For simplicity, the parsing of `adb devices -l` output is performed in a
single pass on the whole output.
This output was limited to 4096 bytes. Since there are about 100 chars
per device line, this limited the number of connected devices to ~40.
Increase to 65536 bytes to avoid a limitation in practice.
PR #3035 <https://github.com/Genymobile/scrcpy/pull/3035>
All adb commands are executed with an "interruptor", so that they can be
interrupted on Ctrl+C.
Make this interruptor optional, so that we could call "adb kill-server"
in OTG mode. This command always returns almost immediately anyway.
Ideally, we should make all blocking calls interruptible (including
libusb calls, by using the asynchronous API), but it's a lot of work,
and in practice it works well enough.
PR #3011 <https://github.com/Genymobile/scrcpy/pull/3011>
If several devices are connected (as listed by `adb devices`), it was
necessary to provide the explicit serial via -s/--serial.
If only one device is connected via USB (respectively, via TCP/IP), it
might be convenient to select it automatically. For this purpose, two
new options are introduced:
- -d/--select-usb: select the single device connected over USB
- -e/--select-tcpip: select the single device connected over TCP/IP
PR #3005 <https://github.com/Genymobile/scrcpy/pull/3005>
Currently, a device is selected either from a specific serial, or if it
is the only one connected.
In order to support selecting the only device connected via USB or via
TCP/IP separately, introduce a new selection structure.
PR #3005 <https://github.com/Genymobile/scrcpy/pull/3005>
This does nothing if the adb daemon is already started, but allows to
print any output/errors to the console.
Otherwise, the daemon starting would occur during `adb devices`, which
does not output to the console because the result is parsed.
PR #3005 <https://github.com/Genymobile/scrcpy/pull/3005>
Since the previous commit, if a serial is given via -s/--serial (either
a real USB serial or an IP:port), a device is selected if its serial
matches exactly.
In addition, if the user pass an IP without a port, then select any
device with this IP, regardless of the port (so that "192.168.1.1"
matches any "192.168.1.1:port"). This is also the default behavior of
adb.

The function assumed that the raw output of "adb connect" was a
NUL-terminated string, but it is not the case.
It this output did not end with a space or a new line character, then
sc_str_truncate() would write '\0' over the last character. Even worse,
if the output was empty, then sc_str_truncate() would write
out-of-bounds.
Avoid the error-prone sc_str_truncate() util function.

The parser assumed that its input was a NUL-terminated string, but it
was not the case: it is just the raw output of "adb devices ip route".
In practice, it was harmless, since the output always ended with '\n'
(which was replaced by '\0' on truncation), but it was incorrect
nonetheless.
Always write a '\0' at the end of the buffer, and explicitly parse as a
NUL-terminated string. For that purpose, avoid the error-prone
sc_str_truncate() util function.
Now that providing a serial is mandatory for adb commands where it is
relevant, the whole argv array may be built statically, without
allocations at runtime.
If no serial is passed, then the command would work if there is exactly
one device connected, but will fail with multiple devices.
To avoid such cases, ensure that a serial is always provided.
On Windows, adb is provided in the release archive. Most missing adb
issues come from users setting the ADB environment variable to an
incorrect value (on all platforms).
Suggesting to install platform-tools to solve the problem will just make
things worse (there will be one more adb in yet another location).
