* getopt: better handling of ambiguous optionsZack Weinberg2017-04-061-126/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | | | glibc's getopt uses alloca to construct a linked list of possibilities for an "ambiguous" long option. In gnulib, malloc should be used instead. Providing for both cases complicates things a fair bit. This patch rewrites ambiguous-option handling to use a boolean vector instead of a linked list. There is then only one allocation that might need freeing; in glibc it can honor __libc_use_alloca as usual, and in gnulib we define __libc_use_alloca to always be false, so we don't need ifdefs in the middle of the function. This should also be slightly more efficient in the normal case of long options being fully spelled out -- I think most people aren't even aware they _can_ sometimes abbreviate long options. One interesting consequence is that the list of possibilities is now printed in exactly the order they appear in the list of long options, instead of the first possibility being shuffled to the end. (The patch looks bigger than it really is because there's a fair bit of reindentation and code rearrangement.) * lib/getopt.c: When used standalone, define __libc_use_alloca as always false and alloca to abort if called. (process_long_option): Rewrite handling of ambiguous long options to use a single boolean vector, not a linked list; use __libc_use_alloca to decide whether to allocate this using alloca.
* getopt: refactor long-option handlingZack Weinberg2017-04-061-334/+204
| | | | | | | | | | | | | There were two copies of the bulk of the code to handle long options. Now there is only one. This change temporarily removes the logic to avoid using alloca when standalone; the next patch in the series will restore it. * lib/getopt.c (process_long_option): New function split out from _getopt_internal_r. (_getopt_internal_r): Replace both copies of the long-option processing code with calls to process_long_option.
* getopt: tidy up _getopt_initialize a bitZack Weinberg2017-04-061-12/+6
| | | | | | | | | | | | | | | | _getopt_data.__posixly_correct is completely redundant to _getopt_data.__ordering, and some work that logically belongs in _getopt_initialize was being done by _getopt_internal_r, making the code harder to understand. As a side effect, getenv will no longer be called if the first character of the options string is '+' or '-', which is probably a Good Thing. (Perhaps we should have a flag character that specifically asks for the permutation behavior?) * lib/getopt_int.h (_getopt_data): Remove __posixly_correct field. * lib/getopt.c (_getopt_internal_r): Move some initialization code... (_getopt_initialize): ...here. Don't set d->__posixly_correct.
* getopt: merge from glibc: repetition reductionZack Weinberg2017-04-061-26/+17
| | | | | | | | | | | | | | | The definitions of the entry point functions 'getopt' and '__posix_getopt' can be made substantially less repetitive with a helper macro. While I was merging the const-correctness changes from gnulib into glibc I noticed there are still some unnecessary casts in _getopt_internal_r. * lib/getopt.c (getopt, __posix_getopt): Eliminate repetition with a macro. Consistently cast 'argv' to 'char **' when calling _getopt_internal. (_getopt_internal_r): Remove unnecessary casts when calling exchange.
* getopt: clean up error reportingZack Weinberg2017-04-061-308/+53
| | | | | | | | | | | | | | | | | | | | | | | getopt can print a whole bunch of error messages, and when used standalone (from gnulib) it uses fprintf to do that. But fprintf is a cancellation point and getopt isn't, and also applying fprintf to a stream in wide-character mode is not allowed. So every single error reporting case has an #ifdef _LIBC block in which it calls internal libc functions instead. The counterpart patch series in glibc makes it possible to simplify all of that down to a set of #defines at the top of the file; core code is written as if it is safe to just call fprintf, flockfile, and funlockfile. (One caveat: it's *not* safe to call any *other* stdio functions.) * lib/getopt.c: When _LIBC is defined, define fprintf to __fxprintf_nocancel, flockfile to _IO_flockfile, and funlockfile to _IO_funlockfile. When neither _LIBC nor _POSIX_THREAD_SAFE_FUNCTIONS is defined, define flockfile and funlockfile as no-ops. (_getopt_internal_r): Remove all internal #ifdef _LIBC blocks; the standalone error-printing code can now be used for libc as well. Add an flockfile/funlockfile pair around one case where the error message is printed in several chunks. Don't use fputc.
