One function prototype makes reference to struct mworker_proc which was
not defined there but in global.h instead. This definition, along with
the PROC_O_* fields were moved to mworker-t.h instead.
The file mostly contained struct definitions but there was also a
variable export. Most of the stuff currently lies in checks.h and
should definitely move here!
The STATS_DEFAULT_REALM and STATS_DEFAULT_URI were moved to defaults.h.
It was required to include types/pattern.h and types/sample.h since they
are mentioned in function prototypes.
It would be wise to merge this with uri_auth.h later.
List.h was missing for LIST_ADDQ(). A few unneeded includes of action.h
were removed from certain files.
This one still relies on applet.h and stick-table.h.
A few includes had to be added, namely list-t.h in the type file and
types/proxy.h in the proto file. actions.h was including http-htx.h
but didn't need it so it was dropped.
The sink files could be moved with almost no change at since they
didn't rely on anything fancy. ssize_t required sys/types.h and
thread.h was needed for the locks.
A few includes were missing in each file. A definition of
struct polled_mask was moved to fd-t.h. The MAX_POLLERS macro was
moved to defaults.h
Stdio used to be silently inherited from whatever path but it's needed
for list_pollers() which takes a FILE* and which can thus not be
forward-declared.
And also rename standard.c to tools.c. The original split between
tools.h and standard.h dates from version 1.3-dev and was mostly an
accident. This patch moves the files back to what they were expected
to be, and takes care of not changing anything else. However this
time tools.h was split between functions and types, because it contains
a small number of commonly used macros and structures (e.g. name_desc)
which in turn cause the massive list of includes of tools.h to conflict
with the callers.
They remain the ugliest files of the whole project and definitely need
to be cleaned and split apart. A few types are defined there only for
functions provided there, and some parts are even OS-specific and should
move somewhere else, such as the symbol resolution code.
The protocol.h files are pretty low in the dependency and (sadly) used
by some files from common/. Almost nothing was changed except lifting a
few comments.
Most of the file was a large set of HTX elements manipulation functions
and few types, so splitting them allowed to further reduce dependencies
and shrink the build time. Doing so revealed that a few files (h2.c,
mux_pt.c) needed haproxy/buf.h and were previously getting it through
htx.h. They were fixed.
The file was moved as-is. There was a wrong dependency on dynbuf.h
instead of buf.h which was addressed. There was no benefit to
splitting this between types and functions.
Regex are essentially included for myregex_t but it turns out that
several of the C files didn't include it directly, relying on the
one included by their own .h. This has been cleanly addressed so
that only the type is included by H files which need it, and adding
the missing includes for the other ones.
The pretty confusing "buffer.h" was in fact not the place to look for
the definition of "struct buffer" but the one responsible for dynamic
buffer allocation. As such it defines the struct buffer_wait and the
few functions to allocate a buffer or wait for one.
This patch moves it renaming it to dynbuf.h. The type definition was
moved to its own file since it's included in a number of other structs.
Doing this cleanup revealed that a significant number of files used to
rely on this one to inherit struct buffer through it but didn't need
anything from this file at all.
This moves types/activity.h to haproxy/activity-t.h and
proto/activity.h to haproxy/activity.h.
The macros defining the bit field values for the profiling variable
were moved to the type file to be more future-proof.
Now the file is ready to be stored into its final destination. A few
minor reorderings were performed to keep the file properly organized,
making the various sections more visible (cache & lockless).
In addition and to stay consistent, memory.c was renamed to pool.c.
types/freq_ctr.h was moved to haproxy/freq_ctr-t.h and proto/freq_ctr.h
was moved to haproxy/freq_ctr.h. Files were updated accordingly, no other
change was applied.
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).
This one is included almost everywhere and used to rely on a few other
.h that are not needed (unistd, stdlib, standard.h). It could possibly
make sense to split it into multiple parts to distinguish operations
performed on timers and the internal time accounting, but at this point
it does not appear much important.
This splits the hathreads.h file into types+macros and functions. Given
that most users of this file used to include it only to get the definition
of THREAD_LOCAL and MAXTHREADS, the bare minimum was placed into thread-t.h
(i.e. types and macros).
All the thread management was left to haproxy/thread.h. It's worth noting
the drop of the trailing "s" in the name, to remove the permanent confusion
that arises between this one and the system implementation (no "s") and the
makefile's option (no "s").
For consistency, src/hathreads.c was also renamed thread.c.
A number of files were updated to only include thread-t which is the one
they really needed.
Some future improvements are possible like replacing empty inlined
functions with macros for the thread-less case, as building at -O0 disables
inlining and causes these ones to be emitted. But this really is cosmetic.
A few files were including it while not needing it (anymore). Some
only required access to the atomic ops and got haproxy/atomic.h in
exchange. Others didn't need it at all. A significant number of
files still include it only for THREAD_LOCAL definition.
Half of the users of this include only need the type definitions and
not the manipulation macros nor the inline functions. Moves the various
types into mini-clist-t.h makes the files cleaner. The other one had all
its includes grouped at the top. A few files continued to reference it
without using it and were cleaned.
In addition it was about time that we'd rename that file, it's not
"mini" anymore and contains a bit more than just circular lists.
File buf.h is one common cause of pain in the dependencies. Many files in
the code need it to get the struct buffer definition, and a few also need
the inlined functions to manipulate a buffer, but the file used to depend
on a long chain only for BUG_ON() (addressed by last commit).
Now buf.h is split into buf-t.h which only contains the type definitions,
and buf.h for all inlined functions. Callers who don't care can continue
to use buf.h but files in types/ must only use buf-t.h. sys/types.h had
to be added to buf.h to get ssize_t as used by b_move(). It's worth noting
that ssize_t is only supposed to be a size_t supporting -1, so b_move()
ought to be rethought regarding this.
The files were moved to haproxy/ and all their users were updated
accordingly. A dependency issue was addressed on fcgi whose C file didn't
include buf.h.
This one used to be stored into debug.h but the debug tools got larger
and require a lot of other includes, which can't use BUG_ON() anymore
because of this. It does not make sense and instead this macro should
be placed into the lower includes and given its omnipresence, the best
solution is to create a new bug.h with the few surrounding macros needed
to trigger bugs and place assertions anywhere.
Another benefit is that it won't be required to add include <debug.h>
anymore to use BUG_ON, it will automatically be covered by api.h. No
less than 32 occurrences were dropped.
The FSM_PRINTF macro was dropped since not used at all anymore (probably
since 1.6 or so).
Fortunately that file wasn't made dependent upon haproxy since it was
integrated, better isolate it before it's too late. Its dependency on
api.h was the result of the change from config.h, which in turn wasn't
correct. It was changed back to stddef.h for size_t and sys/types.h for
ssize_t. The recently added reference to MAX() was changed as it was
placed only to avoid a zero length in the non-free-standing version and
was causing a build warning in the hpack encoder.
This file is to openssl what compat.h is to the libc, so it makes sense
to move it to haproxy/. It could almost be part of api.h but given the
amount of openssl stuff that gets loaded I fear it could increase the
build time.
Note that this file contains lots of inlined functions. But since it
does not depend on anything else in haproxy, it remains safe to keep
all that together.
There is one "template.h" per include subdirectory to show how to create
a new file but in practice nobody knows they're here so they're useless.
Let's simply remove them.
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.
