backend/po, make update-po works strange

Kovacs Zoltan writes:

running "make update-po" in backend/po/ I'm always getting very short .po
files and the .pot file is also about 7K. It seems to be the fact that
xgettext gets text only from postgres.c and postmaster.c. What's the
problem? Version: beta3 and beta5 (I didn't try beta4 but it's certainly
the same).

Since the postgres.pot file has nearly 400 dependency files (all backend
source files), it is currently handled in an odd way. Observe this:

peter ~/pgsql/src/backend/po$ make init-po
find ./.. -name '*.c' -print >gettext-files
xgettext --foreign-user -ctranslator -D . -n -kelog:2 -kpostmaster_error -f gettext-files
mv messages.po postgres.pot

If the "find" somehow messes up you will get an incomplete .pot file.
Also note that there are no prerequisites declared for the file
"gettext-files". That is, if it's wrong or outdated you need to remove it
first.

Suggestions for improvement welcome.

I'm afraid the problem is that there are too few `gettext(...)'s in the
whole code in backend/. The file "gettext-files" is quite big: 10106 bytes
after each run of "make". I got the same result with "make init-po" and
"make update-po" (after "make maintainer-clean", of course). Perhaps the
original (>250K) .pot file was created with a different method...?

An example: parser/parse_agg.c contains an elog error at line 111 without
any gettext call. In opposite, postmaster/postmaster.c at line 290
contains an fprintf with a gettext call. Why the difference? Of course,
the second string will appear in postgres.pot and the first one
won't. File "gettext-files" contains both file.

Unfortunately this is only the first day I started to read the docs about
gettext, sorry...

TIA, Zoltan

The elog() strings are supposed to be picked up without any additional
marking. Sounds like you are using the wrong procedure for extracting
the strings. But I dunno what the right procedure is ...

Ah, you need to have GNU gettext 0.10.36 or later.

Seems like it would be somewhat better if a plain "make clean" removes
gettext-files, not only maintainer-clean. It's not like anyone hasn't
got "find", or even that "find" takes unreasonably long ...
