Created attachment 423149 [details] Two patches for xdotool. Description of problem(s): The new scripting feature of F13 xdotool has introduced a couple of problems: 1. If xdotool is used in a context where stdin has been redirected (e.g., in a backend shell script fed from a pipe), xdotool is a silent no-op. 2. If xdotool is invoked with single-argument commands (e.g., 'xdotool getactivewindow') and a file happens to exist with that name (getactivewindow), xdotool assumes it should read commands from that file. Version-Release number of selected component (if applicable): xdotool-1.20100227.2679-1.fc13.i686.rpm How reproducible: 100% Steps to Reproduce problem #1: 1. echo "xdotool getactivewindow" > backend; chmod u+x backend 2. echo anything | ./backend Steps to Reproduce problem #2: 1. cp /dev/null getactivewindow 2. xdotool getactivewindow Results are the same for both problems: Actual results: No output (xdotool is a silent no-op). Expected results: The normal report of a window ID, e.g.: 37748740 Additional info: Worse yet, if file 'getactivewindow' in the example above has any contents, xdotool treats them as commands, and chaos could ensue. Possible fixes follow. They introduce some command-line incompatibility, but that is not nearly as disruptive as the current breakage of pipe-fed backends using xdotool. (The two patches mentioned below are in one attachment, with an obvious separator; Mr. Bugzilla apparently won't let me attach two files.) Problem #1 can be solved by eliminating the !isatty(0) tests in xdotool.c . That would preclude the 'xdotool < myfile' form, but it's not really needed; one can use 'xdotool - < myfile' instead. I have included a patch for this (xdotool-isatty.patch) as an attachment. Problem #2 can be solved by eliminating the stat() test in xdotool.c . That would require a different mechanism to handle shebang (#!) scripts; one possibility is to add support for a '-f script' option, and require a '-f' option on the shebang header; e.g., "#!/usr/bin/xdotool -f" (as in the old days). Then instead of 'xdotool filename' one would have to use either 'xdotool -f filename' or 'xdotool - < filename'. I have included a patch for this (xdotool-dont-read-from-command-names.patch) as an attachment. The patch context assumes the application of xdotool-isatty.patch . If fixes are not implemented, a BUGS section should be added to 'man xdotool' warning about these conditions. (The good news is that there's a man page now.) BTW, the shebang script mechanism (#!/usr/bin/xdotool) is rather inefficient in that it invokes a new process for every command in the script.
Issues like this are really much better kept in the upstream bug-tracker. Could you please file this with $UPSTREAM @ http://code.google.com/p/semicomplete/issues/list ? I could file it but then I would have to be the man in the middle for all following discussion.
> Could you please file this with $UPSTREAM @ > http://code.google.com/p/semicomplete/issues/list ? Problem #1 (which I do care about as I used xdotool as a cross-user screensaver inhibitor in Fedora 12, and now it fails) seems to had been fixed upstream (http://code.google.com/p/semicomplete/issues/detail?id=19&can=1&q=xdotool). Please, pack the fixed version.
