patch to fix --localedir configure argument

For some time, glibc has supported defining the install location of locale data files by providing the --localedir=foo argument to configure. Currently, the argument is ignored and locale data is always stored and searched for in /usr/lib(64)/locale.

Previously, there was a check in sysdeps/gnu/configure.in (and the generated file sysdeps/gnu/configure) which tested the $libdir variable in a 64-bit build, and set $libc_cv_localedir only for that case.

$libc_cv_localedir should be set in all cases, otherwise the --localedir arg is ignored, and locale data files always end up in /usr/lib(64)/locale

A patch is attached which fixes this in the tip of the upstream repository.

Comment 2 Carlos O'Donell 2012-06-19 03:40:18 UTC
Etienne,

Could you please describe in more detail exactly what was wrong before and what the new behaviour is with your patch?

For example if I configure without --localedir, has the behaviour changed? Are the locale files still installed in the same place?

Thanks.
Comment 3 Etienne Le Sueur 2012-06-21 04:44:48 UTC
Hi Carlos,

The explanation is complex due to the nature of the build infrastructure, but here goes:

I want to change the location of the locale-archive in the installation. By default it is installed as /usr/lib(64)/locale/locale-archive. I thought I would be able to do this with the --localedir argument to configure. But it turns out that doesn't work.

The locale archive is placed in LOCALEDIR/locale-archive, and LOCALEDIR is defined using -D in CFLAGS from a configure variable called $localedir. $localedir is sourced from $libc_cv_localedir in config.make.in:14

On 32-bit builds, $libc_cv_localedir is never set, hence $localedir is always empty and it defaults to ${libdir}/locale (from Makeconfig:222) and can't be changed with --localedir.

On 64-bit builds, $libc_cv_localedir is set to ${exec_dir}/lib64/locale (see sysdeps/gnu/configure:20) only if --prefix=/usr is specified, otherwise it is left empty, and $localedir again defaults to ${libdir}/locale.

The glibc build infrastructure has some special case scripting for the case where --prefix=/usr, which is where I decided to make the fix.

I am not an expert in locales at all, but it seems to me that something is broken if I can't change the location of the locale-archive with --localedir.

Does anyone own the locale code?

The development community owns the code, we all need to step up to maintain the code. Petr Baudis is our locale expert, but that doesn't mean he owns the locale configuration code.

Your explanation here is perfect, it's exactly the explanation I was expecting in the *initial* submission of the ticket. You explain what you need and why, and what's wrong with the current code.

The target milestone is already set for 2.17, we are in the 2.16 code freeze right now. Once we are out of the code freeze we'll start looking at the 2.17 issues. Your patch is a good starting place.

Next steps:
* Wait for the 2.16 freeze to thaw.
* Work with the maintainers to get your patch checked in.

In the meantime I suggest reviewing:
http://sourceware.org/glibc/wiki/Contribution%20checklist

Note: Your patch is not legally significant since it's a simple 2 line change. However, if you wish to continue contributing to the project we will need a copyright assignment in place.

patch to fix --localedir configure argument

You seem to change the behaviour.

With your change I get on i686 via config.make (without specifying --localedir)
datarootdir = ${prefix}/share
localedir = ${datarootdir}/locale

Previously localedir was unset and thus Makeconfig set it to:
localedir = $(libdir)/locale

So, now it's /usr/share/locale and previously it was /usr/lib/locale.

This change is not acceptable. Let me work on a better patch.
Comment 7 Andreas Schwab 2012-07-26 14:05:35 UTC
--localedir specifies the location of the gettext message files.  It is _not_ meant for the locale data files.  If localedir should be configurable, it needs a new option.
Comment 8 Carlos O'Donell 2012-07-26 16:10:39 UTC
Waiting for updated patch from contributor that creates a new configuration option to set the locale data file directory.
Comment 9 travneff 2014-05-15 18:06:36 UTC
Just faced it.

Firstly, explicit --localedir specification seems ignored.

Secondly, Makeconfig contains one default value [$(libdir)/locale] and configure lists another [DATAROOTDIR/locale].
The latter is newer and seems better, as for me.

Could we change Makeconfig default value to $(datadir)/locale, at least?
Comment 10 Dimitri John Ledkov 2015-03-11 10:43:46 UTC
I believe I am affected as well.

