'call-with-current-continuation' is overkill and not quite what we
want. 'let/ec' is supported in Guile 2.0, 2.2, and 3.0.
* src/mcron/base.scm (run-job-loop): Use 'let/ec' instead of
'call-with-current-continuation'.
<libguile.h> in Guile 2.x used to include these, but this is no longer
the case with 3.0.
* src/cron.c, src/mcron.h: Include <string.h>.
* src/utils.c: Include <stdio.h>.
This allows users to configure the Mail Transfert Agent (MTA) of their
choice.
* configure.ac: Add '--with-sendmail' option.
(SENDMAIL): Default to 'sendmail -t'.
* NEWS: Announce it.
* src/mcron/redirect.scm (with-mail-out): Assume the MTA is reading the
message for recipients.
* build-aux/guix.scm: Remove 'which' from the native-inputs.
* README: Do not include the version number. Refer to "HACKING" when
"INSTALL" is not available. Tell about the "--disable-multi-user"
configure option.
It seems that it is not useful to catch 'misc-error exception when
calling 'getopt-long'. Since 'parse-args' purpose was only to catch
this particular error, it can be deleted.
* src/mcron/utils.scm (parse-args): Remove.
* src/mcron/job-specifier.scm (configuration-user): Box it using
SRFI-111 to be explicit about the mutability of this object.
(job): Adapt.
(set-configuration-user): Adapt and use 'get-user'.
* tests/job-specifier.scm ("set-configuration-user: passwd entry")
("set-configuration-user: invalid uid", "set-configuration-user: uid")
("set-configuration-user: invalid spec")
("set-configuration-user: name"): New tests.
This is a follow-up to commit 913e3c65e4.
Since 'next-...-from' procedures now uses an '#:optional' argument
instead of a dotted optional arguments list, 'bump-time' doesn't need to
unwrap VALUE-LIST anymore.
* src/mcron/job-specifier.scm (bump-time): Pass VALUE-LIST directly to
'%find-best-next'.
* tests/job-specifier.scm ("next-hour-from"): New test.
* NEWS: Update.
Reported-by: Ludovic Courtès <ludo@gnu.org>
The behavior of the 'min' procedure which converts its parameters to
inexact numbers when at least one of them is inexact was causing
'%find-best-next' to always return real numbers.
* src/mcron/job-specifier.scm (%find-best-next): Preserve the exactness
of numbers in NEXT-LIST.
* tests/job-specifier.scm ("%find-best-next: exact"): New test.

Fetching third-party files inside a make rule is convenient and less
error prone since 'make' has access to '$srcdir'.
* build-aux/gnu-fetch: Delete.
* maint.mk (WGET, git_sv_host, sv_git_am, sv_git_gl)
(fetchfiles): New macros.
(fetch): New target.
* HACKING <Updating auxilary scripts>: Update instructions.
* src/mcron/environment.scm (current-environment-mods): Rename to ...
(%current-environment-mods): ... this. Box it using SRFI-111 to be
explicit about the mutability of this object.
(get-current-environment-mods-copy, clear-environment-mods)
(append-environment-mods): New '#:ENVIRON' argument.
* src/mcron/base.scm (number-children): Box it using SRFI-111 to be
explicit about the mutability of this object.
(update-number-children!): New procedure.
(run-job, child-cleanup): Use it.
* tests/base.scm ("update-number-children!: 1+")
("number-children: init", "update-number-children!: 1-"): New tests.
