* New header varatt.h split off from postgres.hPeter Eisentraut2023-01-101-0/+1
| | | | | | | | | This new header contains all the variable-length data types support (TOAST support) from postgres.h, which isn't needed by large parts of the backend code.

* Add more efficient functions to pqformat API.Andres Freund2017-10-111-55/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | There's three prongs to achieve greater efficiency here: 1) Allow reusing a stringbuffer across pq_beginmessage/endmessage, with the new pq_beginmessage_reuse/endmessage_reuse. This can be beneficial both because it avoids allocating the initial buffer, and because it's more likely to already have an correctly sized buffer. 2) Replacing pq_sendint() with pq_sendint$width() inline functions. Previously unnecessary and unpredictable branches in pq_sendint() were needed. Additionally the replacement functions are implemented more efficiently. pq_sendint is now deprecated, a separate commit will convert all in-tree callers. 3) Add pq_writeint$width(), pq_writestring(). These rely on sufficient space in the StringInfo's buffer, avoiding individual space checks & potential individual resizing. To allow this to be used for strings, expose mbutil.c's MAX_CONVERSION_GROWTH. Followup commits will make use of these facilities.

* Allow to avoid NUL-byte management for stringinfos and use in format.c.Andres Freund2017-10-111-9/+9
| | | | | | | | | | | | In a lot of the places having appendBinaryStringInfo() maintain a trailing NUL byte wasn't actually meaningful, e.g. when appending an integer which can contain 0 in one of its bytes. Removing this yields some small speedup, but more importantly will be more consistent when providing faster variants of pq_sendint etc. Author: Andres Freund Discussion: https://postgr.es/m/20170914063418.sckdzgjfrsbekae4@alap3.anarazel.de
* Replace most usages of ntoh[ls] and hton[sl] with pg_bswap.h.Andres Freund2017-10-011-29/+11
| | | | | | | | | | | | | | | | | All postgres internal usages are replaced, it's just libpq example usages that haven't been converted. External users of libpq can't generally rely on including postgres internal headers. Note that this includes replacing open-coded byte swapping of 64bit integers (using two 32 bit swaps) with a single 64bit swap. Where it looked applicable, I have removed netinet/in.h and arpa/inet.h usage, which previously provided the relevant functionality. It's perfectly possible that I missed other reasons for including those, the buildfarm will tell.

* Fix several mistakes around parallel workers and client_encoding.Robert Haas2016-06-301-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | Previously, workers sent data to the leader using the client encoding. That mostly worked, but the leader the converted the data back to the server encoding. Since not all encoding conversions are reversible, that could provoke failures. Fix by using the database encoding for all communication between worker and leader. Also, while temporary changes to GUC settings, as from the SET clause of a function, are in general OK for parallel query, changing client_encoding this way inside of a parallel worker is not OK. Previously, that would have confused the leader; with these changes, it would not confuse the leader, but it wouldn't do anything either. So refuse such changes in parallel workers. Also, the previous code naively assumed that when it received a NotifyResonse from the worker, it could pass that directly back to the user. But now that worker-to-leader communication always uses the database encoding, that's clearly no longer correct - though, actually, the old way was always broken for V2 clients. So disassemble and reconstitute the message instead. Issues reported by Peter Eisentraut. Patch by me, reviewed by Peter Eisentraut.

| | | | | | | | | | | encoding conversion of any elog/ereport message being sent to the frontend. This generalizes a patch that I put in last October, which suppressed translation of only specific messages known to be associated with recursive can't-translate-the-message behavior. As shown in bug #4680, we need a more general answer in order to have some hope of coping with broken encoding conversion setups. This approach seems a good deal less klugy anyway. Patch in all supported branches.

* Replace direct assignments to VARATT_SIZEP(x) with SET_VARSIZE(x, len).Tom Lane2007-02-271-2/+2
| | | | | | | | | | | Get rid of VARATT_SIZE and VARATT_DATA, which were simply redundant with VARSIZE and VARDATA, and as a consequence almost no code was using the longer names. Rename the length fields of struct varlena and various derived structures to catch anyplace that was accessing them directly; and clean up various places so caught. In itself this patch doesn't change any behavior at all, but it is necessary infrastructure if we hope to play any games with the representation of varlena headers. Greg Stark and Tom Lane
