If compiling without backtrace or BFD support, we initialise the
location to store return addresses incorrectly, leaving a dangling
pointer which we then right over.
Most consumers never read this, so it seemed to work most of the time by
just overwriting a random bit of memory.
This probably has security implications, because throwing an exception
can clobber random bits of memory, though not with attacker-controlled
data.
Implement a method for getting attribytes of a file system path. Reuse
the implementation of -fileSystemAttributesAtPath: for this purpose but
export the last system errors to the caller. Make
-fileSystemAttributesAtPath: use the new implementation, without
exposing error info to the caller.
Currently, NSURLConnectionDelegate methods were defined as a category of
an NSObject. The same definitions were copied over to a new
NSURLConnectionDelegate protocol, introduced in OSX 10.7.
Declare the NSURLCredentialPersistenceSynchronizable enumeration case to
NSURLCredential persistence options. Since GNUstep does not support
iCloud synchronization for credentials, this case will default to
NSURLCredentialPersistencePermanent.
Improve handling of NSURL authentication methods. Make "HTMLForm"
authentication a no-op as it should be instead of making it fall back to
Basic authentication.
Add stubs for NTLM and Negotiate IIS methods. They should be easily
implementable given the current framework for authentication methods.
Add stubs for ClientCertificate and ServerTrust authentication methods.
A blocker for supporting them is the lack of a Security.framework
implementation (since they rely on SecTrustRef). They would also require
additions to the current SSL handling code for GNUstep https requests.
Also stub the -distinguishedNames property of NSURLProtectionSpace,
which also deals with certificate-related authentication methods.
Add new values for the NSURLCachePolicy enum. Although
NSURLRequestReloadIgnoringLocalAndRemoteCacheData and
NSURLRequestReloadRevalidatingCacheData have been left unimplemented,
the same applies for the reference platform, so not supporting it does
not break API compatibility.
Implement NSMakeCollectable(), an interface which makes CoreFoundation
objects eligible for garbage collection.
Since garbage collection is a totally deprecated API, its implementation
is a no-op, which may cause objects that rely on it to leak. However, it
doesn't look like supporting actual garbage collection at this point
will bring a gain to the project -- and having this function available
will avoid breaking builds that rely on it.
Make -[NSHTTPCookie isSessionOnly] and -[NSHTTPCookie isSecure] methods
become properties if possible, so that they can be also queried as
`cookie.sessionOnly` and `cookie.secure`. This increases compatibility
with applications that rely on this notation.
Create NSFileManagerDelegate, a more modern manner to verify whether to
proceed a file operation after an error or whether an operation should
actually be performed by NSFileManager.
No functionality using the delegate is yet implemented.
Create an unimplemented stub for NSURL's -getResourceValue:... method,
which can gather a numerous set of information about a URL.
Define the constants which are passed into -getResourceValue:... for
requiring information so that a build that relies on this method does
not break.
The OSX filesystem implements "aliases", a species of symlink which
tracks its source if it was moved. Create stubs for the NSURL functions
which handle these aliases.
Declare a system clock change notification. Base still does not emit
this notification, but this allows applications that wait for it not to
have their build broken.
Add the NSCalendarOptions enum to NSCalendar for compatibility purposes.
While NSCalendar does not yet know how to handle them, it will not
generate build errors in projects that attempt to use them.
Add new calendar identifier constants to NSCalendar, to add
compatibility for newer OSX applications. Some identifiers do not hold
parity with the older equivalents and have been left unimplemented, with
the gregorian calendar as a fallback.
Create the NSEdgeInsets struct in NSGeometry, introduced in OSX 10.7.
Add helper functions for creating these insets.
This struct is not used in Base. Rather, it is used as part of newer
APIs in GUI.
Create a no-file-exists error to the FoundationErrors enums. No function
is yet implemented to throw this error, but it has been added for
compatibility with applications that handle it.
To keep compatibility with compilers prior to Objective-C 2.0 support
(added in the GCC 4.6 series), we are unable to always declare @property
attributes in classes. However, compatibility with dot-syntax
applications require us to define properties if we can.
We already had some checks for the GS_HAS_DECLARED_PROPERTIES macro to
see whether we could or could not declare properties (or whether we
should fall back to manual getter/setter defining). However, it seems
this macro never got defined.
This commit adds this macro, checking whether we possess either GCC >=
4.6 or Clang.
