From ce83eadd9a2c63db6263df91933da1b1b865d26a Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Wed, 8 Mar 2017 16:43:40 +0100 Subject: real_pathdup(): fix callsites that wanted it to die on error In 4ac9006f832 (real_path: have callers use real_pathdup and strbuf_realpath, 2016-12-12), we changed the xstrdup(real_path()) pattern to use real_pathdup() directly. The problem with this change is that real_path() calls strbuf_realpath() with die_on_error = 1 while real_pathdup() calls it with die_on_error = 0. Meaning that in cases where real_path() causes Git to die() with an error message, real_pathdup() is silent and returns NULL instead. The callers, however, are ill-prepared for that change, as they expect the return value to be non-NULL (and otherwise the function died with an appropriate error message). Fix this by extending real_pathdup()'s signature to accept the die_on_error flag and simply pass it through to strbuf_realpath(), and then adjust all callers after a careful audit whether they would handle NULLs well.
