Known bugs and suggested enhancements in libpng-1.0.7
|

|

1. April 24, 2000 -- BUG -- binary incompatibility
|
||||
|
||||
Libpng-1.0.6 is binary incompatible with old applications that
|
||||
allocate the png_struct and png_info structures themselves instead
|
||||
of using png_create_*(). They do not allocate enough space for
|
||||
the structures because they have an incorrect notion of
|
||||
sizeof(png_struct) and sizeof(png_info). Although such applications
|
||||
should be considered broken rather than considering libpng to be broken,
|
||||
they are numerous and include products of the PNG group, such
|
||||
as gif2png and pnmtopng-2.36 (pnmtopng-2.37 is OK), so libpng will
|
||||
be fixed in version 1.0.7 to work around this problem.
|
||||
|
||||
Applications that use png_create_*() instead of png_ptr=malloc(...)
|
||||
are immune to this problem.
|
||||
|
||||
STATUS: Fixed in libpng-1.0.6ad, libpng-1.0.6j, and patch-d
|
||||
which are currently being tested by the PNG group.
|
||||
The fix necessarily reintroduces a binary incompatibility with any
|
||||
application that makes direct access to the png_info and
|
||||
png_struct members that deal with the pCAL chunk, palette_lookup,
|
||||
dither_index, time_buffer, or weighted filtering, i.e., any members
|
||||
coming after the new "free_me" member of either structure. It
|
||||
is believed that applications affected by this reintroduced binary
|
||||
incompatibility are rare (none are known to the PNG group). An
|
||||
effective workaround for this and the next bug is to recompile the
|
||||
old applications with the installed version of libpng.
|
||||
|
||||
2. April 23, 2000 -- BUG -- binary incompatibility
|
||||
|
||||
Libpng-1.0.6 introduced binary incompatibility for applications that
|
||||
make direct access to members of the png_struct and png_info structures,
|
||||
due to the insertion of the free_me member ahead of some previously
|
||||
existing members.
|
||||
|
||||
Applications that use png_set_*(), png_get_*() are immune to this
|
||||
problem, but people are still to this day writing applications that
|
||||
make ill-advised direct access to members of the png_struct and
|
||||
png_info structures, so libpng-1.0.6 will be patched to work around
|
||||
this problem.
|
||||
|
||||
STATUS: Fixed in libpng-1.0.6j and patch-d, which are currently being
|
||||
tested by the PNG group. Users can work around the problem without
|
||||
patching libpng by recompiling their applications.
|
||||
|
||||
3. April 15, 2000 -- BUG -- pnggccrd.c
|
||||
|
||||
If PNG_NO_GLOBAL_ARRAYS is defined, pnggccrd.c will not compile.
|
||||
|
||||
STATUS: Fixed in libpng-1.0.6g
|
||||
|
||||
4. April 1, 2000 -- BUG
|
||||
|
||||
Under some circumstances old applications that make direct access to
|
||||
the info_ptr->text and its members might free the same memory that
|
||||
is also free'ed by libpng during the png_destroy_struct process.
|
||||
|
||||
Fixed in libpng-1.0.6-patch-c and libpng-1.0.6d. The PNG_FREE_TEXT flag
|
||||
bit in info_ptr->free_me is now checked to make sure libpng is responsible
|
||||
for freeing the memory.

||||

||||
5. April 1, 2000 -- BUG

||||

||||

function is used instead.

||||
8. March 22, 2000 -- BUG
|
||||
|
||||
The length of the iCCP chunk data is calculated incorrectly; because
|
||||
it can contain zeroes, strlen() doesn't work.

