Instead of adding a new lib/xstrtoumax.h I thought + it cleaner to put all the xstroto* declarations into a single + header, which for now is lib/xstrtol.h for lack of a better place. + (Mayby lib/xstdlib.h would be better? :-) + + I thought of several other problems with shredding regular files; + shredding devices is much more reliable. So I changed the defaults + to be more suitable for shredding devices; this should help encourage + users to do the right thing. + + pfstatus isn't portable to environments with varying width + fonts, or with internationalized environments where the byte + count of the message is not the same as its print width. + Rather than deal with this, I just simplified it to not do + tricks with carriage-returns and spaces. (I'm also worried + that vprintf may not return the right value on some hosts; I + vaguelly recall this being a problem.) As a result, -v and - + no longer conflict. + + When removing a special file, try to truncate it first, but don't + worry if this reports an error. + + Try to find the size of a non-regular file by seeking to its end. + + Various porting fixes, mostly because of a port to SunOS 4.1.4 cc. + + Some other minor bug fixes. + + * lib/xstrtoul.h: Remove this file. + * lib/xstrtoumax.c: New file. + + * configure.in (AC_CHECK_FUNCS): Add strtoull, strtoumax, strtouq. + + * lib/xstrtoul.c (STRING_TO_UNSIGNED): Remove. + (__strtol, __strtol_t, __xstrtol): New macros. + + * lib/xstrtol.c (__strtol, __strtol_t, __xstrtol): + New macros to specify the + underlying function, its returned type, and our function. Default to + values suitable for xstrtol. + + Include <ctype.h>, since we use its macros. + + (ULONG_MAX, LONG_MAX, ISBLANK): Remove: no longer needed. + (ISSPACE): New macro. + + (bkm_scale, bkm_scale_by_power, __xstrtol, main): __unsigned long int + -> __strtol_t. + + (__xstrtol): Depend on whether __strtol_t is an unsigned type, not on + whether STRING_TO_UNSIGNED is defined. Skip isspace chars, not + isblank chars, to match strtol. When returning + LONGINT_INVALID_SUFFIX_CHAR, store the value that we computed into + *val. + + * lib/xstrtol.h (__xstrtol, __strtol, __unsigned): Remove macro decls. + <inttypes.h>: Include if HAVE_INTTYPES_H. + (_DECLARE_XSTRTOL): New macro. + (xstrtol, xstrtoul, xstrtoumax): Declare all three functions, so that + we need only one include file, not three. + (_STRTOL_ERROR): Do not undef, as this is no longer needed. + Reword overflow message so that it's independent of type. + + * lib/Makefile.am (libfu_a_SOURCES): Add xstrtoumax.c. + (noinst_HEADERS): Remove xstrtoul.h. + + * lib/xmalloc.c (xalloc_fail): + Pass xalloc_msg_memory_exhausted through gettext. + + * lib/getdate.y: + <stdlib.h>: Include if HAVE_STDLIB_H, since bison 1.27 invokes "free". + (LookupWord, yylex): Don't pass negative char to ctype macros. + + * doc/fileutils.texi: + Explain why shredding devices is more reliable, and why the + default options are more suitable for devices. + + Remove withdrawn options -b or --no-contents, -c or --freed-contents, + -C or --all-contents, -k or --no-links, -l or --ordinary-links, -L or + --all-links. + + Add -R or --remove, -s or --size. + + -v can no longer be doubled. + + `file system' --> `filesystem' uniformly. + + * src/chgrp.c: Include xstrtol.h, not obsolete file xstrtoul.h. + + * src/shred.c: Include xstrtol.h, not obsolete file xstrtoul.h. + "human.h", "xalloc.h": Include. + (attribute): Remove; no longer needed. + (xstrdup): New decl. + (STDOUT_FILENO): New macro. + (O_NOCTTY): Make sure it's always defined, even if HAVE_CONFIG_H. + + The following changes have effect only if !HAVE_CONFIG_H. + <ctype.h>: New include. + (RETSIGTYPE): Remove bogus semicolon at end. + (STDOUT_FILENO, uintmax_t, human_readable, LONGEST_HUMAN_READABLE): + New macros. + (xstrtoumax): Renamed