23 years agoattached is a patch that makes SysV semaphore emulation
Bruce Momjian [Wed, 17 Jan 2001 22:11:19 +0000 (22:11 +0000)]
attached is a patch that makes SysV semaphore emulation
using POSIX semaphores more robust on Darwin 1.2/Mac OS X
Public Beta.  this is for the version of 7.1 available
via anon cvs as of Jan 14 2001 14:00 PST.

since the semaphores and shared memory created by this
emulator are shared with the backends via fork(), their
persistent names are not necessary.  removing their
names with shm_unlink() and sem_unlink() after creation
obviates the need for any "ipcclean" function.  further,
without these changes, the shared memory (and, therefore,
the semaphores) will not be re-initialized/re-created after
the first execution of the postmaster, until reboot
or until some (non-existent) ipcclean function is executed.

this patch does the following:

   1) if the shared memory segment "SysV_Sem_Info" already
      existed, it is cleaned up.  it shouldn't be there anyways.

   2) the real indicator for whether the shared memory/semaphore
      emulator has been initialized is if "SemInfo" has been
      initialized.  the shared memory and semaphores must be
      initialized regardless of whether there was a garbage shared
      memory segment lying around.

   3) the shared memory segment "SysV_Sem_Info" is created with "O_EXCL"
      to catch the case where two postmasters might be starting
      simultaneously, so they don't both end up with the same shared
      memory (one will fail).  note that this can't be done with the
      semaphores because Darwin 1.2 has a bug where attempting to
      open an existing semaphore with "O_EXCL" set will ruin the
      semaphore until the next reboot.

   4) the shared memory segment "SysV_Sem_Info" is unlinked after
      it is created.  it will then exist without a name until the
      postmaster and all backend children exit.
   5) all semaphores are unlinked after they are created.  they'll
      then exist without names until the postmaster and all backend
      children exit.

Attached is a set of patches for a couple of bugs dealing with
timestamps in JDBC.

Bug#1) Incorrect timestamp stored in DB if client timezone different
than DB.

The buggy implementation of setTimestamp() in PreparedStatement simply
used the toString() method of the java.sql.Timestamp object to convert
to a string to send to the database.  The format of this is yyyy-MM-dd
hh:mm:ss.SSS which doesn't include any timezone information.  Therefore
the DB assumes its timezone since none is specified.  That is OK if the
timezone of the client and server are the same, however if they are
different the wrong timestamp is received by the server.  For example if
the client is running in timezone GMT and wants to send the timestamp
for noon to a server running in PST (GMT-8 hours), then the server will
receive 2000-01-12 12:00:00.0 and interprete it as 2000-01-12
12:00:00-08 which is 2000-01-12 04:00:00 in GMT.  The fix is to send a
format to the server that includes the timezone offset.  For simplicity
sake the fix uses a SimpleDateFormat object with its timezone set to GMT
so that '+00' can be used as the timezone for postgresql.  This is done
as SimpleDateFormat doesn't support formating timezones in the way
postgresql expects.

Bug#2) Incorrect handling of partial seconds in getting timestamps from
the DB

When the SimpleDateFormat object parses a string with a format like
yyyy-MM-dd hh:mm:ss.SS it expects the fractional seconds to be three
decimal places (time precision in java is miliseconds = three decimal
places).  This seems like a bug in java to me, but it is unlikely to be
fixed anytime soon, so the postgresql code needed modification to
support the java behaviour.  So for example a string of '2000-01-12
12:00:00.12-08' coming from the database was being converted to a
timestamp object with a value of 2000-01-12 12:00:00.012GMT-08:00.  The
fix was to check for a '.' in the string and if one is found append on
an extra zero to the fractional seconds part.

Bug#3) Performance problems

In fixing the above two bugs, I noticed some things that could be
improved.  In PreparedStatement.setTimestamp(),
PreparedStatement.setDate(), ResultSet.getTimestamp(), and
ResultSet.getDate() these methods were creating a new SimpleDateFormat
object everytime they were called.  To avoid this unnecessary object
creation overhead, I changed the code to use static variables for
keeping a single instance of the needed formating objects.
Also the code used the + operator for string concatenation.  As everyone
should know this is very inefficient and the use of StringBuffers is
prefered.

I also did some cleanup in ResultSet.getTimestamp().  This method has
had multiple patches applied some of which resulted in code that was no
longer needed.  For example the ISO timestamp format that postgresql
uses specifies the timezone as an offset like '-08'.  Code was added at
one point to convert the postgresql format to the java one which is
GMT-08:00, however the old code was left around which did nothing.  So
there was code that looked for yyyy-MM-dd hh:mm:sszzzzzzzzz and
yyyy-MM-dd hh:mm:sszzz.  This second format would never be encountered
because zzz (i.e. -08) would be converted into the former (also note
that the SimpleDateFormat object treats zzzzzzzzz and zzz the same, the
number of z's does not matter).

There was another problem/fix mentioned on the email lists today by
mcannon@internet.com which is also fixed by this patch:

Bug#4) Fractional seconds lost when getting timestamp from the DB
A patch by Jan Thomea handled the case of yyyy-MM-dd hh:mm:sszzzzzzzzz
but not the fractional seconds version yyyy-MM-dd hh:mm:ss.SSzzzzzzzzz.

The code is fixed to handle this case as well.

+18 -18
Eliminate some of the more blatant platform-dependencies ... it

Which basically changes u_int*_t -> uint*_t, so now it does not
compile neither under Debian 2.2 nor under NetBSD 1.5 which
is platform independent<B8> all right.  Also it replaces $KAME$
with $Id$ which is Bad Thing. PostgreSQL Id should be added as a
separate line so the file history could be seen.

So here is patch:

* changes uint*_t -> uint*.  I guess that was the original
  intention
* adds uint64 type to include/c.h because its needed
  [somebody should check if I did it right]
* adds back KAME Id, because KAME is the master repository
* removes stupid c++ comments in pgcrypto.c
* removes <sys/types.h> from the code, its not needed
