Description:
mysqldump with -X and -R does not dump routines! 

this is a serious problem - i could be under the impression I am backing up my routines whereas I am not.

How to repeat:
mysqldump -uroot -pmysql -P3351 -X --no-data --hex-blob --create-options  -R --databases sakila > sakila-xml.txt

look in the output file for rewards_report. It is not there.
Compare it to this dump:

mysqldump -uroot -pmysql -P3351 --no-data --hex-blob --create-options  -R --databases sakila > sakila-sql.txt

Suggested fix:
add support for stored routines. while you're at it, check if triggers and events don't suffer from the same problem.

Thank you for the report.

Verified as described. Triggers and events are also affected.

Thanks Sveta for verifying. I found a similar issue with VIEWs - you can use the same sakila command line to reproduce. For now I consider the issue related to this bug. Please let me know if this needs a separate bug report and I'll add it.

Foreign keys are also not dumped in XML output. Please let me know if I should create a separate issue for that.

Roland, thank you for the feedback.

I think separate bug for new limitations is good to have.

Btw I can not confirm bug with view:

<table_structure name="v1">
                <field Field="1" Type="int(1)" Null="NO" Key="" Default="0" Extra="" />
                <options Name="v1" Comment="VIEW" />
</table_structure>

Regarding foreign keys problem confirmed. There is only key information and no info this is foreign key in the output:

...
                <key Table="i2" Non_unique="1" Key_name="f2" Seq_in_index="1" Column_name="f2" Collation="A" Cardinality="0" Null="YES" Index_type="BTREE" Comment="" Index_comment="" />

For create table i2(f1 int not null primary key, f2 int, foreign key(f2) references i1(f1)) engine=innodb;

Hi sveta, 

in the example you quote regarding the views, where is the view code? surely I can't recreate the view based on only the list of columns?

Roland,

thank you for the correction. Problem with VIEWs exists as well.

Fixed in 5.1+. Documented in the 5.1.62, 5.5.21, and 5.6.5 changelogs as follows:

      When used with the --xml option, mysqldump --routines failed to dump any
      stored routines, triggers, or events.

Also noted issue and fix in 5.1/5.5/5.6 Manual's description of mysqldump options.

Closed.
