workaround for the abort
no abort and more informative version_XXX file |
||
I'm beginning to think that what happens here is that the registry/itemrepository somehow tries to write 2 different version formats to file, which leads to an open failure if there's a runtime version mismatch.
The reason I think that is that I see the timestamps change on both version files (and curiously this session is the only one where that happens).

```
It would seem that the older tag file came from the kdev-python plugin which I had NOT updated to 5.3.3 . It never occurred to me that this might be necessary, and I think users (even) less involved with KDevelop development than I will think of it even less.
Would it be an idea to let the plugin disable itself if it detects that the current DUChain version is not the same as the one it was built against?
Anyway, updating the plugin did NOT solve my crashing issue.
Edit: I meant "upgraded TO KF5 Frameworks 5.60.0", FROM 5.52.0 . I observe the same issue in the 5.3.3 app image, including the double version tag file: ``` > ~/Desktop/Downloads/KDevelop-5.3.3-x86_64.AppImage libEGL warning: DRI2: failed to open i965 (search paths /usr/lib64/dri) libEGL warning: DRI2: failed to open swrast (search paths /usr/lib64/dri) libEGL warning: DRI2: failed to open i965 (search paths /usr/lib64/dri) libEGL warning: DRI2: failed to open swrast (search paths /usr/lib64/dri) kdevelop.plugins.git: couldn't find the git root for QUrl("file:///opt/local/portia-site-ports") kdevelop.plugins.git: couldn't find the git root for QUrl("file:///opt/local/portia-site-ports") kdevelop.plugins.git: couldn't find the git root for QUrl("file:///opt/local/portia-site-ports") failed to open a repository /tmp/.mount_KDevelOgKjbS/AppRun: line 36: 28348 Aborted kdevelop $@ Exit 134 > ll -htr ~/.cache/kdevduchain/kdevelop-\{c241ebeb-91a8-4054-a7f4-ef33efe8fd99}/ total 4.6M 22642 33K drwxr-xr-x 33 bertin bertin 33 Jul 22 16:55 ../ 348217 512 -rw-rw-r-- 1 bertin bertin 0 Jul 22 16:56 version_84083201 347974 512 drwxrwxr-x 2 bertin bertin 4 Jul 22 16:57 topcontexts/ 348216 512 -rw-rw-r-- 1 bertin bertin 32 Jul 22 16:57 Persistent Declaration Table_dynamic 348215 201K -rw-rw-r-- 1 bertin bertin 2.4M Jul 22 16:57 Persistent Declaration Table 347971 4.5K -rw-rw-r-- 1 bertin bertin 328 Jul 22 16:57 Code Model_dynamic 347970 613K -rw-rw-r-- 1 bertin bertin 3.7M Jul 22 16:57 Code Model 348208 512 -rw-rw-r-- 1 bertin bertin 8 Jul 22 16:57 Use Map_dynamic 348207 8.5K -rw-rw-r-- 1 bertin bertin 2.0M Jul 22 16:57 Use Map 347835 512 -rw-rw-r-- 1 bertin bertin 8 Jul 22 16:57 Php Completion Code Model_dynamic 347834 33K -rw-rw-r-- 1 bertin bertin 2.1M Jul 22 16:57 Php Completion Code Model 347720 512 -rw-rw-r-- 1 bertin bertin 8 Jul 22 16:57 Definition Map_dynamic 347719 8.5K -rw-rw-r-- 1 bertin bertin 2.0M Jul 22 16:57 Definition Map 347833 512 -rw-rw-r-- 1 bertin bertin 8 Jul 22 16:57 String Index_dynamic 347832 657K -rw-rw-r-- 1 bertin bertin 3.5M Jul 22 16:57 String Index 348206 512 -rw-rw-r-- 1 bertin bertin 8 Jul 22 16:57 Importer Map_dynamic 348205 8.5K -rw-rw-r-- 1 bertin bertin 2.0M Jul 22 16:57 Importer Map 348204 512 -rw-rw-r-- 1 bertin bertin 4 Jul 22 16:57 Type Repository_dynamic 348203 121K -rw-rw-r-- 1 bertin bertin 2.2M Jul 22 16:57 Type Repository 348200 512 -rw-rw-r-- 1 bertin bertin 4 Jul 22 16:57 Qualified Identifier Repository_dynamic 348199 393K -rw-rw-r-- 1 bertin bertin 2.6M Jul 22 16:57 Qualified Identifier Repository 348202 512 -rw-rw-r-- 1 bertin bertin 4 Jul 22 16:57 Instantiation Information Repository_dynamic 348201 21K -rw-rw-r-- 1 bertin bertin 2.1M Jul 22 16:57 Instantiation Information Repository 348198 512 -rw-rw-r-- 1 bertin bertin 4 Jul 22 16:57 Identifier Repository_dynamic 348197 361K -rw-rw-r-- 1 bertin bertin 2.5M Jul 22 16:57 Identifier Repository 348214 512 -rw-rw-r-- 1 bertin bertin 4 Jul 22 16:57 file modification sets_dynamic 348213 21K -rw-rw-r-- 1 bertin bertin 2.1M Jul 22 16:57 file modification sets 348196 512 -rw-rw-r-- 1 bertin bertin 4 Jul 22 16:57 file modification repository_dynamic 348195 53K -rw-rw-r-- 1 bertin bertin 2.1M Jul 22 16:57 file modification repository 347831 512 -rw-rw-r-- 1 bertin bertin 8 Jul 22 16:57 Recursive Imports_dynamic 347830 25K -rw-rw-r-- 1 bertin bertin 2.1M Jul 22 16:57 Recursive Imports 348210 512 -rw-rw-r-- 1 bertin bertin 8 Jul 22 16:57 Environment Lists_dynamic 348209 37K -rw-rw-r-- 1 bertin bertin 2.1M Jul 22 16:57 Environment Lists 348212 512 -rw-rw-r-- 1 bertin bertin 8 Jul 22 16:57 Environment Information_dynamic 348211 45K -rw-rw-r-- 1 bertin bertin 2.1M Jul 22 16:57 Environment Information 348219 512 -rw-rw-r-- 1 bertin bertin 0 Jul 22 16:57 version_84083457 347839 512 -rw-rw-r-- 1 bertin bertin 20 Jul 22 16:57 parsing_environment_data 347838 512 -rw-rw-r-- 1 bertin bertin 46 Jul 22 16:57 Counters 348194 512 -rw-rw-r-- 1 bertin bertin 12 Jul 22 16:57 Comment Repository_dynamic 348193 2.0M -rw-rw-r-- 1 bertin bertin 8.8M Jul 22 16:57 Comment Repository 347840 512 -rw-rw-r-- 1 bertin bertin 0 Jul 22 16:57 available_top_context_indices 348192 8.5K drwxrwxr-x 3 bertin bertin 42 Jul 22 16:57 ./ ``` Created attachment 121676 [details]
workaround for the abort
It appears there is no hard need to abort but that instead you can keep running without side-effects.
Turns out this was a false alarm, it just took me way too long to get the idea to check who was using libKDevPlatformSerialisation. Sure enough I had a not-so-zombie KDevelop 5.3.2 process running which I thought I had quit before logging off (the 1st time after upgrading to 5.60.0). My issues started after logging in. Two things would probably have helped me think of this sooner: - using the hex version number in the version file, so I'd have seen an unexpected version_5030201 file. - storing the application PID in the file instead of keeping it empty. It's been a (potentially) interesting "experiment" though that has shown that the session can survive unexpected "failed to open registry" errors, i.e. that an immediate abort isn't required. Created attachment 121693 [details]
no abort and more informative version_XXX file
This implements the earlier workaround to prevent the abort(), and my idea to make the version_XXX file a bit more useful to understand the kind of issue I was confronted with. The number in the filename is stored in hex (so it becomes evident which KDevelop version created the file) and the file itself contains the application PIC.
