rillig | make: in cleanup mode, initialize freshly allocated memory
This helps during debugging.

rillig | make: use a common style for unexpected error messages
In enomem, report the actual error instead of a fixed ENOMEM.

rillig | make: rename local variable in bmake_malloc
The length of a string does not include the trailing '\0'.
No binary change.

rillig | make(1): remove do-not-format markers from comments
These markers had been used inconsistently. Furthermore the source code had not been formatted automatically before 2020 at all, otherwise there wouldn't have been any trailing whitespace left.

rillig | make(1): remove duplicate code from bmake_strdup
Inlining is the job of the compiler, not of humans.

rillig | make(1): revert previous commit
It had accidentally reverted all the work from the past few days.

rillig | make(1): fix double-free bug in -DCLEANUP mode (since 2020-10-02)
The bug had been introduced with dir.c 1.155 on 2020-10-02 22:20:25. In that commit, openDirectories was replaced with a combination of a list with a hash table, for more efficient lookup by name.
Upon cleanup, OpenDirs_Done is called, which in turn called Dir_ClearPath. Dir_ClearPath takes full ownership of the given list and empties it. This was no problem before since afterwards the list was empty and calling Lst_Free just frees the remaining list pointer.
With OpenDirs, this list was combined with a hash table, and the hash table contains the list nodes, assuming that the OpenDirs functions have full ownership of both the list and the hash table. This assumption was generally correct, except for the one moment during cleanup where full ownership of the list was passed to Dir_ClearPath, while the hash table still contained pointers to the (now freed) list nodes. This by itself was not a problem since the hash table would be freed afterwards. But as part of Dir_ClearPath, OpenDirs_Remove was called, which looked up the freed directory by name and now found the freed list node, trying to free it again. Boom.
Fixed by replacing the call to Dir_ClearPath with code that only frees the directories, without giving up control over the list.

rillig | make(1): remove redundant function prototypes

rillig | make(1): clean up RCSID blocks
These blocks mostly consisted of redundant structure, following the same #ifndef pattern over and over, with only minimal variation.
It's easier to maintain if the common structure is only written once and encapsulated in a macro.
To avoid "defined but unused" warnings from GCC in the case where MAKE_NATIVE is not defined, I had to add volatile. Adding MAKE_ATTR_UNUSED alone would not preserve the rcsid variable in the resulting binary.

rillig | make(1): add bmake_strsedup for duplicating a substring

rillig | make(1): remove unreached code from bmake_strndup
The "at most" branch was never taken since all call sites in var.c only ever need a substring, and the target buffer is not limited. Therefore rename the function and make it simpler.
It's ok that bmake_strldup is defined as estrndup in case of USE_EMALLOC since that function's implementation is compatible to the "copy exactly", it just contains some extra null checks that will never match since the variable values cannot (well, or should not) contain null bytes. Theoretically they can, but the behavior then depends on the exact implementation and is unreliable, therefore nobody does this. After all, Makefiles are used for text processing, not for binary data.

rillig | make(1): remove unnecessary test from bmake_strndup
The passed memory is never NULL.
|
1.13 |
| 12-Aug-2020 |
rillig | make(1): in bmake_strndup, only scan the relevant part of the string
Just in case the given str is not really a string.
The POSIX 2018 documentation on strndup does not specify as clearly as possible whether s has to be a string or whether raw memory is acceptable as well. It only indirectly calls the s parameter of strndup a string.

joerg | Replace __dead, __unused and the various printf format attributes with versions prefixed by MAKE_ATTR_* to avoid modifying the implementation namespace. Make sure they are available in all places using nonints.h to fix bootstrap on Linux.
