see PR openssl#3203 Future versions of OpenSSL use the canonical terms "ECDHE" and "DHE" as configuration strings and compilation constants. This patch introduces aliases so that the stable 1.0.1 branch can be forward-compatible with code and configuration scripts that use the normalized terms, while avoiding changing any library output for stable users.

Usage:
ghlink [<option>...] [<file>...]
Concatenate the given file(s) to standard output, converting repository
locations into GitHub links. If no file is given, read from stdin.
Options:
--help
Print a brief help message and exit.
--man
Print the manual page and exit.
--markdown | -m
Convert the locations to links in markdown syntax, with the location
in square brackets, followed by the link in parentheses.
--permanent | -p
Always resolve branches to (unabbreviated) commit-ids for printing
the link.
--list | -l
List only the links of all locations found, and omit the rest of the
text. This option is useful together with the --permanent option to
create GitHub permalinks, see EXAMPLES section below.

During my testing (*), I got below stack about leaked memory. - at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage) - this calls into Azure, then into curl, and then into OpenSSL - curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper) - OpenSSL initializes the random number generator and stores it in some random number generator context object (--> *RAND_get0_public) - this object is registered via pthread_key_create and pthread_setspecific registered in TLS - if registerAzureObjectStorage was the only place which initializes the RNG, we could argue that the leaked memory does not matter anyways as it is released after shutdown - RAND_get0_public also registers a free handler (rand_delete_thread_state) that runs in TLS, so the memory is released also if registration is called from arbitrary other threads. In sum: this is a false positive.

During my testing (*), I got below stack about leaked memory. - at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage) - this calls into Azure, then into curl, and then into OpenSSL - curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper) - OpenSSL initializes the random number generator and stores it in some random number generator context object (--> *RAND_get0_public) - this object is registered via pthread_key_create and pthread_setspecific registered in TLS - if registerAzureObjectStorage was the only place which initializes the RNG, we could argue that the leaked memory does not matter anyways as it is released after shutdown - RAND_get0_public also registers a free handler (rand_delete_thread_state) that runs in TLS, so the memory is released also if registration is called from arbitrary other threads. In sum: this is a false positive.

During my testing (*), I got below stack about leaked memory. - at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage) - this calls into Azure, then into curl, and then into OpenSSL - curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper) - OpenSSL initializes the random number generator and stores it in some random number generator context object (--> *RAND_get0_public) - this object is registered via pthread_key_create and pthread_setspecific registered in TLS - if registerAzureObjectStorage was the only place which initializes the RNG, we could argue that the leaked memory does not matter anyways as it is released after shutdown - RAND_get0_public also registers a free handler (rand_delete_thread_state) that runs in TLS, so the memory is released also if registration is called from arbitrary other threads. In sum: this is a false positive.

During my testing (*), I got below stack about leaked memory. - at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage) - this calls into Azure, then into curl, and then into OpenSSL - curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper) - OpenSSL initializes the random number generator and stores it in some random number generator context object (--> *RAND_get0_public) - this object is registered via pthread_key_create and pthread_setspecific registered in TLS - if registerAzureObjectStorage was the only place which initializes the RNG, we could argue that the leaked memory does not matter anyways as it is released after shutdown - RAND_get0_public also registers a free handler (rand_delete_thread_state) that runs in TLS, so the memory is released also if registration is called from arbitrary other threads. In sum: this is a false positive.

During my testing (*), I got below stack about leaked memory. - at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage) - this calls into Azure, then into curl, and then into OpenSSL - curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper) - OpenSSL initializes the random number generator and stores it in some random number generator context object (--> *RAND_get0_public) - this object is registered via pthread_key_create and pthread_setspecific registered in TLS - if registerAzureObjectStorage was the only place which initializes the RNG, we could argue that the leaked memory does not matter anyways as it is released after shutdown - RAND_get0_public also registers a free handler (rand_delete_thread_state) that runs in TLS, so the memory is released also if registration is called from arbitrary other threads. In sum: this is a false positive.

During my testing (*), I got below stack about leaked memory. - at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage) - this calls into Azure, then into curl, and then into OpenSSL - curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper) - OpenSSL initializes the random number generator and stores it in some random number generator context object (--> *RAND_get0_public) - this object is registered via pthread_key_create and pthread_setspecific registered in TLS - if registerAzureObjectStorage was the only place which initializes the RNG, we could argue that the leaked memory does not matter anyways as it is released after shutdown - RAND_get0_public also registers a free handler (rand_delete_thread_state) that runs in TLS, so the memory is released also if registration is called from arbitrary other threads. In sum: this is a false positive.

Future versions of OpenSSL use the canonical terms "ECDHE" and "DHE"
as configuration strings and compilation constants. This patch
introduces aliases so that the stable 1.0.1 branch can be
forward-compatible with code and configuration scripts that use the
normalized terms, while avoiding changing any library output for
stable users.