Somehow the locale-archive ends up in/usr/lib64/locale/locale-archive for me, which is not where systemd upstream expects it to be at.
I'm trying at the moment:
--localedir=/usr/lib/locale \
libc_cv_localedir=/usr/lib/locale

At the end of configure options, in hope that it will be honoured.

As discussed on libc-alpha:
https://sourceware.org/ml/libc-alpha/2015-10/msg00684.html

The --localedir option needs fixing, and a new option created for locale archive.

Renamed internal localedir uses to complocaledir to prepare the way for a fix here.

Author: Carlos O'Donell <carlos@systemhalted.org>
Date:   Fri Nov 27 10:09:45 2015 -0500

    Rename localedir to complocaledir (bug 14259).
    
    In preparation to fix the --localedir configure argument we must
    move the existing conflicting definition of localedir to a more
    appropriate name. Given that all current internal uses of localedir
    relate to the compiled locales we rename to complocaledir.

The GNU C Library
=================

The GNU C Library version 2.23 is now available.

The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.

The GNU C Library is primarily designed to be a portable
and high performance C library.  It follows all relevant
standards including ISO C11 and POSIX.1-2008.  It is also
internationalized and has one of the most complete
internationalization interfaces known.

The GNU C Library webpage is at http://www.gnu.org/software/libc/

Packages for the 2.23 release may be downloaded from:
        http://ftpmirror.gnu.org/libc/
        http://ftp.gnu.org/gnu/libc/

The mirror list is at http://www.gnu.org/order/ftp.html

NEWS for version 2.23
=====================

* Unicode 8.0.0 Support: Character encoding, character type info, and
  transliteration tables are all updated to Unicode 8.0.0, using new
  and/or improved generator scripts contributed by Mike FABIAN (Red Hat).
  These updates cause user visible changes, such as the fixes for bugs
  89, 16061, and 18568.

* sched_setaffinity, pthread_setaffinity_np no longer attempt to guess the
  kernel-internal CPU set size.  This means that requests that change the
  CPU affinity which failed before (for example, an all-ones CPU mask) will
  now succeed.  Applications that need to determine the effective CPU
  affinities need to call sched_getaffinity or pthread_getaffinity_np after
  setting it because the kernel can adjust it (and the previous size check
  would not detect this in the majority of cases).

* The fts.h header can now be used with -D_FILE_OFFSET_BITS=64.  With LFS
  the following new symbols are used: fts64_children, fts64_close,
  fts64_open, fts64_read and fts64_set.

* getaddrinfo now detects certain invalid responses on an internal netlink
  socket.  If such responses are received, an affected process will
  terminate with an error message of "Unexpected error <number> on netlink
  descriptor <number>" or "Unexpected netlink response of size <number> on
  descriptor <number>".  The most likely cause for these errors is a
  multi-threaded application which erroneously closes and reuses the netlink
  file descriptor while it is used by getaddrinfo.

* A defect in the malloc implementation, present since glibc 2.15 (2012) or
  glibc 2.10 via --enable-experimental-malloc (2009), could result in the
  unnecessary serialization of memory allocation requests across threads.
  The defect is now corrected.  Users should see a substantial increase in
  the concurent throughput of allocation requests for applications which
  trigger this bug.  Affected applications typically create create and
  destroy threads frequently.  (Bug 19048 was reported and analyzed by
  Ericsson.)

* There is now a --disable-timezone-tools configure option for disabling the
  building and installing of the timezone related utilities (zic, zdump, and
  tzselect).  This is useful for people who build the timezone data and code
  independent of the GNU C Library.

* The obsolete header <regexp.h> has been removed.  Programs that require
  this header must be updated to use <regex.h> instead.

* The obsolete functions bdflush, create_module, get_kernel_syms,
  query_module and uselib are no longer available to newly linked binaries;
  the header <sys/kdaemon.h> has been removed.  These functions and header
  were specific to systems using the Linux kernel and could not usefully be
  used with the GNU C Library on systems with version 2.6 or later of the
  Linux kernel.

* Optimized string, wcsmbs and memory functions for IBM z13.
  Implemented by Stefan Liebler.

