[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)
Pauli Virtanen p...@iki.fi added the comment: Hi, Please focus on the constraints of the consumer not mucking with the content of `Py_buffer`, and calling `bf_releasebuffer` only with data obtained from `bf_getbuffer` and only one. If we agree on this, then how to exactly to do the implementation is just a detail. The problem in the current way is that the structure sent to `bf_releasebuffer` does not contain the same data as what was filled in by `bf_getbuffer`, and since the contents are dup-ed, `bf_releasebuffer` is called multiple times with the same data. So, `bf_releasebuffer` cannot rely on (i) the data in Py_buffer being what `bf_getbuffer` put there, and (ii) getting the same Py_buffer data only once. So, `bf_releasebuffer` cannot be used to release any resources allocated in `bf_getbuffer`. For example, Numpy's PEP 3118 implementation does not define a `bf_releasebuffer` although it needs to allocate resources in each call to `bf_getbuffer`. Instead, it has to keep a track of allocated memory, and deallocate all of them on `array_dealloc`. This is a PITA, and one that could be avoided by a small change in the PEP implementation and documentation in Python. Some worrying things here: * memoryview_getbuffer() doesn't call the original object's getbuffer. This means that if I do: m = memoryview(some_object) n = memoryview(m) m.release() n ends up holding a buffer to some_object's memory, but some_object doesn't know about it and can free the pointer at any time. Good point. There are two possible solutions to this: - Keep a count of how many buffers memoryview() has exported, and do not allow memoryview.release() if some are active. In a sense, this would be more in line with the PEP: the PyMemoryViewObject would here act as an ordinary object exporting some block of memory, and not do any magic tricks. It would guarantee that the buffers it has exported stay valid. - Add additional fields to `PyMemoryViewObject` for storing new `strides`, `format`, and `shape` that override the stuff in Py_buffer. This would allow for calling `PyObject_GetBuffer` for a second time. Both would be reasonably easy to do. *** Calling PyObject_GetBuffer to get a new hold of a buffer needs some precautions, though. For example: mem = memoryview(some_object) # do some stuff mem2 = memoryview(some_object) assert mem.format == mem2.format # not guaranteed so there is some extra work `memoryview_getbuffer` could do on top of calling PyObject_GetBuffer. * same for _get_sub_buffer_index() and _get_sub_buffer_slice0(). Actually, the whole concept of non-owner memoryviews seems flawed. If the parent memoryview keeps its the memory valid as long as such sub-memoryviews exist, such concerns go away. * the fact that slicing increments the parent memoryview's refcount means that a loop like: while len(m): # do something m = m[1:] will end up keeping N chained memoryviews on the heap. Currently only the last memoryview remains alive. This has an easy solution: if the parent is a non-owner memoryview, take a reference to its obj. This then keeps only buffer-owning view on the stack. Some other things: * why do you accept the ellipsis when indexing? what is it supposed to mean? Same meaning as in Numpy. a[...] == a * please don't use #warning. Just put the TODO in a /* ... */. Sure. * please no #if PY_VERSION_HEX = 0x0300. Just make your source py3k-compatible and we'll take care of backporting it to 2.x if your patch is accepted ;) Those are just so that the backporting would be easy.

Hmm, there's a misunderstanding. bf_releasebuffer is called exactly once for each call to bf_getbuffer. Of course, bf_getbuffer can be called several times! So, `bf_releasebuffer` cannot rely on (i) the data in Py_buffer being what `bf_getbuffer` put there, Well, why should it rely on that? So, `bf_releasebuffer` cannot be used to release any resources allocated in `bf_getbuffer`. AFAICT, it can. That's what the internal pointer is for: This is for use internally by the exporting object. For example, this might be re-cast as an integer by the exporter and used to store flags about whether or not the shape, strides, and suboffsets arrays must be freed when the buffer is released. The consumer should never alter this value. (http://docs.python.org/dev/c-api/buffer.html#Py_buffer.internal) Some worrying things here: * memoryview_getbuffer() doesn't call the original object's getbuffer. This means that if I do: m = memoryview(some_object) n = memoryview(m) m.release() n ends up holding a buffer to some_object's memory, but some_object doesn't know about it and can free the pointer at any time. Good point. There are two possible solutions to this: - Keep a count of how many buffers memoryview() has exported, and do not allow memoryview.release() if some are active. Where would that count be stored? In a sense, this would be more in line with the PEP: the PyMemoryViewObject would here act as an ordinary object exporting some block of memory, and not do any magic tricks. Well, that sounds wrong to me. The memoryview doesn't export anything; the original object does. It would guarantee that the buffers it has exported stay valid. How would it, since it doesn't know the original object's semantics? - Add additional fields to `PyMemoryViewObject` for storing new `strides`, `format`, and `shape` that override the stuff in Py_buffer. This would allow for calling `PyObject_GetBuffer` for a second time. Sounds better to me :) Calling PyObject_GetBuffer to get a new hold of a buffer needs some precautions, though. For example: mem = memoryview(some_object) # do some stuff mem2 = memoryview(some_object) assert mem.format == mem2.format # not guaranteed Well, if the original object decides to change the format between two calls, then memoryview() should simply reflect that. * same for _get_sub_buffer_index() and _get_sub_buffer_slice0(). Actually, the whole concept of non-owner memoryviews seems flawed. If the parent memoryview keeps its the memory valid as long as such sub-memoryviews exist, such concerns go away. So release() wouldn't do what it claims to do? That sounds misleading. Some other things: * why do you accept the ellipsis when indexing? what is it supposed to mean? Same meaning as in Numpy. a[...] == a Yes, but why we would do that in core Python? a[...] might have a meaning in NumPy, but it has none in core Python currently.

