[ANNOUNCEMENT] Updated: libssh2_1, libssh2-devel, mingw64-{x86_64, i686}-libssh2 1.10
The following packages have been upgraded in the Cygwin distribution:
* libssh2_1 1.10
* libssh2-devel 1.10
* mingw64-x86_64-libssh21.10
* mingw64-i686-libssh2 1.10
libssh2 is a library implementing the SSH2 protocol, supporting many features.

Re: cygrunsrv + sshd + rsync = 20 times too slow -- throttled?

There are quite a few more steps to take if you want to emulate what setup does. Then again you cannot do that on a live Cygwin system unless you _really_ know what exactly it is you're doing and which packages can or cannot be touched that way. This is a downside of having only a general and not also a "technical" mailing list to discuss and diagnose "technical" issues and approaches. The suggestion was intended as a tip to ensure *complete* locally rebuilt package contents are installed, by folks who are already having issues with their installation, rebuilding Cygwin and packages, and replacing the Cygwin dll etc. and packages to diagnose those issues. So hopefully they are also aware of preremove and postinstall scripts, in packages where they are provided, and the /etc/setup/PKG.lst.gz manifests for files to be removed before installation, and provided after installation. For the latter I would expect technical folks to make use of them but leave them to Cygwin Setup programs for officially released package upgrades. [Also some of us do not have the appropriate technical background and expertise to get a Cygwin overlay mirror working reliably from the available instructions (if it was easy enough, someone would have provided a local-overlay-mirror package to do it years ago), nor systems fast enough to run Cygwin Setup for every package install. Due to Windows "improvements", my system upgraded a few years ago is just as "fast" as the 10 year old system it replaced. ;^> Cygwin Setup upgrades can take as long as Windows Update installing the latest patches. Some of my approaches, suggestions, and participation here are coloured by those limitations (also by expensive, slow, uncompetitive networks).] -- Take care.

addr = mmap (0, page_size, PROT_READ | PROT_WRITE,
MAP_PRIVATE | MAP_ANONYMOUS, -1, 0);
if (addr == MAP_FAILED)
perror ("mmap");
}
$ gcc mmap_test.c
$ ./a
mmap: Invalid argument
This happens if I use cygwin1.dll built from the current git master. But it
also happens if I build from cygwin-3_2_0-release with the recent patches
applied that make Cygwin build without error:
0e12b4939 Cygwin: C++17: register keyword is deprecated
a7340e0c0 Cygwin: dumper: fix up GCC pragma for g++ 11.2
2a212c086 Cygwin: workaround a g++ 11.2 initialization bug
9e3f1737e Cygwin: loader script: add DWARF 5 sections
bdfd2b004 Cygwin: testsuite: avoid "conflicting types" gcc warning
6fc498e2e strstr: avoid warnings
26da270b2 ldexp/ldexpf: avoid assembler warning
edce2a557 Cygwin: fix declaration of RtlInitEmptyUnicodeString
Sorry, those commit ids are wrong. They're what I got after rebasing the
master branch so that those commits come first.
[Pressed Send too soon.]
Here are the correct commits:
8169e39ab Cygwin: C++17: register keyword is deprecated
3ca80b360 Cygwin: dumper: fix up GCC pragma for g++ 11.2
bdb7991db Cygwin: workaround a g++ 11.2 initialization bug
801120c1f Cygwin: loader script: add DWARF 5 sections
d5cc66426 Cygwin: testsuite: avoid "conflicting types" gcc warning
c2fe205b5 strstr: avoid warnings
76c2c7a89 ldexp/ldexpf: avoid assembler warning
eeeb5650c Cygwin: fix declaration of RtlInitEmptyUnicodeString
So there appears to be something wrong with cygwin1.dll built with the
current build tools (gcc 11.2.0, binutils 2.37, not sure what else is
relevant).
Wait a minute...I'll bet this is related to the MEM_EXTENDED_PARAMETER
initialization problem that was dealt with in commit bdb7991db.
More data: When I run the test case under gdb, it succeeds. When I run it under
strace, I see VirtualAlloc2 in fhandler_dev_zero::mmap failing with windows
error 87.
