Outdated egg!

This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for the CHICKEN 5 version of this egg, if it exists.

If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.

Introduction

Salmonella is a set of tools to test CHICKEN eggs. Here's a brief summary of features:

very light on dependencies (none at the moment)
parallelizable (salmonella-epidemy)
can be run with or without Internet access

Note: starting on version 2.0, salmonella is a rewrite of the salmonella 1.x series, which was available since CHICKEN 2.x. The documentation for the 1.x series is still available at http://wiki.call-cc.org/egg/salmonella-1.x.

Tools

This egg provides some command line tools. The next sections describe each of them.

salmonella

This is the core tool for testing eggs. salmonella can perform the following tests:

installation of eggs
dependencies verification
.meta file consistency check
egg tests execution
general egg consistency (i.e., can be used as an egg lint to avoid common mistakes when publishing a new egg or a new egg version)

salmonella generates a sexpr-based log file as output. That file can be used by tools like salmonella-html-report to generate a pretty output in HTML.

When executing, salmonella prints some basic information on the standard output. Detailed information can be viewed with the aforementioned salmonella-html-report or with salmonella-log-viewer, a tool which is provided by this egg. salmonella-log-viewer parses the log file generated by salmonella and formats the data on the standard output.

Command line options

Here's the output of salmonella -h with an explanation for each command line option:

 salmonella [ -h | --help ]
 salmonella --version
 salmonella [ [ <options> ] eggs ]
 
 When called without eggs in the command line, salmonella will try to
 find a .egg file in the current directory and process it (just like
 chicken-install).
 
 <options>:
 --log-file=<logfile>
     The name for the log file to be generated by salmonella
     (default=salmonella.log).
 
 --chicken-installation-prefix=<prefix dir>
     If you want to test eggs using a chicken installed on a certain directory,
     you can use this option (it should point to the same directory as given to
     `PREFIX' when installing CHICKEN). If omitted, salmonella uses CHICKEN
     tools from the current runtime's installation prefix.  Note that when this
     option is used, salmonella will look for "csi", "csc" and "chicken-install"
     under <prefix dir>/bin.  If the CHICKEN installed under <prefix dir>
     has different names for the CHICKEN tools (i.e., they were tweaked via
     CSI_PROGRAM, CSC_PROGRAM, CHICKEN_INSTALL_PROGRAM, PROGRAM_PREFIX or
     PROGRAM_SUFFIX at build time), you will need to use the --csi, --csc
     and/or --chicken-install parameters for salmonella.
 
 --chicken-install-args=<install args>
     This option can be used customize chicken-install's arguments.  You can
     use <repo> to indicate where you want the actual repository directory
     to be replaced by salmonella.
 
 --csi=<path to csi>
    Path to csi.  If provided, salmonella will use the csi pointed by
    this parameter instead of the one from the current runtime's
    installation prefix (or the static "csi" from the prefix set by
    --chicken-installation-prefix).
 
 --csc=<path to csc>
    Path to csc.  If provided, salmonella will use the csc pointed by
    this parameter instead of the one from the current runtime's
    installation prefix (or the static "csc" from the prefix set by
    --chicken-installation-prefix).
 
 --chicken-install=<path to chicken-install>
    Path to chicken-install.  If provided, salmonella will use the csi
    pointed by this parameter instead of the one from the current runtime's
    installation prefix (or the static "chicken-install" from the prefix set
    by --chicken-installation-prefix).
 
 --eggs-doc-dir=<doc dir>
     By default, salmonella checks if documentation for eggs exist by accessing
     the CHICKEN wiki.  If you have a local copy of the wiki documentation for
     eggs, you can use this option to point to the directory where they can be
     found.
 
 --keep-repo
     For each egg that salmonella tests, it sets the egg installation repository
     empty and removes it at the end of its execution.  This option makes
     salmonella keep the egg installation repository after testing each egg and
     after finishing its execution.  This option can save a lot of time when
     testing several eggs, at the cost of potentially making salmonella unable
     to catch dependencies problems.
 
 --skip-eggs=<comma-separated list of eggs to skip>
     A comma-separated list of eggs to be skipped.
 
