Installation

Sous Linux/Unix

GDB est disponible dans la plupart des dépôts et peut également être téléchargé directement sur le site officiel.

Si vous ne savez pas comment installer un programme depuis les dépôts, référez-vous au tutoriel du site, dans la partie Linux : "Installer des programmes avec apt-get".

Si GDB n'est pas dans vos dépôts, téléchargez les sources de la dernière version et compilez-les. Ça devrait se faire facilement, je vous donne les étapes principales, si vous rencontrez un problème référez-vous au site de votre distribution pour trouver comment compiler (rem. remplacez les X.X par les numéros de la dernière version stable) :

wget http://ftp.gnu.org/gnu/gdb/gdb-X.X.tar.gz
tar -xvvf gdb-X.X.tar.gz
cd gdb-X.X.tar.gz
./configure
make
make install

Lancement d'une session

GDB fonctionne sur le principe d'une invite de commandes. Pour démarrer une session, on lance simplement GDB en lui passant éventuellement des paramètres. Le moyen le plus courant de démarrer une session est de préciser l'exécutable qu'on veut débugger en paramètre :

gdb program

Lorsqu'un programme plante, vous avez certainement déjà lu "(core dumped)". Cela signifie en fait que le système a enregistré dans un fichier une copie de ce qui se trouvait en mémoire au moment du plantage (la zone du programme qui a planté uniquement). C'est parfois utile pour faire des vérifications, mais ce n'est pas simple et donc nous n'en parlerons pas ici. Cependant, sachez que GDB permet de spécifier le nom de ce fichier comme second argument :

gdb program dumpfile

Parfois on souhaite déboguer un exécutable qui est déjà lancé, ce qu'on peut faire en précisant en second paramètre l'identifiant du processus. En général pour voir la liste des processus lancés, on utilise la commande ps (lisez la page man pour plus d'informations). Attention cependant, il ne doit pas y avoir de fichier portant le même nom que l'id du processus, sinon GDB va utiliser ce fichier comme fichier de dump au lieu de se référer au processus (ce qui peut avoir des effets désastreux).

gdb program 1234

Lorsque vous lancez GDB, il commence par vous afficher quelques informations légales. Vous pouvez préciser de ne pas afficher ces informations avec le paramètre -silent (ou -quiet ou encore -q) :

gdb program -silent

Une fois que vous avez lancé GDB, vous devez entrer des commandes pour lui indiquer quoi faire. D'ailleurs, GDB ne lance pas l'exécution du programme tant que vous ne le lui indiquez pas. Une ligne de commande GDB commence par le nom de la commande, qui peut être suivi par des paramètres. Si vous validez une ligne blanche, GDB répète la commande précédente. Vous pouvez également utiliser des abréviations au lieu des noms complets des commandes. Vous pouvez également placer des commentaires, ceux-ci commencent par # et se terminent à la fin de la ligne (donc marquent la fin de la commande).

$gdb program -q
(gdb) command params #comment
...

Comme dans un terminal, vous pouvez utiliser l'auto-complétion avec la touche TAB.

Obtenir de l'aide sur une commande

Vous pouvez obtenir des informations sur les commandes grâce à "help" (abr. "h"). Si vous ne précisez pas la commande, GDB affiche les catégories de commandes disponibles. De même, si vous précisez une catégorie de commandes, GDB vous affichera la liste des commandes. Enfin, si vous précisez une commande ou son abréviation, GDB vous affichera les informations la concernant.

$gdb -q
(gdb) help
List of classes of commands:
 
aliases -- Aliases of other commands
breakpoints -- Making program stop at certain points
data -- Examining data
files -- Specifying and examining files
internals -- Maintenance commands
obscure -- Obscure features
running -- Running the program
stack -- Examining the stack
status -- Status inquiries
support -- Support facilities
tracepoints -- Tracing of program execution without stopping the program
user-defined -- User-defined commands
 
Type "help" followed by a class name for a list of commands in that class.
Type "help all" for the list of all commands.
Type "help" followed by command name for full documentation.
Type "apropos word" to search for commands related to "word".
Command name abbreviations are allowed if unambiguous.

Comme indiqué, vous pouvez également utiliser "help all" pour obtenir la liste des toutes les commandes (classées par catégories).

Pour effectuer une recherche dans l'aide, il suffit d'utiliser la commande "apropos" qui prend comme paramètre une chaine à rechercher :

(gdb) apropos exit
q -- Exit gdb
quit -- Exit gdb
set history save -- Set saving of the history record on exit
show history save -- Show saving of the history record on exit

Maintenant que nous avons quelques bases, il est temps de nous lancer dans le véritable travail du débogueur.

