guix: inferior: Fix the behaviour of open-inferior #:error-port.

2022-07-08T12:51:34+00:00

I'm looking at this as the Guix Data Service uses this behaviour to record and
display logs from inferior processes.

* guix/inferior.scm (open-bidirectional-pipe): Call dup2 for file descriptor
2, passing either the file number for the current error port, or a file
descriptor for /dev/null.
* tests/inferior.scm ("#:error-port stderr", "#:error-port pipe"): Add two new
tests that cover some of the #:error-port behaviour.

inferior: Close duplicate socketpair file descriptor.

2022-05-20T16:46:07+00:00

* guix/inferior.scm (open-bidirectional-pipe): Pass SOCK_CLOEXEC to
'socketpair'.
* tests/inferior.scm ("close-inferior"): Add test.

inferior: Support querying package replacements.

2021-05-15T11:14:47+00:00

I'm looking at this to help with adding support for looking up package
replacements to store in the Guix Data Service.

* guix/inferior.scm (inferior-package-replacement): New procedure.
* tests/inferior.scm ("inferior-package-replacement"): New test.

inferior: Make sure test refers to guile@3.0.

2021-04-28T23:22:04+00:00

* tests/inferior.scm ("inferior-package-inputs"): Compare with
GUILE-3.0-LATEST since that's what 'lookup-inferior-packages' returns.

repl: Fix exception handling for interpreted code.

2021-01-20T23:14:38+00:00

The 'stack' variable could be #f when code is interpreted, which in
practice happens when running in "legacy" mode--i.e., when
'open-inferior' invokes "guile" instead of "guix repl".

* guix/repl.scm (send-repl-response)[handle-exception]: Check whether
STACK is true before passing it to 'stack->frames'.
* tests/inferior.scm ("&inferior-exception, legacy mode"): New test.

inferior: Add 'inferior-eval-with-store' tests.

2021-01-20T23:14:38+00:00

* tests/inferior.scm ("inferior-eval-with-store, exception")
("inferior-eval-with-store, not a procedure"): New tests.

Merge branch 'master' into core-updates

2020-03-21T21:16:02+00:00

inferior: '&inferior-exception' includes a stack trace.

2020-03-19T14:14:08+00:00

* guix/inferior.scm (port->inferior): Bump protocol to (0 1 1).
(&inferior-exception)[stack]: New field.
(read-repl-response): Recognize 'exception' form for protocol (0 1 1).
* tests/inferior.scm ("&inferior-exception"): Check the value returned
by 'inferior-exception-stack'.

tests: Fix up reference to 'guile-2.2'.

2020-03-17T14:46:15+00:00

This is a followup to b6bee63bed4f013064c0d902e7c8b83ed7514ade.

* tests/inferior.scm ("inferior-package-search-paths"): Refer to
'guile-3.0' instead of 'guile-2.2'.

inferior: Distinguish inferior exceptions.

2020-03-12T10:52:38+00:00

This avoids ambiguities when looking at a backtrace where the exception
was actually thrown by an inferior in a very different context.

* guix/inferior.scm (&inferior-exception): New condition type.
(read-repl-response): Add optional 'inferior' parameter.  Raise
'&inferior-exception' instead of rethrowing to KEY when receiving an
'exception' message.
(read-inferior-response): Pass INFERIOR to 'read-repl-response'.
* tests/inferior.scm ("&inferior-exception"): New test.
