Tom Collins 4d3a92c67c extmod/vfs_fat: Add file size as 4th element of uos.ilistdir tuple. 2018-03-12 12:26:36 +11:00
Damien George 58ebeca6a9 drivers/bus: Pull out software SPI implementation to dedicated driver.
This patch takes the software SPI implementation from extmod/machine_spi.c
and moves it to a dedicated file in drivers/bus/softspi.c.  This allows the
SPI driver to be used independently of the uPy runtime, making it a more
general component.

Damien George 21d5527edf extmod/machine_spi: Make SPI protocol structure public.
So it can be referenced directly without the need for the uPy object.

Damien George 09be031e04 extmod/vfs_fat_diskio: Use a C-stack-allocated bytearray for block buf.
This patch eliminates heap allocation in the VFS FAT disk IO layer, when
calling the underlying readblocks/writeblocks methods.  The bytearray
object that is passed to these methods is now allocated on the C stack
rather than the heap (it's only 4 words big).

This means that these methods should not retain a pointer to the buffer
object that is passed in, but this was already a restriction because the
original heap-allocated bytearray had its buffer passed by reference.

Damien George 2ad555bc76 extmod/vfs_fat: Remove declaration of mp_builtin_open_obj.
It's declared already in py/builtin.h.

Damien George eb570f47a2 extmod/vfs_fat: Make fat_vfs_open_obj wrapper public, not its function.
This patch just moves the definition of the wrapper object fat_vfs_open_obj
to the location of the definition of its function, which matches how it's
done in most other places in the code base.

Damien George 638b860066 extmod/vfs_fat: Merge remaining vfs_fat_misc.c code into vfs_fat.c.
The only function left in vfs_fat_misc.c is fat_vfs_import_stat() which
can logically go into vfs_fat.c, allowing to remove vfs_fat_misc.c.

Damien George ae4a07730a extmod/vfs_fat: Move ilistdir implementation from misc to main file.
The fat_vfs_ilistdir2() function was only used by fat_vfs_ilistdir_func()
so moving the former into the same file as the latter allows it to be
placed directly into the latter function, thus saving code size.

Damien George d9bca1f7bd extmod/modujson: Implement ujson.dump() function. 2018-02-15 11:35:42 +11:00
Ayke van Laethem 7642785881 extmod/vfs_fat_file: Implement SEEK_CUR for non-zero offset.
CPython doesn't allow SEEK_CUR with non-zero offset for files in text mode,
and uPy inherited this behaviour for both text and binary files.  It makes
sense to provide full support for SEEK_CUR of binary-mode files in uPy, and
to do this in a minimal way means also allowing to use SEEK_CUR with
non-zero offsets on text-mode files.  That seems to be a fair compromise.

Damien George 46b35356e1 extmod/modframebuf: Add 8-bit greyscale format (GS8). 2017-12-14 17:36:13 +11:00
Petr Viktorin 34247465c3 extmod/modframebuf: Add 2-bit color format (GS2_HMSB).
This format is used in 2-color LED matrices and in e-ink displays like
SSD1606.

Damien George 7df2ebbfea extmod/modussl_mbedtls: Clean up mbedtls state when error during setup.
Without this patch, if the SSL handshake fails (eg the connection was lost)
then the mbedtls state (memory) will never be freed.

Damien George ab750ee2fb extmod/modure: Convert alloca() to use new scoped allocation API. 2017-12-11 13:49:09 +11:00

Damien George 48f6990fbc extmod/modlwip: Commit TCP out data to lower layers if buffer gets full.
Dramatically improves TCP sending throughput because without an explicit
call to tcp_output() the data is only sent to the lower layers via the
lwIP slow timer which (by default) ticks every 500ms.

Damien George e511f24ddd extmod/modussl_axtls: Implement key and cert kw args to wrap_socket.
The key and cert must both be a str/bytes object in DER format.

Damien George 5e34a113ea py/runtime: Add MP_BINARY_OP_CONTAINS as reverse of MP_BINARY_OP_IN.
Before this patch MP_BINARY_OP_IN had two meanings: coming from bytecode it
meant that the args needed to be swapped, but coming from within the
runtime meant that the args were already in the correct order.  This lead
to some confusion in the code and comments stating how args were reversed.
It also lead to 2 bugs: 1) containment for a subclass of a native type
didn't work; 2) the expression "{True} in True" would illegally succeed and
return True.  In both of these cases it was because the args to
MP_BINARY_OP_IN ended up being reversed twice.

To fix these things this patch introduces MP_BINARY_OP_CONTAINS which
corresponds exactly to the __contains__ special method, and this is the
operator that built-in types should implement.  MP_BINARY_OP_IN is now only
emitted by the compiler and is converted to MP_BINARY_OP_CONTAINS by
swapping the arguments.