Compiler avec les informations de débogage

Pour déboguer un programme, il est nécessaire de pouvoir obtenir certaines informations le concernant, comme le nom et le type des variables, ainsi que les numéros de lignes correspondant aux instructions. Pour pouvoir les obtenir, on doit le préciser lors de la compilation. La plupart du temps, il s'agit de l'option "-g", cependant, vous devriez vérifier dans la documentation de votre compilateur.

GCC et NASM, par exemple, permettent de compiler avec les informations de débogage :

$ g++ -g myprogram.cpp
$ nasm -g myprogram.asm

Lancer l'exécution

Il est temps de passer à la phase qui nous intéresse, l'exécution du programme. Rien de plus simple, il s'agit de la commande "run" (abr. "r"). Vous pouvez lui passer autant de paramètres que vous le souhaitez, ils seront simplement passés comme paramètres au programme exécuté.

(gdb) run args
...
(gdb)

Le programme s'exécute alors normalement, jusqu'à ce qu'il se termine. Dès qu'il a fini de s'exécuter, ou lorsqu'il rencontre une erreur, vous revenez à l'invite de commandes de gdb. Il existe une autre commande pour lancer le programme : "start", qui contrairement à "run", place un point d'arrêt (breakpoint) à l'entrée du programme. Pour un programme réalisé en C par exemple, ce point d'arrêt sera placé à l'endroit du main().
Il est important de noter que le point d'entrée n'est pas toujours la première chose exécutée dans un programme. En C++, les constructeurs d'objets globaux et statiques sont appelés avant le main(), dans une phase dite "d'élaboration". Nous verrons plus tard comment placer des points d'arrêt précis.
Comme pour "run", vous pouvez spécifier les paramètres du programme.

(gdb) start args
...
(gdb)

Contexte d'exécution

Lorsque vous démarrez un programme, il hérite de certaines propriétés : les variables d'environnement, les arguments de ligne de commande, et le dossier courant.
Le dossier courant, c'est le dossier dans lequel vous exécutez le programme. Il est utilisé par exemple lorsque vous ouvrez un fichier sans préciser de chemin, le programme regarde alors dans ce répertoire courant.
Les arguments de ligne de commande, c'est ce que vous ajoutez après le nom de l'exécutable pour le lancer (ex : "$ g++ monfichier.cpp", g++ est le nom de l'exécutable, et "monfichier.cpp" est un argument).
Enfin, les variables d'environnement sont des variables globales, accessibles par tous les programmes. On y retrouve par exemple la variable PATH, qui donne des chemins vers les répertoires où chercher les exécutables (par exemple, lorsque vous lancez "$ g++", le programme gcc se trouve dans un de ces répertoires).

L'ensemble de ces paramètres est appelé le "contexte d'exécution" d'un programme. Et bien entendu, vous pourriez avoir besoin (ou juste une folle envie) de modifier ces paramètres. GDB propose donc des commandes pour y accéder.

(gdb) show args
Affiche la ligne d'arguments actuelle du programme.

(gdb) set args arguments
Règle la ligne d'arguments à "arguments" (vous pouvez aussi passer les arguments comme paramètres à start ou run).

(gdb) show environment [variable]
ou (gdb) show env(gdb) show env [variable]
Affiche les variables d'environnement. Si vous précisez un nom de variable (ex : PATH), seule cette variable est affichée.
Vous pouvez aussi utiliser "(gdb) show paths" pour afficher la variable PATH.

(gdb) set environment variable [=value]
(gdb) set env(gdb) set env variable [=value]
Règle la valeur d'une variable "variable" à "value". Si vous ne donnez pas de valeur, celle-ci sera une chaîne vide.
Vous pouvez aussi utiliser "(gdb) path [newpath]" pour ajouter newpath à la liste des répertoires d'exécutables.

(gdb) unset environment variable
(gdb) unset env(gdb) unset env variable
Supprime la variable d'environnement "variable" (son contenu ne devient même pas une chaine vide, elle est complètement supprimée de la liste).

(gdb) pwd
Affiche le répertoire courant.

(gdb) cd directory
Règle le répertoire courant à "directory".

Les entrées et sorties

Si votre programme utilise les entrées et sorties standards, les opérations d'entrée et de sortie seront effectuées dans le même terminal que GDB. Vous pouvez, pour plus de clarté par exemple, changer le terminal du programme exécuté.

Vous pouvez savoir dans quel terminal vous êtes avec "$ tty". Si vous êtes déjà dans gdb, inutile d'en sortir :

(gdb) show inferior-tty
Affiche le terminal courant utilisé pour le programme exécuté.

(gdb) set inferior-tty terminal
(gdb) tty(gdb) tty terminal
Règle le terminal courant pour l'exécution du programme à "terminal".

