Modelled after the i386 zfsloader. However, with no 2nd stage zfsboot to search for a bootable dataset, attempt a ZFS boot if there is more than one ZFS dataset found during the disk probe. sys/boot/userboot/zfs - build the ZFS boot library sys/boot/userboot/userboot/ conf.c - Add the ZFS pool and filesystem tables devicename.c - correctly format ZFS devices main.c - increase the size of the libstand malloc pool to account for the increased usage from ZFS buffers - probe for a ZFS dataset, and if one is found, attempt to boot from it. usr.sbin/bhyveload/bhyveload.c - allow multiple invocations of the '-d' option to specify multiple disks e.g. a raidz set. Up to 32 disks are supported. Tested with various combinations of GPT, MBR, single and multiple disks, RAID-Z, mirrors.

To enable virtual machine migration among a heterogeneous collection of physical machines, the hypervisor may have been configured to report an older processor family with a reduced feature set. Effectively, the reported processor family and its features are like a "least common denominator" for the collection of machines. Therefore, when the kernel is running in a virtual machine, instead of relying upon the processor family, we now test for features that prove that the underlying processor is not affected by the erratum. (The features that we test for are unlikely to ever be emulated in software on an affected physical processor.)

One specific problem this solves is when u-boot sets an fdtaddr variable to point to some memory address, then doesn't actually load a blob at that address. Now the header check will fail, and the code will move on to the fallback dtb compiled into the kernel (if any). --- sys/boot/fdt/fdt_loader_cmd.c | 63 +++++++++++++++++++++++++---------- 1 file changed, 45 insertions(+), 18 deletions(-) diff --git a/sys/boot/fdt/fdt_loader_cmd.c b/sys/boot/fdt/fdt_loader_cmd.c index d8ad9426bd72..b553a85f8572 100644 --- a/sys/boot/fdt/fdt_loader_cmd.c +++ b/sys/boot/fdt/fdt_loader_cmd.c @@ -128,6 +128,8 @@ fdt_find_static_dtb() char *strp; int i, sym_count; + debugf("fdt_find_static_dtb()\n"); + sym_count = symtab = strtab = 0; strp = NULL; @@ -189,6 +191,8 @@ fdt_load_dtb(vm_offset_t va) struct fdt_header header; int err; + debugf("fdt_load_dtb(0x%08jx)\n", (uintmax_t)va); + COPYOUT(va, &header, sizeof(header)); err = fdt_check_header(&header); if (err < 0) { @@ -229,6 +233,8 @@ fdt_load_dtb_addr(struct fdt_header *header) { int err; + debugf("fdt_load_dtb_addr(0x%p)\n", header); + fdtp_size = fdt_totalsize(header); err = fdt_check_header(header); if (err < 0) { @@ -252,39 +258,58 @@ fdt_setup_fdtp() { struct preloaded_file *bfp; struct fdt_header *hdr; + int err; const char *s; char *p; vm_offset_t va; + debugf("fdt_setup_fdtp()\n"); + + /* If we already loaded a file, use it. */ if ((bfp = file_findfile(NULL, "dtb")) != NULL) { - printf("Using DTB from loaded file.\n"); - return fdt_load_dtb(bfp->f_addr); - } - - if (fdt_to_load != NULL) { - printf("Using DTB from memory address 0x%08X.\n", - (unsigned int)fdt_to_load); - return fdt_load_dtb_addr(fdt_to_load); + if (fdt_load_dtb(bfp->f_addr) == 0) { + printf("Using DTB from loaded file.\n"); + return (0); + } } - /* Board vendors use both fdtaddr and fdt_addr names.

The ext4 developers tend to tag Ext4-specific flags as "incompatible" even when such features are not relevant for read-only support. This is a consequence of the process though which this filesystem is implemented without design and the fact that some new features are not extensible to ext2/3. Organize the features according to what we support and sort them so that we can now read-only mount filesystems with some features that may be found in newly formatted ext4 fs.

