A number of client programs have a "--progress" option that when printing
to a TTY, updates the current line by printing a '\r' and overwriting it.
After the last line, '\n' needs to be printed to move the cursor to the
next line. pg_basebackup and pgbench got this right, but pg_rewind and
pg_checksums were slightly wrong. pg_rewind printed the newline to stdout
instead of stderr, and pg_checksums printed the newline even when not
printing to a TTY. Fix them, and also add a 'finished' argument to
pg_basebackup's progress_report() function, to keep it consistent with
the other programs.
Backpatch to v12. pg_rewind's newline was broken with the logging changes
in commit cc8d415117 in v12, and pg_checksums was introduced in v12.

A few places calling fwrite and gzwrite were not setting errno to ENOSPC
when reporting errors, as is customary; this led to some failures being
reported as
"could not write file: Success"
which makes us look silly. Make a few of these places in pg_dump and
pg_basebackup use our customary pattern.

Includes some manual cleanup of places that pgindent messed up,
most of which weren't per project style anyway.
Notably, it seems some people didn't absorb the style rules of
commit c9d297751, because there were a bunch of new occurrences
of function calls with a newline just after the left paren, all
with faulty expectations about how the rest of the call would get
indented.

The defect suppressed a Standby Status Update message when bytes flushed
to disk had changed but bytes received had not changed. If
pg_recvlogical then exited with no intervening Standby Status Update,
the next pg_recvlogical repeated already-flushed records. The defect
could also cause superfluous messages, which are functionally harmless.
Back-patch to 9.5 (all supported versions).

pg_recvlogical merely called PQfinish(), so the backend sent messages
after the disconnect. When that caused EPIPE in internal_flush(),
before a LogicalConfirmReceivedLocation(), the next pg_recvlogical would
repeat already-acknowledged records. Whether or not the defect causes
EPIPE, post-disconnect messages could contain an ErrorResponse that the
user should see. One properly ends PGRES_COPY_OUT by repeating
PQgetCopyData() until it returns a negative value. Augment one of the
tests to cover the case of WAL past --endpos. Back-patch to v10, where
commit 7c030783a5bd07cadffc2a1018bc33119a4c7505 first appeared. Before
that commit, pg_recvlogical never reached PGRES_COPY_OUT.

When pg_basebackup -R is used, we inject standby.signal into the
tar file for the main tablespace. The proper thing to do is to pad
each file injected into the tar file out to a 512-byte boundary
by appending nulls, but here the file is of length 0 and we add
511 zero bytes. Since 0 is already a multiple of 512, we should
not add any zero bytes. Do that instead.
Patch by me, reviewed by Tom Lane.

The result of the query used to retrieve the WAL segment size from the
backend was not getting freed in two code paths. Both pg_basebackup and
pg_receivewal exit immediately if a failure happened on this query, so
this was not an actual problem, but it could be an issue if this code
gets used for other tools in different ways, be they future tools in
this code tree or external, existing, ones.

Since 0d8c9c1, pg_basebackup would generate an error if connected to a
backend version older than 12 where backup manifests are not supported.
Avoiding this error is possible by using the --no-manifest option.
This error handling could be confusing for some users, where patching a
backup script that interacts with multiple backend versions would cause
the addition of --no-manifest to potentially not generate a backup
manifest even for Postgres 13 and newer versions. As we want to
encourage the use of backup manifests as much as possible, this commit
silently disables manifests where not supported, instead of generating
an error.
While on it, rework a bit the code to make it more consistent with the
surroundings when generating the BASE_BACKUP command.

Herrera, Kyotaro Horiguchi, Tom Lane, David Steele, and me.

This commit prevents pg_basebackup from receiving backup_manifest file
when --no-manifest is specified. Previously, when pg_basebackup was
writing a tarfile to stdout, it tried to receive backup_manifest file even
when --no-manifest was specified, and reported an error.
Also remove unused -m option from pg_basebackup.
Also fix typo in BASE_BACKUP command documentation.

