6 opam admin-upgrade - Upgrades repository from earlier opam versions.
7
9 opam admin upgrade [OPTION]…
10
12 This command reads repositories from earlier opam versions, and
13 converts them to repositories suitable for the current opam version.
14 Packages might be created or renamed, and any compilers defined in the
15 old format ('compilers/' directory) will be turned into packages, using
16 a pre-defined hierarchy that assumes OCaml compilers.
17
19 --clear-cache
20 Instead of running the upgrade, clear the cache of archive hashes
21 (held in ~/.cache), that is used to avoid re-downloading files to
22 obtain their hashes at every run.
23 -m URL, --mirror=URL
25 Don't overwrite the current repository, but put an upgraded mirror
26 in place in a subdirectory, with proper redirections. Needs the URL
27 the repository will be served from to put in the redirects (older
28 versions of opam don't understand relative redirects).
29 --no
31 Answer no to all opam yes/no questions without prompting. See also
32 --confirm-level. This is equivalent to setting $OPAMNO to "true".
33 -y, --yes
35 Answer yes to all opam yes/no questions without prompting. See also
36 --confirm-level. This is equivalent to setting $OPAMYES to "true".
37
39 These options are common to all commands.
40 --best-effort
42 Don't fail if all requested packages can't be installed: try to
43 install as many as possible. Note that not all external solvers may
44 support this option (recent versions of aspcud or mccs should).
45 This is equivalent to setting $OPAMBESTEFFORT environment variable.
46 --cli=MAJOR.MINOR (absent=2.1)
48 Use the command-line interface syntax and semantics of MAJOR.MINOR.
49 Intended for any persistent use of opam (scripts, blog posts,
50 etc.), any version of opam in the same MAJOR series will behave as
51 for the specified MINOR release. The flag was not available in opam
52 2.0, so to select the 2.0 CLI, set the OPAMCLI environment variable
53 to 2.0 instead of using this parameter.
54 --color=WHEN
56 Colorize the output. WHEN must be one of always, never or auto.
57 --confirm-level=LEVEL
59 Confirmation level, LEVEL must be one of ask, no, yes or
60 unsafe-yes. Can be specified more than once. If --yes or --no are
61 also given, the value of the last --confirm-level is taken into
62 account. This is equivalent to setting $OPAMCONFIRMLEVEL`.
63 --criteria=CRITERIA
65 Specify user preferences for dependency solving for this run.
66 Overrides both $OPAMCRITERIA and $OPAMUPGRADECRITERIA. For details
67 on the supported language, and the external solvers available, see
68 http://opam.ocaml.org/doc/External_solvers.html. A general guide to
69 using solver preferences can be found at
70 http://www.dicosmo.org/Articles/usercriteria.pdf.
71 --cudf=FILENAME
73 Debug option: Save the CUDF requests sent to the solver to
74 FILENAME-<n>.cudf.
75 --debug
77 Print debug message to stderr. This is equivalent to setting
78 $OPAMDEBUG to "true".
79 --debug-level=LEVEL
81 Like --debug, but allows specifying the debug level (--debug sets
82 it to 1). Equivalent to setting $OPAMDEBUG to a positive integer.
83 --git-version
85 Print the git version of opam, if set (i.e. you are using a
86 development version), and exit.
87 --help[=FMT] (default=auto)
89 Show this help in format FMT. The value FMT must be one of auto,
90 pager, groff or plain. With auto, the format is pager or plain
91 whenever the TERM env var is dumb or undefined.
92 --ignore-pin-depends
94 Ignore extra pins required by packages that get pinned, either
95 manually through opam pin or through opam install DIR. This is
96 equivalent to setting IGNOREPINDEPENDS=true.
97 --json=FILENAME
99 Save the results of the opam run in a computer-readable file. If
100 the filename contains the character `%', it will be replaced by an
101 index that doesn't overwrite an existing file. Similar to setting
102 the $OPAMJSON variable.
103 --no-aspcud
105 Removed in 2.1.
106 --no-auto-upgrade
108 When configuring or updating a repository that is written for an
109 earlier opam version (1.2), opam internally converts it to the
110 current format. This disables this behaviour. Note that
111 repositories should define their format version in a 'repo' file at
112 their root, or they will be assumed to be in the older format. It
113 is, in any case, preferable to upgrade the repositories manually
114 using opam admin upgrade [--mirror URL] when possible.
