transaction test but only reports the diskspace errors when it goes to run the transaction.

there's a lot of data in this report:

on line 1841 - you see the Transaction Test completes
and right below that you see the errors come out from attempting to Run the transaction.

I'd say the disk-space check does run on the test-transaction too, the difference comes from actual disk-space difference between the two runs: the test-transaction can create rpmdb indexes and such which take some amount of disk-space which can cause this situation if the margin is small enough.

This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '10'.

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 prior to Fedora 10's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 10 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 please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

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.

The process we are following is described here:

There's no way to make this bulletproof as long as the rest of the system is alive around rpm, system logs get written to, yum itself is logging on the same fs between test and actual transaction and users can create files in /var/tmp/ etc. Rpm should however at least try to account for estimated database size, which is not done at all currently (tracked upstream at http://rpm.org/ticket/26)
