* Fix a couple of bugs in win32 shmem name generation:Magnus Hagander2008-07-04
| | | | | * Don't cut off the prefix. With this fix, it's again readable. * Properly store it in the Global namespace as intended.
* Add $PostgreSQL$ markers to a lot of files that were missing them.Andrew Dunstan2008-05-17
| | | | | | | | | | This particular batch was just for *.c and *.h file. The changes were made with the following 2 commands: find . \( \( -name 'libstemmer' -o -name 'expected' -o -name 'ppport.h' \) -prune \) -o \( -name '*.[ch]' \) \( -exec grep -q '\$PostgreSQL' {} \; -o -print \) | while read file ; do head -n 1 < $file | grep -q '^/\*' && echo $file; done | xargs -l sed -i -e '1s/^\// /' -e '1i/*\n * $PostgreSQL:$ \n *' find . \( \( -name 'libstemmer' -o -name 'expected' -o -name 'ppport.h' \) -prune \) -o \( -name '*.[ch]' \) \( -exec grep -q '\$PostgreSQL' {} \; -o -print \) | xargs -l sed -i -e '1i/*\n * $PostgreSQL:$ \n */'
* Repair two places where SIGTERM exit could leave shared memory stateTom Lane2008-04-16
| | | | | | | | | | | | | | corrupted. (Neither is very important if SIGTERM is used to shut down the whole database cluster together, but there's a problem if someone tries to SIGTERM individual backends.) To do this, introduce new infrastructure macros PG_ENSURE_ERROR_CLEANUP/PG_END_ENSURE_ERROR_CLEANUP that take care of transiently pushing an on_shmem_exit cleanup hook. Also use this method for createdb cleanup --- that wasn't a shared-memory-corruption problem, but SIGTERM abort of createdb could leave orphaned files lying around. Backpatch as far as 8.2. The shmem corruption cases don't exist in 8.1, and the createdb usage doesn't seem important enough to risk backpatching further.
* Fix MinGW warnings re formats and unused variables. per ITAGAKI TakahiroAndrew Dunstan2008-04-16

* Add a new ereport auxiliary function errdetail_log(), which works the same asTom Lane2008-03-24
| | | | | | | | errdetail except the string goes only to the server log, replacing the normal errdetail there. This provides a reasonably clean way of dealing with error details that are too security-sensitive or too bulky to send to the client. This commit just adds the infrastructure --- actual uses to follow.

* Change StatementCancelHandler() to check the DoingCommandRead flag to decideTom Lane2008-01-26
| | | | | | | | | | | | | | | | | | whether to execute an immediate interrupt, rather than testing whether LockWaitCancel() cancelled a lock wait. The old way misclassified the case where we were blocked in ProcWaitForSignal(), and arguably would misclassify any other future additions of new ImmediateInterruptOK states too. This allows reverting the old kluge that gave LockWaitCancel() a return value, since no callers care anymore. Improve comments in the various implementations of PGSemaphoreLock() to explain that on some platforms, the assumption that semop() exits after a signal is wrong, and so we must ensure that the signal handler itself throws elog if we want cancel or die interrupts to be effective. Per testing related to bug #3883, though this patch doesn't solve those problems fully. Perhaps this change should be back-patched, but since pre-8.3 branches aren't really relying on autovacuum to respond to SIGINT, it doesn't seem critical for them.

* Use snprintf instead of wsprintf, and use getenv("APPDATA") instead ofMagnus Hagander2007-10-23
| | | | | | | | | | | | | | SHGetFolderPath. This removes the direct dependency on shell32.dll and user32.dll, which eats a lot of "desktop heap" for each backend that's started. The desktop heap is a very limited resource, causing backends to no longer start once it's been exhausted. We still have indirect depdendencies on user32.dll through third party libraries, but those can't easily be removed. Dave Page
* Fix failure to restart Postgres when Linux kernel returns EIDRM for shmctl().Tom Lane2007-07-02
| | | | | | | | | | | | | This is a Linux kernel bug that apparently exists in every extant kernel version: sometimes shmctl() will fail with EIDRM when EINVAL is correct. We were assuming that EIDRM indicates a possible conflict with pre-existing backends, and refusing to start the postmaster when this happens. Fortunately, there does not seem to be any case where Linux can legitimately return EIDRM (it doesn't track shmem segments in a way that would allow that), so we can get away with just assuming that EIDRM means EINVAL on this platform. Per reports from Michael Fuhr and Jon Lapham --- it's a bit surprising we have not seen more reports, actually.
* On win32, retry reading when WSARecv returns WSAEWOULDBLOCK. There seemMagnus Hagander2007-06-04

* Wording cleanup for error messages. Also change can't -> cannot.Bruce Momjian2007-02-01
| | | | | | | | | | | | | | Standard English uses "may", "can", and "might" in different ways: may - permission, "You may borrow my rake." can - ability, "I can lift that log." might - possibility, "It might rain today." Unfortunately, in conversational English, their use is often mixed, as in, "You may use this variable to do X", when in fact, "can" is a better choice. Similarly, "It may crash" is better stated, "It might crash".
* On Windows, use pgwin32_waitforsinglesocket() instead of select() to wait forTom Lane2007-01-26
| | | | | | | | | | input in the stats collector. Our select() emulation is apparently buggy for UDP sockets :-(. This should resolve problems with stats collection (and hence autovacuum) failing under more than minimal load. Diagnosis and patch by Magnus Hagander. Patch probably needs to be back-ported to 8.1 and 8.0, but first let's see if it makes the buildfarm happy...

However, I should try the solution now. It is necessary to clear the problem. Multi character-code exists together in message and log. It doesn't consider the data base encoding that the user intended....

* Fix infinite sleep and failes of send in Win32.Teodor Sigaev2006-10-13
| | | | | | | | | | | | | | | 1) pgwin32_waitforsinglesocket(): WaitForMultipleObjectsEx now called with finite timeout (100ms) in case of FP_WRITE and UDP socket. If timeout occurs then pgwin32_waitforsinglesocket() tries to write empty packet goes to WaitForMultipleObjectsEx again. 2) pgwin32_send(): add loop around WSASend and pgwin32_waitforsinglesocket(). The reason is: for overlapped socket, 'ok' result from pgwin32_waitforsinglesocket() isn't guarantee that socket is still free, it can become busy again and following WSASend call will fail with WSAEWOULDBLOCK error. See http://archives.postgresql.org/pgsql-hackers/2006-10/msg00561.php

* Fix statement_timeout on Win32 so that it properly treats micro-secondsBruce Momjian2006-08-09
| | | | | | | | as micro-seconds, rather than as 100 microseconds, as it does now. This actually fixes all setitimer calls on Win32, but statement_timeout is the most visible fix. Backpatch to 8.1.X. 8.0 works as documented.
