From 5aa8ff620ef68811c5a7dd5d5bbac1c078730a2a Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 21 Apr 1998 18:15:51 +0000 Subject: Update. 1998-04-21 18:00 Ulrich Drepper * iconv/gconv.c (__gconv): Remove bogus input buffer size computation. * iconv/gconv_open.c (__gconv_open): Initialize outbufend element. * iconv/gconv_simple.c (__gconv_transform_internal_ascii): Don't use character in comparison with uint32_t. (__gconv_transform_internal_utf8): Specify MAX_NEEDED_TO. (__gconv_transform_utf8_internal): Specify MAX_NEEDED_FROM. Optimize BODY a bit. * iconv/loop.c: Require MIN_NEEDED_INPUT and MIN_NEEDED_OUTPUT to be defined. * iconv/skeleton.c: Also reset converted counter in case of an error. Call reset function using correct value for output buffer start. * iconvdata/Makefile: Re-enable tests. * iconvdata/iso8859-1.c: Swap MIN_NEEDED_INPUT and MIN_NEEDED_OUTPUT value for to-conversion. * iconvdata/TESTS: Add new third column. * iconvdata/run-iconv-test.sh: Add support for charsets which are not ASCII based. * iconvdata/testdata/suntzus: New file. * elf/dl-minimal.c (__strtol_internal): Increment pointer to string while reading. Correctly used base. Little optimization. (__strtoul_internal): Likewise. * elf/rtld.c (dl_main): Test to avoid duplicate call of _dl_init_paths was wrong. Use explicit variable. 1998-04-20 23:49 Zack Weinberg * configure.in: Check for awk. * config.make.in: Add AWK to be substituted. * manual/xtract-typefun.awk: Rewrite to eliminate gawk extensions. * manual/users.texi: Fix typo exposed by above rewrite. * Makefile: Invoke awk using AWK variable. * csu/Makefile: Likewise. * elf/Makefile: Likewise. * mach/Makefile: Likewise. * manual/Makefile: Likewise. * sysdeps/gnu/Makefile: Likewise. * sysdeps/mach/hurd/Makefile: Likewise. * sysdeps/unix/Makefile: Likewise. * timezone/Makefile: Likewise. 1998-04-10 Gordon Matzigkeit * sysdeps/gnu/errlist.awk (ERR_REMAP): Implement error code to array index translation. (SYS_ERRLIST_ALIAS, SYS_NERR_ALIAS): Make weak aliases only if these are defined. * sysdeps/mach/hurd/Dist: Add errlist.c to distribution. * sysdeps/mach/hurd/errlist.c: New file. (ERR_TRANSLATE): Map Hurd error codes into errlist indices. (_hurd_errlist): The Hurd error list doesn't have Unix sys_errlist semantics, so rename it. 1998-04-16 Andreas Schwab * iconvdata/run-iconv-test.sh: Make portable. Always test all conversions. 1998-04-21 12:30 H.J. Lu * wcsmbs/wcsrtombs.c (__wcsrtombs): Initialize result to 0. * wcsmbs/wcsnrtombs.c: Likewise. 1998-04-21 Ulrich Drepper * sysdeps/generic/dl-sysdep.c: Handle _dl_hwcap correctly. * wcsmbs/btowc.c (__btowc): Declare inptr as const char *. * time/strftime.c (my_strftime): Initialize pad variable in declaration. * iconvdata/big5.c: Don't use character constants in comparisons with unsigned value. * sysdeps/generic/setutxent.c: New file. * sysdeps/generic/getutxent.c: New file. * sysdeps/generic/endutxent.c: New file. * sysdeps/generic/getutxid.c: New file. * sysdeps/generic/getutxline.c: New file. * sysdeps/generic/pututxline.c: New file. * sysdeps/generic/utmpxname.c: New file. * sysdeps/generic/updwtmpx.c: New file. --- iconv/gconv_simple.c | 110 +++++++++++++++++++++++++++------------------------ 1 file changed, 59 insertions(+), 51 deletions(-) (limited to 'iconv/gconv_simple.c') diff --git a/iconv/gconv_simple.c