Known bugs in current and older versions

Bugs that are listed in an older version section are supposedly fixed in later versions. Bugs listed in the topmost section may also exist in older versions.

recoll 1.17.0

• The chm filter handles badly some CHM files with encoded internal URLs (the whole file or some parts are not indexed). There is an updated filter on the filters section of the download page.
• The application style sheet is not reapplied when changed from the preferences menu, you have to restart the GUI.
• It will sometimes happen that the result list paragraph format stored in the Qt preferences file will get garbled, causing result lists with no displayed paragraphs (the counts and pages are ok, the results can be seen in table mode, but not in list mode). The workaround is to go to

  Preferences->Query configuration->User interface

  and erase the result paragraph format string (^A DEL in the text area), this will reset the string to the default value.
• Real time indexer: when running with gamin on FreeBSD, the indexer can deadlock in the gamin dialog in some cases.
• After an upgrade, the recoll GUI sometimes crashes on startup. This is fixed by removing (back it up just in case) ~/.config/Recoll.org/recoll.conf, the QSettings storage for recoll.

recoll 1.16.2

recoll 1.16.1

• At least on OpenSUSE 12.1 / Qt 4.7.4 (and probably other environments), the links to Preview or Open inside the result list do not work. Also the GUI can crash if a temporary directory creation fails.
• The Python filters can crash under certain error conditions. This is a benign error, affecting just the current document, but it causes system reports.
• The query is run 2 times, in most cases. This does not cause a too dramatic performance impact because of caching but still...
• The output from some filters (most typically text files out from the zip filters) is sometimes not transcoded correctly to UTF-8, causing myriads of error messages (and a possible application crash due to another bug in the unac code, described further).
• There is a compilation issue on Linux systems with a 3.x kernel.
• Queries without search terms (ie: all files of a given mime type) fail with an "empty query" diagnostic.
• The recollq command line query program sometimes does not clean up its temporary directory.
• Indexing can crash on files with weird names (inconsistent with the locale) for which the format of the "file -i" command is unexpected. This is probably dependant on the type of system and/or locale. Workaround: arrange for the offending file not to be indexed (move it away or configure it out), or apply this patch, which should work with all versions from 1.13 to 1.16.1
• Under certain conditions, the indexer can use all available memory and crash. This is caused by a memory leak in an error handling path inside unac, and can only be triggered in specific conditions (all cases seen were from files inside zip archives). Workaround: arrange for the offending file not to be indexed (move it away or configure it out), or apply this patch, which should work with all versions from 1.13 to 1.16.1
• The lyx filter does not correctly detect the Lyx version, needed for correct indexing.
• A typo in a memory reallocation call inside the firefox web history indexing module may cause problems in a highly improbable case.
• Directory creations are not processed by the real time indexer (for indexing directory names).

recoll 1.16.0

• The recoll GUI program sometimes crashes when running a query while the indexing thread is active. Possible workarounds:
  
  • Upgrade to 1.16.1
  • Use the command line recollindex program to perform indexing (usually just type "recollindex" in a console, or see "man recollindex").
  • Do not run queries in recoll while the indexing thread is running (as indicated in the bottom status line).

recoll 1.15.7

• The default filter for files in Microsoft Word format (application/msword, .doc), antiword, has trouble with some relatively rare files with a very small text, resulting in the following error message:

  I'm afraid the text stream of this file is too small to handle.