from xstrtoul, with corresponding type changes. + Handle suffixes like the real routine does. + (error): Remove bogus assignment of errno to errnum. + (xmalloc, xstrdup): New functions. + + (O_NOCTTY): Define even if !HAVE_CONFIG_H. + (S_ISFIFO, S_ISSOCK): New macros, if not already defined. + (OUTPUT_BLOCK_SIZE): New macro. + (struct Options.verbose): Now a boolean, since we no longer have two + levels of verbosity. + (long_opts, usage, main): Remove -D or --device option. Invert -p or + --preserve option, and rename it to -R or --remove. + (usage): Describe G suffix. + (usage): "-" no longer conflicts with -v. + (UCHAR_MAX): Indent `#error' so that SunOS 4.1.4 cc doesn't reject it. + (ind): Portability fixes: return word32, not unsigned; multiply by + sizeof (word32) instead of shifting left by 2. + (isaac_refill, isaac_mix): Comment out size of array parameter, as + ansi2knr mishandles this. + (status_visible, status_pos, pfstatus, flushstatus): Remove, since + pfstatus isn't portable to users with varying width fonts, or + internationalized messages, and vfprintf is problematic. All callers + of pfstatus changed to use error instead; this removes incompatibility + of -v with -. All calls to flushstatus removed. + (dopass, do_wipefd): Do not translate non-English msgs with gettext. + + (dopass): Cast lseek constant arguments to (off_t) for benefit + of pre-ANSI compilers; fix one lseek call whose args were interchanged. + Remove unnecessary casts to (off_t). Do not check for EIO + when determining file size; this was just my earlier wild guess. + Use human_readable to print off_t, instead of casting to unsigned long + (which doesn't work in Solaris 2.6, where off_t is longer than long). + Output human-readable sizes, instead of always using "K". + Check for offset overflow (it happened to me in SunOS 4.1.4). + (do_wipefd): Do not insist on regular files, but do check for special + files that cannot possibly be shredded. + Use xmalloc instead of malloc + check. + Do not inspect st_size for non-regular files. + Try to find the size of a non-regular file by seeking to its end. + Do not assume that a regular file of size-0 has unknown size. + Check for regular files with negative sizes, + and for overflow after rounding to next block. + Always try to truncate, even for special files, but do not report an + error if truncation fails on a special file. + + (dopass, wipefile): Do not return 1 for special files; the caller + doesn't care any more. + + (wipefd): Remove unnecessary (and nonportable) check for + whether the file descriptor is read-only. Remove + no-longer-needed check for `-v -'. + + (incname): Return 1 for carry bit, like the documentation says. + + (wipename, wipefile): Accept new argument, specifying the + quoted file name. All callers changed. + + (wipename): Use xstrdup instead of strdup+error check. + + (wipefile): Check for ENOTDIR when opening /dev/fd/NNN. Check for + errors in NNN more carefully. Restore errno after the check. + Check for errors when closing the file descriptor. + Use more consistent wording when unable to remove a file. + + (main): Do not remove files by default. + Use xstrtoumax instead of xstrtoul uniformly, since xstrtoul won't + exist if !HAVE_CONFIG_H. + In diagnostics, quote invalid operands to -n and -s options. + Allow T, P, E, Z, and Y suffixes in -s operand. + flags.verbose is now a boolean, not a counter. + Use STDOUT_FILENO instead of 1, for clarity. + + * lib/human.c: + Include xstrtol.h, not xstrtoul.h, since xstrtol.h now defines all the + xstrto... functions. + + * src/dd.c: Include xstrtol.h. + (parse_integer): Migrate most of the work into the new xstrtoumax fn. + + * lib/xstrtoumax.c: New file. + 1999-04-18 Jim Meyering <meyering@ascend.com> * src/dd.c (main): Open the output file with *read* access |