 --repo-dir=<path to repo dir to be used>
     Alternative location for the egg installation directory used by salmonella.
     By default, salmonella generates a `salmonella-tmp-xxxxx' directory in the
     current directory.  This option can be useful when used with `--keep-repo'
     to reuse egg installation repositories for several salmonella executions.
 
 --clear-chicken-home
     Remove Scheme files from <chicken-installation-prefix>/share/chicken.
     WARNING: use this option with care.  If you don't understand the
     consequences of this option, DON'T USE IT.  Extra care when you don't
     use --chicken-installation-prefix -- in this case --clear-chicken-home
     will remove Scheme files from your "host" CHICKEN installation.
     This option is only effective when --keep-repo is NOT used.
 
 --verbosity=<number>
     A number to indicate salmonella's verbosity level.  0 means practically
     silent. 1 is mostly silent and 2 (default) prints some useful information
     while salmonella is running.

Some quick tips by example

Simplest case: testing eggs using the remote egg server and the chicken tools (chicken-install and csi) in the system PATH

 $ salmonella big-chicken slice

You can test all the available eggs using one of the following approaches:

1. If you have CHICKEN >= 4.7.2:

 $ salmonella `chicken-install -list`

2. If you don't have CHICKEN >= 4.7.2:

 $ salmonella `wget http://code.call-cc.org/cgi-bin/henrietta.cgi?list=1 -q -O -`

If you don't want to test some specific eggs, you can skip them:

 $ salmonella --skip-eggs=macosx,hfs+ `chicken-install -list`

You can tell salmonella to use a specific CHICKEN version:

 $ salmonella --chicken-installation-prefix=/usr/local/chicken-4.7.3 big-chicken slice

Not cleaning the egg installation repository after installing each egg may significantly speed up the salmonella execution time (the default behavior is to set the egg installation repository empty after testing each egg):

 $ salmonella --keep-repo big-chicken slice

warning: if you use --keep-repo, salmonella will not be able to catch dependencies problems.

If you want to reuse the same egg installation repository for multiple salmonella runs, you can provide a specific directory:

 $ salmonella --repo-dir=my-repo --keep-repo big-chicken slice

By default, salmonella generates a log file named salmonella.log in the current directory. You can change that by using the --log-file command line option:

 $ salmonella --log-file=my-log-file.log big-chicken slice

Using salmonella as an egg lint tool

Suppose you are working on a new egg and you want to check if it is working ok before releasing it (or a new version). You can use salmonella to check it:

 $ cd my-egg    # where your egg code is stored
 $ salmonella

salmonella-log-viewer

This tool can be used to turn salmonella log files into something readable on the standard output.

Just provide a salmonella log file as argument to salmonella-log-viewer:

   $ salmonella-log-viewer salmonella.log

Alternatively, you can use salmonella-html-report for a prettier and more complete format.

salmonella-epidemy

Note: this tool is currently not supported on Windows systems.

salmonella-epidemy can be used to run multiple salmonella instances in parallel. It can be handy when you have a multi-core machine and you want to make use of all cores, for example. The command line options are basically the same as for salmonella, plus a --instances=<number> to indicate how many salmonella instances you want to run in parallel.

This tool can significantly speed up salmonella execution times on multi-core machines.

Usage example:

 $ salmonella-epidemy --instances=2 big-chicken slice spiffy amb

salmonella-log-merger

This tool simply puts more than one salmonella log into a single one, so it can be used by tools like salmonella-log-viewer and salmonella-html-report.

Usage example:

 $ salmonella-log-merger --log-file=full.log file1.log file2.log

salmonella-log-inquirer

salmonella-log-inquirer can be used to query salmonella log files. Below you can see its help message and a usage example.

 salmonella-log-inquirer [ -h | -help | --help ]
   Print this message.
 
 salmonella-log-inquirer --version
   Show version and exit.
 
 salmonella-log-inquirer --log-info <log file>
   Show information about the environment where salmonella was executed
   to generate the given <log-file> (e.g., environment variables, C
   compiler, CHICKEN version, salmonella command line etc.)
 
 salmonella-log-inquirer --statistics <log file>
   Show simple statistics on installation, tests and documentation from
   the log file .
 
 salmonella-log-inquirer --list-eggs <log file>
   List eggs covered in <log file>.
 
 salmonella-log-inquirer --action=<action> --egg=<egg> [ --part=<part> ] <log file>
   Query <action> and, optionally, <part> for <egg> in <log file>.
 