This will supercede all the existing WANDBOARD* configs, but those will be left around for a while to help people transition their customized configs to include this new one instead. --- sys/arm/conf/IMX6 | 155 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 155 insertions(+) create mode 100644 sys/arm/conf/IMX6 diff --git a/sys/arm/conf/IMX6 b/sys/arm/conf/IMX6 new file mode 100644 index 000000000000..7883f3e286da --- /dev/null +++ b/sys/arm/conf/IMX6 @@ -0,0 +1,155 @@ +# Kernel configuration for Wandboard +# +# For more information on this file, please read the config(5) manual page, +# and/or the handbook section on Kernel Configuration Files: +# +# http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-config.html +# +# The handbook is also available locally in /usr/share/doc/handbook +# if you've installed the doc distribution, otherwise always see the +# FreeBSD World Wide Web server (http://www.FreeBSD.org/) for the +# latest information. +# +# An exhaustive list of options and more detailed explanations of the +# device lines is also present in the ../../conf/NOTES and NOTES files. +# If you are in doubt as to the purpose or necessity of a line, check first +# in NOTES. +# +# $FreeBSD$ + +include "../freescale/imx/std.imx6" + +options HZ=250 # Scheduling quantum is 4 milliseconds. +options SCHED_4BSD # 4BSD scheduler +options PREEMPTION # Enable kernel thread preemption +options INET # InterNETworking +options INET6 # IPv6 communications protocols +#options SCTP # Stream Control Transmission Protocol +options FFS # Berkeley Fast Filesystem +options SOFTUPDATES # Enable FFS soft updates support +options UFS_ACL # Support for access control lists +options UFS_DIRHASH # Improve performance on big directories +options UFS_GJOURNAL # Enable gjournal-based UFS journaling +#options MD_ROOT # MD is a potential root device +options NFSCL # New Network Filesystem Client +#options NFSD # New Network Filesystem Server +options NFSLOCKD # Network Lock Manager +options NFS_ROOT # NFS usable as /, requires NFSCL +options MSDOSFS # MSDOS Filesystem +options CD9660 # ISO 9660 Filesystem +#options PROCFS # Process filesystem (requires PSEUDOFS) +options PSEUDOFS # Pseudo-filesystem framework +options TMPFS # TMP Memory Filesystem +options GEOM_PART_GPT # GUID Partition Tables. +options GEOM_LABEL # Provides labelization +options KTRACE # ktrace(1) support +options SYSVSHM # SYSV-style shared memory +options SYSVMSG # SYSV-style message queues +options SYSVSEM # SYSV-style semaphores +options _KPOSIX_PRIORITY_SCHEDULING # POSIX P1003_1B real-time extensions +options INCLUDE_CONFIG_FILE # Include this file in kernel + +# Debugging support.

