Hello Kudu Jenkins,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#23).
Change subject: Add Google Breakpad support to Kudu
......................................................................
Add Google Breakpad support to Kudu
Breakpad creates minidumps upon crash, which are small files that
include stack-based information for each thread. These do not include
heap information, so they complement, not replace, core files for
debugging purposes.
This patch enables Google Breakpad for the kudu-tserver and kudu-master
processes.
Breakpad is part of the crash-reporting infrastructure open-sourced by
Google. It is also used by Mozilla Firefox and Google Chrome.
When a process crashes, Breakpad writes a small dump file called a
minidump to disk. Since these files are typically only a few MB in size,
this allows users to share critical crash information with developers
for offline analysis.
For more information, see the breakpad getting started docs at
http://chromium.googlesource.com/breakpad/breakpad/+/master/docs/getting_started_with_breakpad.md
By default, on crash, minidump files are written to a subdirectory of
the log directory for a given Kudu daemon process. This was chosen for
the following reasons:
1. The minidump files are relatively small, potentially comparable in
size to log files, and the log directory is a place an administrator
would look in when debugging.
2. This convention is consistent with what Apache Impala (incubating)
does for its minidump files.
Changes in this patch:
* Add breakpad to thirdparty.
* Add breakpad source archive creation script (Breakpad does not do
releases).
* Add a "hack" to the breakpad thirdparty installation routine to
forcibly add a breakpad/ prefix to the breakpad header files. This
frees us from having to modify our include path when building.
* Pull in (heavily modified) util/minidump.{cc,h} from Apache Impala
(incubating). The modifications consist of removing use of
boost::filesystem, conformance to the Kudu code style guidelines, and
some significant refactoring.
* Enable breakpad support for the kudu-tserver and kudu-master
processes.
* By default, invoke previously-installed signal handler if installed.
* Handle SIGUSR1 by safely using sigwait() to create minidumps on demand.
* Add #ifdefs and CMake logic for Linux.
* Add test for all the deadly signals to ensure we get both a stack
trace and a minidump, except for the case of SIGTERM, where we should
not get a minidump (by design).
* Change a few library unit tests that relied on SIGUSR1 to use another
signal for their testing, such as SIGHUP or SIGUSR2.
