downstream link signal only within job

only add the private ANSI sequence to the output of laminarc start/run commands used for adding a hyperlink to the frontend if we are within a job execution (tested with __LAMINAR_SETENV_PIPE). this makes parsing the output easier, which is likely to be more common when laminarc is invoked externally

 ## Packaging for distributions

 The `pkg` directory contains shell scripts which use docker to build native packages (deb,rpm) for common Linux distributions. Note that these are very simple packages which may not completely conform to the distribution's packaging guidelines, however they may serve as a starting point for creating an official package, or may be useful if the official package lags.

-# Nodes and Tags
+# Contexts

-In Laminar, a *node* is an abstract concept allowing more fine-grained control over job execution scheduling. Each node can be defined to support an integer number of *executors*, which defines how many runs can be executed simultaneously.
+In Laminar, each run of a job is associated with a context. The context defines an integer number of *executors*, which is the amount of runs which the context will accept simultaneously. A context may also provide additional environment variables.

-A typical example would be to allow only a few concurrent CPU-intensive jobs (such as compilation), while simultaneously allowing many more less-intensive jobs (such as monitoring or remote jobs). To create a node named `build` with 3 executors, create the file `/var/lib/laminar/cfg/nodes/build.conf` with the following content:
+Uses for this feature include limiting the amount of concurrent CPU-intensive jobs (such as compilation); and controlling access to jobs [executed remotely](#Remote-jobs).

-```
-EXECUTORS=3
-```
+If no contexts are defined, Laminar will behave as if there is a single context named "default", with `6` executors. This is a reasonable default that allows simple setups to work without any consideration of contexts.

-To associate jobs with nodes, laminar uses *tags*. Tags may be applied to nodes and jobs. If a node has tags, only jobs with a matching tag will be executed on it. If a node has no tags, it will accept any job. To tag a node, add them to `/var/lib/laminar/cfg/nodes/NODENAME.conf`:
+## Defining a context

