Subject: Time::Format makes endless loop on forking
Download (untitled) / with headers
text/plain 1.9k
If you use Time::Format in any of your modules, your program gets non-forkable. Unless any other module I know, Time::Format opens itself as filedescriptor. You can see it in lsof: # lsof -p 4246 .... perl 4246 root 8r REG 0,13 31092 25419 /usr/share/perl5/Time/Format.pm (/dev/root) ... # If you then fork and run a funktion of Time::Format the fork ends in a endless loop, as you can see in strace: read(8, "", 4096) = 0 fstat(8, {st_mode=S_IFREG|0644, st_size=31092, ...}) = 0 read(8, "", 4096) = 0 fstat(8, {st_mode=S_IFREG|0644, st_size=31092, ...}) = 0 read(8, "", 4096) = 0 fstat(8, {st_mode=S_IFREG|0644, st_size=31092, ...}) = 0 read(8, "", 4096) = 0 fstat(8, {st_mode=S_IFREG|0644, st_size=31092, ...}) = 0 read(8, "", 4096) = 0 fstat(8, {st_mode=S_IFREG|0644, st_size=31092, ...}) = 0 read(8, "", 4096) = 0 fstat(8, {st_mode=S_IFREG|0644, st_size=31092, ...}) = 0 read(8, "", 4096) = 0 fstat(8, {st_mode=S_IFREG|0644, st_size=31092, ...}) = 0 read(8, "", 4096) = 0 fstat(8, {st_mode=S_IFREG|0644, st_size=31092, ...}) = 0 read(8, "", 4096) = 0 fstat(8, {st_mode=S_IFREG|0644, st_size=31092, ...}) = 0 read(8, "", 4096) = 0 fstat(8, {st_mode=S_IFREG|0644, st_size=31092, ...}) = 0 read(8, "", 4096) = 0 fstat(8, {st_mode=S_IFREG|0644, st_size=31092, ...}) = 0 read(8, "", 4096) = 0 fstat(8, {st_mode=S_IFREG|0644, st_size=31092, ...}) = 0 read(8, "", 4096) = 0 fstat(8, {st_mode=S_IFREG|0644, st_size=31092, ...}) = 0 read(8, "", 4096) = 0 fstat(8, {st_mode=S_IFREG|0644, st_size=31092, ...}) = 0 read(8, "", 4096) = 0 Please don't open files unless you programm it to be fork safe!
