Subject: [PATCH] rktio: patch rktio_process for "/bin/sh" on Guix
|
|
|
|
Racket provides the functions `system` and `process`,
|
|
which execute shell commands using `sh` (or `cmd` on Windows).
|
|
Racket assumes that `sh` can be found at "/bin/sh",
|
|
which is not necessarily true on Guix.
|
|
|
|
This patch adds a special case for "/bin/sh" to `rktio_process`,
|
|
the C function that implements the core of `system`, `process`,
|
|
and related Racket functions.
|
|
|
|
If:
|
|
|
|
1. The nonstandard but ubiquitous macro `_PATH_BSHELL` from
|
|
<paths.h> is defined; and
|
|
|
|
2. `rktio_process` is called with the exact path "/bin/sh"; and
|
|
|
|
3. The file specified by `_PATH_BSHELL` exists;
|
|
|
|
then `rktio_process` will execute the file specified by `_PATH_BSHELL`
|
|
instead of "/bin/sh".
|
|
|
|
Checking that the path specified by `_PATH_BSHELL` exists safeguards
|
|
against obscure errors if attempting to use stand-alone executables
|
|
built by the patched Racket in non-Guix envoronments.