Microsoft Developer Studio Build File, Format Version 6.00 for VisualPng
|

------------------------------------------------------------------------
|

||||
Copyright 2000, Willem van Schaik. For conditions of distribution and
|
||||
use, see the copyright/license/disclaimer notice in png.h
|
||||
|
||||
As a PNG .dll demo VisualPng is finished. More features would only hinder
|
||||
the program's objective. However, further extensions (like support for other
|
||||
graphics formats) are in development. To get these, or for pre-compiled
|
||||
binaries, go to "http://www.schaik.com/png/visualpng.html".
|
||||
|
||||
------------------------------------------------------------------------
|
||||
|
||||
Assumes that
|
||||
|
||||
libpng DLLs and LIBs are in ..\..\msvc\win32\libpng
|
||||
zlib DLLs and LIBs are in ..\..\msvc\win32\zlib
|
||||
libpng header files are in ..\..\..\libpng
|
||||
zlib header files are in ..\..\..\zlib
|
||||
the pngsuite images are in ..\pngsuite
|
||||
|
||||
To build:
|
||||
|
||||
1) On the main menu Select "Build|Set Active configuration".
|
||||
Choose the configuration that corresponds to the library you want to test.
|
||||
This library must have been built using the libpng MS project located in
|
||||
the "..\..\mscv" subdirectory.
|
||||
|
||||
2) Select "Build|Clean"
|
||||
|
||||
3) Select "Build|Rebuild All"
|
||||
|
||||
4) After compiling and linking VisualPng will be started to view an image
|
||||
from the PngSuite directory. Press Ctrl-N (and Ctrl-V) for other images.
|
||||
|
||||
|
||||
To install:
|
||||
|
||||
When distributing VisualPng (or a further development) the following options
|
||||
are available:
|
||||
|
||||
1) Build the program with the configuration "Win32 LIB" and you only need to
|
||||
include the executable from the ./lib directory in your distribution.
|
||||
|
||||
2) Build the program with the configuration "Win32 DLL" and you need to put
|
||||
in your distribution the executable from the ./dll directory and the dll's
|
||||
libpng1.dll, zlib.dll and msvcrt.dll. These need to be in the user's PATH.

