Hi,
Currently ‘primitive-load’ opens files without O_CLOEXEC:
port = scm_open_file_with_encoding (filename,
scm_from_latin1_string ("r"),
SCM_BOOL_T, /* guess_encoding */
scm_from_latin1_string ("UTF-8"));
We should fix that; here’s an example where it shows:
--8<---------------cut here---------------start------------->8---
$ guix shell bash -- sh -c 'ls -l /proc/$$/fd'
total 0
lrwx------ 1 ludo users 64 Sep 3 21:20 0 -> /dev/pts/0
lrwx------ 1 ludo users 64 Sep 3 21:20 1 -> /dev/pts/0
lrwx------ 1 ludo users 64 Sep 3 21:20 2 -> /dev/pts/0
lr-x------ 1 ludo users 64 Sep 3 21:20 3 -> /proc/9563/fd
lr-x------ 1 ludo users 64 Sep 3 21:20 5 ->
/gnu/store/4qbqaa4dgr2fwjjs9i2naqrd0djrcnw3-guix-command
$ head -1 $(type -P guix)
#!/gnu/store/9z95jms1r801z1kxpiq5xw594cxaw5jx-guile-wrapper/bin/guile
--no-auto-compile
--8<---------------cut here---------------end--------------->8---
For a proper fix, one possibility would be to first augment
‘scm_i_mode_to_open_flags’ to recognize some letter for O_CLOEXEC. In
glibc, fopen(3) uses “e” for that.
Thoughts?