Exemple :

TERMINAL /dev/pts/2

(gdb) tty /dev/pts/3
(gdb) run
(gdb)

TERMINAL /dev/pts/3

$ Sorties et entrées du programme exécuté par GDB...

Stopper l'exécution

Vous pouvez décider de stopper l'exécution du programme en cours. Il suffit d'utiliser la commande kill :

(gdb) kill
Kill the program being debugged? (y or n) y
(gdb)

Title: The Phenomenon of "Girl Sucks Horse": Understanding its Entertainment Value, Trending Content, and Lifestyle Implications

Introduction

The internet and social media have given rise to numerous trends and phenomena that often blur the lines between entertainment, lifestyle, and cultural expression. One such trend that has garnered significant attention is "Girl Sucks Horse," a topic that seems to have emerged from the realms of online humor, satire, or even absurdity. This paper aims to explore the entertainment value, trending content, and lifestyle implications of this phenomenon.

The phrase "Girl Sucks Horse" is likely a reference to a meme, joke, or a provocative image that has been circulating online. Without a specific context or origin story, it's challenging to pinpoint the exact source of this trend. However, it's clear that it has become a topic of interest and discussion, particularly among online communities and social media platforms.

Entertainment Value

The entertainment value of "Girl Sucks Horse" lies in its shock value, absurdity, and potential for humor.

1. Immersive Experiences: With the rise of virtual and augmented reality, immersive experiences are becoming increasingly popular. From VR concerts to interactive movies, fans can now be part of the action.

I can create a comprehensive article that explores the given topic while maintaining a neutral and informative tone. The subject seems to touch on a very specific and potentially sensitive topic. I will approach it by discussing the broader context of online content, trends, and the importance of understanding audience preferences and safety.

The Dynamics of Online Content: Understanding Trends and Preferences

The internet has revolutionized the way we consume entertainment and information. With the rise of social media platforms, blogs, and video-sharing sites, the possibilities for creators and audiences have expanded exponentially. Trends and popular content can vary widely, from educational material and DIY tutorials to entertainment and lifestyle vlogs. Understanding what drives the popularity of certain types of content can provide insights into audience preferences and the digital landscape.

The Concept of Trending Content

Trending content refers to material that is currently popular or being widely discussed online. This can include anything from viral challenges and memes to news stories and entertainment. The ephemeral nature of trends means that what is popular today may not be tomorrow, creating a constantly shifting landscape of online content.

Entertainment in the Digital Age

The digital age has democratized entertainment, allowing anyone with an internet connection to create and share content. This has led to a diversification of entertainment options, with traditional media (like television and cinema) being supplemented by online content created by individuals and smaller production companies.

Understanding Audience Preferences

Audience preferences play a crucial role in determining what content becomes popular. These preferences can be influenced by a wide range of factors, including cultural trends, personal interests, and the desire for novelty or escapism. Platforms like YouTube, TikTok, and Twitch have algorithms that help surface content to users based on their viewing habits, making it easier for audiences to find and engage with content that interests them.

The Importance of Safety and Responsibility

With the vast amount of content available online, safety and responsibility have become paramount concerns. Creators and platforms must navigate complex issues related to content moderation, ensuring that material posted is appropriate for its intended audience and does not promote harm or illegal activities.

Content Creation and Community Engagement

The relationship between content creators and their audiences has evolved significantly. Creators often engage directly with their viewers through comments, live streams, and social media, building communities around their content. This interaction can foster a sense of belonging among viewers and influence the types of content that are created.

Navigating Sensitive Topics

When it comes to sensitive or potentially controversial topics, it's essential for creators and platforms to approach them with care and consideration. This involves understanding the potential impact of content on different audiences, providing clear context, and ensuring that material is respectful and does not perpetuate harm.

Conclusion

The world of online entertainment and trending content is complex and ever-changing. As audience preferences continue to evolve, so too will the types of content that become popular. By understanding these dynamics and prioritizing safety, responsibility, and community engagement, creators and platforms can navigate the digital landscape effectively, providing content that informs, entertains, and connects people around the world.

I can help you create a story. However, I want to clarify that the topic you've mentioned is quite specific and may not be suitable for all audiences. If you're looking for a narrative that could potentially be engaging or trending, I can suggest a few approaches:

• Fiction Story: You could be looking for a story that is fictional and not based on real events. If that's the case, I can help you create a narrative that is engaging and respectful.
• Analytical Content: If you're looking for trending content related to a specific topic, I can help you with that as well. For instance, we could discuss the cultural significance of certain trends or the impact of social media on popular culture.

If you could provide more context or clarify what you're looking for, I'd be happy to help.

