remove doubled words, e.g., s/to to/to/, and fix related typos

2011-04-13T18:59:11Z

I found that some doubled words had snuck back into projects from which I'd already removed them, so now there's a "syntax-check" makefile rule in gnulib to help prevent recurrence. Running the command below spotted a few in git, too: git ls-files | xargs perl -0777 -n \ -e 'while (/\b(then?|[iao]n|i[fst]|but|f?or|at|and|[dt])\s+\1\b/gims)' \ -e '{$n=($` =~ tr/\n/\n/ + 1); ($v=$&)=~s/\n/\\n/g;' \ -e 'print "$ARGV:$n:$v\n"}' Signed-off-by: Jim Meyering Signed-off-by: Junio C Hamano

Fix warnings in nedmalloc when compiling with GCC 4.4.0

2009-06-08T16:43:37Z

Nedmalloc's source code has a cute #define construct to avoid inserting an if() statement, because that might interact badly with enclosing if() statements. However, GCC > 4 complains with a "warning: value computed is not used". So we cast the result to "void". GCC also does not understand the Visual C++ specific pragmas, so we need to disable them for MinGW. We need to include malloc.h on Windows even if we happen to compile the stuff as a MinGW program. Otherwise the function declaration of alloca() is missing. Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano

Add custom memory allocator to MinGW and MacOS builds

2009-06-01T07:27:39Z

The standard allocator on Windows is pretty bad prior to Windows Vista, and nedmalloc is better than the modified dlmalloc provided with newer versions of the MinGW libc. NedMalloc stats in Git ---------------------- All results are the best result out of 3 runs. The benchmarks have been done on different hardware, so the repack times are not comparable. These benchmarks are all based on 'git repack -adf' on the Linux kernel.