Depending on feedback here I may clean this up where necessary and put it up for review on phab after the summer (and 5.4 release)

Application: kdevelop (5.3.3-1-g125259eab4) (Compiled from sources) Qt Version: 5.9.8 Frameworks Version: 5.60.0 Operating System: Linux 4.14.23-ck1-mainline-core2-rjvb x86_64 Distribution: Ubuntu 14.04.6 LTS -- Information about the crash: - What I was doing when the application crashed: In this case I had just quit KDevelop after it seemed to have started up correctly, to see if this time it wouldn't abort at some seemingly random moment. This abort has started occurring in a session that I've been using for years, without any clear reason why, sometimes during startup, sometimes at a random time when working, and now on exit. I upgraded my frameworks to 5.52.0 last week (but I don't think any KF5 FW. code is being used here) and upgraded to KDevelop 5.3.3 a day or two ago (but downgrading to the 5.3.2 version from just before the new release doesn't help). Setting a breakpoint just before the abort shows that the directory at m_path exists, and even the file that hosts the repository so I don't know (yet) what causes the failure. The directory contents just before it got deleted and the abort was raised (note the presence of TWO version files - is that normal?) ``` ll ~/.cache/kdevduchain/kdevelop-\{c241ebeb-91a8-4054-a7f4-ef33efe8fd99}/ total 1616 347010 9 drwxrwxr-x 2 bertin bertin 40 Jul 22 15:03 ./ 22642 33 drwxr-xr-x 33 bertin bertin 33 Jul 22 15:00 ../ 347039 1 -rw-rw-r-- 1 bertin bertin 48 Jul 22 15:03 available_top_context_indices 347043 49 -rw-rw-r-- 1 bertin bertin 2090754 Jul 22 15:03 Code Model 347044 5 -rw-rw-r-- 1 bertin bertin 328 Jul 22 15:03 Code Model_dynamic 346888 65 -rw-rw-r-- 1 bertin bertin 2083988 Jul 22 15:03 Comment Repository 346889 1 -rw-rw-r-- 1 bertin bertin 4 Jul 22 15:03 Comment Repository_dynamic 347037 1 -rw-rw-r-- 1 bertin bertin 46 Jul 22 15:03 Counters 347041 1 -rw-rw-r-- 1 bertin bertin 4 Jul 22 15:02 crash_counter 347026 69 -rw-rw-r-- 1 bertin bertin 2090754 Jul 22 15:03 Definition Map 347027 1 -rw-rw-r-- 1 bertin bertin 8 Jul 22 15:03 Definition Map_dynamic 347032 45 -rw-rw-r-- 1 bertin bertin 2173657 Jul 22 15:03 Environment Information 347033 1 -rw-rw-r-- 1 bertin bertin 8 Jul 22 15:03 Environment Information_dynamic 347030 49 -rw-rw-r-- 1 bertin bertin 2096224 Jul 22 15:03 Environment Lists 347031 1 -rw-rw-r-- 1 bertin bertin 8 Jul 22 15:03 Environment Lists_dynamic 347013 69 -rw-rw-r-- 1 bertin bertin 2097180 Jul 22 15:03 file modification repository 347014 1 -rw-rw-r-- 1 bertin bertin 4 Jul 22 15:03 file modification repository_dynamic 347045 69 -rw-rw-r-- 1 bertin bertin 2097180 Jul 22 15:03 file modification sets 347046 1 -rw-rw-r-- 1 bertin bertin 4 Jul 22 15:03 file modification sets_dynamic 347015 149 -rw-rw-r-- 1 bertin bertin 2179115 Jul 22 15:03 Identifier Repository 347016 1 -rw-rw-r-- 1 bertin bertin 4 Jul 22 15:03 Identifier Repository_dynamic 347022 57 -rw-rw-r-- 1 bertin bertin 2090754 Jul 22 15:03 Importer Map 347023 1 -rw-rw-r-- 1 bertin bertin 8 Jul 22 15:03 Importer Map_dynamic 347019 45 -rw-rw-r-- 1 bertin bertin 2179029 Jul 22 15:02 Instantiation Information Repository 347020 1 -rw-rw-r-- 1 bertin bertin 4 Jul 22 15:02 Instantiation Information Repository_dynamic 347038 1 -rw-rw-r-- 1 bertin bertin 20 Jul 22 15:03 parsing_environment_data 346588 61 -rw-rw-r-- 1 bertin bertin 2090754 Jul 22 15:03 Persistent Declaration Table 346589 1 -rw-rw-r-- 1 bertin bertin 32 Jul 22 15:03 Persistent Declaration Table_dynamic 347017 185 -rw-rw-r-- 1 bertin bertin 2179115 Jul 22 15:03 Qualified Identifier Repository 347018 1 -rw-rw-r-- 1 bertin bertin 4 Jul 22 15:03 Qualified Identifier Repository_dynamic 347011 69 -rw-rw-r-- 1 bertin bertin 2097180 Jul 22 15:03 Recursive Imports 347012 1 -rw-rw-r-- 1 bertin bertin 8 Jul 22 15:03 Recursive Imports_dynamic 347024 437 -rw-rw-r-- 1 bertin bertin 3027827 Jul 22 15:03 String Index 347025 1 -rw-rw-r-- 1 bertin bertin 8 Jul 22 15:03 String Index_dynamic 347021 81 -rw-rw-r-- 1 bertin bertin 2097180 Jul 22 15:03 Type Repository 346890 1 -rw-rw-r-- 1 bertin bertin 4 Jul 22 15:03 Type Repository_dynamic 347028 69 -rw-rw-r-- 1 bertin bertin 2090754 Jul 22 15:03 Use Map 347029 1 -rw-rw-r-- 1 bertin bertin 8 Jul 22 15:03 Use Map_dynamic 347047 1 -rw-rw-r-- 1 bertin bertin 0 Jul 22 15:03 version_84083201 347036 1 -rw-rw-r-- 1 bertin bertin 0 Jul 22 15:02 version_84083457 ``` Other sessions do not appear to be affected (yet).
