Description Mark Goodwin 2010-06-16 11:54:15 UTC 
Created attachment 424419 [details]
iostat patch to remove extraneous newline for long device names

Description of problem:
iostat prints an extra unwanted newline for device names that exceed 13 chars

Version-Release number of selected component (if applicable):
all RHEL4 and RHEL5 versions of the sysstat package. This is
fixed upstream, simple patch attached.

How reproducible: always, just need long device names

Steps to Reproduce:
1. set up a long device name, e.g. a lengthy dm-multipath alias
2. run iostat
  
Actual results: extraneous newline after the device name

Expected results: no extraneous newline

Additional info:
upstream has removed this newline since sysstat-7.0.3,
see http://pagesperso-orange.fr/sebastien.godard/

There shouldn't be any issue affecting existing scripts that expect
to parse this newline (they should be tolerant of it not being present).
Comment 5 Branislav Náter 2011-05-27 12:11:13 UTC 
Bugfix was successfully verified on sysstat-7.0.2-8.el5 package on all supported architectures.

No new line is printed after device with long name.
