* src/engine-gpg.c (build_argv): Properly check for all
arguments and allocate memory for them.

This fixes a potential buffer overflow which could be created
by using unusual and partially contradictory options.
Like offline and auto-key-locate together while

#define DIM(v) (sizeof(v)/sizeof((v)[0])) ^

in expansion of macro 'DIM' if (strlen (p) == DIM(item->keyid) - 1)
Which is a real standard way to use DIM, here the right hand side is
equivalent to sizeof but nevertheless it is correct. Yes sir, we know
C.
The format string warnings I have seen were assuming that the time
structure returns valued out of scope - but if the system is that

* The new_from_estream() function added to lang/python/src/core.py and

* Opted for the solution favouring Linux onthree main grounds:
1. Andre reported major problems with Windows as well, so the number
of potentially affected systems would vastly increase.
2. All the BSDs and OS X have spent far more time and development
work in order to accommodate the eccentricities of both Microsoft
and the GNU Project (ref. GCC), so they're more likely to be able
to cope with doing so again than the other way around.
3. If I really have to I can write a custom installer for OS X to
try this and, if it fails, to then patch the two symbol entries and
recompile from scratch. That said, I may not have to since it
actually behaved during the most recent tests for this
commit; into ten separate CPython installations and all five
supported versions (standard source installs and OS X Framework
installs for each version).

Having the file name in the verify result may lead developers to

We better don't output it at all.
The same is true for the is_mime flag but that is anyway only an
advisory and I can't see damage from a faulty one.
Note that we keep file_name in gpgme's output for ABI stability and
because some tools want to display meta information even if they are

This is a best effort feature to not output plaintext after a
decryption failure (e.g. due to no or broken authenticated
encryption). It always work when using a memory object and reading it
after the decryption but it can't work reliable when the user is
reading from the data object while the decryption process is still
running.
This is quite a large change because the data objects and the context
objects are allowed to be owned by different threads. Thus a
synchronization is needed and we do this with a global table of all
data objects to which the context objects can do soft-linking via a
unique data object serial number.

* src/gpgme-json.c (native_messaging_repl): Free request and
response after each loop.
--
If we only accept once request we should not loop. If we loop
we should do it properly.
* src/gpgme-json.c (native_messaging_repl): Ensure that the
request is NULL terminated.
--
This avoids potential memory leaks and access to unmapped memory
in case the request was not terminated.
Other request functions use es_read_line which gurantees NULL
termination.
* src/gpgme-json.c (encode_and_chunk): Try to always
return at least an error.
(process_request): Double check that it does not return NULL.
--
If process_request returns NULL the following strlen on it
would crash.
* src/gpgme-json.c (create_keylist_patterns): Reserve two
pointers more then linefeeds.
(create_keylist_patterns): Fix loop to count linebreaks.
(create_keylist_patterns): Use calloc for good measure.
--
This fixes crashes and memory corruption as cnt did not
match i.
* src/gpgme-json.c (process_request): Init res. Check for
json object before encode and chunk.
--
If json is invalid we can't read chunksize and would crash
in encode and chunk.
* src/cJSON.c: Add comments on the origin of the code.
(parse_string): Allocate an extra byte for safeness.
(cJSON_AddItemToArray): Allo ARRAY to be NULL.

* src/cJSON.c (parse_string): Correctly detect bad hex.
--
The call to parse_hex4 checks that only hex digits follow and in the
error case returns 0. However, by the time of the combined check for
an invalid value and the error PTR has already been set to the last
hex character and thus if the end-of-string or a quote character was
one of the bad hex digits the loop will miss the end of the string
which does not match with the simple buffer length allocation test at
the begin of the function.