Damien George 12ad64bc55 extmod/vfs_fat: Mount FatFS on creation so VFS methods can be used.
It's possible to use the methods (eg ilistdir) of a VFS FatFS object
without it being mounted in the VFS itself.  This previously worked but
only because FatFS was "mounting" the filesystem automatically when any
function (eg f_opendir) was called.  But it didn't work for ports that used
synchronisation objects (_FS_REENTRANT) because they are only initialised
via a call to f_mount.  So, call f_mount explicitly when creating a new
FatFS object so that everything is set up correctly.  Then also provide a
finaliser to do the f_umount call, but only if synchronisation objects are
enabled (since otherwise the f_umount call does nothing).

Damien George 4601759bf5 py/objstr: Remove "make_qstr_if_not_already" arg from mp_obj_new_str.
This patch simplifies the str creation API to favour the common case of
creating a str object that is not forced to be interned.  To force
interning of a new str the new mp_obj_new_str_via_qstr function is added,
and should only be used if warranted.

Apart from simplifying the mp_obj_new_str function (and making it have the
same signature as mp_obj_new_bytes), this patch also reduces code size by a
bit (-16 bytes for bare-arm and roughly -40 bytes on the bare-metal archs).

Damien George 6bc55b657b extmod/vfs: Use existing qstr for forward-slash string object. 2017-11-16 13:13:24 +11:00
Christopher Cooper 7413b3ce3e extmod/moduhashlib: Enable SHA1 hashing when using "mbedtls" library.
The SHA1 hashing functionality is provided via the "axtls" library's
implementation, and hence is unavailable when the "axtls" library is not being
used.  This change provides the same SHA1 hashing functionality when using the
"mbedtls" library by using its implementation instead.

Paul Sokolovsky 1cf6d488b3 extmod/modussl_axtls: Typo fix in comment. 2017-11-02 00:16:03 +02:00
Paul Sokolovsky 0719c936fb extmod/modussl_axtls: socket_read: Handle EAGAIN.
If SSL_EAGAIN is returned (which is a feature of MicroPython's axTLS fork),
return EAGAIN.

Original axTLS returns SSL_OK both when there's no data to return to user
yet and when the underlying stream returns EAGAIN. That's not distinctive
enough, for example, original module code works well for blocking stream,
but will infinite-loop for non-blocking socket with EAGAIN. But if we fix
non-blocking case, blocking calls to .read() will return few None's initially
(while axTLS progresses thru handshake).

Using SSL_EAGAIN allows to fix non-blocking case without regressing the
blocking one.

Note that this only handles case of non-blocking reads of application data.
Initial handshake and writes still don't support non-blocking mode and must
be done in the blocking way.

Eric Poulsen 74ec52d857 extmod/modussl: Add finaliser support for ussl objects.
Per the comment found here
https://github.com/micropython/micropython-esp32/issues/209#issuecomment-339855157,
this patch adds finaliser code to prevent memory leaks from ussl objects,
which is especially useful when memory for a ussl context is allocated
outside the uPy heap.  This patch is in-line with the finaliser code found
in many modsocket implementations for various ports.

This feature is configured via MICROPY_PY_USSL_FINALISER and is disabled by
default because there may be issues using it when the ussl state *is*
allocated on the uPy heap, rather than externally.

Damien George c64eb4f8ce extmod/vfs: Replace VLA in proxy func with small, static sized array.
VLAs can be expensive on stack usage due to stack alignment requirements,
and also the fact that extra local variables are needed to track the
dynamic size of the stack.  So using fixed-size arrays when possible can
help to reduce code size and stack usage.

In this particular case, the maximum value of n_args in the VLA is 2 and so
it's more efficient to just allocate this array with a fixed size.  This
reduces code size by around 30 bytes on Thumb2 and Xtensa archs.  It also
reduces total stack usage of the function: on Thumb2 the usage with VLA is
between 40 and 48 bytes, which is reduced to 32; on Xtensa, VLA usage is
between 64 and 80 bytes, reduced to 32; on x86-64 it's at least 88 bytes
reduced to 80.

Damien George f4059dcc0c all: Use NULL instead of "" when calling mp_raise exception helpers.
This is the established way of doing it and reduces code size by a little
bit.

Damien George 9725a654bd extmod/uos_dupterm: Swallow any errors from dupterm closing the stream.
Without this the board will crash when deactivating a stream that doesn't
have a close() method (eg UART) or that raises an exception within the
method (eg user-defined function).
2017-10-19 14:10:17 +11:00
Damien George 37282f8fc1 extmod/uos_dupterm: Update uos.dupterm() and helper funcs to have index.
The uos.dupterm() signature and behaviour is updated to reflect the latest
enhancements in the docs.  It has minor backwards incompatibility in that
it no longer accepts zero arguments.

The dupterm_rx helper function is moved from esp8266 to extmod and
generalised to support multiple dupterm slots.

A port can specify multiple slots by defining the MICROPY_PY_OS_DUPTERM
config macro to an integer, being the number of slots it wants to have;
0 means to disable the dupterm feature altogether.

