From inspecting the call sites of utoa, it appears that some of them
(especially the recent cleanup patch which added the strdup there) wanted
to prevent overwriting a local variable by repeated call (to utoa) using
the same variable as argument. This commit instead makes such call sites
strdup the variable itself before passing it to utoa. That seems cleaner
considering that it does not seem utoa's contract to do so (strdup its
parameter that is).
If there are two concurrent pg_repack commands are run on the same
table, the one starting later fails with error message:
Another pg_repack command may be running on the table. Please try again.
The document says this is shown as ERROR, but actualy is WARNING.
This patch includes one global counter (temp_obj_num) which counts number of temporary objects created by pg_repack. Correct order of deletion of temporary object as per count avoids unintentional error messages.
pgut version renamed to avoid confusion with the server version.
(I wonder why there is such a duplication of interfaces and
implementations there though...)
Previously, pg_repack shows "ERROR: ERROR: relation foo does not
exist" when specify non-existing table. Though the first ERROR
is from pg_repack and the second ERROR is from PostgreSQL server,
some users might think that pg_repack shows error level twice
wrongly.
"Waiting for %d transactions to finish. First PID: %s"
message. Display it on every loop through the SQL_XID_ALIVE check
(i.e. every second), instead of only when the number of transactions
we're waiting on changes -- previously, it was too easy for that
important message to get lost in other messages.
And don't display the message at all when running under pg_regress,
i.e. as part of `make installcheck`. We had been getting occasional
errors from pg_regress when autovacuum was running and that message
got logged.
These calls can require an access share lock on the table, which might
conflict with an existing or later acquires lock. So perform these calls
while we already have an exclusive lock on the table. This unfortuantely
means that we ave to remove the constness of the table parameter to
repack_one_table, as it is not modifying the table object to set up the
indexes.
problem was really about the OID being interpreted as an integer
literal upon input, and overflowing its integer space before even making
it into pg_try_advisory_lock(). (We do still need to add -2147483648 to
make the result fit into an integer, as 4b3347 does.)
Hopefully fixes issue #30, for real this time.
4-byte int accepted by the two-argument form of pg_try_advisory_lock()
we are using.
Fixes#30. Thanks to Mark Steben and Greg Sabino Mullane for the report
and diagnosis.
Prior to 506104686b these DELETEs had been done in large batches (of
DEFAULT_PEEK_COUNT size), but that naive method of choosing rows to
delete was unsafe. Here we continue to keep track of which rows must
be deleted as we process them.
Adds support for repacking only the tables in a specified schema. This
doesn't support --only-indexes mode, but that seems alright for now.
Fix merge conflicts, and make a few tweaks along the way:
* bump version to 1.3-dev0
* add Beena to list of maintainers
* documentation wordsmithing
* fix up the INFO message printed for each index in --index or
--only-indexes mode, so that it is only printed once per index, and
prints the name of the original index, not that of the transient
index_%u name.
