* maint.mk: sort file names *after* new transformationJim Meyering2011-03-201-1/+1
| | | | | | * top/maint.mk (sc_po_check): Sorting before removing the $(srcdir)/ prefix would have led to an unwarranted failure in GNU parted. Sort after that transformation.
* maint.mk: fix po-file syntax-check ruleJim Meyering2011-03-191-1/+1
| | | | | * top/maint.mk (sc_po_check): Fix fatal typo in yesterday's change. Patch by Bruno Haible.
* maint.mk: let po check work in VPATH buildEric Blake2011-03-181-3/+3
| | | | | | | | * top/maint.mk (po_file): Allow cfg.mk override. (sc_po_check): Allow VPATH use. Reported by Jiri Denemark. Signed-off-by: Eric Blake <eblake@redhat.com>
* maint.mk: allow fine-grained syntax-check exclusion via Make variablesJim Meyering2011-03-161-2/+15
| | | | | | | | | Before, you would have had to create one .x-sc_ file per rule in order to exempt offending files. Now, you may instead use a Make variable -- usually defined in cfg.mk -- whose name identifies the affected rule. * top/maint.mk (_sc_excl): Define. (VC_LIST_EXCEPT): Use it to exclude names on a per-rule basis. (_sc_search_regexp): When not using VC_LIST_EXCEPT, exclude here, too.
* maint.mk: relax a regexp to accommodate other formatting stylesJim Meyering2011-03-111-1/+1
| | | | | * top/maint.mk (sc_unmarked_diagnostics): Allow 0 or 1 space between "ngettext" and the following "(".
* maint.mk: suppress a syntax check false positivePádraig Brady2011-03-111-1/+1
| | | | | * top/maint.mk (sc_unmarked_diagnostics): Don't warn when diagnostics are marked with ngettext.
* maint.mk: detect missing-NL-at-EOF, tooJim Meyering2011-02-251-5/+12
| | | | | | | | | * top/maint.mk (sc_prohibit_empty_lines_at_EOF): Adjust so that it also detects when a file lacks a newline at EOF. (require_exactly_one_NL_at_EOF_): Renamed from detect_empty_lines_at_EOF_. I opted not to rename the rule, since people may well have .x-sc_... file names tied to the existing name. Suggested by Eric Blake.
* maintainer-makefile: make syntax-check a no-op from tarballsEric Blake2011-02-161-2/+7
| | | | | | | | | * top/maint.mk (no-vc-detected): New rule. (local-checks-available): Use it to avoid hanging if someone tries 'make syntax-check' from a tarball. Also append to any non-syntax checks already defined in cfg.mk. Signed-off-by: Eric Blake <eblake@redhat.com>
* maint.mk: add syntax-check rule: detect unnecessary #include <stddef.h>Jim Meyering2011-01-231-0/+7
| | | | * top/maint.mk (sc_prohibit_stddef_without_use): New rule.
* maintainer-makefile: work with older git for submodule checkEric Blake2011-01-211-2/+2
| | | | | | | | * top/maint.mk (public-submodule-commit): Rewrite to avoid merge-base --independent, which Ubuntu 10.04 git 1.7.0.4 lacks. Reported by Matthias Bolte. Signed-off-by: Eric Blake <eblake@redhat.com>
* maint.mk: adjust variable name to be consistent with other gl_ varsJim Meyering2011-01-211-3/+3
| | | | | * top/maint.mk (gl_public_submodule_commit): Rename the variable to be lower case.
* maint.mk: make "check" depend on public-submodule-commit by defaultJim Meyering2011-01-201-0/+8
| | | | * top/maint.mk (GL_PUBLIC_SUBMODULE_COMMIT): New overridable variable.
* maint.mk: improve the public-submodule-commit ruleJim Meyering2011-01-201-2/+3
| | | | | | | | * top/maint.mk (public-submodule-commit): Prefix with $(AM_V_GEN), to suppress printing of its commands... unless V=1. Add git submodule's --quiet option to suppress printing of e.g., "Entering gnulib" output. "cd" into $(srcdir) before running git submodule.
* maint.mk: improve sc_prohibit_strcmp regexEric Blake2011-01-061-3/+3
| | | | | | | | * top/maint.mk (sc_prohibit_strcmp): Detect strcmp()!=0, as documented. Also, detect strcmp((expr),expr) == 0. Exempt the definition of STRNEQ. Signed-off-by: Eric Blake <eblake@redhat.com>
* maint.mk: add pre-release check to ensure submodule commits are publicEric Blake2011-01-061-1/+17
| | | | | | * top/maint.mk (public-submodule-commit): New rule. (submodule-checks): New variable. (alpha beta stable): Depend on the variable.
* maint: update almost all copyright ranges to include 2011Jim Meyering2011-01-012-2/+2
| | | | Run the new "make update-copyright" rule.
* maint.mk: add a URL discussing the no-@acronym policyJim Meyering2010-11-191-1/+2
| | | | * top/maint.mk (sc_texinfo_acronym): Add a URL in a comment.