principles of the configuration +language called `UCL` - universal configuration language. + +If you are looking for the libucl API documentation you can find it at [this page](doc/api.md). + +## Basic structure + +UCL is heavily infused by `nginx` configuration as the example of a convenient configuration +system. However, UCL is fully compatible with `JSON` format and is able to parse json files. +For example, you can write the same configuration in the following ways: + +* in nginx like: + +```nginx +param = value; +section { + param = value; + param1 = value1; + flag = true; + number = 10k; + time = 0.2s; + string = "something"; + subsection { + host = { + host = "hostname"; + port = 900; + } + host = { + host = "hostname"; + port = 901; + } + } +} +``` + +* or in JSON: + +```json +{ + "param": "value", + "param1": "value1", + "flag": true, + "subsection": { + "host": [ + { + "host": "hostname", + "port": 900 + }, + { + "host": "hostname", + "port": 901 + } + ] + } +} +``` + +## Improvements to the json notation. + +There are various things that make ucl configuration more convenient for editing than strict json: + +### General syntax sugar + +* Braces are not necessary to enclose a top object: it is automatically treated as an object: + +```json +"key": "value" +``` +is equal to: +```json +{"key": "value"} +``` + +* There is no requirement of quotes for strings and keys, moreover, `:` may be replaced `=` or even be skipped for objects: + +```nginx +key = value; +section { + key = value; +} +``` +is equal to: +```json +{ + "key": "value", + "section": { + "key": "value" + } +} +``` + +* No commas mess: you can safely place a comma or semicolon for the last element in an array or an object: + +```json +{ + "key1": "value", + "key2": "value", +} +``` +### Automatic arrays creation + +* Non-unique keys in an object are allowed and are automatically converted to the arrays internally: + +```json +{ + "key": "value1", + "key": "value2" +} +``` +is converted to: +```json +{ + "key": ["value1", "value2"] +} +``` + +### Named keys hierarchy + +UCL accepts named keys and organize them into objects hierarchy internally. Here is an example of this process: +```nginx +section "blah" { + key = value; +} +section foo { + key = value; +} +``` + +is converted to the following object: + +```nginx +section { + blah { + key = value; + } + foo { + key = value; + } +} +``` + +Plain definitions may be more complex and contain more than a single level of nested objects: + +```nginx +section "blah" "foo" { + key = value; +} +``` + +is presented as: + +```nginx +section { + blah { + foo { + key = value; + } + } +} +``` + +### Convenient numbers and booleans + +* Numbers can have suffixes to specify standard multipliers: + + `[kKmMgG]` - standard 10 base multipliers (so `1k` is translated to 1000) + + `[kKmMgG]b` - 2 power multipliers (so `1kb` is translated to 1024) + + `[s|min|d|w|y]` - time multipliers, all time values are translated to float number of seconds, for example `10min` is translated to 600.0 and `10ms` is translated to 0.01 +* Hexadecimal integers can be used by `0x` prefix, for example `key = 0xff`. However, floating point values can use decimal base only. +* Booleans can be specified as `true` or `yes` or `on` and `false` or `no` or `off`. +* It is still possible to treat numbers and booleans as strings by enclosing them in double quotes. + +## General improvements + +### Commments + +UCL supports different style of comments: + +* single line: `#` +* multiline: `/* ... */` + +Multiline comments may be nested: +```c +# Sample single line comment +/* + some comment + /* nested comment */ + end of comment +*/ +``` + +### Macros support + +UCL supports external macros both multiline and single line ones: +```nginx +.macro "sometext"; +.macro { + Some long text + .... +}; +``` +There are two internal macros provided by UCL: + +* `include` - read a file `/path/to/file` or an url `http://example.com/file` and include it to the current place of +UCL configuration; +* `try\_include` - try to read a file or url and include it but do not create a fatal error if a file or url is not accessible; +* `includes` - read a file or an url like the previous macro, but fetch and check the signature file (which is obtained +by `.sig` suffix appending). + +Public keys which are used for the last command are specified by the concrete UCL user. + +### Variables support + +UCL supports variables in input. Variables are registered by a user of the UCL parser and can be presented in the following forms: + +* `${VARIABLE}` +* `$VARIABLE` + +UCL currently does not support nested variables. To escape variables one could use double dollar signs: + +* `$${VARIABLE}` is converted to `${VARIABLE}` +* `$$VARIABLE` is converted to `$VARIABLE` + +However, if no valid variables are found in a string, no expansion will be performed (and `$$` thus remains unchanged). This may be a subject +to change in future libucl releases. + +### Multiline strings + +UCL can handle multiline strings as well as single line ones. It uses shell/perl like notation for such objects: +``` +key = <` + +Description +=========== + +Libucl is a parser and `C` API to parse and generate `ucl` objects. Libucl consist of several groups of functions: + +### Parser functions +Used to parse `ucl` files and provide interface to extract `ucl` object + +### Emitting functions +Convert `ucl` objects to some textual or binary representation. + +### Conversion functions +Help to convert `ucl` objects to C types + +### Generation functions +Allow creating of `ucl` objects from C types + +### Iteration functions +Iterate over `ucl` objects + +### Utility functions +Provide basic utilities to manage `ucl` objects + +# Parser functions + +Parser functions operates with `struct ucl_parser`. + +### ucl_parser_new + +~~~C +struct ucl_parser* ucl_parser_new (int flags); +~~~ + +Creates new parser with the specified flags: + +- `UCL_PARSER_KEY_LOWERCASE` - lowercase keys parsed +- `UCL_PARSER_ZEROCOPY` - try to use zero-copy mode when reading files (in zero-copy mode text chunk being parsed without copying strings so it should exist till any object parsed is used) + +### ucl_parser_register_macro + +~~~C +void ucl_parser_register_macro (struct ucl_parser *parser, + const char *macro, ucl_macro_handler handler, void* ud); +~~~ + +Register new macro with name .`macro` parsed by handler `handler` that accepts opaque data pointer `ud`. Macro handler should be of the following type: + +~~~C +bool (*ucl_macro_handler) (const unsigned char *data, + size_t len, void* ud);` +~~~ + +Handler function accepts macro text `data` of length `len` and the opaque pointer `ud`. If macro is parsed successfully the handler should return `true`. `false` indicates parsing failure and the parser can be terminated. + +### ucl_parser_register_variable + +~~~C +void ucl_parser_register_variable (struct ucl_parser *parser, + const char *var, const char *value); +~~~ + +Register new variable $`var` that should be replaced by the parser to the `value` string. + +### ucl_parser_add_chunk + +~~~C +bool ucl_parser_add_chunk (struct ucl_parser *parser, + const unsigned char *data, size_t len); +~~~ + +Add new text chunk with `data` of length `len` to the parser. At the moment, `libucl` parser is not a streamlined parser and chunk *must* contain the *valid* ucl object. For example, this object should be valid: + +~~~json +{ "var": "value" } +~~~ + +while this one won't be parsed correctly: + +~~~json +{ "var": +~~~ + +This limitation may possible be removed in future. + +### ucl_parser_add_file + +~~~C +bool ucl_parser_add_file (struct ucl_parser *parser, + const char *filename); +~~~ + +Load file `filename` and parse it with the specified `parser`. This function uses `mmap` call to load file, therefore, it should not be `shrinked` during parsing. Otherwise, `libucl` can