This removes a bunch of unused files that would have been touched by
subsequent commits that switch to using nxt_bool_t (AKA unit6_t) in
structures.
In auto/sources we have
NXT_LIB_SRC0=" \
src/nxt_buf_filter.c \
src/nxt_job_file.c \
src/nxt_stream_module.c \
src/nxt_stream_source.c \
src/nxt_upstream_source.c \
src/nxt_http_source.c \
src/nxt_fastcgi_source.c \
src/nxt_fastcgi_record_parse.c \
\
src/nxt_mem_pool_cleanup.h \
src/nxt_mem_pool_cleanup.c \
"
None of these seem to actually be used anywhere (other than within
themselves). That variable is _not_ referenced anywhere else.
Also remove the unused related header files: src/nxt_buf_filter.h,
src/nxt_fastcgi_source.h, src/nxt_http_source.h, src/nxt_job_file.h,
src/nxt_stream_source.h and src/nxt_upstream_source.h
Also, these files do not seem to be used, no mention under auto/ or build/
src/nxt_file_cache.c
src/nxt_cache.c
src/nxt_job_file_cache.c
src/nxt_cache.h is #included in src/nxt_main.h, but AFAICT is not
actually used.
With all the above removed
$ ./congfigure --openssl --debug --tests && make -j && make -j tests &&
make libnxt
all builds.
Buildbot passes.

We had a mix of styles for declaring function-like macros:
Style A:
#define \
foo() \
do { \
... \
} while (0)
Style B:
#define foo() \
do { \
... \
} while (0)
We had a similar number of occurences of each style:
$ grep -rnI '^\w*(.*\\' | wc -l
244
$ grep -rn 'define.*(.*)' | wc -l
239
(Those regexes aren't perfect, but a very decent approximation.)
Real examples:
$ find src -type f | xargs sed -n '/^nxt_double_is_zero/,/^$/p'
nxt_double_is_zero(f) \
(fabs(f) <= FLT_EPSILON)
$ find src -type f | xargs sed -n '/define nxt_http_field_set/,/^$/p'
#define nxt_http_field_set(_field, _name, _value) \
do { \
(_field)->name_length = nxt_length(_name); \
(_field)->value_length = nxt_length(_value); \
(_field)->name = (u_char *) _name; \
(_field)->value = (u_char *) _value; \
} while (0)
I'd like to standardize on a single style for them, and IMO,
having the identifier in the same line as #define is a better
option for the following reasons:
- Programmers are used to `#define foo() ...` (readability).
- One less line of code.
- The program for finding them is really simple (see below).
function grep_ngx_func()
{
if (($# != 1)); then
>&2 echo "Usage: ${FUNCNAME[0]} <func>";
return 1;
fi;
find src -type f \
| grep '\.[ch]$' \
| xargs grep -l "$1" \
| sort \

find src -type f \
