Hi all, I did a test about run a bash scriplt never quit,but met a memory usage issue that cause used memory continuous increase. This issue was present in bash-3.2.x, bash-4.0.x, bash-4.1.x, bash-4.2.x, bash-4.3.x. However, This issue was disappeared in bash-4.4.0, I can't trace which patch fixed the issue or which new feature was introduced in bash-4.4.0.
Here is bash script: ------------------------------------------------------------------------------ #!/bin/bash logger "Started testing" while(true);do while (true); do ls > /dev/null done done ------------------------------------------------------------------------------- root@localhost:/root> cat /proc/767/smaps |grep -A10 heap 01ba5000-01be8000 rw-p 00000000 00:00 0 [heap] Size: 268 kB Rss: 152 kB Pss: 152 kB Shared_Clean: 0 kB Shared_Dirty: 0 kB Private_Clean: 0 kB Private_Dirty: 152 kB Referenced: 152 kB Swap: 0 kB KernelPageSize: 4 kB ---------------------------------------------------------------------------------- root@localhost:/root> cat /proc/767/smaps |grep -A10 heap 00d4c000-00e55000 rw-p 00000000 00:00 0 [heap] Size: 1060 kB Rss: 1048 kB Pss: 1048 kB Shared_Clean: 0 kB Shared_Dirty: 0 kB Private_Clean: 0 kB Private_Dirty: 1048 kB Referenced: 1048 kB Swap: 0 kB KernelPageSize: 4 kB ---------------------------------------------------------------------------------- Could someone help to tell me which part of changes in bash-4.4.0, that would be give me a direction backport code changes from bash-4.4 to bash-3.2.x and bash-4.3.x.
