Comment 1 Fujii Hironori 2020-01-16 22:49:09 PST

Giving "" to Cwd::realpath results different result on Cygwin Perl, Windows perl, Linux perl.

perl -e 'use Cwd; print Cwd::realpath("")."\n"'

Cygwin and Windows: An error occurs. "No such file or directory"
Linux: It returns the current directory

Comment 2 Fujii Hironori 2020-01-16 22:51:32 PST

Cygwin Perl

$ perl -e 'use Cwd; print Cwd::realpath("")."\n"'
: No such file or directory at -e line 1.
$


Linux Perl

$ perl -e 'use Cwd; print Cwd::realpath("")."\n"'

  Bug 206407 – preprocess-idls.pl: CygwinPathIfNeeded should use Cygwin::win_to_posix_path instead of invoking cygpath

I hope above change would happen to solve this issue. 🤞

Comment 4 Fujii Hironori 2020-01-22 17:59:28 PST

This error still happened today.

r254954 landed Bug 206407 change.
I'll keep eyes on AppleWin EWS bots for a few days.

A similar error happened today.

> /home/buildbot/worker/Windows-EWS/build/Source/WebCore/dom/SpectreGadget.idl: No such file or directory at /home/buildbot/worker/Windows-EWS/build/Source/WebCore/bindings/scripts/preprocess-idls.pl line 101.

https://ews-build.webkit.org/#/builders/10/builds/4686

This patch (attachment 388639 [details]) actually removed SpectreGadget.idl.

Comment 6 Fujii Hironori 2020-01-23 20:47:38 PST Comment hidden (obsolete)

Oops. It's not an issue. The patch doesn't change CMakeLists.txt.

Comment 7 Fujii Hironori 2020-01-29 19:32:01 PST

I haven't observed the issue after the fix (, while observing issues of Bug 206565). Closed.
