#86024 — Bug#1098512: linux-perf: `perf report` shows `Cannot load tips.txt file, please install perf!`

Package: linux-perf
Version: 6.12.15-1
Severity: normal


Dear Debian folks,


With

     $ LANG= dpkg -l linux-perf
     […]
     ii  linux-perf     6.12.15-1    amd64        Performance analysis 
tools for Linux

recording a profile and trying to show it

     $ sudo perf record -a -g -F 999
     ^C[ perf record: Woken up 42 times to write data ]
     [ perf record: Captured and wrote 11,877 MB perf.data (59158 samples) ]

     $ sudo chown pmenzel: perf.data
     $ perf report perf.data

the profile is loaded, but nothing is displayed, and only the header is 
shown, and at the bottom the message below is written:

     perf report` shows Cannot load tips.txt file, please install perf!

The file is shipped by `linux-perf`, but it’s compressed:

     $ dpkg -S /usr/share/doc/linux-perf/tips.txt.gz
     linux-perf: /usr/share/doc/linux-perf/tips.txt.gz

Uncompressing the file, the message is not shown anymore. Still nothing 
is shown, but that is for another bug report.


Kind regards,

Paul

The problem with compressed tips.txt is reported at #1088747 so
merging the two bugs.

About not showing something, right: according to perf report -h:

    -i, --input <file>    input file name

Please try perf report -i perf.data. See as well perf-report(1).

(or with no arguments at all to perf report in the directory where you
have your perf.data).

Regards,
Salvatore
