to explicitly cast the output back to char before comparing it to a char
value, else we get the wrong result for high-bit-set characters. Found by
Rolf Jentsch. Also, fix several places where <ctype.h> functions were being
called without casting the argument to unsigned char; this is likewise
unportable, but we keep making that mistake :-(. These found by buildfarm
member salamander, which I will desperately miss if it ever goes belly-up.
that is shipped in the distribution, named libpq-dist.rc. This way the
build system doesn't get upset when a distributed file is forcibly
overwritten by during a normal build.
verify_peer_name_matches_certificate(), clarify some of the function's
variables and logic, and update a comment. This should make SSL
improvements easier in the future.
(or RETURNING), but only when the output name is not any SQL keyword.
This seems as close as we can get to the standard's syntax without a
great deal of thrashing. Original patch by Hiroshi Saito, amended by me.
work with the PQExpBuffer code instead of fighting it. This avoids an
unnecessary limit on message length and fixes the latent bug that
errorMessage.len wasn't getting set.
the patch for those features put its cleanup code into freePGconn() which is
really the wrong place. Remove redundant code from freePGconn() and add
comments in hopes of preventing similar mistakes in future.

are known to write on the socket sometimes and thus we are vulnerable to
being killed by the signal if the server happens to go away unexpectedly.

This bug has been there all along, but since the situation is usually
only of interest to developers, I chose not to back-patch the changes.
main code path for enlarging libpq's input buffer in one swoop when needing to
read a long data message. Without this, the code will double the buffer size,
read more data, notice it still hasn't got the whole message, and repeat till
it finally has a large enough buffer. Which wastes a lot of data-moving
effort and also memory (since malloc probably can't do anything very useful
with the freed-up smaller buffers). Not sure why this wasn't there already;
certainly the COPY data path is a place where we're quite likely to see long
data messages. I'm not backpatching though, since this is just a marginal
performance issue rather than a real bug.
ParameterStatus message can be sent during COPY OUT: it's definitely
possible, since COPY from a SELECT subquery can trigger any user-defined
function.
we need to be able to swallow NOTICE messages, and potentially also
ParameterStatus messages (although the latter would be a bit weird),
without exiting COPY OUT state. Fix it, and adjust the protocol documentation
to emphasize the need for this. Per off-list report from Alexander Galler.
Applied patch send by ITAGAKI Takahiro <itagaki.takahiro@oss.ntt.co.jp> to fix bug in connect statement if user name is a variable.
Also fixed test case that didn't detect this.
PQconnectionNeedsPassword function that tells the right thing for whether to
prompt for a password, and improve PQconnectionUsedPassword so that it checks
whether the password used by the connection was actually supplied as a
connection argument, instead of coming from environment or a password file.
Per bug report from Mark Cave-Ayland and subsequent discussion.
renumbering of encoding IDs done between 8.2 and 8.3 turns out to break 8.2
initdb and psql if they are run with an 8.3beta1 libpq.so. For the moment
we can rearrange the order of enum pg_enc to keep the same number for
everything except PG_JOHAB, which isn't a problem since there are no direct
references to it in the 8.2 programs anyway. (This does force initdb
unfortunately.)
Going forward, we want to fix things so that encoding IDs can be changed
without an ABI break, and this commit includes the changes needed to allow
libpq's encoding IDs to be treated as fully independent of the backend's.
The main issue is that libpq clients should not include pg_wchar.h or
otherwise assume they know the specific values of libpq's encoding IDs,
since they might encounter version skew between pg_wchar.h and the libpq.so
they are using. To fix, have libpq officially export functions needed for
encoding name<=>ID conversion and validity checking; it was doing this
anyway unofficially.
It's still the case that we can't renumber backend encoding IDs until the
next bump in libpq's major version number, since doing so will break the
8.2-era client programs. However the code is now prepared to avoid this
type of problem in future.
Note that initdb is no longer a libpq client: we just pull in the two
source files we need directly. The patch also fixes a few places that
were being sloppy about checking for an unrecognized encoding name.
machines about casts between pointers and integers of different sizes.
While they're harmless, we shouldn't expect users to have to go through
and figure that out for themselves.

