When I attempt to emerge po4a, the ebuild goes into a CPU-bound loop. It also appears to leak memory at 1 meg every 30-40 seconds. In fact, I let it run for about 10 hours or so last weekend, and it almost consumed the entire machine: 4 gigs of RAM and 64 gigs of swap.

X Translate binary manpages to it It may be worth noting, that primarily English systems may *NOT* want translations of documentation to foreign languages on their system -- and so the dependency of dpkg on app-text/po4a may be undesirable (and there should be a patch that allows it to be bypassed). It would also be nice if there were a gentoo option that allowed the removal of all foreign language files except a limited subset (for me: US-en, fr & ru). E.g. "LINGUAS=en" or "LINGUAS="en fr ru" in make.conf. The foreign language files for a robust system installation take up a large amount of space on /usr.
I have the same symptoms, occurring at the same point - where it starts to "X Translate binary manpages to ca". If you Google that string, the first hit (a patch, so it might be suspect...) shows it's iterating over a generated series of languages. I thought it might be a problem with my locale settings - I'm using LC_ALL='en_GB.UTF-8'. I did have LANG="", but I changed it to the same as LC_ALL, and it still loops. I also had LINGUAS="en_GB uk" (noob mistake - I don't speak Ukrainian...) but it still loops when I set it to LINGUAS="en_GB". I second Robert Bradbury's comment that there should no need to translate to ca, fr, etc; it would be "nice" if the ebuild were sensitive to LINGUAS, though that may be too major surgery for the benefit it brings. All I want is for "alien" to work!
Created attachment 141489 [details] Workaround to delete language files during "emerge po4a" Well, I finally got past this but its a real kludge. As mentioned by others the problem is in perl hanging on the processing of the language files (which should not even be done for "english" systems). The basic strategy is to delete all of the language files (it, pl, ca, fr, es) which the po4a-translate perl script hangs on. The trick is to do it after the package is unpacked but before the files cause the emerge to hang. Tricky, but I managed to put together a script to do it. Now the only problem is that while /usr/bin/po4a is produced, it appears to be buggy as it hangs the subsequent dpkg emerge (to be discussed later). The attached script should be fairly self-explanatory. The problem may be with the use of perl5.8.8. One strategy might be to back off on the installed version of perl and see if one can get around the problem. The other approach might be to compare older versions of po4a with the one produced after using my workaround script and see what got changed which may be causing the problem.
Now, for solving the "dpkg" emerge. (If the dpkg emerge failure is filed under additional bugs someone should point them here). As it turns out "dpkg" contains on the order of 100+ ".po" (language) files which modify the man pages and perhaps other files when emerging dpkg. These files seem to rely on /usr/bin/po4a, which suffers from the same perl "hanging" problem found when emerging "po4a". Solutions tried: 1) Killing all of the hung perl processes (~24?) does not work because while the killing works ok, a higher level part of the build detects that some of the processes were killed. 2) Removing all of the *.cfg files during the build doesn't work (the build still calls perl and it doesn't seem to detect that the command files are missing). 3) Removing all of the *.po files during the build doesn't seem to work either. What does seem to work is replacing /usr/bin/po4a with a fake po4a which always works, e.g. #!/usr/bin/perl5.8.8 # Dummy po4a -- replace in /usr/bin before emerging dpkg exit 0; # always work... One does end up with a new set of dpkg-* files in /usr/bin and the English dpkg man pages appear to be updated. Not sure about what happens to the foreign dpkg man pages. Simple tests of dpkg seem to indicate it is working but more extensive testing should be applied. Somebody really needs to investigate what is wrong with po4a and/or perl5.8.8 to resolve the po4a/dpkg problem without such kludgy solutions.
Same infinite loop for me, ~amd64. It's been happening for some time, and I usually remember to edit the proposed update list from my weekly updates, but sometimes I forget ...
Please test if po4a-0.33.3 fixes this problem for you. Reopen if it isn't fixed.
Bug has been refiled as bug # 219889.