* Newly linked programs that define a variable called signgam will no longer
  have it set by the lgamma, lgammaf and lgammal functions.  Programs that
  require signgam to be set by those functions must ensure that they use the
  variable provided by the GNU C Library and declared in <math.h>, without
  defining their own copy.

* The minimum GCC version that can be used to build this version of the GNU
  C Library is GCC 4.7.  Older GCC versions, and non-GNU compilers, can
  still be used to compile programs using the GNU C Library.

Security related changes:

* An out-of-bounds value in a broken-out struct tm argument to strftime no
  longer causes a crash.  Reported by Adam Nielsen.  (CVE-2015-8776)

* The LD_POINTER_GUARD environment variable can no longer be used to disable
  the pointer guard feature.  It is always enabled.  Previously,
  LD_POINTER_GUARD could be used to disable security hardening in binaries
  running in privileged AT_SECURE mode.  Reported by Hector Marco-Gisbert.
  (CVE-2015-8777)

* An integer overflow in hcreate and hcreate_r could lead to an
  out-of-bounds memory access.  Reported by Szabolcs Nagy.  (CVE-2015-8778)

* The catopen function no longer has unbounded stack usage.  Reported by
  Max.  (CVE-2015-8779)

* The nan, nanf and nanl functions no longer have unbounded stack usage
  depending on the length of the string passed as an argument to the
  functions.  Reported by Joseph Myers.  (CVE-2014-9761)

* A stack-based buffer overflow was found in libresolv when invoked from
  libnss_dns, allowing specially crafted DNS responses to seize control
  of execution flow in the DNS client.  The buffer overflow occurs in
  the functions send_dg (send datagram) and send_vc (send TCP) for the
  NSS module libnss_dns.so.2 when calling getaddrinfo with AF_UNSPEC
  family.  The use of AF_UNSPEC triggers the low-level resolver code to
  send out two parallel queries for A and AAAA.  A mismanagement of the
  buffers used for those queries could result in the response of a query
  writing beyond the alloca allocated buffer created by
  _nss_dns_gethostbyname4_r.  Buffer management is simplified to remove
  the overflow.  Thanks to the Google Security Team and Red Hat for
  reporting the security impact of this issue, and Robert Holiday of
  Ciena for reporting the related bug 18665. (CVE-2015-7547)

commit 314f6deec991e8239ad3fb15aeed186fabe3483f
Author: Carlos O'Donell <carlos@systemhalted.org>
Date:   Wed Feb 24 20:06:04 2016 -0500

    Enable --localedir to set message catalog directory (Bug 14259)
    
    In 1999 the project split "localedir" into "localedir" (path to compiled
    locale archives) and "msgcatdir" (path to message catalogs). This
    predates the 2002 change in the GNU Coding Standard to document the use
    of "localedir" for the path to the message catalogs. It appears that
    newlib, gcc, and several other projects also used "msgcatdir" at one
    point or another in the past, and so it is in line with historical
    precedent that glibc would also use "msgcatdir." However, given that the
    GNU Coding Standard uses "localedir", we will switch to that for
    consistency as a GNU project. Previous uses of --localdir didn't work
    anyway (see bug 14259).
    
    I am committing this patch in the understanding that nobody would object
    to fixing #14259 as part of aligning our variable usage to the GNU
    Coding Standard.
    
    Given that previous "localedir" uses were converted to "complocaledir"
    by [1], we can now convert "msgcatdir" to "localedir" and complete the
    transition. With an addition to config.make.in we also fix bug 14259 and
    allow users to specify the locale dependent data directory with
    "--localedir" at configure time. There is still no way to control at
    configure time the location of the *compiled* locale directory.
    
    Tested on x86_64 with no regressions.
    
    Tested using "--localedir" to specify alternate locale dependent data
    directory and verified with "make install DESTDIR=/tmp/glibc".

Comment 16 Carlos O'Donell 2016-02-25 01:12:14 UTC
Created Bug 19723:
Add --complocaledir option to change install directory of compiled locales e.g. locale-archive. 
https://sourceware.org/bugzilla/show_bug.cgi?id=19723

To track the changes required to enable configuration of the compiled locales directory.

This bug however is fixed. You can now use --localedir to set the message catalog directory as specified by the GNU Coding standard.