Helps problem with older versions of OpenSSL that lacks error
stack functions and would show an incorrect error message for
file-not-found-or-not-openable. The problem may still exist for
other errors, but file open error is by far the most common one.
OpenSSL libraries --- just don't call them if they're not there. This
might possibly lead to misleading error messages, but we'll just have
to live with that.
This fixes potential crashes on old versions of OpenSSL and the requirement on
"Applink" in new versions when building with MSVC and using different
runtimes.
Dave Page with fixes from me.
duplicative -DFRONTEND flags from many Makefiles. We still need Makefile
control of the symbol in a few places that compile frontend-or-backend
src/port/ files, but it's a lot cleaner than before.

- Really prepare statements
- Added more regression tests
- Added auto-prepare mode
- Use '$n' for positional variables, '?' is still possible via ecpg option
- Cleaned up the sources a little bit
against a Unix server, and Windows-specific server-side authentication
using SSPI "negotiate" method (Kerberos or NTLM).
Only builds properly with MSVC for now.
PGconn. Invent a new libpq connection-status function,
PQconnectionUsedPassword() that returns true if the server
demanded a password during authentication, false otherwise.
This may be useful to clients in general, but is immediately
useful to help plug a privilege escalation path in dblink.
Per list discussion and design proposed by Tom Lane.
regression driver into two parts and reusing half of it. Required to
run ECPG tests without a shell on MSVC builds.
Fix ECPG thread tests for MSVC build (incl output files).

ecpglib supports it.
Change configure (patch from Bruce) and msvc build system to no longer require
pthreads on win32, since all parts of postgresql can be thread-safe using the
native platform functions.
- Made some chars const as proposed by Stefan Huehner <stefan@huehner.org>.
- Synced parser and keyword lists.
- Copied two token parsing from backend parser to ecpg parser.
- Also added a test case for this.
to_timestamp():
- ID for day-of-week
- IDDD for day-of-year
This makes it possible to convert ISO week dates to and from text
fully represented in either week ('IYYY-IW-ID') or day-of-year
('IYYY-IDDD') format.
I have also added an 'isoyear' field for use with extract / date_part.

where possible, and fix some sites that apparently thought that fgets()
will overwrite the buffer by one byte.
Also add some strlcpy() to eliminate some weird memory handling.
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".
suffix, to distinguish them from doubles. Make some function declarations
and definitions use the "const" qualifier for arguments consistently.
Ignore warning 4102 ("unreferenced label"), because such warnings
are always emitted by bison-generated code. Patch from Magnus Hagander.
Made this option mark the .c files, so the environment variable is no longer needed.
Created a special MinGW file with the special error message.
Do not print port into log file when running regression tests.
FormatMessage() (This should have been in 8.2.0, patched to 8.2.X and
HEAD):

FormatMessage of windows cannot consider the encoding of the database.
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....
The user in multi-byte country can try this.

Negotiation failure is only likely to happen if one side or the other is
misconfigured, eg. bad client certificate. I'm not 100% convinced that
a retry is really the best thing, hence not back-patching this fix for now.
Per gripe from Sergio Cinos.
which turns out to be a dominant part of the runtime in scenarios
involving lots of parse-time warnings (such as Stephen Frost's example
of an INSERT with a lot of backslash-containing strings). There's not
a whole lot we can do about the character-at-a-time scanning, but we
can at least avoid traversing the query twice.
return true for exactly the characters treated as whitespace by their flex
scanners. Per report from Victor Snezhko and subsequent investigation.
Also fix a passel of unsafe usages of <ctype.h> functions, that is, ye olde
char-vs-unsigned-char issue. I won't miss <ctype.h> when we are finally
able to stop using it.
an earlier discussion. Centralize assumptions about what libpq depends
on in one place in Makefile.global. I am unconvinced that this list
is complete, but since ecpg seems to have gotten along with just these
entries, we'll try it this way and see what happens.
cascaded first to days and only what is leftover into seconds. This
seems to satisfy the principle of least surprise given the general
conversion to three-part interval values --- it was an oversight that
these cases weren't dealt with in 8.1. Michael Glaesemann
builds all the files needed for its regression tests, but the tests
themselves fail because of diffs in the #line directives output by
ecpg itself. Not sure what to do about that.
