+Uwe has suggested we implement automatic detection of changes in class files.

+ If it reports a change, we can check if our template and layout file are

+Expectations of LyX developers
+\end_layout
+
+\begin_layout Standard
+Because the export tests are integration tests and take a long time to run,
+ LyX developers are rarely expected to run all of the tests.
+ Here are some good practices to follow by developers:
+\end_layout
+
+\begin_layout Itemize
+When making a non-trivial change to a .layout file, run the export and layout
+ tests corresponding with that .layout file.
+\end_layout
+
+\begin_layout Itemize
+When making non-trivial changes to a .lyx file, run the export tests correspondin
+g to that .lyx file.
+
+\begin_inset Foot

+\begin_layout Plain Layout
+This rule is due to revision.
+
+\end_layout

+\begin_layout Plain Layout
+There is an objection from the documentation maintainer that working on
+ the documentation must not be complicated by having to consider non-standard
+ exports.
+\end_layout
+
+\begin_layout Itemize
+successful compiling/testing an edited documentation file with pdflatex
+ suffices to ensure it can be commited, not tests with other exports are
+ required.
+\end_layout
+
+\begin_layout Plain Layout
+If sudden failures with other exports due to “half-tested” documentation
+ updates are a problem for the test maintainer, the test suite should use
+ copies that are
+\end_layout
+
+\begin_layout Itemize
+copied to a cache dir (autotests/samples/doc/, say) but not changed,
+\end_layout
+
+\begin_layout Itemize
+updated regularely (but on a time chosen by the test suite maintainer) from
+ the originals in lib/doc/
+\end_layout
+
+\begin_layout Plain Layout
+This way,
+\end_layout
+
+\begin_layout Itemize
+no test will fail due to ongoing work on documentation,
+\end_layout
+
+\begin_layout Itemize
+the documentation is still tested in full (with some delay),
+\end_layout
+
+\begin_layout Itemize
+failures with non-default export can be examined and handled accordingly
+ in one run with the cache update,

+A good question is why do we enable the tests for non-default formats? The
+ answer is that if a non-default route is broken it is often because a bug
+ was introduced in LyX and not because a document-specific change was made
+ that is not supported by the route.
+ In other words, there is a high signal/noise ratio in the export tests
+ for some non-default formats.

+\begin_layout Subsubsection
+check_load tests
+\end_layout
+
+\begin_layout Standard
+These tests check whether a .lyx file loads without any terminal messages.
+ They correspond to the manual operations of simply opening a .lyx file on
+ the terminal, exiting LyX once the file is loaded, and then checking whether
+ there is any output from the terminal.
+ These tests are useful for catching malformed .lyx files and parsing bugs.
+ They can also be used to find a .lyx file in which an instance of something
+ happens.
+ To do this, compile LyX with a local patch that outputs something to the
+ terminal when an instance is found, and then run the check_load tests to
+ see if any fail, which would mean that the situation occurs in the LyX
+ documentation files corresponding to the failed tests.
+ These tests are expectedly fragile: any LyX diagnostic message, which is
+ not necessarily an error, would cause the tests to fail.
+ Similarly, any message output by a library (e.g.
+ Qt) would also cause failure.
+ There are some messages that the check_load tests are instructed to ignore,
+ which are stored in the file

+\begin_layout Paragraph
+Running URL tests
+\end_layout
+
+\begin_layout Standard
+cmake is required to run the \SpecialChar LyX
+ tests, running them is not implemented for
+ autotools.
+\end_layout
+
+\begin_layout Standard
+The appropriate commands are:
+\end_layout
+
+\begin_layout Itemize
+
+\family typewriter
+ctest -L url
+\family default
+
+\begin_inset Newline newline
+\end_inset
+
+runs all tests with label

+\family default
+
+\begin_inset Newline newline
+\end_inset
+
+runs the tests 'check_accessible_urls'
+\end_layout

+\begin_layout Standard
+Associated test results can be examined in ctest-log directory in files
+ of the form 'LastFailed.*URLS.log'

+\end_layout
+
+\begin_layout Subsection
+When to set a fixed milestone?
+\end_layout
+
+\begin_layout Standard
+Only set a fixed milestone (like 2.1.4 or 2.2.0) if at least one of the following
+ holds:
+\end_layout
+
+\begin_layout Enumerate
+Somebody is actively working on a fix.
+\end_layout
+
+\begin_layout Enumerate
+The bug is so severe that it would block the release if it is not fixed.
+\end_layout
+
+\begin_layout Standard
+If a bug is important, but nobody is working on it, and it is no showstopper,
+ use a milestone like 2.1.x or 2.2.x.
+ For all other bugs, do not set a milestone at all.
+\end_layout
+
+\begin_layout Subsection
+Can we add rc entries in stable branch?
+\end_layout
+
+\begin_layout Standard
+No.
+ We are supposed to increase the prefs2prefs version number with such things.

