What's become of initdb's initial note about who you are? $ initdb The files belonging to this database system will be owned by user "postgres". This user must also own the server process. ... etc etc... The first two lines of printout don't seem to be in the "highly compatible" C version. regards, tom lane

Consider also the strong likelihood that the data directory's parent directory is owned by root, so that you do not have the ability to delete and recreate the data directory because you don't have write permission on its parent. The main reason initdb is set up to be able to start with an existing-but-empty data dir is exactly because creating that directory may have required permissions that initdb itself hasn't got. regards, tom lane

Windows has no concept of directory permissions at all? I thought the more recent versions had at least rudimentary permissions. regards, tom lane

Non-Win32 does rm -rf dir/*. I think we should forget about invoking rm as a subprocess at all, and just do the recursive directory walk and unlinks for ourselves. We already have code to do this for copy in copydir.c, and unlink would not be any longer. We will probably be forced into implementing database removal for ourselves rather than by 'rm' hacks anyway as soon as tablespaces come to pass; so why contort initdb's behavior for a very transient implementation savings? regards, tom lane

Here is a slightly modified version of Andrew's great work in making a C
version of initdb. Other than minor cleanups, the only big change was
to remove rmdir handling because we using rm -r and rmdir /s in
commands/dbcommands.c, so we might as use the same thing for initdb.c
rather than having code that traverses the directory tree doing 'rm'.
The other change was to remove the unlink code and instead use
port/dirmod.c's version.
It passes all the regression tests. I have also included a diff against
Andrew's version so you can see my changes. It seems Andrew had a very
current version of initdb. The only update he missed was the change to
test the number of connections before shared buffers --- I made that
change myself.
I would like to apply this in the next few days to HEAD before initdb.sh
drifts. We are no longer using the WIN32_DEV branch because all our
work is now in 7.5 head.

Andrew, I assume this was a new implementation of initdb, and not taken from an older initdb C implementation made by a company.

Good. I can do rmdir() in C in port/dirmod.c if we need it. Right now
we are doing system(rm/rmdir) in dbcommands.c so we should consistent.
Let's stay with system(rm/rmdir) and if it doesn't work as we expect, we
can add your rmdir() code and put it in port/dirmod.c.

Peter, I thought we add:
#endif /* port... */
only when the define covers many lines of code. This case:
#ifdef WIN32
some code
#endif
seems clearer than:
#ifdef WIN32
some code
#endif /* WIN32 */
Of course, if the code block is very large, a closing comment can
sometimes help. Personally, I don't like the comments anytime, but if
people like them on long blocks, I can understand that.

I am confused. The only change I made was to have the quotes appear
only on WIN32.
#ifndef WIN32
#define QUOTE_PATH ""
#else
#define QUOTE_PATH "\""
#endif
...
printf("\n"
"Success. You can now start the database server using:\n\n"
" %s/postmaster -D %s%s%s\n"
"or\n"
" %s/pg_ctl -D %s%s%s -l logfile start\n\n",
pgpath, QUOTE_PATH, pg_data, QUOTE_PATH,
pgpath, QUOTE_PATH, pg_data, QUOTE_PATH);
(I also merged multiple \n into a single line.) My logic was that
spaces in directory names are much more common on WIN32, so we should
display the quotes only on WIN32. Perhaps you read "\"" as "\\"?

Thanks for reviewing my work. I am surprised how small the new initdb.c
is. It is 50k vs 38k for initdb.sh. Of course, system_views.sql is
another 10k, but still, it is smaller than I thought, and quite clear.
Thanks.

The great part is that it look so much like our code, unlike the commerical port code I have seen for initdb in the past.

Recreating the directory only happens on WIN32, where rmdir doesn't allow you to only delete files and subdirectories and not the parent directory. Non-Win32 does rm -rf dir/*.

