From 1d96c1b91a4b7da6288ee63671a234b557ff5ccf Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Wed, 23 May 2018 10:59:55 -0400 Subject: Fix incorrect ordering of operations in pg_resetwal and pg_rewind. Commit c37b3d08c dropped its added GetDataDirectoryCreatePerm call into the wrong place in pg_resetwal.c, namely after the chdir to DataDir. That broke invocations using a relative path, as reported by Tushar Ahuja. We could have left it where it was and changed the argument to be ".", but that'd result in a rather confusing error message in event of a failure, so re-ordering seems like a better solution. Similarly reorder operations in pg_rewind.c. The issue there is that it doesn't seem like a good idea to do any actual operations before the not-root check (on Unix) or the restricted token acquisition (on Windows). I don't know that this is an actual bug, but I'm definitely not convinced that it isn't, either. Assorted other code review for c37b3d08c and da9b580d8: fix some misspelled or otherwise badly worded comments, put the #include for where it actually belongs, etc. Discussion: https://postgr.es/m/aeb9c3a7-3c3f-a57f-1a18-c8d4fcdc2a1f@enterprisedb.com --- src/backend/storage/file/fd.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'src/backend/storage/file/fd.c') diff --git a/src/backend/storage/file/fd.c b/src/backend/storage/file/fd.c index 441f18dcf56..8dd51f17674 100644 --- a/src/backend/storage/file/fd.c +++ b/src/backend/storage/file/fd.c @@ -3552,8 +3552,8 @@ fsync_parent_path(const char *fname, int elevel) /* * Create a PostgreSQL data sub-directory * - * The data directory itself, along with most other directories, are created at - * initdb-time, but we do have some occations where we create directories from + * The data directory itself, and most of its sub-directories, are created at + * initdb time, but we do have some occasions when we create directories in * the backend (CREATE TABLESPACE, for example).