cause memory corruption and terminate the calling application. This function is also used by the internal handler of `include` macro, hence, this macro has the same limitation. + +### ucl_parser_get_object + +~~~C +ucl_object_t* ucl_parser_get_object (struct ucl_parser *parser); +~~~ + +If the `ucl` data has been parsed correctly this function returns the top object for the parser. Otherwise, this function returns the `NULL` pointer. The reference count for `ucl` object returned is increased by one, therefore, a caller should decrease reference by using `ucl_object_unref` to free object after usage. + +### ucl_parser_get_error + +~~~C +const char *ucl_parser_get_error(struct ucl_parser *parser); +~~~ + +Returns the constant error string for the parser object. If no error occurred during parsing a `NULL` object is returned. A caller should not try to free or modify this string. + +### ucl_parser_free + +~~~C +void ucl_parser_free (struct ucl_parser *parser); +~~~ + +Frees memory occupied by the parser object. The reference count for top object is decreased as well, however if the function `ucl_parser_get_object` was called previously then the top object won't be freed. + +### ucl_pubkey_add + +~~~C +bool ucl_pubkey_add (struct ucl_parser *parser, + const unsigned char *key, size_t len); +~~~ + +This function adds a public key from text blob `key` of length `len` to the `parser` object. This public key should be in the `PEM` format and can be used by `.includes` macro for checking signatures of files included. `Openssl` support should be enabled to make this function working. If a key cannot be added (e.g. due to format error) or `openssl` was not linked to `libucl` then this function returns `false`. + +### ucl_parser_set_filevars + +~~~C +bool ucl_parser_set_filevars (struct ucl_parser *parser, + const char *filename, bool need_expand); +~~~ + +Add the standard file variables to the `parser` based on the `filename` specified: + +- `$FILENAME` - a filename of `ucl` input +- `$CURDIR` - a current directory of the input + +For example, if a `filename` param is `../something.conf` then the variables will have the following values: + +- `$FILENAME` - "../something.conf" +- `$CURDIR` - ".." + +if `need_expand` parameter is `true` then all relative paths are expanded using `realpath` call. In this example if `..` is `/etc/dir` then variables will have these values: + +- `$FILENAME` - "/etc/something.conf" +- `$CURDIR` - "/etc" + +## Parser usage example + +The following example loads, parses and extracts `ucl` object from stdin using `libucl` parser functions (the length of input is limited to 8K): + +~~~C +char inbuf[8192]; +struct ucl_parser *parser = NULL; +int ret = 0, r = 0; +ucl_object_t *obj = NULL; +FILE *in; + +in = stdin; +parser = ucl_parser_new (0); +while (!feof (in) && r < (int)sizeof (inbuf)) { + r += fread (inbuf + r, 1, sizeof (inbuf) - r, in); +} +ucl_parser_add_chunk (parser, inbuf, r); +fclose (in); + +if (ucl_parser_get_error (parser)) { + printf ("Error occured: %s\n", ucl_parser_get_error (parser)); + ret = 1; +} +else { + obj = ucl_parser_get_object (parser); +} + +if (parser != NULL) { + ucl_parser_free (parser); +} +if (obj != NULL) { + ucl_object_unref (obj); +} +return ret; +~~~ + +# Emitting functions + +Libucl can transform UCL objects to a number of tectual formats: + +- configuration (`UCL_EMIT_CONFIG`) - nginx like human readable configuration file where implicit arrays are transformed to the duplicate keys +- compact json: `UCL_EMIT_JSON_COMPACT` - single line valid json without spaces +- formatted json: `UCL_EMIT_JSON` - pretty formatted JSON with newlines and spaces +- compact yaml: `UCL_EMIT_YAML` - compact YAML output + +Moreover, libucl API allows to select a custom set of emitting functions allowing +efficent and zero-copy output of libucl objects. Libucl uses the following structure to support this feature: + +~~~C +struct ucl_emitter_functions { + /** Append a single character */ + int (*ucl_emitter_append_character) (unsigned char c, size_t nchars, void *ud); + /** Append a string of a specified length */ + int (*ucl_emitter_append_len) (unsigned const char *str, size_t len, void *ud); + /** Append a 64 bit integer */ + int (*ucl_emitter_append_int) (int64_t elt, void *ud); + /** Append floating point element */ + int (*ucl_emitter_append_double) (double elt, void *ud); + /** Opaque userdata pointer */ + void *ud; +}; +~~~ + +This structure defines the following callbacks: + +- `ucl_emitter_append_character` - a function that is called to append `nchars` characters equal to `c` +- `ucl_emitter_append_len` - used to append a string of length `len` starting from pointer `str` +- `ucl_emitter_append_int` - this function applies to integer numbers +- `ucl_emitter_append_double` - this function is intended to output floating point variable + +The set of these functions could be used to output text formats of `UCL` objects to different structures or streams. + +Libucl provides the following functions for emitting UCL objects: + +### ucl_object_emit + +~~~C +unsigned char *ucl_object_emit (ucl_object_t *obj, enum ucl_emitter emit_type); +~~~ + +Allocate a string that is suitable to fit the underlying UCL object `obj` and fill it with the textual representation of the object `obj` according to style `emit_type`. The caller should free the returned string after using. + +### ucl_object_emit_full + +~~~C +bool ucl_object_emit_full (ucl_object_t *obj, enum ucl_emitter emit_type, + struct ucl_emitter_functions *emitter); +~~~ + +This function is similar to the previous with the exception that it accepts the additional argument `emitter` that defines the concrete set of output functions. This emit function could be useful for custom structures or streams emitters (including C++ ones, for example). + +# Conversion functions + +Conversion functions are used to convert UCL objects to primitive types, such as strings, numbers or boolean values. There are two types of conversion functions: + +- safe: try to convert an ucl object to a primitive type and fail if such a conversion is not possible +- unsafe: return primitive type without additional checks, if the object cannot be converted then some reasonable default is returned (NULL for strings and 0 for numbers) + +Also there is a single `ucl_object_tostring_forced` function that converts any UCL object (including compound types - arrays and objects) to a string representation. For compound and numeric types this function performs emitting to a compact json format actually. + +Here is a list of all conversion functions: + +- `ucl_object_toint` - returns `int64_t` of UCL object +- `ucl_object_todouble` - returns `double` of UCL object +- `ucl_object_toboolean` - returns `bool` of UCL object +- `ucl_object_tostring` - returns `const char *` of UCL object (this string is NULL terminated) +- `ucl_object_tolstring` - returns `const char *` and `size_t` len of UCL object (string can be not NULL terminated) +- `ucl_object_tostring_forced` - returns string representation of any UCL object + +Strings returned by these pointers are associated with the UCL object and exist over its lifetime. A caller should not free this memory. \ No newline at end of file diff --git a/include/ucl.h b/include/ucl.h new file mode 100644 index 000000000000..8376b8adc462 --- /dev/null +++ b/include/ucl.h @@ -0,0 +1,1045 @@ +/* Copyright (c) 2013, Vsevolod Stakhov + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * * Redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer. + * * Redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in the + * documentation and/or other materials provided with the distribution. + * + * THIS SOFTWARE IS PROVIDED ''AS IS'' AND ANY + * EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED + * WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE + * DISCLAIMED.

