There is invalid use of sig_on()
in many places. The following is wrong:
sig_on() if condition: raise Exception sig_off()
You must put a sig_off()
before the raise
(or use try
/finally
).
I also recommend to doctest these exceptions. The doctesting framework catches such invalid use of sig_on()
.
I also don't like bare except:
statements. Be explicit and use except BaseException:
or except Exception:
instead.

Thanks. I fixed them.

All of the instances I found were for problems that we never expect to arise (out of memory errors, etc). So I don't see a reasonable way to doctest these exceptions.

I know. :) I told Julian you didn't like them, but he claimed it was okay since we raised after catching in each case. Anyway, I've changed them to except BaseException:
.
comment:20 followup: ↓ 25 Changed 7 years ago by
For the record, the Python docs say
exception BaseException
The base class for all builtin exceptions. It is not meant to be directly inherited by userdefined classes (for that, use Exception).
Nested exception blocks are generally hard to read, quadruply nested exception try/except/finally blocks even more so. Besides the usual advice of breaking long functions up into shorter ones, for the heap cleanup in the face of exceptions make sure that invalid / not yet allocated pointers are NULL. To simplify the cleanup part, free(NULL)
is a noop.
The for i from 0 <= i <= n
construct is old, Cython nowadays produces the same C code for the (preferred) Python syntax for i in range(n)
.

It is technically ok in this case. The reason I don't like except:
is that in almost all cases that I have seen, it was a mistake. If you write except BaseException:
, it shows that you probably know what you're doing and that it is not a mistake. It is also consistent with "Explicit is better than implicit" from the Zen of Python (import this
).
comment:22 Changed 7 years ago by
sig_on()
should be outside the try/finally block (if sig_on()
raises a KeyboardInterrupt
, then sig_off()
should not be called)
sig_on() try: ... finally: sig_off()

What about things like mpz_clear

I've addressed the concerns about sig_on
and the Cython for loops. I agree that the supernested try blocks are ugly, but I don't know how to rewrite it safely without this nesting.

Yes, they will and Sage will crash, or at least could. On Linux you can set _MALLOC_CHECK=3 to ensure (or have a higher probability) it will crash in such cases.

So, does anyone have suggestions on how to rewrite the ugly nested try blocks in PowComputer_flint_unram.__cinit__
? Julian and I couldn't think of a better way to do it that would never have a memory leak or a double free.

I had a look at the code and the current code actually is never going to work. The Clevel functions like fmpz_poly_init
and mpz_init
never raise exceptions. So, the try
/except
is pointless. As far as I can tell, there are two kinds of exceptions which can happen: a MemoryError
in MPIR or a KeyboardInterrupt
. In both cases, the exception will be raised by sig_on()
and none of the except
blocks are executed.
If you want to be absolutely correct, every single allocation should be wrapped individually in sig_on()
/sig_off()
. Example for 2 allocations:
sig_on() alloc1() sig_off() try: sig_on() alloc2() sig_off() except BaseException: free1() raise
But at least the very deeply nested block on this ticket is allocating extremely little memory (surely less than 1000 bytes), so why not simply
alloc1() alloc2()

You are right. I had misunderstood how sig_on
/sig_off
worked.

alloc1() alloc2()
Is this acceptable? In the unlikely case that this allocation fails because we're out of memory, then sage is going to crash right?

Well, at least the very deeply nested allocation in this branch is allocating very little memory. If that already fails, bad things are going to happen anyway.

Here are two commits; the first has the 11nested try blocks with "safe" memory handling, and the second removes them for code readability. I'm fine with either approach.
comment:35 followup: ↓ 36 Changed 6 years ago by
This comment is wrong:
While the following allocations have the potential to leak small amounts of memory when interrupted or when one of the init methods raises a MemoryError
If you don't have sig_on()
, the code cannot be interrupted (unless it's called from within sig_on()
, but that would not be a good idea). It also cannot raise a MemoryError
, since there is no sig_on()
to raise them. Instead of a MemoryError
, Sage would simply crash hard.

So the whole block of allocations should be wrapped in a single sig_on()
/sig_off()
?

In that case, memory leaks are possible and the comment would be 100% correct.
comment:38 followup: ↓ 39 Changed 6 years ago by
I see that there is some smartness added to sage_mpir_malloc/... functions in src/c_lib/memory.c, and these functions are hopefully called when mpir_init is (instead of plain malloc/...).
But as far as I now, nothing similar was done for flint, and if that's the case, a failed memory allocation would go undetected anyway (and Sage crash quite quickly with null pointer dereference or similar delicious stuff).
I just looked at flint memory allocation code (flfint_malloc/...), and a failed allocation by malloc would call the flint_memory_error function which calls abort().