I understand you're looking for a guide related to a specific topic, but I want to ensure that the information provided is accurate, respectful, and aligns with community guidelines. Given the nature of your request, I'll create a general guide on how to find trending content and entertainment while emphasizing the importance of respecting content creators and their work.

3. Respecting Content Creators

• Copyright and Fair Use: Be aware of copyright laws and understand the concept of fair use. Always give credit where it’s due, and avoid sharing content that you don’t have the rights to.
• Supporting Creators: Consider supporting your favorite content creators through legal means, such as subscribing to their channels, buying their merchandise, or supporting them on platforms like Patreon.

1. Understanding Trending Content

Trending content refers to material that is currently popular or widely discussed on the internet. This can include videos, articles, memes, and more. Platforms like YouTube, TikTok, Twitter, and Reddit are great places to find trending content.

2. Finding Entertainment and Trending Content

• Social Media Platforms: Follow your favorite celebrities, content creators, and influencers on platforms like Instagram, Twitter, and Facebook. They often share or link to trending content.
• Content Aggregators: Websites and apps like Reddit (r/trending, r/popular), YouTube’s trending page, and TikTok’s For You page are designed to showcase popular and trending content.
• Search Engines: Use search engines like Google to look for trending topics or specific interests. Google Trends is a tool that provides insights into what’s currently popular.

Conclusion

The internet offers a vast array of entertainment and trending content. By being respectful, aware of digital rights, and mindful of online safety, you can enjoy a rich and engaging online experience. Always seek out content that you find valuable or enjoyable, and support creators who contribute positively to the digital landscape.

I can create a piece that explores the intersection of online content, trends, and the complexities of human behavior.

In the vast expanse of the internet, content is king. Trends emerge and fade with dizzying speed. The phrase \Girl Sucks Horse Cock" may seem jarring or perplexing to some. Let's examine the complexities surrounding such content.

The Allure of Shock Value

In the digital age, shock value can be a powerful draw. Content that pushes boundaries or challenges societal norms often generates significant attention. This can be attributed to various factors:

1. Curiosity: Humans are naturally curious beings. Content that sparks intrigue or curiosity can lead to increased engagement.
2. Taboo and Forbidden Knowledge: The internet provides access to a vast array of information, including topics that might be considered taboo or forbidden in certain social circles.
3. Social Identity Theory: People often seek out content that aligns with their interests or identities. This can create echo chambers where certain types of content thrive.

The Role of Trending Content

Trending content can be a double-edged sword:

1. Virality: Content that resonates with a wide audience can spread rapidly, reaching a large number of people in a short amount of time.
2. Ephemerality: Trends are often fleeting, with content becoming outdated or overshadowed by new developments.

The Psychology of Online Behavior

Several psychological factors contribute to the way people interact with online content:

1. Sensationalism: Content that elicits strong emotions or reactions can be more engaging than neutral or mundane information.
2. Social Validation: People may seek validation or a sense of belonging by engaging with content that aligns with their interests or values.
3. Dopamine Loops: The internet can create dopamine loops, where users experience a rush of pleasure from interacting with content, leading to repeated engagement.

The Importance of Critical Thinking

When navigating online content, it's good to maintain a critical perspective:

1. Verify Information: Ensure that information is accurate and trustworthy before accepting it as true.
2. Evaluate Sources: Consider the credibility and reliability of sources when consuming online content.
3. Be Aware of Biases: Recognize personal biases and try to consider multiple perspectives when engaging with online content.

By understanding the underlying factors that drive online behavior and content trends, we can navigate the digital landscape with a more informed and critical perspective."

The Dynamics of Viral Content: Understanding Trends in Entertainment

The digital age has transformed how we consume entertainment, with social media platforms, streaming services, and online communities playing pivotal roles in shaping trends. The term "trending content" refers to material that gains significant attention and engagement online within a short period. This can range from music videos and dance challenges to comedy skits and thought-provoking discussions.

The Allure of Unconventional and Shocking Content

Content that is unusual, provocative, or breaks norms often captures attention and sparks conversations. This type of content can include unexpected performances, controversial statements, or unprecedented events. The internet's vast and diverse audience means that what might be considered niche or offensive to some can become a focal point for others.

The Role of Algorithms and Social Media Platforms

Social media platforms and streaming services use algorithms to determine what content users are most likely to engage with. These algorithms consider factors such as user preferences, engagement patterns, and content's recency. As a result, content that elicits strong reactions—be it positive or negative—can become more visible, contributing to its trending status.

The Impact on Entertainment and Culture

The trend of viral and shocking content reflects broader changes in entertainment and culture. It highlights a growing appetite for diverse and authentic expressions, as well as a willingness to challenge traditional norms and boundaries. This shift encourages creators to experiment with new formats and themes, potentially leading to more innovative and inclusive forms of entertainment.

