* Improve integer range checkingPaul Eggert2020-04-051-9/+4
| | | | | | | | | | | | | | | | | | * src/bignum.c (check_integer_range, check_uinteger_max) (check_int_nonnegative): New functions. * src/frame.c (check_frame_pixels): New function. (Fset_frame_height, Fset_frame_width, Fset_frame_size): Use it. * src/lisp.h (CHECK_RANGED_INTEGER, CHECK_TYPE_RANGED_INTEGER): Remove these macros. Unless otherwise specified, all callers replaced by calls to check_integer_range, check_uinteger_range, check_int_nonnegative. * src/frame.c (gui_set_right_divider_width) (gui_set_bottom_divider_width): * src/nsfns.m (ns_set_internal_border_width): * src/xfns.c (x_set_internal_border_width): Using check_int_nonnegative means these functions no longer incorrectly reject negative bignums; they treat them as 0, just like negative fixnums.
* Make make-{network,serial}-process handle :coding nil consistentlyRobert Pluim2020-04-031-10/+6
| | | | | | | | | | | | | | | | | | The handling of :coding nil was different between make-{network,serial}-process and make-{pipe}process. Now they all handle :coding nil as if :coding had not been specified. * process.c (Fmake_serial_process) (set_network_socket_coding_system): Use plist-get to check if :coding has been specified instead of plist-member, to ensure that ":coding nil" does not override coding-system-for-{read,write}. * network-stream-tests.el (check-network-process-coding-system-bind) (check-network-process-coding-system-no-override) (check-network-process-coding-system-override): New tests. * etc/NEWS: Describe change in make-network-process and make-serial-process :coding behavior.
* Add a module function to open a file descriptor connected to a pipe.Philipp Stephani2020-03-261-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A common complaint about the module API is that modules can't communicate asynchronously with Emacs. While it isn't possible to call arbitrary Emacs functions asynchronously, writing to a pipe should always be fine and is a pretty low-hanging fruit. This patch implements a function that adapts an existing pipe process. That way, users can use familiar tools like process filters or 'accept-process-output'. * src/module-env-28.h: Add 'open_channel' module function. * src/emacs-module.c (module_open_channel): Provide definition for 'open_channel'. (initialize_environment): Use it. * src/process.c (open_channel_for_module): New helper function. (syms_of_process): Define necessary symbol. * test/src/emacs-module-tests.el (module/async-pipe): New unit test. * test/data/emacs-module/mod-test.c (signal_system_error): New helper function. (signal_errno): Use it. (write_to_pipe): New function running in the background. (Fmod_test_async_pipe): New test module function. (emacs_module_init): Export it. * doc/lispref/internals.texi (Module Misc): Document new module function. * doc/lispref/processes.texi (Asynchronous Processes): New anchor for pipe processes. * etc/NEWS: Document 'open_channel' function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Bug#38218 * src/process.c (Fnetwork_interface_list): Extend argument list to allow requesting full network info and/or IPv4/IPv6 info. (network_interface_list) [HAVE_GETIFADDRS]: Use getifaddrs to retrieve interface IP addresses. * src/process.h: Update prototype of network_interface_list. * src/w32.c (g_b_init_get_adapters_addresses): New init flag. (globals_of_w32): Initialize it. (GetAdaptersAddresses_Proc): New function typedef. (get_adapters_addresses): New wrapper function. (init_winsock): Load htonl and ntohl. (sys_htonl, sys_ntohl): New wrapper functions. (network_interface_list): Implement in terms of get_adapters_addresses. * nt/inc/sys/socket.h: Add sys_htonl and sys_ntohl prototypes. * etc/NEWS: Announce IPv4/IPv6 changes in network-interface-list. * doc/lispref/processes.texi (Misc Network): Document updated arglist and return values for network-interface-list.

| | | | | | | | | | | * src/process.c (Fmake_network_process) [AF_INET6]: Only build ::1 localhost when IPv6 is supported. (Fnetwork_lookup_address_info) [AF_INET6]: Move check for Qipv6 inside ifdef, since its definition depends on AF_INET6. Don't return IPv6 addresses when they're not supported. * test/src/process-tests.el (lookup-family-specification, lookup-google): Only do IPv6 lookup if IPv6 is supported.

