fixup! decoder: Fix thinko in PROTO opcode handling (#41) (#42) · 2a0ddd42

Kirill Smelkov authored Sep 10, 2018

Add a test that excersizes whether invalid protocol version is caught
and reported. Without 5c420f85 the test fails like this:

	--- FAIL: TestDecodeError (0.00s)
	    ogorek_test.go:312: "\x80\xffI1\n.": no decode error  ; got 1, <nil>

decoder: Fix thinko in PROTO opcode handling (#41) · 5c420f85

Kirill Smelkov authored Sep 05, 2018

Due to := in

	v, err := d.r.ReadByte()

newly declared err was shadowing outside err and thus even though the
code intent was to treat all protocols != 2 as ErrInvalidPickleVersion,
after leaving the switch err was always =nil and no error was reported.

Fix it by explicitly declaring v and not using := not to shadow err.

We also change the condition for supported protocol version to be in [0, 4] because:

- we already have messages in our testsuite with PROTO opcode and
  version 1, and if we don't adjust the version condition the tests will fail.

- the highest protocol version we support opcodes for is 4.
- even though the documentation for PROTO opcode says version must be >= 2,
  in practice CPython decodes pickles with PROTO and lower version just ok:

	In [18]: pickle.loads("\x80\x02I5\n.")
	Out[18]: 5

	In [19]: pickle.loads("\x80\x01I5\n.")
	Out[19]: 5

	In [20]: pickle.loads("\x80\x00I5\n.")
	Out[20]: 5

  so we don't complain about those lower versions too.

Allow to hook-in application-level logic to handle persistent references (#38) · d51cc146

Kirill Smelkov authored Jul 17, 2018

Continuing 84598fe1 (Add support for persistent references) theme let's
develop support for persistent references more: the usual situation (at
least in ZODB context, which is actually the original reason
persistent references exist) is that decode converts a reference of
(type, oid) tuple form into corresponding "ghost" object - an instance
of type, but not yet loaded with database object's data. This way
resulted object tree is created right away with types application
expects (and ZODB/py further cares to automatically load object data
when that ghost objects are accessed).

To mimic this on Go side, with current state, after decoding, one would
need to make a full reflect pass on the resulted decoded objects, find
Refs, and convert them to instances of other types, also caring to
patch pointers in other objects consistently that were pointing to such
Refs. In other words it is some work and it coincides almost 100% with
what Decoder already does by itself.

Thus, not to duplicate that work and conducting parallel with Python
world, let's add ability to configure Decoder and Encoder so that
persistent references could be handled with user-specified application
logic right in the process, and e.g. Decoder would return resulted
object with references converted to corresponding Go types.

To do so we introduce DecoderConfig and EncoderConfig - configurations
to tune decode/encode process. To maintain backward compatibility
NewDecoder and NewEncoder signatures are not adjusted and instead
NewDecoderWithConfig and NewEncoderWithConfig are introduces. We should
be sure we won't need e.g. NewDecoderWithConfigAndXXX in the future,
since from now on we could be adding fields to configuration structs
without breaking backward compatibility.

For decoding there is DecoderConfig.PersistentLoad which mimics
Unpickler.persistent_load in Python:

https://docs.python.org/3/library/pickle.html#pickle.Unpickler.persistent_load

For encoding there is EncoderConfig.PersistentRef which mimics
Pickler.persistent_id in Python:

https://docs.python.org/3/library/pickle.html#pickle.Pickler.persistent_id

( for Persistent{Load,Ref}, following suggestion from @kisielk, the
choice was made to explicitly pass in/out Ref, instead of raw
interface{} pid, because that makes the API cleaner. )

Then both Decoder and Encoder are adjusted correspondingly with tests
added.

About tests: I was contemplating to patch-in support for decoder and
encoder configurations, and handling errors, into our main test
TestDecode, but for now decided not to go that way and to put the test
as separate TestPersistentRefs.

By the way, with having configurations in place, we could start to add
other things there - e.g. the protocol version to use for Encoder.
Currently we have several places where we either don't use opcodes from
higher protocol versions (fearing to break compatibility), or instead
always use higher-version opcodes without checking we should be able to
do so by allowed protocol version.

