** Description changed: [Impact] Programs previously using nanosleep syscall and with glibc 31's update being switched to use clock_nanosleep broke due to clock_nanosleep using CLOCK_REALTIME returns EINVAL in wsl1. [Test Case] Run sleep in WSL1 on Windows 10 2004 or older version. The fixed version works correctly, the not fixed version breaks in Focal. + Run the following program under strace and observe that the fallback is + applied only when it is needed: + + #include <time.h> + #include <stdio.h> + + int main (int argc, char ** argv) { + struct timespec ts, rem; + clock_gettime(CLOCK_REALTIME, &ts); + printf("Sleep 1.5s with TIMER_ABSTIME\n"); + ts.tv_nsec += 500000000L; + if (ts.tv_nsec > 1000000000L) { + ts.tv_nsec -= 1000000000L; + ts.tv_sec += 1; + } + ts.tv_sec += 1; + clock_nanosleep(CLOCK_REALTIME, TIMER_ABSTIME, &ts, &rem); + + printf("sleep 1.2s\n"); + ts.tv_sec = 1; + ts.tv_nsec = 200000000L; + clock_nanosleep(CLOCK_REALTIME, 0, &ts, &rem); + + printf("sleep 1.2s with CLOCK_MONOTONIC\n"); + ts.tv_sec = 1; + ts.tv_nsec = 200000000L; + clock_nanosleep(CLOCK_MONOTONIC, 0, &ts, &rem); + + printf("invalid sleep -1s (+200ms)\n"); + ts.tv_nsec = 200000000L; + ts.tv_sec = -1; + clock_nanosleep(CLOCK_REALTIME, 0, &ts, &rem); + + printf("invalid sleep 1s (-200ms)\n"); + ts.tv_nsec = -200000000L; + ts.tv_sec = 1; + clock_nanosleep(CLOCK_REALTIME, 0, &ts, &rem); + + printf("invalid sleep 0s (+1.200ms as nsec)\n"); + ts.tv_nsec = 1200000000L; + ts.tv_sec = 1; + clock_nanosleep(CLOCK_REALTIME, 0, &ts, &rem); + + } + [Regression Potential] The fix is falling back to using monotonic time ... FIXME - [Original Bug Text] Right now I am trying Ubuntu 20.04 on WSL and I noticed that when I run htop in WSL 1st generation, it is completely blank: https://user-images.githubusercontent.com/15316889/78563857-31697b00 -784e-11ea-9f21-338a6cf8cb23.gif The previous version (htop 2.1.0) works without any issue. I am using htop 2.2.0-2build1 on Ubuntu 20.04 on WSL1 on Windows 10 build 19592.1001.
