* Assume NON_BLOCKING_CONNECT (Bug#22946)Paul Eggert2016-03-221-48/+5
| | | | | | | | | | * lisp/proced.el (proced-signal-list): Omit comment about obsolete systems that do not support POSIX 1003.1-2001 signals. * src/process.c (NON_BLOCKING_CONNECT): Remove, since we can now assume POSIX 1003.1-2001 or better here. Assume it’s defined. (connect_network_socket): Assume EINPROGRESS is defined, as that’s portable too now. (Fmake_network_process): Use bool for boolean.

| * Rework C source files to avoid ^(Paul Eggert2016-03-101-11/+11
| | | | | | | | | | | | | | | | Work around Bug#22884 by rewording comments and strings to avoid ‘(’ at the start of a line unless it starts a function. This change is a short-term hack; in the longer run we plan to fix cc-mode’s performance for C files that have ‘(’ at the start of a line in a comment or string.
| * src/process.c Correctly convert AF_INET6 addressesDavid Edmondson2016-02-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | * src/process.c (conv_lisp_to_sockaddr): AF_INET6 addresses are converted to a list of 16 bit quantities by conv_sockaddr_to_lisp(). conv_lisp_to_sockaddr() should follow the same scheme rather than expecting a (longer) list of 8 bit quantities. Backport: (cherry picked from commit 55ce3c30d617c38eb086d5ad4ffbd881c20c559c)
* | Minor fixes for getaddrinfo_a usagePaul Eggert2016-03-091-25/+23
| | | | | | | | | | | | | | | | | | * src/process.c (Fdelete_process): Check gai_cancel return value. That way, there’s no need to invoke gai_error. Check gai_suspend return value. (Fmake_network_process): Don’t assume gai_strerror returns a UTF-8 string. Simplify call to connect_network_socket. (check_for_dns): Avoid unnecessary initialization of local.
* | Assume getaddrinfo in C codePaul Eggert2016-03-071-64/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * admin/CPP-DEFINES, configure.ac: Remove HAVE_GETADDRINFO, HAVE_H_ERRNO. All uses removed. * doc/lispref/processes.texi (Network, Network Processes), etc/NEWS: Say that port numbers can be integer strings. * lib-src/pop.c (h_errno) [!WINDOWSNT && !HAVE_H_ERRNO]: Remove decl. (socket_connection): Assume HAVE_GETADDRINFO. * lisp/mpc.el (mpc--proc-connect): * lisp/net/network-stream.el (open-network-stream): It’s now OK to use integer strings as port numbers. * src/process.c (conv_numerical_to_lisp) [!HAVE_GETADDRINFO]: Remove. (Fmake_network_process): Assume HAVE_GETADDRINFO.
* | Remove support for IRIXPaul Eggert2016-03-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IRIX port wasn’t really working anyway, and the code was getting in the way of other changes (e.g., getaddrinfo fixes). IRIX’s supplier dropped support for IRIX in 2013. * admin/CPP-DEFINES: * configure.ac (opsys): * doc/lispref/os.texi (System Environment): * etc/MACHINES, etc/PROBLEMS: * lisp/find-dired.el (find-grep-options): * lisp/lpr.el (lpr-lp-system): * lisp/ls-lisp.el (ls-lisp-emulation): * lisp/mail/rmail.el (rmail-spool-directory): * lisp/net/net-utils.el (ping-program-options): * lisp/progmodes/gud.el (gud-irix-p, gud-dbx-use-stopformat-p): * lisp/progmodes/ps-mode.el (ps-mode-print-function): * src/conf_post.h [IRIX6_5]: * src/emacs.c (Vsystem_type): * src/filelock.c (get_boot_time_1): * src/process.c (process_send_signal): * src/unexelf.c (unexec): Omit IRIX-specific code and/or documentation. * configure.ac (NON_GCC_TEST_OPTIONS, IRIX6_5, PREFER_VSUSP): Remove. All uses removed. * etc/NEWS: Document the change.
* | Ensure TLS negotiation progressLars Ingebrigtsen2016-03-031-5/+29
| | | | | | | | | | | | | | | | * src/gnutls.h (GNUTLS_EMACS_HANDSHAKES_LIMIT): Increase the number of retries so that we try for about a minute. * src/process.c (wait_reading_process_output): Ensure progress for DNS resolution and TLS negotiation.
* | Stop calling res_initPaul Eggert2016-02-291-13/+0
| | | | | | | | | | | | | | | | | | | | | | | | Emacs shouldn’t need to call res_init any more, now that nscd or equivalent is everywhere. On modern systems, calling res_init simply slows Emacs down. On ancient systems lacking nscd Emacs will still work well enough with this change; it’s just that it won’t respond to changes in /etc/resolv.conf. * configure.ac (HAVE_RES_INIT): Remove. Worry about -lresolv only when configured --with-hesiod. Hesiod is still used; see, e.g.: https://soylentnews.org/meta/article.pl?sid=15/07/13/0255214 * src/Makefile.in (LIBRESOLV): Remove. All uses removed.
* | * src/process.c (Fdelete_process): Simplify cast.Paul Eggert2016-02-291-2/+1