 <action>s:
 fetch
 install
 check-version
 test
 meta-data
 
 <part>s (the default part is "message"):
 message
 status
 duration

Usage example:

 $ salmonella-log-inquirer --action=fetch --egg=this salmonella.log

Log file format

The command line tool writes a log file which contains records in the following format:

(<egg> <action> <status> <message> <duration>)

<egg>

Can be either a symbol that indicates the egg-name or #f to indicate the start and end actions (logged when salmonella is started and when it finishes testing, respectively).

<action>

A symbol to indicate the action that was executed. Can be one of the following values:

start: starting salmonella
fetch: fetching egg
install: installing egg
skip: skipping egg
test: testing egg
end: salmonella has finished

<status>

A numeric value indicating the exit status of the executed action. When the action is test and status is -1, it means that the egg has no tests.

<message>

The output generated by the commands executed to perform <action>. A string.

<duration>

The time (in seconds) that was taken to execute <action>.

For the start and end actions, the value is the seconds since epoch, so the total salmonella execution time can be determined by subtracting the start time from the end time.

Modules

Salmonella provides two modules:

salmonella: the core salmonella functionality and basic data strucuture for logs (report records)
salmonella-log-parser: provides procedures to access log files and compute simple statistics regarding log file data.

Environment variables

When running, salmonella sets the SALMONELLA_RUNNING environment variable. If you need to check if your tests code is being run by salmonella, this variable can be used.

Caveats

Testing executable files installed by eggs

Salmonella sets a private repository to install and test eggs, so when extensions install programs, they get installed into <salmonella-repo-dir>/bin, not into $CHICKEN_PREFIX/bin.

So, how to invoke (from tests/run.scm, for example) a binary executable file your egg installs? You have the following options:

you can build up the absolute pathname for the executable, like (make-pathname (program-path) "the-executable"). That is not going to work with salmonella, since the executable file will get installed into <salmonella-repo-dir>/bin, not $CHICKEN_PREFIX/bin. Since program-path points to $CHICKEN_PREFIX/bin (or, when $CHICKEN_PREFIX is not set, it falls back to C_INSTALL_BIN_HOME, which is set during CHICKEN's build time), salmonella won't find it, as salmonella didn't install it there. Salmonella may find it, in case you have that egg installed, but in this case you'll be testing a different program.
you can rely on the executable being found in your system's PATH variable. Salmonella actually prepends <salmonella-repo-dir>/bin to your system's PATH variable when running, so, if you call the executable file installed by your egg with with (system "the-executable"), for example, salmonella will run the right file. On the other hand, you if run chicken-install with the -test option, and the CHICKEN tools are not in the system's PATH (e.g. /some/dir/not/in/PATH/chicken-install -test), the executable installed by your egg will not be found.

So far the only "portable" solution is a combination of both options, which happens to be a bit ugly. Salmonella sets the SALMONELLA_RUNNING environment variable when it runs, so your test script may check that variable and assume your test executable will be found in PATH if it is set. If SALMONELLA_RUNNING is not set, just build up the absolute path to your executable using (program-path). Here's an example:

(use setup-api)

(define executable
  (make-pathname
   (if (get-environment-variable "SALMONELLA_RUNNING")
       #f ;; salmonella adds its REPO_PREFIX/bin to PATH
       (program-path))
   "executable-filename"))

salmonella-epidemy on Windows

salmonella-epidemy is currently not supported on Windows systems.

