I can see only two ways for those two sentences to be true at once, but it’s unclear which is the case from the way you phrased it: 1. The tip of trunk and *only* the tip of trunk exhibits the problem behavior. 2. Every checkin after 2.6 exhibits it. Which is it? If the problem first appeared with [76800769], the fix drh checked in to clean up the dangling journal files you were reporting, then I wonder if the delay is waiting out some SQLite lock. Windows’ native locking behavior is much more restrictive than the default on pretty much every other platform, so I wonder if the new shutdown code path created a temporary deadlock that gets broken by a SQLite timeout. Try backing that checkin out to see if the prior problem (dangling journal files) reappears, while the delay also goes away: fossil up trunk # back out from the bisect fossil revert # just to be sure fossil merge --backout 76800769 Then build and test. ___ fossil-users mailing list fossil-users@lists.fossil-scm.org http://lists.fossil-scm.org:8080/cgi-bin/mailman/listinfo/fossil-users
[fossil-users] Delay with `fossil ui' (related to backoffice processing?)
I've noticed something with the current tip version of Fossil (on Windows): I see random delays for the `fossil ui' command, i.e. the web browser is opened at once, but is displaying the loading/busy indicator and a blank page for some time, before the default web page finally appears: http://localhost:8080/timeline?c=current When repeatedly entering `fossil ui' from the command prompt, followed by immediately closing the web browser as soon as the /timeline web page is displayed, then hitting Ctrl+C to stop the Fossil web server, and restarting the cycle by running `fossil ui' again, the delay seems to appear with every 5th to 10th cycle. During the delay, I can see two fossil.exe processes with `tasklist | findstr fossil', whereas with `fossil ui' without the delay, there's only one fossil.exe process. The %TEMP% directory has 3 or more files appearing instantaneously at the beginning of the delay, named fossil_server_P8080_0N_xxx.txt, with N being low numbers, and xxx being 'in', 'out', and 'cmd', containing the HTTP request and response, and a file/IP address list. When terminating the delayed `fossil ui' server (responds to Ctrl+C) and immediately relaunching it, it is as fast as usual, without any delay. The delay takes approximately 60 seconds, and after that the HTTP request completes normally with the display of the /timeline web page, and the temporary files are cleared. I tried to find a "last good" version by means of "bisecting", but unfortunately no success, so far. All I can say is that the delay never appears with Fossil version 2.6 [9718f3b078] 2018-05-04 12:56:42 UTC, the binary for Windows downloaded from the Fossil web site. My tests were on Windows 10.0.17134.167 (64-bit), with MSVC 19.14.26430 (32-bit). --Florian ___ fossil-users mailing list fossil-users@lists.fossil-scm.org http://lists.fossil-scm.org:8080/cgi-bin/mailman/listinfo/fossil-users

I think I found it: https://www.mail-archive.com/fossil-users@lists.fossil-scm.org/msg27269.html There's a call to fossil_exit() from within a db_step()...db_finalize() block, and calling fossil_exit() only after db_finalize() fixed it. There's been some changes to fossil_exit() in the meantime, I'll check these, and report back here. > I find it odd that some people get so itchy over DB concurrency and > such with Fossil when highly active projects might have 40 or so > commits per day. I'm not worried by this. Stephan just wondered if a shared cookie database may be prone to locks contention, if I got him right. I'd assume the main bottleneck to be high-frequency, read-only, no-login web access (for a renowned project), in which case the cookie database doesn't even need to be attached, and not the frequency of commits. --Florian ___ fossil-users mailing list fossil-users@lists.fossil-scm.org http://lists.fossil-scm.org:8080/cgi-bin/mailman/listinfo/fossil-users