[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)
Pauli Virtanen p...@iki.fi added the comment: Ok, good, that diversion was then avoided :) *** So, am I on the right track that there would not be many objections to clarifying the docs of Py_buffer spec by stating: - For each buffer yielded by `bf_getbuffer`, `bf_releasebuffer` is called exactly once. Each `bf_releasebuffer` call is guaranteed to get the same view-internal pointer as filled in previously by the corresponding `bf_getbuffer`. All other fields in `Py_buffer` may be modified by the consumer, and `bf_releasebuffer` may not assume they contain valid data. - The exporter of the buffer must ensure that apart from the contents of the memory pointed to by `buf`, the contents of the returned Py_buffer (format, strides, shape, etc.) remain unchanged. If the latter is not true, it will lead to no end of trouble in e.g. multithreaded programs. What about the more strict requirement: - `bf_releasebuffer` is guaranteed that all fields except `obj` are not modified? This could simplify implementation of exporters, and I suspect that MemoryViewObject is a special case, as most consumers probably would not want to make such modifications. I can try preparing an updated patch based on some combination of the above, taking into account your comments. BTW, should I take this discussion to Python-dev? So far, I kept it here, as this bug report seemed to be about general issues in the current implementation and spec. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10181 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)
Antoine Pitrou pit...@free.fr added the comment: - For each buffer yielded by `bf_getbuffer`, `bf_releasebuffer` is called exactly once. Each `bf_releasebuffer` call is guaranteed to get the same view-internal pointer as filled in previously by the corresponding `bf_getbuffer`. All other fields in `Py_buffer` may be modified by the consumer, and `bf_releasebuffer` may not assume they contain valid data. - The exporter of the buffer must ensure that apart from the contents of the memory pointed to by `buf`, the contents of the returned Py_buffer (format, strides, shape, etc.) remain unchanged. Yes! Can you write a patch that does these docs changes and also fixes the internal pointer issue? What about the more strict requirement: - `bf_releasebuffer` is guaranteed that all fields except `obj` are not modified? Well, if you manage to change the memoryview implementation for that, then fine. But I don't know how you plan to manage ownership of fields such as strides and friends. BTW, should I take this discussion to Python-dev? So far, I kept it here, as this bug report seemed to be about general issues in the current implementation and spec. I don't think you need to.

With the change above (using encodebytes instead of b64encode in encoders.py), this test, as is, fails, because there is an extra newline at the end. Extra newlines are part of base64 and should not be an issue, as a matter of fact, you obtain the original bytes when you decode, regardless of having extra newlines. It would be good to know the intent of the original author of this test. Was the intent to ensure there were no newline? If so, why? Or was the intent to simply confirm the base64 encoding conform to the standard? If the latter, my change should not be an issue.