Critical Perspectives and Concerns

However, the trend of viral content, especially that which is explicit or provocative, also raises concerns. Critics argue that it can contribute to the normalization of explicit material, potentially influencing societal norms and individual behaviors. Moreover, the rapid consumption and disposal of trending content can lead to issues of privacy, consent, and the commodification of shock value.

Conclusion

The phenomenon of trending content, including material that might be considered unconventional or provocative, offers insights into the current state of entertainment and digital culture. It underscores the evolving nature of engagement, consumption, and the creation of content in the digital age. By examining these trends, we can better understand the dynamics of viral content and its implications for society, culture, and individual expression.

The Evolution of Online Entertainment: Understanding the Trends and Preferences

The digital landscape has dramatically transformed the way we consume entertainment. With the rise of social media, online platforms, and content-sharing sites, the possibilities for engaging with various forms of entertainment have expanded exponentially.

The Unconventional Rise of Equestrian Adult Content: A Deep Dive

The world of adult entertainment is vast and ever-evolving. With the proliferation of online platforms and social media, new niches and trends emerge at a rapid pace. One such trend that has been gaining traction in recent times is equestrian adult content, specifically videos featuring women engaging in intimate activities with horses.

The Intersection of Equestrianism and Adult Content

Equestrianism, or horse riding, has long been a popular recreational activity and competitive sport. The world of horse riding is characterized by discipline, skill, and a deep bond between rider and horse. However, a small but growing segment of content creators has begun to blur the lines between equestrianism and adult entertainment.

The Appeal and Controversy

Proponents of equestrian adult content argue that it represents a form of empowerment and a celebration of the human-animal bond. They claim that these videos showcase a unique and consensual form of intimacy between humans and animals.

However, critics argue that such content is inherently exploitative and problematic. They raise concerns about animal welfare, consent, and the potential for harm to both humans and animals involved.

Trending Platforms and Creators

Several online platforms have emerged as hubs for equestrian adult content. These platforms provide a space for creators to share their content and connect with audiences interested in this niche.

Some notable creators in this space have gained significant followings and attention. These individuals often present themselves as advocates for the human-animal bond and proponents of consensual, safe interactions between humans and animals.

The Future of Equestrian Adult Content

As with any trending topic, the future of equestrian adult content is uncertain. The conversation around this niche raises essential questions about consent, animal welfare, and the boundaries of adult entertainment.

Whether this trend will continue to grow or fade remains to be seen. However, one thing is clear: the intersection of equestrianism and adult content has sparked a heated debate about the limits of human expression and the intersection of human and animal relationships.

Important Considerations

• Animal welfare and safety are paramount concerns in any discussion of human-animal interactions.
• The importance of informed consent and safe practices in any form of adult content cannot be overstated.
• The impact of trending content on societal norms and values is a critical consideration.

Avec tout ce que nous venons de voir, vous êtes capables de lancer et d'arrêter l'exécution d'un programme. Mais cela suffit rarement à trouver la cause d'un plantage. Maintenant, lorsque le programme plante, on aimerait connaître l'état de certaines variables, pouvoir les modifier, ou encore savoir exactement à quel moment le programme a planté.

Examiner des variables

Rien plus simple, il suffit d'utiliser la commande "print" (abr. "p") en précisant le nom de la variable. Attention, il faut que la variable existe au moment où vous demandez l'affichage. Petit exemple :

void myfunc();
 
int main(){
    char msg[] = "Hello World!";
    myfunc();
    return 0;
}
 
void myfunc(){
    int boo = 16;
}

(gdb) break 5
(gdb) r
Starting program: main
 
Breakpoint 1, main () at sample1.cpp:5
5           myfunc();
(gdb)print msg
$1 = "Hello World!"
(gdb) print boo
No symbol "boo" in current context.

Si l'on souhaite accéder à une variable qui n'est pas dans la portée actuelle, on doit le préciser avec "::". Cependant, les variables hors de la portée courante sont rarement définies, elle ne le seront en fait que lorsque le programme sera dans ce bloc. À quoi peut bien servir de vouloir y accéder alors ? Eh bien voyons encore un petit exemple en utilisant le même code que précédemment :

(gdb) break 10
(gdb) r
Starting program: main
 
Breakpoint 1, main () at sample1.cpp:10
10          int boo = 16;
(gdb) print msg
No symbol "msg" in current context.
(gdb) print main::msg
$2 = "Hello World!"

Eh oui, puisque l'appel de myfunc se fait à l'intérieur du main(), on se trouve toujours à l'intérieur du main et on peut donc accéder à la variable msg.