  Only small files produced by Microsoft Word on a Mac, or by OpenOffice will trigger this message.
  Workaround: install wvWare and modify mimeconf to use the rcldoc filter (instead of directly executing antiword). Rcldoc will try antiword, then will use vwWare if it is available. This will result in slightly slower indexing for all normal .doc files. This fix was made the default in 1.16
• Compressed man pages could not be previewed.
• Sorting by document and file size in the result table does not work.
• idxflushmb was not handled while deleting documents in the index, leading to almost unbounded memory usage.
• Email messages for which there would be an error indexing an attachment would not be indexed at all.
• Performing a full index with release 1.11 or newer, over a version created with a much older recoll release may sometimes end with an error saying "backend doesn't implement metadata". If this happens, you need to delete the index directory (typically ~/.recoll/xapiandb/) and restart indexing. For big indexes, to avoid losing time, removing the directory preventively may be preferable .
• Text files bigger than 2 GB can not be indexed.
• Using the GUI preview while the indexing thread is running will sometimes crash the GUI or provoke other strangeness. This happens much more rarely than in 1.15.7, but still occurs. Workaround if this happens too frequently: use the standalone recollindex program instead of the GUI thread.
• Real time indexer: uncontrolled concurrent access to the global configuration can cause a startup crash (mostly of big file trees because of timing issues).
• Using the result preview while the indexing thread is running will sometimes crash the GUI or provoke other strangeness. This is apparently due to insufficient protection of resources shared by several threads. After recent cleanup, the problem occurs quite seldom but it is not completely gone. The current and unsatisfying workaround, is to avoid the situation, for example by using the standalone recollindex program instead of the GUI indexing thread.
• The GUI preview function sometimes fails with a non-sensical message about a non-related missing helper.
• Most operations on the parent document in the result table view are not connected and do nothing.
• The operations on the parent document in the result list right click menu (Preview and Open), do not work, they access the file's parent directory instead.
• The GUI option to remember sort state between invocations only works for sort by date.
• The rclzip filter can't handle utf-8 in path names for archive members. An updated filter is available.
• The rclzip and rclchm filters can't handle archive members with a colon (':') in the file name or path. The files are normally indexed and can be searched for, but they can't be displayed (neither opened nor previewed). There is a patch which fixes the issue (then needs full reindex for these files).
• The ignored suffixes list (recoll_noindex) is itself ignored in some cases.
• The man filter creates groff temporary png files in the home directory.
• Indexing can hang or crash after an error occurs on an archive member (which should have affected only the relevant document).
• The initial indexing pass in the real-time indexer does not monitor the X11 session which can create problems if the user ends the section at this point.
• Starting the indexing thread inside the GUI while another indexer (batch or real-time) is active will silently failed. It should show an error dialog.
• When an open error occurs on an external index while starting the GUI, the initial indexing dialog is started, which is incorrect because it cannot fix the problem.
• The result table row height is not adjusted according to default font size, and the vertical position of text in cells is often bad.

recoll 1.15.5

recoll 1.15.2

• If a result table column is both added and moved in the same GUI instance, the list becomes garbled (or/and the GUI crashes). Workaround: remove the Qt GUI config (.config/Recoll.org/recoll.conf), and perform the operation in 2 GUI sessions: add column, exit recoll, restart, move column.
• Clicking one of the category filter checkboxes (one of the media/message/text/... things) with an empty result list crashes the GUI (just like this, yeah, I know, quality insurance etc.). Workaround: don't click these before running the first query.
• Changing the indexing configuration parameters from the GUI while the indexing thread (not an external recollindex command) is running will sometimes (quite often) crash the GUI.
• Script files (ie: .sh .pl) indexed as text do not respect the maximum text file limit (a problem with, ie, shar archives identified as application/x-shellscript).
• indexing script for xml formats (ie: svg) sometimes stall for 30 S while xsltproc tries to access remote dtds.
• recollindex inapproprietely sets the nice value for its whole process group. In certain cases where the indexing monitor was launched at session start, this could set the whole session to low priority!

recoll 1.14.4

• rclmon.sh stop would not work.
• Some shell, awk, and perl scripts are not indexed. There is a simple configuration tweak workaround
• The tree walk in indexing could loop on symbolic links.
• If the user-chosen result list entry format results in several paragraphs (in the qt textedit sense), right clicks will only work inside the first one for each entry.

1.12.4

1.12.3

1.12.2

1.12.1

1.12.0

• To compile the Python interface for recoll 1.12, you need to edit setup.py and replace "rcldb/pathhash.cpp" with "utils/fileudi.cpp".
• rclman outputs control characters, causing problems with preview and phrase searches in manual pages.
• rcllyx has trouble with 8bit characters in file names.
• "recoll -q ..." processes incorrectly second and further command line arguments.
• The following problem was corrected by Xapian 1.0.11 or 1.0.12, and I can see no reason to use older versions and/or the patches below. However, they're kept around in case someone needs them.
  NEAR expansion errors: recoll performs stemming expansion inside NEAR clauses (except if prevented by a capitalized entry). Because of a Xapian bug (up to 1.0.12 (or 11?)), NEAR does not support multiple OR subclauses. This manifests itself by a 'not implemented' Xapian exception or an explicit error message. Workarounds:
  • Prevent expansion of NEAR terms (possibly except one) by capitalizing them.
  • Or apply the following patch to xapian, inside the "api/" directory:
    0.x versions: xapian/xapNearDistrib-0.x.patch
    1.0.[0-9]: xapian/xapNearDistrib-1.0.0_9.patch
    1.0.10: xapian/xapNearDistrib-1.0.10.patch
    or fetch the already patched source from the local xapian/ directory then recompile, and install.