* getopt: fix fencepost error in ambiguous-W-option handlingZack Weinberg2017-04-061-1/+0
| | | | | | | | | | | | | | | | | getopt_long contains an undocumented (AFAICT) feature in which, if you put "W;" in the short-options list, then '-W foo' and '-Wfoo' are treated as equivalent to '--foo'. This is implemented with a partial second copy of the code for handling long options, and that code increments optind one too many times when recovering from an ambiguous abbreviated option, which can cause the main loop to walk past the end of argv and crash. I discovered this while writing a test case that tries to exercise all of getopt's error reporting paths; I wouldn't be surprised to learn that this feature is never used by real applications. * lib/getopt.c (_getopt_internal_r): Don't increment d->optind a second time when reporting ambiguous -W options.
* getopt: clean up getopt.c and getopt1.c file headersZack Weinberg2017-04-061-9/+0
| | | | | | | | | | | | | | | | | | | In getopt.c, there is no need to include wchar.h at all, and it is safe nowadays to assume that stdlib.h does declare getenv (several other gnulib modules make this assumption). In getopt1.c, the #ifdef _LIBC block at the top can be simplified by using "" inclusions consistently, and there is no actual need to include stdlib.h (except in the #ifdef TEST block, where it should be unconditional), nor to provide a backup definition of NULL at all. * lib/getopt1.c: Simplify #ifdeffage at top of file. Move inclusion of stdlib.h to #ifdef TEST block and make unconditional. Do not define NULL. * lib/getopt.c: Don't include wchar.h. No need to declare getenv. * m4/getopt.m4 (gl_PREREQ_GETENV): Delete. * modules/getopt-gnu, modules/getopt-posix: Don't call gl_PREREQ_GETENV.
* getopt: harmonize comments with glibcZack Weinberg2017-04-061-12/+19
| | | | | | | | | The comments explaining how the behavior of 'getopt' varies depending on whether it's the standalone version and whether there are special characters at the beginning of the options string were inconsistent between gnulib and glibc, and also out of sync with the code. * lib/getopt.c, lib/getopt_int.h: Harmonize comments with glibc.
* getopt: remove USE_NONOPTION_FLAGSZack Weinberg2017-04-061-95/+2
| | | | | | | | | | | | | | | | | | | | | | | getopt includes code to parse an environment variable named _XXX_GNU_nonoption_argv_flags_ (where XXX is the current process's PID in decimal); but all of it has been #ifdefed out since 2001, with no official way to turn it back on. According to commentary in glibc's config.h.in, bash version 2.0 set this environment variable to indicate argv elements that were the result of glob expansion and therefore should not be treated as options, but the feature was "disabled later" because "it caused problems". According to bash's CHANGES file, "later" was release 2.01; it gives no more detail about what the problems were. Version 2.0 of bash was released on the last day of 1996, and version 2.01 in June of 1997. Twenty years later, I think it is safe to assume that this environment variable isn't coming back. * lib/getopt_int.h: Remove all #ifdef USE_NONOPTION_FLAGS blocks. * lib/getopt.c: Likewise. Also remove SWAP_FLAGS and the __libc_argc and __libc_argv externs, which were only used by
* getopt: tabify, in preparation for merge with glibcZack Weinberg2017-04-061-668/+668
| | | | | | | | | | glibc sticks to the GNU default of indenting with a mix of 8-column tabs and spaces; make the gnulib copy match. getopt.h is not included because it is *not* going to be merged in its present form. * getopt.c, getopt1.c, getopt_int.h: Tabify.
* getopt: merge from glibcPaul Eggert2017-03-221-35/+35

Reported by Dagobert Michelson, via Joel E. Denny. Signed-off-by: Eric Blake <eblake@redhat.com>

* gnulib-common: prefer _GL_UNUSED over _UNUSED_PARAMETER_Eric Blake2009-12-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are more contexts where __attribute__((__unused__)) is useful than just parameter lists. Also, naming the macro _GL_UNUSED fits with the recent addition of _GL_ARG_NONNULL.