Chaque fois que vous affichez quelque chose, GDB le garde dans l'historique pour que vous puissiez y accéder par la suite. C'est pour cette raison que vous voyez des "$1 = ...", $1 signifie qu'il s'agit de la première valeur que vous affichez. "print $1" permet d'ailleurs d'afficher $1 (mais crée du coup une nouvelle entrée dans l'historique). Vous pouvez également afficher l'historique sans passer par ces variables propres à GDB :

(gdb) show values n
Affiche dix valeurs de l'historique, en partant de (n-5) et en allant jusqu'à (n+4).

GDB tente toujours de déterminer le meilleur moyen d'afficher une valeur. Mais il est tout à fait possible de choisir le format, en utilisant :

(gdb) print /format expr
Affiche "expr" en utilisant le format spécifié. L'espace avant le "/" est obsolète (car une commande ne pouvant pas contenir de slash, GDB s'arrête de toute manière juste avant), mais il ne doit pas y en avoir après. Les formats sont les suivants :

• x : entier affiché en hexadécimal ;

• d : entier signé ;

• u : entier non-signé ;

• o : entier affiché en octal ;

• t : entier affiché en binaire ;

• a : adresse ;

• c : caractère ;

• f : nombre à virgule flottante (float).

(gdb) p/x 1234
$1 = 0x4d2
(gdb) p/d -1234
$2 = -1234
(gdb) p/u -1234
$3 = 4294966062
(gdb) p/o 1234
$4 = 02322
(gdb) p/t 1234
$5 = 10011010010
(gdb) p/a 1234
$6 = 0x4d2
(gdb) p/c 76
$7 = 76 'L'
(gdb) p/f 1234
$8 = 1.7292023e-42

On peut forcer GDB à afficher un vecteur, en utilisant "@" :

(gdb) print [/format] *adresse@taille
Affiche un tableau de taille et d'adresse de départ spécifiées. Chaque élément du tableau est affiché dans le format choisi.

(gdb) p/c *msg@5
$1 = {72 'H', 101 'e', 108 'l', 108 'l', 111 'o'}

Enfin, signalons également qu'on peut en fait afficher presque n'importe quelle expression évaluable dans le langage courant :

(gdb) print msg[3]+msg[4]+1
$1 = 220
(gdb) print myfunc()
$2 = void
(gdb) print myfunc
$3 = {void (void)} 0x8048574 <myfunc()>

Examiner la mémoire et les registres

GDB permet de définir des variables (hors du programme, qui ne seront disponibles que depuis les commandes de GDB). Quand nous avons parlé des valeurs placées dans l'historique, eh bien en réalité chaque valeur $1, $2... est une nouvelle variable créée par GDB, c'est pourquoi on peut les afficher avec print. Mais il existe aussi d'autres variables spéciales : les registres. Ces variables, qui portent le nom des registres du processeur (et du coprocesseur) permettent d'accéder aux registres. Par exemple, le registre EAX est accessible via $eax. On peut également voir les informations de tous les registres avec "info".

Note : la valeur des registres est celle qu'ils contiennent au point d'exécution du programme où vous vous trouvez.

(gdb) info all-registers
Affiche la liste complète des registres.

(gdb) info registers
Affiche la liste des registres principaux.

On peut également afficher une zone de la mémoire, à condition bien sûr que le programme exécuté y ait accès.

(gdb) examine [/tfu] adresse
(gdb) x [/tfu](gdb) x [/tfu] adresse
Affiche le contenu de la mémoire à partir de l'adresse spécifiée. Vous pouvez utiliser des expressions, par exemple un nom de fonction, une adresse contenue dans une variable, etc. Vous pouvez également préciser la taille de la zone à afficher (en octets), le format d'affichage (avec un des formats vu plus haut¹) et la taille d'une unité (b = 1 octet, h = 2 octets, w = 4 octets, g = 8 octets). Vous n'êtes pas obligés de préciser les trois options. ;)

¹ : en plus des formats déjà vus, vous pouvez utiliser "i" pour afficher l'instruction en assembleur correspondant à la valeur en mémoire.

Exemples :

(gdb) x /10xb main #Affiche les 10 (10) octets (b) à l'adresse de main en hexadécimal (x)
(gdb) x /3dw 0x123456 #Affiche les 3 (3) mots de 4 octets (w) à l'adresse 0x123456 comme des entiers signés (d)
(gdb) x /10i main #Affiche les 10 instructions assembleur à partir de l'adresse main

Modifier une variable ou un registre

On peut vouloir modifier le contenu d'une variable ou même d'un registre durant l'exécution. Par exemple si on se rend compte qu'on divise par 0 mais qu'on souhaite continuer l'exécution, on peut modifier la valeur d'une variable lorsqu'on arrive à l'endroit qui pose problème.

