Conflicts:
mbedtls.doxyfile - PROJECT_NAME - mbed TLS v2.16.6 chosen.
doc_mainpage.h - mbed TLS v2.16.6 version chosen.
hmac_drbg.h - line 260, extended description chosen.
- line 313, extended description chosen.
- line 338, extended description chosen.
version.h - 2.16.6 chosen.
CMakeLists.txt - 2.16.6 chosen.
test_suite_version.data - 2.16.6 chosen.
Makefile - 141 - manual correction - baremetal version of C_SOURCE_FILES
with variables for directories plus 2.16.6 CTAGS addition.
pkparse.c - lines 846 onwards - the asn1_get_nonzero_mpi implementation chosen.
ssl_tls.c - line 5269 - edited manually, left the ret=0, because baremetal has
a different behaviour since commit 87b5626, but added a debug
message that's new in 2.16.6.
all.sh:
- component_build_deprecated - chosen the refactored version from 2.16.6,
but with extra flags from baremetal.
- rest of the _no_xxx tests - merged make options to have PTHREAD=1 and
other changes from 2.16.6 (like -O1 instead of -O0).
- component_build_arm_none_eabi_gcc_no_64bit_multiplication - added
TINYCRYPT_BUILD=0 to the 2.16.6 version of make.
x509/req_app.c - left baremetal log but with mbedtls_exit( 0 ) call.
x509/crl_app.c - left baremetal log but with mbedtls_exit( 0 ) call.
x509/cert_app.c - left baremetal log but with mbedtls_exit( 0 ) call.
ssl/ssl_mail_client.c - left baremetal log but with mbedtls_exit( 0 ) call.
ssl/ssl_pthread_server.c - left baremetal log but with mbedtls_exit( 0 ) call.
ssl/ssl_fork_server.c - left baremetal log but with mbedtls_exit( 0 ) call.
ssl_client1.c - line 54 - left baremetal log but with mbedtls_exit( 0 ) call.
ssl_client2.c - line 54 - left baremetal log but with mbedtls_exit( 0 ) call.
- line 132 - new options of both branches added.
- skip close notify handled as in 2.16.6, but with `ssl` instead of `&ssl`.
- Merged the 2.16.6 usage split with additional baremetal usages.
- Merged options from baremetal and 2.16.6.
ssl_server.c - left baremetal log but with mbedtls_exit( 0 ) call.
ssl_server2.c - Merged the 2.16.6 usage split with additional baremetal usages.
config.pl - fixed missing defines from the documentation, removed duplicates,
and reorganised so that the documentation and excluded list
are ordered in the same way.
test_suite_x509parse.data - only added the two new pathlen tests.
x509_crt.c - change the return code by removing
MBEDTLS_ERR_X509_INVALID_EXTENSIONS, since it's added by
x509_crt_frame_parse_ext not by an "or", but by "+=".
Changelog - Assigned all entries to appropriate sections.
ssl-opt.sh - line 8263 - merged options.
- removed lines 1165 - 1176 - there was a duplicate test, probably
an artifact of previous merges.
check-files.py - sticked to old formatting.

Purpose
|
|
|
|
This script is a small wrapper around the abi-compliance-checker and
|
|
abi-dumper tools, applying them to compare the ABI and API of the library
|
|
files from two different Git revisions within an Mbed TLS repository.
|
|
The results of the comparison are either formatted as HTML and stored at
|
|
a configurable location, or are given as a brief list of problems.
|
|
Returns 0 on success, 1 on ABI/API non-compliance, and 2 if there is an error
|
|
while running the script. Note: must be run from Mbed TLS root.
