From e83031c84de410cb19c96a4084b95f26619ce5a9 Mon Sep 17 00:00:00 2001 From: Alexander Bokovoy Date: Thu, 28 Aug 2003 17:16:27 +0000 Subject: Refactor charset plugins a bit and add CP437 module. Now all 8-bit charsets with gaps (not all symbols defined) could be produced through one macro -- SMB_GENERATE_CHARSET_MODULE_8_BIT_GAP(CHARSETNAME) within source file with three charset tables. Full source code for such modules can be generated by source/script/gen-8bit-gap.sh script which was taken from GNU libc and changed slightly to follow our data types and structure. (This used to be commit 37042c7bc0f349370e93e4bed37d8fa371013247) --- source3/Makefile.in | 6 + source3/configure.in | 5 +- source3/include/charset.h | 87 +++++++++ source3/modules/CP437.c | 359 ++++++++++++++++++++++++++++++++++++++ source3/modules/CP850.c | 76 +------- source3/script/.cvsignore | 1 + source3/script/gap.awk | 39 +++++ source3/script/gaptab.awk | 48 +++++ source3/script/gen-8bit-gap.sh.in | 51 ++++++ 9 files changed, 597 insertions(+), 75 deletions(-) create mode 100644 source3/modules/CP437.c create mode 100644 source3/script/gap.awk create mode 100644 source3/script/gaptab.awk create mode 100755 source3/script/gen-8bit-gap.sh.in diff --git a/source3/Makefile.in b/source3/Makefile.in index 2f88142ff2..bb5a1656d6 100644 --- a/source3/Makefile.in +++ b/source3/Makefile.in @@ -288,6 +288,7 @@ XML_OBJ = passdb/pdb_xml.o MYSQL_OBJ = passdb/pdb_mysql.o DEVEL_HELP_WEIRD_OBJ = modules/weird.o DEVEL_HELP_CP850_OBJ = modules/CP850.o +DEVEL_HELP_CP437_OBJ = modules/CP437.o GROUPDB_OBJ = groupdb/mapping.o @@ -1071,6 +1072,11 @@ bin/CP850.@SHLIBEXT@: $(DEVEL_HELP_CP850_OBJ:.o=.po) @$(SHLD) $(LDSHFLAGS) -o $@ $(DEVEL_HELP_CP850_OBJ:.o=.po) \ @SONAMEFLAG@`basename $@` +bin/CP437.@SHLIBEXT@: $(DEVEL_HELP_CP437_OBJ:.o=.po) + @echo "Building plugin $@" + @$(SHLD) $(LDSHFLAGS) -o $@ $(DEVEL_HELP_CP437_OBJ:.o=.po) \ + @SONAMEFLAG@`basename $@` + bin/xml.@SHLIBEXT@: $(XML_OBJ:.o=.po) @echo "Building plugin $@" @$(SHLD) $(LDSHFLAGS) -o $@ $(XML_OBJ:.o=.po) @XML_LIBS@ \ diff --git a/source3/configure.in b/source3/configure.in index c8b5aa4b2d..9998d3a235 100644 --- a/source3/configure.in +++ b/source3/configure.in @@ -288,7 +288,7 @@ dnl These have to be built static: default_static_modules="pdb_smbpasswd pdb_tdbsam rpc_lsa rpc_samr rpc_reg rpc_lsa_ds rpc_wks rpc_net rpc_dfs rpc_srv rpc_spoolss auth_rhosts auth_sam auth_unix auth_winbind auth_server auth_domain auth_builtin" dnl These are preferably build shared, and static if dlopen() is not available -default_shared_modules="vfs_recycle vfs_audit vfs_extd_audit vfs_netatalk vfs_fake_perms vfs_default_quota vfs_readonly vfs_cap charset_CP850" +default_shared_modules="vfs_recycle vfs_audit vfs_extd_audit vfs_netatalk vfs_fake_perms vfs_default_quota vfs_readonly vfs_cap charset_CP850 charset_CP437" if test "x$developer" = xyes; then default_static_modules="$default_static_modules rpc_echo" @@ -4027,6 +4027,7 @@ SMB_SUBSYSTEM(IDMAP,sam/idmap.c) SMB_MODULE(charset_weird, modules/weird.o, "bin/weird.$SHLIBEXT", CHARSET) SMB_MODULE(charset_CP850, modules/CP850.o, "bin/CP850.$SHLIBEXT", CHARSET) +SMB_MODULE(charset_CP437, modules/CP437.o, "bin/CP437.$SHLIBEXT", CHARSET) SMB_SUBSYSTEM(CHARSET,lib/iconv.c) SMB_MODULE(auth_rhosts, \$(AUTH_RHOSTS_OBJ), "bin/rhosts.$SHLIBEXT", AUTH) @@ -4089,7 +4090,7 @@ dnl Remove -I/usr/include/?