That's great because (unlike MPIR which silenty ignores memory errors) an abort()
within sig_on()
yields a RuntimeError
which can safely be handled.
comment:40 Changed 6 years ago by
Why not increment the __allocated
counter after every successful allocation and use its value in __dealloc__()
to decide which objects have to be deallocated? E.g.
def __cinit__(self, ...): sig_on() self.__allocated = 0 fmpz_init(self.fmpz_ccmp); self.__allocated++ fmpz_init(self.fmpz_cval); self.__allocated++ ... fmpz_poly_init(self.poly_cconv); self.__allocated++ fmpz_poly_init(self.poly_ctm); self.__allocated++ ... sig_off() def __dealloc__(self, ...): if self.__allocated >= 1: fmpz_clear(self.fmpz_ccmp) if self.__allocated >= 2: fmpz_clear(self.fmpz_cval) ...
I hope I'm understanding the problem correctly; I'm just looking at the code and didn't follow the above discussion very closely.

Not directly, as far as I know. You can do
cdef extern from *: ctypedef int volatile_int "volatile int"
and then use volatile_int
.
comment:44 Changed 6 years ago by
Agree with the volatile being necessary so that the optimizer doesn't combine the increments into a single += n. But afaik it would still be legal for the optimizer to reorder statements as
self.__allocated++ self.__allocated++ ... self.__allocated++ fmpz_init(self.fmpz_ccmp) fmpz_init(self.fmpz_cval) ... fmpz_poly_init(self.poly_ctm)
So either mark everything that needs to be accessed inorder as volatile. Or use the usual pattern
def __cinit__(self, ...): self.fmpz_ccmp = NULL self.fmpz_cval = NULL sig_on() fmpz_init(self.fmpz_ccmp) fmpz_init(self.fmpz_cval) sig_off() def __dealloc__(self, ...): if self.fmpz_ccmp != NULL: fmpz_clear(self.fmpz_ccmp) if self.fmpz_ccval != NULL: fmpz_clear(self.fmpz_ccval)
comment:45 Changed 6 years ago by
I guess that can still be broken by creative reordering of the pointer initialization, so to be 100% safe one would need to split the setting to NULL from the fmpz_init
either by
 a compiler barrier (
asm volatile("" ::: "memory")
in gcc)  move the
fmpz_init
into__init__
 RAII (separate classes for each
fmpz_poly_t
)

Just a few technical comments (I don't plan to formally review this):
 You don't need to add
include_dirs = [SAGE_INC + '/flint']
(just addflint/
to the path to the.h
files)  You don't need to add
__richcmp__
calling_richcmp
 You don't need to add
__hash__
which just raisesTypeError
: allElement
s are now unhashable by default.  For consistency with other
.pxd
files, could you move all declarations of FLINT types tosage/libs/flint/types.pxd
?  In this block
try: padic_ctx_init(self.ctx, self.fprime, 0, prec_cap, PADIC_SERIES) except: mpz_clear(self.top_power) raise
given that padic_ctx_init
is a C function, how could it ever raise a Python exception? Moreover, I find it bad style to use except:
, you should be more explicit and catch except BaseException:
instead (the reason I say this is because most people write except:
by mistake).

Replying to jdemeyer:
 You don't need to add
include_dirs = [SAGE_INC + '/flint']
(just addflint/
to the path to the.h
files)
Fixed in ab07bc41a76f58c6063c5e7a9ab8b4add7bc4f6a.
 You don't need to add
__richcmp__
calling_richcmp
Fixed in 2a1f29345297da21ffe14c47e39faa1ac76eda5a.
 You don't need to add
__hash__
which just raisesTypeError
: allElement
s are now unhashable by default.
I actually do need this implementation to override the base class. Adressed in 2a1f29345297da21ffe14c47e39faa1ac76eda5a.
 For consistency with other
.pxd
files, could you move all declarations of FLINT types tosage/libs/flint/types.pxd
?
I believe that this has happened by now.
 In this block
try: padic_ctx_init(self.ctx, self.fprime, 0, prec_cap, PADIC_SERIES) except: mpz_clear(self.top_power) raisegiven that
padic_ctx_init
is a C function, how could it ever raise a Python exception? Moreover, I find it bad style to useexcept:
, you should be more explicit and catchexcept BaseException:
instead (the reason I say this is because most people writeexcept:
by mistake).
Both fixed in 860366d0bf36e8684c97f5bd5d3e336e79f5795d.