|

Adam M. Costello <amc@cs.berkeley.edu>
|
||||
|
||||
An interface for exception-handling in ANSI C, developed jointly with
|
||||
Cosmin Truta <cosmin@cs.toronto.edu>.
|
||||
|
||||
Copyright (c) 2000 Adam M. Costello and Cosmin Truta. Everyone
|
||||
is hereby granted permission to do whatever they like with this
|
||||
file, provided that if they modify it they take reasonable steps to
|
||||
avoid confusing or misleading people about the authors, version,
|
||||
and terms of use of the derived file. The copyright holders make
|
||||
no guarantees about the correctness of this file, and are not
|
||||
responsible for any damage resulting from its use.
|
||||
|
||||
If this interface is used by multiple .c files, they shouldn't include
|
||||
this header file directly. Instead, create a wrapper header file that
|
||||
includes this header file and then invokes the define_exception_type
|
||||
macro (see below), and let your .c files include that header file.
|
||||
|
||||
The interface consists of one type, one well-known name, and six macros.
|
||||
|
||||
|
||||
define_exception_type(type_name);
|
||||
|
||||
This macro is used like an external declaration. It specifies
|
||||
the type of object that gets copied from the exception thrower to
|
||||
the exception catcher. The type_name can be any type that can be
|
||||
assigned to, that is, a non-constant arithmetic type, struct, union,
|
||||
or pointer. Examples:
|
||||
|
||||
define_exception_type(int);
|
||||
|
||||
enum exception { out_of_memory, bad_arguments, disk_full };
|
||||
define_exception_type(enum exception);
|
||||
|
||||
struct exception { int code; const char *msg; };
|
||||
define_exception_type(struct exception);
|
||||
|
||||
|
||||
struct exception_context;
|
||||
|
||||
This type may be used after the define_exception_type() macro has
|
||||
been invoked. A struct exception_context must be known to both
|
||||
the thrower and the catcher. It is expected that there be one
|
||||
context for each thread that uses exceptions. It would certainly
|
||||
be dangerous for multiple threads to access the same context.
|
||||
One thread can use multiple contexts, but that is likely to be
|
||||
confusing and not typically useful. The application can allocate
|
||||
this structure in any way it pleases--automatic, static, or dynamic.
|
||||
The application programmer should pretend not to know the structure
|
||||
members, which are subject to change.
|
||||
|
||||
|
||||
struct exception_context *the_exception_context;
|
||||
|
||||
The Try/Catch and Throw statements (described below) implicitly
|
||||
refer to a context, using the name the_exception_context. It is
|
||||
the application's responsibility to make sure that this name yields
|
||||
the address of a mutable (non-constant) struct exception_context
|
||||
wherever those statements are used. Subject to that constraint, the
|
||||
application may declare a variable of this name anywhere it likes
|
||||
(inside a function, in a parameter list, or externally), and may
|
||||
use whatever storage class specifiers (static, extern, etc) or type
|
||||
qualifiers (const, volatile) it likes. Examples:
|
||||
|
||||
static struct exception_context
|
||||
* const the_exception_context = &foo;
|
||||
|
||||
{ struct exception_context *the_exception_context = bar; ... }
|
||||
|
||||
int blah(struct exception_context *the_exception_context, ...);
|
||||
|
||||
extern struct exception_context the_exception_context[1];
|
||||
|
||||
The last example illustrates a trick that avoids creating a pointer
|
||||
object separate from the structure object.
|
||||
|
||||
The name could even be a macro, for example:
|
||||
|
||||
struct exception_context ec_array[numthreads];
|
||||
#define the_exception_context (ec_array + thread_id)
|
||||
|
||||
Be aware that the_exception_context is used several times by the
|
||||
Try/Catch/Throw macros, so it shouldn't be expensive or have side
|
||||
effects. The expansion must be a drop-in replacement for an
|
||||
identifier, so it's safest to put parentheses around it.
|
||||
|
||||
|
||||
void init_exception_context(struct exception_context *ec);
|
||||
|
||||
For context structures allocated statically (by an external
|
||||
definition or using the "static" keyword), the implicit
|
||||
initialization to all zeros is sufficient, but contexts allocated
|
||||
by other means must be initialized using this macro before they
|
||||
are used by a Try/Catch statement. It does no harm to initialize
|
||||
a context more than once (by using this macro on a statically
|
||||
allocated context, or using this macro twice on the same context),
|
||||
but a context must not be re-initialized after it has been used by a
|
||||
Try/Catch statement.
|
||||
|
||||
|
||||
Try statement
|
||||
Catch (expression) statement
|
||||
|
||||
The Try/Catch/Throw macros are capitalized in order to avoid
|
||||
confusion with the C++ keywords, which have subtly different
|
||||
semantics.
|
||||
|
||||
A Try/Catch statement has a syntax similar to an if/else
|
||||
statement, except that the parenthesized expression goes after
|
||||
the second keyword rather than the first. As with if/else,
|
||||
there are two clauses, each of which may be a simple statement
|
||||
ending with a semicolon or a brace-enclosed compound statement.
|
||||
But whereas the else clause is optional, the Catch clause is
|
||||
required. The expression must be a modifiable lvalue (something
|
||||
capable of being assigned to) of the exact same type passed to
|
||||
define_exception_type().
|
||||
|
||||
If a Throw that uses the same exception context as the Try/Catch is
|
||||
executed within the Try clause (typically within a function called
|
||||
by the Try clause), and the exception is not caught by a nested
|
||||
Try/Catch statement, then a copy of the exception will be assigned
|
||||
to the expression, and control will jump to the Catch clause. If no
|
||||
such Throw is executed, then the assignment is not performed, and
|
||||
the Catch clause is not executed.
|
||||
|
||||
Regardless of whether an exception is caught, the expression is
|
||||
always evaluated exactly once, which is significant if it has side
|
||||
effects, for example:
|
||||
|
||||
Try foo();
|
||||
Catch (p[++i].e) { ... }
|
||||
|
||||
IMPORTANT: Jumping into or out of a Try clause (for example via
|
||||
return, break, continue, goto, longjmp) is forbidden--the compiler
|
||||
will not complain, but bad things will happen at run-time. Jumping
|
||||
into or out of a Catch clause is okay, and so is jumping around
|
||||
inside a Try clause. In many cases where one is tempted to return
|
||||
from a Try clause, it will suffice to use Throw, and then return
|
||||
from the Catch clause. Another option is to set a flag variable and
|
||||
use goto to jump to the end of the Try clause, then check the flag
|
||||
after the Try/Catch statement.
|
||||
|
||||
IMPORTANT: The values of any non-volatile automatic variables
|
||||
changed within the Try clause are undefined after an exception is
|
||||
caught. Therefore, variables modified inside the Try block whose
|
||||
values are needed later outside the Try block must either use static
|
||||
storage or be declared with the "volatile" type qualifier.
|
||||
|
||||
|
||||
Throw expression;
|
||||
|
||||
A Throw statement is very much like a return statement, except that
|
||||
the expression is required. Whereas return jumps back to the place
|
||||
where the current function was called, Throw jumps back to the Catch
|
||||
clause of the innermost enclosing Try clause. The expression must
|
||||
be compatible with the type passed to define_exception_type(). The
|
||||
exception must be caught, otherwise the program may crash.
|
||||
|
||||
Slight limitation: If the expression is a comma-expression it must
|
||||
be enclosed in parentheses.
|
||||
|
||||
|
||||
Try statement
|
||||
Catch_anonymous statement
|
||||
|
||||
When the value of the exception is not needed, a Try/Catch statement
|
||||
can use Catch_anonymous instead of Catch (expression).
|
||||
|
||||
|
||||
Everything below this point is for the benefit of the compiler. The
|
||||
application programmer should pretend not to know any of it, because it
|
||||
is subject to change.