The unix and esp8266 ports are updated to work with the new interface and
are otherwise unchanged with respect to functionality.

Damien George a3dc1b1957 all: Remove inclusion of internal py header files.
Header files that are considered internal to the py core and should not
normally be included directly are:
    py/nlr.h - internal nlr configuration and declarations
    py/bc0.h - contains bytecode macro definitions
    py/runtime0.h - contains basic runtime enums

Instead, the top-level header files to include are one of:
    py/obj.h - includes runtime0.h and defines everything to use the
        mp_obj_t type
    py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
        and defines everything to use the general runtime support functions

Additional, specific headers (eg py/objlist.h) can be included if needed.

Paul Sokolovsky aba1f9167a extmod/modure: Add stack overflow checking when executing a regex. 2017-10-03 00:20:10 +03:00
Paul Sokolovsky c9a0b2a818 extmod/re1.5: Upgrade to v0.8.2, adds hook for stack overflow checking. 2017-10-02 21:20:47 +03:00
Paul Sokolovsky 4a314a6f63 extmod/re1.5: Update to 0.8.1.
Allow literal minus in char classes to be in trailing position, e.g. [a-c-].
(Previously, minus was allowed only at the start.)

This increases ARM Thumb2 code size by 8 bytes.
2017-09-24 10:19:24 +03:00
Damien George b02be234e1 extmod/machine_pinbase: Put PinBase singleton in ROM.
This patch also removes the empty type "pinbase_type" (which crashes if
accessed) and uses "machine_pinbase_type" instead as the type of the
PinBase singleton.

Damien George beeb7483d8 extmod/modussl_mbedtls: Allow to compile with MBEDTLS_DEBUG_C disabled.
With MBEDTLS_DEBUG_C disabled the function mbedtls_debug_set_threshold()
doesn't exist.  There's also no need to call mbedtls_ssl_conf_dbg() so a
few bytes can be saved on disabling that and not needing the mbedtls_debug
callback.
2017-09-06 17:34:45 +10:00
Damien George 4a93801c12 all: Update Makefiles and others to build with new ports/ dir layout.

Damien George 09547f0f51 extmod/modubinascii: Only include uzlib/tinf.h when it's really needed. 2017-08-31 14:10:49 +10:00
Damien George 71c9cfb028 all: Convert remaining "mp_uint_t n_args" to "size_t n_args".
This is to have consistency across the whole repository.
2017-08-30 10:59:58 +10:00
Damien George 58321dd985 all: Convert mp_uint_t to mp_unary_op_t/mp_binary_op_t where appropriate
The unary-op/binary-op enums are already defined, and there are no
arithmetic tricks used with these types, so it makes sense to use the
correct enum type for arguments that take these values.  It also reduces
code size quite a bit for nan-boxing builds.
2017-08-29 13:16:30 +10:00
Damien George 1c6b442d32 extmod/modubinascii: Don't post-increment variable that won't be used. 2017-08-21 22:05:39 +10:00
Damien George 4c736ea8fc extmod,unix: For uos.stat interpret st_size member as an unsigned int.
This prevents large files (eg larger than 2gb on a 32-bit arch) from
showing up as having a negative size.  Fixes issue #3227.
2017-08-21 20:47:22 +10:00
Alex Robbins c89254fd0f extmod/modubinascii: Rewrite mod_binascii_a2b_base64.
This implementation ignores invalid characters in the input. This allows
it to decode the output of b2a_base64, and also mimics the behavior of
CPython.
2017-08-17 09:25:51 +03:00
Eric Poulsen d5191edf7f extmod/modussl_mbedtls.c: Add ussl.getpeercert() method.
Behaviour is as per CPython but only the binary form is implemented here.
A test is included.
2017-08-16 15:01:00 +10:00
Javier Candeira 35a1fea90b all: Raise exceptions via mp_raise_XXX
- Changed: ValueError, TypeError, NotImplementedError
  - OSError invocations unchanged, because the corresponding utility
    function takes ints, not strings like the long form invocation.
  - OverflowError, IndexError and RuntimeError etc. not changed for now
    until we decide whether to add new utility functions.
2017-08-13 22:52:33 +10:00
Damien George 0f12082f5b py,extmod,stmhal: Use "static inline" for funcs that should be inline.
"STATIC inline" can expand to "inline" if STATIC is defined to nothing, and
this case can lead to link errors.
2017-08-02 13:42:34 +10:00
Paul Sokolovsky ee04525097 extmod/modlwip: Implement setsockopt(IP_ADD_MEMBERSHIP).
Allows to join multicast groups.
2017-07-31 22:38:37 +03:00
Alexander Steffen 55f33240f3 all: Use the name MicroPython consistently in comments
There were several different spellings of MicroPython present in comments,
when there should be only one.

Damien George bbced3b4bb extmod: Use MP_ROM_INT for int values in an mp_rom_map_elem_t. 2017-07-31 13:00:34 +10:00