* | Wait for async DNS to complete before freeing resourcesLars Ingebrigtsen2016-02-291-1/+17
| | | | | | | | | | * src/process.c (Fdelete_process): Wait for async DNS to complete before freeing the data structures it needs.
* | Integer overflow cleanups for ports and socklenPaul Eggert2016-02-251-34/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/process.c (struct sockaddr_and_len, conv_sockaddr_to_lisp) (get_lisp_to_sockaddr_size, Fset_process_datagram_address) (connect_network_socket): Use ptrdiff_t, not int, for signed object sizes. This addresses only a theoretical problem, as in practice these object sizes are less than 2**31, but we might as well use the same style here as elsewhere in Emacs. (string_integer_p): Remove; all uses removed. (Fmake_network_process): Check that port number is in range. When converting an integer-string service, rely on strtol rather than rechecking the string by hand. * src/process.h, src/w32.c (conv_sockaddr_to_lisp): Adjust prototypes to match.
* | Allow using "number strings" as services on non-GNU systemsLars Ingebrigtsen2016-02-251-0/+15
| | | | | | | | | | | | | | * src/process.c (string_integer_p): New function. (Fmake_network_process): Use it to allow connecting to services specified as "993" even when getaddrbyname isn't available.
* | Make setting the coding system non-blockingLars Ingebrigtsen2016-02-241-14/+13
| | | | | | | | | | | | * src/process.c (Fset_process_filter_multibyte): Defer completing coding system setup in asynchronous processes. (Fset_process_coding_system): Ditto.
* | Port to --enable-gcc-warnings sans getaddrinfo_aPaul Eggert2016-02-231-5/+4
| | | | | | | | | | | | | | * src/process.c (Fmake_network_process): Add ATTRIBUTE_UNUSED to a local unused when getaddrinfo_a is missing. Resize portbuf to size needed. Do cheap test first. Move local to block where it’s needed.
* | Minor cleanups for async DNS etc.Paul Eggert2016-02-231-123/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/frame.h (FRAME_WINDOW_CONFIGURATION_CHANGED): Omit unnecessary parens. * src/gnutls.c (gnutls_try_handshake, emacs_gnutls_deinit) (gnutls_verify_boot): Use bool for boolean. (ATTRIBUTE_FORMAT_PRINTF): Add printf attribute. * src/process.c (free_dns_request, Fmake_network_process): Allocate and free async request control block all in one go. (set_network_socket_coding_system, finish_after_tls_connection) (connect_network_socket): Now static. (conv_numerical_to_lisp): 2nd arg is now int, not unsigned. (Fmake_network_process): Use list1 for brevity. (wait_for_socket_fds): 2nd arg is now const ptr. * src/process.h (struct Lisp_Process.dns_request): Now struct gaicb *, not struct gaicb **, since there was always exactly one. All uses changed. * src/window.c, src/window.h (run_window_configuration_change_hook): Now static.

