17db5de0ca add debug pretty-printing for sync record status flags as well 2022-06-19 16:03:44 +02:00
Oswald Buddenhagen
a49017f481 streamline pretty-printing of message flags
wrap make_flags() into fmt_flags() which returns a (struct-wrapped)
string, so the calls can be inlined into the printf statements, without
reserving buffers.

we locally force optimization, so copy elision is always done, as debug
builds would otherwise suffer a somewhat unreasonable performance hit.

6a78e2c5f6 automate enumeration of power-of-two #defines
this is a lot more legible, and makes it possible to insert values in
the middle without churn.

i didn't find a way to do this with the pre-processor, so we now have
another code generator.

we now use the $< make variable, which requires gmake on netbsd < 9.0,
and possibly other systems with an ancient make.

08a375ea07 rename nfcalloc() => nfzalloc()
the signature is like that of zalloc() (as found in the linux kernel;
not to be confused with zone allocators, etc.), not like that of
calloc().

98f4fd4586 shuffle around global variables

9356300952 convert licensing to SPDX
while at it, add/fix some licenses/copyrights/comments:
- it makes no sense to have a GPL exception in scripts
- ted did not contribute to the man page
- tst_timers is not part of the mbsync executable
- explicitly put the build system under GPL and add copyrights

f74b4e0d11 fix --debug-crash suppressing the progress display
there isn't really a reason for that; DEBUG_CRASH is quite unlike the
other DEBUG_ flags.

note that the DEBUG_*_ALL flags are not checked, because they always
come with their corresponding less verbose flag anyway.

7a0ea1f15c use correct <poll.h> header
In POSIX, poll() should be accessible using <poll.h>, although most
implementations keep <sys/poll.h> to avoid breakage. This fixes some
warnings when building on musl.

4423a932f3 add forced async mode to proxy driver
to test async operation of the syncing core while using the synchronous
maildir driver, we add a mode to the proxy driver where it queues
callback invocations to the next main loop iteration.

c3d91ae1e8 introduce new inheritance model based on C11 anonymous structs
the struct declarations got uglier, but their usage requires a lot fewer
explicit references to the parent struct (though some are added where
using the derived struct is more practical now).

we also use something i'd term "covariant members": derivatives of
store_t also reference derivatives of store_conf_t, etc., which
drastically cuts down the number of casts.
fwiw, to achieve this with "proper" inheritance in C++, we'd use
covariant getter functions which hide the still existing casts.

C11 is almost a decade old now, and compilers supported that feature
even longer than that, so i don't expect this to be a problem.

ba7b634186 make FALLTHROUGH work with qtcreator's code model
the code model inspector claims that __GNUC__ is 10, but the #if works
only with >= 4, which is plain wrong. so just handle clang explicitly.

481c12a8b3 handle CertificateFile more cleanly
properly distribute the certificates between the SSL context's trust
store and our host cert list.

as a drive-by, clean up some nasty type casts at the cost of including
a second OpenSSL header into socket.h.

d93726067d wrap jFprintf()+debug() into a macro

in the debug output, and it makes the code less noisy.

sizeof, thus defeating the intent of the packing.

e2d3b4d55b fix lots of sign conversion warnings
... by making a lot of objects unsigned, and some signed.
casts which lose precision and change the sign in one go (ssize_t and
time_t to uint on LP64) are made explicit as well.

71d7d3e6df add some ATTR_* (mostly)
mostly ATTR_PRINTFLIKE(*, 0) for functions with a va_list argument.

also, one ATTR_NORETURN and one ATTR_UNUSED, both on functions.

also, an explicit suppression for a format string stored in a variable.

df22514ced turn maildir_again() into a proper varargs function
this is mostly to work around the fact that both gcc and clang won't
accept the format string declaration (i.e., will complain with
-Wformat-nonliteral) if the *called* function does not actually take a
va_list.

on the upside, it makes one caller cleaner. yay ...

27a1935361 fix strftime() format string warning properly
the workaround for -Wformat triggered -Wformat-nonliteral in turn.
so instead go back to using pragmas and add a proper gcc version check.

this also works with clang - mostly for qt-creator's code model, which
is clang-based.

5f908b7672 attempt to improve ssl error handling (again)
the error queue may contain multiple errors, so make sure to drain it
completely. also, don't try to fall back to errno in case of
SSL_ERROR_SSL.

4cc5ad5a1a introduce driver call debugging
do that by wrapping the actual stores into proxies.

the proxy driver's code is auto-generated from function templates, some
parameters, and the declarations of the driver functions themselves.
attempts to do it with CPP macros turned out to be a nightmare.

8979ebbdf2 tolerate case changes in X-TUID header name
it is legal for an email system to simply change the case of rfc2822
headers, and at least one imap server apparently does just that.
this would lead to us not finding our own header, which is obviously not
helpful.

0e1f8f9a3f revamp console output options
- the old meaning of -V[V] was moved to -D{n|N}, as these are really
  debugging options.
- don't print the info messages by default; this can be re-enabled with
  the -V switch, and is implied by most debug options (it was really
  kind of stupid that verbose/debug operation disabled these).
- the sync algo/state debugging can be separately enabled with -Ds now.

a8b26dc4ac soft-limit peak memory usage
propagating many messages from a fast store (typically maildir or a
local IMAP server) to a slow asynchronous store could cause gigabytes of
data being buffered. avoid this by throttling fetches if the target
context reports memory usage above a configurable limit.
