Problem
EMSGU macro was defined as the unsigned counterpart of EMSGN. This is,
invoking emsgu instead of emsgn and having a long_u argument instead of
a long.
But, surprisingly, emsgu was not defined anywhere, which didn't result
in an error because in fact EMSGU was not used (the only point in code
printing a %lu erroneously using EMSGN instead).
Solution
- Define emsgu.
- Adapt EMSGU macro to use uint64_t instead of long_u.
reverting broad cosmetic/style change because:
- increases merge-conflicts
- increases overhead of merging upstream Vim patches
- reasons for change are ambiguous, so default to no change
By simpler cases I mean cases where the OOM error is not expected to be handled
by the caller of the function that calls `alloc`, `lalloc`, `xrealloc`,
`xmalloc`, `alloc_clear`, and `lalloc_clear`.
These are the functions that:
- Do not return an allocated buffer
- Have OOM as the only error condition
I took note of the functions that expect the caller to handle the OOM error and
will go through them to check all the callers that may be handling OOM error in
future commits.
I'm ignoring eval.c and ex_.c in this series of commits. eval.c will soon be
obsolete and I will deal with ex_.c in later PRs.
Code around `#ifdef MEM_PROFILE` was used to profile vim's memory
comsumption. It's very likely broken as new code is using malloc() and free()
directly.
In this day and age, valgrind can solve in a much reliable way what
this code was trying to do.
Because of the '$' in `if(DEFINED $ENV{VALGRIND_CHECK})` EXITFREE wasn't being
defined, so the `free_all_mem` wasn't being included or called in the resulting
binary.
This commit fixes that, and also adds includes needed for `free_all_mem`
compilation.
* removed a putenv() implementation which isn't needed anymore
* mch_getenv() and mch_setenv() are now functions in src/os/env.c
* removes direct calls to getenv() and setenv() outside of src/os/env.c
* refactored the logic of get_env_name into mch_getenvname_at_index
* added unittests for the functions in os/env.c
This is a squash of all commits sent to #81.
- Remove unused undef of __ARGS.
- Fix mch_rename declaration.
- Follow changes related to moved & extracted files.
- Properly indent function declarations of getchar.h and quickfix.c.
Continue to split misc2.c in many other files (see #209).
The only changed I made to the moved code was adding
`vim_free(ff_expand_buffer)` to `free_finfile()`. This is was needed
because `ff_expand_buffer` was moved from `misc2.c` to `file_search.c`.
