sscanf doesn't handle hexadecimal floating-point input
The *scanf() functions don't handle hexadecimal floating-point input
(for example "0x1p+0" representing 1.0).
A test program:
#include
int main(void) {
int ok = 1;
float x = -1.0;
int result = sscanf("0x1p+0", "%f", &x);
const float expected_x = 1.0;
const int expected_result = 1;
printf("sscanf returned %d", result);
if (result != expected_result) {
ok = 0;
printf(" (expected %d)", expected_result);
}
printf(", x = %g", x);
if (x != expected_x) {
ok = 0;
printf(" (expected %g)", expected_x);
}
puts(ok ? ", PASSED" : ", FAILED");
}
On Cygwin, the output (compiled with gcc or clang) is:
sscanf returned 1, x = 0 (expected 1), FAILED
On Ubuntu, the output is:
sscanf returned 1, x = 1, PASSED
Looking through the newlib sources (git://sourceware.org/git/newlib-cygwin.git),
this might be related to the _WANT_IO_C99_FORMATS macro, but I haven't
looked into
the details.
The test case passes on Cygwin when compiled with i686-w64-mingw32-gcc
or x86_64-w64-mingw32-gcc.

Re: Possibly becoming a mirror

Is this acceptable or do I need to sort that first? I'm planning to do that in the near future either way. You need a public IP address with a public DNS entry pointing to that host in a domain. Some ISPs offer static IP addresses reasonably and some require a higher priced business account: https://www.broadbandgenie.co.uk/broadband/help/what-static-ip Andrews & Arnold: Free static IP as standard. Plusnet: Available on most home and business packages. £5 setup fee for home packages. Zen: Available for free on request. You may also be able to configure your router to establish a link from your ISP DHCP address to a public dynamic DNS service providing a DNS host name. Whether the name may be from a domain you control or only from theirs depends on their service offerings. Some domain registrars also offer various services including forwarding with registration. Remember you will have to initially download all 163GB of mirror files currently, rsync download any updates at least twice daily, and upload that to all comers, which could have low speeds and limits (10% of download, and remember ratings are theoretical max in Mb/s, divide by 10 for MB/s, then do an ISP speedtest and another external like speedtest.net), or require a business account, depending on your equipment and ISP: https://www.speedtest.net/global-index/united-kingdom#fixed and these numbers obviously reflect business internet services, as upload is a large fraction of download rather than typical 10%, so expect numbers that are a fraction of those listed If may be cheaper and better to consider renting a virtual cloud server. If you think you can do this from a server within an organization to which you belong, you should first talk to management, admins, and network staff. -- Take care.

realpath issue with native[strict] symlinks
Hi, When winsymlinks:native/nativestrict is used, realpath doesn't resolve the full path correctly, when a symlink to the same directory is used. Example follows. The output is: /home/user/recurse/test/d1 /home/user/recurse/test2/d1 While it should be /home/user/recurse/d1 for both. A few observations: 1. When CYGWIN is not set at all, the link is created as a junction. It works ok in cygwin, but cannot be accessed from cmd (probably because it is a file junction, and not a directory one). On this case, realpath works as expected. 2. If I create a junction using mklink /j test3 ., the issue reproduces, regardless of winsymlinks configuration. #!/bin/sh export CYGWIN=winsymlinks:nativestrict rm -rf recurse mkdir recurse cd recurse mkdir d1 ln -s . test ln -s $PWD test2 cmd ///c 'mklink /j test3 .' (cd test/d1 && realpath .) (cd test2/d1 && realpath .) (cd test3/d1 && realpath .) - Orgad -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