115 -q, --quiet
117 Disables --verbose.
118 --root=ROOT
120 Use ROOT as the current root path. This is equivalent to setting
121 $OPAMROOT to ROOT.
122 --safe, --readonly
124 Make sure nothing will be automatically updated or rewritten.
125 Useful for calling from completion scripts, for example. Will fail
126 whenever such an operation is needed ; also avoids waiting for
127 locks, skips interactive questions and overrides the $OPAMDEBUG
128 variable. This is equivalent to set environment variable $OPAMSAFE.
129 --solver=CMD
131 Specify the CUDF solver to use for resolving package installation
132 problems. This is either a predefined solver (this version of opam
133 supports builtin-mccs+lp(), builtin-mccs+glpk,
134 builtin-dummy-z3-solver, builtin-dummy-0install-solver, aspcud,
135 mccs, aspcud-old, packup), or a custom command that should contain
136 the variables %{input}%, %{output}%, %{criteria}%, and optionally
137 %{timeout}%. This is equivalent to setting $OPAMEXTERNALSOLVER.
138 --strict
140 Fail whenever an error is found in a package definition or a
141 configuration file. The default is to continue silently if
142 possible.
143 --switch=SWITCH
145 Use SWITCH as the current compiler switch. This is equivalent to
146 setting $OPAMSWITCH to SWITCH.
147 --use-internal-solver
149 Disable any external solver, and use the built-in one (this
150 requires that opam has been compiled with a built-in solver). This
151 is equivalent to setting $OPAMNOASPCUD or $OPAMUSEINTERNALSOLVER.
152 -v, --verbose
154 Be more verbose. One -v shows all package commands, repeat to also
155 display commands called internally (e.g. tar, curl, patch etc.)
156 Repeating n times is equivalent to setting $OPAMVERBOSE to "n".
157 --version
159 Show version information.
160 -w, --working-dir
162 Whenever updating packages that are bound to a local,
163 version-controlled directory, update to the current working state
164 of their source instead of the last committed state, or the ref
165 they are pointing to. As source directory is copied as it is, if it
166 isn't clean it may result on a opam build failure.This only affects
167 packages explicitly listed on the command-line.It can also be set
168 with $OPAMWORKINGDIR.
169
171 Opam makes use of the environment variables listed here. Boolean
172 variables should be set to "0", "no", "false" or the empty string to
173 disable, "1", "yes" or "true" to enable.
174 OPAMALLPARENS surround all filters with parenthesis.
176 OPAMASSUMEDEPEXTS see option `--assume-depexts'.
178 OPAMAUTOREMOVE see remove option `--auto-remove'.
180 OPAMBESTEFFORT see option `--best-effort'.
182 OPAMBESTEFFORTPREFIXCRITERIA sets the string that must be prepended to
184 the criteria when the `--best-effort' option is set, and is expected to
185 maximise the `opam-query' property in the solution.
186 OPAMBUILDDOC Removed in 2.1.
188 OPAMBUILDTEST Removed in 2.1.
190 OPAMCLI see option `--cli'.
192 OPAMCOLOR when set to always or never, sets a default value for the
194 `--color' option.
195 OPAMCONFIRMLEVEL see option `--confirm-level`. OPAMCONFIRMLEVEL has
197 priority over OPAMYES and OPAMNO.
198 OPAMCRITERIA specifies user preferences for dependency solving. The
200 default value depends on the solver version, use `config report' to
201 know the current setting. See also option --criteria.
202 OPAMCUDFFILE save the cudf graph to file-actions-explicit.dot.
204 OPAMCUDFTRIM controls the filtering of unrelated packages during CUDF
206 preprocessing.
207 OPAMCURL can be used to select a given 'curl' program. See OPAMFETCH
209 for more options.
210 OPAMDEBUG see options `--debug' and `--debug-level'.
212 OPAMDEBUGSECTIONS if set, limits debug messages to the space-separated
214 list of sections. Sections can optionally have a specific debug level
215 (for example, CLIENT:2 or CLIENT CUDF:2), but otherwise use
216 `--debug-level'.