+Rules
+\end_layout

+\begin_layout Standard
+There are 6
+\begin_inset space ~
+\end_inset
+
+rules in editing the docs:
+\end_layout
+
+\begin_layout Enumerate
+\begin_inset CommandInset label
+LatexCommand label
+name "enu:If-you-are"
+
+\end_inset
+
+If you are not the maintainer of a doc file or a chapter/section, you MUST
+ use change tracking so that the maintainer could review your changes
+\end_layout
+
+\begin_layout Enumerate
+Respect the formatting of the document.
+ The different files use different formatting styles.
+ That is OK and has historic reasons nobody fully knows ;-).
+ But it is important to be consistent within one file.
+\end_layout
+
+\begin_layout Enumerate
+All changes you make to a file in one language MUST also go the file in
+ the other actively maintained languages.
+ Normally the maintainer does this for you, if you are the maintainer, you
+ must do this by copying or changing the changed or added text to the other
+ files so that the translators sees the blue underlined text and know what
+ they have to translate and what was changed.
+\end_layout
+
+\begin_layout Enumerate
+You MUST assure that the document is compilable as
+\begin_inset Quotes eld
+\end_inset
+
+PDF (pdflatex)
+\begin_inset Quotes erd
+\end_inset
+
+ or the document's default output format after your changes.
+\end_layout
+
+\begin_layout Enumerate
+All fixes (typos, compilation fixes, updates info etc.) go at first into
+ the current GIT branch because the user should benefit from all fixes with
+ every minor release.
+ Feel free to commit directly to branch as long as you follow rule
+\begin_inset space ~
+\end_inset
+
+
+\begin_inset CommandInset ref
+LatexCommand ref
+reference "enu:If-you-are"

+ You can immediately commit to master as well.
+\end_layout
+
+\begin_layout Enumerate
+\begin_inset CommandInset label
+LatexCommand label
+name "enu:The-fileformat-of"
+
+\end_inset
+
+The fileformat of a file must not be changed unless you document a new feature
+ in LyX that requires a new fileformat.
+ The reason for this rule is to keep it easy for the doc maintainers to
+ port/backport changes to from master/branch.
+\end_layout
+
+\begin_layout Standard
+The main documentation consists of these files:
+\end_layout
+
+\begin_layout Description
+splash.lyx it is the first file you see after an installation.
+ We assume that a new user sees this.
+ It is therefore designed to be as simple as possible.
+ Therefore please don't add any new formatting, only fix typos etc.
+ Splash.lyx is up to date for \SpecialChar LyX
+ 2.1.x, currently maintained by Uwe Stöhr.
+\end_layout
+
+\begin_layout Description
+Intro.lyx This is the manual new users will read to learn \SpecialChar LyX
+.
+ It therefore uses a limited set of formatting.
+ For example a standard document class.
+ Since new users will first learn about the formatting possibilities of
+ \SpecialChar LyX
+ please keep this file that simple.
+ Intro.lyx is up to date for \SpecialChar LyX
+ 2.1.x, currently maintained by Uwe Stöhr.
+\end_layout
+
+\begin_layout Description
+Tutorial.lyx our tutorial.
+ It must be always up to date.
+ Normally there is nothing to add since we don't want to overwhelm new users
+ with too much details.
+ The will learn these details while using \SpecialChar LyX
+ and we have special manuals.
+ Tutorial.lyx is up to date for \SpecialChar LyX
+ 2.1.x, currently maintained by Uwe Stöhr.
+\end_layout
+
+\begin_layout Description
+UserGuide.lyx our main user guide.
+ It covers a mixture of basic and detailed information.
+ Some information is also in the Math and EmbeddedObjects manual so that
+ the UserGuide refers to these files.
+ UserGuide.lyx is up to date for \SpecialChar LyX
+ 2.1.x, currently maintained by Uwe Stöhr.
+\end_layout
+
+\begin_layout Description
+EmbeddedObjects.lyx a special manual to explain things like tables floats
+ boxes etc.
+ in all detail.
+ EmbeddedObjects.lyx is up to date for \SpecialChar LyX
+ 2.1.x, currently maintained by Uwe
+ Stöhr.
+\end_layout
+
+\begin_layout Description
+Math.lyx a special manual to explain everything regarding math in all detail.
+ Math.lyx is up to date for \SpecialChar LyX
+ 2.1.x, currently maintained by Uwe Stöhr.
+\end_layout
+
+\begin_layout Description
+Additional.lyx this manual covers information that would be too much detail
+ for the UserGuide or would make the UserGuide uncompilable or only compilable
+ when installing a lot of special \SpecialChar LaTeX
+-packages.
+ What should be in the UserGuide or better in Additional is a matter of
+ taste.
+ it is up to you to decide that.
+ Additional.lyx is not completely up to date for \SpecialChar LyX
+ 2.1.x.
+ Only chapter
+\begin_inset space ~
+\end_inset
+
+8 is up to date and currently maintained by Uwe Stöhr.
+ It certainly needs a rewrite and update.
+ For example many info in chapter
+\begin_inset space ~
+\end_inset
+
+2 and 3 are already covered by the UserGuide and/or the EmbeddedObjects
+ manual.
+\end_layout
+
+\begin_layout Description
+Customization.lyx this manual covers information how to customize \SpecialChar LyX
+ for certain
+ output formats, operating systems, languages etc.
+ It is currently completely out of date and needs a major rewrite and update.
+ If you do this please assure that your information are given for all OSes
+ and \SpecialChar LaTeX
+ distributions (meaning be as objective as possible).