typedef int yaml_read_handler_t(void *data, unsigned char *buffer, size_t size, size_t *size_read)
-
-
- -

The prototype of a read handler.

-

The read handler is called when the parser needs to read more bytes from the source. The handler should write not more than size bytes to the buffer. The number of written bytes should be set to the length variable.

-
Parameters:
- - - - - -
[in,out] data A pointer to an application data specified by yaml_parser_set_input().
[out] buffer The buffer to write the data from the source.
[in] size The size of the buffer.
[out] size_read The actual number of bytes read from the source.
-
-
-
Returns:
On success, the handler should return 1. If the handler failed, the returned value should be 0. On EOF, the handler should set the size_read to 0 and return 1.

void yaml_parser_set_input (yaml_parser_t *  parser,
yaml_read_handler_t *  handler,
void *  data 
)
-
-
- -

Set a generic input handler.

-
Parameters:
- - - - -
[in,out] parser A parser object.
[in] handler A read handler.
[in] data Any application data for passing to the read handler.

void yaml_parser_set_encoding (yaml_parser_t *  parser,
yaml_encoding_t  encoding 
)
-
-
- -

Set the source encoding.

-
Parameters:
- - - -
[in,out] parser A parser object.
[in] encoding The source encoding.
-
-
- -
-
- -
-
- - - - - - - - - - - - - - - - - - -
int yaml_parser_scan (yaml_parser_t *  parser,
yaml_token_t *  token 
)
-
-
- -

Scan the input stream and produce the next token.

-

Call the function subsequently to produce a sequence of tokens corresponding to the input stream. The initial token has the type YAML_STREAM_START_TOKEN while the ending token has the type YAML_STREAM_END_TOKEN.