* | Mention in the doc strings that process functions may blockLars Ingebrigtsen2016-02-221-7/+26
| | | | | | | | | | | | | | | | (Fprocess_contact, Fprocess_datagram_address) (Fset_process_datagram_address, Fset_network_process_option) (Fprocess_send_region, Fprocess_send_string): Mention that the functions may block. (Fset_process_coding_system): Ditto.
* | Add blocker warnings to the *Messages* bufferLars Ingebrigtsen2016-02-221-3/+3
| | | | | | | | | | | | * src/process.c (wait_for_socket_fds): Add warning to the log. (wait_while_connecting): Ditto. (wait_for_tls_negotiation): Ditto.
* | Respect DNS timeoutsAlain Schneble2016-02-211-1/+1
| | | | | | | | | | | | * src/process.c (check_for_dns): If the async DNS request failed and the associated process is still in "connect" state, deactivate the process and set status to "failed".
* | Fix coding system setupLars Ingebrigtsen2016-02-191-7/+5
| | | | | | | | | | * src/process.c (set_network_socket_coding_system): Pass in the host/service that's been computed already.
* | Verify the TLS connection asynchronouslyLars Ingebrigtsen2016-02-181-1/+4
| | | | | | | | | | | | | | | | | | * src/gnutls.c (gnutls_verify_boot): Refactor out into its own function so that we can call it asynchronously. (Fgnutls_boot): Use it. * src/process.c (wait_reading_process_output): Verify the TLS negotiation.
* | Deactivate the correct processLars Ingebrigtsen2016-02-161-1/+1
| | | | | | | | | | * src/process.c (wait_reading_process_output): Deactivate the correct process on failure.
* | Implement asynch TLS negotiationLars Ingebrigtsen2016-02-161-47/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | * src/gnutls.c (gnutls_try_handshake): Factor out into its own function. (emacs_gnutls_handshake): Use it. (emacs_gnutls_read): Just return instead of retrying the handshake. * src/process.c (finish_after_tls_connection): Factor out into its own function. (connect_network_socket): Use it. (wait_reading_process_output): Retry TLS handshakes. (wait_reading_process_output): Defer sentinel until TLS completes.
* | Simplify the DNS resolution loop a bitLars Ingebrigtsen2016-02-161-25/+10
| | | | | | | | | | * src/process.c (wait_reading_process_output): Simplify the DNS resolution loop a bit.
* | Loop over the process list instead of maintaining a separate listAlain Schneble2016-02-161-53/+33
| | | | | | | | | | | | | | * src/process.c: Remove declaration/definition of dns_processes list. * src/process.c (wait_reading_process_output): Loop over all processes in Vprocess_alist instead of dns_processes, to check for completed DNS requests.

| | | | | | | | | | | | | | * src/process.c (Fset_process_filter): Don't set the socket masks here, because we may not have a socket yet. (set_process_filter_masks): New function. (connect_network_socket): Set the filter masks here.
* | Ensure we always free DNS resources when deleting a processLars Ingebrigtsen2016-02-161-12/+31
| | | | | | | | | | | | | | * src/process.c (free_dns_request): Factor out into own function. (Fdelete_process): When deleting a process, free any DNS structures associated with it. (check_for_dns): Always free all DNS resources.
* | Don't block in set-process-window-sizeAlain Schneble2016-02-161-4/+2
| | | | | | | | | | | | | | * src/process.c (set-process-window-size): Explicitly return Qnil when called with network processes as set_window_size won't work anyway on socket fds. As a welcome side effect, this makes the blocking wait_for_socket_fds call obsolete.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisp/net/network-stream.el (network-stream-open-tls): Postpone NSM verification when running async. * src/process.c (Fset_process_filter): This function doesn't need to wait. (connect_network_socket): Set the process status to "run" only after TLS negotiation. (wait_for_socket_fds): Take a name parameter for more debugging. (wait_reading_process_output): Don't change status to "run" unless TLS negotiation has finished. (send_process): Wait for the process here instead of send_process_string. (connect_network_socket): Call the network security manager.
* | Remove some #ifdefs and update documentationLars Ingebrigtsen2016-02-151-48/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * doc/lispref/processes.texi (Network Processes): Remove mention of `dns'. * lisp/net/network-stream.el (open-network-stream): Remove mention of `dns'. * src/process.c (Fset_process_filter) (Fset_process_window_size, Fprocess_contact) (Fprocess_datagram_address, Fset_process_datagram_address) (Fset_network_process_option, Fprocess_send_region) (Fprocess_send_string, Fset_process_coding_system) (Fset_process_filter_multibyte): Remove the #ifdef HAVE_GETADDRINFO_A checks. (Fprocess_send_string): Wait for TLS negotiation. (wait_for_tls_negotiation): New function. (send_process): Remove the TLS boot check. * src/process.c (Fmake_network_process): Ditto.

| | | | | | | | | | | | | | | | | | | | | | | | * src/process.c (set-process-filter, set-process-window-size, process-contact, process-datagram-address, set-process-datagram-address, set-network-process-option): Make functions wait (block) on network process until pending DNS requests have been processed and associated socket initialized. * src/process.c (process-send-region, process-send-string, process-send-eof): Make functions wait (block) while network process is in connect state.
* | src/process.c Correctly convert AF_INET6 addressesDavid Edmondson2016-02-091-1/+1
| | | | | | | | | | | | | | | | * src/process.c (conv_lisp_to_sockaddr): AF_INET6 addresses are converted to a list of 16 bit quantities by conv_sockaddr_to_lisp(). conv_lisp_to_sockaddr() should follow the same scheme rather than expecting a (longer) list of 8 bit quantities.
* | Make url.el use async DNSLars Ingebrigtsen2016-02-051-0/+3
| | | | | | | | | | | | | | * lisp/url/url-gw.el (url-open-stream): Use non-blocking DNS. * src/process.c (syms_of_process): Add a `dns' subfeature for make-network-process.
