git submodule reference support in LXR
-
This is not at all a patch submission. Question should go either to "Feature requests" if you have a good specification for it (a description of the initial context and a suggestion about how to handle it) or to "Discussion"/lxr-general. And it is not a bugfix as it does not address any open bug report. I close the ticket as inappropriate. Please ask in "Discussion"/lxr-general where it seems fit.

Hi, Am using GIT type of source project, is LXR support the git submodule reference ?

git submodule reference support in LXR
-
A lot of effort has been invested in LXR configuration process. The present release has a configuration script configure-lxr.pl which dramatically simplifies the task. For a simple tree, it is a matter of less than one minute, compared to the former tedious manual configuration of lxr.conf. Only for that, you should upgrade. There are also lots of new features and an impressive performance boost in generating the cross-references. Not the least, there is a comprehensive manual (albeit too verbos...

Out of curiosity, which LXR version was installed on your lost server?

I still have a copy of swish-e 2.4.7 and I can send it to you but I rather recommend using Glimpse for source tree indexing. Swish-e will hit on the file without any detail. Glimpse is more accurate as it returns file + line number. From personal experience, Swish-e is a tool for indexing HTML sites where the relevant information is the page containing the queried text and your browser will display the page. Glimpse returns the line number and LXR can immediately scroll to the line of interest. This...

Yep. LXRSwishe is a backup plan. We lost our server and I have to rebuild it. I'm doing a trial on openGROK at the moment. but if that doesn't pan out, we may return to LXR/Swish-e. I very much appreciate your reply.

Unable to tell. Does the error really contains $somepath ? With an explicit $ sign? In which case, this means template expansion went wrong, but there is no "somepath" variable in any template. Usually, this error is a consequence of a faulty lxr.conf configuration file or bad access rights on the source tree (a priori, I wave out this latter case).

There are two main sources of information: http://lxr.sourceforge.net (redirected to the https: site) the User's Manual downloadable from the File tab, doc folder The first one contains pages about installation and the third step is called Configuration. This is where you customise LXR after having installed it to apply it against your source code tree. This is very concise information. Extensive information is given in the User's Manual.

Shuwei Ye modified a comment on discussion lxr-general
Dear LXR developers, The default ctags used in Linux system is Exuberant Ctags (v5.8). And its development has stopped since 2009. Should LXR switch to use the forked ctags, Universal Ctags? It has many improvements, and new features/languages added. I tried it and found the LXR configuration works fine with it except the kind letter 'F' used for SQL2 in the file templates/ectags.conf, because the kind letter 'F' is reserved in the Universal Ctags. And LXR could make use of the new development in...
-
Thanks for drawing my attention on this. This is a very good idea. As you noticed, Exuberant Ctags is ageing. I'll evaluate this. But be patient, I am presently on a heavy project which is accumulating delays. So it might be some months before I issue a new release. Note that LXR does not provide Ctags which must be installed by users. Consequently, if Universal Ctags works seamlessly in the present LXR, don't hesitate to use it as a replacement.

unparenthesized multiple regular image file patterns

I didn't understand your point and you're awfully right. Shame on me! Your fix is the correct one. Thanks for report the bug and providing a fix. I'll incorporate it in the next release.
-
Sorry, again I missed the backslash \ in the ful expanded expression. Without a parenthesis, the full expanded regular expression would become '\.bitmap|bmp|gif|icon?|jp2|jpe?g|pjpe?g|png|svg|tiff?|xbm|xpm$' Thus it could match any string containing ".bitmap", "gif" or "tif", or string ending with "xpm", right? Best, Shuwei
-
Hi Andre-Littoz, Sorry, when I copied the line onto the bug report page, the backslach \ was somehow removed by the system? Since the value graphicfile in the configuration file lxr.conf is set to 'bitmap|bmp|gif|icon?|jp2|jpe?g|pjpe?g|png|svg|tiff?|xbm|xpm' Without a parenthesis, the full expanded regular expression would become '.bitmap|bmp|gif|icon?|jp2|jpe?g|pjpe?g|png|svg|tiff?|xbm|xpm$' Thus it could match any file with an extension ".bitmap", or any string containing "gif" or "tif". etc, right?...