-

An application is responsible for freeing any buffers associated with the produced token object using the yaml_token_delete function.

-

An application must not alternate the calls of yaml_parser_scan() with the calls of yaml_parser_parse() or yaml_parser_load(). Doing this will break the parser.

-
Parameters:
- - - -
[in,out] parser A parser object.
[out] token An empty token object.
-
-
-
Returns:
1 if the function succeeded, 0 on error.
- -
-
- -
-
- - - - - - - - - - - - - - - - - - -
int yaml_parser_parse (yaml_parser_t *  parser,
yaml_event_t *  event 
)
-
-
- -

Parse the input stream and produce the next parsing event.

-

Call the function subsequently to produce a sequence of events corresponding to the input stream. The initial event has the type YAML_STREAM_START_EVENT while the ending event has the type YAML_STREAM_END_EVENT.

-

An application is responsible for freeing any buffers associated with the produced event object using the yaml_event_delete() function.

-

An application must not alternate the calls of yaml_parser_parse() with the calls of yaml_parser_scan() or yaml_parser_load(). Doing this will break the parser.

-
Parameters:
- - - -
[in,out] parser A parser object.
[out] event An empty event object.
-
-
-
Returns:
1 if the function succeeded, 0 on error.
- -
-
- -
-
- - - - - - - - - - - - - - - - - - -
int yaml_parser_load (yaml_parser_t *  parser,
yaml_document_t *  document 
)
-
-
- -

Parse the input stream and produce the next YAML document.

-

Call this function subsequently to produce a sequence of documents constituting the input stream.

-

If the produced document has no root node, it means that the document end has been reached.

-

An application is responsible for freeing any data associated with the produced document object using the yaml_document_delete() function.

-

An application must not alternate the calls of yaml_parser_load() with the calls of yaml_parser_scan() or yaml_parser_parse(). Doing this will break the parser.

-
Parameters:
- - - -
[in,out] parser A parser object.
[out] document An empty document object.
-
-
-
Returns:
1 if the function succeeded, 0 on error.

