We'd been using crypto_digest_dup() and crypto_digest_assign() here,
but they aren't necessary. Instead we can just use the stack to
store the previous state of the SHA_CTX and avoid a malloc/free pair.
Closes ticket 24914.
For 23847, we want Tor to be able to shut down and then restart in
the same process. Here's a patch to make the Tor binary do that.
To test it, you need to build with --enable-restart-debugging, and
then you need to set the environment variable TOR_DEBUG_RESTART.
With this option, Tor will then run for 5 seconds, then restart
itself in-process without exiting. This only happens once.
You can change the 5-second interval using
TOR_DEBUG_RESTART_AFTER_SECONDS.
Implements ticket 24583.
* ADDS several `AC_MSG_RESULT`s which print the result of our checks
for our rust dependencies and a check for a suitable rustc compiler
version.
* FIXES#24612: https://bugs.torproject.org/24612
This patch adds support for Android's logging subsystem in Tor. When
debugging Android applications it is useful to be able to collect
information about the application running on the platform via the
various system services that is available on the platform.
This patch allows you to add "Log notice android" to your torrc and have
Tor send everything above and including the notice severity to Android's
ring buffer which can be inspected using the 'adb logcat' program.

Previously we would detect the system openssl on OSX, and then fail
to use it, since we required Open 1.0.1 or later. That's silly!
Instead of looking for RAND_add(), look for TLSv1_1_method(): it was
introduced in 1.0.1, and is also present in LibreSSL.
Also, add the hombebrew path to our search path here.
Fixes bug 23602; bugfix on 0.2.7.2-alpha.
Add a detection for the KIST scheduler in our build system and set

The GNU C Library (glibc) offers an function which allocates the
necessary memory automatically [0]. When it is available, we use that.
Otherwise we depend upon the `getcwd` function which requires a
preallocated buffer (and its size). This function was used incorrectly
by depending on the initial buffer size being big enough and otherwise
failing to return the current working directory. The proper way of
getting the current working directory requires a loop which doubles the
buffer size if `getcwd` requires it. This code was copied from [1] with
modifications to fit the context.

Many places in our code assume that uint8_t is the same type as
unsigned char. Test this assumption in the configure script. This is
important because of the privileged aliasing properties of character
types in C.
Fixes#22410.
This adds a couple of configure commands to control whether we're
requiring all dependencies to be available locally (default) or not
(--enable-cargo-online-mode). When building from a tarball, we require
the RUST_DEPENDENCIES variable to point to the local repository of
crates. This also adds src/ext/rust as a git submodule that contains
such a local repository for easy setup.
Passing --enable-cargo-online-mode during configure allows cargo to make
network requests while building Tor or running tests. If this flag is
not supplied, the dependencies need to be available in the form of a
local mirror.
Introduce a way to optionally enable Rust integration for our builds. No
actual Rust code is added yet and specifying the flag has no effect
other than failing the build if rustc and cargo are unavailable.
This commit adds the src/trace directory containing the basics for our tracing
subsystem. It is not used in the code base. The "src/trace/debug.h" file
contains an example on how we can map our tor trace events to log_debug().
The tracing subsystem can only be enabled by tracing framework at compile
time. This commit introduces the "--enable-tracing-debug" option that will
make all "tor_trace()" function be maped to "log_debug()".

This patch adds support for enabling support for Zstandard to our configure
script. By default, the --enable-zstd option is set to "auto" which means if
libzstd is available we'll build Tor with Zstandard support.

This patch adds support for enabling support for LZMA to our configure
script. By default, the --enable-lzma option is set to "auto" which
means if liblzma is available we'll build Tor with LZMA support.