[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)
Pauli Virtanen p...@iki.fi added the comment: Ok, here's a patch with some suggested documentation changes + the minimal changes in memoryview to make bf_releasebuffer behave as advertised. Probably shouldn't be applied as-is, though. Problems remain. Suppose `bf_getbuffer` for memoryview is implemented so that it returns a view exported by the original object (and not the memoryview). Consider an example: obj = PictureSet() # exposes a buffer, say, to pic_1 a = memoryview(obj) # points to pic_1 Here, `a` grabs a lock to pic_1. obj.choose_picture(2)# switches the exposed buffer to pic_2 b = memoryview(obj) # points to pic_2 c = memoryview(a) Here, PyObject_GetBuffer in bf_getbuffer for `a` grabs a lock to pic_2 and passes it on to `c`. The spec specifies no ways to get additional locks on pic_1. a.release() Now lock on pic_1 is released, and the buffer may be freed (also, if the handling of shape/stride arrays in memoryview is as it is now, also those are invalidated). One of the two is now true: `memoryview(a)` does not always describe the same area of memory as `a`, OR, `c` ends up with a lock on the wrong area of memory and the program hits a SEGV. [clip] In a sense, this would be more in line with the PEP: the PyMemoryViewObject would here act as an ordinary object exporting some block of memory, and not do any magic tricks. Well, that sounds wrong to me. The memoryview doesn't export anything; the original object does. Having the memoryview own the exported buffer would be a simple solution to the above issue. The alternative would be to adjust the spec so that the above type of behavior is forbidden (any buffers and the shape/stride arrays ever exported must remain valid until the last one is released). Not sure if it makes sense to do this if the only gain is a simplification in the implementation of memoryview. It would guarantee that the buffers it has exported stay valid. How would it, since it doesn't know the original object's semantics? The original object must guarantee that the buffers remain valid until released, as specified in the PEP. Of course, this requires that memoryview counts how many buffers it has exported, and allows release() only if the count is zero. -- Added file: http://bugs.python.org/file20756/buffer-interface-clarify.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10181 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Consider an example: obj = PictureSet() # exposes a buffer, say, to pic_1 a = memoryview(obj) # points to pic_1 Here, `a` grabs a lock to pic_1. obj.choose_picture(2)# switches the exposed buffer to pic_2 That's a very bad API to begin with. Anyone thinking it is reasonable to have the concept of a current element in a container should write PHP code instead. If you have individual pictures, please use individual objects. b = memoryview(obj) # points to pic_2 c = memoryview(a) Here, PyObject_GetBuffer in bf_getbuffer for `a` grabs a lock to pic_2 and passes it on to `c` So what? c will represent pic_2 anyway, so the behaviour is right. Awful certainly for the user, but that's because PictureSet implements a braindead API. , and the buffer may be freed (also, if the handling of shape/stride arrays in memoryview is as it is now, also those are invalidated). One of the two is now true: `memoryview(a)` does not always describe the same area of memory as `a`, OR, `c` ends up with a lock on the wrong area of memory and the program hits a SEGV. This all points to completely broken logic in the imaginary PictureSet class. If someone doesn't get their semantics right, it is not the buffer API's problem. bf_getbuffer and bf_releasebuffer must implement symmetric operations; perhaps that's not explicitly worded, but it seems quite obvious to me. The alternative would be to adjust the spec so that the above type of behavior is forbidden (any buffers and the shape/stride arrays ever exported must remain valid until the last one is released). Why would you adjust the spec? This just stems from common sense. If you provide a pointer to a consuming API, you have to ensure the pointer remains valid as long as the consuming API is using that pointer. Actually, that's *exactly* why there's a bf_releasebuffer method at all. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10181 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Note my comment earlier, pointing out that under those rules, dup_buffer actually does the right thing given the way it is used in the current implementation, but there's one current bug (issue 9990) where the wrong address is passed to the release buffer call - get_buffer is called with a stack address, the contents are copied to a heap address, then the heap address is used in the release_buffer call. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10181 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)
Nick Coghlan ncogh...@gmail.com added the comment: As far as the question of re-exporting the underlying view or not goes, I agree having memoryview(a) potentially refer to different underlying memory from a itself (because the source object has changed since the first view was exported) is a recipe for confusion. It is also important for ensuring memoryview slicing works correctly. From a didactic point of view, this would also have the benefit of providing a canonical example of managing exported Py_buffer structs in the CPython source code. The repeated slicing issue is definitely a concern, though. If we declare memoryview objects officially immutable, then we can avoid that by shortcutting the chaining with a typecheck on the referenced object (i.e. call GetBuffer on the source object directly if it is a memoryview, but on the memoryview we're copying otherwise) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10181 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I'm *much* happier with the rule based on malloc/free semantics where the *pointer* passed to PyObject_GetBuffer must match a single later call to PyObject_ReleaseBuffer. Agreed that Py_buffer should have been a PyObject from the start, but the PEP chose differently. We now have backwards compatibility constraints. What do we do with PyMemoryView_FromBuffer? Also, there's probably some code out there that likes to copy Py_buffers around. As far as the question of re-exporting the underlying view or not goes, I agree having memoryview(a) potentially refer to different underlying memory from a itself (because the source object has changed since the first view was exported) is a recipe for confusion. If an object changes its buffer while it's exported somewhere, it will always result in confusion for the user, regardless of how the memoryview object is implemented. All normal uses of the buffer API assume that the buffer's memory doesn't change while it's being accessed by its consumer (what would it mean to SHA1-hash or zlib-compress a changing piece of memory?).
