* assembler: Separate 'process-relocs' from 'patch-relocs!'.Ludovic Courtès2023-01-171-35/+51
| | | | | | | | * module/system/vm/assembler.scm (process-relocs): Remove 'buf' parameter and turn into a pure function. (patch-relocs!): New procedure. Perform the side effects previously done in 'process-relocs'. (link-text-object): Adjust accordingly.
* Add test for 'string-ref' with a negative index at -O2.Ludovic Courtès2023-01-171-5/+14
| | | | | | | | | | This test would segfault prior to c0004442b7691f59a0e37869ef288eb26382ad9e. See <https://bugs.gnu.org/60488>. * test-suite/tests/strings.test ("string-ref"): Use 'with-test-prefix/c&e'. ["negative index"]: Check the reported bounds.
* Document R7RS functions related to bytevectorsDaniel Llorens2023-01-173-14/+227
| | | | | | | | | | | | | | * doc/ref/api-data.texi (Bytevectors): Fix typo in (r6:bytevector-copy), index need not be positive. Fix typos in bytevector-length, bytevector=, bytevector-fill!. New node 'Bytevector Procedures in R7RS'. (Bytevector Procedures in R7RS): Document R7RS bytevector, bytevector-copy, bytevector-copy!, bytevector-append. * doc/ref/api-io.texi (Binary I/O): Document R7RS open-output-bytevector, write-u8, read-u8, peek-u8, get-output-bytevector, open-input-bytevector, read-bytevector!, read-bytevector, write-bytevector. * doc/ref/r7rs.texi (R7RS support): Link to R7RS standard.
* Doc: clarification on regexes and encodingsJean Abou Samra2023-01-171-2/+6
| | | | | * doc/ref/api-regex.texi: make it more obviously clear that regexp matching supports only characters supported by the locale encoding.
* doc: Fix eval-when exampleJean Abou Samra2023-01-171-11/+18
| | | | | | | * doc/ref/api-macros.texi: make the macro expand to the literal date, not to a call to the date function. The example previously did not actually need eval-when and did not show the intended effect.
* build: Avoid implicit 'int' return type in configure tests.Ludovic Courtès2023-01-161-2/+2
| | | | | | | Fixes <https://bugs.gnu.org/60022>. Reported by Florian Weimer <fweimer@redhat.com>. * configure.ac: Add missing implicit 'int' return type in tests.

* Reduce redundant 'close' calls when forking on some systems.Andrew Whatson2023-01-132-3/+40
| | | | | | | | | | | | | | | | | Fixes <https://bugs.gnu.org/59321>. Reported by <hylophile@posteo.de>. Some systems provide "/proc/self/fd" which is a directory containing an entry for each open file descriptor in the current process. We use this to limit the number of close() calls needed to ensure file descriptors aren't leaked to the child process when forking. * libguile/posix.c (close_inherited_fds_slow): (close_inherited_fds): New static helper functions. (scm_spawn_process): Attempt to close inherited file descriptors efficiently using 'close_inherited_fds', falling back to the brute-force approach in 'close_inherited_fds_slow'. * NEWS: Update.

* doc: Fix minor typosColin Woodbury2022-12-092-2/+2
| | | | | | | | | | | The spelling mistake is a clear fix, but the Arrays fix might not be as obvious. Previously, with the "arrays" alias, the @ref macro would render a superfluous period after the word "arrays", rendering (at least within Emacs) as: you may wish to use see arrays. instead.

| | | | | | | | | | | | | | | If we got interrupted while waiting on our condition variable, we unlock the kernel mutex momentarily while executing asynchronous operations before putting us back into the waiting queue. However, we have to retry acquiring the mutex before getting back into the queue, otherwise it's possible that we wait indefinitely since nobody could be the owner for a while. * libguile/threads.c (lock_mutex): Try acquring the mutex after signal interruption.