Version history

Version 3.2.0 (2024-12-17)

Support for CHICKEN 6
Set tmp-repo-share-dir to TMP_REPO/share instead of TMP_REPO/share/chicken

Version 3.1.1 (2023-12-29)

Fix version string

Version 3.1.0 (2023-12-29)

Show the value of CHICKEN_INSTALL_PREFIX in env-info
Make sure the end-time record actually represents the end of execution (thanks to Vasilij Schneidermann for reporting the issue)
Make a blank (test-dependencies) mean the same as a missing (test-dependencies) (thanks to Lassi Kortela).
Delete tmp-dir in case of premature exit.
Handle "non-standard" CHICKEN tool names. Add the following new command line parameters: --csi, --csc and --chicken-install (thanks to nikola2 on IRC for pointing out this issue).
Close stdin on non-windows shell for all commands.
Call chicken-install for CHICKEN 4 with -debug.
Remove --eggs-source-dir from help message. --eggs-source-dir has been removed in 76c6e5623ee.
The version of the C compiler used for tests is showed in env-info. When --version for the C compiler doesn't work, try -version (e.g., TCC).

Version 3.0.1 (2020-08-19)

Remove code that assumed a file listing import libs exists
Fix path to chicken import import libraries (thanks to zilti on IRC for reporting this issue)
Add useless-test-dependencies check (in case eggs specify test dependencies but have no tests, emit a warning)

Version 3.0.0

CHICKEN 5 support. Now both CHICKEN 4 and CHICKEN 5 are supported. Most of the code is shared. Where CHICKEN 4 and 5 are not compatible, cond-expand is used for version-specific implementations.
New command line tool: salmonella-log-inquirer. This tool can be used to query salmonella log files.
More strict command line parser. Now invalid command line options are detected and reported as errors.
Exit non-zero in case of errors. Salmonella now exits non-zero in case of any check failure.
Add --clear-chicken-home command line option for salmonella and salmonella-epidemy. Don't use this option unless you know exactly what you are doing. Check the documentation of this option before using it.
The --eggs-source-dir option has been removed. It is still possible to use salmonella with a local directory containing egg sources by configuring chicken-install (-t local -l <eggs-source-dir> in CHICKEN 4 and by configuring the location form in PREFIX/share/chicken/setup.defaults in CHICKEN 5).
Replace --salmonella-prefix command line option by --salmonella-tools-dir. salmonella-epidemy relies on both salmonella and salmonella-log-merger. Since portably determining the directory of salmonella-epidemy is not trivial, and we don't want to rely on $PATH to call external tools, --salmonella-tools-dir has been created. With this, --salmonella-prefix became useless.
Salmonella now copy csc and csi from <host-prefix>/bin to <tmp-dir>/bin. With that, salmonella no longer adds <host-prefix>/bin to $PATH, which would cause salmonella to overlook eggs that rely on executables installed in <host-prefix>/bin but not declared as dependencies.
Many bugs fixed

Version 2.7

Command line tools handle --version (suggested by Michael Stapelberg)
salmonella: prepend <repo dir>/bin and <chicken-installation-prefix>/bin to PATH
salmonella: fix scrutinizer warnings
salmonella: set CHICKEN_C_INCLUDE_PATH
salmonella: print/log environment variables set when running
salmonella-epidemy: delete repo-dir, unless --keep-repo is provided
salmonella-epidemy: write per-instance temporary directories in repo-dir
salmonella-epidemy: show when instances are finished
salmonella-epidemy: fix verbosity handling
salmonella-epidemy: properly escape special shell characters in --chicken-install-args
salmonella-epidemy: remove --eggs-source-dir support due to concurrency issues
salmonella-epidemy: unless --salmonella-prefix is provided, salmonella-epidemy calls salmonella from the same prefix
salmonella-epidemy: add -h|--help command line options
salmonella-epidemy: correctly handle --skip-eggs

Version 2.6

Handle broken .meta files
Handle version specification in test-depends (thanks to Peter Bex for pointing that out)
Fixed filenames for chicken and csi on mingw (.exe extension). Thanks to Dan Leslie for pointing that out.
The --this-egg command line option has been deprecated

Version 2.5

Log check-version actions even when fetching eggs from remote servers (i.e., no --eggs-source-dir), so version numbers can get logged

Version 2.4

"Fixed" hack to remove -test from chicken-install arguments when installing eggs

Version 2.3

Bug fix: reference to unbound variable eggs (thanks to Shawn Rutledge for noticing that)

Version 2.2

Only create the temporary repo dir when it is necessary (i.e., not for handling --help or when there's nothing to do)

Version 2.1

Hours, minutes and seconds formatted with exact numbers (prettify-time)

Version 2.0

Rewrite of the 1.x version
