Re: Regression: Cygwin 3.5.1 freezes when launching several mingw processes in parallel

2024-03-04 Thread Dimitry Andric via Cygwin 
It's already been backported here: 
https://cygwin.com/cgit/newlib-cygwin/commit/?h=cygwin-3_5-branch&id=fc5e9525453fea7c27b0e13635ae54abaa0db69d

So I would guess a version 3.5.2 is very likely to appear.

Re: Regression: Cygwin 3.5.1 freezes when launching several mingw processes in parallel

2024-03-04 Thread Cedric Blancher via Cygwin 
Same here building gcc with the msnfs41client NFSv4.1 filesystem
driver (https://sourceforge.net/p/ms-nfs41-client/mailman/message/58741244/),
make -j8 and make -j128 builds now succeed again.

Is a Cygwin 3.5.x backport required?

Same here, did a bunch of make -j8 builds, and with 3.6.0-0.71.gb160b690b6ac 
they now complete without any hangs.

Thanks for the quick fix!

I will check out 3.6.0-0.71.gb160b690b6ac to see if it fixes this hang.

I'm running cygwin on baremetal on an Intel i5-750 (4 cores), with 7GB of RAM 
and with an up-to-date Windows 10.

At any given time during the RAM usage basically flat lines and there is still 
plenty of free memory left.

Thanks for the test case. I tried this test case, however,
I cannot reproduce the second problem, i.e. all 100 processes
exited normally.

To increase system load, I also tried:

#define UNICODE
#define _UNICODE

#include 
#include 

int main(int argc, char *argv[]) {
  wchar_t buf[1024];
  swprintf(buf, 1024, L"x86_64-w64-mingw32-gcc test.c -o %s", argv[1]);
  int ret = _wsystem(buf);
  if(ret != 0) printf("FOUND %d\n", ret);
}

and

#!/bin/sh
for i in $(seq 1 200); do ./a.exe $i & done

but, no error was found...

How many cpu cores and how much memory does your system have?

Re: Regression: Cygwin 3.5.1 freezes when launching several mingw processes in parallel

Hi,

Using cygwin 3.6.0-0.66.gc77a5689f7bd I was indeed unable to reproduce the 
issue.
However I'm getting a related but slightly different issue now, where a 
subprocess randomly (but quite reliably over the whole compilation process) 
fails with make -j (works fine with -j1 once again)

Luckily i was able to make a really small test-case this time:
Using MinGW 11.4.0 with the following test.c file:

#define UNICODE
#define _UNICODE

#include 
#include 

int main() {
  int ret = _wsystem(L"x86_64-w64-mingw32-gcc -dumpversion");
  if(ret != 0) printf("FOUND %d\n", ret);
}

compile using: x86_64_w64-mingw32-gcc ./test.c
and run using: for i in $(seq 1 100) ; do ./a & done

You should now be able to see at least one FOUND line among the output.

This exact behaviour happens to me everytime I try to compile the OCaml 
compiler, where a gcc subprocess fails inexplicably.

We've been getting this kind of error once in a while over the years (locally 
and in CI) but it was never reproducible to this point and it was usually fine 
if we restarted the compilation.

Kind regards,

I could reproduce the issue in Windows SandBox and might find the cause.
I'll submit a patch for this issue shortly. Thanks for the report.

I tried to reproduce this, however, make cold failed with the error:

Usage: cygpath (-d|-m|-u|-w|-t TYPE) [-f FILE] [OPTION]... NAME...
   cygpath [-c HANDLE]
   cygpath [-ADHOPSW]
   cygpath [-F ID]

Convert Unix and Windows format paths, or output system path information

Output type options:

  -d, --dos print DOS (short) form of NAMEs (C:\PROGRA~1\)
  -m, --mixed   like --windows, but with regular slashes (C:/WINNT)
  -M, --modereport on mode of file (binmode or textmode)
  -u, --unix(default) print Unix form of NAMEs (/cygdrive/c/winnt)
  -w, --windows print Windows form of NAMEs (C:\WINNT)
  -t, --type TYPE   print TYPE form: 'dos', 'mixed', 'unix', or 'windows'

Path conversion options:

  -a, --absoluteoutput absolute path
  -l, --long-name   print Windows long form of NAMEs (with -w, -m only)
  -p, --pathNAME is a PATH list (i.e., '/bin:/usr/bin')
  -U, --proc-cygdrive   Emit /proc/cygdrive path instead of cygdrive prefix
when converting Windows path to UNIX path.
  -s, --short-name  print DOS (short) form of NAMEs (with -w, -m only)
  -C, --codepage CP print DOS, Windows, or mixed pathname in Windows
codepage CP.  CP can be a numeric codepage identifier,
or one of the reserved words ANSI, OEM, or UTF8.
If this option is missing, cygpath defaults to the
character set defined by the current locale.

System information:

  -A, --allusersuse `All Users' instead of current user for -D, -O, -P
  -D, --desktop output `Desktop' directory and exit
  -H, --homerootoutput `Profiles' directory (home root) and exit
  -O, --mydocs  output `My Documents' directory and exit
  -P, --smprograms  output Start Menu `Programs' directory and exit
  -S, --sysdir  output system directory and exit
  -W, --windir  output `Windows' directory and exit
  -F, --folder ID   output special folder with numeric ID and exit
Try `cygpath --help' for more information.
** Fatal error: Cannot run cygpath -m

Any idea?

I have repro'd this problem with the exception that there was no 100% cpu 
usage.  Looks like an exception handling loop:

(2c20.4df8): Access violation - code c005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.

Regression: Cygwin 3.5.1 freezes when launching several mingw processes in parallel

Hi,

I've been using Cygwin for the past year without any issues, however today I 
upgraded to Cygwin 3.5.1 from 3.4 and noticed a consistent freeze of every 
Cygwin processes happening, and there is no way to call a new Cygwin process 
anymore (e.g. even the terminal doesn't show up) without logging off my user 
session and logging back on.

Other users and coworkers of mine have noticed this happening too the past 
couple days (first recorded break was on the 25th, with I presume, Cygwin 
3.5.0).

To reproduce this:

  *
make sure you have a fresh installed of cygwin 3.5.1
  *
install the following packages: autoconf, make, patch, curl, 
mingw64-x86_64-gcc-g++, mingw64-i686-gcc-g++
  *
curl -LO 
https://github.com/ocaml/opam/releases/download/2.2.0-beta1/opam-full-2.2.0-beta1.tar.gz
  *   tar xvf opam-full-2.2.0-beta1.tar.gz
  *   cd opam-full-2.2.0-beta1
  *   make cold

  *

At some point of the make process, one job will infinit loop (taking 100% of 
one core), while the rest of the mingw jobs will idle and never finish. After 
some time Cygwin Terminal isn't responsive anymore, and I'm not able to open 
another one or to spawn any other processes that are relying on the cygwin dll. 
I was able to observe this behaviour every time i tried consistently.

It was noticed that passing -j1 to all the calls to make in the 
shell/bootstrap-ocaml.sh script fixes this issue, so I'm guessing this is some 
kind of multicore scheduling issue.

Given it is the core of our project (the compiler) that makes the whole system 
freeze and that we were hoping to release this project soon, whose main item in 
the changelog is Windows support using Cygwin, it is somewhat vital for us for 
this to be fixed, and while we don't know much of the Cygwin internals/codebase 
we're ready to help in any ways we can.

Kind regards,
Kate