1.11.4

• Possibly harmful bug in strerror_r usage (GNU case).
• Incorrect handling of "accents" inside Japanese katakana text.
• Using the "Erase history" command on an empty history would cause recoll to crash.

1.11.1

• Unicode space characters like 0x3000, Ideographic space where not detected inside user entries like the main interface search entry. Badly parsed searches would retrieve no results, when the same search entered with ascii space characters would have succeeded.
• Spaces were inserted inside CJK strings when building abstracts for the result list.
• Accent removal should not be performed for Japanese.
• When using the query language, an OR part with more than two terms will swallow preceding AND terms, one for each additional OR. Ex: (champagne ext:odt OR ext:sxw OR ext:lyx) will be interpreted as "champagne OR ext:odt OR ext:sxw OR ext:lyx" instead of the correct "champagne AND (ext:odt OR ext:sxw OR ext:lyx)" Workaround until the fix is issued: add non-existing terms before the OR part and check the resulting query: "champagne bogusxyztv ext:odt OR ext:sxw OR ext:lyx"
• The "Copy file name" and "Copy URL" entries of the right-click menus only copy the data to the X11 primary selection (use middle-button click to paste). This is probably a mistake, the data should be copied to the clipboard too (permitting the use of the "Paste" edit menu entry or Ctrl+V in the target).
• Possibly harmful bug in strerror_r usage (GNU case).

1.10.6

• If the locale is not utf-8, non-ascii command line arguments to recoll and recollq are not converted to utf-8, which may prevent, for example, the kde applet from working. The workaround is to apply the following one-line fix to qtgui/main.cpp, recompile and install recoll:

              386c386
              <        sSearch->setSearchString(QString::fromUtf8(qstring.c_str()));
              ---
              >        sSearch->setSearchString(QString::fromLocal8Bit(qstring.c_str()));
            

1.10.1

• A relatively simple error case can cause the indexer to stop processing an mbox file (forgetting all subsequent messages). More specifically, this happens when encountering more than than a few dozen errors while handling attachments. This is relatively common: for exemple if an external helper application is missing and multiple attachments of the affected type are found (ie: multiple images and no exiftool). Workaround: install the helper application.
• The decoding of base-64 data in emails fails in a relatively uncommon but sometimes encountered case.
• In a preview window, when walking the search term hits with the Previous/Next buttons, 'Previous' actually acts as 'Next' (it does work normally for the local search).
• Problems in detecting message separators inside Thunderbird mailboxes (quite probably mainly for messages imported from outlook?). Can lead to unindexed messages, and even apparently indexer crashes in some cases.
• File names indexed as terms can sometimes overflow the maximum term size, halting the indexing.
• For Phrase/Near searches, only the first term group is highlighted in preview.

1.10.0

• If a filter fails while trying to extract the data from a file, the file will not be indexed at all (not even the file name). The file name should be indexed in this case. This happens in particular in the very common case where the helper application is not installed (ie: missing Exiftool -> no *.jpg names in the index).
• If several query language "ext:" qualifiers are specified, they will be joined by an AND instead of OR, resulting in no results. Using an explicit OR doesn't work (actually OR + field names is generally broken). In some cases, you can use a "type:" qualifier as a workaround.

1.9.x

• Problems have been reported indexing big mailstores (several hundreds of thousands of messages): resulting in a very big database and even crashes.

