- Patch 95bb3cb886cb64be3ee5ace660b used `my_which` function in `10.2`
- Based on patch `355ee6877bec` from 10.3+ `command -v` is used instead of
`my_which` so we are changing in this patch also
- `ldconfig` is usually found in `/sbin` so make sure it is added in
`$PATH` variable
- This commit is based on patch 84fe9720a4d2483ff67b6a and suggestion of
Jean Weisbuch to use `ldconfig -p`
- Format of ldconfig output:
"libjemalloc.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libjemalloc.so.1"

Adding any unknown option to the "[mysqld_safe]" section makes
mysqld impossible to start with mysqld_multi. For example, after
adding the unknown option "numa_interleave" to the "[mysqld_safe]"
section, mysqld_multi exits with the following diagnostics:
[ERROR] /usr/local/mysql/bin/mysqld: unknown option '--numa_interleave'
To get rid of this behavior, this patch by default adds the "--loose-"
prefix to all unknown (for mysqld_safe) options. This behavior can be
enabled explicitly with the --ignore-unknown option and disabled with
the --no-ignore-unknown option.
Also add a check for tmp file being empty and bail out with a clear
error message in such a case, as mysqld_safe prevents normal stderr
from being displayed anywhere and would fail silently on this.
mysqld_safe --dry-run needs to either call exit or return, depending if
it is being sourced or not, otherise return can lead to the error:
return: can only `return' from a function or sourced script
The original fix suggestion was proposed by FaramosCZ <mschorm@centrum.cz>
Revert part of 64094e1 because mysqld_safe isn't just used for
Debian. As such references to specific packaging files like
/etc/mysql/debian.cnf shouldn't have passed a review.
There's also no history of why 64094e1 was needed based on
the history of debian/patches/38_scripts__mysqld_safe.sh__signals.dpatch
Other distos have survived without mysqld_safe handling signals.
c902d5a4ded2a492eb47379910111717dbded2d3 changed this to bash.
This isn't approprate as mysqld_safe is used by FreeBSD where
there is no bash by default.
The original reason to use bash seems related to MDEV-3279 which
was a dash bug fixed in 2009 - https://git.kernel.org/pub/scm/utils/dash/dash.git/commit/?id=3800d4934391b144fd261a7957aea72ced7d47ea
Working around 9 year old fixed bugs shouldn't be done here.
We have carried along this patch as a patch inside our sources
since 2012 (commit cfd4fcb0bc3d).
The validity of this has thus been vetted in production for years
and the review done now did not find otherwise.
A race in dash causes mysqld_safe to occasionally loop infinitely.
Fix by using bash instead.

As this is the last patch, we can also clean away usage of dpatch.

This same patch has been used also in MySQL packaging at Oracle
and in downstream Debian.org packages for both MySQL and MariaDB.

- Expand paths also for jemalloc
- Test also if tcmalloc or jemalloc is in /usr/lib64
- Take into account that .so has a version
- Remove automatic adding of flavors ( _minial, _debug). Better to
have user specify these directly
- Changed documentation link to MariaDB
- Don't give extra error if mysqld_safe_helper doesn't exist
This is regression caused by patch of mdev-10767.
1st problem :- mktmp is invoked without '-t' or specifing tmp directory.
2nd problem :- Since eval_log_error redirect stderr to stdout '2>' will
return nothing. and hence $wr_logfile will be empty.
Patch Credit:- Andrii Nikitin
Problem:- To create file in /tmp dir mysqld require permission initrc_tmp_t.
And mysqld does not have his permission.
Solution:- Instead of giving mysqld permission of initrc_tmp_t , we redirected
log to file in /tmp dir through shell. I also removed a earlier workarround
in mysqld_safe.sh , which create tmp log file in datadir.
Fix of Bug#25088048 caused paths to be relative, not absolute, this
proved to be problematic.
Fix is to still ignore current working directory, however switch to
using full path of basedir, which is set to parent directory of bin/
directory where mysqld_safe is located.
References to legacy tool mysql_print_defaults are removed, only
my_print_defaults is used these days.
This will also fix:
