2015-03-13Enhance nscd's inotify support (Bug 14906).Carlos O'Donell
In bug 14906 the user complains that the inotify support in nscd is not sufficient when it comes to detecting changes in the configurationfiles that should be watched for the various databases. The current nscd implementation uses inotify to watch for changes in the configuration files, but adds watches only for IN_DELETE_SELF and IN_MODIFY. These watches are insufficient to cover even the most basic uses by a system administrator. For example using emacs or vim to edit a configuration file should trigger a reload but it might not if the editors use move to atomically update the file. This atomic update changes the inode and thus removes the notification on the file (as inotify is based on inodes). Thus the inotify support in nscd for configuration files is insufficient to account for the average use cases of system administrators and users. The inotify support is significantly enhanced and described here: https://www.sourceware.org/ml/libc-alpha/2015-02/msg00504.html Tested on x86_64 with and without inotify support.

2014-03-03nscd: Improved support for tracking startup failure in nscd service (BZ #16639)Siddhesh Poyarekar
Currently, the nscd parent process parses commandline options and configuration, forks on startup and immediately exits with a success. If the child process encounters some error after this, it goes undetected and any services started up after it may have to repeatedly check to make sure that the nscd service did actually start up and is serving requests. To make this process more reliable, I have added a pipe between the parent and child process, through which the child process sends a notification to the parent informing it of its status. The parent waits for this status and once it receives it, exits with the corresponding exit code. So if the child service sends a success status (0), the parent exits with a success status. Similarly for error conditions, the child sends the non-zero status code, which the parent passes on as the exit code. This, along with setting the nscd service type to forking in its systemd configuration file, allows systemd to be certain that the nscd service is ready and is accepting connections.

2011-10-07Implement caching of nscdUlrich Drepper
2011-07-11Generalize framework to register monitoring of files in nscdUlrich Drepper
nscd can clear caches when certain files change. The list of files was hardcoded so far and worked for nss_files and nss_dns and those modules which need no monitoring. nss_db, for instance, has its own set of files to monitor. Now the NSS modules themselves can request that certain files are monitored.
