Description John Sullivan 2013-05-28 09:36:15 EDT
Description of problem:

A recent "yum update" threw the same dep conflict on two separate machines with very different life histories. The conflict itself was easy enough to fix, but what this is about is the apparently new "load-transaction" feature:

# yum update
Downloading Packages:
Running Transaction Check
ERROR with transaction check vs depsolve:
Your transaction was saved, rerun it with:
 yum load-transaction /tmp/yum_save_tx.2013-05-28.13-19.vw37ZA.yumtx

# fix dependency problem

# yum load-transaction /tmp/yum_save_tx.2013-05-28.13-19.vw37ZA.yumtx
Loaded plugins: auto-update-debuginfo, fastestmirror, presto, priorities, refresh-packagekit
Error: rpmdb ver mismatched saved transaction version, aborting.

Doing an "rm -f /var/lib/rpm/__db* ; rpm --rebuilddb", either before the "yum load-transaction", or before the "yum update" that writes the transaction file itself, doesn't appear to fix this problem. Just re-running the "yum update" did work, but this saved transaction feature doesn't.

(Note: none of these packages were part of the failing update transaction. The installed versions were stable throughout.)

How reproducible:

Apparently always, assuming you can trigger a transaction failure by some other means.

Steps to Reproduce:
1. Run a failing "yum update"
2. Fix the underlying problem.
3. Obey yum's direction to restart with "yum load-transaction"

Actual results:

A transaction that has only just been saved fails to load with an rpmdb version mismatch error.

Expected results:

Yum should create save files that can actually be loaded. If there is some reason why that can't be done, then it should not create them in the first place, and should not tell you to do something which won't work.
Comment 1 John Sullivan 2013-05-28 10:29:08 EDT
# head -1 /tmp/yum_save_tx.2013-05-28.13-19.vw37ZA.yumtx

That string comes from ...site_packages/yum/__init__.py, via save_ts/load_ts:

$ python
Python 2.7.3 (default, Aug  9 2012, 17:23:57) 
[GCC 4.7.1 20120720 (Red Hat 4.7.1-5)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import yum
>>> i = yum.YumBase()
>>> j = i.rpmdb.simpleVersion(main_only=True)
Loaded plugins: auto-update-debuginfo, fastestmirror, presto, priorities,
              : refresh-packagekit
>>> print j
['4780:39e2d558f43a947cec2004d8a706d492358a51d8', {}]

load_ts requires that the current value of simpleVersion[0] matches the value retrieved when save_ts was called.

What is that hash value and when does it change? On any rpm operation? If so, it seems that fixing a dep problem (usually by removing conflicting packages, as in this case) must *guarantee* that the load check will fail, which doesn't sound too useful.
Comment 2 Fedora End Of Life 2013-12-21 08:46:03 EST
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. 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 '18'.

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 18's end of life.

Thank you for reporting this issue and we are sorry that we may not be 
able to fix it before Fedora 18 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 to Fedora 18's end of life.

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.
Comment 3 Fedora End Of Life 2014-02-05 16:34:45 EST
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
