pgindent
========
This can format all PostgreSQL *.c and *.h files, but excludes *.y, and
*.l files.
1) Install pg_bsd_indent (see below for details).
2) Install entab (src/tools/entab/).
3) Change directory to the top of the build tree.
4) Remove all derived files (pgindent has trouble with one of the flex macros):
make maintainer-clean
Or:
git clean -fdx
5) Download the typedef file from the buildfarm:
wget -O src/tools/pgindent/typedefs.list http://buildfarm.postgresql.org/cgi-bin/typedefs.pl
(see http://www.pgbuildfarm.org/cgi-bin/typedefs.pl?show_list for a full list of typedefs,
also http://adpgtech.blogspot.com/2015/05/running-pgindent-on-non-core-code-or.html)
6) Run pgindent:
src/tools/pgindent/pgindent
7) Remove any files that generate errors and restore their original
versions.
8) Indent the Perl code using perltidy v20090616 (perltidy changes formatting
decisions, so older and newer versions are incompatible):
(
find . -name \*.pl -o -name \*.pm
find . -type f -exec file {} \; |
egrep -i ':.*perl[0-9]*\>' |
cut -d: -f1
) |
sort -u |
xargs perltidy --profile=src/tools/pgindent/perltidyrc
9) Do a full test build:
> run configure
# stop is only necessary if it's going to install in a location with an
# already running server
pg_ctl stop
run configure
make -C src install
make -C contrib install
run initdb
pg_ctl start
make installcheck-world
10) Remove Perl backup files after testing (*.bak)
---------------------------------------------------------------------------
BSD indent
----------
We have standardized on NetBSD's indent, and renamed it pg_bsd_indent.
We have fixed a few bugs which requre the NetBSD source to be patched
with indent.bsd.patch patch. A fully patched version is available at
ftp://ftp.postgresql.org/pub/dev.
GNU indent, version 2.2.6, has several problems, and is not recommended.
These bugs become pretty major when you are doing >500k lines of code.
If you don't believe me, take a directory and make a copy. Run pgindent
on the copy using GNU indent, and do a diff -r. You will see what I
mean. GNU indent does some things better, but mangles too. For details,
see:
http://archives.postgresql.org/pgsql-hackers/2003-10/msg00374.php
http://archives.postgresql.org/pgsql-hackers/2011-04/msg01436.php
---------------------------------------------------------------------------
Notes about excluded files
--------------------------
src/include/storage/s_lock.h and src/include/port/atomics/ are excluded
because they contain assembly code that pgindent tends to mess up.
src/include/snowball/libstemmer/ and src/backend/snowball/libstemmer/
are excluded because those files are imported from an external project,
not maintained locally, and are machine-generated anyway.
src/interfaces/ecpg/test/expected/ is excluded to avoid breaking the ecpg
regression tests. Several *.h files are included in regression output so
should not be changed.
---------------------------------------------------------------------------
Obsolete typedef list creation instructions
-------------------------------------------
To use pgindent:
1) Build the source tree with _debug_ symbols and all possible configure options
2) Install to /usr/local/pgsql
3) Install all contrib modules
4) Save a list of typedefs by running:
src/tools/find_typedef /usr/local/pgsql/bin /usr/local/pgsql/lib > /tmp/pgtypedefs
