* | Set last-coding-system-used upon ASCII conversion bypass (bug#40407)Mattias Engdegård2020-04-091-1/+2
| | | | | | | | | | | | | | | | Spotted by Kazuhiro Ito. * src/coding.c (code_convert_string): Set Vlast_coding_system if appropriate. * test/src/coding-tests.el (coding-nocopy-ascii): Add test.
* | Fix ASCII-only conversion logic (bug#40407)Mattias Engdegård2020-04-091-12/+21
| | | | | | | | | | | | | | | | | | | | | | To sidestep conversion altogether when EOL conversion applies, we must either be encoding a string without NL, or decoding without CR. * src/coding.c (string_ascii_p): Revert to a pure predicate. (code_convert_string): Fix logic. Don't use uninitialised ascii_p (removed). Use memchr to detect CR or LF in string when needed. * test/src/coding-tests.el (coding-nocopy-ascii): Update tests to include encodings with explicit EOL conversions.

| | | | | | | | | | | | | | * src/coding.c (Fcheck_coding_systems_region): Don't crash if the third arg contains something that isn't a coding system. * test/src/coding-tests.el (coding-check-coding-systems-region): New test.
* | Fix decoding ASCII strings with embedded CR charactersEli Zaretskii2020-04-091-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | * src/coding.c (string_ascii_p): Return a negative value if an all-ASCII string STR includes the CR character, otherwise a positive value. (code_convert_string): If the string is ASCII, but includes CR characters, use the fast path only if EOL doesn't need to be decoded. (Bug#40519) * test/src/coding-tests.el (coding-nocopy-ascii): Add tests for bug#40519.
* | Avoid expensive recoding for ASCII identity cases (bug#40407)Mattias Engdegård2020-04-051-0/+11

* | Fix inverted NOCOPY encode/decode parameter (bug#40407)Mattias Engdegård2020-04-051-0/+8
| | | | | | | | | | | | | | | | | | | | In {encode,decode}-coding-string, the NOCOPY parameter had the opposite effect to what was intended and documented. This 18 year old bug (introduced in 4031e2bf0a) only affected calls with CODING-SYSTEM being nil. * src/coding.c (code_convert_string): Correct use of NOCOPY. * test/src/coding-tests.el (coding-nocopy-trivial): New test.
* | Port the 'module/async-pipe' test to MS-WindowsEli Zaretskii2020-03-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These changes let the code compile and produce a valid DLL, but the test hangs. It looks like the hang is in Fdelete_process, when it closes one of the descriptors of the pipe process. In addition, this use of the pipe process cannot currently work on MS-Windows, since make-pipe-process doesn't set up the reader thread to read from the Emacs's side of the pipe, so the select emulation doesn't know there's stuff to read from that pipe. * test/data/emacs-module/mod-test.c [WINDOWSNT]: Include windows.h. (ALIGN_STACK) [!__x86_64__]: Define for 32-bit builds. (sleep_for_half_second): New function. (write_to_pipe): Declare return type differently for WINDOWSNT. Call sleep_for_half_second. (Fmod_test_async_pipe) [WINDOWSNT]: Use _beginthread as substitute for pthread_create. (invalid_finalizer): Replace non_ASCII character in a comment. * test/src/emacs-module-tests.el (module/async-pipe): Skip on MS-Windows, as the test fails and then hangs.
* | Add a module function to open a file descriptor connected to a pipe.Philipp Stephani2020-03-261-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | Fix rounding errors in time conversionPaul Eggert2020-03-031-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | * src/timefns.c (frac_to_double): Pass FLT_RADIX to mpz_sizeinbase instead of doing the radix calculation ourselves, not always correctly. Fix off-by-one error in scale, which caused double-rounding. (decode_time_components): Use frac_to_double (via decode_ticks_hz) to fix double-rounding error that can occur even though intermediate results are long double. * test/src/timefns-tests.el (float-time-precision): Test the above fixes.
* | Port timestamp tests to odd timezones, (TICKS . HZ)Paul Eggert2020-02-271-23/+23
| | | | | | | | | | | | | | | | | | | | | | | | * test/src/timefns-tests.el: (format-time-string-padding-minimal-deletes-unneeded-zeros) (format-time-string-padding-minimal-retains-needed-zeros) (format-time-string-padding-spaces) (format-time-string-padding-zeros-adds-on-insignificant-side): Don't assume local time can represent 2000-02-15 00:00:00, as there might be a DST jump over midnight. Work even when timestamps are of (TICKS . HZ) form. Simplify by avoiding need to call time-add.

This fixes case-insensitive completion when all the candidates are identical but for the letter-case. (Bug#11339)
* Ensure building and running on non-IPv6 capable hosts worksRobert Pluim2019-11-081-5/+6
| | | | | | | | | | | * 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.
* Don’t signal overflow for (expt 1 bignum)Paul Eggert2019-11-041-0/+5
| | | | | | | | Similarly for (expt 0 bignum) and (expt -1 bignum). The result is always a -1, 0 or 1, so do not signal overflow. * src/data.c (expt_integer): Do not signal an overflow if -1 <= X <= 1. Be clearer about when overflow is signaled. * test/src/floatfns-tests.el (bignum-expt): Test this.
* Fix print.c infloop on circular listsPaul Eggert2019-10-301-1/+5
| | | | | | | | | | | | | | Fix infinite loops in print.c when a circular list is passed to command-error-default-function or to error-message-string. * src/print.c (print_error_message): Use FOR_EACH_TAIL to avoid infloop on circular lists. (print_object): Use FOR_EACH_TAIL_SAFE, as it uses Brent’s teleporting tortoise-hare algorithm which is asymptotically better than the classic tortoise-hare algorithm that the code wsas using. * test/src/print-tests.el (print-circle-2): When print-circle is nil, do not insist on a particular cycle-detection heuristic. (error-message-string-circular): New test.
* Fix fileio.c infloops on circular listsPaul Eggert2019-10-301-0/+9
| | | | | | | | | | | | | Fix infinite loops in fileio.c when a circular list is the value of after_insert_file_functions, buffer-auto-save-file-format, buffer-file-format, or write-region-annotate-functions. * src/fileio.c (Finsert_file_contents, build_annotations): Use FOR_EACH_TAIL to avoid infloop on circular lists. (build_annotations): Use an EMACS_INT, not an int, to count nesting level. * test/src/fileio-tests.el: (fileio-tests--circular-after-insert-file-functions): New test.
* Add tests for secure-hash and improve doc string (Bug#37420)Stefan Kangas2019-10-041-0/+18
| | | | | | * src/fns.c (Fsecure_hash_algorithms): Fix typo. (Fsecure_hash): Add algorithm list to doc string. * test/src/fns-tests.el (test-secure-hash): New test.
* Update a substitute-command-keys testGlenn Morris2019-10-011-0/+1
| | | | | * test/src/doc-tests.el (doc-test-substitute-command-keys): Update for recent minibuffer map change.
* Remove support for destructive splicing in elispStefan Kangas2019-09-261-0/+7
| | | | | | | | | | * src/lread.c (read1): Don't handle destructive splicing in backquote expressions (e.g. ",.<identifier>"). (Bug#19790) (syms_of_lread): Remove Qcomma_dot. * src/print.c (print_object): Don't check for Qcomma_dot. * test/src/eval-tests.el (eval-tests-19790-backquote-comma-dot-substitution): New test. * etc/NEWS: Announce it.
