Stop random garbage in firebird.msg's bytes 8 to 11
some cleanup
Since we already have the define ISC_STATUS_LENGTH for the the length of
the status vector, we should use it! Replaced 'status[20]' with
'status[ISC_STATUS_LENGTH]'.
Replaced the different symbolic names for the maximum length of a path
(MAX_PATH, MAX_PATH_LENGTH, MAXPATHLEN) with one uniq symbol MAXPATHLEN.
o autoconf v2.53 and later is now required to generate configure
(sorry, but it makes many tasks easier)
o improved tests for mmap, socklen_t and offt_64
o added tests for atexit, on_exit, (v)fork, set(p)grp, setpgid and flock
o added test for the keyword 'volatile'
o fixed errors in configure.in
o updated config.h.in and autoconfig_msvc.h (the latter may be incorrect)
o replaced VOLATILE by volatile
o removed SETPGRP and ATEXIT
o replaced NO_FLOCK by HAVE_FLOCK
o SIG_FPTR cleanup
o vfork cleanup
in dialect 3 only.
2. BREAK statement has been disabled in triggers (like EXIT) because of the known
BLR limitations. I hope it can be safely used in stored procedures though, hence
I'd prefer to have it officially documented.
3. More complete implementation of the GROUP BY clause. You can group by internal
functions and have ability to use more complex grouping conditions than before.
By Arno Brinkman.
4. Allowed declaring and defining local variables at the same time.
By Claudio Valderrama.
Syntax: declare [variable] <var_name> <var_type> [{= | default} <default_value>]
5. Allowed ordinals to be used in the GROUP BY clause (like ORDER BY).
By Arno Brinkman.
Example: select extract(month from order_date), sum(order_sum) from orders group by 1
6. The first approach to the ALTER VIEW statement. Only high-level implementation so far.
A lot of work in dfw.epp, metd.epp, etc. still required.
By Dmitry Yemanov.