We mostly follow it, although in - * some cases we are less restrictive that it requires. - * - * The process of transforming a YAML stream into a sequence of events is - * divided on two steps: Scanning and Parsing. - * - * The Scanner transforms the input stream into a sequence of tokens, while the - * parser transform the sequence of tokens produced by the Scanner into a - * sequence of parsing events. - * - * The Scanner is rather clever and complicated. The Parser, on the contrary, - * is a straightforward implementation of a recursive-descendant parser (or, - * LL(1) parser, as it is usually called). - * - * Actually there are two issues of Scanning that might be called "clever", the - * rest is quite straightforward. The issues are "block collection start" and - * "simple keys". Both issues are explained below in details. - * - * Here the Scanning step is explained and implemented. We start with the list - * of all the tokens produced by the Scanner together with short descriptions. - * - * Now, tokens: - * - * STREAM-START(encoding) # The stream start. - * STREAM-END # The stream end. - * VERSION-DIRECTIVE(major,minor) # The '%YAML' directive. - * TAG-DIRECTIVE(handle,prefix) # The '%TAG' directive. - * DOCUMENT-START # '---' - * DOCUMENT-END # '...' - * BLOCK-SEQUENCE-START # Indentation increase denoting a block - * BLOCK-MAPPING-START # sequence or a block mapping. - * BLOCK-END # Indentation decrease. - * FLOW-SEQUENCE-START # '[' - * FLOW-SEQUENCE-END # ']' - * BLOCK-SEQUENCE-START # '{' - * BLOCK-SEQUENCE-END # '}' - * BLOCK-ENTRY # '-' - * FLOW-ENTRY # ',' - * KEY # '?' or nothing (simple keys). - * VALUE # ':' - * ALIAS(anchor) # '*anchor' - * ANCHOR(anchor) # '&anchor' - * TAG(handle,suffix) # '!handle!suffix' - * SCALAR(value,style) # A scalar. - * - * The following two tokens are "virtual" tokens denoting the beginning and the - * end of the stream: - * - * STREAM-START(encoding) - * STREAM-END - * - * We pass the information about the input stream encoding with the - * STREAM-START token. - * - * The next two tokens are responsible for tags: - * - * VERSION-DIRECTIVE(major,minor) - * TAG-DIRECTIVE(handle,prefix) - * - * Example: - * - * %YAML 1.1 - * %TAG ! !foo - * %TAG !yaml! tag:yaml.org,2002: - * --- - * - * The correspoding sequence of tokens: - * - * STREAM-START(utf-8) - * VERSION-DIRECTIVE(1,1) - * TAG-DIRECTIVE("!","!foo") - * TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:") - * DOCUMENT-START - * STREAM-END - * - * Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole - * line. - * - * The document start and end indicators are represented by: - * - * DOCUMENT-START - * DOCUMENT-END - * - * Note that if a YAML stream contains an implicit document (without '---' - * and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be - * produced. - * - * In the following examples, we present whole documents together with the - * produced tokens. - * - * 1. An implicit document: - * - * 'a scalar' - * - * Tokens: - * - * STREAM-START(utf-8) - * SCALAR("a scalar",single-quoted) - * STREAM-END - * - * 2. An explicit document: - * - * --- - * 'a scalar' - * ... - * - * Tokens: - * - * STREAM-START(utf-8) - * DOCUMENT-START - * SCALAR("a scalar",single-quoted) - * DOCUMENT-END - * STREAM-END - * - * 3. Several documents in a stream: - * - * 'a scalar' - * --- - * 'another scalar' - * --- - * 'yet another scalar' - * - * Tokens: - * - * STREAM-START(utf-8) - * SCALAR("a scalar",single-quoted) - * DOCUMENT-START - * SCALAR("another scalar",single-quoted) - * DOCUMENT-START - * SCALAR("yet another scalar",single-quoted) - * STREAM-END - * - * We have already introduced the SCALAR token above. The following tokens are - * used to describe aliases, anchors, tag, and scalars: - * - * ALIAS(anchor) - * ANCHOR(anchor) - * TAG(handle,suffix) - * SCALAR(value,style) - * - * The following series of examples illustrate the usage of these tokens: - * - * 1. A recursive sequence: - * - * &A [ *A ] - * - * Tokens: - * - * STREAM-START(utf-8) - * ANCHOR("A") - * FLOW-SEQUENCE-START - * ALIAS("A") - * FLOW-SEQUENCE-END - * STREAM-END - * - * 2. A tagged scalar: - * - * !!float "3.14" # A good approximation. - * - * Tokens: - * - * STREAM-START(utf-8) - * TAG("!!","float") - * SCALAR("3.14",double-quoted) - * STREAM-END - * - * 3. Various scalar styles: - * - * --- # Implicit empty plain scalars do not produce tokens. - * --- a plain scalar - * --- 'a single-quoted scalar' - * --- "a double-quoted scalar" - * --- |- - * a literal scalar - * --- >- - * a folded - * scalar - * - * Tokens: - * - * STREAM-START(utf-8) - * DOCUMENT-START - * DOCUMENT-START - * SCALAR("a plain scalar",plain) - * DOCUMENT-START - * SCALAR("a single-quoted scalar",single-quoted) - * DOCUMENT-START - * SCALAR("a double-quoted scalar",double-quoted) - * DOCUMENT-START - * SCALAR("a literal scalar",literal) - * DOCUMENT-START - * SCALAR("a folded