A manifest is a JSON document which includes (1) the file name, size,
last modification time, and an optional checksum for each file backed
up, (2) timelines and LSNs for whatever WAL will need to be replayed
to make the backup consistent, and (3) a checksum for the manifest
itself. By default, we use CRC-32C when checksumming data files,
because we are trying to detect corruption and user error, not foil an
adversary. However, pg_basebackup and the server-side BASE_BACKUP
command now have options to select a different algorithm, so users
wanting a cryptographic hash function can select SHA-224, SHA-256,
SHA-384, or SHA-512. Users not wanting file checksums at all can
disable them, or disable generating of the backup manifest altogether.
Using a cryptographic hash function in place of CRC-32C consumes
significantly more CPU cycles, which may slow down backups in some
cases.
A new tool called pg_validatebackup can validate a backup against the
manifest. If no checksums are present, it can still check that the
right files exist and that they have the expected sizes. If checksums
are present, it can also verify that each file has the expected
checksum. Additionally, it calls pg_waldump to verify that the
expected WAL files are present and parseable. Only plain format
backups can be validated directly, but tar format backups can be
validated after extracting them.

This commit changes pg_basebackup so that it specifies PROGRESS option in
BASE_BACKUP replication command whether --progress is specified or not.
This causes the server to estimate the total backup size and report it in
pg_stat_progress_basebackup.backup_total, by default. This is reasonable
default because the time required for the estimation would not be so large
in most cases.
Also this commit adds new option --no-estimate-size to pg_basebackup.
This option prevents the server from the estimation, and so is useful to
avoid such estimation time if it's too long.

An instance of PostgreSQL crashing with a bad timing could leave behind
temporary pg_internal.init files, potentially causing failures when
verifying checksums. As the same exclusion lists are used between
pg_rewind, pg_checksums and basebackup.c, all those tools are extended
with prefix checks to keep everything in sync, with dedicated checks
added for pg_internal.init.
Backpatch down to 11, where pg_checksums (pg_verify_checksums in 11) and
checksum verification for base backups have been introduced.

First, this code did not bother checking for a failure when calling
dup(). Then, per zlib, gzerror() returns NULL for a NULL input, which
can happen if passing down to gzdopen() an invalid file descriptor or if
there was an allocation failure.
No back-patch is done as this would unlikely be a problem in the field.

Add a new function ReceiveCopyData that does just that, taking a
callback as an argument to specify what should be done with each chunk
as it is received. This allows a single copy of the logic to be shared
between ReceiveTarFile and ReceiveAndUnpackTarFile, and eliminates
a few #ifdef conditions based on HAVE_LIBZ.
While this is slightly more code, it's arguably clearer, and
there is a pending patch that introduces additional calls to
ReceiveCopyData.
This commit is not intended to result in any functional change.

When maintaining or merging patches, one of the most common sources
for conflicts are the list of objects in makefiles. Especially when
the split across lines has been changed on both sides, which is
somewhat common due to attempting to stay below 80 columns, those
conflicts are unnecessarily laborious to resolve.
By splitting, and alphabetically sorting, OBJS style lines into one
object per line, conflicts should be less frequent, and easier to
resolve when they still occur.

Since the addition of fsync requests in bc34223 to make base backup data
consistent on disk once pg_basebackup finishes, each tablespace tar file
is individually flushed once completed, with an additional flush of the
parent directory when the base backup finishes. While holding a
connection to the server, a fsync request taking a long time may cause a
failure of the base backup, which is annoying for any integration. A
recent example of breakage can involve tcp_user_timeout, but
wal_sender_timeout can cause similar problems.
While reviewing the code, there was a second issue causing too many
fsync requests to be done for the same WAL data. As recursive fsyncs
are done at the end of the backup for both the plain and tar formats
from the base target directory where everything is written, it is fine
to disable fsyncs when fetching or streaming WAL.

The original placement of this module in src/fe_utils/ is ill-considered,
because several src/common/ modules have dependencies on it, meaning that
libpgcommon and libpgfeutils now have mutual dependencies. That makes it
pointless to have distinct libraries at all. The intended design is that
libpgcommon is lower-level than libpgfeutils, so only dependencies from
the latter to the former are acceptable.
We already have the precedent that fe_memutils and a couple of other
modules in src/common/ are frontend-only, so it's not stretching anything
out of whack to treat logging.c as a frontend-only module in src/common/.
To the extent that such modules help provide a common frontend/backend
environment for the rest of common/ to use, it's a reasonable design.
(logging.c does not yet provide an ereport() emulation, but one can
dream.)
Hence, move these files over, and revert basically all of the build-system
changes made by commit cc8d41511. There are no places that need to grow
new dependencies on libpgcommon, further reinforcing the idea that this
is the right solution.