-```
-EXECUTORS=3
-TAGS=tag1,tag2
-```
-
-To add a tag to a job, add the following to `/var/lib/laminar/cfg/jobs/JOBNAME.conf`:
-
-```
-TAGS=tag2
-```
-
-If Laminar cannot find any node configuration, it will assume a single node with 6 executors and no tags.
-
-## Grouping jobs with tags
-
-Tags are also used to group jobs in the web UI. Each tag will presented as a tab in the "Jobs" page.
-
-## Node scripts
-
-If `/var/lib/laminar/cfg/nodes/NODENAME.before` exists, it will be executed before the run script of a job scheduled to that node. Similarly, if `/var/lib/laminar/cfg/nodes/NODENAME.after` exists, it will be executed after the run script of a job scheduled to that node.
-
-## Node environment
-
-If `/var/lib/laminar/cfg/nodes/NODENAME.env` exists and can be parsed as a list of `KEY=VALUE` pairs, these variables will be exposed as part of the run's environment.
-
-# Remote jobs
-
-Laminar provides no specific support, `bash`, `ssh` and possibly NFS are all you need. For example, consider two identical target devices on which test jobs can be run in parallel. You might create a [node](#Nodes-and-Tags) for each, `/var/lib/laminar/cfg/nodes/target{1,2}.conf` with a common tag:
+To create a context named "my-env" which only allows a single run at once, create `/var/lib/laminar/cfg/contexts/my-env.conf` with the content:

 ```

-In each node's `.env` file, set the individual device's IP address:
+## Associating a job with a context
+
+When trying to start a job, laminar will wait until the job can be matched to a context which has at least one free executor. You can define which contexts the job will associate with by setting, for example,
+
+```
+CONTEXTS=my-env-*,special_context
+```
+
+in `/var/lib/laminar/cfg/jobs/JOB.conf`. For each of the patterns in the comma-separated list `CONTEXTS`, Laminar will iterate over the known contexts and associate the run with the first context with free executors. Patterns are [glob expressions](http://man7.org/linux/man-pages/man7/glob.7.html).
+
+If `CONTEXTS` is empty or absent (or if `JOB.conf` doesn't exist), laminar will behave as if `CONTEXTS=default` were defined.
+
+## Adding environment to a context

+Append desired environment variables to `/var/lib/laminar/cfg/contexts/CONTEXT_NAME.conf`:

+```
+DUT_IP=192.168.3.2

+# Colours in log output
+
+Laminar's frontend supports ANSI colours using the [ansi-up library](https://github.com/drudru/ansi_up). Unfortunately, there is no standard way of convincing applications to output colours when not connected to a tty. It is recommended to set [CLICOLOR_FORCE=1](https://bixense.com/clicolors/) in Laminar's [global environment file](#Environment-variables), plus any of the following environment variables that may be relevant (please submit more):
+
+* git: `GIT_CONFIG_PARAMETERS='color.status=always' 'color.ui=always'`
+* google test: `GTEST_COLOR=1`
+* grep: `GREP_OPTIONS=--color=always`
+
+More intrusive options for other common tools which do not support enabling colours via environment variable:
+
+* gcc and clang: Add `-fdiagnostics-color=always` to compile flags

+## Setting the page title
+
+Change `LAMINAR_TITLE` in `/etc/laminar.conf` to your preferred page title. Laminar must be restarted for this change to take effect.

+## Custom HTML template
+
+If it exists, the file `/var/lib/laminar/custom/index.html` will be served by laminar instead of the default markup that is bundled into the Laminar binary. This file can be used to change any aspect of Laminar's WebUI, for example adding menu links or adding a custom stylesheet.

Author	SHA1	Message	Date
Oliver Giles	7f7e8d2455	downstream link signal only within job only add the private ANSI sequence to the output of laminarc start/run commands used for adding a hyperlink to the frontend if we are within a job execution (tested with __LAMINAR_SETENV_PIPE). this makes parsing the output easier, which is likely to be more common when laminarc is invoked externally	2020-07-03 18:11:29 +12:00
Oliver Giles	d6be7f5079	fix minor compile warnings	2020-07-03 17:31:44 +12:00
Oliver Giles	09a208ebeb	report version and usage messages add -h\|--help usage messages to laminarc and laminard add a mechanism to compile in a version number, and display the version in the help messages and in the frontend. resolves #119	2020-07-03 15:13:11 +12:00
Oliver Giles	ae560b9de4	webui refresh WebUI rewritten in a more modern style, bootstrap is dropped in favour of plain css/grid. Hand-crafted svgs replace utf-8 glyphs for a more uniform look and smoother animation. webmanifest added for better mobile behaviour. No doubt minor tweaks will follow... resolves #57	2020-06-27 10:45:47 +12:00
Oliver Giles	4554039703	readme: add a warning about "make install" overriding laminar.conf resolves #96	2020-06-27 10:26:28 +12:00
Oliver Giles	cd64be2cea	UserManual: add a note that env vars are not shell-expanded resolves #120	2020-06-27 10:20:37 +12:00
Oliver Giles	559a6480ee	send SIGKILL to unterminated child jobs If we haven't exited 2 seconds after SIGTERM, send SIGKILL. This allows aborting of runs with wayward descendent processes.	2020-06-20 16:05:14 +12:00
Oliver Giles	1bb545e3f9	cmake: more appropriate use of CMAKE_INSTALL_PREFIX CMAKE_INSTALL_PREFIX is supposed to be used to set an install prefix of e.g. /usr or /usr/local. Because we need to install files to /etc, we had been requiring CMAKE_INSTALL_PREFIX=/ and installing using relative paths. The best practice method is to install to /etc using absolute paths, and then allow CMAKE_INSTALL_PREFIX to set where the final binaries actually go. Now that it actually has some meaning, the systemd service is generated to incorporate that path. Those wishing to use "make install" to install laminar to a subdir should use "make DESTDIR=path/to/subdir install" and NOT modify CMAKE_INSTALL_PREFIX. Documentation and packaging scripts updated accordingly.	2020-06-20 15:59:35 +12:00
