| * Fixes for pty handling in gdb-mi.el and process.c.Chong Yidong2012-04-201-10/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisp/progmodes/gdb-mi.el (gdb): Revert 2012-04-19 change. (gdb-inferior-io--init-proc): New function. (gdb-init-1): Use it. (gdb-inferior-io-sentinel): New sentinel for the gdb-inferior pty, responsible for allocating a new pty and hooking it to gdb when the old pty gets an EIO due to process exit. (gdb-delchar-or-quit): New command. Bind it in gdb-mi buffers. (gdb-tooltip-print): Don't use obsolete tooltip-use-echo-area. (gdb-inferior-io--maybe-delete-pty): Move into gdb-reset. * src/process.c (wait_reading_process_output): If EIO occurs on a pty, set the status to "failed" and ensure that sentinel is run. * doc/lispref/processes.texi (Asynchronous Processes): Mention nil argument to start-process.

(emacs_gnutls_read): Use new log functions, `gnutls_handshakes_tried' process member, and `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake attempts per process (connection). * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.

* | configure: new option --enable-gcc-warningsPaul Eggert2012-04-091-0/+7
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have been using this change for many months in my private copy of Emacs, and have used it to find several bugs. It's mature enough to publish now. * Makefile.in (GNULIB_MODULES): Add warnings, manywarnings. * configure.in: Support --enable-gcc-warnings, in the style of other GNU packages such as coreutils. (C_WARNINGS_SWITCH): Remove, replacing with... (WARN_CFLAGS, GNULIB_WARN_CFLAGS): New variable. (PKG_CHECK_MODULES, C_SWITCH_X_SITE): Use -isystem rather than -I, when including system files with GCC. * etc/NEWS: Mention --enable-gcc-warnings. * lib/Makefile.am (AM_CFLAGS): New macro. * m4/manywarnings.m4, m4/warnings.m4: New files, from gnulib. * lib-src/Makefile.in (C_WARNINGS_SWITCH): Remove.

(ALL_CFLAGS): Use new macros rather than old. * src/process.c: Ignore -Wstrict-overflow to work around GCC bug 52904. * src/regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore -Wunused-but-set-variable, -Wunused-function, -Wunused-macros, -Wunused-result, -Wunused-variable. This should go away once the Emacs and Gnulib regex code is merged. (xmalloc, xrealloc): Now static.

Check for sa_len in struct ifreq.ifr_addr (Bug#8477). * src/process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477). (Fnetwork_interface_list): Allocate in increments of bytes instead of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct sockaddr. (struct ifflag_def): notrailers is smart on OSX. (Fnetwork_interface_info): Handle case when ifr_flags is negative. Get hardware address with getifaddrs if available.

* Variadic C functions now count arguments with ptrdiff_t.Paul Eggert2011-06-141-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | This partly undoes my 2011-03-30 change, which replaced int with size_t. Back then I didn't know that the Emacs coding style prefers signed int. Also, in the meantime I found a few more instances where arguments were being counted with int, which may truncate counts on 64-bit machines, or EMACS_INT, which may be unnecessarily wide. * lisp.h (struct Lisp_Subr.function.aMANY) (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Arg counts are now ptrdiff_t, not size_t. All variadic functions and their callers changed accordingly. (struct gcpro.nvars): Now size_t, not size_t. All uses changed. * bytecode.c (exec_byte_code): Check maxdepth for overflow, to avoid potential buffer overrun. Don't assume arg counts fit in 'int'. * callint.c (Fcall_interactively): Check arg count for overflow, to avoid potential buffer overrun. Use signed char, not 'int', for 'varies' array, so that we needn't bother to check its size calculation for overflow. * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args. * eval.c (apply_lambda): * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length. (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed. (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
