Thread: ecpg thread-safe descriptor
Here is a patch to fix thread-safety of SQL DESCRIPTOR in ecpg. The global variable 'all_descriptors' is split into per-thread vars. There was another idea of splitting into per-connection vars, but I did not do that because there are allocating descriptors before connection and deallocating after disconnection in the regression test. The attached descriptor.pgc is a test case for the issue. It is not included into regression test of ecpg. If this change is acceptable to be applied to HEAD, I'll start backporting recent fixes (prepared statement, memory allocation and descriptor) to 8.2 (and older versions if possible).

Are you sure we should backport this to 8.2 and earlier? It's fairly large changes, and not necessarily entirely straightforward (for example, the buildfarm is still partially broken from the earlier ones not being portable enough). I think this can be considered a "new feature" and not just a plain bugfix, so it should probably only go into HEAD. //Magnus

Almost portability issues come from Windows, but ecpg in 8.2 only support thread-safety on pthread, not on Win32. So backporting is easier than expected because we can neglect Windows. I want thread-safe ecpg *NOW* and cannot wait for 8.3 release... At any rate, I'll fix it at hand and report it if it works well. BTW, do we need to distribute ecpg with server (or client library) ? If it was a separate product, I think we will be able to maintain them more flexiblly, just like libpqxx or JDBC. Regards, --- ITAGAKI Takahiro NTT Open Source Software Center

I do not agree at all with this statement. IMO it's absolutely necessary that ecpg's parser is in sync with the backend's parser. So essentially we would not gain any flexibility as we'd have to release at the same time anyway.

That's the reason I recall for keeping it in there as well. Michael, any chance to consider the exports-from-libecpg issue I posted about the other day? //Magnus

Could you give me some details? I have to admit that I didn't follow this discussion as close as needed because I still have no Windows setup to test with myself. Which of course means I have no idea about the Windows build process at all.

I am very nearly ready to demand that ecpg as a whole be reverted to its state as of Saturday, with all the patches since then held for 8.4 development. At no point since Sunday morning has ecpg been passing buildfarm testing, and I see no activity indicating that it's about to get fixed. You guys are holding up beta release with work that by any legitimate definition is new-feature development, and shouldn't be under consideration at all at this point. regards, tom lane

It doesn't help to revert the patches if we still do not compile cleanly on MSVC. Or is it only the DLLMAIN thing that's holding us up? If so couldn't we just remove this function and call MSVC build not multithreaded? Also Takahiro (hope this is your first name :-)), could you please explain to us why DllMain is needed at all? it isn't needed on non-Windows systems it seems. As far as fixing things you're right.

Seems I got this mixed up. Once we enabled testing for ecpg we had some problems to be sorted out, but right now only the DllMain thing seems to be a problem. Since I do not know whether we really need DllMain could anyone please test whether ecpg builds correctly without it? We can then sort out how to fix the problem later on. AFAIRC (and hopefully I'm right this time) multithreading never worked under msvc so we might have to set thread-safety to disabled on these systems for ecpg for the time being.

It looks to me like we should not need it, if we instead add code to initialize the mutexes properly on Windows (a la the way it's done in libpq). I can prepare a patch, but I don't have the ability to test it on Windows --- will anyone be around who can, in an hour or so? regards, tom lane

There are two problems: 1) DllMain breaks the build *completely*. This is the really urgent one. This one broke 2 days ago or so. 2) Regression tests don't pass on MSVC anymore. This broke a while ago. I was working on fixing this, but now that the build is broken there isn't much I can do until that's fixed. > Since I do not know whether we really need DllMain could anyone please > test whether ecpg builds correctly without it?

We could move the initialization somewhere else, but it needs to be somewhere. Also, see http://archives.postgresql.org/pgsql-hackers/2007-10/msg00006.php for another comment on this. This changes more than just the threading stuff, but if it's something we want then this is a good time to do it. //Magnus

I can probably (but not certainly, so if someone else is around that'd be nice) get close enough to remote a windows box to test that a build passes, but remember that we can't really run the regression tests on msvc right now :-( //Magnus

Hm, I take that back --- the other reason it's there is as a kluge to avoid supporting pthread_once(). This code all looks pretty darn hokey, not to mention that it ought to be merged with libpq's pthread-win32.c, but fixing it seems not a one-hour proposition. >> AFAIRC (and hopefully I'm right this time) >> multithreading never worked under msvc so we might have to set >> thread-safety to disabled on these systems for ecpg for the time being. If it didn't work then this seems clearly new-feature-development. I think Magnus' idea of providing an exports list would be worth trying, if someone can try it promptly; failing that, we need to revert this patch. regards, tom lane

Well, ecpg was said to work with multithreading but didn't. However, since the patch works on most archs if indeed fixes some bugs on those archs. > I think Magnus' idea of providing an exports list would be worth trying, > if someone can try it promptly; failing that, we need to revert this > patch. Couldn't we just disable multithreading for Windows resp. MSVC? It appears to me that the rest of the patch is working as advertized.

Did we run regression tests at all before? Or did they never work and we just didn't notice because the buildfarm didn't run them? > Also, see > http://archives.postgresql.org/pgsql-hackers/2007-10/msg00006.php for > another comment on this.

There is no need to export all symbols. I always tried to keep the number of symbols that get exported but are not needed low. So this will give the best result possible.

I ran them manually, but then I thought the buildfarm did so I didn't bother doing it. Turned out I was wrong and it didn't, so we missed the breakage for a while. They were broken during the major update. I think it's as simple as changing the way ecpg is called (that was the first problem at least), so it's probably an easy fix. >> Also, see >> http://archives.postgresql.org/pgsql-hackers/2007-10/msg00006.php for >> another comment on this.

Yeah, it does seem to fix it. Can you put together explicit-export-list for the Unix case, using the way libpq does it (using an exports.txt file, and then the same Makefile rules as libpq uses). Once that's done I can deal with the MSVC part of that, but since I don't know exactly which symbols need to be exported... //Magnus

If Michael can put together an export list soon then we'll be in good shape. Michael: you should bump the major version number of ecpglib when you do this. Removing the not-officially-exported visible symbols *is* an ABI break. You may think there isn't anything depending on them, but remember how we thought that (twice) for libpq too. Bumping the major version number will be cheap insurance against complaints later. regards, tom lane

I brought the initialization routine from libpq and implemented pthread_once() using a lock that serializes all pthread_once calls. I don't have msvc build environment, but I hope it will fix the build failure on it. On another matter, this patch includes removing descriptors field in struct connection. This was my mistake in the previous fix of descriptors. Regards, --- ITAGAKI Takahiro NTT Open Source Software Center

I also renamed the functions that are not exported to make this job easier. Should there be a problem with this it should only be a missed rename.
