From: "Christopher M. Fuhrman" <cfuhrman@xxxxxxxxx> The current code, as is, passes control characters, such as form-feed (^L) to highlight which then passes it through to the browser. This will cause the browser to display one of the following warnings: Safari v5.1 (6534.50) & Google Chrome v13.0.782.112: This page contains the following errors: error on line 657 at column 38: PCDATA invalid Char value 12 Below is a rendering of the page up to the first error. Mozilla Firefox 3.6.19 & Mozilla Firefox 5.0: XML Parsing Error: not well-formed Location: http://path/to/git/repo/blah/blah Both errors were generated by gitweb.perl v1.7.3.4 w/ highlight 2.7 using arch/ia64/kernel/unwind.c from the Linux kernel. Strip non-printable control-characters by piping the output produced by git-cat-file(1) to col(1) as follows: git cat-file blob deadbeef314159 | col -bx | highlight <args> Note usage of the '-x' option which tells col(1) to output multiple spaces instead of tabs. Tested under OpenSuSE 11.4 & NetBSD 5.1 using perl 5.12.3 and perl 5.12.2 respectively using Safari, Firefox, and Google Chrome. Signed-off-by: Christopher M. Fuhrman <cfuhrman@xxxxxxxxx> --- Howdy, I haven't gotten any responses to my patch for a while, so I am now submitting this for general inclusion into git. Please note that this is based off the "maint" branch per Documentation/SubmittingPatches For an example of this bug in action, see: * http://git.fuhrbear.com/~cfuhrman/?p=linux/.git;a=blob;f=arch/alpha/kernel/core_titan.c;h=219bf271c0ba2e5f2d668af707df57fbbd00ccfd;hb=HEAD * http://git.fuhrbear.com/~cfuhrman/?p=linux/.git;a=blob;f=arch/ia64/kernel/unwind.c;h=fed6afa2e8a9014e65229e51e64fa4b1c13cc284;hb=HEAD WRT the col(1) command, I've verified that the binary is installed in /usr/bin on OpenSuSE, NetBSD, OpenBSD, Solaris 10, and AIX. This patch assumes that /usr/bin is in $PATH.
