Some of them were simply removed as unused (possibly some leftovers
from an older cleanup session), some were turned to haproxy/bitops.h
and a few had to be added (hlua.c and stick-table.h need standard.h
for parse_time_err; htx.h requires chunk.h but used to get it through
standard.h).
All files that were including one of the following include files have
been updated to only include haproxy/api.h or haproxy/api-t.h once instead:
- common/config.h
- common/compat.h
- common/compiler.h
- common/defaults.h
- common/initcall.h
- common/tools.h
The choice is simple: if the file only requires type definitions, it includes
api-t.h, otherwise it includes the full api.h.
In addition, in these files, explicit includes for inttypes.h and limits.h
were dropped since these are now covered by api.h and api-t.h.
No other change was performed, given that this patch is large and
affects 201 files. At least one (tools.h) was already freestanding and
didn't get the new one added.
This patch turns the double negation of 'not unlikely' into 'likely'
and then turns the negation of 'not smaller' into 'greater or equal'
in an attempt to improve readability of the condition.
[wt: this was not a bug but purposely written like this to improve code
generation on older compilers but not needed anymore as described here:
https://www.mail-archive.com/haproxy@formilux.org/msg36392.html ]
These ones are the same as the previous ones but for 64 bit values.
We're using my_ntohll() and my_htonll() from standard.h for the byte
order conversion.
These ones are the equivalent of the read_* functions. They support
writing unaligned words, possibly wrapping, in host and network order.
The write_i*() functions were not implemented since the caller can
already use the unsigned version.
This patch adds the ability to read from a wrapping memory area (ie:
buffers). The new functions are called "readv_<type>". The original
ones were renamed to start with "read_" to make the difference more
obvious between the read method and the returned type.
It's worth noting that the memory barrier in readv_bytes() is critical,
as otherwise gcc decides that it doesn't need the resulting data, but
even worse, removes the length checks in readv_u64() and happily
performs an out-of-bounds unaligned read using read_u64()! Such
"optimizations" are a bit borderline, especially when they impact
security like this...