Add support for persistent references (#37) · 84598fe1

Kirill Smelkov authored Jul 01, 2018

* Add docstrings to types exposed in public API

I was refreshing my knowled of ogórek and added them along the way.

* Add support for persistent references

Python has the mechanism for objects in one pickle to reference objects
in another pickle. This mechanism is primarily used in ZODB object
database for one object to "persistently" reference another object(*).

I needed a way to load and understand objects from a ZODB database in
Go, and hence comes this patch for ogórek that teaches it to understand
such persistent references.

Like it is already with Call and Class we add a dedicated Ref type to
represent persistent references in pickle stream.

(*) in ZODB when one object is changed, there is no need to resave
unchanged object that is referencing it because its reference stays
valid and pointing to changed object: the "persistent ID" in ZODB is
only object ID and which revision of the referenced object it points to
is implicitly follows by current transaction number view of the database.

decode: Use Decoder by pointer always · cad218c8

Kirill Smelkov authored Apr 05, 2017

Most of the functions in ogorek.go already use Decoder by pointer, but
NewDecoder() and Decoder.Decode() exceptionally used it by value.

This was probably an oversight because when Decoder struct is used by
value it is copied on every Decode call and also it is not possible to
change and retain state in between calls as all changed happen to copy
and then forgotten.

This also leads to many unnnecessary allocations, i.e. memory allocated
for stack one Decode call is not reused on next Decode call etc.

So use Decoder by pointer only. This leads to the following speedup:

name old time/op new time/op delta
Speed-4 377ns ± 0% 383ns ± 4% ~ (p=0.214 n=5+5)
Decode-4 80.4µs ± 3% 72.1µs ± 1% -10.38% (p=0.008 n=5+5)
Encode-4 16.5µs ± 1% 16.5µs ± 0% ~ (p=0.690 n=5+5)

encoder/decoder: Teach ogórek about tuple · f98f54b1

Kirill Smelkov authored Mar 07, 2017

It is true that tuples and lists are very similar, and when e.g. a
python function accepts tuple as input, and then uses only indexes
access, it can be substituted with list.

However some functions do `isinstance(..., tuple)` etc, and e.g. for a
go program which wants to produce pickle for such python programs there
is currently no way to generate pickle with tuple opcodes.

So to solve this teach ogórek about tuples:

- introduce simple Tuple type which has []interface{} as underlying
- when decoding tuple opcodes produce this Tuple instead of
  []interface{} used previously.
- when encoding encode Tuple with tuple opcodes.

Otherwise Tuple can be seen and behaves like a regular go []interface{}
slice. In fact the only difference is that runtime type of Tuple is
different from runtime type of []interface{} but otherwise both values
are the same and can be casted to each other if/when needed freely.

NOTE opReduce decoder is adjusted to always require tuple, not list,
because with e.g. cPickle:

    "c__main__\nf\n]R." -> TypeError('argument list must be a tuple', ...)
    "c__main__\nf\n)R." -> ok

( the first one uses empty list - "]", and the second one empty tuple - ")" )

So it is ok and compatible to always require args to be tuple for
reduce.

encoder: Adjust it so that decode(encode(v)) == v · 4fd6be93

Kirill Smelkov authored Mar 07, 2017

That is so that decode·encode becomes identity.

For the other way

	encode(decode(pickle)) == pickle

it is generally not possible to do, because pickle machine is almost
general machine, and it is possible to e.g. have some prefix in program
which is NOP or result of which is no longer used, use different opcodes
to build list or tuple etc.

Adjustments to encoder are:

- teach it to encode big.Int back to opLong (not some struct)
- teach it to encode Call back to opReduce (not some struct)

Tests are adjusted to verify that `decode(encode(v)) == v` holds for
all inputs in test vector.

decoder: Fix crashes found by fuzzer (#32) · da5f0342

Kirill Smelkov authored Mar 08, 2017

* decoder: Don't forget to check memo for key not there on read access

If we do not do reading from memo will return memo's zero value (= nil),
which is

a) not correct - many memo keys could be read this way, and
b) nil there on stack breaks invariants of stack containing only good
   values.

Furthermore, it can even lead to crashes on e.g. calling
reflect.TypeOf(stack.top()) in the next patch.