In source line #382, the "dot" is escaped as my $isgraphic = $pathname =~ m/\.$config->{'graphicfile'}$/; If this is not the case, "dot" means "any character" and, indeed, tif, gif or any other extension string can be recognised in last position ($ marker) without being necessarily an extension by itself. Check the reverse solidus \ precedes the dot in your copy. Your proposed fix is not the right syntax. Enclosing the variable name in parentheses only creates a capture group. In this case, the (...

unparenthesized multiple regular image file patterns

If it works "locally" and you get 401 Forbidden from the LAN, it is a matter of 1) Apache security, 2) firewall configuration or 3) SELinux (security enhancements on Linux) protections. Th <ifmodule> you removed has no effect because you have ModPerl installed and the block is effective only when ModPerl is not installed. File .htaccess has a complex conditional data flow to cope automatically with the various possible Apache configurations so that user needs not care for that aspect of installation....

genxref: error when pêrmuting glimpse index files
-
The cause is not in the mv itself. If mv command is reverted, bug #275 reoccurs. What is really needed is to prevent extra directories from being created in the temporary indexing directory. For that, the cp command used to allow incremental indexing must be corrected. The present cp -r <index_dir>/<version> <tempd_dir> always creates a version/ subdirectory resulting in the form of the final mv command. cp must be modified to only copy the index files, but those are "hidden" files (name starting...

Žygimantas Matonis posted a comment on ticket #276
We are using docker container to deploy lxr. Unfortunately, if I blindly overwrite to verions 2.3.3, genxref fails to index new changes. Everything else works. This is the main issue preventing me from upgrade.
-
Released 2.3.4 with bug fix Thanks for reporting the bug. I'd advise you to update to latest release because all releases prior to 2.3.1 are plagued by a major vulnarability risk. DB schema did not change, you can substitute LXR source and don't need to reindex tree.

I confirm that after replacing Lang.pm with your version in 2.2.1, path generation works as expected with various type of paths ('//////', './' '../').
-
I've pushed a patch to the git repository. It works for me but my test is quite artificial. Could you test it on your real tree? Note: just substitute Lang.pm and restart the web server. Empty the caches in the browser for added reliability. No need to reindex. If it works fine also for you, I'll upload a fixed release.

Lang.pm: fix for bug 276, endless loop on multiple path separator

Everything is working fine with single seperator. The patch needs some improvement procesing '//' though (but at least it does not hang). http://snpy.in/ZeAGiZ
-
LXR goes in to infinite loop if '#include path//to/src.h' is found in source code.
-
The double slash is an excellent reason for the bad behaviour. Can you confirm that everything works fine with single / separator? I had similar problems in other language scanners but never thought to check C/C++ (because they're so heavily used in cross-referencing the Linux kernel).

Just released new 2.3.3 version to fix this bug (and another one with event Apache MPM module). Download it and replace your existing LXR root directory. Backup first lxr.conf and reinstall it. This will save you the configuration step. Run genxref with --reindexall option to get rid of all spurious subdirectories. For the record: this bug plagues releases 2.2.0 to 2.3.2.

templates/Apache/htaccess-generic: handle event MPM module
-
I found the culprit. When I modified genxref to allow uninterrupted service on huge trees (i.e. users can still access the LXR service while reindexing the tree, which lasted in this cases up to 5 hours), I enabled glimpseindex incremental mode. Since it is incremental, I make a copy of the glimpse databases and indexing occurs on this copy, not disturbing live LXR service. When this is done, the new databases are substituted for the older ones. This is where I made a mistake: I used a "standard"...
-
There's nothing weird in your lxr.conf, it is fully "standard". Since I don't understand this strange behaviour, I looked at my own glimpse directory and found the same bug (which I never noticed because the glimpse directory are usually hidden). I investigate and report back here. Thanks for notifying this bug.

Paramjot Oberoi posted a comment on ticket #275
Attached my lxr.conf.
-
I frequently call genxref several times in a row and don't get this erroneous behaviour. The gimpse directories are created only if they don't exist. Consequently, something in your configuration causes genxref to think they are not present. Please attach your lxr.conf so that I can study it.
