We're now able to send packets faster than the device can handle them,
meaning that sometimes we're several packets through before the device
says "hey, wait, I can't write" and closes the connection. At best this
led to us reporting that we couldn't sync because "Connection reset";
at worst we'd get SIGPIPE because we were still streaming to a connection
that had already been closed.
This change renames adb_main adb_server_main, and moves the ignoring of
SIGPIPE into adb_commandline so it applies to both client and server (but
not adbd).
This change doesn't address the "wrong error message" part of the problem,
but at least it means you'll get *an* error message.

I put the conditional in the wrong place, not realizing that even the

adb_dirname might trample over the errno value we want to print. Move
the adb_dirname call out to a local to prevent this.

Unfortunately, this isn't backwards-compatible with the current shell
protocol because we made unknown shell: arguments errors. We could try
to commit the change to make them just warnings first, but how would
we know when everyone was running adbd with that change? Bumping the
protocol version doesn't help because that only affects the code running
on the host. And although we could add another feature to the reported
features, since shell_v2 is still in development, that doesn't seem
worthwhile.

Pulling symlinks was broken for directories, and it doesn't seem like
there's a good way to make it not broken, given that the protocol doesn't
have readlink (and we don't want to create symlinks on Windows, anyway).
The behavior for files doesn't seem to be especially useful, either.

Cleanup TODO and instead of (poorly) converting the device name from
wchar_t to char, just retrieve and store it as wchar_t, simplifying the
code.
This probably isn't necessary since device names are probably always
ASCII, but this cleans things up.

Now that we have a more standardized API (also available in Chromium),
switch to it. Another benefit is real error handling instead of just
killing the process on invalid Unicode.
Make UTF8ToWide()/WideToUTF8() set errno to EILSEQ on bad input. This is
the same error code that wcsrtombs(3) uses.
Update the unittest to check for EILSEQ.

On exit, these destructors get invoked while other threads might
still be using them, potentially causing a crash, and definitely
causing tsan to report a race condition.

With the dependency on libcutils (for gettid for non-bionic) removed,
this no longer breaks the build.

28416d6d33 broke adb shell on Windows
because it was calling unix_read() with a buffer size of 1 byte which
wasn't supported by unix_read()/_console_read().
This change makes _console_read() support such a small buffer by
maintaining an internal input buffer.
This lets us simplify the existing code that was already maintaining a
cached INPUT_RECORD.
Also eliminate some duplicate code in the big switch statement.

ae5a6c06cd made adb push use
android::base::ReadFileToString() for small files, but that API did not
support UTF-8 filenames on Windows, until this fix which does the
following:
- Add android::base::{WideToUTF8,UTF8ToWide}() which are only available
on Windows. The signatures are based on Chromium's APIs of the same
name.
- Add the namespace android::base::utf8 which has versions of APIs that
take UTF-8 strings. To use this, make sure your code is in a namespace
and then do "using namespace android::base::utf8;". On Windows, this will
make calls to open() call android::base::utf8::open(), and on other
platforms, it will just call the regular ::open().
- Make ReadFileToString() and WriteStringToFile() use utf8::open() and
utf8::unlink().
- Adapt unittests from Chromium.
- fastboot needs to link with libcutils because it links with libbase
which depends on libcutils for gettid() for logging.

Start of input is, by definition, the start of a line. Give the states
names to make the error clearer. We should also swallow the escape
character until/unless it's proven not to have been part of an escape
sequence. Finally, implement an ssh(1)-like -e option so the user can
choose -- or, more importantly, disable -- escape character handling.

I've been using these changes to compile with Visual Studio.
- GetFileBasename(): __FILE__ uses \ with Visual Studio.
- adb_trace.cpp: Apparently VS needs an ampersand before the function name.
- "expr1 ? : expr2" is a GCC extension.
- <algorithm> contains std::min().
- seekdir can't always be #define'd because some headers have members
named seekdir.
- adb_utils.cpp: Not really a compiler issue, just a random fix:
0x7F/DEL is not printable.

Add the following mount options to the /proc filesystem:
hidepid=2,gid=3009
This change blocks /proc access unless you're in group 3009
(aka AID_READPROC).
Please see
https://github.com/torvalds/linux/blob/master/Documentation/filesystems/proc.txt
for documentation on the hidepid option.
hidepid=2 is preferred over hidepid=1 since it leaks less information
and doesn't generate SELinux ptrace denials when trying to access
/proc without being in the proper group.
Add AID_READPROC to processes which need to access /proc entries for
other UIDs.

use the cmd command. Additionally, the APK will be streamed directly to