Again, recreate is only Win32. I just figured out how to do this on
Win32. We have to use 'del' rather than 'rmdir' to keep the directory:
New code is:
/*
* delete a directory tree recursively
* assumes path points to a valid directory
* deletes everything under path
* if rmtopdir is true deletes the directory too
*
*/
static bool
rmtree(char *path, bool rmtopdir)
{
char buf[MAXPGPATH + 64];
#ifndef WIN32
/* doesn't handle .* files */
snprintf(buf, sizeof(buf), "rm -rf '%s%s'", path,
rmtopdir ? "" : "/*");
#else
snprintf(buf, sizeof(buf), "%s /s /q \"%s\"",
rmtopdir ? "rmdir" : "del", path);
#endif
return !system(buf);
}

I ran some tests using XP "CMD" and found:
"C:\test"
and
"\test"
works but:
"test"
does not work. Since I see that the output always has a leading path, I
have modified the code to do:
printf("\nSuccess. You can now start the database server using:\n\n"
" %s%s%s/postmaster -D %s%s%s\n"
"or\n"
" %s%s%s/pg_ctl -D %s%s%s -l logfile start\n\n",
QUOTE_PATH, pgpath, QUOTE_PATH, QUOTE_PATH, pg_data, QUOTE_PATH,
QUOTE_PATH, pgpath, QUOTE_PATH, QUOTE_PATH, pg_data, QUOTE_PATH);
I am attaching the updated initdb.c file.

I think recreating the datadir if we didn't create it initially should be OK in that case, and it makes the code simpler. Not handling dot files in the Unix case should also be fine, as we know the directory was empty to start with and we don't create any. Regarding the #endif comments you removed - Peter had asked me to put them in. See http://archives.postgresql.org/pgsql-hackers/2003-10/msg00352.php You put a comment on canonicalise_path() asking if it is needed. The short answer is very much "yes". The Windows command processor will accept suitably quoted paths with forward slashes, but barfs badly with mixed forward and back slashes. (See recent discussion on hackers-win32).Removing the trailing slash on a path means we never get ugly double slashes. Feel free to put that info in as a comment if you think it is needed. The changes you made for the final message are not going to work for Windows - if pgpath or pg_data contain spaces we need quotes (even on Unix, although there most people know better than to put spaces in names). Also see above about mixed slashes. Also, putting a \ before pg_data will be nasty if it starts with a drive or network specifier - or even without (you might turn a directory specifier into a network drive specifier). It's just a message, though, and we shouldn't hold up for that - we can patch it to get it right. (Getting the path and slash thing working portably was by far the biggest headache in this project - the rest was just grunt work for the most part, although I learned a few interesting things.) Otherwise I'm fine with this. cheers andrew

Yes, I did. Sorry about that. But we also need to quote the path (the
most obvious place to put it after all is "C:\Program
Files\PostgreSQL"). In fact, that's more important than the data
location. Unfortunately, the Windows command processor barfs on multiple
quotes strings ;-(

More than rudimentary on the server versions.
I found this info at http://www.cs.wayne.edu/labPages/modes.htm :
Windows ACLs
Windows NT and Windows 2000 uses Access Control Lists or ACLs to
determine what operations a user may perform on a file. Windows ACLs
allow one to set permissions with finer control that does the Unix file
mode. For example, one can all[ow] a user to append data to a file as
opposed to overwiting the file. ACLs also allow one to permit specific
users to change the permissions on a file. Perhaps the biggest
difference is that ACLs allow us to accord permissions on a user-by-user
basis, rather than the three categories of users permitted by Unix file
systems.
This info applies to directories as well as plain files AFAIK
cheers

On Windows, pgpath is guaranteed to be a full path (see call to
expanded_path() ) exactly so it works inside quotes using the Windows
command processor.

The problem with this is that you now have 2 quoted strings. This is
exactly the problem that I solved inside initdb by passing pg_data via
the environment rather than on the command line. "help cmd" on XP gives
you this info:
If /C or /K is specified, then the remainder of the command line after
the switch is processed as a command line, where the following logic is
used to process quote (") characters:
1. If all of the following conditions are met, then quote characters
on the command line are preserved:
- no /S switch
- exactly two quote characters
- no special characters between the two quote characters,
where special is one of: &<>()@^|
- there are one or more whitespace characters between the
the two quote characters
- the string between the two quote characters is the name
of an executable file.
2. Otherwise, old behavior is to see if the first character is
a quote character and if so, strip the leading character and
remove the last quote character on the command line, preserving
any text after the last quote character.
It is amazingly brain dead and cost me hours and hours of grief trying
to work out WTF was going on.
Offhand I can't think of a simple guaranteed to work command line for
the Windows message.
In the last resort we might need to look at having initdb create a .bat
file or two for us.
:-(((

That should be avoided, because you'll have trouble recreating the original directory with all its properties such as ownership, permissions, etc., at least not without making the code anything but simpler. There might even be a situation were you are allowed to delete the directory but cannot create a new one. -- Peter Eisentraut peter_e@gmx.net
