Broken bash command substitution
Dear list, I use Cygwin64 for a long time and everything went well. However, after one setup.exe update, the command substitution (`foo`) is broken on bash. How to reproduce: $ echo "===`echo 123`===" ===123=== $ echo "===`echo 123 | cat`===" ===123=== $ A=`echo 123`; echo "===$A===" ===123=== $ A=`echo 123 | cat`; echo "===$A===" #<-- This one breaks (returned empty string) == $ A=`echo 123 | cat`; $ echo "===$A===" ===123=== $ A=$(echo 123 | cat); echo "===$A===" == $ dash $ A=`echo 123 | cat`; echo "===$A===" #<-- Did not occur on other shells ===123=== $ exit $ ash $ A=`echo 123 | cat`; echo "===$A===" ===123=== $ exit $ ssh a-linux-server $ A=`echo 123 | cat`; echo "===$A===" #<-- Linux doesn't have problem either ===123=== $ exit This bug also occurs on another machine (win10 x64). And chere(1) is influenced by the bug and rendered unusable (ver 1.4 L613: KEY_ELEMENTS=`echo $1 | sed "s?/? ?g"`). Anyway the cygcheck.log is attached. Additionally cygcheck complains about a cygheap base mismatch. This is a new-installed windows 7 x64 and I double confirmed there's only one cygwin1.dll on my computer. 2 [main] cygcheck (2556) C:\cygwin64\bin\cygcheck.exe: *** fatal error - cygheap base mismatch detected - 0x180302408/0x22D2408. This problem is probably due to using incompatible versions of the cygwin DLL. Search for cygwin1.dll using the Windows Start->Find/Search facility and delete all but the most recent version. The most recent version *should* reside in x:\cygwin\bin, where 'x' is the drive on which you have installed the cygwin distribution. Rebooting is also suggested if you are unable to find another cygwin1.DLL. I'm not sure if it is a bug or my configuration problem, and whether it is filed or not. Please help with it.

Re: Fullscreen application with Cygwin/X in multiwindow mode

Both of the PDF viewers work fine, except when I press F11 to view a PDF fullscreen, nothing changes. Is this an inherent limitation of Cygwin/X, or a problem with my config or these particular applications? Should it be possible to make an X application fullscreen while running in multiwindow mode? The multiwindow-mode window manager doesn't support or advertise support for _NET_WM_STATE_FULLSCREEN, so this doesn't work at the moment. So, technically I guess this an application/toolkit problem, as it should notice that lack of support and e.g. grey-out the fullscreen option in the menu. But ideally this would be fixed by adding support for _NET_WM_STATE_FULLSCREEN to the WM. -- Jon Turney Volunteer Cygwin/X X Server maintainer -- 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
Re: Broken bash command substitution

You didn't specify what version of bash you are running. Since here: $ ssh a-linux-server $ A=`echo 123 | cat`; echo "===$A===" #<-- Linux doesn't have problem either ===123=== $ exit --- You know that the main shell on linux is "bash". If it didn't happen on linux, that meant it didn't happen in the bash on that linux. What version of bash was it running? Problems in bash are specific to specific versions of bash -- so their version becomes important. Using "bash --version" should tell you. If the versions are different and the later version doesn't have your problem, something may have changed to fix the problem. Also, FWIW, when I try your example on cygwin, I got: unset A; A=`echo 123 | cat`; echo "===$A===" ===123=== I.e - it seemed to work. Not that it makes a difference in your test case, but I think use of backticks has been replaced by a suggestion to use "$()", like: unset A; A=$(echo 123|cat); echo "===$A===" ===123=== I think it was thought that "$()" hilighted the subprocess more clearly as well as making it more clear that the interior text is done in a sub process.