Oliver Giles	de948c149e	don't report latestNum of non-existent job navigating to a non-existent job in the frontend caused a mutating change to the buildNums map, and returing the latestNum field caused the frontend to repeatedly try to fetch the latest run, which could overload the backend	2020-06-20 15:46:18 +12:00
Oliver Giles	0f2e601692	use c++17, deprecate debian 9 (stretch) packaging C++17 has some nice new features, but Debian Stretch doesn't support a compiler which can use it. Stretch is oldstable for a while now anyway, so just deprecate support.	2020-06-20 15:39:34 +12:00
Oliver Giles	c690be3a90	set html lang="en" This fixes weird offers from browsers to translate erroneously detected languages	2020-06-19 12:13:09 +12:00
Oliver Giles	1cc6cc6ae9	unify SSE reconnect behaviour Chrome auto-reconnects when an EventSource connection is interrupted but Firefox doesn't. Enforce consistent behaviour by implementing reconnect logic.	2020-06-19 12:01:46 +12:00
Oliver Giles	d5cfa3b94e	connect stdin to /dev/null laminard is a daemon process and does not read from stdin. Usually we can rely on the process mananger to do this for us, but if not (e.g. laminard is run interactively), we need this so that child processes (job runs) will not be able to block on stdin. resolves #125	2020-06-15 12:31:42 +12:00
Oliver Giles	081becf23a	laminarc: correct variable lifetime of show-jobs etc the one-liner used to iterate on the results of the RPC calls for show-jobs, show-queued and show-running meant that the result collection was destroyed before we finished with it. Hoist it out of the loop. resolves #127	2020-06-14 07:49:02 +12:00
Oliver Giles	6c61fb3111	add missing #includes New compiler version exposed missing header files resolves #123	2020-05-22 11:42:16 +12:00
Oliver Giles	eadcdbdf9c	laminarc: improve exit codes and errors - return non-zero when failed to connect to laminard - only output trigger links on successful trigger - better error messages Resolves #121	2020-04-25 08:49:39 +12:00
Cameron Eagans	2e54773e83	Add the ability to customize index.html (#113 ) User may provide a custom index.html template file to be used instead of the built-in version. Changes to this file are watched by laminard using inotify in order to load and compress the custom file for gzip delivery, reusing the existing method for serving static assets. This feature obviates the custom css feature, so remove references from the manual and add a deprecation warning if it is used. Add a section to the UserManual describing how to use this feature and including a link to an example using Semantic UI.	2020-03-10 19:40:14 +02:00
Oliver Giles	f981491a34	define FNM_EXTMATCH to 0 if undefined FNM_EXTMATCH is undefined under musl. In that case, we just won't support extended match patterns. Resolves #110	2020-02-25 20:36:26 +02:00
Oliver Giles	a7e6094d01	replace KJ_ASSERT with LASSERT inadvertently reintroduced KJ_ASSERT with recent refactor. It uses __FILE__ which contains path to source, which is fixed with LASSERT	2020-01-02 08:16:55 +02:00
Oliver Giles	6f366e21cc	centos pkg fix: laminard in sbin minor packaging fix for laminard move made in `304ef797b`	2019-12-31 20:12:50 +02:00
Oliver Giles	2bf04d8157	allow setting a job description adding DESCRIPTION=foo to $JOBNAME.conf will display "foo" in the job overview page on the frontend Resolves #97	2019-12-25 14:37:16 +02:00
Oliver Giles	40b708c594	UserManual: remove outdated reference to tags	2019-12-25 14:34:17 +02:00
Oliver Giles	b8ab43b508	UserManual: add CLICOLOR_FORCE docs	2019-12-23 07:58:52 +02:00
Oliver Giles	3fde38c6b8	job leader process Implement a separate process, the "leader", which runs all the scripts for a job run, instead of directly from the main laminard process. This makes for a cleaner process tree view, where the owning job for a given script is clear; also the leader process acts as a subreaper to clean up any wayward descendent processes. Resolves #78.	2019-12-23 07:56:37 +02:00
Oliver Giles	304ef797b8	install laminard in usr/sbin not usr/bin complies with FHS	2019-12-13 11:39:30 +02:00
Oliver Giles	e6f338ceb2	readme: add sentence about contributing with link to the DCO. (hopefully) resolves #98	2019-12-13 11:17:31 +02:00
Oliver Giles	0384fc9a0a	Replace nodes/tags with contexts The nodes/tags system has not been particularly successful, it's not as intuitive as it could be, and in an attempt to be a single feature to address many use cases, ends up addressing none of them particularly well. This commit replaces nodes and tags with contexts. Each job may define which context(s) the job may be associated with. Laminar will only pop the job off the waiting queue when it can be assigned to a context. A context defines an integer number of executors, which represents how many runs can be simultaneously assigned to it. A context may provide extra environment variables. Essentially, a context replaces a node, and tags are gone. You just assign jobs to contexts directly, and you can use a glob expression. This should be more intuitive. For grouping jobs in the WebUI, a separate mechanism called "groups" is provided.	2019-12-13 10:42:22 +02:00