b/iconv/gconv_simple.c index f2fec12fb8..95b4a66daf 100644 --- a/iconv/gconv_simple.c +++ b/iconv/gconv_simple.c @@ -181,7 +181,7 @@ internal_ucs4_loop (const unsigned char **inptrp, const unsigned char *inend, #define LOOPFCT FROM_LOOP #define BODY \ { \ - if (*((uint32_t *) inptr) > '\x7f') \ + if (*((uint32_t *) inptr) > 0x7f) \ { \ /* This is no correct ANSI_X3.4-1968 character. */ \ result = GCONV_ILLEGAL_INPUT; \ @@ -208,6 +208,7 @@ internal_ucs4_loop (const unsigned char **inptrp, const unsigned char *inend, #define MIN_NEEDED_INPUT MIN_NEEDED_FROM #define MIN_NEEDED_OUTPUT MIN_NEEDED_TO +#define MAX_NEEDED_OUTPUT MAX_NEEDED_TO #define LOOPFCT FROM_LOOP #define BODY \ { \ @@ -266,6 +267,7 @@ internal_ucs4_loop (const unsigned char **inptrp, const unsigned char *inend, #define FUNCTION_NAME __gconv_transform_utf8_internal #define MIN_NEEDED_INPUT MIN_NEEDED_FROM +#define MAX_NEEDED_INPUT MAX_NEEDED_FROM #define MIN_NEEDED_OUTPUT MIN_NEEDED_TO #define LOOPFCT FROM_LOOP #define BODY \ @@ -278,69 +280,75 @@ internal_ucs4_loop (const unsigned char **inptrp, const unsigned char *inend, ch = *inptr; \ \ if (ch < 0x80) \ - /* One byte sequence. */ \ - cnt = 1; \ - else if ((ch & 0xe0) == 0xc0) \ { \ - cnt = 2; \ - ch &= 0x1f; \ - } \ - else if ((ch & 0xf0) == 0xe0) \ - { \ - /* We expect three bytes. */ \ - cnt = 3; \ - ch &= 0x0f; \ - } \ - else if ((ch & 0xf8) == 0xf0) \ - { \ - /* We expect four bytes. */ \ - cnt = 4; \ - ch &= 0x07; \ - } \ - else if ((ch & 0xfc) == 0xf8) \ - { \ - /* We expect five bytes. */ \ - cnt = 5; \ - ch &= 0x03; \ - } \ - else if ((ch & 0xfe) == 0xfc) \ - { \ - /* We expect six bytes. */ \ - cnt = 6; \ - ch &= 0x01; \ + /* One byte sequence. */ \ + cnt = 1; \ + ++inptr; \ } \ else \ { \ - /* This is an illegal encoding. */ \ - result = GCONV_ILLEGAL_INPUT; \ - break; \ - } \ - \ - if (NEED_LENGTH_TEST && inptr + cnt >= inend) \ - { \ - /* We don't have enough input. */ \ - result = GCONV_INCOMPLETE_INPUT; \ - break; \ - } \ - \ - /* Read the possible remaining bytes. */ \ - for (i = 1; i < cnt; ++i) \ - { \ - uint32_t byte = inptr[i]; \ - \ - if ((byte & 0xc0) != 0x80) \ + if ((ch & 0xe0) == 0xc0) \ + { \ + cnt = 2; \ + ch &= 0x1f; \ + } \ + else if ((ch & 0xf0) == 0xe0) \ + { \ + /* We expect three bytes. */ \ + cnt = 3; \ + ch &= 0x0f; \ + } \ + else if ((ch & 0xf8) == 0xf0) \ + { \ + /* We expect four bytes. */ \ + cnt = 4; \ + ch &= 0x07; \ + } \ + else if ((ch & 0xfc) == 0xf8) \ + { \ + /* We expect five bytes. */ \ + cnt = 5; \ + ch &= 0x03; \ + } \ + else if ((ch & 0xfe) == 0xfc) \ + { \ + /* We expect six bytes. */ \ + cnt = 6; \ + ch &= 0x01; \ + } \ + else \ { \ /* This is an illegal encoding. */ \ result = GCONV_ILLEGAL_INPUT; \ break; \ } \ \ - ch <<= 6; \ - ch |= byte & 0x3f; \ + if (NEED_LENGTH_TEST && inptr + cnt > inend) \ + { \ + /* We don't have enough input. */ \ + result = GCONV_INCOMPLETE_INPUT; \ + break; \ + } \ + \ + /* Read the possible remaining bytes. */ \ + for (i = 1; i < cnt; ++i) \ + { \ + uint32_t byte = inptr[i]; \ + \ + if ((byte & 0xc0) != 0x80) \ + { \ + /* This is an illegal encoding. */ \ + result = GCONV_ILLEGAL_INPUT; \ + break; \ + } \ + \ + ch <<= 6; \ + ch |= byte & 0x3f; \ + } \ + inptr += cnt; \ } \ \ /* Now adjust the pointers and store the result. */ \ - inptr += cnt; \ *((uint32_t *) outptr)++ = ch; \ } #include -- cgit v1.2.3
