2024-10-16support: Make support_process_state_wait return the found stateAdhemerval Zanella1-2/+4
So caller can check which state was found if multiple ones are asked. Checked on x86_64-linux-gnu. Reviewed-by: Florian Weimer <fweimer@redhat.com>

2022-03-23support: Fix support_process_state_wait path size calculationAdhemerval Zanella1-1/+2
Use INT_STRLEN_BOUND to proper get the maximum pid_t size. Also fix the wrong calculation (the 3 should multiply the sizeof (pid_t)). Checked on x86_64-linux-gnu.

I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines

2020-12-28support: Make support_process_state_wait wait lessSamuel Thibault1-1/+1
Tests such as posix/tst-waitid.c make heavy use of support_process_state_wait, and thus on non-Linux where it falls back to sleeping, a 2s sleep makes such test time out, while 1s remains fine enough.
2020-04-03support: Change xgetline to return 0 on EOFFlorian Weimer1-1/+1
The advantage is that the buffer will always contain the number of characters as returned from the function, which allows one to use a sequence like /* No more audit module output. */ line_length = xgetline (&buffer, &buffer_length, fp); TEST_COMPARE_BLOB ("", 0, buffer, line_length); to check for an expected EOF, while also reporting any unexpected extra data encountered.

2020-02-27support: Add support_process_state_waitAdhemerval Zanella1-0/+92
It allows parent process to wait for child state using a polling strategy over procfs on Linux. The polling is used over ptrace to avoid the need to handle signals on the target pid and to handle some system specific limitation (such as YAMA). The polling has some limitations, such as resource consumption due the procfs read in a loop and the lack of synchronization after the state is obtained. The interface idea is to simplify some sleep synchronization waitid tests and is to reduce timeouts by replacing arbitrary waits.
