Prepare for gnulib update After the last gnulib import (Dec 2012), gnulib upstream started replacing mingw's 'struct timeval' with a version with 64-bit time_t, for POSIX compliance: commit f8e84098084b3b53bc6943a5542af1f607ffd477 Author: Bruno Haible <bruno@clisp.org> Date: Sat Jan 28 18:12:10 2012 +0100 sys_time: Override 'struct timeval' on some native Windows platforms. See: https://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00372.html However, that results in conflicts with native Winsock2's 'select': select()'s argument http://sourceforge.net/p/mingw-w64/mailman/message/29610438/ ... and libiberty's timeval-utils.h timeval_add/timeval_sub, at the least. We don't really need the POSIX compliance, so this patch prepares us to simply not use gnulib's 'struct timeval' replacement once a more recent gnulib is imported, thus preserving the current behavior, by adding a sys/time.h wrapper header that undefs gnulib's replacements, and including that everywhere instead. The SIZE -> OSIZE change is necessary because newer gnulib's sys/time.h also includes windows.h/winsock2.h, which defines a conflicting SIZE symbol. Cross build-tested mingw-w64 32-bit and 64-bit. Regtested on x86_64 Fedora 20. gdb/ChangeLog: 2015-08-24 Pedro Alves <palves@redhat.com> * Makefile.in (HFILES_NO_SRCDIR): Add common/gdb_sys_time.h. * common/gdb_sys_time.h: New file. * event-loop.c: Include gdb_sys_time.h instead of sys/time.h. * gdb_select.h: Likewise. * gdb_usleep.c: Likewise. * maint.c: Likewise. * mi/mi-main.c: Likewise. * mi/mi-parse.h: Likewise. * remote-fileio.c: Likewise. * remote-m32r-sdi.c: Likewise. * remote.c: Likewise. * ser-base.c: Likewise. * ser-pipe.c: Likewise. * ser-tcp.c: Likewise. * ser-unix.c: Likewise. * symfile.c: Likewise. * symfile.c: Likewise.