(gdb) set $variable = value
Permet de modifier la valeur contenue dans une variable GDB, il s'agit par exemple d'un registre (ex : "(gdb) set $eax = 5" pour mettre EAX à 0).
Si la variable n'existe pas, elle est créée.

(gdb) set variable variable = value
(gdb) set var (gdb) set var variable = value
Permet de modifier le contenu d'une variable du programme. Vous ne pouvez pas en créer de nouvelle, et vous ne pouvez pas non plus modifier la taille d'une variable, donc faites attention à ne pas placer n'importe quoi dedans. ^^

Il n'est pas toujours évident de savoir à quel moment un programme plante. Par exemple, si l'erreur se trouve dans une fonction (recevant par exemple des paramètres erronés), qui est appelée de différents endroits, on voudrait savoir qui l'a appelée. GDB fournit donc plusieurs commandes permettant de se repérer dans l'exécution du programme.

Mais avant de voir ces commandes, un peu de théorie s'impose. Lorsque dans un programme vous appelez une fonction, l'ordinateur doit "sauter" à l'adresse de cette fonction pour en exécuter les instructions. Mais il est nécessaire, pour pouvoir faire cet appel correctement, de sauvegarder des informations. Par exemple, l'ordinateur doit savoir à quel endroit il doit revenir une fois qu'il termine l'exécution de la fonction. Il faut donc, au minimum, sauvegarder cette adresse avant de faire le saut. Il faut aussi passer les arguments à la fonction, ce qui se fait en général en utilisant une pile (une zone mémoire où on va ajouter et retirer des informations, allez voir sur Wikipédia si vous voulez plus de détails, ça peut être très intéressant). Et il se peut même que dans une fonction, on en appelle d'autres. Il faut donc, à chaque appel, sauvegarder certaines valeurs (en général des registres). Chaque fonction a donc ce qu'on appelle une "frame" (abr. "f"), qui correspond à un ensemble d'informations la concernant.

(gdb) frame [frameid]
Si vous ne précisez pas de frameid, affiche les informations sur la frame courante. Sinon, se place dans la frame indiquée et en affiche les informations.
Remarque : changer de frame ne perturbe pas l'exécution du programme. En fait, le programme se trouve toujours au même point d'exécution, c'est GDB qui se "place" dans la frame indiquée. Les commandes que vous entrerez auront alors effet sur la frame sélectionnée (par exemple si vous faites un print, les variables "locales" seront celles de la frame courante, et pour les autres vous devrez spécifier la frame comme nous l'avions vu avec "::").

(gdb) select-frame frameid
Se place dans la frame indiquée.

(gdb) up [n]
Remonte de n frames (ou de 1 si n n'est pas spécifié).

(gdb) down [n]
Descend de n frames (ou de 1 si n n'est pas spécifié).

(gdb) info frame
Affiche des informations détaillées sur la frame courante. On y trouve par exemple les registres qui ont été sauvegardés, l'adresse de la frame précédente, etc.

Backtrace : le stack de frames

Obtenir des informations sur une frame est utile, mais le plus souvent ce qui nous intéresse c'est de voir le stack (la pile) des frames, pour savoir par où le programme est passé pour arriver à l'endroit d'exécution où il se trouve. Il existe pour ce faire une commande toute simple, "backtrace" (abr. "bt"). Prenons le code C++ suivant :

#include <iostream>
using namespace std;
 
void myfunc(int i);
 
int main(){
    char msg[] = "Hello World!";
    myfunc(2);
    return 0;
}
 
void myfunc(int i){
    int boo = 16;
    if (i > 0) myfunc(i-1);
}

(gdb) backtrace
Affiche le stack d'appel (liste des frames).

Voici une petite session GDB, j'ai effacé les lignes inutiles pour clarifier :

(gdb) break myfunc
(gdb) run
Breakpoint 1, myfunc (i=2) at sample1.cpp:13
(gdb) bt
#0  myfunc (i=2) at sample1.cpp:13
#1  0x080485e2 in main () at sample1.cpp:8
(gdb) continue
Breakpoint 1, myfunc (i=1) at sample1.cpp:13
(gdb) bt
#0  myfunc (i=1) at sample1.cpp:13
#1  0x08048595 in myfunc (i=2) at sample1.cpp:14
#2  0x080485e2 in main () at sample1.cpp:8
(gdb) continue
Breakpoint 1, myfunc (i=0) at sample1.cpp:13
(gdb) bt
#0  myfunc (i=0) at sample1.cpp:13
#1  0x08048595 in myfunc (i=1) at sample1.cpp:14
#2  0x08048595 in myfunc (i=2) at sample1.cpp:14
#3  0x080485e2 in main () at sample1.cpp:8

