At present localdef accepts the following non-POSIX options: --list-archive [FILE] and --prefix=PATH The first allows you to list the contents of the default binary locale archive via `--list-archive` or any other archive via `--list-archive FILE` where FILE is an absolute or relative path to the archive. This patch does three things, and I have consciously not split them up into three patches because they logically belong together. (1) Enhance `--list-archive`, `--add-to-archive`, and `--delete-from-archive` to honour `--prefix=PATH`. At present the use of --prefix does not adjust the path interpreted by --list-archive FILE . This is a mistake. We should always honour --prefix in all of our output operations. The patch makes --list-archive FILE honour prefix. For example if you ran `--prefix /mnt/chroot --list-archive /usr/lib/locale/locale-archive-v2` the final path to the locale archive file would be: `/mnt/chroot/usr/lib/locale/locale-archive-v2`. Similarly --add-to-archive and --delete-from-archive honour --prefix when computing the archive to use. e.g. localedef --prefix="/home/carlos/tmp" --add-to-archive ./en_US.UTF-8 cannot create temporary file: /home/carlos/tmp/usr/lib64/locale/locale-archive.3vmNHw: No such file or directory (2) Add a `--localedir=PATH` option per BZ #19130. At present all operations are carried out against a hard-coded LOCALEDIR e.g. $(localedir) or /usr/lib/locale. This patch adds a --localedir=PATH option which allows you to change the value of LOCALEDIR used in localedef. For example if you ran `--localedir=/usr/lib64/locale --list-archive` the final path to the locale archive file would be: `/usr/lib64/locale/locale-archive`. e.g. ./locale/localedef --prefix="/home/carlos/tmp" --localedir="/alt" --add-to-archive ./en_US.UTF-8 cannot create temporary file: /home/carlos/tmp/alt/locale-archive.VCqI8z: No such file or directory (3) Add a `--archive-file=FILE`/`-a FILE` option. At present the binary locale archive name is always `locale-archive`, but it would be easier for distribution maintainers and developers if localedef could be made to scan an arbitrary file. This patch makes `--archive-file=FILE` adjust the default locale archive file name to be FILE. For example if you ran: `--prefix /mnt/croot --archive-file=locale-archive-v2` the final path to the locale archive file would be: `/mnt/chroot/usr/lib/locale/locale-archive-v2`. With (1), (2) and (3), you have full control over the locale archive selected by localedef: [prefix][localedir][archive file] | | | | | |-> --archive-file | | | |-> --localedir | |-> --prefix Sensible defaults are selected for all values based on the configuration of glibc e.g. prefix is "", localedir is "$(localedir)" and archive file is "locale-archive". (a) Use of I18NPATH, LOCPATH, and change in behaviour of ENOENT for locale-archive. The selection of the character maps is achieved by use of the I18NPATH env var, and LOCPATH env var for the location of source locale data. These environment variables do not use --prefix. Both of these variables will fallback to the default system directory during failure to find the required files, while the above settings for prefix/localedir/archive-file will create the requested binary locale archive file if not found. Note that this is a change in behaviour, previously if the non-default binary locale archive file was not found we would issue an error (only creating the default locale archive was supported). Now we treat all locale-archive files the same way. It might be argued that a "--create" mode should be used and errors issued if the file doesn't exist in all cases, but this breaks backwards compatibility and should be avoided. The only thing we break with this patch is using `--list-archive foo` to test if `foo` is present and a locale-archive file, which now returns nothing, but doesn't fail (like we did for the default locale archive). (b) Future enhancements. Future enhancements include more options to control locale source path (LOCPATH) and character map locations (I18NPATH) since falling back to the default system directories is not always desirable in a cross or sysroot'd environment. Tested on x86_64 to view locale archive files in non-standard paths and to generate locale archive files in non-standard paths.