Import "glob" and "getcwd" modules from gnulib These two modules are necessary because of the rework that will be done in the "change directory" logic on GDB/gdbserver in the next commits. First, we will get rid of the "gdb_dirbuf" global variable and instead rely on the fact that "getcwd (NULL, 0)", which is a GNU extension, returns a heap-allocated string with the necessary bytes to hold the full path. This is a good practice not only because globals are not ideal but also because there is no good way to know beforehand the size of the full pathname allowed in the filesystem ("PATH_MAX" is not portable and does not reflect all the possible filesystems out there). We will also have a way to "cd" to a directory also on gdbserver, but in order to do that uniformly, there must be a way to do tilde expansion on directories provided by the user. Currently, GDB uses "tilde_expand" from readline to do that, but gdbserver doesn't link against readline and therefore cannot use this function. The solution is to use "glob" instead, which can perform tilde expansion as a GNU extension. Therefore, we need gnulib's version of "glob". A special note is necessary for gdb/ser-tcp.c. It defines "close" as "closesocket" on Win32 targets. If we leave the code as is, this would conflict with gnulib's definition of "close". Therefore, in order to keep the same code path from before this import, I decided to "#undef close" first, and then let the original (re)definition of it take place. gdb/ChangeLog: 2017-09-22 Sergio Durigan Junior <sergiodj@redhat.com> * gnulib/aclocal.m4: Regenerate. * gnulib/config.in: Regenerate. * gnulib/configure: Regenerate. * gnulib/import/Makefile.am: Regenerate. * gnulib/import/Makefile.in: Regenerate. * gnulib/import/assure.h: New file. * gnulib/import/at-func.c: Likewise * gnulib/import/chdir-long.c: New file. * gnulib/import/chdir-long.h: New file. * gnulib/import/cloexec.c: New file. * gnulib/import/cloexec.h: New file. * gnulib/import/close.c: New file. * gnulib/import/closedir.c: New file. * gnulib/import/dirent-private.h: New file. * gnulib/import/dup-safer.c: New file. * gnulib/import/dup.c: New file. * gnulib/import/dup2.c: New file. * gnulib/import/error.c: New file. * gnulib/import/error.h: New file. * gnulib/import/exitfail.c: New file. * gnulib/import/exitfail.h: New file. * gnulib/import/fchdir.c: New file. * gnulib/import/fcntl.c: New file. * gnulib/import/fcntl.in.h: New file. * gnulib/import/fd-hook.c: New file. * gnulib/import/fd-hook.h: New file. * gnulib/import/fd-safer.c: New file. * gnulib/import/fdopendir.c: New file. * gnulib/import/filename.h: New file. * gnulib/import/filenamecat-lgpl.c: New file. * gnulib/import/filenamecat.h: New file. * gnulib/import/fstat.c: New file. * gnulib/import/fstatat.c: New file. * gnulib/import/getcwd-lgpl.c: New file. * gnulib/import/getcwd.c: New file. * gnulib/import/getdtablesize.c: New file. * gnulib/import/getlogin_r.c: New file. * gnulib/import/getprogname.c: New file. * gnulib/import/getprogname.h: New file. * gnulib/import/gettext.h: New file. * gnulib/import/glob-libc.h: New file. * gnulib/import/glob.c: New file. * gnulib/import/glob.in.h: New file. * gnulib/import/intprops.h: New file. * gnulib/import/m4/chdir-long.m4: New file. * gnulib/import/m4/close.m4: New file. * gnulib/import/m4/closedir.m4: New file. * gnulib/import/m4/d-ino.m4: New file. * gnulib/import/m4/d-type.m4: New file. * gnulib/import/m4/dup.m4: New file. * gnulib/import/m4/dup2.m4: New file. * gnulib/import/m4/error.m4: New file. * gnulib/import/m4/fchdir.m4: New file. * gnulib/import/m4/fcntl.m4: New file. * gnulib/import/m4/fcntl_h.m4: New file. * gnulib/import/m4/fdopendir.m4: New file. * gnulib/import/m4/filenamecat.m4: New file. * gnulib/import/m4/fstat.m4: New file. * gnulib/import/m4/fstatat.m4: New file. * gnulib/import/m4/getcwd-abort-bug.m4: New file. * gnulib/import/m4/getcwd-path-max.m4: New file. * gnulib/import/m4/getcwd.m4: New file. * gnulib/import/m4/getdtablesize.m4: New file. * gnulib/import/m4/getlogin_r.m4: New file. * gnulib/import/m4/getprogname.m4: New file. * gnulib/import/m4/glob.m4: New file. * gnulib/import/m4/gnulib-cache.m4: Regenerate. * gnulib/import/m4/gnulib-comp.m4: Regenerate. * gnulib/import/m4/mempcpy.m4: New file. * gnulib/import/m4/memrchr.m4: New file. * gnulib/import/m4/mode_t.m4: New file. * gnulib/import/m4/msvc-inval.m4: New file. * gnulib/import/m4/msvc-nothrow.m4: New file. * gnulib/import/m4/open.m4: New file. * gnulib/import/m4/openat.m4: New file. * gnulib/import/m4/opendir.m4: New file. * gnulib/import/m4/readdir.m4: New file. * gnulib/import/m4/realloc.m4: New file. * gnulib/import/m4/rewinddir.m4: New file. * gnulib/import/m4/save-cwd.m4: New file. * gnulib/import/m4/strdup.m4: New file. * gnulib/import/m4/strerror.m4: New file. * gnulib/import/m4/unistd-safer.m4: New file. * gnulib/import/mempcpy.c: New file. * gnulib/import/memrchr.c: New file. * gnulib/import/msvc-inval.c: New file. * gnulib/import/msvc-inval.h: New file. * gnulib/import/msvc-nothrow.c: New file. * gnulib/import/msvc-nothrow.h: New file. * gnulib/import/open.c: New file. * gnulib/import/openat-die.c: New file. * gnulib/import/openat-priv.h: New file. * gnulib/import/openat-proc.c: New file. * gnulib/import/openat.c: New file. * gnulib/import/openat.h: New file. * gnulib/import/opendir.c: New file. * gnulib/import/pipe-safer.c: New file. * gnulib/import/readdir.c: New file. * gnulib/import/realloc.c: New file. * gnulib/import/rewinddir.c: New file. * gnulib/import/save-cwd.c: New file. * gnulib/import/save-cwd.h: New file. * gnulib/import/strdup.c: New file. * gnulib/import/strerror-override.c: New file. * gnulib/import/strerror-override.h: New file. * gnulib/import/strerror.c: New file. * gnulib/import/unistd--.h: New file. * gnulib/import/unistd-safer.h: New file. * gnulib/update-gnulib.sh (IMPORTED_GNULIB_MODULES): Add "getcwd" and "glob". * ser-tcp.c: Undefine "close" before redefining it.

Constify add_prefix_cmd This changes add_prefix_cmd to accept a const-taking function as an argument; then fixes up all the callers. In a couple of spots I had to add a non-const overload of a function, because the function is passed to two different command-adding "constructors". These overloads are temporary; once constification is complete they can be removed. This patch also fixes a typo I happened to notice while constifying. Note that this touches a couple of files (gnu-nat.c and go32-nat.c) that I can't build. So, while I made a best-effort there, I am not certain they will still compile.

Accept "set foo unlimited" in integer/uinteger/zuinteger_unlimited commands. Currently, several commands take "0" or "-1" to mean "unlimited". "show" knows when to print "unlimited": (gdb) show height Number of lines gdb thinks are in a page is 45. (gdb) set height 0 (gdb) show height Number of lines gdb thinks are in a page is unlimited. However, the user can't herself specify "unlimited" directly: (gdb) set height unlimited No symbol table is loaded. Use the "file" command. (gdb) This patch addresses that, by adjusting the set handler for all integer/uinteger/zuinteger_unlimited commands to accept literal "unlimited". It also installs a completer. Presently, we complete on symbols by default, and at <http://sourceware.org/ml/gdb-patches/2013-03/msg00864.html> I've shown a WIP prototype that tried to keep that half working in these commands. In the end, it turned out to be more complicated than justifiable, IMO. It's super rare to want to pass the value of a variable/symbol in the program to a GDB set/show knob. That'll still work, it's just that we won't assist with completion anymore. This patch just sticks with the simple, and completes on "unlimited", and nothing else. This simplification means that "set he<tab><tab>" is all it takes to get to: "set height unlimited" The patch then goes through all integer/uinteger/zuinteger_unlimited commands in the tree, and updates both the online help and the manual to mention that "unlimited" is accepted in addition to 0/-1. In the cases where the command had no online help text at all, this adds it. I've tried to make the texts read in a way that "unlimited" is suggested before "0" or "-1" is.
