[Monetdb-developers] encoding of strings returned by Python client

by Mark Bucciarelli

Any chance the Python client could be modified to return strings in Unicode instead of UTF-8? Seems like a better fit for Python; for example, that's how Python's sqlite3 module behaves. An alternative approach is to expose a set_encoding method on the connection that let's you specify the encoding of all text fields returned. If backward compatibility is an issue, the latter idea seems better even though it adds a knob. Any comments? (Is the maintainer of the Python adapter active even on this list? I didn't see many Python-specific posts in the archives.) Thanks, m

[Monetdb-developers] dlclose() segfault

by Mark Bucciarelli

While learning about dlopen() and dynamic libraries, I found that calling dlclose() on libbat.so segfaults. Is this a known behavior or a symptom of some problem? Thanks, m $ cat bad.c #include <dlfcn.h> int main(void) { void *handle; char *fn = "libbat.so"; handle = dlopen(fn, RTLD_NOW); dlclose(handle); return 0; } $ gcc bad.c && ./a.out Segmentation fault (core dumped) $