217 OPAMDIGDEPTH defines how aggressive the lookup for conflicts during
219 CUDF preprocessing is.
220 OPAMDOWNLOADJOBS sets the maximum number of simultaneous downloads.
222 OPAMDROPWORKINGDIR overrides packages previously updated with
224 --working-dir on update. Without this variable set, opam would keep
225 them unchanged unless explicitly named on the command-line.
226 OPAMDRYRUN see option `--dry-run'.
228 OPAMEDITOR sets the editor to use for opam file editing, overrides
230 $EDITOR and $VISUAL.
231 OPAMERRLOGLEN sets the number of log lines printed when a sub-process
233 fails. 0 to print all.
234 OPAMEXTERNALSOLVER see option `--solver'.
236 OPAMFAKE see option `--fake'.
238 OPAMFETCH specifies how to download files: either `wget', `curl' or a
240 custom command where variables %{url}%, %{out}%, %{retry}%,
241 %{compress}% and %{checksum}% will be replaced. Overrides the
242 'download-command' value from the main config file.
243 OPAMFIXUPCRITERIA same as OPAMUPGRADECRITERIA, but specific to fixup.
245 OPAMIGNORECONSTRAINTS see install option `--ignore-constraints-on'.
247 OPAMIGNOREPINDEPENDS see option `--ignore-pin-depends'.
249 OPAMINPLACEBUILD see option `--inplace-build'.
251 OPAMJOBS sets the maximum number of parallel workers to run.
253 OPAMJSON log json output to the given file (use character `%' to index
255 the files).
256 OPAMKEEPBUILDDIR see install option `--keep-build-dir'.
258 OPAMKEEPLOGS tells opam to not remove some temporary command logs and
260 some backups. This skips some finalisers and may also help to get more
261 reliable backtraces.
262 OPAMLOCKED combination of `--locked' and `--lock-suffix' options.
264 OPAMLOGS logdir sets log directory, default is a temporary directory in
266 /tmp
267 OPAMMAKECMD set the system make command to use.
269 OPAMMERGEOUT merge process outputs, stderr on stdout.
271 OPAMNO answer no to any question asked, see options `--no` and
273 `--confirm-level`. OPAMNO is ignored if either OPAMCONFIRMLEVEL or
274 OPAMYES is set.
275 OPAMNOAGGREGATE with `opam admin check', don't aggregate packages.
277 OPAMNOASPCUD Deprecated.
279 OPAMNOAUTOUPGRADE disables automatic internal upgrade of repositories
281 in an earlier format to the current one, on 'update' or 'init'.
282 OPAMNOCHECKSUMS enables option --no-checksums when available.
284 OPAMNODEPEXTS disables system dependencies handling, see option
286 `--no-depexts'.
287 OPAMNOENVNOTICE Internal.
289 OPAMNOSELFUPGRADE see option `--no-self-upgrade'
291 OPAMPINKINDAUTO sets whether version control systems should be detected
293 when pinning to a local path. Enabled by default since 1.3.0.
294 OPAMPRECISETRACKING fine grain tracking of directories.
296 OPAMPREPRO set this to false to disable CUDF preprocessing. Less
298 efficient, but might help debugging solver issue.
299 OPAMREQUIRECHECKSUMS Enables option `--require-checksums' when
301 available (e.g. for `opam install').
302 OPAMRETRIES sets the number of tries before failing downloads.
304 OPAMREUSEBUILDDIR see option `--reuse-build-dir'.
306 OPAMROOT see option `--root'. This is automatically set by `opam env
308 --root=DIR --set-root'.
309 OPAMROOTISOK don't complain when running as root.
311 OPAMSAFE see option `--safe'.
313 OPAMSHOW see option `--show'.
315 OPAMSKIPUPDATE see option `--skip-updates'.
317 OPAMSKIPVERSIONCHECKS bypasses some version checks. Unsafe, for
319 compatibility testing only.
320 OPAMSOLVERALLOWSUBOPTIMAL (default `true') allows some solvers to still
322 return a solution when they reach timeout; while the solution remains
323 assured to be consistent, there is no guarantee in this case that it
324 fits the expected optimisation criteria. If `true', opam willcontinue
325 with a warning, if `false' a timeout is an error. Currently only the
326 builtin-z3 backend handles this degraded case.
327 OPAMSOLVERTIMEOUT change the time allowance of the solver. Default is
329 60.0, set to 0 for unlimited. Note that all solvers may not support
330 this option.
