update doc regarding Solaris 11
About a month ago, Solaris 11 Express was released. It's something like a beta of Solaris 11 that is scheduled to be released in 2011. It's the successor (from the Oracle side) of the OpenSolaris project; maybe we'll also have to consider Illumos / OpenIndiana in the future. I'm updating the documentation, replacing many mentions of "Solaris 10" by "Solaris 11 2010-11". 2010-12-04 Bruno Haible Update for Solaris 11 2010-11. * doc/{glibc,posix}-{functions,headers}: Add info about Solaris 11 Express, released in November 2010. More important than the changes are the places that have not changed, that is, the bugs which have been fixed and the functions which have been added, compared to Solaris 10. New POSIX functions: dirfd faccessat fchmodat futimens getdelim getline linkat mkdirat mkdtemp mkfifoat mknodat posix_fadvise posix_fallocate posix_madvise posix_memalign pthread_mutexattr_getrobust pthread_mutexattr_setrobust pthread_mutex_consistent readlinkat stpcpy stpncpy strndup strnlen symlinkat utimensat wcpcpy wcpncpy wcscasecmp wcsdup wcsncasecmp wcsnlen New glibc compatible functions and variables: advance asprintf backtrace_symbols_fd backtrace_symbols backtrace canonicalize_file_name cbc_crypt clearenv dl_iterate_phdr ecb_crypt err errx fcloseall ffsll ffsl freeifaddrs getifaddrs getipv4sourcefilter get_nprocs_conf get_nprocs getsourcefilter inet_neta loc1 loc2 locs memmem mkstemps setipv4sourcefilter setsourcefilter step strcasestr strchrnul strsep vasprintf verr verrx vwarn vwarnx warn warnx New features: now supports also the 2002 revision of GNU .mo files. Bug fixes: now defines ssize_t. now defines NAN and HUGE_VAL to usable values. getopt_long and getopt_long_only support the '+' flag. The *printf functions support precisions larger than 512. iconv() now reports failures. realpath() actually works now. strcoll() in UTF-8 locales is fixed. Bruno

I'm talking about programs run through AC_RUN_IFELSE, not about the contents of TESTS in Automake. > Similarly aegis and > projects using it regard 0 as "pass", 1 as "fail" and anything else as > "indeterminate". This is not a problem: aegis cannot look at the return values of programs that come from gnulib *.m4 files, and vice versa. Bruno

One other thing to be careful of with bit masks. If the particular combination of failures matches 63, 77, or 99 (as commonly used by automake and autoconf to mean version mismatch, skip, or hard fail), then the configure script might misbehave. Enumerated failures, while only providing the first failure rather than a combination of failures, are less likely to get that high. > > Here's the proposed patch.

Thanks for tackling this. I haven't looked closely at it yet, but given your testing, it's probably won't need much further tweaking. -- Eric Blake ebl...@redhat.com+1-801-349-2682 Libvirt virtualization library http://libvirt.org signature.asc Description: OpenPGP digital signature

Oh yes, I see what you mean now. I think this must be an argp bug. The struct argp_option entries just look like this: { "no-hyphenation", OPT_NO_HYPHENATION,0, 0, N_("turn off hyphenation") }, { "nh", 0, 0, OPTION_ALIAS }, { "no-justification", OPT_NO_JUSTIFICATION,0, 0, N_("turn off justification") }, { "nj", 0, 0, OPTION_ALIAS }, So I think argp-help's wrapping is buggy. I could look into that, but it's a couple of thousand lines of code I don't know at all right now - perhaps somebody on bug-gnulib can help? > That it may not be a joke is suggested by some similar oddness in the > documentation of -p, where there is an apparently unintended line > break just before "g - grap" (from the formatting of the rest of the > test, one would expect it afterwards, and then for "r - refer" to be > indented up to the same column as the preceding line, which starts "e > - [n]eqn". That's a different issue. I deliberately inserted a \n there because I didn't want to deal with line-wrapping in the middle of something that's supposed to look like this: -p, --preprocessor=STRING STRING indicates which preprocessors to run: e - [n]eqn, p - pic, t - tbl, g - grap, r - refer, v - vgrind However, instead it comes out looking like this: -p, --preprocessor=STRING STRING indicates which preprocessors to run: e - [n]eqn, p - pic, t - tbl, g - grap, r - refer, v - vgrind Shouldn't argp put a sensible left margin after each newline?

Hi Eric, > If the particular > combination of failures matches 63, 77, or 99 (as commonly used by > automake and autoconf to mean version mismatch, skip, or hard fail), > then the configure script might misbehave. In the generated configure scripts, AC_RUN_IFELSE tests for an exit code equal to 0 and nothing else. And this cannot change, because it's documented behaviour of AC_RUN_IFELSE: -- Macro: AC_RUN_IFELSE (INPUT, [ACTION-IF-TRUE], [ACTION-IF-FALSE], [ACTION-IF-CROSS-COMPILING]) If PROGRAM compiles and links successfully and returns an exit status of 0 when executed, run shell commands ACTION-IF-TRUE. Otherwise, run shell commands ACTION-IF-FALSE. So, there is no problem now, and there cannot be a problem in the future. Bruno
