Bruce Momjian	f9bb944cd8	pg_test_fsync: add C comment about direct I/O and write size failure Report from Marti Raudsepp	12 years ago
Bruce Momjian	43f6388931	pg_test_fsync: expand ops/sec display Expand ops/sec by two digits to maintain alignment on servers with fast I/O subsystems, e.g. can now display < 10M ops/sec with consistent alignment.	12 years ago
Heikki Linnakangas	b5ed21998c	Fix pg_test_fsync, broken by xloginsert scaling patch. I didn't realize that ALIGNOF_XLOG_BUFFER was used in pg_test_fsync.	12 years ago
Bruce Momjian	06b804377c	Remove undocumented -h (help) option The -h option was not supported by many tools, and not documented, so remove them for consistency from pg_upgrade, pg_test_fsync, and pg_test_timing.	12 years ago
Bruce Momjian	095018bc32	pg_test_fsync: update output to show usecs/op clearer	13 years ago
Tom Lane	3c07fbf40b	Use pqsignal() in contrib programs rather than calling signal(2) directly. The semantics of signal(2) are more variable than one could wish; in particular, on strict-POSIX platforms the signal handler will be reset to SIG_DFL when the signal is delivered. This demonstrably breaks pg_test_fsync's use of SIGALRM. The other changes I made are not absolutely necessary today, because the called handlers all exit the program anyway. But it seems like a good general practice to use pqsignal() exclusively in Postgres code, now that we have it available everywhere.	13 years ago
Tom Lane	70ec2f8f43	Improve the documentation about commit_delay. Clarify the docs explaining what commit_delay does, and add a recommendation about a useful value for it, namely half of the single-page fsync time reported by pg_test_fsync. This is informed by testing of the new-in-9.3 implementation of commit_delay; in prior versions it was far harder to arrive at a useful setting. In passing, do some wordsmithing and markup-fixing in the same general area. Also, change pg_test_fsync's default time-per-test from 2 seconds to 5. The old value was about the minimum at which the results could be taken seriously at all, and so seems a tad optimistic as a default. Peter Geoghegan, reviewed by Noah Misch; some additional editing by me	13 years ago
Bruce Momjian	bd9c8e741b	Move long_options structures to the top of main() functions, for consistency. Per suggestion from Tom.	13 years ago
Tom Lane	427fd88552	Fix unportable format string. Per compiler warning.	13 years ago
Simon Riggs	82e429794b	Add microsecs/op display to pg_test_fsync utility e.g. fsync 2103.613 ops/sec ( 475 microsecs/op) Peter Geoghegan	13 years ago
Bruce Momjian	927d61eeff	Run pgindent on 9.2 source tree in preparation for first 9.3 commit-fest.	13 years ago
Bruce Momjian	388c2f9325	Fix pg_test_fsync Win32 problems reported by the build farm; add comments about the alarm method used on Win32.	14 years ago
Bruce Momjian	7ae2db1d1e	Try to get pg_test_thread to compile on Windows by using a sleeper thread.	14 years ago
Bruce Momjian	0a8396e35e	Change contrib/pg_test_fsync to control tests in terms of seconds per test, rather than a number of test cycles. Changes -o/cycles option to -s/seconds.	14 years ago
Bruce Momjian	2bbd88f8f8	Improve labeling of pg_test_fsync open_sync test output.	14 years ago
Robert Haas	ab7d4213f9	If pg_test_fsync is interrupted, clean up the temp file. Marti Raudsepp, with additional paranoia by me.	14 years ago
Peter Eisentraut	3a8dcd9a1f	Put pg_test_fsync --help and --version output in line with conventions Foremost, it should go to stdout.	15 years ago
Peter Eisentraut	001cbb145f	Avoid unused variable warnings for certain configurations	15 years ago
Bruce Momjian	bf50caf105	pgindent run before PG 9.1 beta 1.	15 years ago
Bruce Momjian	303b7fcd10	Modify pg_test_fsync to match the behavior of git head in regards to O_DIRECT behavior.	15 years ago
Tom Lane	629b3af27d	Convert contrib modules to use the extension facility. This isn't fully tested as yet, in particular I'm not sure that the "foo--unpackaged--1.0.sql" scripts are OK. But it's time to get some buildfarm cycles on it. sepgsql is not converted to an extension, mainly because it seems to require a very nonstandard installation process. Dimitri Fontaine and Tom Lane	15 years ago
Bruce Momjian	4fec63f94e	Per Peter E, use 'kB' for kilobyte, not 'K'.	15 years ago
Bruce Momjian	00869024cb	In pg_test_fsync, use K(1024) rather than k(1000) for write size units.	15 years ago
Bruce Momjian	64bc872761	Adjust pg_test_fsync to always do XLOG_BLCKSZ-sized writes, rather than always 8k writes, per suggestion from Tom. Also adjust open_sync output layout.	15 years ago
Bruce Momjian	9dd7933937	Use XLOG_BLCKSZ in pg_test_fsync, rather than our own define, but verify it is 8k as expected.	15 years ago
Bruce Momjian	9fc0192283	In test_open_sync(), writes kilobytes as intended, not by bytes.	15 years ago
Tom Lane	37eb2cd4ad	More pg_test_fsync fixups. Reduce #includes to minimum actually needed; in particular include postgres_fe.h not postgres.h, so as to stop build failures on some platforms. Use get_progname() instead of hardwired program name; improve error checking for command line syntax; bring error messages into line with style guidelines; include strerror result in die() cases.	15 years ago
Tom Lane	3ae28ce8c4	Suppress unused-variables warning when OPEN_SYNC_FLAG isn't defined. Per buildfarm.	15 years ago
Tom Lane	cb38ab6d3b	More pg_test_fsync cleanup. Un-break Windows build (I hope) by making the HAVE_FSYNC_WRITETHROUGH code match the backend. Fix incorrect program help message. static-ize all functions.	15 years ago
Tom Lane	bc616703e8	Clean up pg_test_fsync commit. Actually rename the program, rather than just claiming we did. Hook it into the build system. Get rid of useless dependency on libpq. Clean up #include list and messy whitespace.	15 years ago
Bruce Momjian	b35bfcae93	Update C banner on new pg_test_fsync file.	15 years ago
Bruce Momjian	606a3d54fc	Move test_fsync to /contrib.	15 years ago