331 OPAMSTATS display stats at the end of command.
333 OPAMSTATUSLINE display a dynamic status line showing what's currently
335 going on on the terminal. (one of one of always, never or auto)
336 OPAMSTRICT fail on inconsistencies (file reading, switch import, etc.).
338 OPAMSWITCH see option `--switch'. Automatically set by `opam env
340 --switch=SWITCH --set-switch'.
341 OPAMUNLOCKBASE see install option `--unlock-base'.
343 OPAMUPGRADECRITERIA specifies user preferences for dependency solving
345 when performing an upgrade. Overrides OPAMCRITERIA in upgrades if both
346 are set. See also option --criteria.
347 OPAMUSEINTERNALSOLVER see option `--use-internal-solver'.
349 OPAMUSEOPENSSL force openssl use for hash computing.
351 OPAMUTF8 use UTF8 characters in output (one of one of always, never or
353 auto). By default `auto', which is determined from the locale).
354 OPAMUTF8MSGS use extended UTF8 characters (camels) in opam messages.
356 Implies OPAMUTF8. This is set by default on OSX only.
357 OPAMVALIDATIONHOOK if set, uses the `%{hook%}' command to validate an
359 opam repository update.
360 OPAMVERBOSE see option `--verbose'.
362 OPAMVERSIONLAGPOWER do not use.
364 OPAMWITHDOC see install option `--with-doc'.
366 OPAMWITHTEST see install option `--with-test.
368 OPAMWORKINGDIR see option `--working-dir'.
370 OPAMYES see options `--yes' and `--confirm-level`. OPAMYES has has
372 priority over OPAMNO and is ignored if OPAMCONFIRMLEVEL is set.
373 OPAMVAR_var overrides the contents of the variable var when
375 substituting `%{var}%` strings in `opam` files.
376 OPAMVAR_package_var overrides the contents of the variable package:var
378 when substituting `%{package:var}%` strings in `opam` files.
379
381 All scripts and programmatic invocations of opam should use `--cli' in
382 order to ensure that they work seamlessly with future versions of the
383 opam client. Additionally, blog posts or other documentation can
384 benefit, as it prevents information from becoming stale.
385 Although opam only supports roots (~/.opam/) for the current version,
387 it does provide backwards compatibility for its command-line interface.
388 Since CLI version support was only added in opam 2.1, use OPAMCLI to
390 select 2.0 support (as opam 2.0 will just ignore it), and `--cli=2.1'
391 for 2.1 (or later) versions, since an environment variable controlling
392 the parsing of syntax is brittle. To this end, opam displays a warning
393 if OPAMCLI specifies a valid version other than 2.0, and also if
394 `--cli=2.0' is specified.
395 The command-line version is selected by using the `--cli' option or the
397 OPAMCLI environment variable. `--cli' may be specified morethan once,
398 where the last instance takes precedence. OPAMCLI is only inspected if
399 `--cli' is not given.
400
402 As an exception to the following, the `exec' command returns 127 if the
403 command was not found or couldn't be executed, and the command's exit
404 value otherwise.
405 0 Success, or true for boolean queries.
407 1 False. Returned when a boolean return value is expected, e.g. when
409 running with --check, or for queries like opam lint.
410 2 Bad command-line arguments, or command-line arguments pointing to
412 an invalid context (e.g. file not following the expected format).
413 5 Not found. You requested something (package, version, repository,
415 etc.) that couldn't be found.
416 10 Aborted. The operation required confirmation, which wasn't given.
418 15 Could not acquire the locks required for the operation.
420 20 There is no solution to the user request. This can be caused by
422 asking to install two incompatible packages, for example.
423 30 Error in package definition, or other metadata files. Using
425 --strict raises this error more often.
426 31 Package script error. Some package operations were unsuccessful.
428 This may be an error in the packages or an incompatibility with
429 your system. This can be a partial error.
430 40 Sync error. Could not fetch some remotes from the network. This can
432 be a partial error.
433 50 Configuration error. Opam or system configuration doesn't allow
435 operation, and needs fixing.
436 60 Solver failure. The solver failed to return a sound answer. It can
438 be due to a broken external solver, or an error in solver
439 configuration.
440 99 Internal error. Something went wrong, likely due to a bug in opam
442 itself.
443 130 User interrupt. SIGINT was received, generally due to the user
445 pressing Ctrl-C.
