Description:
From time to time timestamps of generated sql_yacc.h and sql_yacc.cc
are older than their source -- sql_yacc.yy.

For instance:
daily-next-mr-bugfixing
Build from 2010-Aug-10.
Source archive: 2137295.mysql-5.6.99-m5.tar.gz
> ls -l --full-time sql/sql_yacc.*
-rw-r--r-- 1 alik alik 1703719 2010-08-10 18:37:22.000000000 +0400 sql/sql_yacc.cc
-rw-r--r-- 1 alik alik   31073 2010-08-10 18:37:22.000000000 +0400 sql/sql_yacc.h
-rw-r--r-- 1 alik alik  442963 2010-08-10 18:37:23.000000000 +0400 sql/sql_yacc.yy

That causes build failures if yacc/bison is not available on the box:
sql_yacc.yy is newer, thus sql_yacc.h/sql_yacc.cc should be re-generated,
but there is no tool for that.

How to repeat:
Check out PB.

Thank you for the report.

Verified as described.

triage: setting to SR55RC (assuming can lead to build failures) (w2 can address the issue by manually touching the file

Sveta and Alik,

Have you by any chance saved the log for the bootstrap and the tar source file for this build ?

Thanks,
Hery

We use cpack for unpacking the source, but due to a bug in cpack, the timestamp is not preserved. It will be fixed in the next release of cpack 2.8.3. In the meantime, a temporary fix has been checked into the pb2 scripts.

Thanks,
Hery
