[ANNOUNCEMENT] Updated: wget-1.19.1-2
A new release of wget, 1.19.1-2, will be available soon for download from your favorite mirror, leaving 1.19.1-1 as previous. NEWS: = This is a rebuild, in order to fix CVE-2017-6508 as well as build against libidn2. See also the package documentation in /usr/share/doc/wget/. DESCRIPTION: GNU Wget is a file retrieval utility which can use either the HTTP, HTTPS, or FTP protocols. Wget features include the ability to work in the background while you're logged out, recursive retrieval of directories, file name wildcard matching, remote file timestamp storage and comparison, use of Rest with FTP servers and Range with HTTP servers to retrieve files over slow or unstable connections, support for Proxy servers, and configurability. UPDATE: === To update your installation, click on the "Install Cygwin now" link on the http://cygwin.com/ web page. This downloads setup.exe to your system. Save it and run setup, answer the questions and pick up 'wget' from the 'Web' category. DOWNLOAD: = Note that downloads from cygwin.com aren't allowed due to bandwidth limitations. This means that you will need to find a mirror which has this update, please choose the one nearest to you: http://cygwin.com/mirrors.html QUESTIONS: == If you want to make a point or ask a question the Cygwin mailing list is the appropriate place. -- Eric Blake volunteer cygwin wget package maintainer For more details on this list (including unsubscription), see: http://sourceware.org/lists.html -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

Can you > work with > this? Thanks again for trying to narrow things down. I have recompiled readline locally with optimizations turned off (so it's easier for me to see what's going on), and am set up to run gdb on bash with a given readline executable installed. If you have really narrowed the problem to rl_insert(), that's at least something I can investigate. But where I'm stuck now is what works for you and what you think is wrong. Is this something where I can start bash under mintty, or do I have to start under cmd? Right there, I already see a difference with the two environments. Starting from cmd, I did: c:\cygwin\bin> od -tx1 which displayed Ω ce a9 0z 003 so I did indeed insert GREEK CAPITAL LETTER OMEGA U+03A9. But trying the same thing under a bash session in minty shows: ê 000 c3 aa 0a 003 so that is not the same character. I'm not sure if a code page change is supposed to alter what I see. So I'm back to cmd to try and debug things. Next, I tried: c:\cygwin\bin> .\dash and again got Ω; pressing complains that ./dash: 1: Ω: not found However, when I try: c:\cygwin\bin> .\bash --norc the display shows :\251 and hitting wipes out that display without doing anything. So I _think_ I'm running into the problem you're describing, but want to make sure, since it is different based on whether I started bash from cmd or from mintty. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org signature.asc Description: OpenPGP digital signature

(gdb) b read (gdb) b select (gdb) c then in the first window, typed to get dash back to its input loop and the second window hit a breakpoint in read.

A second time around, and instead of using fin, I stepped through: 1118 { (gdb) n ...

So when entering a UTF-8 character to dash, the whole character lands in the buffer at once, while under bash (presumably, as I haven't debugged that far yet), bash must reconstruct the Unicode characters from the individual bytes. Stepping through the breakpoints on sees 0xce on the first read, and 0xa9 on the second. But, in between the two read breakpoints, the first terminal displayed ':'. So the input is still making it correctly INTO readline; but being munged on the way to output; and it very much looks like readline's fault rather than cygwin's. I'm still trying to put breakpoints in the right places (the call stack at read() points to rl_getc(), from rl_read_key(), from readline_internal_char()...), but this is at least to let you know how I'm tackling the issue, in case it helps someone else spot a solution faster than me by starting from the same information. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org signature.asc Description: OpenPGP digital signature

This looks like a bash prompt, but are you running bash inside mintty, or directly in a cmd window? When I first open a mintty window to get bash, I see: $ chcp.com Active code page: 437 and in that environment, typing displays nothing, but hitting then displays: -bash: $'\302\224': command not found which maps to \xc2\x94; I can confirm that with 'od -tx1'. Trying gives a different character (¦), as \xc2\xa6. When I then do $chcp.com 65001 Active code page 65001 I don't see any change in behavior. But if I first open a cmd window, with NO bash in the mix, I see: c:\cygwin\bin> chcp Active code page: 437 where both and output ö, and where 'od -tx1' confirms both sequences produce \xc3\xb6. Then switching code pages: c:\cygwin\bin> chcp 65001 Active code page: 65001 directly typing prints nothing, while 'od -tx1' still shows that it received \xc3\xb6. I have no idea how alt- sequences are mapped to code points (it is not as trivial as a conversion of base to get either the Unicode code-point of 0x96 or to the UTF-8 encoding), but it appears that the input within cmd is the same, while the choice of code page determines what the output will be. I also have no idea why the alt- sequences produce different inputs under cmd than under mintty. So knowing WHAT environment you are using is VITAL to me understanding the results you are seeing. At any rate, I definitely know that U+00F6 is encoded as \xc3\xb6 in UTF-8 (I confirmed that on Linux, with echo $'\xc3\xb6'). I _don't_ know what it is encoded as in Windows code page 437 or 65001. But a quick google later, and I see that for code page 437 (https://en.wikipedia.org/wiki/Code_page_437), ö is at codepoint 0x94 (decimal 148, octal 0224); meanwhile, 0xf6 is equal to decimal 246. Aha - maybe that explains the two alt- sequences under codepage 437: without a leading zero, you are typing the decimal position which looks up the character from the current code page; WITH a leading zero you are directly requesting the decimal encoding of a Unicode character. And trying some other sequences, I note that õ (LATIN SMALL LETTER O WITH TILDE' (U+00F5)) is not part of code page 437; so there is nothing I can type without a leading 0 to print one; conversely, trying which requests the same unicode character displays merely 'o' (apparently U+006f), which, when you lack o-with-tilde, is a reasonable fallback compared to printing nothing at all. Either way, the character requested by the alt-sequence in the cmd window is then transformed by Cygwin into the appropriate UTF-8 input for the tty stdin of the Cygwin child process. Hmm; repeating those sequences under 'od -tx1', when I try , I see something interesting: the moment I press 5 (while still holding alt), the display prints [G; then releasing alt prints o; the transcription is then 000 1b 1b 5b 47 c3 b5 0a which is ESC ESC [ G (hmm - that's the ANSI terminal escape sequence for moving to column 0), followed by the actual Unicode õ, before my ending newline. No idea why that is leaking through to Cygwin to pick up as input. Is windows trying to beep at me to tell me my Unicode request doesn't exist in the current code page? Except that beep is Ctrl-G (U+0007). But when I switch to code page 65001, wikipedia redirects me to UTF-8. So in that code page, presumably all ALT sequences represent themselves, whether or not there is a leading 0? No, experimentation shows otherwise: shows nothing (and not the smiley face from codepage 437); while shows ^B (where ctrl-b really is code point 2). I have no idea WHAT sequence would thus give you ö. > Now you might say, why not just use codepage 437? Which is exactly what > Corinna > did say: > > http://cygwin.com/ml/cygwin/2017-03/msg00193.html Well, obviously, the code page matters to cmd; and I have no idea what alt- sequences do (or are supposed to do) under mintty. So there may STILL be some lingering craziness on what Cygwin itself should do when it recognizes an alt- sequence coming in (if cygwin translates from the current code page to Unicode, where the current code page definitely affects which character is desired);
