py3: don't return the revid as unicode in hgext/convert/subversion.py I tried digging why u'' was added in first place, and I was unable to found something relevant. This might be because some API's takes unicodes, I am not sure. Differential Revision: https://phab.mercurial-scm.org/D4454

py3: make sure we pass str in os.sysconf in hgext/convert/common.py # skip-blame because just r'' prefix Differential Revision: https://phab.mercurial-scm.org/D4453

manifest: fix leak on error return from lazymanifest_filtercopy() Spotted by ASAN. free(copy->lines) and Py_DECREF(copy->pydata) are replaced by Py_XDECREF(copy), which should call lazymanifest_dealloc(). Freeing half-initialized copy->lines is safe since copy->numlines holds a valid value.

manifest: incref/decref copy->pydata to clarify 'copy' holds a reference

dirstate: use tuple interface to fix leak in pack_dirstate() Spotted by ASAN. Unlike PyTuple_GET_ITEM(), PySequence_ITEM() returns a new reference. This bug could be fixed by inserting Py_CLEAR() and Py_XDECREF() appropriately, but I think requiring a tuple object is simpler and less error-prone. The cext version is jumped to 10 since 6..9 are used in the default branch. We'll need to bump it again at merge.

xdiff: fix leak in hunk_consumer() Spotted by ASAN. Since PyList_Append() does not "steal" a reference, Py_DECREF() is always required. Perhaps, this is the largest leak in this series.

base85: fix leak on error return from b85decode() Spotted by ASAN. We don't need to initialize 'out' to NULL, but I decided to do that for clarity.
