Change subject: IMPALA-11275: write thread info to log during minidump ...................................................................... Patch Set 1: (2 comments) Couple initial comments http://gerrit.cloudera.org:8080/#/c/18508/1/be/src/util/minidump.cc File be/src/util/minidump.cc: http://gerrit.cloudera.org:8080/#/c/18508/1/be/src/util/minidump.cc@69 PS1, Line 69: static void my_i64tohex(int64_t w, char out[]) { : static const char* digits = "0123456789abcdef"; : for (size_t i = 0, j=64; i < 16; ++i, j -= 4) { : out[i] = digits[(w>>j) & 0x0f]; : } : } For this function, it would be useful to be able to unit test the conversion to hex and/or confirm that we'll get the same result as PrintId in debug-util.h. As a specific point, at i=0, j should be 60 and at i=15, j should be 0. One option would be for debug-util.h to add an equivalent of PrintId() tuned for the compromised context. i.e. // 16 + 16 + 1 separator #define TUNIQUE_ID_BUFFER_SIZE 33 PrintIdCompromised(const TUniqueId& id, char out[]); (or whatever would be better names for these) That would allow for a unit test in util/debug-util-test.cc that compares the representation from PrintId() to PrintIdCompromised(). http://gerrit.cloudera.org:8080/#/c/18508/1/be/src/util/minidump.cc@79 PS1, Line 79: auto Minor style point: We generally follow the Google C++ style guide, and we avoid using auto for most variable definitions. https://google.github.io/styleguide/cppguide.html#Type_deduction We commonly use auto for iterators, because the type definitions are pretty tedious and can be error prone. -- To view, visit http://gerrit.cloudera.org:8080/18508 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Iea2bdf10db29a0f8ccbe5e767b708781d42a9b8a Gerrit-Change-Number: 18508 Gerrit-PatchSet: 1 Gerrit-Owner: Michael Smith <michael.sm...@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Joe McDonnell <joemcdonn...@cloudera.com> Gerrit-Reviewer: Michael Smith <michael.sm...@cloudera.com> Gerrit-Comment-Date: Wed, 11 May 2022 15:54:16 +0000 Gerrit-HasComments: Yes
