Revision 89a70b80ebabd237bb407f9321f24677f4f1d16d authored by Johannes Schindelin on 03 January 2018, 16:54:54 UTC, committed by Junio C Hamano on 03 January 2018, 23:55:50 UTC
When cleaning up files in the $HOME directory, it really makes sense to quote the path, especially in Git's test suite, where the HOME directory is *guaranteed* to contain spaces in its name. It would appear that those two tests pass even without cleaning up the files, but really more by pure chance than by design (the cleanup seems not actually to be necessary). However, if anybody would have a left-over `trash/` directory in Git's `t/` directory, these tests would fail, because they would all of a sudden try to delete that directory, but without the `-r` (recursive) flag. That is how this issue was found. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Reviewed-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

/*
* alloc.c - specialized allocator for internal objects
*
* Copyright (C) 2006 Linus Torvalds
*
* The standard malloc/free wastes too much space for objects, partly because
* it maintains all the allocation infrastructure (which isn't needed, since
* we never free an object descriptor anyway), but even more because it ends
* up with maximal alignment because it doesn't know what the object alignment
* for the new allocation is.