1.8.2

• Under ubuntu (at least, maybe debian too), the default awk interpreter (mawk) is ancient, and the recoll pdf input filter does not work (removes all space characters). This can be solved by installing the gawk package. $ apt-get install gawk $ update-alternatives --set awk /usr/bin/gawk
• There are sometimes problems with document deletions: the index can get in a state where deleted or moved documents are not purged from the index (the log file says that the doc are deleted, but they aren't actually). When this happens, the only solution currently is to reindex from scratch (recollindex -z). This is due to a xapian bug, which is fixed in xapian 1.0.2, or you can apply the following patch to xapian 1.0.1 to fix it: http://www.lesbonscomptes.com/recoll/xapian/xapian-delete-document.patch
• The dates shown for email attachments in a result list are the email folder modification date. This should be inherited from the parent message instead.
• There are a few problems in the qt4 version of recoll:
• Some accelerators (esc-spc, ctl-arrow) do not work, neither do copy/paste between the result list and preview windows and x11 applications.
• The qt4 q3textedit::find() method is extremely slow, so that positionning to first search term in Recoll preview has been disabled, and the application will sometimes appear to be looping when using the find feature in the preview window (it's not looping, it's searching...)

1.8.1

• This is not really a bug but .beagle really should be included in "skippedNames", or you end up indexing the beagle text cache, which is not really desirable.
• Doc bug: the manual states that the query language supports a "mime:" switch to filter mime types. There is currently no such thing.

1.7.5

• Debian and Ubuntu: the rclsoff Openoffice filter doesn't work, because of an incorrect shell syntax (understood by bash but not sh). To fix, you edit /usr[/local]/share/recoll/filters/rclsoff and can change the line: trap cleanup EXIT SIGHUP SIGQUIT SIGINT SIGTERM into: trap cleanup EXIT HUP QUIT INT TERM or download the updated filter from the filters page: http://www.recoll.org/filters/filters.html

1.7.3

• Processing will stop on first error while indexing an mbox file. This could happen just because an attachment could not be decoded, and can cause non-indexing of many messages. The most probable cause of error is a missing filter (ie for ms-word files), so the temporary workaround would be to install the missing filters. This bug is specific to 1.7 and 1.6 users need not worry. A correction will be issued very soon.
• Messages of type multipart/signed are not indexed.

1.6.2

• Relatively unfrequent issue with message boundary detection in mbox files, could cause miscellaneous problems.
• Executing an external viewer for a file with single-quotes in the name would not work.

1.5.10

• If a defaultcharset was set in the configuration file for a subdirectory, it would stay in effect for all subsequent files/directories (except if explicitely overridden), potentially causing many transcoding errors.

1.5.[1-7]

• Dates in result list come from the file's ctimes, which may be confusing
• Some rare MIME messages with null boundaries can crash the indexer.

1.5.0

• Under some conditions, recoll startup and exit could be very slow: the simple search history list had serious problems with non-ascii strings, whose size sometimes doubled at each program startup/stop.

1.3.3

• Several of the external filters did not handle path names with embedded spaces (rcluncomp rclsoff rclps rclmedia rcldjvu). This is fixed in 1.4.
• If your QT installation is built with the QT_NO_STL flag, Recoll will not compile. I have a patch for this (will be fixed in the next release), contact me if you get the problem. Typical error message: main.cpp:160: error: no match for 'operator+=' in 'msg += reason'
• The 'None of these words' field in the complex search does not work if there are no other filled fields (it transforms into an ordinary search). Workaround: enter very common term(s) in the 'any of these words' field.
• Indexing cannot currently be conveniently and cleanly stopped when it's started. You can kill the process, and keyboard interrupt might work, but this may leave the database in a bad state. This is fixed in the upcoming release, there is no current workaround.

1.2.2

• The preview window is supposed to scroll after loading the document so that the first search term is visible. This does not work in many cases.
• The result list title is not shown for sorted lists Notes on older versions:
• Trouble compiling on some linux systems (Gentoo and Slackware?). There existed a quite common issue where the Recoll link will fail trying to use a libstdc++.la file. This was due to a problem with the xapian-config program. A workaround has been included in the configure script for recoll 1.2.2, and the problem should not occur any more.
• Case-insensitive search should now work in most cases (used to not work except for accented ascii).
• All directories and files with names beginning with a dot were ignored by the skippedNames directive in the default recoll.conf file from older versions (no indexing of mozilla or thunderbird email !). An upgrade will not fix this (it will not modify an existing configuration). You need to edit recoll.conf by hand and remove the .* from skippedNames.
