elfutils code names

elfutils code names

[Mark Wielaard]

Hi,

On irc (#elfutils on libera.chat) we had a discussion about the
elfutils code names. For some reason those are only in the irc channel
topic. Which seems to mean not many people know about them. I could
recover the following:

0.170 "DWARF4 1/2"
0.171 "DWARF5 split!"
0.172 "DWARF5 bugs split!"
0.173 "crash free"
0.174 "extended shnum"
0.176 "At your own RISC-V"
0.177 "What is your category, class and taxonomy?"
0.178 "All the build-id you can count!" 
0.179 "All your packages are belong to us!"
0.180 "We got an L, we got an T, can we have a O?"
0.181 "Show me your ARMs"
0.182 "October Surprise!"
0.183 "100+ commits"
0.184 "negative results"
0.185 "oops, I did it again"       
0.186 "Just In Time"
0.187 "no zero negatives"
0.188 "no section left behind"

I believe some older versions also had code names, but I could not find
them.

Cheers,

Mark

Found some more:

0.162 "hard hat" 
0.163 "size matters" 
0.164 "strip, no unstrip!" 
0.165 "big DWARF & tiny ELF" 
0.166 "bugs be gone!" 
0.167 "disassemble this!" 
0.168 "kthxbye" 

So 0.169 is missing and I am not sure any version before 0.162 had a
code name. But if you remember differently please update/correct this
list.

Thanks,

Mark

A nice archeological work Mark! Please set that in stone somewhere, ideally
in the elfutils git repository ;)