Anyway getting something from memo must be checked for whether it there
or not for correctness.

Noticed while working on fix for #30.

* decoder: Fix "panic: runtime error: hash of unhashable type ..."

Go specification requires that only comparable types could be used as
map keys:

    https://golang.org/ref/spec#Map_types

For map[interface{}]... this is checked at runtime, and if concrete
value used as a key is not comparable it results in runtime panic, e.g.:

    panic: runtime error: hash of unhashable type ogórek.Call

    exit status 2

so when decoding dict and friends - all places where maps are populated - we
have to check whether an object on stack we are going to use as key is suitable.

Issue #30 contains comparison of 2 ways to do such check - catch
runtime panic in exception style manner or use
reflect.TypeOf(v).Comparable(). Since reflect-way turns out to be faster

https://github.com/kisielk/og-rek/issues/30#issuecomment-283609067

and likely will become more faster in the future:

https://github.com/golang/go/issues/19361

it was decided to go the reflect way (which is also a canonical way in
go land).

So audit all places where map items are set and add appropriate checks
before them.

I've verified that if we remove any of the added checks, via so far found
crash vectors, at least one crash case will reappear in tests. This
means that all added checks are actually test covered.

Updates: #30

* decoder: Don't forget to check for odd #elements in loadDict & friends

e.g. for Dict opcode the expected stack state is

	MARK key1 obj1 key2 obj2 ... keyN objN DICT

so if in between MARK and DICT there is odd number of elements this is
an error in input data. We also used to crash on such cases, e.g.:

        "(\x88d"

        panic: runtime error: index out of range

I've audited whole decoder and regarding odd #(elements) there are only 2
places to care: loadDict and loadSetItems and crashers for all of them were
already found by fuzz testing.

Fixes #30 (for all known cases so far).

decoder: Try to provide more explicit error context on invalid data (#29) · e4e61398

This partly reverts 572d0a6a and just changes %t -> %T so that printing

Along the way I've added "pickle:" prefix to errors.

In the future maybe it would make sense to create dedicated DecodeError
which would contain position, current opcode, and error message itself.
This way error reporting would be more structured and useful for users.

decoder: Stack overflow handling fixes · 2a013587

Kirill Smelkov authored Feb 28, 2017

I was going through decoder code and noticed in many places pickle
machine stack was popped / used without checks for overflow (whether
e.g. there are elements at all).

To catch/test the bugs the following approach can be used: we take all
our decoder test input vectors, and similar to a5094338 - where we were
truncating it at tail to test how unexpected EOF is handled, we can cut
some starting prefix from input and pass it to decode.

This way if there was some instructions to prepare data and later to use
the data, in skipped form there will be only "use data" instructions and
without data on stack and proper stack overflow handling it will panic.

Fix it all over the place.

For the reference here is how added test fails without actual decoder
fixes:

encoder: More unexpected EOF handling · a5094338

Kirill Smelkov authored Feb 15, 2017

Continuing 995fce81 I've decided to rework unexpected EOF testing to run
on truncated versions of all inputs we already have. This uncovered the
following:

- if an individual op decoder returns err=io.EOF - this is unexpected
  and should be turned into io.ErrUnexpectedEOF. If we do not do it
  shows as e.g.

        ogorek_test.go:91: int: no ErrUnexpectedEOF on [:1] truncated stream: v = <nil>  err = &errors.errorString{s:"EOF"}

- there was a potential buffer overrun panic in loadString - the code
  there did not have proper check for line rest length after initial ".
  The panic looks like this:

--- FAIL: TestDecode (0.00s)
panic: runtime error: slice bounds out of range [recovered]

  and can be triggered by single-character " input.

- we also turn what was previously an "insecure string" into unexpected
  EOF. The reason here is: code could not find " in the end of the
  string. This can be for 2 reasons:

  1. EOF was reached, or
  2. EOL (end of line) was reached

  unfortunately since we are currently using bufio.Buffer.ReadLine()
  which does not indicate whether EOL was there or not and strips it
  from result, we cannot distinguish above cases and properly report
  "insecure string" in 2 case.

  However unexpected EOF even for #2 seems a bit reasonable, so I think
  the change should be ok.

This is explicitly stated in bytes.Buffer documentation and is already