* maint.mk: rename variable: s/noteworthy/gl_noteworthy_news_/Jim Meyering2010-11-141-2/+2
| | | | | * top/maint.mk (gl_noteworthy_news_): Rename from "noteworthy" and move definition closer to sole use.
* maintainer-makefile: cover a few more filesEric Blake2010-11-131-1/+1
| | | | | | | * top/maint.mk (sc_prohibit_test_double_equal): Also cover shell scripts generated within C files, for libvirt. Signed-off-by: Eric Blake <eblake@redhat.com>
* maint.mk: tighten "test a == b" checkJim Meyering2010-11-131-0/+1
| | | | | | | * top/maint.mk (sc_prohibit_test_double_equal): Restrict this test to files that contain something like #!/bin/sh. Without this, coreutils would get two false positives in the comments of C source files.
* maintainer-makefile: prohibit test x == xEric Blake2010-11-121-0/+6
| | | | | | | * top/maint.mk (sc_prohibit_test_double_equal): New rule. Based on a report by Matthias Bolte. Signed-off-by: Eric Blake <eblake@redhat.com>
* maintainer-makefile: check for i18n setupEric Blake2010-11-121-1/+10
| | | | | | | * top/maint.mk (sc_bindtextdomain): Check for evidence that _() will likely work. Signed-off-by: Eric Blake <eblake@redhat.com>
* GNUmakefile: handle "stable" target, not "major"Jim Meyering2010-10-151-1/+1
| | | | | | * top/GNUmakefile (_is-dist-target): s/major/stable/ to match the lists in maint.mk and announce-gen. Without this, "make stable" would fail to ensure that $(VERSION) is up to date.
* maint.mk: avoid unexpanded \n in two diagnosticsJim Meyering2010-09-181-5/+7
| | | | | | | | * top/maint.mk (sc_prohibit_always_true_header_tests): Don't use a literal \n in a halt=... assignment. It would not be expanded, and the two \n bytes would appear in the diagnostic output rather than the desired newline. Use halt=$$(printf ... instead. (sc_vulnerable_makefile_CVE-2009-4029): Likewise.
* maint.mk: avoid obscure sc_copyright_check failure in coreutilsJim Meyering2010-09-041-1/+1
| | | | | | | * top/maint.mk (v_etc_file): Prepend $(gnulib_dir)/, to avoid false positives (whose names may be ill-chosen) when searching non-VC'd files. Otherwise, a file named "a b/lib/version-etc.c" would cause a false-positive.
* maint.mk: make the news-check rule more configurablePeter Simons2010-06-081-2/+8
| | | | | * top/maint.mk (news-check-lines-spec) New variable. (news-check): Use "sed -n 1,10p" in place of "head".
* git-version-gen: take a sed script to transform the git tagLudovic Courtès2010-05-281-2/+4
| | | | | | | * build-aux/git-version-gen (tag_sed_script): New variable. Use it to transform the output of "git describe" to the canonical form. * top/GNUmakefile (_curr-ver): Pass $(git-version-gen-tag-sed-script) as a second argument to `git-version-gen'.
* maint.mk: also prohibit "#undef" of always-defined symbolsJim Meyering2010-05-271-2/+3
| | | | | | | * top/maint.mk (def_sym_regex): Handle #undef as well as #define. Allow more than one space before the symbol name. (sc_prohibit_always-defined_macros): Use grep's -E, now that the regexp uses alternation.
* maint.mk: avoid echo -eEric Blake2010-05-261-3/+4
| | | | | | | | | | | | There are still other potentially non-portable uses of echo throughout this file, if $(ME) contains \ or starts with -, but this patch is a trivial step in the right direction. * top/maint.mk (gzip_rsyncable): Convert all uses of echo -* to printf. Reported by Matthias Bolte. Signed-off-by: Eric Blake <eblake@redhat.com>
* maint.mk: tweak preceding changeJim Meyering2010-05-111-1/+1
| | | | | | * top/maint.mk (gl_extract_significant_defines_): Make exclusion regexps tighter by anchoring at EOL, and make the new group "shy" for slightly decreased overhead.
* maint.mk: gnulib doesn't guarantee NSIGEric Blake2010-05-111-2/+3
| | | | | | | | | | Gnulib conditionally defines NSIG to 32 for some platforms. But since NSIG is not mandated by standards, and there are platforms with 64 signals, we should not promise that NSIG is guaranteed. * top/maint.mk (gl_extract_significant_defines_): Exclude NSIG. Signed-off-by: Eric Blake <eblake@redhat.com>
* maint.mk: avoid using a temporary file in the always-defined-macros checkJim Meyering2010-05-101-15/+8
| | | | | | | | * top/maint.mk (.re-defmac): Remove rule. (gl_trap_): Remove definition. (sc_prohibit_always-defined_macros): Rewrite not to create and depend on a temporary file. Instead, depend on GNU grep's ability to read a list of regular expressions from stdin when given "-f -".