* Update some URLsPaul Eggert2019-09-231-2/+1
| | | | | | | | | | | | | | | | | This mostly changes http: to https: in URLs. It also updates some URLs that have moved, removes some URLs that no longer work, recommends against using procmail (procmail.org no longer works), and removes some mentions of the no-longer-existing Gmane, LPF and VTW. It doesn't update all URLs, just the ones I had time for. * GNUmakefile (help): * admin/admin.el (manual-doctype-string): * admin/charsets/Makefile.in (${charsetdir}/ALTERNATIVNYJ.map): * admin/charsets/mapconv: * lisp/net/soap-client.el (soap-create-envelope): * lisp/org/org.el (org-doi-server-url): * lisp/textmodes/bibtex.el (bibtex-generate-url-list): Prefer https: to http: un URLs.

* Fix compilation of process.cRobert Pluim2019-08-231-1/+1
| | | | | * src/process.c (network_lookup_address_info_1): [!HAVE_GAI_STRERROR]: Use make_fixnum instead of make_number. (Bug#37158).
* Get the Gnutls code compiling on Fedora 30Paul Eggert2019-08-231-15/+11
| | | | | | | | | | | | | | | | | | | | The recent changes caused the build to fail on Fedora 30 when built with --enable-gcc-warnings, among other things with diagnostics that gnutls_compression_get and gnutls_compression_get_name are deprecated (this started with GnuTLS 3.6). Fix this by refusing to call these obsolescent and now-dummy functions in GnuTLS 3.6 and later. However, this is just a temporary workaround to get the build working; a real fix is needed, as network-stream-tests fail. * src/gnutls.c (HAVE_GNUTLS_COMPRESSION_GET): New macro. (gnutls_compression_get, gnutls_compression_get_name): Define only if HAVE_GNUTLS_COMPRESSION_GET. (init_gnutls_functions): Load the two functions only if HAVE_GNUTLS_COMPRESSION_GET. (emacs_gnutls_certificate_export_pem): Use alloca instead of xmalloc. (Fgnutls_peer_status): Just return "NULL" if the functions are deprecated. (Fgnutls_format_certificate): Fix pointer signedness glitches. * src/process.c: Fix spacing.

Inline the set_process_filter_masks call instead of fixing it that function, because it is also called from connect_network_socket, and we don't want to change the behavior of that function so close to release. * test/src/process-tests.el (set-process-filter-t): New test.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | printmax_t etc. were needed only for platforms that lacked support for printing intmax_t. These platforms are now so obsolete that they are no longer practical porting targets. * src/image.c (gs_load): Fix unlikely buffer overrun discovered while making these changes. It was introduced in 2011-07-17T00:34:43!eggert@cs.ucla.edu. * src/lisp.h (printmax_t, uprintmax_t, pMd, pMu, pMx): Remove.

Separate these rare uses out into XFIXNUM_RAW and XUFIXNUM_RAW. Problem and original patch reported by Pip Cet (Bug#36370). * src/ccl.c (Fccl_execute_on_string): * src/fileio.c (Finsert_file_contents, a_write) (Fdo_auto_save): * src/process.c (conv_lisp_to_sockaddr): * src/textprop.c (Fnext_single_char_property_change) (Fprevious_single_char_property_change) (Fnext_property_change, Fnext_single_property_change) (Fprevious_property_change) (Fprevious_single_property_change): Don’t assume fixnums are nonnegative. * src/ccl.c (Fccl_execute_on_string): Fix range-checking bug if AREF (status, i) is out of int range. * src/data.c (arith_driver): Use XFIXNUM_RAW as we want efficient garbage if the value is not a fixnum. * src/dosfns.c (Fint86, Fdos_memput): Check that args are nonnegative. * src/image.c (lookup_image): Check that args are in range. * src/lisp.h (lisp_h_XHASH): Use XUFIXNUM_RAW, since this is for hashing. (lisp_h_XFIXNAT, XFIXNAT) [USE_LSB_TAG]: Remove macros. (lisp_h_XFIXNUM_RAW, XFIXNUM_RAW) [USE_LSB_TAG]: New macros, with the semantics of the old macros without _RAW. (XFIXNUM_RAW, XUFIXNUM_RAW): New inline functions, with the semantics of the old functions without _RAW. (FIXNUMP): Move definition up to avoid forward use. (XFIXNUM, XFIXNAT, XUFIXNUM): Use eassume to add a runtime check (when debugging) that the argument has the proper form. (XFIXNUM, XFIXNAT): Now inline functions only, since they refer to their arguments more than once now that they use eassume. * src/textprop.c (Fprevious_single_char_property_change): Avoid fixnum overflow with invalid input. (set_text_properties): Fix unlikely failure to validate arguments, by using EQ instead of XFIXNAT. * src/w32term.c (w32_draw_glyph_string): * src/xterm.c (x_draw_glyph_string): Treat negative minimums as 0 rather than as garbage patterns.
