Bug#46641
The network-stream-tests actually work fine when the local machine has
no IP at all, but cause a crash in the GnuTLS library when there is an
IP configured but the interface is down.
* test/lisp/net/network-stream-tests.el (internet-is-working): New
defvar, checks if we can resolve "google.com".
(connect-to-tls-ipv4-nowait, connect-to-tls-ipv6-nowait)
(open-network-stream-tls-nowait, open-gnutls-stream-new-api-nowait)
(open-gnutls-stream-old-api-nowait): Use it to check for working
Internet access.
* test/src/process-tests.el (internet-is-working): New defvar, checks
if we can resolve "google.com".
(lookup-family-specification, lookup-unicode-domains)
(unibyte-domain-name, lookup-google, non-existent-lookup-failure): Use
it to check for working Internet access.
(edebug-tests-trivial-backquote): Adjust to the way `eval-defun`
outputs its result.
(edebug-tests-cl-macrolet): Adjust to the fact that now macro expansion
takes place during the `eval-defun` even when Edebugging.
Newer standards like RFC 8259, which obsoletes the earlier RFC 4627,
now allow any top-level value unconditionally, so Emacs should too.
* src/json.c (Fjson_serialize, Fjson_insert): Pass JSON_ENCODE_ANY to
allow serialization of any JSON value. Call 'lisp_to_json' instead of
'lisp_to_json_toplevel'. Remove obsolete comments
(neither JSON_DECODE_ANY nor JSON_ALLOW_NUL are allowed here). Reword
documentation strings.
(Fjson_parse_string, Fjson_parse_buffer): Pass JSON_DECODE_ANY to
allow deserialization of any JSON value. Reword documentation
strings.
(lisp_to_json_nonscalar, lisp_to_json_nonscalar_1): Rename from
"toplevel" to avoid confusion.
(lisp_to_json): Adapt caller.
* test/src/json-tests.el (json-serialize/roundtrip-scalars): New unit
test.
* doc/lispref/text.texi (Parsing JSON): Update documentation.
* doc/lispref/positions.texi (Text Lines): Revert previous change.
* lisp/simple.el (line-number-at-pos): Remove definition.
* lisp/simple.el (count-lines): Revert back to using
`forward-line', because there seems to be a disagreement on how
lines should be counted in a region...
* src/fns.c (Fline_number_at_pos): Rename from
Fline_number_at_position and adjust parameter list.
* doc/lispref/positions.texi (Text Lines): Document it.
* lisp/simple.el (count-lines): Use it.
(line-number-at-pos): Ditto.
* src/fns.c (Fline_number_at_position): New function (bug#22763).
* src/editfns.c (styled_format): Fix accounting for text
properties that come from the format string. (Bug#46317)
* test/src/editfns-tests.el (format-properties): Add new tests for
bug#46317.
* test/src/process-tests.el (process-tests/multiple-threads-waiting):
Also check that 'thread-join' and 'thread-last-error' return the
expected errors.
This unit test tests that we can call 'accept-process-output' in
parallel from multiple threads.
* test/src/process-tests.el (process-tests/multiple-threads-waiting):
New unit test.
That way, the tests only depend on Emacs, and not on utilities that
might not be available during test time.
* test/src/process-tests.el (process-tests--eval)
(process-tests--emacs-command, process-tests--emacs-binary)
(process-tests--dump-file)
(process-tests--usable-file-for-reinvoke): New helper functions.
(process-tests/sentinel-called)
(process-tests/sentinel-with-multiple-processes): Use them.
When we're trying to notify a process about a status change, we need
to ignore the SIGCHLD pipe temporarily, otherwise the code would
likely not run into the timeout case that's necessary for a status
change to happen.
* src/process.c (wait_reading_process_output): Ignore the SIGCHLD pipe
when notifying a process about a status change.
* test/src/process-tests.el (process-tests/sentinel-called)
(process-tests/sentinel-with-multiple-processes): New unit tests.
If we receive and handle a SIGCHLD signal for a process while waiting
for that process, 'pselect' might never return. Instead, we have to
explicitly 'pselect' that the process status has changed. We do this
by writing to a pipe in the SIGCHLD handler and having
'wait_reading_process_output' select on it.
* src/process.c (child_signal_init): New helper function to create a
pipe for SIGCHLD notifications.
(child_signal_read, child_signal_notify): New helper functions to
read from/write to the child signal pipe.
(create_process): Initialize the child signal pipe on first use.
(handle_child_signal): Notify waiters that a process status has
changed.
(wait_reading_process_output): Make sure that we also catch
SIGCHLD/process status changes.
* test/src/process-tests.el
(process-tests/fd-setsize-no-crash/make-process): Remove workaround,
which is no longer needed.