* maint.mk: improve sc_cross_check_PATH_usage_in_testsJim Meyering2010-05-091-12/+14
| | | | | | | | | | | | | | | With my recent change in init.sh from the two-line form: -# : ${srcdir=.} -# . "$srcdir/init.sh"; path_prepend_ . +# . "${srcdir=.}/init.sh"; path_prepend_ . I noticed that using the one-line form would cause this test to fail with a false-positive, or to stop working altogether, depending on whether help-version changed or all the tests did. * top/maint.mk (_hv_regex): Remove this definition. (_hv_regex_weak): Use a weak regex to select all init.sh-sourcing files. (_hv_regex_strong): Use a stronger regex to check for conformance. (sc_cross_check_PATH_usage_in_tests): Rewrite to use the above. Give a separate diagnostic for lack of conforming use.
* maint.mk: prohibit definition of symbols defined by gnulibJim Meyering2010-05-091-0/+44
| | | | | * top/maint.mk (sc_prohibit_always-defined_macros): Reject the definition of symbols defined by gnulib.
* maint.mk: allow to pass options to gendocs.shJim Meyering2010-05-031-1/+6
| | | | | * top/maint.mk (web-manual): Pass gendocs_options_ to gendocs.sh. (gendocs_options_): New overridable variable.
* maint.mk, announce-gen: allow project-specific announcement mail headersJim Meyering2010-05-031-0/+8
| | | | | | | * top/maint.mk (translation_project_): Define default. (announcement_Cc_, announcement_mail_headers_): Likewise. (announcement): Invoke announce-gen with new --mail-headers option. * build-aux/announce-gen: New option: --mail-headers=HEADERS.
* maint.mk: prohibit unwarranted use of <strings.h>Jim Meyering2010-05-031-0/+7
| | | | | | * top/maint.mk (sc_prohibit_strings_without_use): Reject inclusion of strings.h in a file that does not also use strcasecmp, strncasecmp, ffs or ffsll.
* maint.mk: remove obsolete commentsJim Meyering2010-05-031-10/+0
| | | | * top/maint.mk: Remove stale, commented-out rules.
* top/maint.mk (indent): Run twice to produce idempotent results.Simon Josefsson2010-04-291-0/+2
|
* maint.mk: fix a bug introduced in last changeJim Meyering2010-04-271-1/+1
| | | | | | * top/maint.mk (gl_assured_headers_): Now that all names are on one line, use sed's "g" modifier. Note that while the \.in\.h LHS is not anchored to end of word, it should be adequate.
* maint.mk: avoid side-effect in latest syntax-checkJim Meyering2010-04-271-7/+8
| | | | | | * top/maint.mk (sc_prohibit_always_true_header_tests): Rework not to run commands via $(shell...), and hence to incur cost only when the new rule is actually run.
* maint.mk: syntax-check: prohibit HAVE_<header>_H that are always trueJim Meyering2010-04-271-0/+22
| | | | | | | | Derive the list of guaranteed header names from gnulib/lib/*.in.h, and use that to create a regexp used to detect all #if HAVE_..._H uses. * top/maint.mk (sc_prohibit_always_true_header_tests): New rule. (gl_assured_headers_, az_, AZ_): Define. (gl_header_upper_case_or_, gl_have_header_regex_): Define.
* top/maint.mk (sc_prohibit_backup_files): Prohibit checked in backup files.Simon Josefsson2010-04-221-0/+6

* maint.mk: use gnu-style indentation in an embedded perl scriptJim Meyering2010-04-171-10/+12
| | | | | * top/maint.mk (detect_empty_lines_at_EOF_): Clean up formatting. Rename variable: s/two/last_two_bytes/
* maint.mk: texinfo_suffix_re_: correct the default regexpJim Meyering2010-04-151-1/+1
| | | | * top/maint.mk (texinfo_suffix_re_): Fix default regexp.
* top/maint.mk (sc_texinfo_acronym): Improve filename regexp.Simon Josefsson2010-04-151-2/+3

* maint.mk: generate more concise timing data for syntax-check rulesJim Meyering2010-04-121-1/+1
| | | | | * top/maint.mk ($(sc_z_rules_)): Remove the ":", "sc_" prefix and " done" from each line that reports a syntax-check test duration.
* maint.mk: don't include dist-check.mkJim Meyering2010-04-111-2/+0
| | | | * top/maint.mk: Remove bogus include directive.
* maint.mk: improve empty-line-at-EOF checkJim Meyering2010-04-111-10/+23
| | | | | | | * top/maint.mk (sc_prohibit_empty_lines_at_EOF): Use Perl-based solution, rather than tail+Perl-based one. The latter would read a few kilobytes from the end of each file, and did not handle empty files properly.
* maint.mk: print the elapsed time for each syntax-check ruleJim Meyering2010-04-111-2/+17
| | | | | | * top/maint.mk (sc_m_rules_): Save start time in a file. (sc_z_rules_): New rules: remove temp file and print elapsed time. (local-check): Interpose the .z rules
