* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-131-1/+1
| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.

It was reported by Chris Torek in 1983 even before GNU Emacs existed, which must set some sort of record. (Torek's bug report was against a predecessor of GNU Emacs, but GNU Emacs happened to have the same common flaw.) See Torek's Usenet posting "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858 Posted: Fri Apr 8 14:18:56 1983. * .bzrignore: Add lib/fcntl.h. * configure.ac (euidaccess): Remove check; gnulib does this for us now. (gl_FCNTL_O_FLAGS): Define a dummy version. * lib/at-func.c, lib/euidaccess.c, lib/faccessat.c, lib/fcntl.in.h: * lib/getgroups.c, lib/group-member.c, lib/root-uid.h: * lib/xalloc-oversized.h, m4/euidaccess.m4, m4/faccessat.m4: * m4/fcntl_h.m4, m4/getgroups.m4, m4/group-member.m4: New files, from gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * admin/merge-gnulib (GNULIB_MODULES): Add faccessat. (GNULIB_TOOL_FLAGS): Avoid at-internal, fchdir, malloc-posix, openat-die, openat-h, save-cwd. Do not avoid fcntl-h. Omit gnulib's m4/fcntl-o.m4. * nt/inc/ms-w32.h (AT_FDCWD, AT_EACCESS): New symbols. (access): Remove. (faccessat): New macro. * src/Makefile.in (LIB_EACCESS): New macro. (LIBES): Use it. * src/callproc.c (init_callproc): * src/charset.c (init_charset): * src/fileio.c (check_existing, check_executable, check_writable) (Ffile_readable_p): * src/lread.c (openp, load_path_check): * src/process.c (allocate_pty): * src/xrdb.c (file_p): Use effective UID when checking permissions, not real UID. * src/callproc.c (init_callproc): * src/charset.c (init_charset): * src/lread.c (load_path_check, init_lread): Test whether directories are accessible, not merely whether they exist. * src/conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro. * src/fileio.c (check_existing, check_executable, check_writable) (Ffile_readable_p): Use symbolic names instead of integers for the flags, as they're portable now. (check_writable): New arg AMODE. All uses changed. Set errno on failure. (Ffile_readable_p): Use faccessat, not stat + open + close. (Ffile_writable_p): No need to call check_existing + check_writable. Just call check_writable and then look at errno. This saves a syscall. dir should never be nil; replace an unnecessary runtime check with an eassert. When checking the parent directory of a nonexistent file, check that the directory is searchable as well as writable, as we can't create files in unsearchable directories. (file_directory_p): New function, which uses 'stat' on most platforms but faccessat with D_OK (for efficiency) if WINDOWSNT. (Ffile_directory_p, Fset_file_times): Use it. (file_accessible_directory_p): New function, which uses a single syscall for efficiency. (Ffile_accessible_directory_p): Use it. * src/xrdb.c (file_p): Use file_directory_p. * src/lisp.h (file_directory_p, file_accessible_directory_p): New decls. * src/lread.c (openp): When opening a file, use fstat rather than stat, as that avoids a permissions race. When not opening a file, use file_directory_p rather than stat. (dir_warning): First arg is now a usage string, not a format. Use errno. All uses changed. * src/nsterm.m (ns_term_init): Remove unnecessary call to file-readable that merely introduced a race. * src/process.c, src/sysdep.c, src/term.c: All uses of '#ifdef O_NONBLOCK' changed to '#if O_NONBLOCK', to accommodate gnulib O_* style, and similarly for the other O_* flags. * src/w32.c (sys_faccessat): Rename from sys_access and switch to faccessat's API. All uses changed. * src/xrdb.c: Do not include <sys/stat.h>; no longer needed. (magic_db): Rename from magic_file_p. (magic_db, search_magic_path): Return an XrmDatabase rather than a char *, so that we don't have to test for file existence separately from opening the file for reading. This removes a race fixes a permission-checking problem, and simplifies the code. All uses changed. (file_p): Remove; no longer needed. Fixes: debbugs:12632
* * editfns.c (get_system_name): Remove.Dmitry Antipov2012-10-161-8/+4
| | | | | | * lisp.h (get_system_name): Remove prototype. * xrdb.c (getenv, getpwuid, getpwnam): Remove prototypes. (get_environ_db): Use Vsystem_name. Avoid call to strlen.
* Port better to POSIX hosts lacking _setjmp.Paul Eggert2012-09-151-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | * configure.ac (HAVE__SETJMP, HAVE_SIGSETJMP): New symbols. (_setjmp, _longjmp): Remove. * src/lisp.h: Include <setjmp.h> here, since we use its symbols here. All instances of '#include <setjmp.h>' removed, if the only reason for the instance was because "lisp.h" was included. (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols. Unless otherwise specified, replace all uses of jmp_buf, _setjmp, and _longjmp with the new symbols. Emacs already uses _setjmp if available, so this change affects only POSIXish hosts that have sigsetjmp but not _setjmp, such as some versions of Solaris and Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.) * src/image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros. (png_load_body) [HAVE_PNG]: (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]: (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]: Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp, since PNG requires jmp_buf. This is the only exception to the general rule that we now use sys_setjmp and sys_longjmp. This exception is OK since this code does not change the signal mask or longjmp out of a signal handler. Fixes: debbugs:12446