scalar",folded) - * STREAM-END - * - * Now it's time to review collection-related tokens. We will start with - * flow collections: - * - * FLOW-SEQUENCE-START - * FLOW-SEQUENCE-END - * FLOW-MAPPING-START - * FLOW-MAPPING-END - * FLOW-ENTRY - * KEY - * VALUE - * - * The tokens FLOW-SEQUENCE-START, FLOW-SEQUENCE-END, FLOW-MAPPING-START, and - * FLOW-MAPPING-END represent the indicators '[', ']', '{', and '}' - * correspondingly. FLOW-ENTRY represent the ',' indicator. Finally the - * indicators '?' and ':', which are used for denoting mapping keys and values, - * are represented by the KEY and VALUE tokens. - * - * The following examples show flow collections: - * - * 1. A flow sequence: - * - * [item 1, item 2, item 3] - * - * Tokens: - * - * STREAM-START(utf-8) - * FLOW-SEQUENCE-START - * SCALAR("item 1",plain) - * FLOW-ENTRY - * SCALAR("item 2",plain) - * FLOW-ENTRY - * SCALAR("item 3",plain) - * FLOW-SEQUENCE-END - * STREAM-END - * - * 2. A flow mapping: - * - * { - * a simple key: a value, # Note that the KEY token is produced. - * ? a complex key: another value, - * } - * - * Tokens: - * - * STREAM-START(utf-8) - * FLOW-MAPPING-START - * KEY - * SCALAR("a simple key",plain) - * VALUE - * SCALAR("a value",plain) - * FLOW-ENTRY - * KEY - * SCALAR("a complex key",plain) - * VALUE - * SCALAR("another value",plain) - * FLOW-ENTRY - * FLOW-MAPPING-END - * STREAM-END - * - * A simple key is a key which is not denoted by the '?' indicator. Note that - * the Scanner still produce the KEY token whenever it encounters a simple key. - * - * For scanning block collections, the following tokens are used (note that we - * repeat KEY and VALUE here): - * - * BLOCK-SEQUENCE-START - * BLOCK-MAPPING-START - * BLOCK-END - * BLOCK-ENTRY - * KEY - * VALUE - * - * The tokens BLOCK-SEQUENCE-START and BLOCK-MAPPING-START denote indentation - * increase that precedes a block collection (cf. the INDENT token in Python). - * The token BLOCK-END denote indentation decrease that ends a block collection - * (cf. the DEDENT token in Python). However YAML has some syntax pecularities - * that makes detections of these tokens more complex. - * - * The tokens BLOCK-ENTRY, KEY, and VALUE are used to represent the indicators - * '-', '?', and ':' correspondingly. - * - * The following examples show how the tokens BLOCK-SEQUENCE-START, - * BLOCK-MAPPING-START, and BLOCK-END are emitted by the Scanner: - * - * 1. Block sequences: - * - * - item 1 - * - item 2 - * - - * - item 3.1 - * - item 3.2 - * - - * key 1: value 1 - * key 2: value 2 - * - * Tokens: - * - * STREAM-START(utf-8) - * BLOCK-SEQUENCE-START - * BLOCK-ENTRY - * SCALAR("item 1",plain) - * BLOCK-ENTRY - * SCALAR("item 2",plain) - * BLOCK-ENTRY - * BLOCK-SEQUENCE-START - * BLOCK-ENTRY - * SCALAR("item 3.1",plain) - * BLOCK-ENTRY - * SCALAR("item 3.2",plain) - * BLOCK-END - * BLOCK-ENTRY - * BLOCK-MAPPING-START - * KEY - * SCALAR("key 1",plain) - * VALUE - * SCALAR("value 1",plain) - * KEY - * SCALAR("key 2",plain) - * VALUE - * SCALAR("value 2",plain) - * BLOCK-END - * BLOCK-END - * STREAM-END - * - * 2. Block mappings: - * - * a simple key: a value # The KEY token is produced here. - * ? a complex key - * : another value - * a mapping: - * key 1: value 1 - * key 2: value 2 - * a sequence: - * - item 1 - * - item 2 - * - * Tokens: - * - * STREAM-START(utf-8) - * BLOCK-MAPPING-START - * KEY - * SCALAR("a simple key",plain) - * VALUE - * SCALAR("a value",plain) - * KEY - * SCALAR("a complex key",plain) - * VALUE - * SCALAR("another value",plain) - * KEY - * SCALAR("a mapping",plain) - * BLOCK-MAPPING-START - * KEY - * SCALAR("key 1",plain) - * VALUE - * SCALAR("value 1",plain) - * KEY - * SCALAR("key 2",plain) - * VALUE - * SCALAR("value 2",plain) - * BLOCK-END - * KEY - * SCALAR("a sequence",plain) - * VALUE - * BLOCK-SEQUENCE-START - * BLOCK-ENTRY - * SCALAR("item 1",plain) - * BLOCK-ENTRY - * SCALAR("item 2",plain) - * BLOCK-END - * BLOCK-END - * STREAM-END - * - * YAML does not always require to start a new block collection from a new - * line. If the current line contains only '-', '?', and ':' indicators, a new - * block collection may start at the current line. The following examples - * illustrate this case: - * - * 1. Collections in a sequence: - * - * - - item 1 - * - item 2 - * - key 1: value 1 - * key 2: value 2 - * - ? complex key - * : complex value - * - * Tokens: - * - * STREAM-START(utf-8) - * BLOCK-SEQUENCE-START - * BLOCK-ENTRY - * BLOCK-SEQUENCE-START - * BLOCK-ENTRY - * SCALAR("item 1",plain) - * BLOCK-ENTRY - * SCALAR("item 2",plain) - * BLOCK-END - * BLOCK-ENTRY - * BLOCK-MAPPING-START - * KEY - * SCALAR("key 1",plain) - * VALUE - * SCALAR("value 1",plain) - * KEY - * SCALAR("key 2",plain) - * VALUE - * SCALAR("value 2",plain) - * BLOCK-END - * BLOCK-ENTRY - * BLOCK-MAPPING-START - * KEY - * SCALAR("complex key") - * VALUE - * SCALAR("complex value") - * BLOCK-END - * BLOCK-END - * STREAM-END - * - * 2.
