From: Ludovic Courtès <ludovic.courtes <at> inria.fr> To: bug-guix <at> gnu.org Subject: ‘update-cached-checkout’ (Guile-Git/libgit2) can sometimes get stuck forever Date: Fri, 28 Jun 2024 12:30:55 +0200
‘update-cached-checkout’ can sometimes get stuck on a connection forever. This is problematic for ‘cuirass register’, as it means that it’ll silently stay forever in an unfinished ‘remote-fetch’, thus without updating repos anymore: --8<---------------cut here---------------start------------->8--- (gdb) info threads Id Target Id Frame * 1 Thread 0x7f3996c1a380 (LWP 13322) "guile" 0x00007f3996d20626 in epoll_wait () from /gnu/store/ln6hxqjvz6m9gdd9s97pivlqck7hzs99-glibc-2.35/lib/libc.so.6 [...] 29 Thread 0x7f3975000640 (LWP 31125) "git-checkout" 0x00007f3996d21cf6 in recv () from /gnu/store/ln6hxqjvz6m9gdd9s97pivlqck7hzs99-glibc-2.35/lib/libc.so.6 (gdb) thread 29 [Switching to thread 29 (Thread 0x7f3975000640 (LWP 31125))] #0 0x00007f3996d21cf6 in recv () from /gnu/store/ln6hxqjvz6m9gdd9s97pivlqck7hzs99-glibc-2.35/lib/libc.so.6 (gdb) bt #0 0x00007f3996d21cf6 in recv () from /gnu/store/ln6hxqjvz6m9gdd9s97pivlqck7hzs99-glibc-2.35/lib/libc.so.6 #1 0x00007f398c17ba7b in ??
