* snapshot: support tar signature for compressed tarChristian Hesse2018-07-03-2/+10
| | | | | | | | | | | | This adds support for kernel.org style signatures where the uncompressed tar archive is signed and compressed later. The signature is valid for all tar* snapshots. We have a filter which snapshots may be generated and downloaded. This has to allow tar signatures now even if tar itself is not allowed. To simplify things we allow all signatures.

* cache: close race window when unlocking slotsJohn Keeping2018-06-27-23/+14
| | | | | | | | | | | | | | | | | | | | We use POSIX advisory record locks to control access to cache slots, but these have an unhelpful behaviour in that they are released when any file descriptor referencing the file is closed by this process. Mostly this is okay, since we know we won't be opening the lock file anywhere else, but there is one place that it does matter: when we restore stdout we dup2() over a file descriptor referring to the file, thus closing that descriptor. Since we restore stdout before unlocking the slot, this creates a window during which the slot content can be overwritten. The fix is reasonably straightforward: simply restore stdout after unlocking the slot, but the diff is a bit bigger because this requires us to move the temporary stdout FD into struct cache_slot.

* Makefile: drive asciidoc directly for HTML outputJohn Keeping2018-06-16-4/+8
| | | | | | | | | | | | | | This is mostly taken from Git's doc/Makefile, although simplified for our use. The output now uses Asciidoc's default CSS which I think looks a bit nicer than the Docbook formatting; as a result of this we no longer need our custom .css file. A side effect of this change is that temporary files generated from the HTML output no longer conflict with the manpage output format (because any temporary HTML output files use names derived from the output filename which includes .html).

* doc: use consistent id's when generating html filesTodd Zullinger2018-02-21-1/+1
| | | | | | | | | | | | | | | | | | | | | The html documentation is generated using a2x which calls docbook tools to do the work. The generate.consistent.ids parameter ensures that when the docbook stylesheet assigns an id value to an output element it is consistent as long as the document structure has not changed. Having consistent html files reduces frivolous changes between builds. Distributions can more easily deploy multiple architecture builds and compare changes between package versions. End-users avoid needless changes in files deployed or backed up. The generate.consistent.ids parameter was added in docbook-xsl-1.77.0. Older versions gracefully ignore the parameter, so we can pass the parameter unconditionally. Most distributions contain docbook-xsl newer than 1.77.0. This includes Fedora, Debian, Ubuntu, and RHEL/CentOS 7. RHEL/CentOS 6 and Debian Wheezy (old stable) ship with an older version, unsurprisingly. Signed-off-by: Todd Zullinger <tmz@pobox.com>
