OSX/libsecurity_asn1/CHANGES.Apple

   1 Per the terms of the Mozilla Public License, version 1.1, this file contains
   2 a summary of the changes made by Apple Computer ("Apple") to source code
   3 originally developed by Netscape.

   5 General Notes
   6 -------------
   7
   8 1. This module, SecurityNssAsn1, is based on the Netscape Security
   9    Services ("NSS") portion of the Mozilla Browser project. The
  10    source upon which SecurityNssAsn1 was based was pulled from
  11    the Mozilla CVS repository, top of tree as of January 21, 2003.
  12    The SecurityNssAsn1 project contains only those portions of NSS
  13    used to perform BER encoding and decoding, along with minimal
  14    support required by the encode/decode routines.
  15
  16 2. The directory structure of SecurityNssAsn1 differs significantly
  17    from that of NSS, rendering simple diffs to document changes
  18    unwieldy. Diffs could still be performed on a file-by-file basis.
  19
  20 3. All Apple changes are flagged by the symbol __APPLE__, either
  21    via "#ifdef __APPLE__" or in a comment.

  24 Changes
  25 -------
  26
  27 1. Basic platform-specific support is in nsprPub/Source/nsprPortX.c.
  28    This support is specific to Mac OS X.
  29
  30 2. The fundamental data wrapper, SECItem, has been typedef'd to a
  31    CSSM_DATA. This provides interoperability between the code in
  32    this module with the code in the Apple Security framework.
  33
  34 3. Indication of signed integer types has moved from the
  35    source/destination of encoding/decoding (SecItem.type) to a flag
  36    in the template defining encoding/decoding rules
  37    (SEC_ASN1_SIGNED_INT in SEC_ASN1Template.kind). The default
  38    for ASN1 integer types, when this flag is not set, is unsigned.
  39
  40 4. The dynamic template resolution mechanism has been updated to
  41    provide the template chooser routine specific access to the
  42    SECItem being encoded to or decoded from. This faciliates
  43    efficient inline processing of many ASN_ANY and CHOICE types.
  44
  45 5. The source of the core secasn1e.c and secasn1d.c files has been
  46    reformatted to be legible with 4-space tabs. Contrary to the
  47    comments at the top of these files, these files were actually
  48    formatted for 8-space tabs.
  49
  50 6. Templates for encoding/decoding of fundamental ASN types was moved
  51    from secasn1d.c to a new file, asn1Templates.c. All other
  52    templates in the SecurityNssAsn1 source were written by Apple.
  53
  54 7. Updated the prcpucfg.h file to nspr-4.8.9 version.
  55
  56 8. Changed various integer types for variables and functions arguments
  57    to be 64 bits safe.