First, scan to find the first non-whitespace character and then
backtrack to find the beginning of the line. The previous
algorithm always started on the non-whitespace character during
the backtrack, causing it to stop immediately and not actually
find the beginning of the line. The same applies to the end of
line calculation.
* src/xdisp.c: (Fwindow_text_pixel_size): Fix off by one error.
(Bug#45748)
* test/src/xdisp-tests.el (xdisp-tests--window-text-pixel-size)
(xdisp-tests--window-text-pixel-size-leading-space)
(xdisp-tests--window-text-pixel-size-trailing-space): New tests.
* test/src/process-tests.el (ipv6-is-available): New function for
checking whether we have a globally routable IPv6 prefix assigned.
(lookup-family-specification): Use 'ipv6-is-available' to check for
IPv6. Use 'localhost' instead of 'google.com' to test
'network-lookup-address-info' API.
(lookup-google): Use 'ipv6-is-available' to check for
IPv6.
* test/lisp/net/nsm-tests.el (nsm-ipv6-is-available): Rename to
'ipv6-is-available', make identical to the one in
test/src/process-tests.el.
Reported and reduced by Mauricio Collares.
* lisp/emacs-lisp/comp.el (comp-final): Fix coding system for the
tmp file used to pass data the child processes.
* test/src/comp-tests.el (45603-1): New testcase
* test/src/comp-test-45603.el : New File.
Be consistent when pretty-printing keys: put modifiers outside <>,
thus the more logical C-M-<return> instead of <C-M-return>.
* src/keymap.c (Fsingle_key_description):
Skip modifier prefix before adding <>.
* doc/lispref/help.texi (Describing Characters): Update example.
* doc/lispref/debugging.texi (Backtraces):
* doc/lispref/minibuf.texi (Text from Minibuffer):
Use @kbd instead of @key.
* etc/NEWS: Announce the change.
* test/src/keymap-tests.el (keymap--key-description):
* test/lisp/subr-tests.el (subr--kbd): New tests.
The test 'process-tests/fd-setsize-no-crash/make-process' used to call
'sleep' to ensure that enough processes are live to trigger a
FD_SETSIZE overflow. However, we can just call 'cat' instead and
close standard input when done. That way, we only wait as long as
needed.
* process-tests.el
(process-tests/fd-setsize-no-crash/make-process): Invoke 'cat' instead
of 'sleep'. Close standard input to exit the 'cat' processes.
The 'process-tty-name' already provides the TTY name, we don't have
interrogate the TTY host.
* test/src/process-tests.el
(process-tests/fd-setsize-no-crash/make-serial-process): Use
'process-tty-name' instead of having the TTY host print its TTY
name. Check whether TTY names are unique.
(process-tests--new-pty, process-tests--with-temp-file): Remove;
no longer used.
Introduce 'unreachable' as LIMPLE operater so we can handle correctly
in the CFG functions throwing values or signaling errors.
* src/comp.c (retrive_block): Better error diagnostic.
(emit_limple_insn): Add `unreachable'.
(compile_function): Fix block iteration.
(syms_of_comp): Define 'Qunreachable'.
* lisp/emacs-lisp/comp.el (comp-block): New variable.
(comp-block-lap): Add `non-ret-insn' slot.
(comp-branch-op-p): New predicate.
(comp-limple-lock-keywords): Color `unreachable' as red.
(comp-compute-edges): Add `unreachable'.
(comp-fwprop-call): Store non returning function call.
(comp-fwprop*): Update.
(comp-clean-orphan-blocks, comp-rewrite-non-locals): New functions.
(comp-fwprop): Call `comp-rewrite-non-locals'.
* test/src/comp-tests.el (comp-tests-type-spec-tests): Add two
tests.
* test/src/comp-test-funcs.el (comp-test-non-local-1)
(comp-test-non-local-2, comp-test-non-local-3)
(comp-test-non-local-4): New functions.
This works even if another thread or process resets the resource limit
for open file descriptors, e.g., using 'prlimit' on GNU/Linux.
* src/process.c (create_process, create_pty, Fmake_pipe_process)
(Fmake_serial_process, connect_network_socket)
(server_accept_connection): Limit file descriptors to FD_SETSIZE.
* test/src/process-tests.el (process-tests--with-raised-rlimit): New
helper macro.
(process-tests--fd-setsize-test): Rename from
'process-tests--with-many-pipes'. Increase resource limit during test
if possible.
(process-tests/fd-setsize-no-crash/make-process)
(process-tests/fd-setsize-no-crash/make-pipe-process)
(process-tests/fd-setsize-no-crash/make-network-process)
(process-tests--new-pty): Rename callers.