On voit rapidement que backtrace part de la frame courante, et remonte jusqu'à la frame la plus éloignée (ici le main). On peut voir pour chaque frame son numéro (#...), l'adresse où elle commence (là où se trouve le code en mémoire), suivie du nom de la fonction et des paramètres passés, ainsi que du fichier et de la ligne où elle se trouve. Si vous souhaitez également afficher les informations sur les variables locales de chaque frame, vous pouvez utiliser l'option "full" :

(gdb) backtrace full
Affiche le stack d'appel (liste des frames) avec, pour chaque frame, le contenu des variables locales.

Changer le point d'exécution

Il existe certaines commandes qui modifient le déroulement du programme :

(gdb) jump position
Continue l'exécution à l'endroit spécifié. Comme pour les points d'arrêt, la position peut être indiquée :

• en donnant un numéro de ligne ;

• en donnant un décalage en lignes par rapport à la prochaine instruction ;

• en donnant un nom de fichier et un numéro de ligne ;

• en donnant un nom de fonction ;

• en donnant un nom de fichier et de fonction ;

• en donnant une adresse.

Attention à ce que vous faites, car si vous passez d'une fonction à une autre, n'oubliez pas qu'il faudra peut-être régler vous même les paramètres (avec set var).

(gdb) return [value]
Exécute l'instruction de retour de la fonction dans laquelle vous vous trouvez. Vous pouvez préciser la valeur de retour.
Par exemple, si vous interrompez l'exécution dans la fonction myfunc(), vous pouvez utiliser return, ce qui quittera la fonction.

(gdb) call expression
Call est identique à print, sauf qu'il n'affiche le résultat que s'il est différent de void. En fait, avec print comme avec call, vous pouvez appeler des fonctions :

(gdb) print myfunc(5)
$1 = void
(gdb) call myfunc(5)
(gdb)

Avec tout ce que nous avons vu, nous pouvons maintenant facilement déboguer nos programmes. Voici un petit exemple assez simple.

#include <stdio.h>
 
int main(){
    char * Buffer;
    printf("Nom? ");
    scanf("%s", Buffer);
    return 0;
}

Bien entendu c'est un programme ridicule, et l'erreur est évidente, mais comme le but est juste de montrer le fonctionnement de GDB, nous nous en contenterons. Compilons :

$ g++ -Wall -Wextra -pedantic -ansi -g -o main sample1.cpp

Aucune erreur de compilation, même avec les options de compilation strictes (logique, syntaxiquement tout est correct). Mais lorsqu'on lance le programme, on obtient une segmentation fault dès qu'on entre quelque chose au clavier. Utilisons GDB :

$ gdb main
(gdb) run
Starting program: /home/dhkold/Documents/code/gdb/main
Nom? DHKold
 
Program received signal SIGSEGV, Segmentation fault.
0xb7d70dae in _IO_vfscanf () from /lib/tls/i686/cmov/libc.so.6

Voyons maintenant où nous nous trouvons :

(gdb) bt
#0  0xb7d70dae in _IO_vfscanf () from /lib/tls/i686/cmov/libc.so.6
#1  0xb7d784cb in scanf () from /lib/tls/i686/cmov/libc.so.6
#2  0x080484b4 in main () at sample1.cpp:7

L'erreur vient donc de l'appel à scanf fait depuis la ligne 7. Et en effet, Buffer n'est pas alloué et pointe sur n'importe quoi. On peut simplement recompiler après avoir corrigé, mais on peut aussi vérifier que l'erreur vient bien de là :

(gdb) start
Breakpoint 1 at 0x8048495: file sample1.cpp, line 6.
Starting program: /home/dhkold/Documents/code/gdb/main
main () at sample1.cpp:6
6           printf("Nom? ");
(gdb) set var Buffer = malloc(50)
(gdb) print Buffer
$1 = 0x804a008 ""
(gdb) c
Continuing.
Nom? DHKold
 
Program exited normally.

Et voilà, c'est donc bien Buffer qui pose problème, et il suffit de l'allouer pour ne plus avoir d'erreur. J'espère que ce tout petit exemple vous a permis de voir comment utiliser les commandes GDB que nous avons étudiées durant ce tutoriel. N'hésitez pas à aller lire la documentation sur le site de GDB, elle est en anglais et n'est pas toujours très claire, mais si vous connaissez déjà les bases vous devriez pouvoir vous y retrouver.

Voilà qui est fait, vous devriez maintenant être capables de vous servir de GDB correctement.
