[MXNET-953] Fix oob memory read (v1.3.x) / #13118
Simple bugfix addressing an out-of-bounds memory read.
[MXNET-969] Fix buffer overflow in RNNOp (v1.3.x) / #13119
This fixes an buffer overflow detected by ASAN.
CudnnFind() usage improvements (v1.3.x) / #13123
This PR improves the MXNet's use of cudnnFind() to address a few issues:
This PR addresses these issues, providing the following benefits:
Set correct update on kvstore flag in dist_device_sync mode (v1.3.x) / #13121
Fix 1st part of the issue - #12713 In dist mode, update_on_kvstore was getting overridden based on async/sparse weight, grad only. In this fix we handle - "dist_device_sync" and not ignoring kvstore_params i.e, kvstore_params['update_on_kvstore'] value. Add test case for the same.

[MXNET-922] Fix memleak in profiler (v1.3.x) / #13120
Fix a memleak reported locally by ASAN during a normal inference test.
Fix lazy record io when used with dataloader and multi_worker > 0 (v1.3.x) / #13124
Fixes multi_worker data loader when record file is used. The MXRecordIO instance needs to require a new file handler after fork to be safely manipulated simultaneously.
This fix also safely voids the previous temporary fixes #12093 #11370.
fixed symbols naming in RNNCell, LSTMCell, GRUCell (v1.3.x) / #13158
This fixes #12783, by assigning all nodes in hybrid_forward a unique name. Some operations were in fact performed without attaching the appropriate (time) prefix to the name, which makes serialized graphs non-deserializable.
Fixed __setattr__ method of _MXClassPropertyMetaClass (v1.3.x) / #13157
Fixed __setattr__ method
allow foreach on input with 0 length (v1.3.x) / #13151
Fix #12470. With this change, outs shape can be inferred correctly.
Infer dtype in SymbolBlock import from input symbol (v1.3.x) / #13117
Fix for the issue - #11849
Currently, Gluon symbol block cannot import any symbol with type other than fp32. All the parameters are created as FP32 leading to failure in importing the params when it is of type fp16, fp64 etc,
In this PR, we infer the type of the symbol being imported and create the Symbol Block Parameters with that inferred type.
Added the tests
Document the newly added env variable (v1.3.x) / #13156
Document the env variable: MXNET_ENFORCE_DETERMINISM added in PR: #12992
fix broken links (v1.3.x) / #13155
This PR fixes broken links on the website.
fix broken Python IO API docs (v1.3.x) / #13154
Fixes #12854: Data Iterators documentation is broken
This PR manually specifies members of the IO module so that the docs will render as expected. This is workaround in the docs to deal with a bug introduced in the Python code/structure since v1.3.0. See the comments for more info.
This PR also fixes another issue that may or may not be related. Cross references to same-named entities like name, shape, or type are confusing Sphinx and it seems to just link to whatever it last dealt with that has the same name, and not the current module. To fix this you have to be very specific. Don't use type, use np.type if that's what you want. Otherwise you might end up with mxnet.kvstore.KVStore.type. This is a known Sphinx issue, so it might be something we have to deal with for the time being.
This is important for any future modules - that they recognize this issue and make efforts to map the params and other elements.
add/update infer_range docs (v1.3.x) / #13153
This PR adds or updates the docs for the infer_range feature.
Clarifies the param in the C op docs Clarifies the param in the the Scala symbol docs Adds the param for the the Scala ndarray docs Adds the param for the Python symbol docs Adds the param for the Python ndarray docs
The test test_operator.test_dropout has issues and has been disabled on the branch:
