* Remove all occurences of the mb_ptr2char macroZviRackover2018-08-06
| | | | | | | First step towards implemening issue #7401. The same can be done for all deprecated mb_ functions in follow-up patches.
* vim-patch:8.0.0451: some macros are in lower caseJan Edmund Lazo2018-06-12
| | | | | | | Problem: Some macros are in lower case. Solution: Make a few more macros upper case. Avoid lower case macros use an argument twice. https://github.com/vim/vim/commit/91acfffc1e6c0d8c2abfb186a0e79a5bf19c3f3f
* vim-patch:8.0.0520: using a function pointer while the function is known (#8513)KunMing Xie2018-06-10
| | | | | | | Problem: Using a function pointer instead of the actual function, which we know. Solution: Change mb_ functions to utf_ functions when already checked for Unicode. (Dominique Pelle, closes vim/vim#1582) https://github.com/vim/vim/commit/ace95989ed81929a84e205b26d0972cb9d6b4b19

* vim-patch:8.0.0623: error for invalid regexp is not very informativeJan Edmund Lazo2018-06-04
| | | | | | Problem: The message "Invalid range" is used for multiple errors. Solution: Add two more specific error messages. (Itchyny, Ken Hamada) https://github.com/vim/vim/commit/966e58e413ffa88af8d748e697aa2999571fcd7b
* vim-patch:8.0.0519: character classes not well tested (#8460)KunMing Xie2018-06-01
| | | | | | | | | Problem: Character classes are not well tested. They can differ between platforms. Solution: Add tests. In the documentation make clear which classes depend on what library function. Only use :cntrl: and :graph: for ASCII. (Kazunobu Kuriyama, Dominique Pelle, closes vim/vim#1560) Update the documentation. https://github.com/vim/vim/commit/0c078fc7db2902d4ccba04506db082ddbef45a8c
* regexp_nfa: Silence PVS/V560: current code is more obviousZyX2018-04-22
| | | | | While warning is technically true (cannot enter this case with `state->c` greater then NFA_Z…9) it makes condition less readable and relies on knownledge of enum internal structure.
* lintJames McCoy2018-01-02

* vim-patch:8.0.0160: EMSG() is sometimes used where it should be IEMSG()James McCoy2018-01-02
| | | | | | | Problem: EMSG() is sometimes used for internal errors. Solution: Change them to IEMSG(). (Dominique Pelle) And a few more. https://github.com/vim/vim/commit/de33011ec623fd562419dede6bf465b5b9881a20
* vim-patch:8.0.0165 (#7132)KunMing Xie2017-08-10
| | | | | | Problem: Ubsan warns for integer overflow. Solution: Swap two conditions. (Dominique Pelle) https://github.com/vim/vim/commit/f446b48ff0bffae2b453cd4f9e3c25dfe363d29d
* vim-patch:8.0.0020Jurica Bradaric2017-07-29
| | | | | | | Problem: The regexp engines are not reentrant. Solution: Add regexec_T and save/restore the state when needed. https://github.com/vim/vim/commit/6100d02aab7c8294b581cb299250eea164b50e9d
* vim-patch:7.4.2354Shougo Matsushita2017-07-12
| | | | | | | | Problem: The example that explains nested backreferences does not work properly with the new regexp engine. (Harm te Hennepe) Solution: Also save the end position when adding a state. (closes vim/vim#990) https://github.com/vim/vim/commit/d563883a1fb5ec6cf4a2758c5e36ac1ff4e9bb3d
* regexp_nfa: Fix invalid fallthrough in character class detectionJames McCoy2017-05-12
| | | | | | | | | When the end character in a range matches a different standard range (e.g., [0-z]), the range would be incorrectly detected as the class of the end character (CLASS_az). Instead of using a fallthrough, immediately FAIL when the end character doesn't match the expected range.
* *: Comment intentional fallthroughsJames McCoy2017-05-12
| | | | | Falling through a switch case should be commented so it's clear that behavior is intentional.
* Merge #6460 from ZyX-I/1476-changesJustin M. Keyes2017-05-08

* vim-patch:7.4.2355Justin M. Keyes2017-03-22
| | | | | | | | Problem: Regexp fails to match when using "\>\)\?". (Ramel) Solution: When a state is already in the list, but addstate_here() is used and the existing state comes later, add the new state anyway. https://github.com/vim/vim/commit/16b3578f355282846f2600ce77fb344950f0b9ce
* vim-patch:7.4.1793Michael Ennen2016-12-31
| | | | | | | | Problem: Some character classes may differ between systems. On OS/X the regexp test fails. Solution: Make this less dependent on the system. (idea by Kazunobu Kuriyama) https://github.com/vim/vim/commit/e8aee7dcf9b12becff86e8ce1783a86801c5f9f6
* vim-patch:7.4.1708James McCoy2016-12-06
| | | | | | | | | | | Problem: New regexp engine does not work properly with EBCDIC. Solution: Define equivalence class characters. (Owen Leibman) https://github.com/vim/vim/commit/2a6fa564a3b5061c14ff63b8b0f12801df0b0ac2 Although nvim doesn't support EBCDIC systems, this keeps us inline with upstream code so its easier to merge future patches in this area and improves the readability of the code.

* vim-patch:7.4.613James McCoy2016-04-25
| | | | | | | Problem: The NFA engine does not implement the 'redrawtime' time limit. Solution: Implement the time limit. https://github.com/vim/vim/commit/70781ee4035b5fd5e3cbb3fe4c7646e19119f0a8

| | | | | | | | | | | | | Problem: Using uninitialized memory for regexp with back reference. (Dominique Pelle) Solution: Initialize end_lnum. https://github.com/vim/vim/commit/c2b717ebd6719e722dcb5f10e4c74033a53ff7c7 --- see: "[bug] use of uninitialized memory in regexp_nfa.c with invalid back reference" https://groups.google.com/d/msg/vim_dev/JWmrT5-NnPQ/U_TgaRW8AwAJ
* regexp_nfa.c: Speed up find_match_text()oni-link2016-01-24
| | | | | | | | | | | | | An extra test in commit 0a116c828debc6192a6bfb6bceb8cf020e867db0 was introduced, to check for end of string with a call to strlen(). This was necessary, because an incorrect length for invalid byte sequences was used to step through the string. This slowed down find_match_text() compared to vim's version. To speed up things, the extra check was removed and a sequence length of 1 for invalid byte sequences is used. Fixes issue #3486
* vim-patch:7.4.715 #4003Michael Ennen2016-01-13
| | | | | | | | Problem: Invalid memory access when there are illegal bytes. Solution: Get the length from the text, not from the character. (Dominique Pelle) https://github.com/vim/vim/commit/2186ffa2c7d8a9e2cb09316a7ac9e4ade3957c2f

* vim-patch:7.4.651 #3644Shougo Matsushita2015-11-10
| | | | | | | | Problem: Can't match "%>80v" properly for multi-byte characters. Solution: Multiply the character number by the maximum number of bytes in a character. (Yasuhiro Matsumoto) https://github.com/vim/vim/commit/4f36dc3bf7118a3fa5ccdae1a37963860dc71e6c
