[QUOTE=LaurV;611117]
So, again, [B]what was that trick to run yafu in such a way that it doesn't compress the rels.dat file?[/B]
[/QUOTE]

Sorry for your troubles... I think you have to build msieve with the NO_ZLIB=1 option during make. That's how I build mine and I've never had relations compressed. I'm assuming you are building your own copy and not using my provided windows version.

That said, I'm not sure how you are getting both compressed and uncompressed relations in a single file.

Checked in new update and new windows exe:

Why does yafu remove entry from batchfile when i manually interrupt yafu wuth ctrl+c?

[QUOTE=kotenok2000;611135]Why does yafu remove entry from batchfile when i manually interrupt yafu wuth ctrl+c?[/QUOTE]

It removes lines after they are completed... it doesn't check that they were completed successfully.

I've always been on the fence about whether it should remove lines at all... on the one hand it's nice to know where you are in the process if something gets interrupted (e.g., power outage, in which case the line wouldn't be removed). On the other there are situations like this that are difficult to handle.

Since I don't want to deal with difficult situations I will probably just get rid of the removing-lines-as-they-finish feature unless there are strong opinions about keeping it.

[QUOTE=bsquared;611129]That said, I'm not sure how you are getting both compressed and uncompressed relations in a single file.[/QUOTE]
I don't. They are all compressed. But the machines run other things too, and in a not very stable environment, and the relations files get HUUGE. Sometimes a chunk inside of such a file is damaged, and yafu/gzip can not go behind of it. In a not-compressed file the things would be as easy as deleting few lines of text, with a text editor that can open such large files, or sometimes, not even that, because yafu will just skip lines with the bad relations. Also, when the computer crashes and rels0, rels1, ... rels_n (which are always uncompressed) remain hanging, on a not-compressed environment I could concatenate all these files to the rels.dat with a simple DOS copy command, and salvage the relations, before resuming the sieving. That is why my pledge for a non-compressed dat file. With a compressed dat file, I can not do any of those, and editing the file when things crash is more tedious (as explained in the previous post, something the "normal" user, who doesn't eat hex and binary for breakfast as we eat, can not do). The only disadvantage of an uncompressed dat file would be the larger size, and a bit longer time to read the relations when filtering (the relations are read from disk, as opposite to the zipped file which is decompressed in ram, faster), but nowadays everybody has large disks with lots of free space, and the additional 5-10 minutes, 3 or 4 times per day, won't be an issue.

I am using executable yafu, not compiled by myself. Which compressed the relations. I remember now that you told me once about recompiling msieve, but that I never did...

[QUOTE=bsquared;611137]I will probably just get rid of the removing-lines-as-they-finish feature unless there are strong opinions about keeping it.[/QUOTE]I have a strong preference to keep it for my own use. If you want to disable that by default then please leave the code in there behind a [c]--auto-remove-batch-lines[/c] or similar switch, please.

To recover data from a damaged .gz file try gzrecover. My script to recover from rubbish in relations from NFS@Home uses:
[code]
gzrecover -p $GZ | remdups 1250 -v >$DAT
[/code]

$GZ is file to process.
$DAT is where to put the recovered relations.

Just ran into something in today's v2.09 that I haven't seen before:[code]=== Starting work on batchfile expression ===

(The ECM executable does exist there, I think it just couldn't open it due to too many open files. And of course [c]factor.log[/c] does exist.)
I would suggest that "too many open files" should be a fatal error and YAFU should simply exit at that point rather than looping.
The screen output would just keep overwriting the [c]ecm: xx/74 curves on C73[/c] line over and over, however factor.log seemed to contain a full/normal run log for repeated factoring:[code]08/10/22 17:07:55, ****************************

How many entries does your batchfile have? I'm wondering if something isn't getting closed properly when looping over batchfile entries.

[QUOTE=bsquared;611176]How many entries does your batchfile have? I'm wondering if something isn't getting closed properly when looping over batchfile entries.[/QUOTE]I process batches of 100 at a time, submit results, fetch new, re-launch YAFU against the next batch.

I've done this successfully for long periods with v1.34.5 but only just started this on YAFU 2.09 today because the [c]-batchfile[/c] option was broken until this morning.

I'm not fully convinced that it's a YAFU-error rather than a Windows-error, just that YAFU's handling of the error condition should be better.
